Background
On October 30, 2017, the Pennsylvania Department of Environmental Protection (PADEP) submitted on behalf of the Commonwealth of Pennsylvania a formal revision, requesting EPA's approval for the SIP of its NNSR Certification for the 2008 Ozone Standard and its existing Emission Statement Program. EPA is only acting on the NNSR Certification portion of the SIP revision in this action. EPA previously finalized a rulemaking action for the existing Emission Statement Program. See 83 FR 26221 (June 6, 2018). This SIP revision is in response to EPA's final 2008 8-hour ozone NAAQS Findings of Failure to Submit for NNSR requirements. See 82 FR 9158 (February 3, 2017). Specifically, Pennsylvania is certifying that its existing NNSR program, covering the Allentown-Bethlehem-Easton, PA Nonattainment Area (which includes Carbon, Lehigh, and Northampton Counties), the Lancaster, PA Nonattainment Area (which includes Lancaster County) the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE Nonattainment Area (which includes Bucks, Chester, Delaware, Montgomery, and Philadelphia Counties), Pittsburgh-Beaver Valley, PA Nonattainment Area (which includes Allegheny, Beaver, Butler, Fayette, Washington, and Westmoreland Counties) and the Reading, PA Nonattainment Area (which includes Berks County) for the 2008 8-hour ozone NAAQS, is at least as stringent as the requirements at 40 CFR 51.165, as amended by the final rule titled ``Implementation of the 2008 National Ambient Air Quality Standards for Ozone: State Implementation Plan Requirements'' (SIP Requirements Rule), for ozone and its precursors.1 2 See 80 FR 12264 (March 6, 2015).
---------------------------------------------------------------------------
\1\ The SIP Requirements Rule addresses a range of nonattainment area SIP requirements for the 2008 8-hour ozone NAAQS, including requirements pertaining to attainment demonstrations, reasonable further progress (RFP), reasonably available control technology, reasonably available control measures, major new source review, emission inventories, and the timing of SIP submissions and of compliance with emission control measures in the SIP. The rule also revokes the 1997 ozone NAAQS and establishes anti-backsliding requirements.
\2\ On February 16, 2018, the United States Court of Appeals for the District of Columbia Circuit (D.C. Cir. Court or Court) issued an opinion on the EPA's SIP Requirements Rule. South Coast Air Quality Mgmt. Dist. v. EPA, 882 F.3d 1138, 2018 U.S. App. LEXIS 3636 (D.C. Cir. Feb. 16, 2018). The D.C. Cir. Court found certain provisions from the SIP Requirements Rule, including certain provisions relating to anti-backsliding, to be inconsistent with the statute or unreasonable and vacated those provisions. Id. The Court found other parts of the SIP Requirements Rule unrelated to anti-
backsliding and this action reasonable and denied the petition for appeal on those provisions. Id.

2008 8-Hour Ozone NAAQS
On March 12, 2008, EPA promulgated a revised 8-hour ozone NAAQS of 0.075 parts per million (ppm). See 73 FR 16436 (March 27, 2008). Under EPA's regulations at 40 CFR 50.15, the 2008 8-hour ozone NAAQS is attained when the three-year average of the annual fourth-highest daily maximum 8-hour average ambient air quality ozone concentrations is less than or equal to 0.075 ppm.
Upon promulgation of a new or revised NAAQS, the CAA requires EPA to designate as nonattainment any area that is violating the NAAQS based on the three most recent years of ambient air quality data at the conclusion of the designation process. The Allentown-Bethlehem-Easton, PA Nonattainment Area, the Lancaster, PA Nonattainment Area, the Pittsburgh-Beaver Valley, PA Nonattainment Area, and the Reading, PA Nonattainment Area were classified as marginal nonattainment areas for the 2008 8-hour ozone NAAQS on May 21, 2012 (effective July 20, 2012) using 2009-2011 ambient air quality data. See 77 FR 30088. The Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE Nonattainment Area was classified as a marginal nonattainment area for the 2008 8-hour ozone NAAQS on May 21, 2012 (effective July 20, 2012) using 2008-2010 ambient air quality data. See 77 FR 30088. On March 6, 2015, EPA issued the final SIP Requirements Rule, which establishes the requirements that state, tribal, and local air quality management agencies must meet as they develop implementation plans for areas where air quality exceeds the 2008 8-hour ozone NAAQS. See 80 FR 12264. Areas that were designated as marginal ozone nonattainment areas were required to attain the 2008 8-hour ozone NAAQS no later than July 20, 2015, based on 2012-2014 monitoring data. See 40 CFR 51.1103.
The Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE and the Pittsburgh-Beaver Valley, PA Nonattainment Areas did not attain the 2008 8-hour ozone NAAQS by July 20, 2015; however, these areas did meet the CAA section 181(a)(5) criteria, as interpreted in 40 CFR 51.1107, for a one-year attainment date extension. See 81 FR 26697 (May 4, 2016). Therefore, on April 11, 2016, the EPA Administrator signed a final rule extending the Philadelphia-Wilmington-Atlantic City, PA-NJ-
MD-DE and the Pittsburgh-Beaver Valley, PA Nonattainment Area 8-hour ozone NAAQS attainment dates from July 20, 2015 to July 20, 2016. Id.\3\ Based on
Page 62776
initial nonattainment designations for the 2008 8-hour ozone standard, as well as the March 6, 2015 final SIP Requirements Rule, Pennsylvania was required to develop a SIP revision addressing certain CAA requirements for the Allentown-Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD-DE, the Pittsburgh-
Beaver Valley, PA, and the Reading, PA Nonattainment Areas, and submit to EPA a NNSR Certification SIP or SIP revision no later than 36 months after the effective date of area designations for the 2008 8-hour ozone NAAQS (i.e., July 20, 2015).\4\ See 80 FR 12264 (March 6, 2015). EPA is proposing to approve Pennsylvania's October 30, 2017 NNSR Certification SIP revision. EPA's analysis of how this SIP revision addresses the NNSR requirements for the 2008 8-hour ozone NAAQS is provided in Section II below.
---------------------------------------------------------------------------
\3\ EPA proposed approval of a Determination of Attainment (DOA) for the 2008 8-hour ozone NAAQS for the Philadelphia-Wilmington-
Atlantic City, PA-NJ-MD-DE Area and the Pittsburgh-Beaver Valley, PA Area on April 18, 2017, and August 25, 2016, respectively. These proposed actions were based on complete, certified, and quality assured ambient air quality monitoring data for the 2013-2015 monitoring period. See 82 FR 18268 (April 18, 2017) and 81 FR 58435 (August 25, 2016). It should be noted that a DOA does not alleviate the need for Pennsylvania to certify that their existing SIP approved NNSR program is as stringent as the requirements at 40 CFR 51.165, as NNSR applies in nonattainment areas until an area has been redesignated to attainment. EPA issued final rulemaking actions on both of these DOAs. See 82 FR 50814 (November 2, 2017) (Philadelphia Area) and 81 FR 87819 (December 6, 2016) (Pittsburgh Area).
\4\ Neither Pennsylvania's obligation to submit the NNSR Certification SIP nor the requirements governing that submission were affected by the D.C. Circuit's February 16, 2018 decision on portions of the SIP Requirements Rule in South Coast Air Quality Mgmt. Dist. v. EPA.

2017 Findings of Failure To Submit SIP for the 2008 8-Hour Ozone NAAQS
Areas designated nonattainment for the ozone NAAQS are subject to the general nonattainment area planning requirements of CAA section 172 and also to the ozone-specific planning requirements of CAA section 182.\5\ States in the ozone transport region (OTR), such as Pennsylvania, are additionally subject to the requirements outlined in CAA section 184.
---------------------------------------------------------------------------
\5\ Ozone nonattainment areas are classified based on the severity of their ozone levels (as determined based on the area's ``design value,'' which represents air quality in the area for the most recent three years). The possible classifications for ozone nonattainment areas are Marginal, Moderate, Serious, Severe, and Extreme. See CAA section 181(a)(1).
---------------------------------------------------------------------------
Ozone nonattainment areas in the lower classification levels have fewer and/or less stringent mandatory air quality planning and control requirements than those in higher classifications. For marginal areas, such as the Allentown-Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD, DE, the Pittsburgh-
Beaver Valley, PA, and the Reading, PA Areas, a state is required to submit a baseline emissions inventory, adopt a SIP requiring emissions statements from stationary sources, and implement a NNSR program for the relevant ozone standard. See CAA section 182(a). For each higher ozone nonattainment classification, a state needs to comply with all lower area classification requirements, plus additional emissions controls and more expansive NNSR offset requirements.
The CAA sets out specific requirements for states in the OTR.\6\ Upon promulgation of the 2008 8-hour ozone NAAQS, states in the OTR were required to submit a SIP revision addressing reasonably available control technology (RACT). See 40 CFR 51.1116. This requirement is the only recurring obligation for an OTR state upon revision of a NAAQS, unless that state also contains some portion of a nonattainment area for the revised NAAQS.\7\ In that case, the nonattainment requirements described previously also apply to those portions of that state.
---------------------------------------------------------------------------
\6\ CAA section 184 details specific requirements for a group of states (and the District of Columbia) that make up the OTR. States in the OTR are required to submit RACT SIP revisions and mandate a certain level of emissions control for the pollutants that form ozone, even if the areas in the state meet the ozone standards.
\7\ NNSR requirements continue to apply in the OTR. See CAA section 184(b).
---------------------------------------------------------------------------
In the March 6, 2015 SIP Requirements Rule, EPA detailed the requirements applicable to ozone nonattainment areas, as well as requirements that apply in the OTR, and provided specific deadlines for SIP submittals. See 80 FR 12264.
On February 3, 2017, EPA found that 15 states and the District of Columbia failed to submit SIP revisions in a timely manner to satisfy certain requirements for the 2008 8-hour ozone NAAQS that apply to nonattainment areas and/or states in the OTR. See 82 FR 9158. As explained in that rulemaking action, consistent with the CAA and EPA regulations, these Findings of Failure to Submit established certain deadlines for the imposition of sanctions, if a state does not submit a timely SIP revision addressing the requirements for which the finding is being made, and for the EPA to promulgate a Federal implementation plan (FIP) to address any outstanding SIP requirements.
EPA found, inter alia, that the Commonwealth of Pennsylvania failed to submit SIP revisions in a timely matter to satisfy NNSR requirements for its marginal nonattainment areas, specifically the Allentown-
Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-
Atlantic City, PA-NJ-MD, DE, the Pittsburgh-Beaver Valley, PA, and the Reading, PA Areas.\8\ Pennsylvania submitted its October 30, 2017 SIP revision to address the specific NNSR requirements for the 2008 8-hour ozone NAAQS, located in 40 CFR 51.160-165, as well as its obligations under EPA's February 3, 2017 Findings of Failure to Submit. EPA's analysis of how this SIP revision addresses the NNSR requirements for the 2008 8-hour ozone NAAQS and the Findings of Failure to Submit is provided in Section II below.
---------------------------------------------------------------------------
\8\ The EPA found that the Commonwealth of Pennsylvania also failed to submit a SIP revision for the Control Techniques Guidelines (CTG) for the volatile organic compound RACT (for all 44 CTGs). This SIP requirement will be addressed in a separate rulemaking action and will not be discussed here. See 82 FR 9158 (February 3, 2017).

Summary of SIP Revision and EPA Analysis
This rulemaking action is specific to Pennsylvania's NNSR requirements. NNSR is a preconstruction review permit program that applies to new major stationary sources or major modifications at existing sources located in a nonattainment area.\9\ The specific NNSR requirements for the 2008 8-hour ozone NAAQS are located in 40 CFR 51.160-165. As set forth in the SIP Requirements Rule, for each nonattainment area, a NNSR plan or plan revision was due no later than 36 months after the July 20, 2012 effective date of area designations for the 2008 8-hour ozone standard (i.e., July 20, 2015).\10\
---------------------------------------------------------------------------
\9\ See CAA sections 172(c)(5), 173 and 182.
\10\ With respect to states with nonattainment areas subject to a Findings of Failure to Submit NNSR SIP revisions, such revisions would no longer be required if the area were redesignated to attainment. The CAA's prevention of significant deterioration (PSD) program requirements apply in lieu of NNSR after an area is redesignated to attainment. For areas outside the OTR, NNSR requirements do not apply in areas designated as attainment.
---------------------------------------------------------------------------
The minimum SIP requirements for NNSR permitting programs for the 2008 8-hour ozone NAAQS are located in 40 CFR 51.165. See 40 CFR 51.1114. These NNSR program requirements include those promulgated in the ``Phase 2 Rule'' implementing the 1997 8-hour ozone NAAQS (75 FR 71018 (November 29, 2005)) and the SIP Requirements Rule implementing the 2008 8-hour ozone NAAQS. Under the Phase 2 Rule, the SIP for each ozone nonattainment area must contain NNSR provisions that: Set major source thresholds for oxides of nitrogen (NOX) and volatile organic compounds (VOC) pursuant to 40 CFR 51.165(a)(1)(iv)(A)(1)(i)-
(iv) and (2); classify physical changes as a major source if the change would constitute a major source by itself pursuant to 40 CFR 51.165(a)(1)(iv)(A)(3); consider any significant net emissions increase of NOX as a significant net emissions increase for ozone pursuant to 40 CFR 51.165(a)(1)(v)(E); consider certain increases of VOC emissions in extreme ozone nonattainment areas as a significant net emissions increase and a
Page 62777
major modification for ozone pursuant to 40 CFR 51.165(a)(1)(v)(F); set significant emissions rates for VOC and NOX as ozone precursors pursuant to 40 CFR 51.165(a)(1)(x)(A)-(C) and (E); contain provisions for emissions reductions credits pursuant to 40 CFR 51.165(a)(3)(ii)(C)(1)-(2); provide that the requirements applicable to VOC also apply to NOX pursuant to 40 CFR 51.165(a)(8); and set offset ratios for VOC and NOX pursuant to 40 CFR 51.165(a)(9)(i)-(iii) (renumbered as (a)(9)(ii)-(iv) under the SIP Requirements Rule for the 2008 8-hour ozone NAAQS). Under the SIP Requirements Rule for the 2008 8-hour ozone NAAQS, the SIP for each ozone nonattainment area designated nonattainment for the 2008 8-hour ozone NAAQS and designated nonattainment for the 1997 ozone NAAQS on April 6, 2015, must also contain NNSR provisions that include the anti-
backsliding requirements at 40 CFR 51.1105. See 40 CFR 51.165(a)(12).
Pennsylvania's SIP approved NNSR program, established in the Pennsylvania Code of Regulations (Pa. Code) Rule 25 Pa. Code Chapter 127--Construction, Modification, Reactivation, and Operation of Sources, applies to the construction and modification of major stationary sources in nonattainment areas. In its October 30, 2017 SIP revision, Pennsylvania certifies that the version of 25 Pa. Code Chapter 127 in the SIP is at least as stringent as the Federal NNSR requirements for the Allentown-Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD, DE, the Pittsburgh-Beaver Valley, PA, and the Reading, PA Nonattainment Areas. EPA last approved revisions to Pennsylvania's major NNSR SIP on May 14, 2012. In that action, EPA approved revisions to Pennsylvania's SIP which made PADEP's NNSR program consistent with Federal requirements. See 77 FR 28261.
EPA notes that 25 Pa. Code Section 127.207(5) nor Pennsylvania's approved SIP contain a regulatory provision pertaining to establishing emissions reductions credits (ERC), as specified in 40 CFR 51.165(a)(3)(ii)(C)(2)(i) and 40 CFR 51.165(a)(3)(ii)(C)(2)(ii). However, even if Pennsylvania's regulations do not offer this emissions reductions credit option, their approved SIP is still adequate to meet the standard ERC requirements found in 40 CFR 51.165(a)(3)(ii)(C)(1), where emissions reductions must be surplus, permanent, quantifiable, and Federally enforceable, for example. Pennsylvania has the appropriate ERC requirements approved in their regulations and their SIP, which enables them to implement the program appropriately and in accordance with Federal requirements.
Given the D.C. Cir. Court's recent ruling in South Coast Air Quality Mgmt. Dist. v. EPA vacating the anti-backsliding provisions of the SIP Requirements Rule, Pennsylvania remains required to comply with the anti-backsliding provisions found in 40 CFR 51.165(a)(12). In Pennsylvania, neither 25 Pa. Code Chapter 127 or the Pennsylvania SIP contain the anti-backsliding provisions found in 40 CFR 51.165(a)(12), which applied to NNSR requirements for the 1997 ozone NAAQS. However, EPA finds that 25 Pa. Code and Pennsylvania's SIP presently include appropriate thresholds for major stationary sources and emissions offset ratios for the worst air quality designations these nonattainment areas have been designated. For example, in 25 Pa. Code Section 121.1, a source is considered a ``major NOX emitting facility'' if it emits 25 tons per year of NOX in Bucks, Chester, Delaware, Montgomery or Philadelphia County (the Philadelphia-
Wilmington-Atlantic City, PA-NJ-MD-DE Nonattainment Area). This emissions threshold is equivalent to an area that was designated as severe nonattainment for the ozone NAAQS and is therefore more stringent. In addition, the entire state of Pennsylvania is located in the OTR and any source in the OTR is considered major for NOX and VOC if it emits or has the potential to emit at least 100 tons per year or 50 tons per year, respectively. This requirement can be found in 25 Pa. Code Section 127.201(c), as well as Pennsylvania's approved SIP and is equivalent to the higher moderate nonattainment area classification. Additionally, emissions offset ratios for sources located in Pennsylvania are more stringent than the requirements of 40 CFR 51.165(a)(9)(i). 25 Pa. Code Section 127.210 and the approved Pennsylvania SIP require sources in a marginal nonattainment area to offset their NOX and VOC emissions at a ratio of 1.15 to 1 versus the Federal NNSR requirement for a source located in a marginal nonattainment area to offset NOX and VOC at a less stringent ratio of 1.1 to 1. See 40 CFR 51.165(a)(9)(i)(A). Therefore, EPA finds that Pennsylvania's regulations and approved SIP are more stringent than EPA's NNSR anti-
backsliding requirements and their program is adequate to implement NNSR for the 2008 ozone NAAQS.
The version of 25 Pa. Code Chapter 127 that is contained in the current SIP has not changed since the 2012 rulemaking where EPA last approved Pennsylvania's NNSR provisions, with respect to ozone and its precursors.\11\ This version of the rule covers the Allentown-
Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-
Atlantic City, PA-NJ-MD, DE, the Pittsburgh-Beaver Valley, PA, and the Reading, PA Nonattainment Areas and remains adequate to meet all applicable NNSR requirements for the 2008 8-hour ozone NAAQS found in 40 CFR 51.165, the Phase 2 Rule and the SIP Requirements Rule.
---------------------------------------------------------------------------
\11\ Subsequently, EPA did approve an update to Pennsylvania's SIP incorporating preconstruction permitting requirements for fine particulate matter (PM2.5) into their NNSR regulations on July 13, 2012. See 77 FR 41276.
---------------------------------------------------------------------------

Proposed Action
EPA is proposing to approve Pennsylvania's October 30, 2017 SIP revision addressing the NNSR requirements for the 2008 ozone NAAQS for the Allentown-Bethlehem-Easton, PA, the Lancaster, PA, the Philadelphia-Wilmington-Atlantic City, PA-NJ-MD, DE, the Pittsburgh-
Beaver Valley, PA, and the Reading, PA Nonattainment Areas. EPA has concluded that the Commonwealth's submission fulfills the 40 CFR 51.1114 revision requirement, meets the requirements of CAA sections 110 and 172 and the minimum SIP requirements of 40 CFR 51.165, as well as its obligations under EPA's February 3, 2017 Findings of Failure to Submit. See 82 FR 9158. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action.

Statutory and Executive Order Reviews
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 proposed 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);
Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory
Page 62778
action because SIP approvals are exempted under Executive Order 12866.
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 (Public Law 104-4);
Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 7, 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 proposed rule, approving Pennsylvania's 2008 8-
hour ozone NAAQS Certification SIP revision for NNSR 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.
