Air Plan Approval; TN; Reasonably Available Control Measures and Redesignation for the TN Portion of the Chattanooga 1997 Annual PM2.5 Nonattainment Area
AGENCY: Environmental Protection Agency.
ACTION: Proposed rule; supplemental.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is proposing two separate but related actions pertaining to the Tennessee portion of the Chattanooga nonattainment area for the 1997 annual fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) (hereinafter referred to as the ``Chattanooga TN-GA-AL Area'' or ``Area''). First, EPA is proposing to approve the portion of the attainment plan state implementation plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), on October 15, 2009, that addresses reasonably available control measures (RACM), including reasonably available control technology (RACT), for the Tennessee portion of the Area. EPA is not proposing to act on the portions of the SIP revision that are unrelated to RACM. Second, EPA is supplementing the Agency's March 27, 2015, proposed approval of Tennessee's November 13, 2014, redesignation request for the Tennessee portion of the Area by proposing that approval of the RACM portion of the aforementioned SIP revision satisfies the applicable RACM requirements for redesignation under the Clean Air Act (CAA or Act).

SUPPLEMENTARY INFORMATION:

Background
On July 18, 1997, EPA promulgated the first air quality standards for PM2.5. EPA promulgated an annual standard at a level of 15 micrograms per cubic meter (mug/m\3\) (based on a 3-year average of annual mean PM2.5 concentrations) and a 24-hour standard of 65 mug/m\3\ (based on a 3-year average of the 98th percentile of 24-hour concentrations). See 62 FR 36852. On January 5, 2005, and supplemented on April 14, 2005, EPA designated Hamilton County in Tennessee, in association with counties in Alabama and Georgia in the Chattanooga TN-GA-AL Area, as nonattainment for the 1997 Annual PM2.5 NAAQS. See 70 FR 944 and 70 FR 19844, respectively. Designation of an area as nonattainment for PM2.5 starts the process for a state to develop and submit to EPA an attainment plan SIP revision under title I, part D of the CAA. This SIP revision must include, among other elements, a demonstration of how the NAAQS will be attained in the nonattainment area as expeditiously as practicable, but no later than the attainment date required by the CAA.
EPA designated all 1997 PM2.5 NAAQS areas under title I, part D, subpart 1 (hereinafter ``Subpart 1''). Subpart 1 contains the general requirements for nonattainment areas for criteria pollutants and is less prescriptive than the other subparts of title I, part D. On April 25, 2007, EPA promulgated a rule, codified at 40 CFR part 51, subpart Z, to implement the 1997 PM2.5 NAAQS under Subpart 1 (hereinafter referred to as the ``1997 PM2.5 Implementation Rule'').\1\ See 72 FR 20586. On October 15, 2009, Tennessee submitted an attainment plan SIP revision pursuant to Subpart 1 and the 1997 PM2.5 Implementation Rule that addressed RACM and contained a reasonable further progress (RFP) plan, base-year and attainment-year emissions inventories, and contingency measures for the Area.
---------------------------------------------------------------------------
\1\ On January 4, 2013, in Natural Resources Defense Council v. EPA, 706 F.3d 428 (D.C. Cir. 2013), the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) found that EPA erred in implementing the 1997 PM2.5 NAAQS pursuant solely to the general implementation provisions of Subpart 1 rather than the particulate matter-specific provisions of title I, part D, subpart 4. The court remanded both the 1997 PM2.5 Implementation Rule and the final rule entitled ``Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM2.5)'' (73 FR 28321, May 16, 2008) to EPA to address this error.
---------------------------------------------------------------------------
On May 31, 2011 (76 FR 31239), EPA published a final determination that the Chattanooga TN-GA-AL Area had attained the 1997 Annual PM2.5 NAAQS based upon quality-assured and certified ambient air monitoring data for the 2007-2009 time period. In that determination and in accordance with the 1997 PM2.5 Implementation Rule at 40 CFR 51.1004(c), EPA suspended the requirements for the Chattanooga TN-GA-AL Area to submit attainment demonstrations and associated RACM, RFP plans, contingency measures, and other planning SIPs related to attainment of the 1997 Annual PM2.5 NAAQS, so long as the Area continues to attain the 1997 Annual PM2.5 NAAQS. See 40 CFR 52.2231(c); 76 FR 31239.
Tennessee submitted a request to EPA on November 13, 2014, to redesignate the State's portion of the Chattanooga TN-GA-AL Area to attainment for the 1997 Annual PM2.5 NAAQS and to approve a SIP revision containing a maintenance plan for the Tennessee portion of the Area. EPA proposed to approve the redesignation request and the related SIP revision in an action signed on March 11, 2015, based, in part, on the Agency's longstanding interpretation that Subpart 1 nonattainment planning requirements, including RACM, are not ``applicable'' for purposes of CAA section 107(d)(3)(E)(ii) once an area is attaining the NAAQS and, therefore, need not be approved into the SIP before EPA can redesignate the area. See 80 FR 16331 (March 27, 2015).
On March 18, 2015, the United States Court of Appeals for the Sixth Circuit (Sixth Circuit) issued an opinion in Sierra Club v. EPA, 781 F.3d 299 (6th Cir. 2015), that is inconsistent with this longstanding interpretation regarding section 107(d)(3)(E)(ii). In its decision, the Court vacated EPA's redesignation of the Indiana and Ohio portions of the Cincinnati-Hamilton nonattainment area to attainment for the 1997 PM2.5 NAAQS because EPA had not yet approved Subpart 1 RACM for the Cincinnati Area into the Indiana and Ohio SIPs.\2\ The Court concluded that ``a State seeking redesignation `shall provide for the implementation' of RACM/RACT, even if those measures are not strictly necessary to demonstrate attainment with the PM2.5 NAAQS . . . . If a State has not done so, EPA cannot `fully approve' the area's SIP, and redesignation to attainment status is improper.'' Sierra Club, 781 F.3d at 313.
---------------------------------------------------------------------------
\2\ The Court issued an amended decision on July 14, 2015, revising some of the legal aspects of the Court's analysis of the relevant statutory provisions (section 107(d)(3)(E)(ii) and section 172(c)(1)) but maintaining its prior holding that section 172(c)(1) ``unambiguously requires implementation of RACM/RACT prior to redesignation . . . even if those measures are not strictly necessary to demonstrate attainment with the PM2.5 NAAQS.'' See Sierra Club v. EPA, Nos. 12-3169, 12-3182, 12-3420 (6th Cir. July 14, 2015).
---------------------------------------------------------------------------

What are EPA's proposed actions?
EPA is bound by the Sixth Circuit's decision in Sierra Club v. EPA within the Court's jurisdiction unless it is overturned.\3\ Although EPA continues to believe that Subpart 1 RACM is not an applicable requirement under section 107(d)(3)(E) for an area that has already attained the 1997 Annual PM2.5 NAAQS, EPA is proposing two separate but related actions regarding the Tennessee portion of the Chattanooga

TN-GA-AL Area in response to the Court's decision.4 5
---------------------------------------------------------------------------
\3\ The states of Kentucky, Michigan, Ohio, and Tennessee are located within the Sixth Circuit's jurisdiction.
\4\ Pursuant to 40 CFR 56.5(b), the EPA Region 4 Regional Administrator signed a memorandum on July 20, 2015, seeking concurrence from the Director of EPA's Air Quality Policy Division (AQPD) in the Office of Air Quality Planning and Standards to act inconsistent with EPA's interpretation of CAA sections 107(d)(3)(E) and 172(c)(1) when taking action on pending and future redesignation requests in Kentucky and Tennessee because the Region is bound by the Sixth Circuit's decision in Sierra Club v. EPA. The AQPD Director issued her concurrence on July 22, 2015. The July 20, 2015, memorandum with AQPD concurrence is located in the docket for today's proposed actions.
\5\ On September 3, 2015, the Sixth Circuit denied the petitions for rehearing en banc of this portion of its opinion that were filed by EPA, the state of Ohio, and industry groups from Ohio. Sierra Club v. EPA, Nos. 12-3169, 12-3182, 12-3420, Doc. 136-1 (6th Cir. Sept. 3, 2015).
---------------------------------------------------------------------------
First, EPA is proposing to approve the portion of the State's October 15, 2009, attainment plan SIP revision that addresses RACM under Subpart 1 for the Tennessee portion of the Area. Second, EPA is supplementing the Agency's proposed approval of Tennessee's November 13, 2014, redesignation request for the Area by proposing that approval of the RACM portion of the aforementioned SIP revision satisfies the Subpart 1 RACM requirement in accordance with section 107(d)(3)(E) of the CAA. More detail on EPA's rationale for these proposed actions is provided below.
-
What is EPA's analysis of the state's RACM submittal?
-
Subpart 1 RACM Requirements
Subpart 1 requires that each attainment plan ``provide for the implementation of all reasonably available control measures as expeditiously as practicable (including such reductions in emissions from the existing sources in the area as may be obtained through the adoption, at a minimum, of reasonably available control technology), and shall provide for attainment of the national primary ambient air quality standards.'' See CAA section 172(c)(1). EPA interprets RACM, including RACT, under section 172(c)(1) as measures that are both reasonably available and necessary to demonstrate attainment as expeditiously as practicable in the nonattainment area. See 40 CFR 51.1010(a).\6\ A state must adopt, as RACM, measures that are reasonably available considering technical and economic feasibility if, considered collectively, they would advance the attainment date by one year or more. See 40 CFR 51.1010(b).
---------------------------------------------------------------------------
\6\ Subpart 1 RACM requirements at 40 CFR 51.1010 were not at issue in the D.C. Circuit's remand of the PM2.5 implementation rule in the January 2013 Natural Resources Defense Council v. EPA decision and are therefore not subject to the Court's remand. Cf. NRDC v. EPA, 571 F.3d 1245, 1252-53 (D.C. Cir. 2009) (upholding a substantially similar interpretation of Subpart 1 RACM in the context of ozone implementation regulations).
---------------------------------------------------------------------------
The PM2.5 Implementation Rule requires that the Subpart 1 RACM portion of the attainment plan SIP revision include the list of potential measures that a state considered and information sufficient to show that the state met all requirements for the determination of what constitutes RACM in a specific nonattainment area. See 40 CFR 51.1010(a). Any measures that are necessary to meet these requirements which are not already either federally promulgated, part of the state's implementation plan, or otherwise creditable in SIPs must be submitted in enforceable form as part of a state's attainment plan SIP revision for the area. As discussed above, an attainment determination suspends the requirement for a PM2.5 nonattainment area to submit an attainment plan SIP revision so long as the area continues to attain the PM2.5 NAAQS. See 40 CFR 51.1004(c).
-
Proposed Action on RACM Based Upon Attainment of the NAAQS
EPA is proposing to approve the portion of Tennessee's October 15, 2009, attainment plan SIP revision that addresses Subpart 1 RACM for the State's portion of the Area on the basis that the Area has attained the 1997 Annual PM2.5 NAAQS and, therefore, no emission reduction measures are necessary to satisfy Subpart 1 RACM. As noted above, EPA has determined that the Area has attaining data for the 1997 Annual PM2.5 NAAQS and met the standard by the April 5, 2010, attainment date. See 77 FR 31239. Because the Area has attained the standard, there are no emissions controls that could advance the attainment date; thus, no emissions controls are necessary to satisfy Subpart 1 RACM pursuant to 40 CFR 51.1010 (defining RACM as the level of control necessary to advance the attainment date by one year or more).
-
Proposed Action on RACM Based Upon the State's Control Evaluation
Additionally, the portion of Tennessee's October 15, 2009, attainment plan SIP revision that addresses Subpart 1 RACM for the State's portion of the Area is approvable on the basis that the SIP revision demonstrates that no additional reasonably available controls would have advanced the attainment date projected therein.
Through participation in the regional planning efforts of the Visibility Improvement States and Tribal Association of the Southeast (VISTAS) and the Association for Southeastern Integrated Planning (ASIP), Tennessee determined that existing measures and measures planned for implementation by 2009 would result in the Chattanooga TN-
GA-AL Area attaining the 1997 PM2.5 NAAQS by the end of 2009. Air quality modeling conducted by ASIP indicated that the Area would attain the annual NAAQS in 2009 based upon projected emissions reductions from sources within the Area after 2002 (the base year of the nonattainment emissions inventory). As discussed in Chapter 2.0 of the October 15, 2009, SIP revision, the State, in consultation with VISTAS and ASIP, considered the following existing federally enforceable measures in projecting the emissions inventory used for the 2009 modeling: Tier 2 vehicle standards; heavy-duty gasoline and diesel highway vehicle standards; large nonroad diesel engine standards; nonroad spark-ignition engines and recreational engines standards; NOX SIP call; and the Clean Air Interstate Rule.
In Tennessee's RACM analysis, which appears in chapter 4.0 of the October 15, 2009, SIP revision, the State discusses its evaluation of sources of PM2.5 and its precursors within the Tennessee portion of the Area and its determination that these sources were meeting Subpart 1 RACM levels of emissions control. As discussed above, a State must show that all Subpart 1 RACM (including RACT for stationary sources) necessary to demonstrate attainment as expeditiously as practicable have been adopted and must consider the cumulative impact of implementing available measures to determine whether a particular emission reduction measure or set of measures is required to be adopted as RACM. Potential measures that are reasonably available considering technical and economic feasibility must be adopted as RACM if, considered collectively, they would advance the attainment date by one year or more. Because the attainment demonstration in Tennessee's attainment plan SIP revision showed attainment of the 1997 PM2.5 NAAQS in the Chattanooga TN-GA-
AL Area by the end of 2009, only measures that would advance the attainment date to the end of 2008 would be considered as Subpart 1 RACM.\7\
---------------------------------------------------------------------------
\7\ As noted in the preamble to the PM2.5 Implementation Rule, if a ``State could not achieve significant emissions reductions by the beginning of 2008 due to time needed to implement reasonable measures or other factors, then it could be concluded that reasonably available local measures would not advance the attainment date.'' See 72 FR 20617.
---------------------------------------------------------------------------
Page 56421
Based on the emissions inventory and other information, the State identified the categories of sources that should be evaluated for controls. These categories include permitted stationary sources; gasoline dispensing facilities; on-road mobile sources; non-road and stationary internal combustion engines; open burning; and home heating with wood.
With regard to permitted stationary sources, Tennessee noted that conservative sensitivity modeling, conducted by the Georgia Institute of Technology, showed that completely eliminating emissions of PM2.5, nitrogen oxides, and sulfur dioxide from non-utility point sources in the Tennessee portion of the Area would result in only small reductions in PM2.5 concentrations (0.06 mug/m\3\ to 0.25 mug/m\3\). Nevertheless, Tennessee performed a detailed analysis of each major source operating in the State's portion of the Area and determined that RACT levels of emission control were already in place.\8\ This analysis, and the results of sensitivity modeling, indicated that no additional reductions were available from local permitted stationary sources that would result in attainment in 2008 rather than 2009. For gasoline dispensing facilities, Tennessee deemed the use of Stage 1 vapor recovery to be the RACT level of emissions control. Tennessee stated that the existing federally-approved inspection and maintenance program constitutes RACM for on-road mobile sources and that non-road mobile sources and stationary internal combustion engines are regulated by Federal rules. Regarding open burning, Chattanooga's federally-approved local implementation plan requires open burning permits, bans open burning from May 1 through September 30, and prohibits the burning of brush cleared for road building and trash in the Tennessee portion of the Area. The State also determined that only 712 households (0.6 percent of the total households in the Tennessee portion of the Area) were heating primarily with wood and that accelerated replacement of older wood burning stoves would not advance the attainment date given the ``small portion of households using wood hearing, the mild local climate, and the normal purchases of Subpart AAA compliant wood burning stoves in the nonattainment area.''
---------------------------------------------------------------------------
\8\ See Appendix 12 of the SIP submittal for a detailed discussion of the State's analysis.
---------------------------------------------------------------------------
Through this evaluation, Tennessee determined that, for each category of potential measures, there were either no additional emission reductions that could be achieved or no emission reduction measures that could be practicably implemented in time to advance attainment to the end of 2008. EPA has reviewed the RACM portion of Tennessee's October 15, 2009, attainment plan SIP revision and agrees with the State's conclusion that no additional emissions reductions were available from local sources that would have advanced the projected 2009 attainment date.

Why is EPA supplementing its proposed redesignation of the area?
EPA's March 11, 2015, proposal to approve Tennessee's redesignation request for the Tennessee portion of the Area was based, in part, on the Agency's longstanding interpretation that Subpart 1 RACM need not be approved into a SIP before redesignation to attainment if the subject area is attaining the NAAQS. See 80 FR 16331. Although EPA disagrees with the portion of the Sixth Circuit's opinion in Sierra Club v. EPA that is inconsistent with this interpretation, the Agency is bound by this decision within the Court's jurisdiction unless it is overturned and must first approve Subpart 1 RACM into Tennessee's SIP before it can redesignate the Chattanooga TN-GA-AL Area to attainment. Therefore, EPA is supplementing its redesignation proposal to now rely on approval of the RACM portion of the State's October 15, 2009, attainment plan SIP revision.
-
Proposed Actions
EPA has reviewed the RACM portion of Tennessee's October 15, 2009, attainment plan SIP revision and proposes to approve it on the basis that it is consistent with the CAA, the CAA's implementing regulations, and EPA guidance for attainment demonstration submittals. EPA is also supplementing its March 27, 2015, proposed approval of the State's November 13, 2014, redesignation request for the Tennessee portion of the Chattanooga TN-GA-AL Area by proposing that approval of the RACM portion of the aforementioned SIP revision satisfies the Subpart 1 RACM requirement in accordance with section 107(d)(3)(E) of the CAA. Today's proposed actions are focused solely on addressing the Sixth Circuit's decision in Sierra Club v. EPA and do not reopen any other aspect of the March 27, 2015, proposal for comment.

Statutory and Executive Order Reviews
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable Federal regulations. See 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this action:
Is not a significant regulatory action subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
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);
does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and
does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.
