I. Background II. Summary of State Submittal III. Effects of Recent Court Decisions IV. Final Action V. Statutory and Executive Order Reviews I. Background

The formal SIP revision submittal, prepared by ACHD, was submitted by PADEP on June 17, 2011. The SIP revision included the 1997 annual PM 2.5NAAQS attainment plan for the LibertyClairton Area, a 2002 base year emissions inventory for purposes of meeting the requirement of section 172(c)(3) of the CAA, the transportation conformity motor vehicle emissions budgets (MVEBs), and certain revisions to ACHD regulations. This SIP revision is described in further detail in section II of this rulemaking action.

On November 7, 2011 (76 FR 68699), EPA published a notice of proposed rulemaking (NPR) for the Commonwealth in Pennsylvania. In the NPR, EPA proposed conditional approval of the 1997 annual PM 2.5NAAQS attainment plan for the LibertyClairton Area (the ‘‘attainment plan’’). EPA proposed conditional approval because the attainment plan included air quality modeling that relied on emissions reductions from the Clean Air Interstate Rule (CAIR), which was problematic because at the time CAIR was no longer in place. EPA had promulgated the Cross State Air Pollution Rule (CSAPR) on August 8, 2011 (76 FR 48208) to replace CAIR. As part of this NPR, EPA also proposed to approve the amendments to ACHD regulations included in the June 17, 2011 SIP revision, which added the definition of PM 2.5 and the level of the 1997 annual and 2006 24-hour PM 2.5 NAAQS. No public comments were received on this NPR.

On October 25, 2013 (78 FR 63881),EPA determined that the LibertyClairton Area had attained the 1997 annual PM 2.5 NAAQS, based on qualityassured and certified ambient air quality data for the 2009–2011 and 2010–2012 monitoring periods. This ‘‘clean data determination’’ suspended the requirement for the Liberty-Clairton Area to submit an attainment demonstration, reasonably available control measures (RACM), reasonable further progress (RFP), and contingency measures related to attainment of the 1997 annual PM 2.5 NAAQS, for so long as the Area continues to attain the 1997 annual PM 2.5 NAAQS.

On November 18, 2013, PADEP submitted a letter requesting to


### 55 Federal Register / Vol. 79, No. 1 / Thursday, January 2, 2014 / Rules and Regulations

1 See ‘‘State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,’’ (57 FR 13498, April 16, 1992) (hereafter, General Preamble). EPA notes that it has issued additional guidance for attainment plans for PM 10 in particular, including extra requirements for areas classified as ‘‘serious’’ nonattainment areas under subpart 4. See ‘‘State Implementation Plans for Serious PM 10 Nonattainment Areas, and Attainment Date Waivers for PM 10 Nonattainment Areas Generally; Addendum to the General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990,’’ (59 FR 41998, August 16,1994) (hereafter, Addendum). 2 See 57 FR 13538.

3 See General Preamble, 57 FR 13539. EPA notes, however, that under subpart 4 requirements states may need to submit updated emissions inventories to support later SIP submissions, such as SIP submissions to address the requirements for serious areas under section 189(b)(1), or the requirements for an extension of the serious area attainment date under section 188(e).

4 See 40 CFR 51.1008.

5 See PM 2.5 Implementation Rule, 72 FR 20648. EPA noted that the obligation to address all of the scientific precursors of PM 2.5 was a separate requirement needed to support various regulatory purposes, including the evaluation of whether relying on the rebuttable presumptions for precursors was correct in a given area. withdraw the sections of the June 17, 2011 SIP revision pertaining to the suspended planning requirements for the Liberty-Clairton Area as a result of EPA’s determination of attainment for the Area. Specifically, PADEP requested to withdraw all portions of the June 17, 2011 SIP revision, except for the portions pertaining to the 2002 base year emissions inventory and the revisions to the ACHD regulations, which are discussed in section 2 (Regulatory Changes), section 6 (Emissions Inventory), and appendix F (Stationary Point, Area, Nonroad, and Mobile Emissions Inventories) of the SIP submittal. As a result of PADEP’s November 18, 2013 letter, EPA has no statutory obligation to take further action on the portions of the June 17, 2011 SIP revision that have been withdrawn. Therefore, in this rulemaking action, EPA is only approving of the June 17, 2011 submittal, the 2002 base year emissions inventory and the submitted revisions to ACHD regulations. II. Summary of State Submittal

As discussed in this rulemaking action, the 2002 base year emissions inventory was submitted by PADEP as part of the June 17, 2011 SIP revision. The base year emissions inventory includes emissions estimates that cover the general source categories of point sources, non-road mobile sources, area sources, on-road mobile sources, and biogenic sources. The pollutants that comprise the inventory are nitrogen oxides (NO X ), volatile organic compounds (VOC), PM 2.5 , coarse particles (PM 10 ), ammonia, and sulfur dioxide (SO 2 ). In accordance with 40 CFR 51.1008(b), PADEP selected 2002 as the base year for the emissions inventory. EPA has reviewed the results, procedures and methodologies for the 2002 base year emissions inventory submitted by PADEP and finds them approvable. Further analysis of the emissions inventory development can be found in the June 17, 2011 SIP submittal and in EPA’s October 5, 2011 technical support document (TSD) included as part of the docket for this rulemaking action. See Docket ID Number EPA–R03–2011–0854.

The SIP submittal also included the following amendments to ACHD regulations, which became effective on May 24, 2010: (1) The addition of the 1997 annual PM 2.5 standard level of 15
mg/m 3 , the 2006 24-hour PM 2.5 standard level of 35 mg/m 3 , and the related references to the list of standards in ACHD article XXI section 2101.10 and (2) the addition of the definition of ‘‘PM 2.5 ’’ to ACHD article XXI section 2101.20. These regulatory amendments are described in sections 2 and 6 and appendix F of the June 17, 2011 SIP submittal. EPA’s rationale for approving the described SIP revisions was provided in the NPR and will not be restated here.

III. Effects of Recent Court Decisions

On January 4, 2013, in Natural Resources Defense Council v. EPA, the D.C. Circuit remanded to EPA both the ‘‘Final Clean Air Fine Particle Implementation Rule’’ (72 FR 20586, April 25, 2007) and the ‘‘Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM 2.5 )’’ final rule (73 FR 28321, May 16, 2008) (collectively, ‘‘1997 PM 2.5 Implementation Rule’’ or ‘‘Implementation Rule’’). See 706 F.3d 428 (D.C. Cir. 2013). The Court found that EPA erred in implementing the 1997 annual PM 2.5 NAAQS pursuant solely to the general implementation provisions of subpart 1 of part D of Title I of the CAA (subpart 1), rather than the particulate-matter-specific provisions of subpart 4 of part D of Title I of the CAA (subpart 4). As a result, the D.C. Circuit Court remanded EPA’s Implementation Rule and instructed EPA ‘‘to repromulgate these rules pursuant to subpart 4 consistent with this opinion.’’ Significantly, the Court’s decision remanded the rules to EPA and did not vacate them. In a future rulemaking action, EPA intends to respond to the Court’s remand and to promulgate new implementation regulations for the PM 2.5 NAAQS in accordance with the requirements of subpart 4. In the interim, EPA will proceed to review attainment plans that have already been submitted but are not yet approved where appropriate.

EPA has two longstanding general guidance documents that interpret the 1990 amendments to the CAA, commonly known as the ‘‘General Preamble’’ and the ‘‘Addendum,’’ that make recommendations to states for meeting the statutory requirements for SIPs for nonattainment areas including those of subpart 4. 1 In the General Preamble, EPA discussed the relationship of subpart 1 and subpart 4 SIP requirements, and pointed out that subpart 1 requirements were to an extent ‘‘subsumed by, or integrally related to, the more specific PM 10 requirements.’’ 2 Section 172(c)(3) of the CAA requires that States submit a comprehensive, accurate, and current inventory of actual emissions from all sources in the nonattainment area. In the General Preamble, EPA stated that section 172(c)(3) applies for purposes of subpart 4, which itself contains no additional emissions inventory requirements for purposes of PM 10. 3 Thus, subpart 4 adds no additional emissions inventory requirements.

EPA’s remanded 1997 PM 2.5 Implementation Rule required States to meet emissions inventory requirements, including a statewide emissions inventory of direct PM 2.5 and all PM 2.5 precursors, any additional emissions inventory information needed to support an attainment demonstration and RFP requirements, and a baseline ( i.e. base year) emissions inventory suitable for the SIP planning requirements for the area at issue. 4 As EPA explained in the 1997 PM 2.5 Implementation Rule, in order to ensure that States provide the information necessary for SIP planning, including the need to evaluate which PM 2.5 precursors a state should regulate in a given nonattainment area, the requirements relating to emissions inventories include a requirement that States must provide emissions information for direct PM 2.5, SO 2, NO X , VOCs, and ammonia. 5

EPA believes that the D.C. Circuit Court’s decision in NRDC v. EPA does not affect the emissions inventory requirements for the 1997 annual PM 2.5 NAAQS. The D.C. Circuit Court’s remand of the 1997 PM 2.5 Implementation Rule to EPA with instructions to repromulgate implementation regulations consistent with subpart 4 would not result in additional emissions inventory requirements under subpart 4 because

6 See 76 FR 68699, at 68701.

7 For further details, see the TSD document entitled ‘‘Technical Support Document (TSD) for Liberty-Clairton PM 2.5 Nonattainment Area: State Implementation Plan (SIP) Attainment Demonstration and Base Year Inventory,’’ dated October 5, 2011. The TSD is available in the docket online at www.regulations.gov, Docket Number EPA–R03–OAR–2011–0854. none exist. The D.C. Circuit Court’s comments on addressing PM 2.5 precursors consistent with subpart 4 requirements also would not compel a different approach with respect to emissions inventories from that which EPA required under subpart 1. EPA’s prior approach under subpart 1 already obligated States to include emissions of direct PM 2.5, SO 2, NO X , VOCs, and ammonia in such inventories, and provided no presumptions to exclude precursors from inventories. To the contrary, the emissions inventory requirement includes these precursors to assure adequate information to inform decisions about what pollutants to regulate for purposes of attaining the NAAQS in a given area.

As part of EPA’s November 7, 2011NPR, EPA proposed approval of LibertyClairton Area’s submission with respect to emissions inventory requirements. 6 In that NPR, EPA explained that the Liberty-Clairton Area’s emissions inventory information was consistent with EPA’s guidance and correctly included the emissions of direct PM 2.5, SO 2 , NOx, VOC, and ammonia. 7 Additionally, EPA provided a discussion of the sources of information for emissions from stationary sources, area sources, and mobile sources in the Liberty-Clairton Area and an explanation supporting its proposed finding that the State’s approach was appropriate. No comments were received for this NPR.

Because the emissions inventories,submitted by PADEP as part of LibertyClairton Area’s attainment plan for the 1997 annual PM 2.5 NAAQS, already included emissions of direct PM 2.5, SO 2 , NOx, VOC, and ammonia, EPA concludes that there is no need to reexamine the emissions inventories for the Liberty-Clairton Area. EPA finds that the process used to develop the 2002 base year emissions inventory for the Liberty-Clairton Area is adequate to meet the requirements of CAA section 172(c)(3), the implementing regulations, and EPA guidance for emission inventories with respect the 1997 annual PM 2.5 NAAQS.

IV. Final Action

EPA is approving into the Pennsylvania SIP the 2002 base yearemissions inventory for the LibertyClairton Area for the 1997 annual PM 2.5 NAAQS, which was submitted as part of the June 17, 2011 submittal. EPA is also approving into Pennsylvania’s SIP revisions to article XXI, sections 2101.10 and 2101.20 of ACHD regulations for the addition of the definition of PM 2.5 and the levels of the 1997 annual PM 2.5 and the 2006 24-hour PM 2.5 standards. EPA is not taking action on the remaining portions of the June 17, 2011 submittal, as they were withdrawn by PADEP by a November 18, 2013 letter. V. Statutory and Executive Order Reviews A. General Requirements

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 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 approves 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 Order 12866 (58 FR 51735, October 4, 1993);

• 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).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law. B. Submission to Congress and the Comptroller General

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 action 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). C. Petitions for Judicial Review

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 March 3, 2014. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action 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, which approves the 2002 base year emissions inventory for the Liberty-Clairton Area for the 1997 annual PM 2.5 NAAQS and revisions to ACHD regulations of the PM 2.5 definitions and levels, may not be challenged later in proceedings to enforce its requirements.
