Rulemaking on Section 126 Petition From North Carolina To Reduce Interstate Transport of Fine Particulate Matter and Ozone; Federal Implementation Plans To Reduce Interstate Transport of Fine Particulate Matter and Ozone; Revisions to the Clean Air Interstate Rule; Revisions to the Acid Rain Program

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of proposed rulemaking (NPR).

SUMMARY: Today, EPA is proposing actions to address the interstate transport of emissions of nitrogen oxides (NOX) and sulfur dioxide (SO2) that contribute significantly to nonattainment and maintenance problems with respect to the national ambient air quality standards (NAAQS) for fine particulate matter (PM2.5) and 8-hour ozone. As one part of today's action, EPA is proposing its response to a petition submitted to EPA by the State of North Carolina under section 126 of the Clean Air Act (CAA). The petition requests that EPA find that SO2and/or NOXemissions from electric generating units (EGUs) in 13 States are significantly contributing to PM2.5and/or 8-hour ozone nonattainment and maintenance problems in North Carolina, and requests that EPA establish control requirements to prohibit such significant contribution. The EPA's proposed response is based on extensive analyses conducted for the recently issued Clean Air Interstate Rule (CAIR). The EPA is proposing to deny the petition for sources in States not shown to be linked to nonattainment and maintenance problems in North Carolina under the CAIR. For sources in States that are linked to North Carolina under the CAIR, EPA is proposing in the alternative to deny the petition if EPA promulgates Federal implementation plans (FIPs) to address the interstate transport no later than the final section 126 response or to grant the petition if EPA does not promulgate the FIPs prior to or concurrently with the section 126 response. The EPA's preferred option is to promulgate the FIP concurrently with the final section 126 response.

In today's action, EPA is also proposing FIPs for all jurisdictions that are covered by the CAIR. The FIPs would regulate EGUs in the affected States and achieve the emissions reductions requirements established by the CAIR until States have approved State implementation plans (SIPs) to achieve the reductions. The EPA intends the FIP to satisfy the concerns cited in the section 126 petition and provide a Federal backstop for the CAIR. In no way should the FIP for CAIR be viewed as a sign of any concern about States meeting the SIP responsibilities under CAIR.

As the control requirements for both the section 126 action and the FIP, EPA is proposing Federal NOXand SO2trading programs that provide emissions reductions equal to those required under the CAIR in affected States.

The Section 126 and FIP actions would not constrain States in their selection of control strategies to meet the CAIR. The EPA intends to withdraw section 126 or FIP requirements in a State if that State submits and EPA approves a SIP meeting the requirements of CAIR.

Today's action also proposes revisions to the CAIR in order to address the interaction between the EPA-administered Federal CAIR trading programs proposed today and the EPA-administered State CAIR trading programs that will be created by any State that elects to submit a SIP establishing such a trading program to meet the requirements of the CAIR. In addition, EPA is proposing revisions to the CAIR to correct certain minor errors.

Today's action also proposes revisions to the Acid Rain Program in order to make the administrative appeals procedures, which currently apply to final determinations by the Administrator under the EPA- administered State CAIR trading programs, also apply to the EPA- administered trading programs under the section 126 and FIP actions. In addition, we are proposing certain minor revisions to the Acid Rain Program that would apply to all affected units.

    I. Background and Summary of Proposal

1. Summary of Proposal

   Today, EPA is proposing two actions to address the interstate transport of emissions of NOXand SO2that contribute significantly to nonattainment and maintenance problems with respect to the NAAQS for PM2.5and 8-hour ozone. First, EPA is proposing its response to a petition submitted to EPA by the State of North Carolina under section 126 of the CAA. The petition requests that EPA establish control requirements for EGUs in 13 States based on findings that these sources are significantly contributing to PM2.5and/or 8-hour ozone nonattainment and maintenance problems in North Carolina. (See Petition, Docket No. OAR-2004-0076- 0002.)

   The EPA's proposed response is based on extensive analyses conducted for the CAIR (70 FR 25162; May 12, 2005). The EPA is proposing to deny the petition for sources in States not shown in the CAIR to be linked to (that is, to significantly contribute to) nonattainment and maintenance problems in North Carolina. For sources in States that are linked to North Carolina under the CAIR for the PM2.5NAAQS, EPA is proposing in the alternative (1) to deny the petition in the event that EPA promulgates FIPs no later than the final section 126 response to address the interstate transport or (2) to grant the petition if EPA does not promulgate a FIP prior to or concurrently with the section 126 response. The EPA's preferred approach is to promulgate the FIP concurrently with the final section 126 response and deny the petition. The FIP would control the significant transport from sources in States named in the petition as well as from sources in the other CAIR States, in the event that the States do not have approved SIPs meeting the CAIR requirements. The States named in the petition with respect to the PM2.5NAAQS are: Alabama, Georgia, Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia. Of these, Illinois and Michigan are not linked to North Carolina in the final CAIR. The EPA is proposing to deny the petition with respect to the 8-hour ozone NAAQS, because there are no States linked to North Carolina under the CAIR for that NAAQS. The States named in the petition with respect to the 8-hour ozone NAAQS are: Georgia, Maryland, South Carolina, Tennessee, and Virginia.

   In today's action, EPA is also proposing FIPs to address interstate transport of NOXand SO2under section 110(a)(2)(D) for all jurisdictions that are covered by the CAIR. In the CAIR, EPA determined that 28 States and the District of Columbia contribute significantly to nonattainment of the NAAQS for PM2.5and/or 8-hour ozone in downwind States. The CAIR explains EPA's basis for determining significant contribution to downwind nonattainment and maintenance problems. In that rule, the EPA required the affected upwind States to revise their SIPs to include control measures to reduce emissions of SO2and/or NOX. Sulfur dioxide is a precursor to PM2.5 formation, and NOXis a precursor to both ozone and PM2.5formation.

   In an action published on the same day as the final CAIR, EPA proposed to find that Delaware and New Jersey contribute significantly to PM2.5nonattainment and maintenance problems in downwind States considering these States as a single entity (70 FR 25408; May 12, 2005). These States were included in the final CAIR only with respect to their impacts on downwind 8-hour ozone problems. Today's FIP proposal includes emissions reductions requirements for Delaware and New Jersey that would address their significant contribution to nonattainment or maintenance problems for the PM2.5NAAQS if EPA ultimately finds that these States significantly contribute to PM2.5problems in downwind States based on the approach in the proposed rule cited above.

   The FIPs would regulate EGUs in the affected States and achieve the emissions reductions required by the CAIR until States have approved SIPs to achieve the reductions. The CAIR emissions budgets were based on control requirements that are highly cost effective for EGUs.

   The EPA intends the CAIR FIPs to satisfy the concerns cited in the section 126 petition and to provide a Federal backstop for CAIR. In no way should the FIPs for CAIR be viewed as a sign of any concern about States meeting the SIP responsibilities under CAIR. There are no sanctions associated with these FIPs and EPA does not intend CAIR FIPs to have any other negative consequences for the affected States. The EPA is proposing FIP approaches that are flexible and intended to provide States options for getting their SIPs in place.

   As the control remedy for both the section 126 action (should EPA make positive findings under section 126(b)) and the FIP, EPA is proposing Federal NOXand SO2cap and trade programs that provide the emissions reductions required by the CAIR. The trading programs are designed after the model cap and trade programs that EPA provided as a control option for States to meet the CAIR. The EPA intends to integrate the Federal trading programs with the EPA-administered State CAIR trading programs that are based on the model rules so that sources could trade with one another under the respective emissions caps.

   The EPA emphasizes that the section 126 response and FIP would not limit the options available to States to meet the requirements of the CAIR. We do not intend to record NOXallocations in sources' allowance accounts (or take any other steps to implement the section 126 or FIP requirements that could impact a State's ability to regulate their sources in a different manner) until more than a year after the CAIR SIP submission deadline.\1\ This would allow EPA time

   [[Page 49712]]

   to take rulemaking action to approve timely SIPs and, thus, the FIP or section 126 requirements would not go into place. In addition, States could replace the FIP or section 126 requirements at a later time.

   \1\ The CAIR requires affected sources to begin monitoring one year before the initial control periods (i.e., sources begin monitoring in 2008 for the NOXprograms and begin monitoring in 2009 for the SO2program). Note that EPA would take any necessary actions to implement the monitoring provisions of the proposed Federal trading rules in time for monitoring to begin in 2008. To the extent that a State chooses to control EGUs to meet its CAIR obligations, the monitoring requirements would be identical whether EPA regulated EGUs through the proposed Federal trading programs or the State regulated EGUs through their SIP.

   In today's action, EPA is also proposing revisions to the CAIR in order to address the interaction of EPA-administered NOXand SO2trading programs under the CAIR and under the section 126 and FIP actions. In addition, EPA is proposing some revisions to the CAIR in order to correct certain minor errors.

   The EPA is also proposing revisions to the Acid Rain Program in order to make the administrative appeals procedures (in 40 CFR part 78), which currently apply to final determinations by the Administrator under the EPA-administered States CAIR trading programs, also apply to the EPA-administered trading programs under the section 126 and FIP actions. In addition, EPA is proposing some minor revisions that would apply to all affected units under the Acid Rain Program.

   For purposes of the section 126 and FIP rulemakings, the EPA is not accepting comment on the CAIR or otherwise reopening any issue decided in the CAIR for reconsideration or comment, except that we are taking comment specifically on revisions to the CAIR that EPA is proposing in today's action. Section VII of this preamble discusses the proposed changes to the CAIR.

2. General Background on PM2.5 and Ozone

   1. The PM2.5Problem

   In an action published on July 18, 1997, we revised the NAAQS for particulate matter (PM) to add new standards for fine particles, using as the indicator particles with aerodynamic diameters smaller than a nominal 2.5 micrometers, termed PM2.5(62 FR 38652). We established health- and welfare-based (primary and secondary) annual and 24-hour standards for PM2.5. The annual standard is 15 micrograms per cubic meter, based on the 3-year average of annual mean PM2.5concentrations. The 24-hour standard is 65 micrograms per cubic meter, based on the 3-year average of the annual 98th percentile of 24-hour concentrations. The annual standard is generally considered the more limiting.

   Fine particles are associated with a number of serious health effects including premature mortality, aggravation of respiratory and cardiovascular disease (as indicated by increased hospital admissions, emergency room visits, absences from school or work, and restricted activity days), lung disease, decreased lung function, asthma attacks, and certain cardiovascular problems. (See EPA, Air Quality Criteria for Particulate Matter (EPA/600/P-99/002bF, October 2004) at 9.2.2.3). The EPA has estimated that attainment of the PM2.5standards would prolong tens of thousands of lives and would prevent, each year, tens of thousands of hospital admissions as well as hundreds of thousands of doctor visits, absences from work and school, and respiratory illnesses in children.

   Individuals particularly sensitive to fine particle exposure include older adults, people with heart and lung disease, and children. More detailed information on health effects of fine particles can be found on EPA's Web site at: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.htm1 .

   The secondary or welfare-based PM2.5standards are designed to protect against major environmental effects caused by PM such as visibility impairment--including in Class I areas which include national parks and wilderness areas across the country--soiling, and materials damage.

   As discussed in other sections of this preamble, SO2and NOXemissions both contribute to fine particle concentrations. In addition, NOXemissions contribute to ozone concentrations, described in the next section.

   The PM2.5ambient air quality monitoring for the 2001- 2003 period shows that areas violating the standards are located across much of the eastern half of the United States and in parts of California and Montana. The EPA published the PM2.5 attainment and nonattainment designations on January 5, 2005 (70 FR 944). 2. The 8-Hour Ozone Problem

   In an action published on July 18, 1997, we promulgated identical revised primary and secondary ozone standards that specified an 8-hour ozone standard of 0.08 parts per million (ppm). Specifically, under the standards, the 3-year average of the fourth highest daily maximum 8- hour average ozone concentration may not exceed 0.08 ppm. In general, the revised 8-hour standards are more protective of public health and the environment and more stringent than the pre-existing 1-hour ozone standards.

   Short-term (1- to 3-hour) and prolonged (6- to 8-hour) exposures to ambient ozone have been linked to a number of adverse health effects. Short-term exposure to ozone can irritate the respiratory system, causing coughing, throat irritation, and chest pain. Ozone can reduce lung function and make it more difficult to breathe deeply. Breathing may become more rapid and shallow than normal, thereby limiting a person's normal activity. Ozone also can aggravate asthma, leading to more asthma attacks that require a doctor's attention and the use of additional medication. Increased hospital admissions and emergency room visits for respiratory problems have been associated with ambient ozone exposures. Longer-term ozone exposure can inflame and damage the lining of the lungs, which may lead to permanent changes in lung tissue and irreversible reductions in lung function. A lower quality of life may result if the inflammation occurs repeatedly over a long time period (such as months, years, a lifetime). Recent epidemiological studies have shown a correlation between acute ozone exposures and increased risk of premature death.

   People who are particularly susceptible to the effects of ozone include people with respiratory diseases, such as asthma, and people with unusual sensitivity to ozone. Those who are exposed to higher levels of ozone include adults and children who are active outdoors.

   In addition to causing adverse health effects, ozone affects vegetation and ecosystems, leading to reductions in agricultural crop and commercial forest yields; reduced growth and survivability of tree seedlings; and increased plant susceptibility to disease, pests, and other environmental stresses (e.g., harsh weather). In long-lived species, these effects may become evident only after several years or even decades and have the potential for long-term adverse impacts on forest ecosystems. Ozone damage to the foliage of trees and other plants can also decrease the aesthetic value of ornamental species used in residential landscaping, as well as the natural beauty of our national parks and recreation areas. The economic value of some welfare losses due to ozone can be calculated, such as crop yield loss from both reduced seed production (e.g., soybean) and visible injury to some leaf crops (e.g., lettuce, spinach, tobacco), as well as visible injury to ornamental plants (i.e., grass, flowers, shrubs). Other types of welfare loss may not be quantifiable (e.g., reduced aesthetic value of trees growing in heavily visited national parks). More detailed information on health effects of ozone can be found at the following EPA Web

   [[Page 49713]]

   site: http://www.epa.gov/ttn/naaqs/standards/ozone/s_o3_index.html.

   Presently, wide geographic areas, including most of the nation's major population centers, experience ozone levels that violate the NAAQS for 8-hour ozone. These areas include much of the eastern part of the United States and large areas of California. The EPA published the 8-hour ozone attainment and nonattainment designations in the Federal Register on April 30, 2004 (69 FR 23858). 3. Other Environmental Effects Associated With SO2and NOXEmissions

   In addition to the enumerated human health and welfare benefits resulting from reductions in ambient levels of PM2.5and ozone, reductions in NOXand SO2will contribute to substantial visibility improvements in many parts of the eastern United States. Reductions in these pollutants will also reduce acidification and eutrophication of water bodies in the region. In addition, reducing emissions of NOXand SO2from EGUs can be expected to reduce emissions of mercury. Reduced mercury emissions in turn may reduce mercury loadings in lakes and thereby potentially decrease both human and wildlife exposure to fish containing mercury.

3. What Is the Statutory and Regulatory Background for Today's Action?

   1. What Is the ``Good Neighbor'' Provision?

   Following promulgation of new or revised NAAQS, the CAA requires all areas, regardless of their designation as attainment, nonattainment, or unclassifiable, to submit SIPs containing provisions specified under section 110(a)(2). Among these requirements are those specified by the so-called ``good neighbor'' provision section 110(a)(2)(D) which addresses interstate transport of air pollution.

   Section 110(a)(2)(D) requires that a SIP contain adequate provisions--

   (i) Prohibiting, consistent with the provisions of this title, any source or other type of emissions activity within the State from emitting any air pollutant in amounts which will--

   (I) Contribute significantly to nonattainment in, or interfere with maintenance by, any other State with respect to [any] national primary or secondary ambient air quality standard, or

   (II) Interfere with measures required to be included in the applicable implementation plan for any other State under part C to prevent significant deterioration of air quality or to protect visibility.

   (ii) Insuring compliance with the applicable requirements of sections 126 and 115 (relating to interstate and international pollution abatement);

   Section 110(a)(2)(D) is the underlying provision for EPA's CAIR and today's proposed section 126 and FIP actions. Under the CAIR, EPA established the amount of SO2and NOXemissions that each CAIR-affected State must prohibit through SIP revisions to address interstate transport with respect to the PM2.5and 8-hour ozone NAAQS. 2. What Is the CAA Section 126 Provision?

   Subsection (a) of section 126 requires, among other things, that SIPs require major proposed new (or modified) stationary sources to notify nearby States for which the air pollution levels may be affected by the fact that such sources have been permitted to commence construction. Subsection (b) provides:

   Any State or political subdivision may petition the Administrator for a finding that any major source or group of stationary sources emits or would emit any air pollutant in violation of the prohibition of section 110(a)(2)(D)(ii) * * * or this section.* * *

   Subsection (c) of section 126 states that--

   [I]t shall be a violation of this section and the applicable implementation plan in such State [in which the source is located or intends to locate]--

   (1) For any major proposed new (or modified) source with respect to which a finding has been made under subsection (b) to be constructed or to operate in violation of this section and the prohibition of section 110(a)(2)(D)(ii) \2\ or this section, or

   \2\ While the text of section 126 refers to section 110(a)(2)(D)(ii), EPA believes that this cross-reference is a scrivener's error that occurred during the 1990 Amendments to the CAA and that Congress intended to refer to section 110(a)(2)(D)(i). (See 64 FR 28267.) The EPA's interpretation was upheld in Appalachian Power Co. v. EPA, 249 F. 3d 1032, 1040-44 (DC Cir. 2001).

   (2) For any major existing source to operate more than three months after such finding has been made with respect to it.

   However, subsection (c) further provides that EPA may permit the continued operation of such major existing sources beyond the 3-month period, if such sources comply with EPA-promulgated emissions limits within 3 years of the date of the finding. 3. What Is EPA's Previous Section 126 Rulemaking?

   The EPA has previously taken action under section 126 to address interstate ozone transport (64 FR 28250; May 25, 1999) and (65 FR 2674; January 18, 2000). Because there are many parallels between that earlier action and today's proposal, we briefly discuss our earlier action here.

   Like the present rulemaking, EPA's previous section 126 rulemaking, dealing with interstate transport of NOX, occurred essentially in conjunction with an EPA rulemaking dealing with interstate transport of the same pollutants, the NOXSIP Call (62 FR 60318; November 7, 1997). As in today's rule, EPA concluded that section 126 and section 110(a)(2)(D)(i) are integrally connected (due to the reference to the section 110(a)(2)(D) prohibition found in section 126(b)). Thus, the interstate transport problem at issue could be addressed under either provision, and once the underlying section 110(a)(2)(D) SIP deficiency is eliminated, there no longer is a basis for EPA to make a positive finding under section 126. (See sections II and III below for a more detailed discussion.) In the earlier rulemaking, we therefore concluded that emissions reductions sufficient to eliminate a section 110(a)(2)(D) SIP deficiency would also be sufficient to satisfy section 126. The NOXSIP Call required SIP revisions eliminating the amount of emissions that contribute significantly to nonattainment in downwind States, the amount of emissions reductions corresponding to the quantity of emissions that could be eliminated by the application of highly cost-effective controls on specified sources in each upwind State. The section 126 remedy consequently called for the same set of highly cost-effective controls for the section 126 source categories, based on the record of the NOXSIP Call. We are adopting this same conceptual approach in today's rulemaking.

   There are also parallels between our earlier section 126 action and this action with regard to timing of actions in the section 126 proceeding and in the closely-related interstate transport proceeding under section 110(a)(2)(D). Because a section 126 finding turns on the existence of a section 110(a)(2)(D) deficiency, in the May 1999 Section 126 Rule, we determined which petitions had technical merit, but we stopped short of granting the findings for the petitions. Instead, we stated that because we had promulgated the NOXSIP Call, as long as an upwind State remained on track to comply with that rule, EPA would defer making the section 126 findings. Thus, the Section 126 Rule included a provision under which the rule would be automatically withdrawn for sources in a State once that State submitted and EPA fully approved a SIP that complied with the NOXSIP Call or if EPA promulgated a FIP to achieve the emissions reductions. (See 64 FR 28271-28274.) The reason

   [[Page 49714]]

   for this withdrawal would be the fact that the affected State's SIP revision or EPA's promulgated FIP would fulfill the section 110(a)(2)(D) requirements, so that there would no longer be any basis for the section 126 finding with respect to that State. Later judicial action staying the NOXSIP Call rule resulted in EPA granting the section 126 petitions at issue, but the new rule retained the basic linkage between section 126 and section 110(a)(2)(D) by providing that EPA would withdraw the section 126 findings upon EPA approval of a SIP satisfying the emission reduction requirements of the NOXSIP Call rule or upon EPA's promulgation of a FIP that achieved the emissions reductions. (See 65 FR at 2683 and Appalachian Power v. EPA, 249 F. 3d 1032, 1039 (DC Cir. 2001).) Similarly, in today's rulemaking, we are proposing to deny the section 126 petition if we approve SIPs which satisfy the emission reduction requirements of the CAIR, or if we promulgate a FIP which includes the emission reduction requirements of the CAIR.

   Finally, in the earlier section 126 rule, EPA adopted as a remedy for section 126 a Federal NOXcap and trade program patterned after the model NOXcap and trade program that EPA developed for States as an option to meet their NOXSIP Call requirements. The EPA is proposing the same approach here in the event that it grants North Carolina's section 126 petition. 4. What Is the Clean Air Interstate Rule?

   The EPA developed the Clean Air Interstate Rule (CAIR) to address interstate pollution transport with respect to the newly adopted PM2.5and 8-hour ozone NAAQS. The EPA published the proposals for CAIR (previously referred to as the Interstate Air Quality Rule) on January 30, 2004 (69 FR 4566) and June 10, 2004 (69 FR 32684), a notice of data availability on August 6, 2004 (69 FR 47828), and the final rule on May 12, 2005 (70 FR 25162). The EPA is providing this description of the CAIR to help place today's proposal in context. As stated above, EPA is not accepting comment on the CAIR or otherwise reopening any issue decided in the CAIR for reconsideration or comment, except that EPA is taking comment specifically on the revisions to CAIR that EPA is proposing in today's action (Section VII in this preamble discusses the proposed changes to CAIR).

   In the CAIR, based on air quality modeling analyses and cost analyses, EPA concluded that SO2and NOX emissions in certain States in the eastern part of the country, through the phenomenon of air pollution transport,\3\ contribute significantly to PM2.5and/or 8-hour ozone nonattainment and maintenance problems in downwind States. The CAIR establishes emission reduction requirements for the affected upwind States under CAA section 110(a)(2)(D). The affected States and the District of Columbia have until September 11, 2006 to adopt and submit SIP revisions to achieve these required reductions. The SIP revision must contain measures that will assure that sources in the State reduce their SO2and/ or NOXemissions sufficiently to eliminate the amounts of SO2and NOXthat contribute significantly to nonattainment downwind. Reducing upwind precursor emissions will assist the downwind PM2.5and 8-hour ozone areas in achieving and maintaining the NAAQS. Moreover, attainment will be achieved in a more equitable, cost-effective manner than if each nonattainment area attempted to achieve attainment by implementing local emissions reductions alone.

   \3\ When we use the term ``transport'' we mean to include the transport of both fine particles (PM2.5) and their precursor emissions and/or transport of both ozone and its precursor emissions.

   The EPA specified that the CAIR emissions reductions be implemented in two phases. The first phase of NOXreductions starts in 2009 (covering 2009-2014) and the first phase of SO2 reductions starts in 2010 (covering 2010-2014); the second phase of reductions for both NOXand SO2starts in 2015 (covering 2015 and thereafter). The emissions reduction requirements are based on controls that are known to be highly cost effective for EGUs, however States have the flexibility to determine what measures to adopt to achieve the necessary reductions. In the CAIR, EPA provided model SO2and NOXtrading programs for EGUs that States can choose to adopt to meet the emissions reduction requirements in a flexible and highly cost-effective manner.

   If EPA ultimately includes Delaware and New Jersey in the CAIR with respect to the PM2.5NAAQS (see proposal at 70 FR 25408), EPA estimates that the CAIR would reduce SO2emissions by 3.6 million tons in 2010 and by 3.9 million tons in 2015; and would reduce annual NOXemissions by 1.2 million tons in 2009 and by 1.5 million tons in 2015. (These numbers reflect the annual SO2and NOXrequirements.) If all these States (including Delaware and New Jersey for the PM2.5NAAQS) choose to achieve these reductions through EGU controls, then EGU SO2emissions in the affected States would be capped at 3.7 million tons in 2010 and 2.6 million tons in 2015; \4\ and EGU annual NOXemissions would be capped at 1.5 million tons in 2009 and 1.3 million tons in 2015.

   \4\ It should be noted that the banking provisions of the cap and trade program which encourage sources to make significant reductions before 2010 also allow sources to operate above these cap levels until all of the banked allowances are used, therefore EPA does not project that these caps will be met in 2010 or 2015.

   Based on the promulgated CAIR (70 FR 25162), EPA estimates that the required SO2and NOXemissions reductions would, by themselves, bring into attainment 52 of the 79 counties that are otherwise projected to be in nonattainment for PM2.5in 2010, and 57 of the 74 counties that are otherwise projected to be in nonattainment for PM2.5in 2015. The EPA further estimates that the required NOXemissions reductions would, by themselves, bring into attainment 3 of the 40 counties that are otherwise projected to be in nonattainment for 8-hour ozone in 2010, and 6 of the 22 counties that are projected to be in nonattainment for 8-hour ozone in 2015. In addition, the CAIR will improve PM2.5and 8-hour ozone air quality in the areas that would remain nonattainment for those two NAAQS after implementation of the CAIR. Because of CAIR, the States with those remaining nonattainment areas will find it less burdensome and less expensive to reach attainment by adopting additional controls. The CAIR will also reduce PM2.5and 8-hour ozone levels in attainment areas, providing significant health and environmental benefits in all areas of the eastern United States.

   For a more complete description of the CAIR and its impacts, the reader is encouraged to review the preamble to the CAIR. 5. What Are the Findings of Failure To Submit for the Section 110(a)(2)(D) Plans?

   In a final rule published on April 25, 2005 (70 FR 21147), we made national findings that States have failed to submit SIPs required under section 110(a)(2)(D) to address interstate transport with respect to the 8-hour ozone and PM2.5NAAQS.

   The April 25, 2005 findings started a 2-year clock for EPA to promulgate a Federal implementation plan (FIP) to address the requirements of section 110(a)(2)(D). Under section 110(c)(1), EPA may issue a FIP any time after such findings are made and must do so unless a SIP revision correcting the deficiency is approved by EPA before the FIP is promulgated. The EPA

   [[Page 49715]]

   intends to issue guidance regarding how States outside the CAIR region could satisfy the section 110(a)(2)(D) requirement. For States affected by CAIR, an approved SIP meeting the CAIR requirements would satisfy the requirement and turn off the FIP clock. As discussed below in section IV, EPA is today proposing a FIP for States affected by the CAIR. The EPA intends to promulgate the CAIR FIP by March 15, 2006 along with the final section 126 response. However, EPA intends to withdraw the FIP in a State in coordination with approval of a SIP for the State that meets the CAIR requirements.

   The findings do not start a sanctions clock pursuant to section 179 because the findings do not pertain to a part D plan for nonattainment areas required under section 110(a)(2)(I) and because the action is not a SIP Call pursuant to section 110(k)(5).

4. Summary of North Carolina's Section 126 Petition

   1. What Sources Does the Petition Target?

   The North Carolina petition requests relief from certain emissions from large EGUs located in 13 States. With respect to the PM2.5NAAQS, the petition requests that EPA find that NOXand SO2emissions from large EGUs in 12 States (Alabama, Georgia, Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia) are significantly contributing to nonattainment in, or interfering with maintenance by, North Carolina. With respect to the 8-hour ozone NAAQS, the petition requests that EPA find that NOXemissions from large EGUs in 5 States (Georgia, Maryland, South Carolina, Tennessee, and Virginia) are significantly contributing to nonattainment in, or interfering with maintenance by, North Carolina (Petition, p.1.)

   The petition defines the term ``EGUs'' as all facilities meeting the criteria described in the proposal for the CAIR. (See 69 FR 4566, 4610; January 30, 2004.) In the proposal for the CAIR, we defined EGUs as ``fossil-fuel fired boilers and turbines serving an electric generator with a nameplate capacity of greater than 25 megawatts (MW) producing electricity for sale.'' (Id.) (See section VII of today's preamble for clarification of the EGU definition.\5\)

   \5\ As noted in section VII below, EPA is proposing to amend the definition of EGU to remove certain ambiguities regarding the definition's application to solid waste incinerators and to existing units that formerly generated electricity for sale but have not done so since before November 15, 1990. We understand the North Carolina section 126 petition as applying only to the sources included in the clarified definition and not to sources we are proposing to exclude from the definition of EGU.

   2. What Control Remedy Does the Petition Request?

   In its petition, North Carolina states that compliance with the NOXand SO2emissions budgets in the proposal for the CAIR would satisfy the requirements of the petition. These emissions budgets were based on controls that are highly cost effective for EGUs. North Carolina also states that it does not oppose the flexibility discussed by EPA (69 FR at 4622) to allow equivalent reductions from other source categories in given States, so long as those reductions are real and enforceable (Petition, p. 24).

   In the CAIR, EPA provided model NOXand SO2 cap and trade programs for EGUs as control options for States to choose to meet the CAIR emissions reductions requirements. The trading programs allow interstate trading among sources in all States subject to the CAIR that adopt the programs. In its petition, North Carolina said it recognizes the value of allowing sources flexibility to reduce their emissions in the most cost-effective manner consistent with the statute. However, North Carolina expressed concerns about a regional trading program that could operate to deprive North Carolina of the benefits of the control remedy in the subset of States that affect North Carolina (Petition, pp. 25-28). We address this issue below in section VI. 3. What Is the Technical Support for the Petition?

   To support its claim that EGUs outside North Carolina are contributing significantly to nonattainment and maintenance problems in the State, North Carolina relies largely on EPA's technical analyses for the proposed CAIR. Therefore, as discussed above, the petition targets sources in the same States that EPA linked to North Carolina in the proposed CAIR. As additional support, North Carolina cites analyses conducted by the Southern Appalachian Mountains Initiative (SAMI) on PM2.5transport, North Carolina's further evaluation of the SAMI's analyses, as well as back trajectory analyses performed by the North Carolina Division of Air Quality from PM2.5monitors in two counties. (See Petition, pp. 13-17.)

5. What Is the Litigation on the Section 126 Rulemaking Schedule?

   On March 19, 2004, EPA received a petition from the State of North Carolina filed under CAA section 126. Section 126(b) requires EPA to make the requested finding, or to deny the petition, within 60 days of receipt. It also requires EPA to provide a public hearing before acting on the petition. In addition, EPA's action under section 126 is subject to the procedural requirements of section 307(d) of the CAA. (See section 307(d)(2)-(5).) One of these requirements is that EPA conduct notice-and-comment rulemaking. Section 307(d)(10) provides for a time extension, under certain circumstances, for rulemakings subject to that provision. Specifically, it allows statutory deadlines that require promulgation in less than 6 months from proposal to be extended to not more than 6 months from proposal to afford the public and the Agency adequate opportunity to carry out the purposes of section 307(d). In an action published on May 26, 2004 (69 FR 30038), EPA extended the deadline for EPA to take action on the North Carolina petition by the full 6 months, to November 18, 2004.

   On February 17, 2005, the State of North Carolina and the citizen group Environmental Defense filed complaints against EPA seeking to compel EPA to take action on the State's section 126 petition: State of North Carolina v. Johnson, No. 5:05-CV-112 (E.D. N.C.) and Environmental Defense v. Johnson, No. 5:05-CV-113 (E.D.N.C.). The EPA, North Carolina, and Environmental Defense filed a proposed consent decree that would establish a schedule for EPA to act on the petitions. Pursuant to CAA section 113(g), the EPA solicited comments on the proposed consent decree, by notice dated March 2, 2005 (70 FR 10089). The comment period closed April 1, 2005 without EPA receiving negative comment. On May 9, 2005, the court entered a slightly modified version of the consent decree.

   The schedule in the consent decree requires that no later than August 1, 2005, EPA must sign for publication the proposed action to grant or deny the petition. If EPA proposes to approve any part of the petition, the proposal must include the proposed remedy. No later than March 15, 2006, EPA must take final action to grant or deny the petition. If EPA grants any part of the petition (i.e., makes a section 126(b) finding), the final action must include the remedy. The consent decree also requires EPA to hold a public hearing on the proposal during the week of September 12, 2005 in North Carolina. Today's proposal meets the first deadline set forth in the consent decree. The EPA has scheduled two public hearings during the week of September 12, 2005, one to be held in

   [[Page 49716]]

   North Carolina and the other in Virginia (see DATES above for further information on the hearings).

6. How Is EPA Addressing the Section 126-Related Comments Received During the CAIR Rulemaking?

   In the January 30, 2004 CAIR proposal, EPA set forth its general view of the approach it expected to take in responding to any section 126 petition that might be submitted that relies on essentially the same record as the CAIR (69 FR at 4580). That approach is the one EPA used in addressing section 126 petitions that were submitted to EPA in 1997 while EPA was developing the NOXSIP Call to control ozone transport (as discussed in section I.C.3. above).

   The EPA received comments on the CAIR proposal regarding its intended approach for acting on any future section 126 petitions that might be filed. Many commenters expressed support for the approach that EPA had outlined. Other commenters raised issues regarding the timing of emissions reductions under a new section 126 action. Some pointed out that the CAIR compliance date would be later than the 3 years allowed for compliance under section 126. Some were concerned that the proposed CAIR compliance date was later than many attainment dates and, therefore, States may need section 126 petitions in order to get earlier upwind reductions in order to meet their attainment dates. Some questioned the legal basis for linking the two rules. Several commenters expressed concern that EPA would be restricting the use of or weakening the section 126 authority. A number of commenters urged EPA not to prejudge any petition, but to evaluate each on its own merit. Some thought that any petitions submitted prior to designations or before States had had the opportunity to prepare SIPs would be premature and should be denied. Others suggested that the CAIR might not solve all the transport problems and that States would need to retain the section 126 tool to seek further reductions.

   As discussed above, after issuing the CAIR proposal, EPA received, on March 19, 2004, the section 126 petition from North Carolina. In the final CAIR, we stated that when we propose action on the North Carolina petition, we would set forth our view of the interaction between section 110(a)(2)(D) and section 126 . Section II below explains EPA's view of this interaction.

   In addition, we said we would take into consideration and respond to the section 126-related comments we received on the CAIR. The EPA has reviewed all the comments and will be providing responses to the relevant ones in the docket for this rulemaking action.

   II. What Is EPA's Legal and Analytical Approach for the Section 126 Petition?

   As described in section I.C.2 above, section 126 of the CAA is integrally related to the CAA's ``good neighbor'' provision, section 110(a)(2)(D), which requires States to adopt implementation plans to prohibit emissions from sources within the State that significantly contribute to other States' nonattainment of a NAAQS, or which interfere with other States' ability to maintain a NAAQS. Under section 126, a downwind State ``may petition the Administrator for a finding that any major source or group of stationary sources emits or would emit any air pollutant in violation of CAA section 110(a)(2)(D).'' Should EPA make a finding that a source or group of sources is emitting in violation of the section 110(a)(2)(D) prohibition, existing sources in violation may operate no longer than 3 months unless the sources comply with emission limitations and compliance schedules provided by the Administrator which bring about compliance ``as expeditiously as practicable, but in no case later than three years after the date of such finding.'' See section 126(c).

   The EPA's determination whether or not to grant a section 126 petition consequently turns on whether SIPs are in violation of section 110(a)(2)(D). See Appalachian Power v. EPA, 249 F. 3d 1032, 1045-46 (DC Cir., 2001), holding that the determination of whether the ``prohibition'' on excessive interstate transport of air pollutants is being violated is the same under section 110(a)(2)(D) and section 126; see also North Carolina Petition p. 22 (``the operative legal standard under sections 110 and 126 is identical''). Moreover, because of this interrelation and identity, EPA has construed section 126 as applying on a statewide contribution basis when dealing with issues of interstate transport of ozone precursors. This means that a finding by EPA that a SIP is in violation of section 110(a)(2)(D)(i) is a sufficient basis for a finding that sources within that State are in violation of that prohibition for purposes of section 126(b) (64 FR at 28282). No more individualized determination for a source or group of sources is necessary. Id. This is because sources' contribution to nonattainment is collective, so that even relatively small individual contributions are significant in the aggregate. Id. Thus, ``[i]f State- wide emissions contribute significantly to nonattainment downwind, then the State's section 126 sources may be subject to SIP controls; if State-wide emissions do not contribute significantly, then the State's section 126 sources would not be subject to SIP control.'' Id.; see Appalachian Power, 249 F. 3d 1049-50 (upholding this determination). Under this approach, therefore, if EPA determines that a State's SIP fails to meet the requirements of section 110(a)(2)(D)(i) with respect to a downwind State, it follows that the prohibition in section 126 is also violated with respect to that downwind State.

   In the CAIR, EPA defined ``significant contribution'' as consisting of an air quality factor reflecting an upwind State's ambient impact on downwind nonattainment areas, and the cost-factor of availability of highly cost-effective controls (70 FR at 25174). The reductions required are expressed as Statewide budgets of PM2.5and ozone precursors (SO2and NOXfor PM2.5, and NOXfor ozone) susceptible to reduction by highly cost effective controls. For PM2.5, an upwind State must contribute at least 0.2 [mu]g/m3 PM2.5to at least one downwind nonattainment area (the ``link'') to satisfy the air quality part of the test. Id. at 25191. For ozone, the air quality component is satisfied if the maximum contribution by an upwind State is at least 2 parts per billion, the average contribution is greater than one percent, and certain other numerical criteria are met. Id. at 25175. The CAIR rule also stated that an upwind State's emissions can interfere significantly with a downwind State's maintenance of a NAAQS when EPA, or a State, can reasonably project based on available data that in the absence of CAIR controls, a current or projected nonattainment area will revert to nonattainment, after having achieved attainment, due to continued emissions growth or to other relevant factors. Id. at 25193; see also the response to comments document for the CAIR, section III.C.17, docket number OAR-2003-0053-2165.

   The EPA is adopting this same approach in the present rulemaking. This, of course, is a consequence of EPA's interpretation (just explained) that a violation of 110(a)(2)(D)(i) also indicates that sources are emitting in violation of the section 110(a)(2)(D) prohibition for purposes of section 126(b). For the same reason, EPA is adopting the highly cost-effective component of the test from the CAIR rule, with the consequent emission budgets.

   Once EPA finds under section 126(b) that a source (or sources) is operating in violation of the section 110(a)(2)(D)(i)

   [[Page 49717]]

   prohibition, the violation would be eliminated (assuming that sources continue to operate) by EPA approving a SIP containing provisions eliminating the significant contribution, or by EPA itself adopting a FIP which contains provisions eliminating that contribution, by the deadline for the section 126 sources. This means that a section 126(b) violation no longer exists once EPA approves a timely SIP, or adopts a timely FIP, requiring each State contributing significantly (in this case, to North Carolina) to reduce emissions to the levels reflecting elimination of the State's significant contribution, as specified in the CAIR. This result is again a consequence of the integral relationship of section 126(b) and section 110(a)(2)(D).

   The EPA intends to apply these same principles in responding to future section 126 petitions from States in the CAIR region addressing CAIR pollutants. Thus, we would deny these petitions with respect to any State having an approved SIP meeting the CAIR emissions reductions requirements and with respect to States for which EPA has promulgated a CAIR FIP. In such a case there would be no underlying section 110(a)(2)(D) violation, and such a violation is the predicate for granting a section 126 petition.

   III. What Is EPA's Proposed Action on the Section 126 Petition?

   As discussed in the preceding section, EPA is proposing to rely on the conclusions drawn in the final CAIR in determining whether emissions from sources in the States named in the petition contribute significantly to 8-hour ozone and/or PM2.5nonattainment and maintenance problems in North Carolina. As discussed in section I above, North Carolina based its petition in large part on the analyses for the proposed CAIR--identifying EGUs in the same upwind States that EPA proposed to link to North Carolina. The EPA conducted new modeling analyses using updated emissions inventories for the final CAIR. The EPA also applied a different value for the threshold contribution level for the air quality portion of the significant contribution determination for PM2.5in the final CAIR. Therefore, the upwind State-to-downwind State linkages differed in the final CAIR from the proposal.

1. What Is EPA's Proposed Action With Respect to the 8-Hour Ozone NAAQS?

   In its petition, North Carolina requested that EPA make findings that large EGUs in Georgia, Maryland, South Carolina, Tennessee, and Virginia contribute significantly to nonattainment in, or interfere with maintenance by, North Carolina with respect to the 8-hour ozone NAAQS. In the proposed CAIR, EPA linked these States to 8-hour ozone air quality problems in Mecklenburg County, North Carolina. In the final CAIR, EPA's updated analyses project all of North Carolina to be in attainment for 8-hour ozone in the CAIR 2010 base case. Therefore, EPA did not link any upwind States to North Carolina with respect to the 8-hour ozone NAAQS in the final CAIR (See preamble Table VI-9; 70 FR at 25249). Consequently, EPA is proposing to deny the section 126 petition with respect to the 8-hour ozone NAAQS.

2. What Is EPA's Proposed Action With Respect to the PM2.5 NAAQS?

   In its petition, North Carolina also requested that EPA make findings that large EGUs in Alabama, Georgia, Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia and West Virginia contribute significantly to nonattainment in, or interfere with maintenance by, North Carolina with respect to the PM2.5NAAQS. In the proposed CAIR, these 12 States were linked to PM2.5nonattainment problems in North Carolina. In the final CAIR, as noted, EPA used different, updated modeling and also applied a 0.2 [mu]g/m3contribution threshold level rather than the proposed 0.15 [mu]g/m3for the air quality portion of the significant contribution determination (70 FR 25190-25191). Based on the updated modeling and the 0.2 [mu]g/m3 contribution threshold level, EPA determined in CAIR that the following 10 States are significantly contributing to PM2.5air quality problems in North Carolina: Alabama, Georgia, Indiana, Kentucky, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, and West Virginia (see preamble Table VI-8; 70 FR at 25248-25249). As explained in section II above, under the collective contribution approach, this means for purposes of section 126(b) that sources within these States for which EPA determined highly cost-effective controls are available are also contributing significantly to PM2.5 nonattainment problems in North Carolina.

   In determining what action to propose in response to the PM2.5portion of the section 126 petition, EPA is taking into consideration the FIP that is being proposed today in conjunction with this section 126 action (see section IV below). The FIP proposes control requirements for each of the States affected by the CAIR in order to achieve the emissions reductions required to address interstate transport. The EPA plans to issue the final FIP at the same time as the final section 126 action. Therefore, for EGUs in States linked to North Carolina in CAIR (and therefore, for which EPA is proposing a FIP), EPA is proposing in the alternative (1) to deny the petition if EPA issues the final FIP to address the interstate transport no later than the final section 126 response or (2) to grant the petition and make section 126 findings if EPA does not promulgate the FIP prior to or concurrently with the final section 126 response. Because the FIP would fully address the PM2.5-related interstate transport problem identified in CAIR and thus eliminate the section 110(a)(2)(D) violation, there would no longer be a basis for the section 126 findings. As discussed in section VI, we are proposing the Federal CAIR NOXand SO2cap and trade programs as the control remedy for both the section 126 action and the FIP. Therefore, whether the upwind sources in these 10 States are regulated under the section 126 action or the FIP, the emissions reductions requirements and compliance deadlines would be the same.

   For EGUs located in Illinois and Michigan, which are not linked to North Carolina in the final CAIR with respect to the PM2.5 NAAQS (70 FR 25247-48), EPA is proposing to deny the petition.

   The EPA notes that it is not including any regulatory text for the proposed findings because EPA's preferred alternative is to promulgate the CAIR FIP and fully deny the North Carolina section 126 petition.

3. What Are the Proposed Requirements for Sources for Which EPA Makes a Section 126(b) Finding?

   The EPA is proposing, in sections V and VI below, NOX and SO2Federal cap and trade programs that would apply to any new or existing EGU for which EPA ultimately makes a section 126(b) finding in response to the North Carolina petition. The proposed Federal cap and trade programs are largely the same as the model trading rules for EGUs that EPA provided in the CAIR as control options for States, although EPA is proposing certain differences that are primarily intended to account for Federal implementation and to facilitate transfer from the proposed Federal programs to State programs. (See section VI for a description of the differences). The same EGU budgets and compliance dates would apply.

   As in the CAIR, the NOXand SO2reductions would occur in two phases.

   [[Page 49718]]

   The first phase of NOXreductions would start in 2009 (covering 2009-2014) and the first phase of SO2reductions would start in 2010 (covering 2010-2014); the second phase of reductions for both NOXand SO2would start in 2015 (covering 2015 and thereafter).

   Section 126(c) states, in relevant part, that: it shall be a violation of this section and the applicable implementation plan in such State

   (1) For any major proposed new (or modified) source with respect to which a finding has been made under subsection (b) to be constructed or to operate in violation of this section and the prohibition of section 110(a)(2)(D)([i]) or this section, or

   (2) For any major existing source to operate more than three months after such finding has been made with respect to it.

   The Administrator may permit the continued operation of a source referred to in paragraph (2) beyond the expiration of such three-month period if such source complies with such emission limitations and compliance schedules (containing increments of progress) as may be provided by the Administrator to bring about compliance with the requirements contained in section 110(a)(2)(D)([i]) as expeditiously as practicable, but not later than three years after the date of such finding.

   The Federal cap and trade programs that EPA is proposing would satisfy the section 126 requirements. The control requirements would ensure that the sources do not emit in violation of the section 110(a)(2)(D)(i) prohibition and would serve as the alternative set of requirements that the Administrator may apply for the purpose of allowing existing sources subject to a section 126(b) finding to operate for more than 3 months after the finding is made.

   Under the consent decree, described in section I above, EPA must sign the final action on the petition by March 15, 2006. If EPA makes any findings at that time, and they become effective 60 days later, consistent with section 126(c), compliance with the control remedy must be required no later than May 14, 2009. The control remedy that EPA is proposing would satisfy the 3-year compliance period in section 126(c). First, the remedy would commence within the 3-year maximum timeframe set out in section 126(c), since as just explained, the phase I NOXcontrol requirements would take effect on January 1, 2009. Further controls on SO2and NOXwould be required as soon as technically feasible. The EPA views the proposed NOXand SO2emissions reduction requirements as a single action, but one that cannot be fully implemented in 2009 and instead must be implemented in phases solely for reasons of feasibility. In analyses conducted for the CAIR, EPA determined that part of the NOXand SO2emissions reductions cannot feasibly be implemented until 2015 and the first phase of SO2emission reductions cannot feasibly be implemented until 2010. In this regard, we note that section 126(c) on its face contemplates that control measures satisfying both section 126 and section 110(a)(2)(D) may stretch out beyond a 3-year period. Section 126(c) states that sources that are subject to a section 126(b) finding may continue to operate if they comply with ``emissions limitations and compliance schedules (containing increments of progress) provided by

   [EPA] '' (emphasis added); the reference to increments of progress can describe a situation where compliance is stretched out over periods exceeding 3 years provided initial action (i.e., an initial increment of progress) occurs within 3 years. See also North Carolina Petition at pp. 28-29 supporting a phased approach to compliance and noting that a stepwise approach to regional emissions reductions is ``consistent with the requirement that a section 126 remedy `contain[] increments of progress * * *' '' Section VII of this preamble describes the proposed section 126 control requirements in greater detail.

4. When and How Would EPA Withdraw Section 126 Findings and Control Requirements in a State if EPA Approves a SIP To Meet the CAIR?

   Under today's proposal, by March 15, 2006, EPA would take final action to either make section 126 findings for sources in 10 States contributing significantly to North Carolina's nonattainment and maintenance problems for the PM2.5NAAQS or promulgate a FIP for all CAIR States for the PM2.5and/or 8-hour ozone NAAQS. The CAIR requires States to submit SIP revisions by September 11, 2006. Therefore, the Federal CAIR trading programs would be promulgated in advance of the SIP submission deadline. As stated previously, the section 126 response and FIP would not limit the options available to States to meet the requirements of CAIR. The EPA intends to withdraw the section 126 or the FIP requirements in a State in coordination with approval of an implementation plan for the State that meets the CAIR requirements. In the timing of the SIP approval, EPA would take into consideration whether the SIP approval would occur before or after EPA has begun recording allowances in source accounts under Federal CAIR trading programs.

   It is EPA's preference that States regulate sources to control the interstate transport, including making decisions regarding NOXallocations, should a State choose to participate in the State CAIR trading programs. Consequently, EPA does not intend to record NOXallocations in sources' allowance accounts (or take any other steps to implement the section 126 or FIP requirements that could impact a State's ability to regulate their sources in a different manner) until December 1, 2007, more than a year after the CAIR SIP submission deadline.\6\ This would allow EPA time to take rulemaking action to approve timely, compliant SIPs and withdraw the section 126 or FIP requirements.

   \6\ The CAIR requires affected sources to begin monitoring 1 year before the initial control periods (i.e., sources begin monitoring in 2008 for the NOXprograms and begin monitoring in 2009 for the SO2program). Note that EPA would take any necessary actions to implement the monitoring provisions of the proposed Federal trading rules in time for monitoring to begin in 2008. To the extent that a State chooses to control EGUs to meet its CAIR obligations, the monitoring requirements would be identical whether EPA regulated EGUs through the proposed Federal trading programs or the State regulated EGUs through their SIP.

   If a SIP is approved that includes the EPA-administered State CAIR trading programs after EPA has recorded allowances for the Federal CAIR trading programs, EPA would work with the State to ensure a smooth transition from the Federal trading programs to the State trading programs. To preserve the integrity of the trading program budgets, once Federal allocations are recorded in source accounts for a particular control period, EPA does not intend to approve overlapping State allocations for the same control period. Rather, EPA will work with the States to approve State allocations for control periods that begin upon the expiration of a control period for which Federal allocations have been recorded in source accounts.

   In section VI below, EPA proposes the schedule for recording Federal NOXallocations in source accounts. Under this schedule, EPA seeks to balance two goals: (1) To provide adequate time for States to submit and for EPA to approve SIPs containing the NOXallocations, and (2) to provide certainty to sources regarding their CAIR NOXallocations in adequate time for sources to make compliance decisions. Under this schedule, EPA would record the allowances 1 year at a time for the first two control periods. Thus, for SIPs approved after EPA has recorded the 2009 allocations on December 1, 2007, but before EPA has recorded the 2010

   [[Page 49719]]

   allocations on December 1, 2008, EPA would time the withdrawal of the FIP or section 126 requirements such that allocations would be made under the State CAIR trading program for the 2010 control period. There would be another opportunity for transitioning from the Federal to State trading programs for the 2011 control period. As discussed in section VI below, EPA is proposing to record NOXallowances in source accounts by December 1, 2009 for the 2011-2013 control periods. Therefore, for SIPs approved after December 1, 2009, the transition from the Federal to State program would not occur until the 2014 control period. The EPA believes it is unlikely that there would be any outstanding SIPs to be approved after December 1, 2009. The EPA intends to work with States to help ensure that NOX allowances can be allocated under the State CAIR trading programs beginning with the initial 2009 control period. In order to expedite the approval of the SIP allowance allocation methodology and provide additional flexibility to States, EPA is proposing an abbreviated SIP option as discussed in section VI. See section VI for a detailed discussion of EPA's proposed schedule for recording Federal NOXallocations in source allowance accounts.

   For States that choose to implement the CAIR requirements using a method other than the EPA-administered State CAIR trading programs, the EPA would also carefully consider the timing of the transition from the Federal trading programs to the State-implemented programs to avoid disruption of the Federal trading programs within any annual or ozone season control period.

   IV. What Is the Proposed Federal Implementation Plan for the CAIR?

1. What Is the Legal Framework for the Proposed FIP?

   Section 110(c)(1) of the CAA requires the Administrator to promulgate a Federal Implementation Plan (FIP) within 2 years of: (1) Finding that a State has failed to make a required submittal, (2) finding that a submittal received does not satisfy the minimum completeness criteria established under section 110(k)(1)(A), or (3) disapproving a SIP submittal in whole or in part. The EPA may issue a FIP any time after making one of these findings or issuing a SIP disapproval and it must do so within 2 years. However, EPA is relieved of this obligation if a SIP revision correcting the deficiency identified is approved by EPA before such a FIP is promulgated.

   As discussed in paragraph I.D.5, in a final rule signed the same day as CAIR, EPA found that States have failed to submit SIPs to satisfy the interstate transport requirement under section 110(a)(2)(D)(i) of the CAA for the PM2.5and 8-hour ozone NAAQS (70 FR 21147). These findings started the 2-year clock for the promulgation of a FIP. They did not start a ``sanctions clock'' as there are no mandatory sanctions associated with the FIP or the finding of State failure to submit SIPs to satisfy 110(a)(2)(D)(i).

   The EPA has broad authority to act when it has identified deficiencies in SIPs. This authority is of three general types. First, EPA may promulgate any measure which it is permitted to issue pursuant to pre-existing independent statutory authority--for example, the provisions of title II. That is, EPA may promulgate any measure which it has authority to issue in a non-FIP context, without reliance on section 110(c). Second, EPA may invoke section 110(c)'s general FIP authority and act to cure a SIP deficiency in any way not clearly prohibited by statute. Third, under section 110(c), the courts have held that EPA may exercise all authority that the State may exercise under the CAA.

   The first type of authority, EPA's general authority is independent of section 110(c). It is not dependent on or altered by finding a deficiency in a SIP.

   The second type of authority, EPA's general authority under section 110(c), is essentially remedial. The EPA has broad power under that section to cure a defective State plan. Thus, in promulgating a FIP, EPA may exercise its own, independent regulatory authority under the CAA in any way not clearly prohibited by an explicit provision of the CAA. When EPA has promulgated a FIP, courts have not required explicit authority for specific measures: ``We are inclined to construe Congress' broad grant of power to the EPA as including all enforcement devices reasonably necessary to the achievement and maintenance of the goals established by the legislation.'' (South Terminal Corp. v. EPA, 504 F.2d 646, 669. (1st Cir., 1974)). See also City of Santa Rosa v. EPA, 534 F.2d 150, 153-154 (9th Cir., 1976) (upholding the Administrator's authority to promulgate a FIP imposing gas-rationing in Los Angeles on a massive scale). ``The authority to regulate pollution carries with it the power to do so in a manner reasonably calculated to reach that end.'' Id. at 155.

   In addition, when EPA has determined that a State has not completely discharged its primary responsibility to protect its air quality, EPA is compelled to assume this task and thus the powers of the defaulting State accrue to EPA. As the Ninth Circuit has held, when EPA acts in place of the State pursuant to a FIP under section 110(c), EPA ``stands in the shoes of the defaulting State, and all of the rights and duties that would otherwise fall to the State accrue instead to EPA,'' Central Arizona Water Conservation District v. EPA, 990 F.2d 1531, at 1541 9th Cir., 1993). The First Circuit, in an early FIP case, agreed:

   The Administrator must promulgate promptly regulations setting forth an implementation plan for a State should the State itself fail to propose a satisfactory one. The statutory scheme would be unworkable were it read as giving to EPA when promulgating an implementation plan for a State, less than those necessary measures allowed by Congress to a State to accomplish Federal clean air goals. We do not adopt any such crippling interpretation.

   South Terminal Corporation v. EPA, 504 F.2d 668 (1st Cir., 1974).

   In the case of federally-recognized Indian Tribes, as we explained in the CAIR, (70 FR 25167-68) Tribes are subject to section 110(a)(2)(D), but are not required to submit implementation plans. The EPA is required to promulgate FIPs for Indian country as necessary or appropriate to protect air quality. See 40 CFR 49.11(a). Presently, there are no emissions sources in Indian country within the region affected by CAIR which would make a FIP necessary or appropriate. In the event of the planned construction of such a source within Indian country in the 28-State region subject to CAIR, EPA will work with the relevant Tribal government to regulate the source through a Tribal or Federal implementation plan. In the case of an EGU, the EPA anticipates that the Tribal implementation plan (TIP) or FIP would involve the participation of the EGU in the EPA administered cap and trade program. The EPA will also work with the Tribe and affected States to determine how allowances allocated to the Indian country source will affect State allowance allocations. Because any FIPs for Indian country will necessarily be tailored to the specific circumstances, today's proposal contains no such FIP. The reader is referred to the CAIR for a more detailed discussion of the interaction of the CAIR with Indian country (70 FR 25167-68, 25315).

2. What Is the Timing and Scope of the CAIR FIP Action?

   As described in the CAIR, EPA views seriously its responsibility to address the issue of regional transport of ozone and ozone precursor emissions.

   [[Page 49720]]

   Decreases in NOXand SO2emissions are needed in the States identified in the CAIR to enable downwind States to develop and implement plans to achieve and maintain the PM2.5and 8- hour ozone NAAQS. The CAIR identified the specific amount of emissions reductions necessary for each State identified in the CAIR to meet their section 110(a)(2)(D) interstate transport obligations. Implementation of these reductions is necessary to enable downwind States to achieve the NAAQS in order to provide clean air for their residents.

   Therefore, EPA is proposing FIPs today in conjunction with the proposed action regarding North Carolina's section 126 petition concerning transport of PM2.5and 8-hour ozone precursors as discussed in section III of this proposal. The EPA intends to promulgate these FIPs at the same time as its response to North Carolina's section 126 petition, which must be finalized no later than March 15, 2006 in accordance with a judicially enforceable consent decree. The EPA believes it is appropriate to coordinate these two rulemakings because they both address interstate transport, both will apply to EGUs, and because the States covered by the response to the section 126 petition are a geographical subset of the States covered by CAIR. In today's action, EPA is not proposing to promulgate FIPs for any States not covered by CAIR.

   The EPA believes it is appropriate to finalize the FIP in March 2006 on the same schedule as EPA's response to the section 126 petition. Moving quickly to promulgate a FIP is consistent with Congress' intent that attainment occur in these downwind nonattainment areas ``as expeditiously as practicable'' (sections 181(a), 172(a)). The FIP will help ensure that all emissions reductions required by CAIR, and the associated environmental benefits, will be achieved by the CAIR deadlines. In addition, the FIP will ensure that sources in all States covered by CAIR, regardless of whether they are affected by the North Carolina section 126 petition, will be required to achieve emissions reductions at the same time.

   By proposing and finalizing the FIP well before the deadline for States to submit their CAIR SIPs, EPA is providing States an additional option for complying with the requirements of CAIR. States planning to adopt the model trading programs contained in the CAIR rule, could accept the FIP and significantly reduce the State resources needed to establish a program to implement the CAIR. Since there are no punitive consequences for States associated with the FIP or the finding of failure to submit SIPs to satisfy section 110(a)(2)(D)(i), some States could avoid much of the time and expense of revising their SIPs to comply with CAIR. Some States, particularly those subject to the NOXSIP Call, may need to prepare minor SIP revisions regardless of whether they accept the FIP implementing the requirements of CAIR; yet the time and expense involved would be significantly reduced.

   The Agency proposes to provide States that are subject to today's proposed Federal requirements with the option to submit abbreviated SIP revisions covering specific elements of the Federal trading programs without submitting full SIP revisions to meet the requirements of CAIR. By proposing to accept such abbreviated SIP revisions, the Agency intends to increase the options available for States to comply with CAIR. A State could choose to retain control of these specific elements of the trading programs, without submitting a full SIP revision to meet the requirements of CAIR. As there are no sanctions associated with the proposed FIP, EPA anticipates that some States may prefer to avoid spending the time and money necessary to submit a full SIP revision.

   The Agency would accept abbreviated SIP revisions for any or all of the following 4 specific elements of the Federal trading programs: (1) Provisions for non-EGUs to opt-in to the Federal trading programs, (2) allocating annual and/or ozone season NOXallowances to individual sources in the State, (3) allocating allowances from the annual NOXCompliance Supplement Pool (CSP) to individual sources in the State, and (4) including NOXSIP Call trading sources that are not EGUs under CAIR in the Federal CAIR ozone season NOXcap and trade program. Upon approval of any such SIP revisions, EPA anticipates that the corresponding portions of the FIP for that State would be replaced or their application to sources would be modified.

   In offering a framework for abbreviated SIP revisions the Agency anticipates that many States will wish to retain control over the allocation of allowances to sources in their State and may wish to meet their NOXSIP Call obligations by allowing NOX budget units (that is, units in the NOXSIP Call trading program) that are not EGUs under CAIR to participate in the CAIR ozone season trading program.

   The EPA requests comment on the proposed option for States to submit abbreviated SIPs covering specific elements of the Federal trading programs. A more complete discussion of the proposed abbreviated SIP provisions is found in Section VI.

   Thus, the FIP will increase the options available for a State to comply with CAIR. Through the CAIR rulemaking actions, EPA has provided States with a great deal of data and analyses concerning air quality and control costs, as well as a determination whether upwind sources contribute significantly to downwind nonattainment under section 110(a)(2)(D). The EPA recognizes that States would face great difficulties in developing transport SIPs to meet the requirements of section 110(a)(2)(D) without these data and policies. Indeed, EPA acknowledged in the CAIR that the Agency's extensive analyses and data, including the multi-year operation of a federally-funded monitoring system (and the considerable information generated through that system) was a necessary element in the Agency's conclusion that it was appropriate to impose such requirements on States (70 FR 25267).

   States have 18 months from the signature date of the CAIR, or until September 11, 2006, to develop, adopt, and submit revisions to their SIPs that meet the requirements of CAIR. We remain ready to work with the States to develop fully approvable SIPs. The FIP will not be promulgated for any State that has an approved SIP implementing the CAIR requirements in place prior to promulgation of the FIP. In addition, EPA will withdraw the FIP for any State once EPA approves a SIP that meets the CAIR requirements in that State.

   Having the FIP in place early will provide for a transition to a CAIR trading program with the greatest continuity, administrative ease, and cost savings for States that would otherwise develop a program identical to the model trading program. The EPA's goal is to have approvable programs in place that meet the requirements of the CAIR whether they are in the form of a SIP or a FIP. By finalizing a FIP, EPA would in no way preclude a State from developing its own SIP to either adopt the trading rule with any discretionary elements allowed by the CAIR, or to meeting the State emissions budget through different measures of the State's choosing. The EPA will carefully consider the timing of each element of the FIP process to make sure to preserve each State's freedom to develop and implement SIPs. In this way, EPA will enhance each State's options for complying with the requirements of the CAIR while ensuring that all the emissions reductions and environmental benefits of the CAIR are realized.

   [[Page 49721]]

3. What Are the FIP Control Measures?

   In contrast to the SIP process--where selection and implementation of control measures is the primary responsibility of the State--in the case of a FIP, it is EPA's responsibility to select the control measures for sources and assure compliance with those measures. Thus, while the FIP would be designed by EPA to achieve the same total emissions reductions described in the CAIR, the specific control measures assigned in the FIP could be different from what a State might choose.

   In selecting the control measures for the FIP, EPA is proposing the same measures used in the CAIR for calculating the required emissions reductions. In the CAIR, EPA is requiring States to achieve specified levels of emissions reductions based on levels that are achievable through implementation of highly cost-effective controls on EGUs. See the discussion in section IV of the CAIR, ``What Amounts of SO2and NOXEmissions Did EPA Determine Should Be Reduced?'' The EPA is including by reference the technical basis and supporting rationale for EPA's conclusions as to the highly cost- effective strategy developed for the CAIR.

   The SO2and NOXcap and trade programs for the FIP are discussed below in section VI. The unit allocations will be provided in a later action and will meet the State EGU budgets that are established in the CAIR for States that choose to meet the required emissions reductions by controlling EGUs only.

4. When and How Would EPA Remove the FIP Requirements if EPA Approves a SIP To Meet the CAIR?

   As discussed previously, EPA intends to finalize the FIP by March 15, 2006, concurrently with EPA's response to the section 126 petition from North Carolina. The EPA intends to withdraw the FIP in a State in coordination with EPA's approval of a SIP for that State that meets the CAIR requirements. It is EPA's preference that States regulate sources to control the interstate transport, therefore EPA will work with States to help ensure that the FIP would not need to be implemented. The EPA's intended process for withdrawing the FIP or section 126 requirements is discussed above under section III.D.

   V. Emission Reduction Requirements for the Proposed CAIR FIP and Proposed Section 126 Response

1. Overview of Emission Reduction Requirements

   In the CAIR (70 FR 25162), EPA determined that SO2and NOXemissions from sources in the District of Columbia and the following 23 States contribute significantly to downwind PM2.5nonattainment: Alabama, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Mississippi, Missouri, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas, Virginia, West Virginia, and Wisconsin.

   In the CAIR, the Agency also determined that the District of Columbia and the following 25 States contribute significantly to downwind 8-hour ozone nonattainment: Alabama, Arkansas, Connecticut, Delaware, Florida, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Virginia, West Virginia, and Wisconsin.

   The EPA established CAIR annual SO2and NOX emission reduction requirements for States that contribute significantly to downwind PM2.5nonattainment and established ozone season NOXemission reduction requirements for States that contribute significantly to downwind 8-hour ozone nonattainment. The CAIR requires upwind States to revise their State implementation plans (SIP) to include control measures to reduce emissions of SO2and/or NOXto meet the requirements in CAIR (SO2is a precursor to PM2.5 formation, and NOXis a precursor to both ozone and PM2.5formation).

   The CAIR requires that the emission reductions be implemented in two phases. The first phase of CAIR NOXreductions starts in 2009 (covering 2009-2014) and the first phase of CAIR SO2 reductions starts in 2010 (covering 2010-2014); the second phase of CAIR reductions for both NOXand SO2starts in 2015, covering 2015 and thereafter.

   The EPA determined the required amounts of CAIR emission reductions based on the application of highly cost-effective controls on electric generating units (EGUs). The States have flexibility in how to achieve the CAIR emission reductions.\7\ The CAIR includes model rules for regionwide EGU emission cap and trade programs, which States can choose to adopt to obtain the required reductions in a flexible and cost- effective manner (the CAIR SIP model trading rules).

   \7\ The amounts of State-by-State emission reductions required by CAIR are determined based on State EGU emission budgets. Determination of a State's emission reduction requirements depends on the source categories that the State chooses to control and, if the State controls only EGUs, on whether it chooses to participate in the EPA-administered EGU emissions cap and trade programs. See section V in the CAIR NFR preamble (70 FR 25229) as well as the technical support document entitled ``Regional and State SO2and NOXEmissions Budgets,'' March 2005, for detailed discussion of the relationship between CAIR EGU emissions budgets and the State emission reduction requirements. Also see Sec. 51.123 and Sec. 51.124 (70 FR 25319-25333).

   Today, EPA is proposing FIPs that are substantively the same as the CAIR SIP model cap and trade programs. The proposed FIPs would achieve the NOXand SO2emission reductions required under the CAIR, by requiring EGUs in the affected States to reduce emissions through participation in Federal CAIR NOXand SO2cap and trade programs. The EPA intends to integrate these Federal trading programs with the model trading programs that States may choose to adopt to meet the CAIR (see section VI.J in this preamble for a discussion of coordination between today's proposed Federal cap and trade programs and CAIR SIP cap and trade programs). The proposed Federal CAIR cap and trade programs would achieve the emission reductions required by CAIR by the deadlines established in that rule, with the same highly cost-effective EGU control measures forming the basis for the emission budgets.

   For States affected by the proposed section 126 remedy (see section III for affected States), the Federal CAIR cap and trade programs would achieve the required emission reductions. As explained in section I of this preamble, for sources in States that the Agency found to be contributing significantly to nonattainment or maintenance in North Carolina under CAIR, the Agency is proposing to deny the petition for sources in any such State if, prior to or concurrently with the final section 126 response, EPA promulgates a FIP to address the interstate transport from that State. The Agency is proposing, in the alternative, to grant the petition. The Agency intends to promulgate FIPs concurrently with the final section 126 response.

   The regionwide emission reduction requirements and State emission budgets that are the basis for today's proposal were established in the CAIR rulemaking. The EPA is not requesting comment on its determination of the CAIR regionwide emission reduction requirements or State emission budgets, nor is the EPA requesting comment on the CAIR regionwide requirements or State budgets themselves.

   On May 12, 2005, the Agency proposed to find that Delaware and New Jersey contribute significantly to downwind PM2.5 nonattainment and

   [[Page 49722]]

   thus proposed to require annual SO2and NOX controls in these two States (70 FR 25408). (In the CAIR NFR, the Agency found Delaware and New Jersey to contribute to downwind 8-hour ozone nonattainment but not to downwind PM2.5 nonattainment). Based on the proposal to require annual SO2 and NOXcontrols in Delaware and New Jersey, today's FIP proposal includes requirements for annual SO2and NOXcontrol in these two States. The EPA determined these required amounts of emission reductions based on the application of highly cost-effective controls on EGUs, and the proposed FIP would achieve these reductions by requiring EGUs to participate in the Federal CAIR cap and trade programs.

   The proposed CAIR FIP would require annual SO2and NOXand ozone season NOXemission reductions (and the proposed section 126 remedy would require annual SO2and NOXreductions) from EGUs in affected States, through participation in regionwide Federal cap and trade programs. The Agency intends the applicability provisions in today's proposal to be identical to the applicability provisions in the CAIR model cap and trade programs. As discussed elsewhere in today's preamble, the Agency is proposing two revisions to the applicability provisions in the CAIR model cap and trade programs. The applicability provisions that EPA is proposing in today's action for the FIP and section 126 remedy would be identical to the applicability provisions in the CAIR model programs if the two proposed revisions to the applicability provisions in the CAIR model programs are finalized. (See section VI.C in today's preamble for a discussion of the proposed applicability provisions for today's action, and see section VII for the proposed revisions to the applicability provisions in the CAIR model programs.)

   In this section, EPA describes the approaches for determining regionwide emission caps and State emission budgets taken in the CAIR rulemaking. In section VI in this preamble, the Agency explains in detail the proposed Federal CAIR cap and trade programs for the CAIR FIP and section 126 response.

   In today's action, the Agency is proposing a federally-administered program to meet the CAIR emission reduction requirements on the timeline established in CAIR. Today's proposal does not establish those emission reduction requirements or schedule, which were established by the CAIR rulemaking. Thus, the Agency is not requesting comment on the emission reduction requirements or the schedule for implementing the emissions reductions.

   The Agency is taking this action to satisfy the concerns of North Carolina cited in its section 126 petition and to provide a Federal backstop for CAIR where all States may not be able to develop and submit timely, approvable SIP revisions. In no way should the FIP for CAIR be viewed as a sign of any concern about States ultimately making the emission reductions required under CAIR. There are no sanctions associated with these FIPs, and EPA does not intend CAIR FIPs to have any other negative consequences for the affected States. To the contrary, EPA is proposing FIP approaches that are flexible and allow States a full opportunity to get their SIP revisions in place, with minimal disruption in transitioning from Federal to State implementation.

2. What Is EPA's Approach for Determining Regionwide NOX and SO2 Emissions Caps and State Emissions Budgets?

   1. Determination of Regionwide Caps for SO2and NOX

   In the preamble to the CAIR NFR, the Agency explained how it determined regionwide SO2and NOXemissions caps. See section IV in the CAIR NFR preamble (70 FR 25195-25229). In determining the amounts of SO2and NOXemissions that must be eliminated for compliance with CAIR, EPA evaluated the amounts of SO2and NOXemissions in upwind States that contribute significantly to downwind PM2.5 nonattainment and the amounts of NOXemissions in upwind states that contribute significantly to downwind 8-hour ozone non- attainment. The EPA determined the amounts of emissions that must be reduced to eliminate significant contributions from upwind States, by applying highly cost-effective control measures to EGUs and determining the emissions reductions that would result (70 FR 25195-25229).

   EPA used the Integrated Planning Model (IPM) to analyze the cost effectiveness of the CAIR emission reduction requirements.\8\ The EPA modeled the cost effectiveness of CAIR assuming interstate emissions trading. While the Agency does not require States to participate in the CAIR SIP regionwide interstate EGU cap and trade programs, we believe it is reasonable to evaluate control costs assuming States choose to participate in such programs since participation will result in less expensive emission reductions. The Agency modeled the CAIR requirements as three regionwide EGU cap and trade programs (an annual SO2program, an annual NOXprogram, and an ozone season NOXprogram). Section IV.A.1 in the CAIR NFR preamble provides more discussion of EPA's cost modeling methodology for the CAIR rulemaking (70 FR 25196-25197). The Agency also evaluated the feasibility of achieving the CAIR emission reduction requirements in the CAIR time-frame, as discussed in section IV.C. in the CAIR NFR preamble (70 FR 25215-25225).

   \8\ The IPM is a multiregional, dynamic, deterministic linear programming model of the U.S. electric power sector. The Agency uses IPM to examine costs and, more broadly, analyze the projected impact of environmental policies on the electric power sector in the 48 contiguous States and the District of Columbia.

   For SO2, the regionwide annual cap for 2015 and later (the second CAIR phase) is based on a 65 percent reduction of title IV Phase II allowances allocated to units in the 23 States and the District of Columbia that are required by CAIR to implement annual SO2controls. The regionwide annual SO2cap for the years 2010-2014 (the first CAIR phase) is based on a 50 percent reduction from those same title IV allocation amounts. The EPA determined these regionwide caps to be highly cost effective by analyzing the cost of controlling emissions from EGUs. Details of EPA's analysis are in section IV in the CAIR NFR preamble (70 FR 25195- 25229).

   Both the annual and the ozone season NOXregionwide caps were determined by applying uniform NOXemission rates to recent historic heat input for EGUs in the affected States (23 States and the District of Columbia for annual NOX, 25 States and the District of Columbia for ozone season NOX). For 2015 and later (the second CAIR phase), the Agency applied an emission rate of 0.125 lb/mmBtu to recent historic heat input. For the years 2009-2014 (the first CAIR phase) the Agency applied an emission rate of 0.15 lb/ mmBtu. The heat input amounts used in these calculations were the highest annual heat input (or ozone season heat input for the ozone season caps) from Acid Rain Program units for any year from 1999 to 2002 for each State. The EPA determined the resulting regionwide caps to be highly cost effective by analyzing the cost of controlling emissions from EGUs. Details of EPA's analysis are in section IV in the CAIR NFR preamble (70 FR 25195-25229).

   [[Page 49723]]

   2. Determination of State by State Emissions Budgets for SO2 and NOX a. Determination of State SO2Emissions Budgets

   In CAIR, the EPA determined State annual SO2emissions budgets for 2015 and later based on a 65 percent reduction from title IV Phase II allowances allocated to units in the affected States and the District of Columbia, and for the years 2010-2014 based on a 50 percent reduction from the title IV allocation amounts. Section V.A.1.a of the CAIR NFR preamble, 70 FR 25229-25230, describes the approach for determining State budgets. The Agency is not inviting comment on the CAIR State SO2budgets. The EPA employed the same approach to determining proposed State SO2budgets for Delaware and New Jersey in its proposal to include these two States in CAIR for annual SO2controls (70 FR 25416).

   Today's proposed FIP and section 126 remedy would achieve the required SO2emission reductions through a regionwide Federal SO2cap and trade program for EGUs. As discussed further in section VI, below, the Federal CAIR SO2cap and trade program would rely on title IV allowances, which sources would retire at specified ratios greater than 1-to-1 for compliance with the proposed Federal CAIR program. Congress has already allocated title IV SO2allowances to sources in perpetuity. State SO2emissions budgets would not affect the distribution of SO2allowances and are not directly relevant for today's proposal.

   The CAIR State SO2budgets were established to provide States flexibility in selecting a control remedy to meet the requirements of CAIR. States can choose to participate in the EPA- administered CAIR SO2trading program, in which case sources would comply by retiring title IV allowances at the specified retirement ratios, and the CAIR State SO2budgets would not be directly relevant. For States that do not choose to participate in the EPA-administered SO2trading program, however, the CAIR State SO2budgets are used to determine the State's emission reduction requirements.\9\ The EPA determined title IV allowance retirement ratios for the CAIR SIP model SO2trading program based on the ratio of the total of all States' CAIR SO2 budgets (for 2010 and 2015) to the total of such States' title IV Phase II allowance levels.

   \9\ See section V in the CAIR NFR preamble (70 FR 25229-25233) as well as the technical support document entitled ``Regional and State SO2and NOXEmissions Budgets,'' March 2005, for detailed discussion of the relationship between CAIR EGU emissions budgets and the State emission reduction requirements. Also see Sec. 51.123 and Sec. 51.124 (70 FR 25319-25333).

   In the CAIR FIP and 126 remedy, the EPA is proposing to use a Federal SO2trading program approach that is substantively identical to the CAIR SIP SO2model trading rule and relies on retirement of title IV allowances at the same specified ratios. Thus, State SO2emission budgets would not affect the distribution of SO2allowances and are not directly relevant for today's proposal.

   For further discussion regarding achieving the required SO2reductions in today's proposed Federal program through retirement ratios for title IV allowances, see section VI in today's preamble. Also see the CAIR NFR preamble in section V.A.1.c (70 FR 25230) as well as section VII (70 FR 25255-25273). b. Determination of State Annual and Ozone Season NOX Emissions Budgets

   In CAIR, EPA determined State annual and ozone season NOXemissions budgets by apportioning the CAIR regionwide annual and ozone season NOXcaps to States based on each State's share of fuel-adjusted average recent historic heat input. For each CAIR State, for each year (1999 through 2002), the Agency summed heat input by fuel type, adjusted the heat input using fuel adjustment factors, and determined the average fuel-adjusted heat input for each State. The fuel adjustment factors that the Agency used to adjust heat input are 1.0 for coal, 0.4 for gas, and 0.6 for oil.

   The EPA summed the average adjusted heat inputs for each State in the CAIR region (either the annual NOXregion or the ozone season NOXregion, as appropriate), and divided each State's average adjusted heat input by the regionwide total average adjusted heat input, to determine each State's proportion of the total. The Agency multiplied each State's proportion by the regionwide caps, to determine each State's proportional share of the regionwide caps. The EPA used the same methodology to determine both annual and ozone season NOXState budgets, except that for annual budgets the annual heat input was used, whereas for ozone season budgets the ozone season heat input was used. (See section V of the CAIR NFR preamble for discussion of the Agency's determination of CAIR State emissions budgets, 70 FR 25229-25233.) The Agency is not inviting comment on the CAIR State annual and ozone season NOXbudgets.

   For its proposal to include Delaware and New Jersey in CAIR for annual NOXcontrols, the Agency proposed to determine annual State NOXbudgets for these two States by first calculating a total ``regional'' cap for the two States, using the same methodology used in CAIR to develop regionwide NOXcaps (the regionwide NOXcap methodology is described above). The EPA proposed to determine State annual NOXbudgets for these two States by apportioning the regional Delaware and New Jersey cap back to the two States using the same fuel-adjusted heat input basis as was used in the CAIR NFR, as described above (also see section IV.B. in the proposal to include Delaware and New Jersey in CAIR for PM2.5purposes, 70 FR 25416).

   In today's proposed Federal CAIR NOXcap and trade programs for EGUs, the State annual and ozone season EGU NOX budgets are the same as the budgets in the CAIR NFR (annual NOXbudgets for Delaware and New Jersey in today's proposal are the same as the annual NOXbudgets for these two States in the proposal to include them in CAIR for PM2.5purposes).

   For each State affected by the proposed Federal CAIR NOX trading programs, the State NOXbudgets are the total amount of allowances \10\ that the Agency will allocate to sources in the State. See section VI in this preamble for EPA's proposed methodology for allocating NOXallowances to affected sources. The EPA's proposed allocation methodology for NOXallowances in the annual NOXand the ozone season NOXcap and trade programs is in contrast with the approach taken in the case of SO2allowances, which are already allocated under title IV of the Clean Air Act to sources in perpetuity, as explained above.

   \10\ As in CAIR, an annual NOXallowance would authorize the emission of a ton of NOXduring a calendar year and an ozone season NOXallowance would authorize the emission of a ton of NOXduring an ozone season. See section VI in this preamble for further discussion and see the proposed regulatory text for definitions.

3. What Are the State EGU Emission Budgets for the CAIR FIP and the Section 126 Response?

   1. What Are the Annual State EGU SO2Emissions Budgets?

   As explained above, the required SO2emission reductions would be achieved solely based on the requirement that sources retire title IV SO2allowances (which were already allocated to sources by Congress) at specified ratios greater than 1-to-1. Because State SO2emission budgets do not affect the distribution of SO2allowances and are

   [[Page 49724]]

   not directly relevant for today's proposal, the Agency is not including State SO2budgets in today's proposal. See section VI in this preamble for discussion of the proposed Federal CAIR SO2trading program. 2. What Are the Annual State EGU NOXEmissions Budgets? a. For States Affected by the CAIR FIP

   For the proposed Federal CAIR annual NOXcap and trade program, State NOXemissions budgets--for the 23 States and the District of Columbia that are required by CAIR to control annual NOX--are provided in Table V-1, below. These annual NOXbudgets are the same as the budgets shown in Table V-2 of the CAIR NFR preamble (70 FR 25231). Table V-1, below, also includes annual NOXbudgets that EPA proposed for Delaware and New Jersey (these are the same budgets that were included in Table IV-1 in ``Inclusion of Delaware and New Jersey in the Clean Air Interstate Rule: Proposed Rule'' (70 FR 25416)). See section VI in this preamble for EPA's proposed methodology for allocating annual NOX allowances to sources in the Federal CAIR cap and trade programs.

   b. For States Affected by the Section 126 Response

   As explained in section III in this preamble, the EPA is proposing to deny the ozone portion of the section 126 petition. Therefore, the Agency is not proposing ozone season NOXState budgets for purposes of the section 126 remedy. 4. What Are the Amounts of Allowances Available in the State Annual NOXCompliance Supplement Pools?

   The CAIR established State Compliance Supplement Pools (CSP) of annual NOXallowances of vintage 2009. Under CAIR, a State that elects to achieve its CAIR annual NOXreduction requirements by creating an annual NOXcap and trade program can allocate CSP allowances (using mechanisms specified in CAIR) to its sources for use in complying with such an annual NOXprogram (see section VII in the CAIR NFR preamble for discussion, 70 FR 25255- 25273).

   Today's proposed Federal CAIR annual NOXcap and trade program includes the same State CSP amounts as were established in CAIR. See section V in the CAIR NFR preamble (70 FR 25231-25232), as well as the technical support document entitled ``Regional and State SO2and NOXEmissions Budgets,'' March 2005 (in the CAIR docket) for discussion of the Agency's process for determining the annual NOXCSP amounts for each CAIR State. The Agency is not inviting comment on the CSPs established in CAIR.

   For the proposed Federal CAIR annual NOXcap and trade program, the CSP amount for each State is provided in Table V-3, below. These are the same CSP amounts as shown in the CAIR NFR preamble, Table V-3 (70 FR 25232). The CSP amounts for Delaware and New Jersey--if these two States are part of the final CAIR annual NOX requirements as the Agency has proposed--are also shown in Table V-3 below, as well as in Table V-3 in the CAIR NFR preamble (70 FR 25232) and in Table IV-3 in ``Inclusion of Delaware and New Jersey in the Clean Air Interstate Rule: Proposed Rule'' (70 FR 25417). See section VI in this preamble for EPA's proposed methodology for allocating CSP allowances to sources for the Federal CAIR annual NOXcap and trade program.

   VI. Proposed Federal CAIR NOXand SO2Cap and Trade Programs for EGUs

1. Purpose of Federal CAIR NOX and SO2 Cap and Trade Programs and Relationship to the Section 126 Petition and the CAIR

   In today's action, EPA is proposing Federal CAIR NOXand SO2cap and trade programs for EGUs as the control remedy for both the CAIR FIP and the section 126 response, should EPA make any section 126(b) findings (see section VI.C., below, for applicability provisions).

   The Agency is proposing regulatory text for the CAIR FIP rules in today's action. Regulatory text for the section 126 remedy would be largely the same. The proposed new Federal NOXand SO2cap and trade programs will be located in part 97 in title 40 of the CFR.

   The Agency proposes three separate Federal CAIR cap and trade programs: (1) SO2; (2) NOX; and (3) ozone season NOX. Emissions cap and trade programs are a proven method for achieving highly cost-effective emissions reductions while providing regulated sources of emissions with flexibility in adopting compliance strategies.

   Participation in the proposed Federal CAIR NOXand SO2cap and trade programs would be mandatory for all sources covered by the final CAIR FIP or by a final section 126(b) finding in response to the North Carolina petition. Note that, as discussed in section I in today's preamble, EPA is proposing to deny the section 126 petition with respect to the 8-hour ozone NAAQS, therefore the section 126 remedy would not include an ozone season NOXprogram.

   The emission sources that the Agency is proposing to include in the Federal CAIR NOXand SO2cap and trade programs-- EGUs fitting the applicability requirements described in section VI.C, below--are the same types of sources included in the CAIR NOXAnnual Trading Program, CAIR NOXOzone Season Trading Program, and CAIR SO2Trading Program (contained in part 96) that EPA promulgated as model trading rules that States may elect to use in responding to the CAIR. The emission sources identified in today's proposal are the sources for which EPA assumed emission reductions in determining the regionwide emission reduction requirements and calculating the State emission budgets in CAIR. (As discussed in section VII, below, EPA is proposing certain revisions clarifying the EGU definition in CAIR, and the proposed applicability provisions in the Federal CAIR trading programs are consistent with those proposed revisions.)

   The CAIR established State EGU emissions budgets that each State would use to determine its required emissions reductions. The proposed Federal CAIR cap and trade programs set specific rules for EGUs to decrease NOXand SO2emissions sufficiently to achieve emission reductions that are required under CAIR. The proposed section 126 remedy is limited to the set of States that North Carolina named in its petition and for which EPA makes a positive determination (see section III, above). The named States are a geographic subset of the CAIR States. Each of the three actions--the CAIR, the proposed CAIR FIP, and the proposed section 126 remedy--aim to reduce the transport of PM2.5precursors by controlling emissions from sources in a given State that are found to be contributing significantly to nonattainment and maintenance in another State. The CAIR and the proposed CAIR FIP also aim to reduce transport of ozone precursors by controlling emissions from sources in a given State that are found to be contributing significantly to nonattainment and maintenance in another State.

   The EPA intends that if States choose to meet their emission reduction obligations under CAIR by adopting the SIP model cap and trade rules and participating in the EPA administered trading programs, such participation will be fully integrated with Federal CAIR NOXand SO2cap and programs that EPA may promulgate in a final FIP or in a final section 126 response. Integration is possible because, as noted above, the CAIR, a corresponding FIP, and the section 126 remedy all seek to mitigate transport of emissions from upwind sources that significantly contribute to downwind nonattainment of the PM2.5NAAQS, and the CAIR and a corresponding FIP both seek to mitigate such transport with regard to the 8-hour ozone NAAQS. Further, the sources covered in the CAIR SIP model cap and trade programs are the same types of sources named in the section 126 petition (except that the petition names a subset of the States affected by CAIR), and are the same as the sources that EPA proposes to regulate in the proposed FIP and section 126 remedy.

   In order to be eligible to participate in an emissions cap and trade program, the Agency believes that there are two principal criteria that sources must meet, as stated in the supplemental proposal for the NOXSIP Call (62 FR 25923). The first criterion requires that sources be able to account accurately and consistently for all of their emissions to ensure the trading program goal of maintaining emissions within a cap. Emissions monitoring must be accurate and consistent among all sources so that each allowance represents the same amount of emissions. The second criterion for participation in a trading program is the ability to identify a responsible party for each regulated source who would be accountable for demonstrating and ensuring compliance with the program's provisions. The EPA believes that today's proposed rule meets those criteria. The Agency also believes that, because today's proposal contains the same mandatory program elements as are in the part 96 CAIR SIP model trading programs, and is designed to meet the same environmental goals and caps sources at the same levels as those model trading programs, it is appropriate to design CAIR FIP and section 126 trading programs that are integrated with the CAIR SIP trading programs.

   Under this scenario of common trading programs (i.e., integrated FIP-section 126-SIP for NOXannual, NOXozone season, and SO2trading programs), sources subject to Federal CAIR trading programs under the FIP or the section 126 remedy, and sources in States choosing to participate in the EPA-administered CAIR SIP trading programs could trade allowances with one another under common emissions caps across participating States. Integration of the trading programs reduces the possibility of inconsistent or conflicting deadlines or requirements, increases the potential cost savings for sources, and streamlines program administration. Unnecessary inconsistency in trading programs could hamper sources' ability to plan and achieve the needed reductions as cost effectively as possible. In addition, if a State submitted a SIP including CAIR EPA-administered emissions trading programs after EPA had established Federal programs under a FIP or section 126 response, disruptions to sources that would shift from regulation under a FIP or section 126 remedy to regulation under a SIP would be minimized.

   [[Page 49727]]

   The EPA proposes, in part 97, to establish the geographic boundaries of the common trading programs as those States submitting SIPs in response to the CAIR, or subject to FIPs, and/or the sources in States for which EPA makes a positive finding for the section 126 petition. The EPA would administer these common trading programs in collaboration with affected States.

   Today, the Agency proposes Federal CAIR NOXand SO2cap and trade programs for the FIP or section 126 remedy that are virtually the same as the CAIR SIP model trading programs (which are the model trading programs that States may choose to adopt in response to CAIR). Although EPA intends the proposed Federal CAIR cap and trade programs to be as similar as possible to the CAIR SIP model trading rules, the Agency is proposing certain differences as described below. The differences arise primarily from the need for Federal implementation of the programs rather than State implementation and to facilitate transfer from Federal to State-implemented programs. For example, under today's proposal, the Agency determines NOXallowance allocations for each unit in the Federal CAIR annual and ozone season NOXcap and trade programs, rather than EPA simply providing a recommended methodology for States to use to determine allocations in CAIR SIP NOXtrading programs. Note that today's proposed Federal CAIR cap and trade programs include all of the mandatory elements that States are required to include in their SIPs in order to participate in the EPA-administered cap and trade programs for CAIR.

   As noted in section IV in this preamble, the Agency proposes to provide States that are subject to today's proposed Federal requirements with the option to submit abbreviated SIP revisions covering specific elements of the Federal trading programs without submitting full SIP revisions to meet the requirements of CAIR. The Agency would accept abbreviated SIP revisions for the following 4 specific elements of the Federal trading programs: (1) Provisions for non-EGUs to opt-in to the Federal trading programs, (2) allocating annual and/or ozone season NOXallowances to individual sources in the State, (3) allocating allowances from the annual NOXCompliance Supplement Pool (CSP) to individual sources in the State, and (4) including NOXSIP Call trading sources that are not EGUs under CAIR in the Federal CAIR ozone season NOXcap and trade program. The Agency discusses each of these elements further below.

   By proposing to accept such abbreviated SIP revisions, the Agency intends to increase the options available for States to comply with CAIR. A State could choose to retain control of these specific elements of the trading programs, without submitting a full SIP revision to meet the requirements of CAIR.

   As explained in the CAIR NFR, States have until September 11, 2006 to submit to the Agency revisions to their SIPs that meet the requirements of CAIR. The Agency proposes that, for abbreviated SIP revisions addressing the specific elements identified in today's proposal, States have until March 31, 2007 to make their submissions. The EPA proposes to allow States to submit abbreviated SIP revisions later than full revisions because the Agency anticipates that we will be able to complete the approval process more quickly for abbreviated SIP revisions due to their narrower scope. If States submit approvable full or abbreviated SIP revisions by these dates, the Agency believes it will be able to approve the revisions in time to record State NOXallocations in source accounts by December 2007 for the first NOXcontrol period for any State submitting revisions that include NOXallocations. See section VI.D. in this preamble for a detailed discussion of timing considerations with respect to NOXallocations.

   The Agency proposes to include appendices in part 97 that will list any States with approved abbreviated SIP revisions covering non-EGUs opt-ins, allocating NOXallowances, distributing CSP allowances, or including non-CAIR NOXSIP Call trading sources in the Federal CAIR ozone season NOXtrading program.

   The EPA requests comment on the proposed option for States to submit abbreviated SIPs covering specific elements of the Federal trading programs.

2. Overall Structure of the Proposed Federal CAIR Cap and Trade Programs

   In the CAIR NFR, the Agency provided model rules for the CAIR NOX, CAIR ozone season NOX, and CAIR SO2trading programs that States can use to meet the emission reduction requirements in the CAIR (in part 96). The proposed Federal CAIR cap and trade programs are based on these model rules. The EPA designed these rules to be similar to the NOXSIP Call model trading rules (also in part 96) and to coordinate with the Acid Rain Program.

   The Agency proposes in today's action that the mandated emission reductions will be achieved from EGUs (see section VI.C, below, for discussion of proposed applicability provisions). Descriptions of each of the proposed Federal CAIR cap and trade programs (i.e., the SO2program, NOXannual program, and NOXozone season program) are presented below.

   The proposed Federal CAIR cap and trade programs rely on the detailed unit-level emissions monitoring and reporting procedures of part 75 and consistent allowance management practices. All affected sources would be required to monitor and report their emissions using part 75. Source information management, emissions data reporting, and allowance trading would be accomplished using on-line systems similar to those currently used for the Acid Rain SO2and NOXSIP Call Programs.

   Penalty provisions for excess emissions under the CAIR SIP model trading programs are described in the CAIR NFR preamble (70 FR 25274). The Agency intends the penalty provisions for excess emissions in today's proposal to be identical to the provisions in the CAIR. As discussed in section VII in today's preamble, the Agency is proposing revisions to the excess emission penalties in the CAIR SO2 trading program to clarify the penalties for units that have excess emissions under both the Acid Rain Program and the CAIR SO2 trading program. The excess emissions penalty provisions in today's proposed Federal NOXand SO2cap and trade programs would be identical to the penalty provisions in the CAIR if the proposed revisions to the CAIR SO2trading program penalties are finalized. 1. SO2Program

   The proposed Federal CAIR SO2cap and trade program would require affected sources to hold SO2allowances sufficient to cover their emissions for each control period. This proposed program is based on the existing Acid Rain Program and would rely on title IV SO2allowances, in the same way that the CAIR SO2model trading rule relies on title IV allowances.

   As in the CAIR SIP SO2model trading program, SO2reductions for the Federal CAIR SO2cap and trade program would be achieved by requiring sources to retire, in most cases, more than one title IV allowance for each ton of SO2 emissions. Sources could use pre-2010 title IV SO2 allowances for compliance with the Federal CAIR SO2cap and trade program at a 1-to-1 ratio (i.e., SO2allowances of vintage 2009 and earlier would offset one ton of SO2 emissions). Allowances of vintages 2010 through

   [[Page 49728]]

   2014 would offset 0.5 tons of emissions (i.e., such allowances would need to be retired at a ratio of 2-to-1 for CAIR compliance, in other words 2 allowances for every ton of emissions). Allowances of vintages 2015 and beyond would offset 0.35 tons of emissions (i.e., such allowances would need to be retired at a ratio of 2.86-to-1, in other words 2.86 allowances for every ton of emissions). Thus, the emission value of an SO2allowance would be independent of the year in which it is used, but rather would be based on its vintage (i.e., the year in which the allowance is issued). These SO2 allowance retirement ratios are identical to the retirement ratios in the CAIR NFR (see discussion in section VII in the CAIR NFR preamble at 70 FR 25255-25273, as well as in section IX at 70 FR 25290-25291).

   The Agency proposes to use the single term, ``CAIR SO2 allowance'' to refer to an SO2allowance under a CAIR SIP, CAIR FIP, or section 126 response.\11\ A CAIR SO2allowance could be used for compliance with the SO2allowance-holding requirement in a CAIR SIP, CAIR FIP, or section 126 SO2 trading program. Sources in States governed by any of these three SO2trading programs could trade CAIR SO2 allowances with each other.The CAIR SIP SO2model trading rule (upon which the proposed Federal CAIR SO2program is based) is included in subparts AAA through III of part 96 (70 FR 25362- 25382). Section VIII in the CAIR NFR preamble describes the CAIR model cap and trade programs (70 FR 25273-25289).

   \11\ A CAIR SO2allowance is a title IV SO2allowance. For purposes of compliance with the EPA- administered SIP SO2trading program or with the Federal SO2trading program in today's proposal, the value of such SO2allowances are discounted based on the allowance vintage year, as explained above.

   2. NOXProgram

   The proposed Federal CAIR annual NOXcap and trade program would require affected sources to hold annual NOX allowances sufficient to cover their emissions for each control period. The proposed program would rely on CAIR annual NOX allowances that would be allocated to affected sources by the EPA (see section VI.D. for the Agency's proposed NOXallocation methodology). As in CAIR, an annual NOXallowance would authorize the emission of one ton of NOX(see the proposed regulatory text for definitions).

   As in the CAIR annual NOXprogram, the Agency is proposing a Compliance Supplement Pool (CSP) of allowances that would be allocated to sources and could then be used for compliance with the Federal CAIR annual NOXcap and trade program. As explained in the CAIR NFR, the Agency apportioned a regionwide pool of about 200,000 CSP allowances to the CAIR States (see 70 FR 25231-25232). Those State CSP amounts are provided in Table V-3 in this preamble. The Agency is not inviting comment on the apportionment of CSP allowances as determined in CAIR.

   For the Federal annual NOXcap and trade program in today's action, the Agency proposes that, for each affected State, we would allocate to sources in that State an amount of CSP allowances up to the amount that was apportioned to the State in CAIR. The Agency's proposed methodology to allocate CSP allowances to sources is described below, in section VI.D.

   The Agency proposes that ozone season NOXallowances issued under the NOXSIP Call or under the Federal CAIR ozone season cap and trade program could not be used for compliance with the Federal CAIR annual NOXreduction requirement (which is the same restriction as in the CAIR SIP model trading rules).

   The Agency proposes to use the single term, ``CAIR NOX allowance'' to refer to a NOXallowance issued under a CAIR SIP, CAIR FIP, or section 126 response. A CAIR NOXallowance could be used for compliance in a CAIR SIP, CAIR FIP, or section 126 NOXtrading program. Sources in States governed by any of these three annual NOXtrading programs could trade CAIR NOXallowances with each other.

   The CAIR SIP NOXannual model trading rule (upon which the proposed Federal CAIR NOXannual program is based) is included in subparts AA through II of part 96 (70 FR 25339-25362). Section VIII in the CAIR NFR preamble describes the CAIR model cap and trade programs (70 FR 25273-25289). 3. Ozone Season NOXProgram

   The proposed Federal CAIR ozone season NOXcap and trade program would require affected sources to hold CAIR ozone season NOXallowances sufficient to cover their emissions for each control period. For the proposed ozone season program, the control period would extend from May 1 through September 30 for each year of the program. As in CAIR, a NOXozone season allowance would authorize the emission of one ton of NOXduring the ozone season (see the proposed regulatory text for definitions).

   The proposed program would rely on CAIR ozone season NOX allowances that would be allocated to affected sources by the EPA (see section VI.D. for the Agency's proposed NOXallocation methodology). In addition, pre-2009 NOXSIP Call allowances could be banked into the proposed Federal CAIR ozone season NOXprogram and used by affected sources for compliance with that program. The Agency proposes that NOXallowances issued under the Federal CAIR annual NOXprogram could not be used for compliance with the Federal CAIR ozone season NOX reduction requirement (which is the same restriction as in the CAIR SIP model trading rules).

   As discussed in the CAIR NFR, certain emissions sources that do not fit the applicability requirements of CAIR are included in the existing EPA-administered NOXBudget Trading Program under the NOXSIP Call. (The types of NOXBudget Trading Program units that are not EGUs under CAIR include industrial boilers and turbines, cement kilns, and small EGUs.) As explained in the CAIR NFR, EPA will no longer administer the NOXSIP Call ozone season cap and trade program after the 2008 ozone season (see 70 FR 25290). The CAIR NFR provides that States that choose to participate in the CAIR EPA-administered ozone season NOXcap and trade program may choose whether or not to bring their non-CAIR NOXSIP Call trading sources into the CAIR ozone season trading program, through their SIP revision. See section VII in the CAIR NFR (70 FR 25255-25273) and section IX.A. (70 FR 25289-25290).

   As discussed above, the Agency is proposing that States may choose to submit an abbreviated SIP revision to bring their non-CAIR NOXSIP Call trading sources into the proposed Federal CAIR ozone season NOXcap and trade program. The abbreviated SIP revision would increase a State's ozone season NOXtrading budget under the proposed Federal CAIR ozone season NOXcap and trade program by an amount equal to the portion of the State's NOXSIP Call State trading budget that is attributed to such units.

   The Agency proposes to use the single term, ``CAIR Ozone Season NOXallowance'' to refer to an ozone season NOX allowance issued under a CAIR SIP or CAIR FIP. A CAIR ozone season NOXallowance could be used for compliance in a CAIR SIP or CAIR FIP ozone season NOXtrading program. Sources in States governed by either of these ozone season NOXtrading programs could trade CAIR Ozone Season NOXallowances with each other.

   The CAIR SIP NOXozone season model trading rule, upon which the proposed Federal CAIR NOXozone

   [[Page 49729]]

   season program is based, is included in subparts AAAA through IIII of part 96 (70 FR 25382-25405). Section VIII in the CAIR NFR preamble describes the CAIR model cap and trade programs (70 FR 25273-25289).

3. Sources Affected Under the Proposed Federal CAIR Cap and Trade Programs

   Under the proposed Federal CAIR cap and trade programs, only EGUs are subject to the proposed rules. The Agency intends the applicability provisions for the proposed Federal CAIR trading programs to be identical to the applicability provisions for the CAIR SIP model trading programs.

   In today's action, the Agency is proposing two revisions to the applicability provisions that were finalized in the CAIR SIP model trading rules (see section VIII.C. in the CAIR NFR preamble for applicability discussion at 70 FR 25276-25278 and see section VII in today's preamble for proposed changes to the CAIR EGU definition). The applicability provisions in today's proposed Federal CAIR trading programs are identical to the applicability provisions that would apply for CAIR if the Agency finalizes its proposed revisions to the CAIR model trading rules.

   The proposed revisions to the applicability provisions in CAIR are intended to provide clarity and also to align the provisions more closely with the provisions in the title IV Acid Rain Program. The proposed revisions include adding an exemption for certain solid waste incinerators and exempting existing units that have not served a generator since before November 15, 1990. Each of these revisions is discussed below.

   The status of solid waste incinerators under the CAIR as finalized is unclear. The Agency proposes a revision to the applicability provisions that would establish a specific exemption for certain solid waste incinerators. In the CAIR NFR, the Agency applied the CAIR model trading programs to any stationary, fossil-fuel-fired boiler or stationary, fossil-fuel-fired combustion turbine serving at any time, since the start-up of the unit's combustion chamber, a generator with nameplate capacity of more than 25 MWe producing electricity for sale (with exclusions for certain cogeneration units). Under the current definition, units would be considered fossil-fuel-fired if they burned any fossil fuel. Because solid waste incinerators usually use fossil fuel, at least to start up, and because they may burn fossil-fuel derived products (such as tires), they are often considered fossil- fuel-fired. Therefore, to the extent that such incinerators are connected to a generator of capacity greater than 25 MWe that generated electricity for sale, they would be considered affected units under CAIR. However, in the record for the CAIR, EPA stated that the CAIR requirements do not reflect any emission reductions from solid waste incinerators \12\. Therefore, the EPA is proposing an exemption for certain solid waste incinerators. The proposed exemption is analogous to an exemption for such units under the Acid Rain Program. The Agency proposes this exemption as a revision to the applicability provisions in the CAIR and proposes the identical exemption for the Federal CAIR trading programs.

   \12\ ``Corrected Response to Significant Public Comments on the Proposed Clean Air Interstate Rule,'' April 2005, Docket OAR-2003-0053-2172.

   In addition, the status, under CAIR, of units that formerly generated electricity for sale but stopped doing so many years ago warrants further clarification. As finalized in CAIR, the applicability provisions include units serving ``* * * at any time, since the start- up of the unit's combustion chamber, a generator * * *'' The Agency is proposing to revise the applicability provisions to exempt existing units that have not served a generator since before November 15, 1990. This proposed exemption is analogous to the approach under the Acid Rain Program. The Agency proposes this exemption as a revision to the applicability provisions in the CAIR and proposes the identical exemption for the Federal CAIR trading programs.

   The Agency proposes that, in any jurisdiction for which a final CAIR FIP or section 126 response is promulgated, the following units will be subject to the Federal CAIR trading programs (i.e., to the Federal CAIR SO2, NOXannual, or NOX ozone season programs, as appropriate).

   Except for a unit that qualifies as a cogeneration unit or a solid waste incinerator (see below), an affected unit is any stationary, fossil-fuel-fired boiler or stationary, fossil-fuel-fired combustion turbine serving at any time, since the later of November 15, 1990 or the start-up of the unit's combustion chamber, a generator with nameplate capacity of more than 25 MWe producing electricity for sale.

   Cogeneration Unit Exemption

   As in the CAIR NFR, certain cogeneration units would be exempt from the proposed Federal CAIR cap and trade programs. Cogeneration units include units having equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through sequential use of energy and meeting certain operating and efficiency standards. The program has different applicability provisions for non-cogeneration units and cogeneration units. Any cogeneration unit, serving (since the later of November 15, 1990 or the start-up of the unit), a generator with a nameplate capacity of greater than 25 MW and supplying more than \1/3\ potential electric output capacity and more than 219,000 MW-hrs annually to any utility power distribution system for sale, would be subject to the requirements of the proposed Federal CAIR trading rules. Otherwise, the unit would qualify for an exemption under the Federal rules. This cogeneration unit exemption is identical to the exemption in the CAIR NFR. (Note that some language to clarify application of the exemption is proposed for the CAIR SIP trading programs and the same language is also included in the proposed Federal trading programs.) Section VIII.C.3. of the CAIR NFR preamble describes the cogeneration unit exemption and discusses the specific elements of how units would qualify and remain qualified for the exemption (70 FR 25276-25278).

   Solid Waste Incinerator Exemption

   As explained above, the Agency is proposing today to provide an exemption for certain solid waste incinerators in the Federal CAIR cap and trade programs and to revise the provisions in the CAIR to exempt certain solid waste incinerators.

   Specifically, the Agency proposes that, for a solid waste incineration unit commencing operation before January 1, 1985, for which the average annual fuel consumption of non-fossil fuels during 1985-1987 exceeded 80 percent and during any 3 consecutive calendar years after 1990 the average annual fuel consumption of non-fossil fuels exceeds 80 percent, the unit is not subject to the Federal CAIR cap and trade programs.

   The Agency also proposes that, for a solid waste incineration unit commencing operation on or after January 1, 1985, for which the average annual fuel consumption of non-fossil fuels for the first 3 calendar years of operation exceeds 80 percent and during any 3 consecutive calendar years after 1990 the average annual fuel consumption of non- fossil fuels exceeds 80 percent, the unit is not subject to the Federal CAIR cap and trade programs.

   [[Page 49730]]

   Individual Unit Opt-Ins

   Today's proposal includes provisions for individual units to opt-in to the Federal CAIR trading programs. However, EPA proposes that those provisions would become applicable to sources in a given State only if the State chooses to submit an abbreviated SIP revision that would provide for the inclusion of non-EGU opt-ins in the Federal CAIR trading programs.

   The CAIR final rule includes provisions for individual unit opt-ins in the CAIR SIP model trading programs. As discussed in CAIR, States choosing to participate in the EPA-administered CAIR trading programs can choose whether or not to include opt-in provisions in their CAIR SIP revisions. If States choose to include opt-in provisions, they must include the provisions provided in the CAIR SIP model trading rules.

   The Agency generally believes that States should have the option of including provisions for individual unit opt-ins in the CAIR SIP trading programs. The EPA considered requiring all States to have opt- in provision in the proposed Federal CAIR trading programs. By not requiring opt-in provisions in all States covered by the proposed Federal trading programs, the Agency seeks to preserve the States' flexibility to decide whether to allow opt-in units.

   If EPA were to implement Federal CAIR trading programs with required provisions allowing individual units to opt-in, then some units may opt-in to the Federal programs. If the Agency subsequently approved a CAIR SIP revision that did not include opt-in provisions, then any units in the affected State that had opted-in under the Federal programs would be stranded. Such units would likely have made decisions--such as to install emission control equipment--based on participation in a trading program in which they would no longer be able to participate. The alternative to stranding such units would be for a State that would not otherwise choose to implement the opt-in provisions to implement such provisions at least for the past opt-in units. Thus, in order to preserve States' flexibility with regard to opt-ins the Agency does not propose to require the opt-in provisions to apply in all States under the Federal CAIR trading programs, but proposes that each State have the option of activating the opt-in provisions in the Federal CAIR programs through an abbreviated SIP revision.

   The Agency proposes that if States choose to submit abbreviated SIP revisions to provide for the inclusion of non-EGU opt-ins in the Federal CAIR trading programs, the SIP revisions must include the opt- in provisions that are provided in the CAIR final rule. See section VIII.G. in the CAIR NFR preamble for discussion of opt-in provisions (70 FR 25286-25288).

4. Allocation of NOXEmission Allowances to Sources

   For States that choose under CAIR to participate in the EPA- administered annual and/or ozone season NOXcap and trade programs (adopting the CAIR SIP model trading rules), the EPA provided in the CAIR NFR an example methodology for allocating NOX allowances to individual sources. See section VIII.D. of the CAIR NFR preamble (70 FR 25278-25282).

   For the Federal CAIR NOXcap and trade programs, the Agency is proposing to use a NOXallocation methodology that is consistent with the CAIR SIP model trading rules. Within each affected State, the Agency would allocate (i.e., distribute) to sources a total amount of allowances authorizing an emissions tonnage that equals the State's NOXbudget. The Agency's proposed NOXallocation methodology is described below.

   Timing of NOX Allocations

   For the reasons discussed in section IV in today's preamble, the EPA intends to finalize a CAIR FIP in March 2006. By finalizing a FIP, the EPA would in no way preclude a State from developing its own SIP either to adopt the CAIR model trading rules (with any discretionary elements allowed by the CAIR rule, including allocation of unit-by-unit NOXallowances) or to meet the CAIR emission reduction requirements through different measures of the State's choosing.

   The Agency's preference is for States to make decisions about NOXallocations for their sources. The EPA intends to determine Federal unit-by-unit NOXallocations (with opportunity for public comment). However, we intend to only record those Federal allocations in allowance accounts for sources located in a State without a timely, approved CAIR SIP (or timely, approved abbreviated CAIR SIP revision providing for State allocations).

   In considering when to record Federal NOXallocations in source accounts, the Agency seeks to balance the following two goals: (1) To provide certainty to sources regarding their CAIR NOX allocations and time for sources to make compliance decisions, and (2) to provide States choosing to allocate CAIR NOXallowances with time to do so and EPA with time to approve SIP revisions that include State allocations. Taking into consideration the CAIR SIP submittal dates (for full or abbreviated revisions), the amount of time needed by the Agency to approve SIP revisions, and the amount of time remaining before the initial CAIR control period, the EPA developed a proposed schedule for recording NOXallocations in source accounts. The Agency's proposed NOXallocation schedule is presented below. The EPA seeks comment on this proposed schedule.

   The Agency will endeavor to work with States to ensure that we can approve SIP revisions and record State NOXallocations in source accounts. The EPA intends to act in such a way that, once Federal NOXallocations are recorded for a particular control period (which would only occur in the absence of a timely, approved full CAIR SIP revision, or timely, approved abbreviated CAIR SIP revision containing allocations), we would not approve overlapping State allocations for that same control period.\13\ Rather, EPA will work with the States to approve SIP revisions with State allocations for control periods that begin upon the expiration of a control period for which Federal allocations have been recorded in source accounts. It would be highly disruptive to the allowance market if Federal allocations that had been recorded and traded on the market could subsequently be rendered invalid due to approval of overlapping State allocations for the same control period.

   \13\ As discussed in the CAIR NFR preamble (70 FR 25278), each State has the flexibility to allocate its allowances however they choose (within their State budgets) so long as certain timing requirements are met. Today's preamble discusses the approval of State allocations within the context of coordinating timing for recording Federal allocations--note that this discussion is not intended to imply any less flexibility for States in their choice of allocation methodology than the flexibility provided in CAIR.

   The discussion in this section is focused on the timing for recordation of Federal allocations in coordination with approval of SIP revisions and recordation of State allocations--assuming States choose to participate in the EPA-administered CAIR NOXtrading programs. The Agency would also carefully consider the timing of a transition from Federal to State-implemented programs for any State choosing to use a method other than the EPA-administered State CAIR trading programs to meet their CAIR obligations.

   As discussed further below, the EPA intends to record Federal allocations 1 year at a time for the initial control periods. In this manner, even if a State does not have an approved CAIR SIP

   revision in time for the Agency to record State allocations for the first control period, it would be possible to record State allocations for future control periods. The Agency strongly urges States to submit CAIR SIP revisions (full or abbreviated revisions) to the Agency in a timely manner, and we intend to work with States and ensure that we would not have overlapping allocations for any control period.

   As explained in the CAIR NFR, the States have until September 11, 2006 to submit full CAIR SIP revisions to the Agency. For a State that chooses to participate in the EPA-administered CAIR SIP NOX trading programs this SIP revision would be required to include the State's NOXallocation methodology. The EPA anticipates that it may require about a year to approve a full SIP submission. The CAIR SIP rules require States to submit their first set of CAIR NOXallocations to EPA by October 31, 2006.

   As discussed above, the Agency is proposing that States may choose to submit an abbreviated SIP revision to allocate NOX allowances to individual sources in their State (for the annual and/or ozone season Federal CAIR NOXtrading programs). In this way, a State could choose to allocate NOXallowances to its sources while letting the FIP (or section 126 remedy) control all other aspects of the trading programs. Through an abbreviated SIP revision, a State can also ensure that its allocations will apply even though its full SIP revision is still undergoing EPA review. Note that States could also choose to address non-EGU opt-ins, allocation of CSP allowances, and/or inclusion of non-CAIR NOXSIP Call trading sources in an abbreviated SIP revision. The Agency proposes that States would have until March 31, 2007 to submit their allocation methodology in an abbreviated SIP revision. The EPA proposes to allow States to submit abbreviated SIP revisions later than full revisions because we anticipate that we will be able to complete the approval process more quickly for abbreviated SIP revisions due to their narrower scope. The Agency proposes that the State would have until October 31, 2007 to submit their first set of CAIR NOX allocations pursuant to an abbreviated SIP revision. The proposed dates for recording NOXallocations, discussed below, would be the same whether the allocations are approved in a full SIP revision or in an abbreviated revision.

   Assuming that States submit full CAIR SIP revisions by the September 2006 deadline and that EPA can approve the revisions in about a year, and assuming some additional time may be required for coordination between States and EPA before State allocations can be recorded in source accounts, it is reasonable to assume that EPA could record such State allocations by December 1, 2007. Likewise, assuming that States submit abbreviated SIP revisions that address allocations by the March 2007 deadline and that EPA can approve the abbreviated revisions in about 6 months, it is reasonable to assume that EPA could record such allocations by December 1, 2007.

   Therefore, the EPA proposes to record NOXallocations in source accounts for the 2009 control period by December 1, 2007. If a State's timely NOXallocations are approved then the Agency would record State allocations for the 2009 control period. However, for any CAIR State for which a SIP is not approved by December 1, 2007, the EPA would record Federal NOXallocations for 2009. Recording NOXallocations by December 2007 for the 2009 control period provides affected sources with certainty of their allocations 1 year in advance of the beginning of the control period.

   The Agency proposes to record Federal NOXallocations in source accounts 1 year at a time for the 2009 and 2010 control periods in order to provide flexibility to States. If EPA records Federal allocations for the 2009 control period and subsequently approves a State's timely SIP revision including NOXallocations (a full or abbreviated revision), the Agency would record the State's allocations for future years. The Agency does not intend to approve State NOXallocations for a particular control period that would overlap with Federal allocations already recorded in source accounts. Provisions for withdrawal of CAIR FIPs and section 126 remedies are discussed elsewhere in this preamble.

   The EPA proposes to record NOXallocations in source accounts by December 1, 2008 for the 2010 control period. If a State's NOXallocations are approved by then, the Agency may record State allocations for the 2010 control period. However, for any CAIR State for which a SIP is not approved by December 1, 2008, the EPA would record Federal NOXallocations for 2010. Therefore, if a State obtained SIP approval after December 1, 2007 but before December 1, 2008, the State's NOXallocations may be recorded in source accounts for the 2010 control period.

   The Agency proposes to record NOXallocations in source accounts by December 1, 2009 for the 2011-2013 control periods. Therefore, if a State obtained SIP approval after December 1, 2008 but before December 1, 2009, the State's NOXallocations may be recorded in source accounts for the 2011-2013 control periods. However, for any CAIR State for which a SIP is not approved by December 1, 2009, the EPA would record Federal NOXallocations for 2011-2013.

   Beginning with the 2014 control period and for each control period thereafter, EPA proposes to record Federal NOXallocations in source accounts by December 1 of each year for the control period in the fourth year after the recordation year, thereby providing allowances about 3 years in advance for sources to plan their compliance strategies. For example, EPA would record allocations for the 2014 control period by December 1, 2010.

   The CAIR requires States to submit to the Agency their unit-by-unit NOXallocations for a given year no less than 3 years prior to the applicable control year to ensure sources have time to plan for compliance (see CAIR NFR preamble at 70 FR 25278-25279)\14\. In today's proposal, EPA would record Federal NOXallocations in source accounts (in absence of approved timely SIP revisions) with less than 3 years lead time for the first 4 control periods, i.e., for 2009 through 2012. Beginning with the 2013 control period, however, we propose to record Federal allocations with about 3 years' lead time. This proposed schedule is intended to balance the need to provide sources their allocations in advance to facilitate planning for compliance, with the need to preserve opportunities for States to allocate allowances to sources if they choose. The EPA acknowledges that it is preferable for sources to have at least 3 years lead time to the extent feasible. We strongly urge States to submit timely CAIR SIP revisions so that we can approve revisions and record State allocations in source accounts according to the schedule in CAIR, which would provide at least 3 years notice for all but the first control period.

   \14\ As discussed in the CAIR NFR (70 FR 25278), based on a SIP submission deadline in September 2006 there would be less than 3 years notice of allocations for the first control period.

   Table VI-1, below, summarizes the Agency's proposed timing for recording Federal NOXallocations in source accounts. The table shows the timing scheme through the 2016 control period. Timing for subsequent control periods would follow the same pattern as is shown for 2014-2016, i.e., allocations would by recorded by 3 years in advance of the control period.

December 1, 2011....... 3 years. 2016.................. December 1, 2012....... 3 years.

   The Agency intends to publish its determination of Federal NOXallocations for 2009-2014 in a single notice (with opportunity for comment) prior to December 1, 2007. The Agency would publish its determination of Federal NOXallocations (with opportunity for comment) prior to December 1 of each year for future years. For example, we would publish Federal NOXallocations for the 2015 control period during 2011.

   \15\ The Agency does not intend to wait until December 1, 2007 to record State NOXallocations for the 2009 control period but rather would record approved allocations as soon as feasible and according to the schedule in the CAIR SIP rules. The EPA proposes that we would not record Federal NOX allocations for any State until December 1, 2007 for the 2009 control period in order to provide the opportunity for State allocations to be submitted and approved. The Agency proposes the same process for future years as well (i.e., we would record State allocations for the 2010 control period as soon as is feasible and according to the schedule in the CAIR SIP rules, but would wait until December 1, 2008 to record Federal allocations for 2010 in order to provide opportunity for States to allocate).

   The Agency intends to work with the States to ensure that for any State that chooses to allocate NOXallocations--either through a full SIP revision or an abbreviated revision--the Agency will record the State's allocations (contained in an approved SIP revision) in source accounts rather than record Federal allocations, as soon as it is feasible. The proposed timing scheme for recording Federal NOXallocations is intended to provide States with as much flexibility as is feasible given the available time, while also providing sources time to plan compliance strategies.

   For States choosing to submit full SIP revisions for CAIR, the Agency suggests they could consider designating any of the four specific elements that we propose to accept in abbreviated SIP revisions (e.g., NOXallocations) as being submitted for purposes of both a full SIP revision and an abbreviated revision. Because the Agency anticipates that we would be able to approve abbreviated SIP revisions more quickly than full revisions, a State could, by designating its NOXallocations as an abbreviated SIP revision (as well as being part of a full SIP revision), potentially allow for the allocations portion to be approved more quickly. This might have benefit, for example, in a situation in which it was not feasible to approve a State's full SIP revision before December 1, 2007. If the NOXallocations portion of the revision could be approved by December 1, 2007, then the State's allocations may be recorded in source accounts. Until the full SIP were subsequently approved, the other elements of the trading programs would be controlled by the Federal CAIR programs. Provisions for withdrawal of CAIR FIPs and section 126 responses are discussed elsewhere in this preamble.

   Today the Agency is proposing its NOXallocation methodology for the Federal CAIR NOXcap and trade programs. The EPA intends to publish its initial determination of unit-by-unit Federal CAIR NOXallocations in a subsequent notice of data availability (NODA).\16\ The public will have opportunity to comment on those initial allocations.

   \16\ The Agency will determine Federal NOX allocations based on the best available data. When EPA publishes its NOXallocations, the unit-by-unit list of allocations would not constitute a list of affected sources and should not be interpreted as such.

   In the NODA, the Agency intends to publish its initial NOXallocation determinations for the control periods 2009 through 2014. After public comment, the EPA would publish its final determinations of allocations for 2009 through 2014. Although EPA intends to publish its allocations for 2009 through 2014 in a single notice, the Agency intends to record allocations in source accounts one year at a time for 2009 and 2010 in order to provide flexibility to States.

   Proposed NOX Allocation Methodology

   Today's proposed NOXallocation approach for both annual and ozone season allowances is consistent with the example methodology presented in the CAIR SIP model trading rules. The proposed methodology is the same for annual NOXallowances and for ozone season NOXallowances, except that the ozone season method uses ozone season heat input not annual heat input.

   For existing units, the proposed NOXallocation methodology uses input-based allocations, adjusting the heat input by factors based on fuel type, as described below. As in the example allocation methodology in the CAIR model rules, for existing units the Agency proposes to use heat input based on the average of the 3 highest amounts of a unit's adjusted heat input for 5 years (2000 through 2004). The EPA also asks for comment on using heat input based on 3 or 4 years of data rather than 5 years.

   For new units that have established baselines, allocations would be based on generation using a modified output approach to convert output to heat input (described below), and allocations to existing units would be updated to take into account new generation as new units would be allocated from the pool of allowances shared with existing sources. New units that have not yet established baseline data would be allocated from a new unit set-aside.

   The Agency would allocate from the State's EGU NOX budget for the first 6 control periods (2009 through 2014) for existing sources on the basis of historic baseline heat input. Consistent with CAIR, January 1, 2001 is the proposed cut-off on-line date for considering units as existing units. Allowances for 2015 and later would be allocated from the State's EGU NOXbudget annually, 3 years in advance. These allocations would take into account output data from new units with established baselines (modified by heat input conversion factors to yield heat input numbers, as described below). As new units enter into service and establish a baseline, they would be allocated allowances in proportion to their share of the total calculated heat input. Allowances allocated to existing units would slowly decline as their share of total calculated heat input decreases with the entry of new units (note that once a baseline heat input is established for existing units, this baseline heat input would not change).

   New units that have entered service but have not yet started receiving allowances through the updating of allocations would receive allowances each year from a new unit set-aside. The allowances from the set-aside would be distributed based on a unit's actual emissions from the previous year, which would provide allowances for use in meeting the allowance-holding requirement during the interim period before the unit is allocated allowances on the same basis as existing units. Consistent with the CAIR SIP example allocation methodology, the new unit set-aside would be equal to 5 percent of a State's emission budget for the years 2009-2013 and 3 percent of a State's

   [[Page 49733]]

   emission budget for subsequent years. New units would begin receiving allowances from the set-aside for the control period immediately following the control period in which the new unit commences commercial operation, based on the unit's emissions from the preceding control period. Under the proposed CAIR Federal cap and trade programs, EPA would allocate allowances from the set-aside to all new units in any given year as a group. If there are more allowances requested than in the set-aside, allowances would be distributed on a pro-rata basis.

   As in the CAIR SIP example methodology, after 5 years of operation, a new unit would have an adequate operating baseline of output data to be incorporated into the calculations for NOXallocations to all affected units. The average of the highest 3 years from these 5 years would be multiplied by the applicable heat-input conversion factors to calculate the heat input value used to determine the new unit's allocation from the pool of allowances for all sources. New units would update the heat input numbers only once--for the initial 5 year baseline period after they start operating. As in the CAIR SIP example methodology, existing units as a group would not update their heat input, which would eliminate the potential for a generation subsidy. Retired units would continue to receive allowances indefinitely, thereby creating an incentive to retire less efficient units.

   The Agency seeks comment on its proposed NOXallocation methodology.

   Sources of Data for NOX Allocations

   To determine NOXallocations for purposes of the Federal CAIR cap and trade programs, the Agency proposes to use heat input and fuel type data reported to EPA's Electronic Data Reporting (EDR) system, where available, and to use best available heat input and fuel type data (e.g., data from the Energy Information Administration (EIA)) where EDR data is not available. The Agency proposes to use output data reported to EPA's EDR system.

   Adjustments to Heat Input Data by Fuel Factors

   As in the example allocation methodology in the CAIR SIP model rules, today's proposed approach would include adjustments to heat input by fuel type, using fuel adjustment factors that are based on average historic NOXemissions rates by three fuel types (coal, natural gas, and oil) for the years 1999--2002. These adjustment factors are 1.0 for coal-fired units, 0.6 for oil-fired units, and 0.4 for units fired with all other fuels (e.g., gas). The factors reflect the inherently different emissions rates of different fossil fuel-fired units.

   Modified Output Approach for New Units

   As in the CAIR example allocation approach, the Agency proposes to allocate to new units that have established baselines on a ``modified output'' basis, by multiplying the unit's gross output by a heat rate conversion factor of 7,900 Btu/kWh for coal units and 6,675 Btu/kWh for oil and gas units. A conversion rate for each fuel type will create consistent and level incentives for efficient generation, rather than favoring new units that may have higher heat rates. The conversion factors are based on assumptions in EIA's Annual Energy Outlook (AEO) 2004.

   Cogeneration Units

   As in the CAIR SIP example methodology, for new cogeneration units, allowances would be calculated by converting the available thermal output (Btu) of useable steam from a boiler to an equivalent heat input by dividing the total thermal output (Btu) by a general boiler/heat exchanger efficiency of 80 percent.

   For new combustion turbine cogeneration units, allowances would be calculated by converting the available thermal output of useable steam from a heat recovery steam generator (HRSG) to an equivalent heat input by dividing the total thermal output (Btu) by the same efficiency rate, then adding the electrical generation from the combustion turbine converted to an equivalent heat input by multiplying by the conversion factor of 3,413 Btu/kWh. This sum will yield the total equivalent heat input for the cogeneration unit. This approach focuses on the efficiency of a cogeneration unit in capturing energy in the form of steam or heat from the fuel input.

   For additional discussion of the example NOXallocation methodology in the CAIR SIP model trading rules, see section VIII.D. in the CAIR NFR preamble (70 FR 25278-25282).

   Alternative allocation approach on which the Agency seeks comment: Providing sources owned by small entities with a greater share of allowances.

   The EPA also seeks comment on allocating in such a way as to provide sources owned by small entities with a greater share of allowances. The Agency convened a Small Business Advocacy Review Panel that discussed options to provide additional flexibility to small entities. Specifically, the Agency is taking comment on an option (proposed by one member of the Panel) that would set aside some percentage of States' annual NOXbudgets and provide these allowances to certain small entity sources that can demonstrate economic hardship as a result of the rule. Such an option would necessitate adjusting the number of NOXallowances available to other affected sources in order to ensure that the overall reduction requirements of CAIR are achieved. Because EPA does not allocate SO2allowances, the Agency could only provide relief through NOXallowance allocations. However, because allowances are fungible, it would be possible for the burden on small entity sources that would experience hardship as a result of the SO2 trading program to be reduced through the distribution of additional NOXallowances. The EPA solicits comments on appropriate criteria for establishing hardship. See section 9.4 of the Panel report (http://www.epa.gov/sbrefa) and section IX.C. in this preamble for

   further description of the Panel discussions.

   Alternative allocation approach on which the Agency seeks comment: Use of an auction to distribute NOX allowances.

   Allowances can be distributed by allocating them directly to sources, offering them for sale to bidders (i.e., an ``auction'') or a combination of the two. Today's notice proposes to allocate NOXallowances directly to emissions sources. However, the Agency also seeks comment on the desirability of using a combination of direct allocations and auctions for distributing allowances in the proposed Federal CAIR trading programs. The primary benefit of allowance auctions is that they are the most economically efficient way to distribute allowances. This approach can ensure that all parties, including the general public, have access to allowances. With an auction, existing and new sources have equal access to allowances. Under a combination approach, such as the one we are taking comment on, the effect of these benefits is dependent upon the percentage of allowances that are auctioned.

   The EPA discussed allowance auctions and took comment on using auctions in the CAIR proposal (69 FR 4566, January 30, 2004) and supplemental proposal (69 FR 32684, June 10, 2004). The title IV Acid Rain Program uses a combination approach to distributing allowances, reserving 2.8 percent of available allowances for an auction and directly allocating the remainder.

   The Agency seeks comment on using a combination approach for distributing

   [[Page 49734]]

   NOXallowances in the proposed Federal CAIR trading programs. The proposed approach is analogous to the auction approach in the Administration's proposed Clear Skies legislation, and is defined as follows: For the first CAIR NOXcontrol period (2009) the Agency would allocate 100 percent of the allowances using the fuel- factor adjusted heat input approach described above. For the second control period (2010) the Agency would allocate 99 percent of allowances to units and auction the remaining 1 percent. The percentage of allowances distributed via auction would increase over time, with the Agency distributing via auction an additional 1 percent of allowances every year for twenty years, and then an additional 2.5 percent of allowances every year thereafter, until eventually 100 percent of allowances would be distributed via auction.

   If EPA implemented allowance auctions for the Federal CAIR trading programs, the Agency would establish procedures for the frequency and timing of auctions, bidding schedules and bidding mechanisms, requirements for financial guarantees, and other administrative requirements and procedures as necessary to implement allowance auctions. The Agency seeks comment on appropriate auction procedures for the proposed Federal CAIR trading programs. Allowance auctions are typically (but are not required to be) open to any person, including sources or third-party entities, that can comply with the auction protocols. Proceeds from any auction conducted for Federal CAIR trading programs would be deposited in the United States Treasury.

   Regardless of whether or not the allowance distribution approach taken by the Agency in its Federal trading programs includes the use of auctions, the States have full flexibility in determining the allocation method to use in their State CAIR implementation plans. As discussed above, the EPA would allocate NOXallowances to sources only in a CAIR-State that does not have a timely, approved full CAIR SIP revision or timely, approved abbreviated CAIR SIP revision that includes allocations. A State choosing to submit a full SIP revision or an abbreviated SIP revision that covers allowance allocations could elect to distribute allowances using auctions, direct allocations to sources, or other methodologies (or combinations of methodologies). The Agency intends to withdraw Federal CAIR trading programs in coordination with approval of full CAIR SIP revisions (provisions for withdrawal of CAIR FIPs and section 126 responses are discussed elsewhere in this preamble).

   Allocation of CSP Annual NOXAllowances to Sources

   As discussed in section V, above, the Agency proposes that we will distribute annual NOXallowances from the Compliance Supplement Pools (CSP) to sources for use in complying with the Federal annual NOXcap and trade program. The proposed CSP amounts for each State are the same as in the CAIR NFR, and are shown in Table V-3 in today's action. The Agency is not inviting comment on the State CSP amounts.

   In the CAIR NFR, the Agency provided that a State participating in the EPA-administered CAIR SIP NOXannual trading program would distribute its CSP allowances by two mechanisms: (1) To sources that implement NOXcontrol measures resulting in reductions in 2007 or 2008 that are beyond what is required by any applicable State or Federal emissions limitation (early reductions); and, (2) based on demonstration of need for an extension of the 2009 deadline for implementing emission controls. See section VII.A. in the CAIR NFR preamble (70 FR 25256-25263).

   Today, the Agency proposes to allocate CSP allowances to sources for use in the Federal CAIR annual NOXcap and trade program based on the same two mechanisms as we provided in the CAIR NFR for States to use. However, we propose to use a more specific methodology for determining early reductions than the mechanism provided in the CAIR NFR.

   The Agency proposes to award CSP allowances for early reductions to units that--for the years for which they apply for early reduction credits--are operating at an annual NOXemission rate below 0.25 lb/mmBtu. In addition, the Agency proposes that if a unit applying for early reduction credit is included in a title IV NOX averaging plan, then the source must demonstrate that the plan-wide weighted-average NOXemission rate for the year for which early reduction credit is sought must be equal to or lower than the plan-wide rate for the year prior to the year for which credit is sought. Provided a unit met these proposed criteria, it could request early reduction credit equal to the difference between 0.25 lb/mmBtu and the unit's actual emission rate multiplied by the unit's actual heat input for the applicable control period. In proposing these criteria, for early reductions, EPA believes that the criteria ensure that the award of CSP allowances will be aimed at early reductions and that owners and operators will be able to make reasonable projections about how many allowances they may receive for their early reductions. This early reduction method is similar to the method used in the NOXSIP Call section 126 action (65 FR 2674, January 18, 2000). The Agency seeks comment on this proposed method for determining early reductions.

   Under the abbreviated SIP revision option that the Agency proposes today, States could choose to submit abbreviated revisions addressing distribution of CSP allowances to individual sources. Such revisions would need to include mechanisms based on early reductions as well as based on demonstration of need. States could choose to include the early reduction mechanism set forth in the CAIR SIP model trading rules or could choose to use the more specific early reduction criteria proposed in today's Federal trading rules, in addition to the criterion based on demonstration of need.

5. Allocation of SO2 Emission Allowances to Sources

   The proposed Federal CAIR SO2cap and trade program would rely on title IV allowances, as does the CAIR SIP model SO2trading rule. Title IV allowances have already been allocated in perpetuity to individual units by title IV of the CAA (70 FR 25278). Thus, today's proposal does not include an allocation methodology for SO2allowances, except with regard to opt-in units.

6. Allowance Banking

   Allowance banking is the retention of unused emissions allowances from 1 calendar year for use in a later calendar year. Banking allows sources to make reductions beyond required levels and ``bank'' the unused allowances for use later. Generally speaking, banking has several advantages. Allowance banking can encourage earlier or greater reductions than are required from sources, stimulate the market and encourage efficiency, and provide flexibility in achieving emissions reductions goals.

   The Agency proposes to allow unrestricted banking under the Federal CAIR cap and trade programs, the same as in the CAIR SIP model cap and trade programs. For additional discussion on allowance banking provisions in CAIR, see section VIII.E.1 in the CAIR NFR preamble (70 FR 25282-25283).

7. Incentives for Early Reductions

   When sources reduce their SO2and NOX emissions prior to the first phase

   [[Page 49735]]

   of a multi-phase cap and trade program, it creates a slope of emissions that gradually declines over time, an emission reduction ``glide path'' that provides early environmental benefit and lowers the costs of compliance. Early reduction credits (ERCs) can provide an incentive for sources to install and/or operate controls before the implementation dates. Allowing emission allowances from existing programs to be used for compliance in new programs is another mechanism to encourage early reductions prior to the start of cap and trade programs. See further discussion of this topic in section VIII.F. of the CAIR NFR preamble (70 FR 25284-25286).

   As in the CAIR SIP model trading rules, the proposed Federal CAIR cap and trade programs would provide incentives for early reductions in each of the three programs (the SO2program, NOX program, and ozone season NOXprogram), as described below. 1. SO2Program

   The proposed Federal CAIR SO2cap and trade program would allow for affected sources to use title IV SO2 allowances of vintage 2009 and earlier for compliance with the Federal CAIR program at a 1-to-1 ratio. This approach was part of the CAIR policy case assumptions used in the rulemaking modeling and the EPA has shown that the SO2cap and trade program, with this early incentive mechanism, will achieve the level of SO2 reductions needed to meet the CAIR goals. This proposed early reduction incentive is identical to the SO2incentive in the CAIR SIP model cap and trade programs. 2. NOXProgram

   The proposed Federal CAIR NOXcap and trade program would provide incentives for early annual NOXreductions by creating a Compliance Supplement Pool (CSP) for each affected State, from which EPA could distribute allowances for early, surplus NOXemissions reductions occurring in the years 2007 and 2008, as described above. The Agency's proposed method for allocating CSP allowances to States is explained above. As in the CAIR SIP rule, the CSP for today's proposal would provide a total of about 200,000 annual NOXallowances of vintage 2009 for the CAIR region, apportioned to each State, which would be in addition to each State's annual NOXbudgets. Table V-3 in this preamble provides the CSP amounts by State. The Agency is not inviting comment on the CSP amounts that were determined in CAIR. This proposed early reduction incentive is identical to the annual NOXincentive in the CAIR SIP rule, except that we are proposing a more specific methodology for determining early reductions than the criteria in the CAIR SIP rule. 3. Ozone Season NOXProgram

   The proposed Federal CAIR ozone season NOXcap and trade program would allow the use of NOXSIP Call allowances of vintage years 2008 and earlier for compliance with the Federal CAIR ozone season program. This mechanism would provide an incentive for sources in NOXSIP Call States to reduce their ozone season NOXemissions early and bank additional allowances into the Federal CAIR ozone season program. This proposed early reduction incentive is identical to the ozone season NOXincentive in the CAIR SIP cap and trade programs.

8. Monitoring and Reporting Requirements

   Under the CAIR SIP model cap and trade rules, sources are required to monitor and report NOXand SO2mass emissions in accordance with 40 CFR part 75. (See Section VIII.H. of the CAIR NFR preamble, 70 FR 25288.) Many CAIR sources are measuring and reporting SO2mass emissions and NOXemission rate year round under the Acid Rain Program. Many additional sources are also reporting NOXmass emissions at least during the ozone season and often year round under the NOXSIP Call. The CAIR SIP model rules require continuous measurement of NOXmass emissions by all affected sources by January 1, 2008 using part 75 certified monitoring methodologies for the NOXannual program and May 1, 2008 for the NOXozone season program. SO2emissions must be monitored by those same sources beginning January 1, 2009.

   Today's proposal requires Part 75 monitoring and reporting for all sources subject to the Federal CAIR cap and trade programs. This is consistent with the CAIR SIP model cap and trade programs. For additional discussion on monitoring and reporting requirements, see Section VIII.H. in the CAIR NFR preamble (70 FR 25288).

   I. Differences Between the Proposed Federal CAIR Cap and Trade Programs and the CAIR SIP Rules

   The proposed Federal CAIR NOXand SO2cap and trade programs are largely the same as the CAIR SIP model trading programs. The EPA intends the proposed Federal CAIR cap and trade rules to be as similar as possible to the CAIR SIP model cap and trade rules so that the two sets of rules will operate as single integrated cap and trade programs, one for annual NOX, one for SO2, and one for ozone season NOX. However, the Agency is proposing certain limited differences as described below. These differences arise primarily from the need for Federal implementation of the programs rather than State implementation and to facilitate the transition from Federal implementation to State implementation. Note that the proposed Federal CAIR cap and trade programs include all of the mandatory elements that States must include in order to participate in the EPA-administered cap and trade programs for CAIR (the SIP model trading rules).

   This section describes the main differences between the proposed Federal CAIR trading rules and the CAIR SIP rules. This is not an exhaustive list of differences.

   NOX Allocations

   As discussed above, the proposed NOXallocation methodology for the Federal CAIR annual and ozone season NOX trading programs is consistent with the sample NOX allocation methodology in the CAIR SIP model trading rules. However, timing for recordation of NOXallowances in source accounts differs in the proposed Federal CAIR rules compared to the SIP model rules (see timing discussion, above).

   Additionally, when the Agency allocates NOXallocations, we follow notice and comment procedures consistent with Federal law (the Administrative Procedures Act), whereas under a SIP, a State follows its own administrative procedures (e.g., for notice and comment). Further, the proposed Federal CAIR rules include criteria for ``best available data'' for purposes of NOXallocations (in absence of continuous emission monitoring systems (CEMS) data), which are not included in the SIP model rules.

   Criteria for Allocating CSP Allowances to Sources

   As discussed above, the proposed Federal CAIR rules include a more specific methodology for determining early reductions for purposes of allocating CSP allowances than the mechanism in the CAIR SIP model rules.

   Abbreviated SIP Revisions

   As discussed above, the Agency proposes to give States the option to retain control of certain elements of the Federal CAIR trading programs without submitting full SIP revisions. States could submit abbreviated SIP revisions that cover any of the following four specific elements: (1) Non-EGU opt-ins,

   [[Page 49736]]

   (2) allocation of NOXallowances to individual sources, (3) allocation of annual NOXCompliance Supplement Pool (CSP) allowances to individual sources, and (4) inclusion of non-CAIR NOXSIP Call trading sources in the Federal CAIR ozone season NOXtrading program.

   Applicability

   The EPA intends the applicability provisions specifying units covered by the CAIR Federal trading programs to be identical to those provisions in the CAIR SIP rules. As discussed elsewhere in today's preamble, the Agency is proposing certain changes to the applicability provisions in the CAIR SIP rules. The proposed applicability provisions for the Federal CAIR trading programs are the same as those for the CAIR SIP rules if today's proposed changes to the CAIR SIP rules are finalized.

   Definitions

   The EPA is proposing to use the same definitions as those that apply in the CAIR SIP rules with a few exceptions that are necessary to reflect Federal implementation rather than State implementation.

   Issuance of NOX Allowances Allocations

   The Administrator, rather than the permitting authority, would allocate NOXallowances under the Federal CAIR cap and trade programs, unless an abbreviated SIP revision is approved providing for State allocation of allowances.

   Monitoring and Reporting Requirements

   The proposed Federal CAIR monitoring and reporting provisions (including, among other things, general requirements, initial certification and recertification procedures, out of control periods, notifications, recordkeeping and reporting, and petitions) are essentially the same as the monitoring-related provisions of CAIR SIP model trading rules. The differences between the provisions reflect the fact that the Agency would oversee administration of the monitoring requirements, rather than both the Agency and the permitting authority overseeing the requirements as in the CAIR SIP rules. As a result, for example, monitoring certification applications would be submitted to the Administrator, and the Administrator, rather than the permitting authority, would act on the applications. By further example, the Administrator would handle all audit decertifications and all petitions for alternatives to the monitoring requirements.

10. Coordination Between the Proposed Federal CAIR Cap and Trade Programs and CAIR SIPs

    The EPA intends that if States choose to meet their emission reduction obligations under CAIR by participating in the EPA- administered CAIR SIP NOXand SO2trading programs, such programs will be fully integrated with respective Federal CAIR NOXand SO2trading programs that EPA may promulgate in a final FIP or in a final section 126 response. The sources covered in the CAIR SIP model trading rules are the same types of sources named in the section 126 petition (except that the petition names a subset of the States affected by CAIR) and are the same types as the sources that EPA proposes to regulate in the proposed CAIR FIP and section 126 remedy.

    The SO2allowances under the CAIR SIP SO2 trading program, CAIR FIP SO2trading program, or section 126 SO2trading program would all be termed ``CAIR SO2allowances'' and could be used for compliance with the allowance-holding requirement in any of these trading programs. The NOXannual allowances under the CAIR SIP, CAIR FIP, or section 126 NOXtrading program would all be termed ``CAIR NOXallowances'' and could be used for compliance in any of these trading programs. The NOXozone season allowances under the CAIR SIP or CAIR FIP ozone season NOXtrading program would all be termed ``CAIR Ozone Season NOX allowances'' and could be used for compliance in either of these programs.

    The proposed regulatory text for the CAIR FIP provides that allowances issued under a CAIR FIP or CAIR SIP trading program could be used for compliance in the CAIR FIP trading program (within each of the respective trading programs--SO2, annual NOX, or ozone season NOX). Today's proposal also includes revisions to the CAIR SIP model trading rules that would provide that allowances issued under a CAIR FIP or CAIR SIP trading program could be used for compliance in the CAIR SIP trading program (within the respective SO2, annual NOX, or ozone season NOX trading programs).

    As discussed above, today's proposal does not include regulatory text for the proposed section 126 remedy. If the Agency promulgates regulatory text for the section 126 remedy, the text would include a provision that allowances issued under a CAIR FIP, CAIR SIP, or section 126 trading program could be used for compliance in any of these programs (within the respective emissions trading programs). In that case, the Agency would propose corresponding changes to the CAIR FIP and SIP trading rules to provide that allowances issued under a CAIR FIP, CAIR SIP, or section 126 trading program could be used for compliance in any of these programs.

11. Relationship of Emissions Trading Programs to Section 126 Relief

    In its petition, North Carolina states that ``EPA cannot allow interstate trading of emissions allowances to thwart North Carolina's remedy under section 126.'' Petition p. 25. The State's concern is that under a regionwide trading program, EGUs in upwind States which contribute to North Carolina nonattainment might not in fact reduce their emissions (or might not reduce emissions sufficiently for North Carolina's purposes) since they could purchase allowances from non- contributing (or less-contributing) EGUs. Id. p. 26. North Carolina believes this result to be ``irrational'' because EPA ``would have made the technical finding of contribution without requiring a real remedy''. Id.

    EPA disagrees. As explained above in section II.A., a finding of whether there is a violation of section 126 turns on whether there is a violation of section 110(a)(2)(D), i.e., whether upwind States are contributing significantly to nonattainment or interfering significantly with maintenance in downwind receptors. Upwind States contribute significantly if collective contribution is above a designated amount and highly cost-effective controls are available to reduce emissions. In CAIR, EPA determined the extent of reductions required to eliminate significant contribution (i.e., to remove the section 110(a)(2)(D) violation) and expressed the reductions as statewide budgets of the PM2.5precursors SO2and NOXsusceptible to reduction by highly cost-effective controls. Emissions trading (within the constraints of the emissions caps based on these statewide emission budgets) is one means of implementing highly cost-effective controls and consequently is a lawful (and CAIR-authorized) means of eliminating a section 110(a)(2)(D) violation.

    It therefore follows that once a section 110(a)(2)(D) violation is eliminated, there is no section 126 violation since the basis for the section 126 finding would not exist.\17\ The violation can be

    [[Page 49737]]

    eliminated through EPA adopting a FIP containing the CAIR trading programs or through EPA approving a SIP containing the CAIR trading programs (or approving a SIP containing the other emission reduction options specified in CAIR).

    \17\ Indeed, North Carolina's petition itself essentially recognizes this point, since the petition notes (correctly) that section 110(a)(2)(D) and section 126 are co-extensive for purposes of what constitutes a violation. Id. p. 3. The petition likewise accepts the CAIR definition of ``significant contribution'' and agrees with the statewide emission budgets proposed in CAIR. Id. p. 21.

    For the same reasons, if EPA chooses to act directly under section 126 by making the section 126(b) findings and adopting a remedy pursuant to section 126(c) (rather than eliminating the section 110(a)(2)(D) violation by means of a FIP), EPA could ``bring about compliance with the requirements contained in section [110(a)(2)(D)]'' (CAA section 126(c)) by adopting the CAIR FIP trading programs, for the States containing sources linked to North Carolina PM2.5 NAAQS nonattainment or maintenance problems. This result necessarily follows because, as just explained, these CAIR FIP provisions eliminate the significant contribution to North Carolina nonattainment and maintenance of the PM2.5NAAQS.

    In any event, the Agency believes that upwind sources in States that were found to contribute significantly to North Carolina nonattainment will in fact reduce emissions of PM2.5 precursors under the CAIR trading regime. The Agency used the Integrated Planning Model (IPM) to project emission and cost impacts of CAIR.\18\ The EPA modeled the CAIR requirements assuming interstate emissions trading programs for EGUs. We modeled three separate regionwide EGU emissions trading programs (an annual SO2 program, an annual NOXprogram, and an ozone season NOXprogram). The Agency's IPM modeling for the CAIR NFR-- which assumes interstate emissions trading \19\--projects decreases in annual SO2and NOXemissions under CAIR compared to the Base Case (without CAIR) in both 2010 and 2015 for each of the States found in the CAIR NFR analysis to contribute significantly to nonattainment of the PM2.5NAAQS in North Carolina.\20\

    Moreover, the emission reductions under CAIR are likely to be sufficient to eliminate PM2.5nonattainment in North Carolina. In the CAIR NFR, the Agency presented its modeling of the Base Case, which projects that 10 States would contribute significantly to PM2.5nonattainment in North Carolina in 2010 without CAIR (see discussion in section III in this preamble). Under CAIR, however, EPA's modeling projects that by 2010 there will be no remaining PM2.5nonattainment counties in North Carolina, thus no States contributing to nonattainment. These projected CAIR impacts are likewise from EPA's CAIR modeling with interstate emissions trading.

    \18\ See discussion of EPA's modeling using IPM in section V in this preamble. For further description, see section IV in the CAIR NFR preamble (70 FR 25196-25197) as well as a technical support document entitled ``Modeling of Control Costs, Emissions, and Control Retrofits for Cost Effectiveness and Feasibility Analyses'' in the CAIR docket.

    \19\ The IPM projects plant-level SO2and NOXemissions under interstate emissions cap and trade programs. Emissions trading allows sources to find the least cost compliance strategy.

    \20\ The CAIR annual NOXprogram includes a compliance supplement pool of about 200,000 allowances for the entire CAIR region, the use of which could lead to slightly higher NOXemissions in some CAIR States than the projections shown in the CAIR NFR.

    This discussion of the Agency's analysis of CAIR is informational and is not intended to reopen or reconsider any issue related to that analysis.

    Air quality modeling results are in the Air Quality Modeling Technical Support Document for the Final Clean Air Interstate Rule, March 2005, Appendix F. The EGU emissions modeling for the CAIR NFR is in the CAIR docket. State-by-State summaries of projected emissions impacts of CAIR are on the CAIR Web site at epa.gov/cair/where.html.

    L. Interactions With Other CAA Programs

    In the CAIR NFR preamble, section IX discusses interactions between the NOXSIP Call and CAIR. Section IX also discusses interactions between the title IV Acid Rain Program and CAIR. Today's proposal covers the same States as the CAIR (this proposal includes Delaware and New Jersey for PM2.5purposes which is consistent with EPA's proposal at 70 FR 25408) and uses Federal trading programs that are substantively identical to the CAIR SIP model trading rules, thus the interactions would be as described in CAIR (70 FR 25289-25299).

    VII. What Are the Revisions to the CAIR?

    In today's action, EPA is proposing a number of revisions to the regulations issued as part of the CAIR. The proposed revisions to CAIR, explained in greater detail below, are primarily intended to facilitate federal implementation of the CAIR and to facilitate interaction between the proposed EPA-administered Federal CAIR trading programs and any EPA-administered State CAIR trading programs established through an approved SIP revision to meet the requirements of the CAIR.

    With regard to Sec. 51.123 in the CAIR, EPA is proposing to add provisions that allow states to submit abbreviated SIP revisions--as discussed above in Sections IV and VI of this preamble--that would have to meet certain requirements and that, if approved, would be integrated with the FIP trading programs and replace portions of the programs or modify application of the programs to sources in the State. In particular, a State could submit an abbreviated SIP revision providing for the permitting authority (instead of the Administrator) to allocate CAIR NOXallowances in the Federal CAIR NOX Annual Trading Program. The abbreviated SIP revision could also provide for the permitting authority to allocate the compliance supplement pool in the Federal CAIR NOXAnnual Trading Program. Similarly, the State could submit an abbreviated SIP revision providing for the expansion of the applicability provisions of the Federal CAIR NOXOzone Season Trading Program to include all units in the State's NOXBudget Trading Program that are not already covered by such applicability provisions. The abbreviated SIP revisions could also provide for the permitting authority to allocate CAIR NOXOzone Season allowances under the Federal CAIR NOXOzone Season Trading Program. The abbreviated SIP revision could also provide for the inclusion of non-EGU opt-ins in the Federal CAIR trading programs. These changes will facilitate transfer from an EPA-administered Federal CAIR trading program to any EPA- administered State CAIR trading program.

    Also, included in today's proposal are corresponding provisions in the Federal CAIR trading program regulations that would modify the allocation or applicability sections to be consistent with such approved abbreviated SIP revisions under Sec. 51.123. For example, the Federal CAIR NOXAnnual Trading Program provides that, if an abbreviated SIP revision setting forth procedures for allowance allocations by the permitting authority is approved, the provisions in that SIP revision would replace the provisions otherwise in effect in that trading program for allowance allocation by the Administrator. By further example, the Federal CAIR NOXOzone Season Trading Program provides that, if an abbreviated SIP revision setting forth expanded applicability provisions to include NOXBudget units not already in CAIR is approved, the applicability provisions in the trading program would be

    [[Page 49738]]

    expanded to include such units. These changes will also facilitate transfer from a Federal CAIR trading program to a State CAIR trading program.

    In addition to the proposed revisions to Sec. 51.123 providing for abbreviated SIP revisions, today's action proposes other revisions to both Sec. 51.123 and Sec. 51.124 in order to clarify the definition of ``EGU'' in those rules. In particular, as discussed above in Section VI of the preamble, the status of solid waste incinerators under the CAIR is unclear. EPA did not intend for CAIR to require States that elect to participate in the EPA-administered CAIR trading program to regulate solid waste incineration units. In addition, the CAIR FIP is not intended to directly regulate solid waste incineration units. Furthermore, EPA has received two petitions to reconsider the definition of EGU with respect to solid waste incinerators in the model trading rule. The petitions were submitted by the Integrated Waste Service Association (IWSA) and the Commonwealth of Massachusetts.\21\ In its petition, IWSA presents two main arguments regarding why EPA should reconsider the treatment of solid waste incinerators (and particularly municipal waste incinerators) under CAIR. First, it indicates that EPA failed to take notice and comment on the treatment of municipal waste incinerators (MWCs) under CAIR. The Commonwealth of Massachusetts makes a similar argument Second, IWSA argues that ``the regulation of MWCs is contrary to the core EPA methodology for regulating interstate transport of emissions under CAIR.'' As part of the second argument, IWSA makes two main points. They argue that emission reductions from municipal waste units are not highly cost effective and they argue that emissions of SO2and NOXfrom municipal waste combustors are very small. The Commonwealth of Massachusetts also argues that EPA did not perform any specific cost analysis on municipal waste combustors to determine whether emission reductions from this source category were highly cost effective.

    \21\ The petitions, as well as the letters granting reconsideration of the petitions, will be available in the docket for the CAIR (OAR-2003-0053).

    EPA has granted reconsideration on the issue of the definition of EGU in the final CAIR model trading rule as it relates to solid waste incinerators (and particularly municipal waste incinerators) because EPA agrees, that its analysis of highly cost effective emissions reductions did not assume that emissions from municipal waste combustors were highly cost effective to control. Further, EPA did not specifically indicate that it intended solid waste incinerators to be included in the model trading program. In fact, in both the proposed and final actions, EPA indicated that it did not consider reductions from municipal waste combustors in its determination of highly cost effective emission reductions. In a January 2004, technical support document entitled ``Identification and Discussion of Sources of Regional Point Source NOXand SO2Emissions other than EGUs'', EPA indicated that, ``In examining non-EGU categories for emission reduction opportunities, we identified categories emitting more than one percent of the overall projected SO2or NOXyear 2010 emission inventory for the geographic area of interest.'' The document also notes that SO2emissions from waste incinerators emit about 0.1 percent of the SO2, and 0.7 percent of the NOX. In the response to comments document for the final rule, EPA indicated that, ``the final rule, as was the case for the proposal, does not reflect any emission reductions for NOXor SO2from MWC facilities.'' For this reason, EPA decided to grant the petitions to reconsider this issue. It is therefore unnecessary for EPA to consider the other arguments presented by petitioners.

    In this rulemaking EPA is reconsidering the definition of EGU in the final CAIR as it relates to MWCs and is taking comment on that issue. EPA is not taking comment on other issues not being reconsidered or addressed in this rulemaking--including the determination that, for purposes of the CAIR rulemaking, EPA did not determine that there were highly cost effective emission reductions from MWCs. It should also be noted that excluding MWCs from the definition of EGU in the CAIR model trading rule, does not preclude States from regulating MWCs, or other non-EGU sources, for the purpose of obtaining emission reductions required by CAIR.

    The proposed revisions of the ``EGU'' definition address these issues. The proposed revisions would establish a specific exemption for certain solid waste incineration units. The proposed exemption is analogous to an exemption for such units under the Acid Rain Program. In addition, the status, under the CAIR, of units that formerly generated electricity for sale but stopped doing so many years ago warrants further clarification. The proposed revisions to the ``EGU'' definition state that, in order to be an EGU, a unit must serve a generator producing electricity for sale at any time since the later of November 15, 1990 or the start-up of the unit's combustion chamber. This proposed approach is analogous to the approach under the Acid Rain Program. This proposed approach also makes consistent EPA's position on this issue in the CAIR and the CAIR FIP proposed today.

    Today's action also includes proposed revisions to the regulations setting forth the CAIR model trading programs. There are three categories of revisions. The first category includes revisions to clarify certain aspects of the CAIR model trading programs. This category of changes primarily intends to ensure consistency between the CAIR model trading rules and the proposed Federal CAIR trading programs. For example, revisions, analogous to the proposed revisions to the ``EGU'' definition in Sec. Sec. 51.123 and 51.124, are proposed for the applicability provisions of the CAIR model trading programs to exclude certain solid waste incineration units and certain units that stopped before November 15, 1990, and do not resume, serving a greater- than-25 MW generator producing electricity for sale. Further, the definitions of some terms in the CAIR model trading programs (``commence commercial operation'' and ``commence operation'') are also revised consistent with the exclusion of units that, before November 15, 1990, stopped serving a greater-than-25MW generator producing electricity for sale. These revisions make the CAIR model trading rules consistent with the proposed applicability provisions and definitions for the Federal CAIR trading programs.

    Another set of revisions are proposed to clarify the interaction of the application of excess emission penalties for sources that are subject to, and have excess emissions under, both the Acid Rain Program and the CAIR SO2trading program. Under the existing CAIR SO2model trading rule, the Administrator first determines, for a source in both the Acid Rain Program and the CAIR SO2 trading program, whether the source holds enough allowances to cover emissions under the Acid Rain Program and then whether the source holds enough allowances to cover emissions under the CAIR SO2 trading program. To the extent a source fails to hold enough allowances and so has excess emissions under the Acid Rain Program, the owners and operators must provide the Administrator one allowance from the next year to offset each ton of excess emissions and pay a $2,000 inflation- adjusted penalty per ton of excess emissions. To the extent the source also fails to hold enough allowances and so has excess emissions under the CAIR

    [[Page 49739]]

    SO2trading program, the owners and operators must provide a tonnage equivalent of allowances equaling 3 times (including a one-for- one offset) the tonnage of the excess emissions. As a result, the owners and operators may be liable, for a given ton of excess emissions, for both the offset and dollar penalty under the Acid Rain Program and the three-for-one allowance deduction.

    Under the proposed revisions, for a given ton of SO2 excess emissions at a source, the owners and operators will be liable for either the offset and dollar penalty under the Acid Rain Program or the three-for-one allowance deduction under the CAIR trading program. EPA believes that the Acid Rain dollar penalty, which is currently about $3,000 per ton of excess emissions (due to the inflation adjustment of the original $2,000 per ton penalty) is sufficiently large to provide a strong incentive for compliance with the allowance- holding requirement with regard to any tons of excess emissions under the Acid Rain Program. Under the proposal, any tons of excess emissions that a source under both the Acid Rain and CAIR trading programs has beyond the Acid Rain Program excess emissions would be subject to the three-for-one allowance deduction under the CAIR trading program. The EPA maintains that it is unnecessary to apply to a given ton of excess emissions both the Acid Rain and CAIR trading program penalties. The EPA also notes that the proposed revisions would address only the automatic penalties under the two programs and would not affect in any way the ability to impose, through enforcement actions, additional discretionary civil or criminal penalties.

    The second category of revisions to the CAIR model trading rules includes those necessary to integrate the State CAIR trading programs with the appropriate Federal CAIR trading programs. As discussed above in Section VI of the preamble, EPA's intention is that the State CAIR trading programs for those States with approved SIP revisions and the Federal CAIR trading programs for those States without approved SIP revisions (or with only approved abbreviated SIP revisions) would all operate together as integrated trading programs, one integrated program covering NOXannual emissions, one covering SO2 annual emissions, and one covering NOXozone season emissions. Certain revisions to the CAIR model trading programs (and certain analogous provisions in the Federal CAIR trading programs) are necessary to accomplish this integration. For example, the definition of ``CAIR NOXallowance'' is revised in order to ensure that NOXallowances issued in a Federal CAIR NOX annual trading program are treated the same in the State CAIR NOXannual trading program as (and so is interchangeable with) NOXallowances issued in the latter program. The definitions of ``CAIR SO2allowance'' and ``CAIR NOXOzone Season allowance'' are similarly revised.

    The third category of revisions includes minor corrections of the CAIR model trading program regulations. These changes are intended to facilitate federal implementation of the CAIR and ensure consistency between State CAIR trading programs and the Federal CAIR trading programs by removing ambiguities in the CAIR. For example, certain provisions of the current CAIR SO2model trading rule reference non-existent provisions about SO2allowance allocations. EPA is proposing to remove the provisions that include these references.

    By further example, the CAIR NOXmodel trading rule requires the Administrator to record allocations submitted by the States for 2009 by December 1, 2006. However, since the SIP revisions that include such allocations are not due until September 11, 2006, it is highly unlikely that the SIP revisions will be approved by EPA in time for the allocations to be recorded by December 1, 2006. CAIR NOXallowance allocations should not be recorded, and thereby be tradable in the allowance market, before the SIP revision on which the allocations are based is final. It would be highly disruptive to the allowance market if allocations that could be recorded and traded could subsequently be rendered invalid due to disapproval of the SIP revision on which the allocations are based. For this reason, EPA is proposing to remove the deadline for recordation of the allocations for existing units for the first set of years submitted in the SIP revision, but to retain the deadlines for recordation for the subsequent allocations.

    VIII. What Are the Revisions to the Acid Rain Program?

    EPA is also proposing in today's action a few revisions to the Acid Rain Program regulations. Most of the proposed revisions are changes to the administrative appeal procedures in part 78 of the Acid Rain Program regulations in order to make those procedures applicable to all final decisions of the Administrator under the Federal CAIR trading programs. In the CAIR, part 78 was revised to make those administrative appeal procedures apply to the Administrator's final decisions under the State CAIR trading programs. The part 78 revisions in today's proposal are analogous to those revisions made in the CAIR and are necessary to provide consistent appeal procedures to sources subject to the CAIR FIP.

    The remaining provisions aim to facilitate interaction between the EPA-administered Federal CAIR trading programs, any EPA-administered State CAIR trading programs, and the Acid Rain Program. A number of these proposed revisions involve minor changes to language in some certifications included in the certificate of representation for designated representatives and in some certifications by authorized account representatives for general accounts. Analogous minor revisions are proposed for provisions describing the relationship of the designated representative to the owners or operators of the sources and units represented and of the authorized account representative to the owners of the allowances in the general account involved. The purpose of these proposed revisions is to make the wording of these Acid Rain Program provisions and certifications essentially the same as the analogous provisions and certifications in the State and Federal CAIR trading programs in order to streamline the requirements and the forms that must be submitted. Many sources are likely to be subject to both the Acid Rain Program and the CAIR trading programs.

    Some of the proposed revisions are related to the change, finalized in the CAIR rulemaking, from unit-level to source-level compliance with the Acid Rain Program SO2trading program. For example, EPA is proposing to remove a provision that allows two designated representatives for the same source under certain circumstances. While it was workable to have one designated representative for one, non-opt- in unit at the source and a different designated representative for another, opt-in unit at the same source where compliance with the allowance-holding requirement was achieved unit-by-unit, this is not workable where compliance is at the source-level and one individual must be responsible for compliance by all units at the source.

    IX. Statutory and Executive Order Reviews

1. Executive Order 12866: Regulatory Planning and Review

   Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Agency

   [[Page 49740]]

   must determine whether a regulatory action is ``significant'' and therefore subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The Order defines ``significant regulatory action'' as one that is likely to result in a rule that may:

   1. Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or Tribal governments or communities;

   2. Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

   3. Materially alter the budgetary impact of entitlements, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

   4. Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

   In view of its important policy implications and potential effect on the economy of over $100 million, this action has been judged to be an economically ``significant regulatory action'' within the meaning of the Executive Order. As a result, today's action was submitted to OMB for review. The FIP proposal represents a federal mandate to implement the recently published CAIR (March 2005) covering the same set of air pollution emission reductions in the event States fail to implement CAIR. The section 126 proposal would impose regulatory requirements similar to CAIR in the States that significantly contribute to downwind emissions in North Carolina. For this reason, EPA is relying on the economic analysis conducted for CAIR entitled ``Regulatory Impact Analysis of the Final Clean Air Interstate Rule'' (March 2005) to serve as the analysis for these rulemakings. The costs and benefits presented in this economic analysis are an accurate representation of the benefits and costs of the FIP. The benefits and costs of the section 126 action would be a subset of the benefits and costs associated with CAIR, because only a subset of CAIR-affected States would be affected.

2. Paperwork Reduction Act

   EPA believes that the Paperwork Reduction Act (44 U.S.C. 3501 et seq.) requirements of this rule are satisfied through the Information Collection Request (ICR) (EPA ICR number 2152.02) submitted to the OMB for review and approval on May 12, 2005 as part of the Clean Air Interstate Rule (CAIR) (70 FR25162-25405). The ICR describes the nature of the information collection and its estimated burden and cost associated with that final rule. In cases where information is already collected by a related program, the ICR takes into account only the additional burden. (This situation arises in States that are also subject to requirements of the Consolidated Emissions Reporting Rule (EPA ICR number 0916.10; OMB control number 2060-0088) or for sources that are subject to the Acid Rain Program (EPA ICR number 1633.13; OMB control number 2060-0258) or NOXSIP Call (EPA ICR number 1857.03; OMB number 2060-0445) requirements.)

   The burden of today's proposed rule is essentially the same as the burden estimated for the CAIR. There is a modest transfer of burden from the States to EPA if the federal plan is implemented rather than the CAIR State plan. The overall total burden is essentially unchanged.

   An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations in 40 CFR, after appearing in the preamble of the final rule, are listed in 40 CFR part 9.

3. Regulatory Flexibility Act

   The Regulatory Flexibility Act (RFA), as amended by the Small Business Regulatory Enforcement Fairness Act (SBREFA), generally requires an agency to prepare a regulatory flexibility analysis for any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute, unless the agency certifies that the proposed rule, if promulgated, will not have ``a significant economic impact on a substantial number of small entities.'' Small entities include small businesses, small organizations and small governmental jurisdictions.

   For the purposes of this rulemaking, EPA defined small entities according to the following three criteria:

   (1) A small business according to the Small Business Administration size standards by the North American Industry Classification System (NAICS) category of the owning entity. The range of small business size standards for electric utilities is 4 billion kilowatt-hours of production or less;

   (2) a small government jurisdiction that is a government of a city, county, town, district, or special district with a population of less than 50,000; and

   (3) a small organization that is any not-for-profit enterprise that is independently owned and operated and is not dominant in its field.

   Table IX-1 lists entities potentially affected by this proposed rule with applicable NAICS code.

   As required by section 609(b) of the RFA, as amended by SBREFA, EPA convened a Small Business Advocacy Review Panel (SBAR Panel or Panel) and conducted outreach to small entities representatives (SERs) to obtain the advice and recommendations of small entities that potentially would be subject to the rule's requirements.

   On April 27, 2005, EPA's Small Business Advocacy chairperson convened a SBAR Panel under section

   [[Page 49741]]

   609(b) of the RFA, as amended by SBREFA. For this proposal, in addition to the EPA Small Business Advocacy chairperson, the Panel consisted of EPA's Director of Air Quality Strategies and Standards Division within the Office of Air and Radiation, the Administrator of the Office of Information and Regulatory Affairs within the Office of Management and Budget (OMB), and the Chief Counsel for Advocacy of Small Business Administration (SBA).

   As described below, this Panel conducted outreach to SERs and completed a report on this proposed action. The Panel Report provides background information on the proposal as it was being developed and the types of small entities that may be subject to the proposal, describes efforts to obtain the advice and recommendations of representatives of those small entities, summarizes the comments that have been received to date from those representatives, and presents the findings and recommendations of the Panel. The Panel Report, written comments from the SERs, the Initial Regulatory Flexibility Analysis (discussed below), and other information are contained in the docket for this rulemaking. The Panel Report is also available on the EPA's Web site at http://www.epa.gov/sbrefa. It is important to note that the

   Panel's findings and discussions are based on the information available at the time the Panel Report was drafted.

   Prior to convening the SBAR Panel, EPA had several discussions and a conference call with small entities that could be affected by this rule. In consultation with SBA, EPA invited 16 stakeholders to participate in its outreach efforts on this proposal. On April 4, 2005, EPA held conference call with the potential SERs and invited representatives from the Office of Advocacy of the SBA and the Office of Information and Regulatory Affairs within the OMB to the call. During this call, EPA presented an overview of the SBREFA process, an explanation of the planned CAIR FIP and Section 126 rulemaking, and technical background on such information as control options and costs. Subsequent to the meeting, the stakeholders submitted follow-up comments in writing.

   On May 5, 2005, the SBAR Panel invited the SERs to an outreach meeting and provided them with additional background information for their consideration. These materials included the previously provided background on the potential action and pollutants of interest, as well as information the relevant States and further technical and economic information about affected entities. The outreach meeting occurred on May 24, 2005, followed by written comments from some of the SERs. Written comments were summarized in the Panel Report and can be found in the docket.

   The SBAR Panel considered the oral and written comments of the SERs in preparing the final Panel Report discussed above. The primary topic of the Panel discussion was the applicability of the FIP to the various categories of small entity-owned EGUs, the costs the proposal could potentially impose, and the advantages and disadvantages of implementing any of four regulatory flexibility alternatives. Additional topics included monitoring and reporting provisions and overlap with existing federal rules.

   The SBAR Panel process for today's action was conducted before the proposed proposal was fully drafted. The Panel holds its discussions and makes its report at a preliminary stage of the rule development. The Panel discussions and report provide the Agency with an opportunity to identify and explore potential ways of shaping the proposal to minimize the burden of the proposal on small entities while achieving the purpose of the proposed action.

   The SBAR Panel discussions for this proposal focused on the objectives and general outline of the CAIR FIP and Section 126 Response. The EPA also explained to the Panel that the proposal would be very similar to the CAIR model trading rules and provided the Panel with analyses that were conducted for CAIR. The Panel considered that the proposal would need to obtain the same emission reductions as would be achieved under CAIR and that the proposal would be designed to work in concert with the CAIR trading rules.

   The action proposed today includes certain revisions to the Acid Rain Program and the final CAIR proposed in conjunction with the CAIR FIP and section 126 response. These revisions are intended to facilitate federal implementation of the CAIR, and address the interaction between the proposed EPA-administered federal CAIR trading program and any EPA-administered State CAIR trading programs. These revisions support the CAIR FIP and the 126 response extensively discussed by the Panel and are explained in greater detail in sections VII and VIII above.

   To the extent that the Panel Report or the initial regulatory flexibility analysis for today's proposal address any proposed changes to the CAIR, EPA notes that courts have interpreted the RFA to require a regulatory flexibility analysis only when small entities will be subject to the requirements of the rule. See Michigan v. EPA, 213 F.3d 663, 668-69 (D.C. Cir., 2000), cert. den. 121 S.Ct. 225, 149 L.Ed.2d 135 (2001). The proposed revisions to the CAIR would not establish requirements directly applicable to small entities and, like the CAIR (70 FR at 25420), do not require a regulatory flexibility analysis. 2. Initial Regulatory Flexibility Analysis

   Pursuant to section 603 of the RFA, EPA prepared an initial regulatory flexibility analysis (IRFA) that examines the impact of this proposal on small entities along with regulatory alternatives that could reduce that impact. The IRFA is available for review in the docket for today's rulemaking and is summarized in the sections below. a. Background on Today's Proposal and the IRFA

   This action proposes Federal Implementation Plans (FIPs) for all States affected by the Clean Air Interstate Rule (CAIR). The FIPs would serve as a backstop measure to achieve the emission reductions requirements established by the CAIR until States have approved State implementation plans (SIPs) to achieve the reductions. The Agency's authority to promulgate FIPs is contained in section 110 of the CAA.

   This action also proposes EPA's response to a petition submitted by the State of North Carolina under section 126 of the CAA. The EPA is proposing Federal cap and trade programs for electric generation units (EGUs) as the control strategy for the FIPs as well as the section 126 action. The proposed Federal cap and trade programs are virtually identical to the CAIR model trading rules.

   The EPA is also proposing certain revisions to the CAIR and the Acid Rain Program. Sections I through IV in today's preamble explain in more detail the reasons the Agency is considering this action, as well as the Agency's objectives and the legal basis for the proposed action.

   The CAIR does not establish specific requirements applicable to small entities. Instead, the CAIR requires states to develop, adopt and submit SIP revisions that will achieve the necessary SO2and NOXreductions, leaving to states the task of determining how and by which entities these reductions will be obtained. Although not required by the RFA, EPA conducted an analysis of the impact of regulations implementing the CAIR model trading rules on small

   [[Page 49742]]

   entities. The Federal cap and trade programs in today's proposal are virtually identical to the CAIR model trading rules. For the small entity analysis conducted for CAIR we analyzed the potential impacts that regulations implementing the model trading rules in the CAIR might have on small entities. EPA expects the impacts of the CAIR FIP trading programs in today's proposal to be identical to the impacts we analyzed for regulations implementing the model trading rules in the CAIR. Therefore, the small entity analysis that the Agency conducted for CAIR rulemaking provides the basis for the IRFA for today's proposal. The CAIR small entity analysis is contained in chapter 8 of the Regulatory Impact Analysis for the Final Clean Air Interstate Rule, March 2005, available in the docket for the CAIR rulemaking. b. Potentially Affected Small Entities

   Approximately 140 of the estimated 3,000 EGUs potentially affected by today's action are owned by the 58 potentially affected small entities identified by EPA. Of the 140, 49 units are owned by small entities that also share ownership with large entities. Of these units, 34 are believed to be more than 50 percent owned by a large entity. An additional 189 units owned by small entities in these states could be exempted because they have a nameplate capacity less than 25 MW. The above estimates include a number of units that are owned jointly by small and non-small entities. In addition, these estimates represent the maximum number of units potentially affected by the CAIR FIP. Only units in states that fail to submit an approved SIP would be directly regulated under the CAIR FIP. The actual number of affected units will depend on the number of states that do not submit a SIP or do not get their SIP submittal approved. c. Impact on Potentially Affected Small Entities

   EPA has assessed the potential impact of today's action on small entities. This analysis is based in large part on EPA's prior analysis of the potential impact of regulations implementing the CAIR model trading programs in the CAIR region. The analysis of the model trading programs was based on the best information available at that time and assumed that 75 small entities could be affected by any eventual implementation of the trading programs. However, EPA subsequently determined that some of these 75 entities either did not meet the definition of a small entity, or had units that were no longer generating. EPA's final analysis thus concluded that only 58 entities would be affected by today's action. Because the Agency's analysis of small entity impacts was based on the earlier estimate of affected small entities (i.e., the impacts were analyzed based on 75 affected entities not 58 entities), the impact analysis would overstate the maximum potential impact of today's action on small entities.

   Overall, EPA analysis suggested that about 445 MW of total small entity capacity, or 1.0 percent of total small entity capacity in the CAIR region, is projected to be uneconomic to maintain under regulations implementing the CAIR trading programs relative to the Base Case. In practice, units projected to be uneconomic to maintain may be ``mothballed'', retired, or kept in service to ensure transmission reliability in certain parts of the grid. Our IPM modeling is unable to distinguish between these potential outcomes.

   Of the 75 initially identified as potentially impacted by regulations implementing the model trading programs, EPA determined that 29 might experience compliance costs in excess of one percent of revenues in 2010 and 46 might in 2015. Potentially affected small entities experiencing compliance costs in excess of 1 percent of revenues have some potential for significant impact resulting from implementation of CAIR.

   Moreover, the decision to include only units greater than 25 MW in size exempts 185 small entities that would otherwise be potentially affected by today's actions. In the final CAIR, EPA stated its belief that it is reasonable to assume no further control of air emissions from these smaller EGUs. Available air emissions data indicate that the collective emissions from small EGUs with capacity less than or equal to 25 MW are relatively small and that further regulating their emissions would be burdensome, to both the regulated community and regulators, given the relatively large number of units. In addition, the use of cap and trade in general will limit impacts on small entities relative to a less flexible command-and-control program.

   EPA considered several additional suggestions raised during the SBAR panel process that would have changed the scope, and thus the impact, of today's action. One SER suggested exempting small gas turbines from the rule. The Panel did not recommend exempting small gas turbines from the program. The Panel believed that the reduced monitoring requirements for this set of sources under CAIR will provide a significant level of relief to these sources, which are low emitters of both NOXand SO2. According to EPA analysis, most of these sources are projected to be net sellers of allowances, and the maximum impact projected for any one of these sources in terms of the ratio of costs to electricity generation revenues is approximately 3 percent. Additionally, today's action does exempt a number of small gas turbines as a result of the 25 MW and below exemption. The SBAR Panel supported retaining this exemption in today's action. d. Potential Reporting, Record Keeping, and Compliance Requirements

   EPA also considered suggestions from the SBAR Panel regarding reporting and recordkeeping requirements of the proposed action. During the outreach to the SERs, one SER noted that EPA should coordinate emissions monitoring reporting among this and other related rules as much as possible. EPA has developed emission monitoring and reporting provisions intended to minimize the burden of reporting requirements on sources. Sources will submit one quarterly report that will account for emissions under any of the following programs that they are subject to: Title IV SO2and/or NOX, Federal CAIR SO2, annual NOXand/or ozone season NOX. Finally, as part of the FIP development process, EPA has coordinated FIP and SIP requirements as much as possible to minimize any conflicts in requirements that could occur if a State submitted a SIP that was approved by EPA and replaced the Federal CAIR trading rules. e. Relevant Federal Rules

   There are four Federal rules that may cover the same types of sources and pollutants as those covered in this proposal: The Clean Air Interstate Rule (CAIR), Regional Haze Rule, Acid Rain Program, and the NOXSIP Call. During development of this proposal the Agency took great care to ensure that the proposed programs not conflict with other CAA programs. As discussed in detail elsewhere in this preamble, the Agency designed each of the elements of today's proposal--the CAIR FIP, section 126 response, revisions to CAIR and revisions to the Acid Rain Program--to work together. The Agency gave particular emphasis to the interaction between CAIR and the Acid Rain Program, since CAIR relies on the use of Acid Rain Program allowances for SO2, and this feature of the program limits the flexibility of EPA in its design of regulatory flexibility alternatives for the CAIR FIP/126 rules. The Panel did not make specific recommendations in this area. EPA's decision to use the existing

   [[Page 49743]]

   SO2allocation from the Acid Rain Program is explained in greater detail in the preamble to the final CAIR (70 FR 25299). f. Regulatory Flexibility Alternatives

   The SBAR Panel discussed four options to provide additional flexibility to small entities:

   Option 1. An alternative compliance method for units with low emissions, whereby facilities could adopt a voluntary limit on emissions;

   Option 2. An option to buy allowances from EPA at a fixed price, which would protect units from market volatility in the price of allowances;

   Option 3. Provide sources owned by small entities with a greater share of allowances, and;

   Option 4. Recognize and utilize the existing flexibilities within the CAIR model trading rules.

   In considering the four regulatory alternatives, the SBAR Panel evaluated the feasibility of implementing each option, as well as the extent to which the analysis of each option showed effective relief for financially-impacted small entities. Implementation of Options 1, 2, or 3 would require adjusting the number of allowances available to non- small-entity sources, in order to ensure that the overall reduction requirements of CAIR are achieved. As is discussed in Section 3 of the Panel Report, these adjustments could introduce administrative complexity and uncertainty in the case of SO2as to whether the reduction requirement is being met. The Panel also discussed how to set appropriate exemption levels, allowance adjustments, or price levels if EPA were to decide to implement one of the first three alternatives. Additionally, the Panel had to consider how to determine small entities' eligibility for potential relief, as well as treatment of sources that were primarily owned by large entities, but had minority ownership by small entities.

   The SBAR Panel undertook detailed analysis of the four regulatory flexibility alternatives and of the comments and discussion provided by the small entity representatives during the SBAR Panel process. Consensus was not reached as to the final recommendation of the Panel. Two Panel members recommended that EPA pursue Option 4 as the means of providing flexibility to small entities under the proposed CAIR FIP and section 126 action. In general, this was due to the ability of the existing CAIR rule to provide a number of flexibilities to small entity sources, such as ability to trade and bank allowances, the inclusion of a compliance supplement pool for NOX, and reduced monitoring requirements for some small units. In making this recommendation, these two Panel members also considered the possible trade-offs in terms of administrative ease and the ability to target sources that would need effective relief.

   All SBAR Panel members agree that for the great majority of affected small entities, the CAIR model trading rules, or Option 4, provides the appropriate mechanism for limiting economic burdens, by allowing the purchase and sale of allowances in the market by all units. In the view of one Panel member, the Option 3 hardship approach best accommodates the needs of small entities with severe hardships and the burden of administering this added program element, while preserving the identical benefits of the CAIR program. Essentially, this Panel member suggested that EPA could provide meaningful relief to entities expected to experience severe hardship by setting aside some percentage of States' annual NOXbudgets, and providing these allowances to small entity sources that demonstrate the potential for severe economic hardship as a result of the proposed action. Analysis conducted by this Panel member suggested that setting aside approximately 15,000 NOXallowances annually could provide significant relief to entities projected to experience severe hardship as a result of the proposed CAIR FIP and section 126 action.

   The SBAR Panel did not recommend that EPA incorporate Option 1 or Option 2 into the CAIR FIP and section 126 action. Regarding Option 1, the Panel generally agreed that this option would not provide a mechanism for providing relief to many small entity sources. Additionally, EPA noted that this option was made available under the NOXSIP call, and was used very sparsely. The majority of small entity representatives did not express support for this option. Option 2 could be implemented using either a safety valve price for small entity sources that falls below the projected allowance prices, or above projected allowance prices. Given the implementation issues discussed in Section 3 of the Report, and the uncertainty about what type of relief this option might provide, the Panel did not recommend that EPA consider this option further.

   The EPA invites comment on all aspects of the proposal and its impacts on small entities. The EPA is accepting comment only on today's proposal. EPA is not accepting comment on the CAIR or otherwise reopening any issue decided in the CAIR for reconsideration or comment, except that we are taking comment specifically the revisions to the CAIR and the Acid Rain program that EPA is proposing in today's action, as well as on the proposed CAIR FIP, the Section 126 response, and the impacts of these proposals on small entities.

4. Unfunded Mandates Reform Act

   Title II of the Unfunded Mandates Reform Act of 1995, Public Law 104-4, establishes requirements for Federal agencies to assess the effects of their regulatory actions on State, local, and tribal governments and the private sector. Under section 202 of the UMRA, 2 U.S.C. 1532, EPA generally must prepare a written statement, including a cost-benefit analysis, for any proposed or final rule that ``includes any Federal mandate that may result in the expenditure by State, local, and tribal governments, in the aggregate, or by the private sector, of $100,000,000 or more * * * in any one year.'' A ``Federal mandate'' is defined under section 421(6), 2 U.S.C. 658(6), to include a ``Federal intergovernmental mandate'' and a ``Federal private sector mandate.'' A ``Federal intergovernmental mandate,'' in turn, is defined to include a regulation that ``would impose an enforceable duty upon State, local, or tribal governments,'' section 421(5)(A)(i), 2 U.S.C. 658(5)(A)(i), except for, among other things, a duty that is ``a condition of Federal assistance,'' section 421(5)(A)(i)(I). A ``Federal private sector mandate'' includes a regulation that ``would impose an enforceable duty upon the private sector,'' with certain exceptions, section 421(7)(A), 2 U.S.C. 658(7)(A).

   The EPA is taking the position that the requirements of UMRA apply because this action could result in the establishment of enforceable mandates directly applicable to sources (including sources owned by State and local governments) that could result in costs greater than $100 million in any one year. The UMRA generally requires EPA to identify and consider a reasonable number of regulatory alternatives and adopt the least-costly, most cost-effective or least-burdensome alternative that achieves the objectives of the rule.

   EPA is relying upon the government entity analysis prepared for the final CAIR. The actual impacts on government entities of today's action would likely be less than those estimated in the analysis done for the CAIR because fewer States and individual sources are likely to be affected.

   According to EPA's analysis, the total net economic impact on government-

   [[Page 49744]]

   owned entities is expected to be negative in both 2010 and 2015. However, IPM modeling projects that about 340 MW of municipality-owned capacity (about 0.4 percent of all subdivision, State and municipality capacity in the CAIR region) would be uneconomic to maintain under CAIR, beyond what is projected in the Base Case. In practice, units projected to be uneconomic to maintain may be ``mothballed'', retired, or kept in service to ensure transmission reliability in certain parts of the grid. Our IPM modeling is unable to distinguish between these potential outcomes.

   Of the 81 potentially affected government entities considered in EPA's analysis, and the 265 government entities in the CAIR region that are included in EPA modeling, 19 may experience compliance costs in excess of one percent of revenues in 2010, and 38 may in 2015, based on our assumptions of how the affected States implement control measures to meet their emissions budgets as set forth CAIR.

   Government entities projected to experience compliance costs in excess of 1 percent of revenues have some potential for significant impact resulting from implementation of this rulemaking. However, the majority of entities facing potentially significant impacts are located in States with regulated electricity markets, where they have the ability to pass some or all of their compliance cost on to ratepayers. In addition, the decision to include only units greater than 25 MW in size exempts 179 government entities that would otherwise be potentially affected by regulations implementing the CAIR trading programs. Finally, the use of cap and trade in general will limit impacts on entities owned by small governments relative to a less flexible command-and-control program.

   Under section 203 of UMRA, 2 U.S.C. 1533, before EPA establishes any regulatory requirements ``that might significantly or uniquely affect small governments,'' EPA must have developed a small government agency plan. The plan must provide for notifying potentially affected small governments; enabling officials of affected small governments to have meaningful and timely input in the development of EPA regulatory proposals with significant Federal intergovernmental mandates; and informing, educating, and advising small governments on compliance with the regulatory requirements. The requirements do not distinguish EGUs based on ownership, either for those units that are included within the scope of the rule or for those units that are exempted by the generating capacity cut-off. Consequently, the rule has no requirements that uniquely affect small governments that own or operate EGUs within the SIP call region. With respect to the significance of the rule's provisions, EPA's UMRA analysis demonstrates that the economic impact of the rule will not significantly affect State or municipal EGUs or non-EGUs, either in terms of total cost incurred and the impact of the costs on revenue, or increased cost of electricity to consumers. Therefore, development of a small government plan under section 203 of the Act is not required.

   During the CAIR rulemaking process, EPA prepared a written statement consistent with the requirements of section 202 of the UMRA. Furthermore, in a manner consistent with the intergovernmental consultation provisions of section 204 of the UMRA, EPA carried out consultations with the governmental entities potentially affected by this rule during the CAIR rulemaking process.

5. Executive Order 13132: Federalism

   Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 1999), requires EPA to develop an accountable process to ensure ``meaningful and timely input by State and local officials in the development of regulatory policies that have federalism implications.'' ``Policies that have federalism implications'' is defined in the Executive Order to include regulations that have ``substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.''

   This proposed rule does not have federalism implications. It would not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government, as specified in Executive Order 13132. These effects would not occur from the final rule itself because it is the provisions of the CAA that require EPA, after a State has failed to submit a SIP or a complete SIP, to make a finding to that effect and then to promulgate a FIP within 2 years of the finding. Although EPA would be exercising discretion to promulgate the FIP within the early part of the 2-year period, EPA would rescind the FIP for each State that submits a SIP that EPA approves, and, if the FIP remains, sources are not required to implement controls until after the close of the 2-year period. Moreover, as emphasized throughout the preamble, States are not required to adopt the FIP provisions, or any particular portion thereof, in order for EPA to approve their SIPs. Thus, Executive Order 13132 does not apply to this proposed rule.

   Even so, in the spirit of Executive Order 13132, and consistent with EPA policy to promote communications between EPA and State and local governments, EPA consulted with State and local officials early in the process of developing the proposed regulation to permit them to have meaningful and timely input into its development. The EPA is including a number of provisions for States in the proposed rule so as not to constrain States' abilities to complete approvable SIP revisions, such as the ability to submit abbreviated SIP revisions, and the intent to withdraw the FIP upon approval of State SIP revisions.

6. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments

   Executive Order 13175, entitled ``Consultation and Coordination with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), requires EPA to develop an accountable process to ensure ``meaningful and timely input by Tribal officials in the development of regulatory policies that have Tribal implications.'' This proposal does not have ``Tribal implications'' as specified in Executive Order 13175.

   This proposal addresses transport of pollution for precursors of ozone and PM2.5. The CAA provides for States and Tribes to develop plans to regulate emissions of air pollutants within their jurisdictions. The regulations clarify the statutory obligations of States and Tribes that develop plans to implement these rules. The Tribal Authority Rule (TAR) gives Tribes the opportunity to develop and implement CAA programs, but it leaves to the discretion of the Tribe whether to develop these programs and which programs, or appropriate elements of a program, the Tribe will adopt.

   This proposal does not have Tribal implications as defined by Executive Order 13175. It do not have a substantial direct effect on one or more Indian Tribes, because no Tribe has implemented a federally-enforceable air quality management program under the CAA at this time. Furthermore, this proposal does not affect the relationship or distribution of power and responsibilities between the Federal Government and Indian Tribes. The CAA and the TAR establish the relationship of the Federal Government

   [[Page 49745]]

   and Tribes in developing plans to attain the NAAQS, and this proposal does nothing to modify that relationship. Because this proposal does not have Tribal implications, Executive Order 13175 does not apply.

   If one assumes a Tribe is implementing a Tribal Implementation Plan, today's proposal could have implications for that Tribe, but would not impose substantial direct costs upon the Tribe, nor preempt Tribal law. As provided above, EPA has estimated that the total annual private costs for the FIP for the CAIR region as implemented by State, local, and Tribal governments to be approximately $2.4 billion in 2010 and $3.6 billion in 2015 (1999$). There are currently very few emissions sources in Indian country that could be affected by these rules and the percentage of Tribal land that will be impacted is very small. For Tribes that choose to regulate sources in Indian country, the costs would be attributed to inspecting regulated facilities and enforcing adopted regulations.

   EPA consulted with Tribal officials in developing the final CAIR rule. The EPA encouraged Tribal input at an early stage. Also, EPA held periodic meetings with the States and the Tribes during the technical development of CAIR. Three meetings were held with the Crow Tribe, where the Tribe expressed concerns about potential impacts of the rule on their coal mine operations. In addition, EPA held three calls with Tribal environmental professionals to address concerns specific to the Tribes. These discussions have given EPA valuable information about Tribal concerns regarding the development of CAIR. During the CAIR rulemaking process, the EPA provided briefings for Tribal representatives and the newly formed National Tribal Air Association (NTAA), and other national Tribal forums. Input from Tribal representatives was taken into consideration in development of CAIR.

7. Executive Order 13045: Protection of Children From Environmental Health and Safety Risks

   Executive Order 13045, ``Protection of Children from Environmental Health and Safety Risks'' (62 FR 19885, April 23, 1997) applies to any rule that (1) is determined to be ``economically significant'' as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, Section 5-501 of the Order directs the Agency to evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the Agency.

   These actions are not subject to the Executive Order, because they do not involve decisions on environmental health or safety risks that may disproportionately affect children. The EPA believes that the emissions reductions from the strategies in these proposals would further improve air quality and would further improve children's health.

8. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use

   Executive Order 13211 (66 FR 28355, May 22, 2001) provides that agencies shall prepare and submit to the Administrator of the Office of Regulatory Affairs, OMB, a Statement of Energy Effects for certain actions identified as ``significant energy actions.'' Section 4(b) of Executive Order 13211 defines ``significant energy actions'' as ``any action by an agency (normally published in the Federal Register) that promulgates or is expected to lead to the promulgation of a final rule or regulation, including notices of inquiry, advance notices of final rulemaking, and notices of final rulemaking (1) (i) a significant regulatory action under Executive Order 12866 or any successor order, and (ii) likely to have a significant adverse effect on the supply, distribution, or use of energy; or (2) designated by the Administrator of the Office of Information and Regulatory Affairs as a ``significant energy action.'' This proposed rule is a significant regulatory action under Executive Order 12866, and this rule may have a significant adverse effect on the supply, distribution, or use of energy. These impacts are detailed in the final CAIR (70 FR 25315).

   I. National Technology Transfer Advancement Act

   Section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-113; 15 U.S.C. 272 note) directs EPA to use voluntary consensus standards in its regulatory and procurement activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, business practices) developed or adopted by one or more voluntary consensus bodies. The NTTAA directs EPA to provide Congress, through annual reports to OMB, with explanations when an agency does not use available and applicable voluntary consensus standards.

   Today's proposed rule would implement requirements largely identical to the requirements in the CAIR. This proposal would require all sources that participate in the trading programs under part 97 (analogous to the CAIR SIP trading programs under part 96) to meet the applicable monitoring requirements of part 75. Part 75 already incorporates a number of voluntary consensus standards. Consistent with the Agency's Performance Based Measurement System (PBMS), part 75 sets forth performance criteria that allow the use of alternative methods to the ones set forth in part 75. The PBMS approach is intended to be more flexible and cost effective for the regulated community; it is also intended to encourage innovation in analytical technology and improved data quality. At this time, EPA is not recommending any revisions to part 75; however, EPA periodically revises the test procedures set forth in part 75. When EPA revises the test procedures set forth in part 75 in the future, EPA will address the use of any new voluntary consensus standards that are equivalent. Currently, even if a test procedure is not set forth in part 75, EPA is not precluding the use of any method, whether it constitutes a voluntary consensus standard or not, as long as it meets the performance criteria specified; however, any alternative methods must be approved through the petition process under Section 75.66 before they are used under part 75.

10. Executive Order 12898: Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations

    Executive Order 12898, ``Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations,'' requires Federal agencies to consider the impact of programs, policies, and activities on minority populations and low-income populations. According to EPA guidance,\22\ agencies are to assess whether minority or low-income populations face risks or a rate of exposure to hazards that are significant and that ``appreciably exceed or is likely to appreciably exceed the risk or rate to the general population or to the

    In accordance with Executive Order 12898, the Agency has considered whether these proposals, if promulgated, may have disproportionate negative impacts on minority or low-income populations. The Agency expects these proposals would lead to reductions in air pollution and exposures generally. For this reason, negative impacts to these sub- populations that appreciably exceed similar impacts to the general population are not expected.

      Sec. 97.141 Timing requirements for CAIR NOXallowance allocations.

      (

   1. The Administrator will determine by order the CAIR NOXallowance allocations, in accordance with Sec. 97.142(a) and (b), for the control periods in 2009, 2010, 2011, 2012, 2013, and 2014.

      (b) By July 31, 2011 and July 31 of each year thereafter, the Administrator will determine by order the CAIR NOXallowance allocations, in accordance with Sec. 97.142(a) and (b), for the control period in the fourth year after the year of the applicable deadline for the determination under this paragraph.

      (c) By July 31, 2009 and July 31 of each year thereafter, the Administrator will determine by order the CAIR NOXallowance allocations, in accordance

      [[Page 49774]]

      with Sec. 97.142(a),(c), and (d), for the control period in the year of the applicable deadline for the determination under this paragraph.

      (d) The Administrator will make available to the public each determination of CAIR NOXallowances under paragraph (a), (b), or (c) of this section and will provide an opportunity for submission of objections to the determination. Objections shall be limited to addressing whether the determination is in accordance with Sec. 97.142. Based on any such objections, the Administrator will adjust each determination to the extent necessary to ensure that it is in accordance with Sec. 97.142.

      Sec. 97.142 CAIR NOX allowance allocations.

      (a)(1) The baseline heat input (in mmBtu) used with respect to CAIR NOXallowance allocations under paragraph (b) of this section for each CAIR NOXunit will be:

      (i) For units commencing operation before January 1, 2001 the average of the 3 highest amounts of the unit's adjusted control period heat input for 2000 through 2004, with the adjusted control period heat input for each year calculated as follows:

      (

1. If the unit is coal-fired during the year, the unit's control period heat input for such year is multiplied by 100 percent;

   (B) If the unit is oil-fired during the year, the unit's control period heat input for such year is multiplied by 60 percent; and

   (C) If the unit is not subject to paragraph (a)(1)(i)(A) or (B) of this section, the unit's control period heat input for such year is multiplied by 40 percent.

   (ii) For units commencing operation on or after January 1, 2001 and operating each calendar year during a period of 5 or more consecutive calendar years, the average of the 3 highest amounts of the unit's total converted control period heat input over the first such 5 years.

   (2)(i) A unit's control period heat input, and a unit's status as coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) of this section, and a unit's total tons of NOXemissions during a calendar year under paragraph (c)(3) of this section, will be determined in accordance with part 75 of this chapter, to the extent the unit was otherwise subject to the requirements of part 75 of this chapter for the year, or will be determined based on the best available data reported to the Administrator for the unit, to the extent the unit was not otherwise subject to the requirements of part 75 of this chapter for the year.

   (ii) A unit's converted control period heat input for a calendar year specified under paragraph (a)(1)(ii) of this section equals:

   (

1. Except as provided in paragraph (a)(2)(ii)(B) or (C) of this section, the control period gross electrical output of the generator or generators served by the unit multiplied by 7,900 Btu/kWh, if the unit is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal- fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that if a generator is served by 2 or more units, then the gross electrical output of the generator will be attributed to each unit in proportion to the unit's share of the total control period heat input of such units for the year;

   (B) For a unit that is a boiler and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the total heat energy (in Btu) of the steam produced by the boiler during the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or

   (C) For a unit that is a combustion turbine and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the control period gross electrical output of the enclosed device comprising the compressor, combustor, and turbine multiplied by 3,413 Btu/kWh, plus the total heat energy (in Btu) of the steam produced by any associated heat recovery steam generator during the control period divided by 0.8, and with the sum divided by 1,000,000 Btu/mmBtu.

   (iii) Gross electrical output and total heat energy under paragraph (a)(2)(ii) of this section will be determined based on the best available data reported to the Administrator.

   (3) The Administrator will determine what data are the best available data under paragraph (a)(2) of this section by weighing the likelihood that data are accurate and reliable and will give greater weight to data submitted to a governmental entity in compliance with legal requirements or substantiated by an independent entity.

   (b)(1) For each control period in 2009 and thereafter, the Administrator will allocate to all CAIR NOXunits in a State that have a baseline heat input (as determined under paragraph (a) of this section) a total amount of CAIR NOXallowances equal to 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the tons of NOXemissions in the State trading budget for such State under Sec. 97.140 (except as provided in paragraphs (d) and (e) of this section).

   (2) The Administrator will allocate CAIR NOXallowances to each CAIR NOXunit under paragraph (b)(1) of this section in an amount determined by multiplying the total amount of CAIR NOXallowances allocated under paragraph (b)(1) of this section by the ratio of the baseline heat input of such CAIR NOXunit to the total amount of baseline heat input of all such CAIR NOXunits in the State and rounding to the nearest whole allowance as appropriate.

   (c) For each control period in 2009 and thereafter, the Administrator will allocate CAIR NOXallowances to CAIR NOXunits in a State that commenced operation on or after January 1, 2001 and do not yet have a baseline heat input (as determined under paragraph (a) of this section), in accordance with the following procedures:

   (1) The Administrator will establish a separate new unit set-aside for each control period. Each new unit set-aside will be allocated CAIR NOXallowances equal to 5 percent for a control period in 2009 through 2014, and 3 percent for a control period in 2015 and thereafter, of the amount of tons of NOXemissions in the State trading budget for the State under Sec. 97.140.

   (2) The CAIR designated representative of such a CAIR NOXunit may submit to the Administrator a request, in a format specified by the Administrator, to be allocated CAIR NOXallowances, starting with the later of the control period in 2009 or the first control period after the control period in which the CAIR NOXunit commences commercial operation and until the first control period for which the unit is allocated CAIR NOXallowances under paragraph (b) of this section. The CAIR NOXallowance allocation request must be submitted on or before May 1 of the first control period for which the CAIR NOXallowances are requested and after the date on which the CAIR NOXunit commences commercial operation.

   (3) In a CAIR NOXallowance allocation request under paragraph (c)(2) of this section, the CAIR designated representative may request for a control period CAIR NOXallowances in an amount not exceeding the CAIR NOXunit's total tons of NOXemissions during the calendar year immediately before such control period.

   (4) The Administrator will review each CAIR NOX allowance allocation request under paragraph (c)(2) of this section and will allocate CAIR NOX

   [[Page 49775]]

   allowances for each control period pursuant to such request as follows:

   (i) The Administrator will accept an allowance allocation request only if the request meets, or is adjusted by the Administrator as necessary to meet, the requirements of paragraphs (c)(2) and (3) of this section.

   (ii) On or after May 1 of the control period, the Administrator will determine the sum of the CAIR NOXallowances requested (as adjusted under paragraph (c)(4)(i) of this section) in all allowance allocation requests accepted under paragraph (c)(4)(i) of this section for the control period.

   (iii) If the amount of CAIR NOXallowances in the new unit set-aside for the control period is greater than or equal to the sum under paragraph (c)(4)(ii) of this section, then the Administrator will allocate the amount of CAIR NOXallowances requested (as adjusted under paragraph (c)(4)(i) of this section) to each CAIR NOXunit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section.

   (iv) If the amount of CAIR NOXallowances in the new unit set-aside for the control period is less than the sum under paragraph (c)(4)(ii) of this section, then the Administrator will allocate to each CAIR NOXunit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section the amount of the CAIR NOXallowances requested (as adjusted under paragraph (c)(4)(i) of this section), multiplied by the amount of CAIR NOXallowances in the new unit set-aside for the control period, divided by the sum determined under paragraph (c)(4)(ii) of this section, and rounded to the nearest whole allowance as appropriate.

   (v) The Administrator will notify each CAIR designated representative that submitted an allowance allocation request of the amount of CAIR NOXallowances (if any) allocated for the control period to the CAIR NOXunit covered by the request.

   (d) If, after completion of the procedures under paragraph (c)(4) of this section for a control period, any unallocated CAIR NOXallowances remain in the new unit set-aside under paragraph (c) of this section for a State for the control period, the Administrator will allocate to each CAIR NOXunit that was allocated CAIR NOXallowances under paragraph (b) of this section an amount of CAIR NOXallowances equal to the total amount of such remaining unallocated CAIR NOXallowances, multiplied by the unit's allocation under paragraph (b) of this section, divided by 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the amount of tons of NOXemissions in the State trading budget for such State under Sec. 97.140, and rounded to the nearest whole allowance as appropriate.

   (e) If the Administrator determines that CAIR NOX allowances were allocated under paragraphs (a) and (b) of this section, paragraphs (a) and (c) of this section, or paragraph (d) of this section for a control period and that the recipient of the allocation is not actually a CAIR NOXunit under Sec. 97.104 in such control period, then the Administrator will notify the CAIR designated representative and will act in accordance with the following procedures:

   (1) Except as provided in paragraph (e)(2) or (3) of this section, the Administrator will not record such CAIR NOXallowances under Sec. 97.153.

   (2) If the Administrator already recorded such CAIR NOX allowances under Sec. 97.153 and if the Administrator makes such determination before making deductions for the source that includes such recipient under Sec. 97.154(b) for the control period, then the Administrator will deduct from the account in which such CAIR NOXallowances were recorded under Sec. 97.153 an amount of CAIR NOXallowances allocated for the same or a prior control period equal to the amount of such already recorded CAIR NOXallowances. The CAIR authorized account representative shall ensure that there are sufficient CAIR NOXallowances in such account for completion of the deduction.

   (3) If the Administrator already recorded such CAIR NOX allowances under Sec. 97.153 and if the Administrator makes such determination after making deductions for the source that includes such recipient under Sec. 97.154(b) for the control period, then the Administrator will apply paragraph (e)(1) or (2) of this section, as appropriate, to any subsequent control period for which CAIR NOXallowances were allocated to such recipient.

   (4) The Administrator will transfer the CAIR NOX allowances that are not recorded, or that are deducted, in accordance with paragraphs (e)(1), (2), and (3) of this section to a new unit set- aside for the State in which such recipient is located.

   Sec. 97.143 Compliance supplement pool.

      (b) For any CAIR NOXunit in a State whose average annual NOXemission rate for 2007 or 2008 is less than 0.25 lb/mmBtu and, if such unit is included in a NOXaveraging plan under Sec. 76.11 of this chapter under the Acid Rain Program for such year, whose NOXaveraging plan has an actual weighted average NOXemission rate for such year equal to or less than the actual weighted average NOXemission rate for the year before such year achieves NOXemission reductions in 2007 and 2008, the CAIR designated representative of the unit may request early reduction credits, and allocation of CAIR NOX allowances from the compliance supplement pool under paragraph (a) of this section for such early reduction credits, in accordance with the following:

      (1) The owners and operators of such CAIR NOXunit shall monitor and report the NOXemissions rate and the heat input of the unit in accordance with subpart HH of this part in each control period for which early reduction credit is requested.

      (2) The CAIR designated representative of such CAIR NOX unit shall submit to the Administrator by July 1, 2009 a request, in a format specified by the Administrator, for allocation of an amount of CAIR NOXallowances from the compliance supplement pool not exceeding the sum of the unit's heat input for the control

      [[Page 49776]]

      period in 2007 multiplied by the difference (if any greater than zero) between 0.25 lb/mmBtu and the unit's NOXemission rate for the control period in 2007 plus the unit's heat input for the control period in 2008 multiplied by the difference (if any greater than zero) between 0.25 lb/mmBtu and the unit's NOXemission rate for the control period in 2008, determined in accordance with subpart HH of this part and with the sum divided by 2,000 lb/ton and rounded to the nearest whole number of tons as appropriate.

      (c) For any CAIR NOXunit in a State whose compliance with CAIR NOXemissions limitation for the control period in 2009 would create an undue risk to the reliability of electricity supply during such control period, the CAIR designated representative of the unit may request the allocation of CAIR NOX allowances from the compliance supplement pool under paragraph (a) of this section, in accordance with the following:

      (1) The CAIR designated representative of such CAIR NOX unit shall submit to the Administrator by July 1, 2009 a request, in a format specified by the Administrator, for allocation of an amount of CAIR NOXallowances from the compliance supplement pool not exceeding the minimum amount of CAIR NOXallowances necessary to remove such undue risk to the reliability of electricity supply.

      (2) In the request under paragraph (c)(1) of this section, the CAIR designated representative of such CAIR NOXunit shall demonstrate that, in the absence of allocation to the unit of the amount of CAIR NOXallowances requested, the unit's compliance with CAIR NOXemissions limitation for the control period in 2009 would create an undue risk to the reliability of electricity supply during such control period. This demonstration must include a showing that it would not be feasible for the owners and operators of the unit to:

      (i) Obtain a sufficient amount of electricity from other electricity generation facilities, during the installation of control technology at the unit for compliance with the CAIR NOX emissions limitation, to prevent such undue risk; or

      (ii) Obtain under paragraphs (b) and (d) of this section, or otherwise obtain, a sufficient amount of CAIR NOXallowances to prevent such undue risk.

      (d) The Administrator will review each request under paragraph (b) or (c) of this section submitted by July 1, 2009 and will allocate CAIR NOXallowances for the control period in 2009 to CAIR NOXunits in a State and covered by such request as follows:

      (1) Upon receipt of each such request, the Administrator will make any necessary adjustments to the request to ensure that the amount of the CAIR NOXallowances requested meets the requirements of paragraph (b) or (c) of this section.

      (2) If the State's compliance supplement pool under paragraph (a) of this section has an amount of CAIR NOXallowances not less than the total amount of CAIR NOXallowances in all such requests (as adjusted under paragraph (d)(1) of this section), the Administrator will allocate to each CAIR NOXunit covered by such requests the amount of CAIR NOXallowances requested (as adjusted under paragraph (d)(1) of this section).

      (3) If the State's compliance supplement pool under paragraph (a) of this section has a smaller amount of CAIR NOXallowances than the total amount of CAIR NOXallowances in all such requests (as adjusted under paragraph (d)(1) of this section), the Administrator will allocate CAIR NOXallowances to each CAIR NOXunit covered by such requests according to the following formula and rounding to the nearest whole allowance as appropriate:

      Unit's allocation = Unit's adjusted allocation x (State's compliance supplement pool / Total adjusted allocations for all units)

      Where:

      ``Unit's allocation'' is the amount of CAIR NOX allowances allocated to the unit from the State's compliance supplement pool.

      Sec. 97.186 Withdrawal from CAIR NOX Annual Trading Program.

      Except as provided under paragraph (g) of this section, a CAIR NOXopt-in unit may withdraw from the CAIR NOX Annual Trading Program, but only if the permitting authority issues a notification to the CAIR designated representative of the CAIR NOXopt-in unit of the acceptance of the withdrawal of the CAIR NOXopt-in unit in accordance with paragraph (d) of this section.

      (

   1. Requesting withdrawal. In order to withdraw a CAIR NOXopt-in unit from the CAIR NOXAnnual Trading Program, the CAIR designated representative of the CAIR NOX opt-in unit shall submit to the permitting authority a request to withdraw effective as of midnight of December 31 of a specified calendar year, which date must be at least 4 years after December 31 of the year of entry into the CAIR NOXAnnual Trading Program under Sec. 97.184(g). The request must be submitted no later than 90 days before the requested effective date of withdrawal.

      (b) Conditions for withdrawal. Before a CAIR NOXopt-in unit covered by a request under paragraph (a) of this section may withdraw from the CAIR NOXAnnual Trading Program and the CAIR opt-in permit may be terminated under paragraph (e) of this section, the following conditions must be met:

      (1) For the control period ending on the date on which the withdrawal is to be effective, the source that includes the CAIR NOXopt-in unit must meet the requirement to hold CAIR NOXallowances under Sec. 97.106(c) and cannot have any excess emissions.

      (2) After the requirement for withdrawal under paragraph (b)(1) of this section is met, the Administrator will deduct from the compliance account of the source that includes the CAIR NOXopt-in unit CAIR NOXallowances equal in amount to and allocated for the same or a prior control period as any CAIR NOXallowances allocated to the CAIR NOXopt-in unit under Sec. 97.188 for any control period for which the withdrawal is to be effective. If there are no remaining CAIR NOXunits at the source, the Administrator will close the compliance account, and the owners and operators of the CAIR NOXopt-in unit may submit a CAIR NOXallowance transfer for any remaining CAIR NOX allowances to another CAIR NOXAllowance Tracking System in accordance with subpart GG of this part.

      (c) Notification. (1) After the requirements for withdrawal under paragraphs (a) and (b) of this section are met (including deduction of the full amount of CAIR NOXallowances required), the permitting authority will issue a notification to the CAIR designated representative of the CAIR NOXopt-in unit of the acceptance of the withdrawal of the CAIR NOXopt-in unit as of midnight on December 31 of the calendar year for which the withdrawal was requested.

      (2) If the requirements for withdrawal under paragraphs (a) and (b) of this section are not met, the permitting authority will issue a notification to the CAIR designated representative of the CAIR NOXopt-in unit that the CAIR NOXopt-in unit's request to withdraw is denied. Such CAIR NOXopt-in unit shall continue to be a CAIR NOXopt-in unit.

      (d) Permit amendment. After the permitting authority issues a notification under paragraph (c)(1) of this section that the requirements for withdrawal have been met, the permitting authority will revise the CAIR permit covering the CAIR NOXopt-in unit to terminate the CAIR opt-in permit for such unit as of the effective date specified under paragraph (c)(1) of this section. The unit shall continue to be a CAIR NOXopt-in unit until the effective date of the termination and shall comply with all requirements under the CAIR NOXAnnual Trading Program concerning any control periods for which the unit is a CAIR NOXopt-in unit, even if such requirements arise or must be complied with after the withdrawal takes effect.

      (e) Reapplication upon failure to meet conditions of withdrawal. If the permitting authority denies the CAIR NOXopt-in unit's request to withdraw,

      [[Page 49786]]

      the CAIR designated representative may submit another request to withdraw in accordance with paragraphs (a) and (b) of this section.

      (f) Ability to reapply to the CAIR NOXAnnual Trading Program. Once a CAIR NOXopt-in unit withdraws from the CAIR NOXAnnual Trading Program and its CAIR opt-in permit is terminated under this section, the CAIR designated representative may not submit another application for a CAIR opt-in permit under Sec. 97.183 for such CAIR NOXopt-in unit before the date that is 4 years after the date on which the withdrawal became effective. Such new application for a CAIR opt-in permit will be treated as an initial application for a CAIR opt-in permit under Sec. 97.184.

      (g) Inability to withdraw. Notwithstanding paragraphs (a) through (f) of this section, a CAIR NOXopt-in unit shall not be eligible to withdraw from the CAIR NOXAnnual Trading Program if the CAIR designated representative of the CAIR NOXopt-in unit requests, and the permitting authority issues a CAIR NOXopt-in permit providing for, allocation to the CAIR NOXopt-in unit of CAIR NOXallowances under Sec. 97.188(c).

   Sec. 97.254 Compliance with CAIR SO2 emissions limitation.

   (

   1. Allowance transfer deadline. The CAIR SO2allowances are available to be deducted for compliance with a source's CAIR SO2emissions limitation for a control period in a given calendar year only if the CAIR SO2allowances:

   (1) Were allocated for the control period in the year or a prior year;

   (2) Are held in the compliance account as of the allowance transfer deadline for the control period or are transferred into the compliance account by a CAIR SO2allowance transfer correctly submitted for recordation under Sec. 97.260 by the allowance transfer deadline for the control period; and

   (3) Are not necessary for deductions for excess emissions for a prior control period under paragraph (d) of this section or for deduction under part 77 of this chapter.

   (b) Deductions for compliance. Following the recordation, in accordance with Sec. 97.261, of CAIR SO2allowance transfers submitted for recordation in a source's compliance account by the allowance transfer deadline for a control period, the Administrator will deduct from the compliance account CAIR SO2allowances available under paragraph (a) of this section in order to determine whether the source meets the CAIR SO2emissions limitation for the control period as follows:

   (1) For a CAIR SO2source subject to an Acid Rain emissions limitation, the Administrator will, in the following order:

   (i) Deduct the amount of CAIR SO2allowances, available under paragraph (a) of this section and not issued by a permitting authority under Sec. 97.288, that is required under Sec. Sec. 73.35(b) and (c) of this part. If there are sufficient CAIR SO2allowances to complete this deduction, the deduction will be treated as satisfying the requirements of Sec. Sec. 73.35(b) and (c) of this chapter.

   (ii) Deduct the amount of CAIR SO2allowances, available under paragraph (a) of this section and not issued by a permitting authority under Sec. 97.288, that is required under Sec. Sec. 73.35(d) and 77.5 of this part. If there are sufficient CAIR SO2allowances to complete this deduction, the deduction will be treated as satisfying the requirements of Sec. Sec. 73.35(d) and 77.5 of this chapter.

   (iii) Treating the CAIR SO2allowances deducted under paragraph (b)(1)(i) of this section as also being deducted under this paragraph (b)(1)(iii), deduct CAIR SO2allowances available under paragraph (a) of this section (including any issued by a permitting authority under Sec. 97.288) in order to determine whether the source meets the CAIR SO2emissions limitation for the control period, as follows:

   (

1. Until the tonnage equivalent of the CAIR SO2 allowances deducted equals, or exceeds in accordance with paragraphs (c)(1) and (2) of this section, the number of tons of total sulfur dioxide emissions, determined in accordance with subpart HHH of this part, from all CAIR SO2units at the source for the control period; or

   (B) If there are insufficient CAIR SO2allowances to complete the deductions in paragraph (b)(1)(iii)(A) of this section, until no more CAIR SO2allowances available under paragraph (a) of this section (including any issued by a permitting authority under Sec. 97.288) remain in the compliance account.

   (2) For a CAIR SO2source not subject to an Acid Rain emissions limitation, the Administrator will deduct CAIR SO2 allowances available under paragraph (a) of this section (including any issued by a permitting authority under Sec. 97.288) in order to determine whether the source meets the CAIR SO2emissions limitation for the control period, as follows:

   (i) Until the tonnage equivalent of the CAIR SO2 allowances deducted equals, or exceeds in accordance with paragraphs (c)(1) and (2) of this section, the number of tons of total sulfur dioxide emissions, determined in accordance with subpart HHH of this part, from all CAIR SO2units at the source for the control period; or

   (ii) If there are insufficient CAIR SO2allowances to complete the deductions in paragraph (b)(2)(i) of this section, until no more CAIR SO2allowances available under paragraph (a) of this section (including any issued by a permitting authority Sec. 97.288) remain in the compliance account.

   (c)(1) Identification of CAIR SO2allowances by serial number. The CAIR authorized account representative for a source's compliance account may request that specific CAIR SO2 allowances, identified by serial number, in the compliance account be deducted for emissions or excess emissions for a control period in accordance with paragraph (b) or (d) of this section. Such request shall be submitted to the Administrator by the allowance transfer deadline for the control period and include, in a format prescribed by the Administrator, the identification of the CAIR SO2source and the appropriate serial numbers.

   (2) First-in, first-out. The Administrator will deduct CAIR SO2allowances under paragraph (b) or (d) of this section from the source's compliance account, in the absence of an identification or in the case of a partial identification of CAIR SO2allowances by serial number under paragraph (c)(1) of this section, on a first-in, first-out (FIFO) accounting basis in the following order:

   (i) Any CAIR SO2allowances that were allocated to the units at the source for a control period before 2010, in the order of recordation;

   [[Page 49800]]

   (ii) Any CAIR SO2allowances that were allocated to any entity for a control period before 2010 and transferred and recorded in the compliance account pursuant to subpart GGG of this part or subpart D of part 73 of this chapter, in the order of recordation;

   (iii) Any CAIR SO2allowances that were allocated to the units at the source for a control period during 2010 through 2014, in the order of recordation;

   (vi) Any CAIR SO2allowances that were allocated to any entity for a control period in 2015 or later and transferred and recorded in the compliance account pursuant to subpart GGG of this part or subpart D of part 73 of this chapter, in the order of recordation.

   (d) Deductions for excess emissions. (1) After making the deductions for compliance under paragraph (b) of this section for a control period in a calendar year in which the CAIR SO2 source has excess emissions, the Administrator will deduct from the source's compliance account the tonnage equivalent in CAIR SO2allowances, allocated for the control period in the immediately following calendar year (including any issued by a permitting authority under Sec. 97.288), equal to, or exceeding in accordance with paragraphs (c)(1) and (2) of this section the sum of the following amounts:

   (i) The number of tons of the source's excess emissions minus, if the source is subject to an Acid Rain emissions limitation, the amount of the CAIR SO2allowances required to be deducted under paragraph (b)(1)(ii) of this section; and

   (ii) Two times: (

1. The number of tons of the source's excess emissions, if the source is not subject to an Acid Rain emissions limitation; or

   (B) The number of tons of the source's excess emissions minus the amount of the CAIR SO2allowances required to be deducted under paragraph (b)(1)(ii) of this section, if the source is subject to an Acid Rain emissions limitation.

   (2) Any allowance deduction required under paragraph (d)(1) of this section shall not affect the liability of the owners and operators of the CAIR SO2source or the CAIR SO2units at the source for any fine, penalty, or assessment, or their obligation to comply with any other remedy, for the same violations, as ordered under the Clean Air Act or applicable State law.

   (e) Recordation of deductions. The Administrator will record in the appropriate compliance account all deductions from such an account under paragraph (b) or (d) of this section.

   (f) Administrator's action on submissions. (1) The Administrator may review and conduct independent audits concerning any submission under the CAIR SO2Trading Program and make appropriate adjustments of the information in the submissions.

   (2) The Administrator may deduct CAIR SO2allowances from or transfer CAIR SO2allowances to a source's compliance account based on the information in the submissions, as adjusted under paragraph (f)(1) of this section.

   Sec. 97.255 Banking.

   (

   1. CAIR SO2allowances may be banked for future use or transfer in a compliance account or a general account in accordance with paragraph (b) of this section.

      (b) Any CAIR SO2allowance that is held in a compliance account or a general account will remain in such account unless and until the CAIR SO2allowance is deducted or transferred under Sec. 97.254, Sec. 97.256, or subpart GGG of this part.

      Sec. 97.256 Account error.

      The Administrator may, at his or her sole discretion and on his or her own motion, correct any error in any CAIR SO2Allowance Tracking System account. Within 10 business days of making such correction, the Administrator will notify the CAIR authorized account representative for the account.

   1. Interim review of monitoring plan. The permitting authority and the Administrator will determine, on an interim basis, the sufficiency of the monitoring plan accompanying the initial application for a CAIR opt-in permit under Sec. 97.283. A monitoring plan is sufficient, for purposes of interim review, if the plan appears to contain information demonstrating that the NOXemissions rate and heat input of the unit and all other applicable parameters are monitored and reported in accordance with subpart HH of this part. A determination of sufficiency shall not be construed as acceptance or approval of the monitoring plan.

      (b) Monitoring and reporting. (1)(i) If the permitting authority and the Administrator determines that the monitoring plan is sufficient under paragraph (a) of this section, the owner or operator shall monitor and report the SO2emissions rate and the heat input of the unit and all other applicable parameters, in accordance with subpart HHH of this part, starting on the date of certification of the appropriate monitoring systems under subpart HH of this part and continuing until a CAIR opt-in permit is denied under Sec. 97.284(f) or, if a CAIR opt-in permit is issued, the date and time when the unit is withdrawn from the CAIR SO2Trading Program in accordance with Sec. 97.286.

      (ii) The monitoring and reporting under paragraph (b)(1)(i) of this section shall include the entire control period immediately before the date on which the unit enters the CAIR SO2Trading Program under Sec. 97.284(g), during which period monitoring system availability must not be less than 90 percent under subpart HHH of this part and the unit must be in full compliance with any applicable State or Federal emissions or emissions-related requirements.

      (2) To the extent the SO2emissions rate and the heat input of the unit are monitored and reported in accordance with subpart HHH of this part for one or more control periods, in addition to the control period under paragraph (b)(1)(ii) of this section, during which control periods monitoring system availability is not less than 90 percent under subpart HHH of this part and the unit is in full compliance with any applicable State or Federal emissions or emissions- related requirements and which control periods begin not more than 3 years before the unit enters the CAIR SO2Trading Program under Sec. 97.284(g), such information shall be used as provided in paragraphs (c) and (d) of this section.

      (c) Baseline heat input. The unit's baseline heat rate shall equal:

      (1) If the unit's SO2emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's total heat input (in mmBtu) for the control period; or

      (2) If the unit's SO2emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, the average of the amounts of the unit's total heat input (in mmBtu) for the control periods under paragraphs (b)(1)(ii) and (b)(2) of this section.

      (d) Baseline SO2emission rate. The unit's baseline SO2emission rate shall equal:

      (1) If the unit's SO2emissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's NOXemissions rate (in lb/mmBtu) for the control period;

      (2) If the unit's SO2emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit does not have add-on SO2emission controls during any such control periods, the average of the amounts of the unit's SO2 emissions rate (in lb/mmBtu) for the control periods under paragraphs (b)(1)(ii) and (b)(2) of this section; or

      (3) If the unit's SO2emissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit has add-on SO2emission controls during any

      [[Page 49806]]

      such control periods, the average of the amounts of the unit's SO2emissions rate (in lb/mmBtu) for such control periods during which the unit has add-on SO2emission controls.

      (e) Issuance of CAIR opt-in permit. After calculating the baseline heat input and the baseline SO2emissions rate for the unit under paragraphs (c) and (d) of this section and if the permitting authority determines that the CAIR designated representative shows that the unit meets the requirements for a CAIR SO2opt-in unit in Sec. 97.280 and meets the elements certified in Sec. 97.283(a)(2), the permitting authority will issue a CAIR opt-in permit. The permitting authority will provide a copy of the CAIR opt-in permit to the Administrator, who will then establish a compliance account for the source that includes the CAIR SO2opt-in unit unless the source already has a compliance account.

      (f) Issuance of denial of CAIR opt-in permit. Notwithstanding paragraphs (a) through (e) of this section, if at any time before issuance of a CAIR opt-in permit for the unit, the permitting authority determines that the CAIR designated representative fails to show that the unit meets the requirements for a CAIR SO2opt-in unit in Sec. 97.280 or meets the elements certified in Sec. 97.283(a)(2), the permitting authority will issue a denial of a CAIR opt-in permit for the unit.

      (g) Date of entry into CAIR SO2 Annual Trading Program. A unit for which an initial CAIR opt-in permit is issued by the permitting authority shall become a CAIR SO2opt-in unit, and a CAIR SO2unit, as of the later of January 1, 2009 or January 1 of the first control period during which such CAIR opt-in permit is issued.

      (h) Repowered CAIR SO2 opt-in unit. (1) If CAIR designated representative requests, and the permitting authority issues a CAIR opt-in permit providing for, allocation to a CAIR SO2opt-in unit of CAIR SO2allowances under Sec. 97.288(c) and such unit is repowered after its date of entry into the CAIR SO2 Trading Program under paragraph (g) of this section, the repowered unit shall be treated as a CAIR SO2opt-in unit replacing the original CAIR SO2opt-in unit, as of the date of start-up of the repowered unit's combustion chamber.

      (2) Notwithstanding paragraphs (c) and (d) of this section, as of the date of start-up under paragraph (h)(1) of this section, the repowered unit shall be deemed to have the same date of commencement of operation, date of commencement of commercial operation, baseline heat input, and baseline NOXemission rate as the original CAIR SO2opt-in unit, and the original CAIR SO2opt-in unit shall no longer be treated as a CAIR SO2opt-in unit or a CAIR SO2unit.

      Sec. 97.341 Timing requirements for CAIR NOX Ozone Season allowance allocations.

      (

   1. The Administrator will determine by order the CAIR NOXOzone Season allowance allocations, in accordance with Sec. 97.342(a) and (b), for the control periods in 2009, 2010, 2011, 2012, 2013, and 2014.

      (b) By July 31, 2011 and July 31 of each year thereafter, the Administrator will determine by order the CAIR NOXOzone Season allowance allocations, in accordance with Sec. 97.342(a) and (b), for the control period in the fourth year after the year of the applicable deadline for determination under this paragraph.

      (c) By April 30, 2009 and April 30 of each year thereafter, the Administrator will determine by order the CAIR NOXOzone Season allowance allocations, in accordance with Sec. 97.342(a), (c), and (d), for the control period in the year of the applicable deadline for submission under this paragraph.

      (d) The Administrator will make available to the public each determination of CAIR NOXOzone Season allowances under paragraph (a), (b), or (c) of this section and will provide an opportunity for submission of objections to the determination. Objections shall be limited to addressing whether the determination is in accordance with Sec. 97.342. Based on any such objections, the Administrator will adjust each determination to the extent necessary to ensure that it is in accordance with Sec. 97.342.

      Sec. 97.342 CAIR NOX Ozone Season allowance allocations.

      (a)(1) The baseline heat input (in mmBtu) used with respect to CAIR NOXOzone Season allowance allocations under paragraph (b) of this section for each CAIR NOXOzone Season unit will be:

      (i) For units commencing operation before January 1, 2001 the average of the 3 highest amounts of the unit's adjusted control period heat input for 2000 through 2004, with the adjusted control period heat input for each year calculated as follows:

      (

1. If the unit is coal-fired during the year, the unit's control period heat input for such year is multiplied by 100 percent;

   (B) If the unit is oil-fired during the year, the unit's control period heat input for such year is multiplied by 60 percent; and

   (C) If the unit is not subject to paragraph (a)(1)(i)(A) or (B) of this section, the unit's control period heat input for such year is multiplied by 40 percent.

   (ii) For units commencing operation on or after January 1, 2001 and operating each calendar year during a period of 5 or more consecutive calendar years, the average of the 3 highest amounts of the unit's total converted control period heat input over the first such 5 years.

   (2)(i) A unit's control period heat input, and a unit's status as coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) of this section, and a unit's total tons of NOXemissions during a control period in a calendar year under paragraph (c)(3) of this section, will be determined in accordance with part 75 of this chapter, to the extent the unit was otherwise subject to the requirements of part 75 of this chapter for the year, or will be determined based on the best available data reported to the Administrator for the unit, to the extent the unit was not otherwise subject to the requirements of part 75 of this chapter for the year.

   (ii) A unit's converted control period heat input for a calendar year specified under paragraph (a)(1)(ii) of this section equals:

   (

1. Except as provided in paragraph (a)(2)(ii)(B) or (C) of this section, the control period gross electrical output of the generator or generators served by the unit multiplied by 7,900 Btu/kWh, if the unit is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal- fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that if a generator is served by 2 or more units, then the gross electrical output of the generator will be attributed to each unit in proportion to the unit's share of the total control period heat input of such units for the year;

   (B) For a unit that is a boiler and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the total heat energy (in Btu) of the steam produced by the boiler during the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or

   (C) For a unit that is a combustion turbine and has equipment used to produce electricity and useful thermal energy for industrial, commercial, heating, or cooling purposes through the sequential use of energy, the control period gross electrical output of the enclosed device comprising the compressor, combustor, and turbine multiplied by 3,413 Btu/kWh, plus the total heat energy (in Btu) of the steam produced by any associated heat recovery steam generator during the control period divided by 0.8, and with the sum divided by 1,000,000 Btu/mmBtu.

   (iii) Gross electrical output and total heat energy under paragraph (a)(2)(ii) of this section will be determined based on the best available data reported to the Administrator.

   (3) The Administrator will determine what data are the best available data under paragraph (a)(2) of this section by weighing the likelihood that data are accurate and reliable and will give greater weight to data submitted to a governmental entity in compliance with legal requirements or substantiated by an independent entity.

   (b)(1) For each control period in 2009 and thereafter, the Administrator will allocate to all CAIR NOXOzone Season units in a State that have a baseline heat input (as determined under paragraph (a) of this section) a total amount of CAIR NOX Ozone Season allowances equal to 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the tons of NOXemissions in the State trading budget for such State under Sec. 97.340 (except as provided in paragraphs (d) and (e) of this section).

   (2) The Administrator will allocate CAIR NOXOzone Season allowances to each CAIR NOXOzone Season unit under paragraph (b)(1) of this section in an amount determined by multiplying the total amount of CAIR NOXOzone Season allowances allocated under paragraph (b)(1) of this section by the ratio of the baseline heat input of such CAIR NOXOzone Season unit to the total amount of baseline heat input of all such CAIR NOX Ozone Season units in the State and rounding to the nearest whole allowance as appropriate.

   (c) For each control period in 2009 and thereafter, the Administrator will allocate CAIR NOXOzone Season allowances to CAIR NOXOzone Season units in a State that commenced operation on or after January 1, 2001 and do not yet have a baseline heat input (as determined under paragraph (a) of this section), in accordance with the following procedures:

   [[Page 49821]]

   (1) The Administrator will establish a separate new unit set-aside for each control period. Each new unit set-aside will be allocated CAIR NOXOzone Season allowances equal to 5 percent for a control period in 2009 through 2014, and 3 percent for a control period in 2015 and thereafter, of the amount of tons of NOXemissions in the State trading budget for the State under Sec. 97.340.

   (2) The CAIR designated representative of such a CAIR NOXOzone Season unit may submit to the Administrator a request, in a format specified by the the Administrator, to be allocated CAIR NOXOzone Season allowances, starting with the later of the control period in 2009 or the first control period after the control period in which the CAIR NOXOzone Season unit commences commercial operation and until the first control period for which the unit is allocated CAIR NOXOzone Season allowances under paragraph (b) of this section. The CAIR NOX Ozone Season allowance allocation request must be submitted on or before February 1 before the first control period for which the CAIR NOXOzone Season allowances are requested and after the date on which the CAIR NOXOzone Season unit commences commercial operation.

   (3) In a CAIR NOXOzone Season allowance allocation request under paragraph (c)(2) of this section, the CAIR designated representative may request for a control period CAIR NOX Ozone Season allowances in an amount not exceeding the CAIR NOXOzone Season unit's total tons of NOX emissions during the control period immediately before such control period.

   (4) The Administrator will review each CAIR NOXOzone Season allowance allocation request under paragraph (c)(2) of this section and will allocate CAIR NOXOzone Season allowances for each control period pursuant to such request as follows:

   (i) The Administrator will accept an allowance allocation request only if the request meets, or is adjusted by the Administrator as necessary to meet, the requirements of paragraphs (c)(2) and (3) of this section.

   (ii) On or after February 1 before the control period, the Administrator will determine the sum of the CAIR NOXOzone Season allowances requested (as adjusted under paragraph (c)(4)(i) of this section) in all allowance allocation requests accepted under paragraph (c)(4)(i) of this section for the control period.

   (iii) If the amount of CAIR NOXOzone Season allowances in the new unit set-aside for the control period is greater than or equal to the sum under paragraph (c)(4)(ii) of this section, then the Administrator will allocate the amount of CAIR NOXOzone Season allowances requested (as adjusted under paragraph (c)(4)(i) of this section) to each CAIR NOXOzone Season unit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section.

   (iv) If the amount of CAIR NOXOzone Season allowances in the new unit set-aside for the control period is less than the sum under paragraph (c)(4)(ii) of this section, then the Administrator will allocate to each CAIR NOXOzone Season unit covered by an allowance allocation request accepted under paragraph (c)(4)(i) of this section the amount of the CAIR NOXOzone Season allowances requested (as adjusted under paragraph (c)(4)(i) of this section), multiplied by the amount of CAIR NOXOzone Season allowances in the new unit set-aside for the control period, divided by the sum determined under paragraph (c)(4)(ii) of this section, and rounded to the nearest whole allowance as appropriate.

   (v) The Administrator will notify each CAIR designated representative that submitted an allowance allocation request of the amount of CAIR NOXOzone Season allowances (if any) allocated for the control period to the CAIR NOXOzone Season unit covered by the request.

   (d) If, after completion of the procedures under paragraph (c)(4) of this section for a control period, any unallocated CAIR NOXOzone Season allowances remain in the new unit set-aside under paragraph (c) of this section for a State for the control period, the Administrator will allocate to each CAIR NOXOzone Season unit that was allocated CAIR NOXOzone Season allowances under paragraph (b) of this section an amount of CAIR NOXOzone Season allowances equal to the total amount of such remaining unallocated CAIR NOXOzone Season allowances, multiplied by the unit's allocation under paragraph (b) of this section, divided by 95 percent for a control period during 2009 through 2014, and 97 percent for a control period during 2015 and thereafter, of the amount of tons of NOXemissions in the State trading budget for such State under Sec. 97.340, and rounded to the nearest whole allowance as appropriate.

   (e) If the Administrator determines that CAIR NOXOzone Season allowances were allocated under paragraphs (a) and (b) of this section, paragraphs (a) and (c) of this section, or paragraph (d) or (e) of this section for a control period and that the recipient of the allocation is not actually a CAIR NOXOzone Season unit under Sec. 97.304 in such control period, then the Administrator will notify the CAIR designated representative and will act in accordance with the following procedures:

   (1) Except as provided in paragraph (e)(2) or (3) of this section, the Administrator will not record such CAIR NOXOzone Season allowances under Sec. 97.353.

   (2) If the Administrator already recorded such CAIR NOX Ozone Season allowances under Sec. 97.353 and if the Administrator makes such determinations before making deductions for the source that includes such recipient under Sec. 97.354(b) for the control period, then the Administrator will deduct from the account in which such CAIR NOXOzone Season allowances were recorded under Sec. 97.353 an amount of CAIR NOXOzone Season allowances allocated for the same or a prior control period equal to the amount of such already recorded CAIR NOXOzone Season allowances. The CAIR designated representative shall ensure that there are sufficient CAIR NOXOzone Season allowances in such account for completion of the deduction.

   (3) If the Administrator already recorded such CAIR NOX Ozone Season allowances under Sec. 97.353 and if the Administrator makes such determinations after making deductions for the source that includes such recipient under Sec. 97.354(b) for the control period, then the Administrator will apply paragraph (e)(1) or (2) of this section, as appropriate, to any subsequent control period for which CAIR NOXOzone Season allowances were allocated to such recipient.

   (4) The Administrator will transfer the CAIR NOXOzone Season allowances that are not recorded, or that are deducted, in accordance with paragraphs (e)(1), (2), and (3) of this section to a new unit set-aside for the State in which such recipient is located.

   1. Interim review of monitoring plan. The permitting authority and the Administrator will determine, on an interim basis, the sufficiency of the monitoring plan accompanying the initial application for a CAIR opt-in permit under Sec. 97.383. A monitoring plan is sufficient, for purposes of interim review, if the plan appears to contain information demonstrating that the NOXemissions rate and heat input of the unit and all other applicable parameters are monitored and reported in accordance with subpart HH of this part. A determination of sufficiency shall not be construed as acceptance or approval of the monitoring plan.

      (b) Monitoring and reporting. (1)(i) If the permitting authority and the Administrator determines that the monitoring plan is sufficient under paragraph (a) of this section, the owner or operator shall monitor and report the NOXemissions rate and the heat input of the unit and all other applicable parameters, in accordance with subpart HHHH of this part, starting on the date of certification of the appropriate monitoring systems under subpart HH of this part and continuing until a CAIR opt-in permit is denied under Sec. 97.384(f) or, if a CAIR opt-in permit is issued, the date and time when the unit is withdrawn from the CAIR NOXOzone Season Trading Program in accordance with Sec. 97.386.

      (ii) The monitoring and reporting under paragraph (b)(1)(i) of this section shall include the entire control period immediately before the date on which the unit enters the CAIR NOXOzone Season Trading Program under Sec. 97.384(g), during which period monitoring system availability must not be less than 90 percent under subpart HHHH of this part and the unit must be in full compliance with any applicable State or Federal emissions or emissions-related requirements.

      (2) To the extent the NOXemissions rate and the heat input of the unit are monitored and reported in accordance with subpart HH of this part for one or more control periods, in addition to the control period under paragraph (b)(1)(ii) of this section, during which control periods monitoring system availability is not less than 90 percent under subpart HHHH of this part and the unit is in full compliance with any applicable State or Federal emissions or emissions- related requirements and which control periods begin not more than 3 years before the unit enters the CAIR NOXOzone Season Trading Program under Sec. 97.384(g), such information shall be used as provided in paragraphs (c) and (d) of this section.

      (c) Baseline heat input. The unit's baseline heat rate shall equal:

      (1) If the unit's NOXemissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's total heat input (in mmBtu) for the control period; or

      (2) If the unit's NOXemissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, the average of the amounts of the unit's total heat input (in mmBtu) for the control periods under paragraphs (b)(1)(ii) and (b)(2) of this section.

      (d) Baseline NOX emission rate. The unit's baseline NOX emission rate shall equal:

      (1) If the unit's NOXemissions rate and heat input are monitored and reported for only one control period, in accordance with paragraph (b)(1) of this section, the unit's NOXemissions rate (in lb/mmBtu) for the control period;

      (2) If the unit's NOXemissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit does not have add-on NOXemission controls during any such control periods, the average of the amounts of the unit's NOX emissions rate (in lb/mmBtu) for the control periods under paragraphs (b)(1)(ii) and (b)(2) of this section; or

      (3) If the unit's NOXemissions rate and heat input are monitored and reported for more than one control period, in accordance with paragraphs (b)(1) and (2) of this section, and the unit has add-on NOXemission controls during any such control periods, the average of the amounts of the unit's NOXemissions rate (in lb/mmBtu) for such control periods during which the unit has add-on NOXemission controls.

      (e) Issuance of CAIR opt-in permit. After calculating the baseline heat input and the baseline NOXemissions rate for the unit under paragraphs (c) and (d) of this section and if the permitting authority determines that the CAIR designated representative shows that the unit meets the requirements for a CAIR NOXOzone Season opt-in unit in Sec. 97.380 and meets the elements certified in Sec. 97.383(a)(2), the permitting authority will issue a CAIR opt-in permit. The permitting authority will provide a copy of the CAIR opt-in permit to the Administrator, who will then establish a compliance account for the source that includes the CAIR NOXOzone Season opt-in unit unless the source already has a compliance account.

      (f) Issuance of denial of CAIR opt-in permit. Notwithstanding paragraphs (a) through (e) of this section, if at any time before issuance of a CAIR opt-in permit for the unit, the permitting authority determines that the CAIR designated representative fails to show that the unit meets the requirements for a CAIR NOXOzone Season opt-in unit in Sec. 97.380 or meets the elements certified in Sec. 97.383(a)(2), the permitting authority will issue a denial of a CAIR opt-in permit for the unit.
