Approval of Implementation Plans; North Carolina: Clean Air Interstate Rule

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

SUMMARY: EPA is approving revisions to the North Carolina State Implementation Plan (SIP) submitted by the State of North Carolina, through the North Carolina Department of Environmental and Natural Resources on August 7, 2006. These revisions incorporate provisions related to the implementation of EPA's Clean Air Interstate Rule (CAIR), promulgated on May 12, 2005, and subsequently revised on April 28, 2006, and December 13, 2006, and the CAIR Federal Implementation Plan (FIP) concerning sulfur dioxide (SO2), nitrogen oxides (NOX) annual, and NOXozone season emissions for the State of North Carolina, promulgated on April 28, 2006, and subsequently revised December 13, 2006. EPA is not making any changes to the CAIR FIP, but is amending, to the extent EPA approves North Carolina's SIP revisions, the appropriate appendices in the CAIR FIP trading rules simply to note that approval.

On July 3, 2007, North Carolina requested that EPA only act on a portion of the August 7, 2006, submittal as an abbreviated SIP. Consequently, EPA is approving the abbreviated SIP revisions that address the methodology to be used to allocate annual and ozone season NOXallowances to existing and new units under the CAIR FIPs and CAIR FIP opt-in provisions.

DATES: This direct final rule is effective December 4, 2007 without further notice, unless EPA receives adverse comment by November 5, 2007. If EPA receives such comments, it will publish a timely withdrawal of the direct final rule in the Federal Register and inform the public that the rule will not take effect.

   1. What Action Is EPA Taking?

      CAIR SIP Approval

      EPA is approving revisions to the North Carolina SIP, initially submitted on August 7, 2006, and revised on July 3, 2007, that would modify the application of certain provisions of the CAIR FIP concerning SO2, NOXannual, and NOXozone season emissions. (As discussed below, this less comprehensive CAIR SIP is termed an abbreviated SIP.) North Carolina is subject to the CAIR FIPs that implement the CAIR requirements by requiring certain electric generating units (EGUs) to participate in the EPA-administered Federal CAIR SO2, NOXannual, and NOXozone season cap-and-trade programs. The SIP revisions provide a methodology for allocating NOXallowances for the NOXannual and NOXozone season trading programs. The CAIR FIPs provide that this methodology, if approved by EPA, will be used to allocate NOXallowances to sources in North Carolina, instead of the federal allocation methodology otherwise provided in the FIP. The SIP revisions also allow for individual units not otherwise subject to the CAIR SO2, NOXannual, and NOXozone season trading programs to opt into such trading programs in accordance with opt-in provisions in the CAIR FIPs. Once approved, the SIP revisions will provide for the recordation of NOXannual and ozone season allowances using the allocations determined by North Carolina, including the NOXannual new unit growth pool for 2009-2014 in North Carolina's rule minus one ton, i.e., 2,610 tons and will allow certain units to opt into, and be allocated allowances under, the opt-in provisions in the CAIR FIPs. Consistent with the flexibility provided in the FIPs, these provisions, if approved, will be also be used to replace or supplement, as appropriate, the corresponding provisions in the CAIR FIPs for North Carolina. EPA is not making any changes to the CAIR FIP, but is amending, to the extent EPA approves North Carolina's SIP revision, the appropriate appendices in the CAIR FIP trading rules simply to note that approval.

      EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed.

   2. What Is the Regulatory History of the CAIR and the CAIR FIPs?

      The CAIR was published by EPA on May 12, 2005 (70 FR 25162). In this rule, EPA determined that 28 States and the District of Columbia contribute significantly to nonattainment and interfere with maintenance of the national ambient air quality standards (NAAQS) for fine particulates (PM2.5) and/or 8-hour ozone in downwind States in the eastern part of the country. As a result, EPA required those upwind States to revise their SIPs to include control measures that reduce emissions of SO2, which is a precursor to PM2.5formation, and/or NOX, which is a precursor to both ozone and PM2.5formation. For jurisdictions that contribute significantly to downwind PM2.5nonattainment, CAIR sets annual State-wide emission reduction requirements (i.e., budgets) for SO2and annual State-wide emission reduction requirements for NOX. Similarly, for jurisdictions that contribute significantly to 8-hour ozone nonattainment, CAIR sets State-wide emission reduction requirements for NOXfor the ozone season (May 1st to September 30th). Under CAIR, States may implement these emission budgets by participating in the EPA- administered cap-and-trade programs or by adopting any other control measures.

      CAIR explains to subject states what must be included in SIPs to address the requirements of section 110(a)(2)(D) of the Clean Air Act (CAA) with regard to interstate transport with respect to the 8-hour ozone and PM2.5NAAQS. EPA made national findings, effective May 25, 2005, that the States had failed to submit SIPs meeting the requirements of section 110(a)(2)(D). The SIPs were due in July 2000, 3 years after the promulgation of the 8-hour ozone and PM2.5 NAAQS. These findings started a 2-year clock for EPA to promulgate a FIP to address the requirements of section 110(a)(2)(D). Under CAA section 110(c)(1), EPA may issue a FIP anytime after such findings are made and must do so within two years unless, a SIP revision correcting the deficiency is approved by EPA before the FIP is promulgated.

      On April 28, 2006, EPA promulgated FIPs for all States covered by CAIR in order to ensure the emissions reductions required by CAIR are achieved on schedule. Each CAIR State is subject to the FIPs until the State fully adopts, and EPA approves, a SIP revision meeting

      [[Page 56916]]

      the requirements of CAIR. The CAIR FIPs require certain EGUs to participate in the EPA-administered CAIR SO2, NOX annual, and NOXozone-season model trading programs, as appropriate. The CAIR FIP SO2, NOXannual, and NOXozone season trading programs impose essentially the same requirements as, and are integrated with, the respective CAIR SIP trading programs. The integration of the CAIR FIP and SIP trading programs means that these trading programs will work together to create effectively a single trading program for each regulated pollutant (SO2, NOXannual, and NOXozone season) in all States covered by CAIR FIP or SIP trading program for that pollutant. The CAIR FIPs also allow States to submit abbreviated SIP revisions that, if approved by EPA, will automatically replace or supplement the corresponding CAIR FIP provisions (e.g., the methodology for allocating NOXallowances to sources in the State), while the CAIR FIP remains in place for all other provisions.

      On April 28, 2006, EPA published two more CAIR-related final rules that added the States of Delaware and New Jersey to the list of States subject to CAIR for PM2.5and announced EPA's final decisions on reconsideration of five issues without making any substantive changes to the CAIR requirements.

   3. What Are the General Requirements of CAIR and the CAIR FIPs?

      CAIR establishes State-wide emission budgets for SO2and NOXand is to be implemented in two phases. The first phase of NOXreductions starts in 2009 and continues through 2014, while the first phase of SO2reductions starts in 2010 and continues through 2014. The second phase of reductions for both NOXand SO2starts in 2015 and continues thereafter. CAIR requires States to implement the budgets by either: (1) Requiring EGUs to participate in the EPA-administered cap-and-trade programs, or (2) adopting other control measures of the State's choosing and demonstrating that such control measures will result in compliance with the applicable State SO2and NOX budgets.

      The May 12, 2005 and April 28, 2006 CAIR rules provide model rules that States must adopt (with certain limited changes, if desired) if they want to participate in the EPA-administered trading programs.

      With two exceptions, only States that choose to meet the requirements of CAIR through methods that exclusively regulate EGUs are allowed to participate in the EPA-administered trading programs. One exception is for States that adopt the opt-in provisions of the model rules to allow non-EGUs individually to opt into the EPA-administered trading programs. The other exception is for States that include all non-EGUs from their NOXSIP Call trading programs in their CAIR NOXozone season trading programs.

   4. What Are the Types of CAIR SIP Submittals?

      States have the flexibility to choose the type of control measures they will use to meet the requirements of CAIR. EPA anticipates that most States will choose to meet the CAIR requirements by selecting an option that requires EGUs to participate in the EPA-administered CAIR cap-and-trade programs. For such States, EPA has provided two approaches for submitting and obtaining approval for CAIR SIP revisions. States may submit full SIP revisions that adopt the model CAIR cap-and-trade rules. If approved, these SIP revisions will fully replace the CAIR FIPs. Alternatively, States may submit abbreviated SIP revisions. These SIP revisions will not replace the CAIR FIPs; however, the CAIR FIPs provide that, when approved, the provisions in these abbreviated SIP revisions will be used instead of or in conjunction with, as appropriate, the corresponding provisions of the CAIR FIPs (e.g., the NOXallowance allocation methodology).

      A State submitting an abbreviated SIP revision may submit limited SIP revisions to tailor the CAIR FIP cap-and-trade programs to the State submitting the revision. Specifically, an abbreviated SIP revision may establish certain applicability and allowance allocation provisions that, the CAIR FIPs provide, will be used instead of or in conjunction with the corresponding provisions in the CAIR FIP rules in that State. Specifically, the abbreviated SIP revisions may:

1. Include NOXSIP Call trading sources that are not EGUs under CAIR in the CAIR FIP NOXozone season trading program;

2. Provide for allocation of NOXannual or ozone season allowances by the State, rather than the Administrator of the EPA or the Administrator's duly authorized representative (Administrator), and using a methodology chosen by the State;

3. Provide for allocation of NOXannual allowances from the Compliance Supplement Pool (CSP) by the State, rather than by the Administrator, and using the State's choice of allowed, alternative methodologies; or

4. Allow units that are not otherwise CAIR units to opt individually into the CAIR FIP cap-and-trade programs under the opt-in provisions in the CAIR FIP rules.

   With approval of an abbreviated SIP revision, the CAIR FIP remains in place, as tailored to sources in the State by the approved SIP revisions.

   Abbreviated SIP revisions can be submitted in lieu of, or as part of, CAIR full SIP revisions. States may want to designate part of their full SIP as an abbreviated SIP for EPA to act on first when the timing of the State's submission might not provide EPA with sufficient time to approve the full SIP prior to the deadline for recording NOX allocations. This will help ensure that the elements of the trading programs where flexibility is allowed are implemented according to the State's decisions. Submission of an abbreviated SIP revision does not preclude future submission of a CAIR full SIP revision. In this case, the July 3, 2007, submittal from North Carolina has been submitted as an abbreviated SIP revision.

   5. Analysis of North Carolina's CAIR SIP Submittal

   1. State Budgets for Allowance Allocations

      The CAIR NOXannual and ozone season budgets were developed from historical heat input data for EGUs. Using these data, EPA calculated annual and ozone season regional heat input values, which were multiplied by 0.15 pounds per million British thermal units (lb/mmBtu), for phase 1, and 0.125 lb/mmBtu, for phase 2, to obtain regional NOXbudgets for 2009-2014 and for 2015 and thereafter, respectively. EPA derived the State NOXannual and ozone season budgets from the regional budgets using State heat input data adjusted by fuel factors.

      The CAIR State SO2budgets were derived by discounting the tonnage of emissions authorized by annual allowance allocations under the Acid Rain Program under title IV of the CAA. Under CAIR, each allowance allocated under the Acid Rain Program for the years in phase 1 of CAIR (2010 through 2014) authorizes 0.50 ton of SO2 emissions in the CAIR trading program, and each Acid Rain Program allowance allocated for the years in phase 2 of CAIR (2015 and thereafter) authorizes 0.35 ton of SO2emissions in the CAIR trading program.

      The CAIR FIPs established the budgets for North Carolina as 62,183 (2009-2014) and 51,819 (2015-thereafter) tons for NOXannual emissions, 28,392 (2009-2014) and

      [[Page 56917]]

      23,660 (2015-thereafter) tons for NOXozone season emissions, and 137,342 (2010-2014) and 96,139 (2015-thereafter) tons for SO2emissions. North Carolina's SIP revision, being approved in this action, does not affect these budgets, which are total amounts of allowances available for allocation for each year under the EPA-administered cap-and-trade programs under the CAIR FIPs. In short, the abbreviated SIP revision only affects allocations of allowances under the established budgets.

   2. CAIR Cap-and-Trade Programs

      The CAIR NOXannual and ozone season FIPs both largely mirror the structure of the NOXSIP Call model trading rule in 40 CFR part 96, subparts A through I. While the provisions of the NOXannual and ozone season FIPs are similar, there are some differences. For example, the NOXannual FIP (but not the NOXozone season FIP) provides for a CSP, which is discussed below and under which allowances may be awarded for early reductions of NOXannual emissions. As a further example, the NOX ozone season FIP reflects the fact that the CAIR NOXozone season trading program replaces the NOXSIP Call trading program after the 2008 ozone season and is coordinated with the NOXSIP Call program. The NOXozone season FIP provides incentives for early emissions reductions by allowing banked, pre-2009 NOXSIP Call allowances to be used for compliance in the CAIR NOXozone season trading program. In addition, States have the option of continuing to meet their NOXSIP Call requirement by participating in the CAIR NOXozone season trading program and including all their NOXSIP Call trading sources in that program.

      The provisions of the CAIR SO2FIP are also similar to the provisions of the NOXannual and ozone season FIPs. However, the SO2FIP is coordinated with the ongoing Acid Rain SO2cap-and-trade program under CAA title IV. The SO2FIP uses the title IV allowances for compliance, with each allowance allocated for 2010-2014 authorizing only 0.50 ton of emissions and each allowance allocated for 2015 and thereafter authorizing only 0.35 ton of emissions. Banked title IV allowances allocated for years before 2010 can be used at any time in the CAIR SO2cap-and-trade program, with each such allowance authorizing 1 ton of emissions. Title IV allowances are to be freely transferable among sources covered by the Acid Rain Program and sources covered by the CAIR SO2cap-and-trade program.

      EPA used the CAIR model trading rules as the basis for the trading programs in the CAIR FIPs. The CAIR FIP trading rules are virtually identical to the CAIR model trading rules, with changes made to account for federal rather than State implementation. The CAIR model SO2, NOXannual, and NOXozone season trading rules and the respective CAIR FIP trading rules are designed to work together as integrated SO2, NOXannual, and NOXozone season trading programs.

      North Carolina is subject to the CAIR FIPs for ozone and PM2.5 and the CAIR FIP trading programs for SO2, NOX annual, and NOXozone season which apply to sources in North Carolina. Consistent with the flexibility it gives to States, the CAIR FIPs provide that States may submit abbreviated SIP revisions that will replace or supplement, as appropriate, certain provisions of the CAIR FIP trading programs. The July 3, 2007, submission of North Carolina is such an abbreviated SIP revision.

   3. Applicability Provisions for Non-Electric Generating Units (EGUs) NOXSIP Call Sources

      In general, the CAIR FIP trading programs apply to 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 megawatt electrical (MWe) producing electricity for sale.

      States have the option of bringing in, for the CAIR NOX ozone season program only, those units in the State's NOX SIP Call trading program that are not EGUs as defined under CAIR. EPA advises States exercising this option to use provisions for applicability that are substantively identical to the provisions in 40 CFR 96.304 and add the applicability provisions in the State's NOX SIP Call trading rule for non-EGUs to the applicability provisions in 40 CFR 96.304 in order to include in the CAIR NOXozone season trading program all units required to be in the State's NOX SIP Call trading program that are not already included under 40 CFR 96.304. Under this option, the CAIR NOXozone season program must cover all large industrial boilers and combustion turbines, as well as any small EGUs (i.e. units serving a generator with a nameplate capacity of 25 MWe or less), that the State currently requires to be in the NOXSIP Call trading program.

      Consistent with the flexibility given to States in the CAIR FIP, North Carolina has not chosen, in the abbreviated SIP revision being approved in today's action, to expand the applicability provisions of the CAIR NOXozone season trading program to include all non-EGUs in the State's NOXSIP Call trading program. EPA notes that North Carolina has indicated that it intends to submit subsequently a full SIP revision that expands the applicability provisions of the CAIR NOXozone season trading program in this manner.

   4. NOX Allowance Allocations

      Under the NOXallowance allocation methodology in the CAIR model trading rules and in the CAIR FIP, NOXannual and ozone season allowances are allocated to units that have operated for five years, based on heat input data from a three-year period that are adjusted for fuel type by using fuel factors of 1.0 for coal, 0.6 for oil, and 0.4 for other fuels. The CAIR model trading rules and the CAIR FIP also provide a new unit set-aside from which units without five years of operation are allocated allowances based on the units' prior year emissions.

      The CAIR FIP provides States the flexibility to establish a different NOXallowance allocation methodology that will be used to allocate allowances to sources in the States if certain requirements are met concerning the timing of submission of units' allocations to the Administrator for recordation and the total amount of allowances allocated for each control period. In adopting alternative NOXallowance allocation methodologies, States have flexibility with regard to:

1. The cost to recipients of the allowances, which may be distributed for free or auctioned;

2. The frequency of allocations;

3. The basis for allocating allowances, which may be distributed, for example, based on historical heat input or electric and thermal output; and

4. The use of allowance set-asides and, if used, their size.

   Consistent with the flexibility given to States in the CAIR FIPs, North Carolina has chosen to replace the provisions of the CAIR NOXannual FIP concerning the allocation of NOX annual allowances with its own methodology. North Carolina has chosen to distribute NOXannual allowances by submitting the table adopted in 15A NCAC 02D .2403(a), which establishes the North Carolina CAIR NOXannual allocations for existing units. In addition, North Carolina has chosen to use the same methodology as in the CAIR FIP to allocate allowances for 2,610 and 1,131 tons of NOX to new unit growth for 2009-2014 and for 2015 and thereafter, respectively. Under 40 CFR 51.123(p)(1)(ii)(C), the State permitting

   [[Page 56918]]

   authority must submit CAIR NOXannual allowance allocations for new units determined under an abbreviated SIP revision by October 31 of each year for which the allowances are allocated. North Carolina's rule does not address the question of when new unit allocations will be submitted to the Administrator and does not adopt either the timing set forth in 40 CFR 51.123(p)(1)(ii)(C), or any alternative timing, for the allocation submissions. However, in a letter dated September 18, 2007, North Carolina stated that its submissions of new unit allocations to the Administrator will meet the timing requirement in 40 CFR 51.123(p)(1)(ii)(C). In light of North Carolina's express intent to meet the timing requirements for submissions of new unit allocations, EPA is interpreting North Carolina's rule to require that new unit allocations be submitted to the Administrator by October 31 of each year for which new unit allocations are made.

   Consistent with the flexibility given to States in the CAIR FIPs, North Carolina has chosen to replace the provisions of the CAIR NOXozone season FIP concerning allowance allocations with their own methodology. North Carolina has chosen to distribute NOXozone season allowances by submitting the table adopted in 15A NCAC 02D .2405(a), which establishes the North Carolina CAIR NOXozone season allocations for existing units. In addition, North Carolina has chosen to use the same methodology as in the CAIR FIP to allocate allowances for 1,206 and 531 tons of NOXto new units for 2009-2014 and for 2015 and thereafter, respectively. Under 40 CFR 51.123(ee)(2)(ii)(D), the State permitting authority must submit CAIR NOXozone season allowance allocations for new units determined under an abbreviated SIP revision by July 31 of each year for which the allowances are allocated. North Carolina's rule does not address the question of when new unit allocations will be submitted to the Administrator and does not adopt either the timing set forth in 40 CFR 51.123(ee)(2)(ii)(D), or any alternative timing, for the allocation submissions. However, in a letter dated September 18, 2007, North Carolina stated that its submissions of new unit allocations to the Administrator will meet the timing requirement in 40 CFR 51.123(ee)(2)(ii)(D). In light of North Carolina's express intent to meet the timing requirements for submissions of new unit allocations, EPA is interpreting North Carolina's rule to require that new unit allocations be submitted to the Administrator by July 31 of each year for which new unit allocations are made.

   5. Allocation of NOX Allowances From the Compliance Supplement Pool (CSP)

      The CSP provides an incentive for early reductions in NOXannual emissions. The CSP consists of 200,000 CAIR NOXannual allowances of vintage 2009 for the entire CAIR region, and a State's share of the CSP is based upon the State's share of the projected emission reductions under CAIR. States may distribute CSP allowances, one allowance for each ton of early reduction, to sources that make NOXreductions during 2007 or 2008 beyond what is required by any applicable State or Federal emission limitation. States also may distribute CSP allowances based upon a demonstration of need for an extension of the 2009 deadline for implementing emission controls.

      The CAIR NOXannual FIP establishes specific methodologies for allocations of CSP allowances. States may choose an allowed, alternative CSP allocation methodology to be used to allocate CSP allowances to sources in those States.

      Consistent with the flexibility given to States in the FIP, North Carolina has not chosen to modify the provisions of the CAIR NOXannual FIP concerning the allocation of allowances from the CSP, since the State does not have any allowances available to allocate under the CSP provisions.

   6. Individual Opt-In Units

      The opt-in provisions allow for certain non-EGUs (i.e., boilers, combustion turbines, and other stationary fossil-fuel-fired devices) that do not meet the applicability criteria for a CAIR trading program to participate voluntarily in (i.e., opt into) the CAIR trading program. A non-EGU may opt into one or more of the CAIR trading programs. In order to qualify to opt into a CAIR trading program, a unit must vent all emissions through a stack and be able to meet monitoring, recordkeeping, and recording requirements of 40 CFR part 75. The owners and operators seeking to opt a unit into a CAIR trading program must apply for a CAIR opt-in permit. If the unit is issued a CAIR opt-in permit, the unit becomes a CAIR unit, is allocated allowances, and must meet the same allowance-holding and emissions monitoring and reporting requirements as other units subject to the CAIR trading program. The opt-in provisions provide for two methodologies for allocating allowances for opt-in units, one methodology that applies to opt-in units in general and a second methodology that allocates allowances only to opt-in units that the owners and operators intend to repower before January 1, 2015.

      States have several options concerning the opt-in provisions. The rules for each of the CAIR FIP trading programs include opt-in provisions that are essentially the same as those in the respective CAIR SIP model rules, except that the CAIR FIP opt-in provisions become effective in a State only if the State's abbreviated SIP revision adopts the opt-in provisions. The State may adopt the opt-in provisions entirely or may adopt them but exclude one of the allowance allocation methodologies. The State also has the option of not adopting any opt-in provisions in the abbreviated SIP revision and thereby providing for the CAIR FIP trading program to be implemented in the State without the ability for units to opt into the program.

      Consistent with the flexibility given to States in the FIPs, North Carolina has chosen to allow non-EGUs meeting certain requirements to participate in the CAIR NOXannual trading program. The North Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart II of the CAIR NOX annual trading program.

      Consistent with the flexibility given to States in the FIPs, North Carolina has chosen to permit non-EGUs meeting certain requirements to participate in the CAIR NOXozone season trading program. The North Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart IIII of the CAIR NOXozone season trading program.

      Consistent with the flexibility given to States in the FIPs, North Carolina has chosen to allow certain non-EGUs to opt into the CAIR SO2trading program. The North Carolina rule allows for both of the opt-in allocation methods as specified in 40 CFR part 97 Subpart III of the CAIR SO2trading program.

      6. Final Action

         EPA is approving North Carolina's abbreviated CAIR SIP revisions submitted on July 3, 2007. North Carolina is covered by the CAIR FIPs, which requires participation in the EPA-administered CAIR FIP cap-and- trade programs for SO2, NOXannual, and NOXozone season emissions. Under these abbreviated SIP revisions and consistent with the flexibility given to States in the FIPs, North Carolina adopts provisions for allocating allowances under the CAIR FIP NOXannual and ozone season trading programs, including new unit provisions. EPA is approving North

         [[Page 56919]]

         Carolina's CAIR NOXannual and ozone season allocation provisions (interpreted as discussed above) for units subject to the CAIR trading programs under the current CAIR FIP NOXannual and ozone season applicability provisions. In addition, North Carolina adopts in the abbreviated SIP revision provisions that allow for individual non-EGUs to opt into the CAIR FIP SO2, NOXannual, and NOXozone season cap-and-trade programs. EPA is approving North Carolina's allowing for opt-in units and therefore the application of the opt-in provisions in these CAIR FIP trading programs to units in North Carolina.

         As provided for in the CAIR FIPs, these provisions in the abbreviated SIP revision will replace or supplement the corresponding provisions of the CAIR FIPs in North Carolina. The abbreviated SIP revision meets the applicable requirements in 40 CFR 51.123(p) and (ee), with regard to NOXannual and NOXozone season emissions, and 40 CFR 51.124(r), with regard to SO2 emissions. EPA is not making any changes to the CAIR FIP, but is amending, to the extent EPA approves North Carolina's SIP revision, the appropriate appendices in the CAIR FIP trading rules simply to note that approval.

         EPA is approving the aforementioned changes to the SIP. EPA is publishing this rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. However, in the proposed rules section of this Federal Register publication, EPA is publishing a separate document that will serve as the proposal to approve the SIP revision should adverse comments be filed. This rule will be effective December 4, 2007 without further notice unless the Agency receives adverse comments by November 5, 2007.

         If the EPA receives such comments, then EPA will publish a document withdrawing the final rule and informing the public that the rule will not take effect. All public comments received will then be addressed in a subsequent final rule based on the proposed rule. EPA will not institute a second comment period. Parties interested in commenting should do so at this time. If no such comments are received, the public is advised that this rule will be effective on December 4, 2007 and no further action will be taken on the proposed rule.

      7. Statutory and Executive Order Reviews

         Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ``significant regulatory action'' and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action merely approves State law as meeting Federal requirements and imposes no additional requirements beyond those imposed by State law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under State law and does not impose any additional enforceable duty beyond that required by State law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

         This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does 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 (64 FR 43255, August 10, 1999). This action merely approves a State rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045 ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because it is not economically significant.

         In reviewing SIP submissions, EPA's role is to approve State choices, provided that they meet the criteria of the CAA. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

         The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a ``major rule'' as defined by 5 U.S.C. 804(2).

         Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by December 4, 2007. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2)).
