Environmental Protection Agency (EPA).
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision by the Commonwealth of Pennsylvania, on behalf of the Allegheny County Health Department (ACHD), on May 23, 2019. The revision pertains to ACHD's amendments of the ACHD Rules and Regulations, Article XXI (Air Pollution Control) to implement Federal nonattainment new source review (NNSR) provisions for the 2012 annual fine particulate matter (PM2.5) national ambient air quality standard (NAAQS). EPA is approving these revisions to the Allegheny County portion of the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).
This final rule is effective on July 15, 2020.
EPA has established a docket for this action under Docket ID Number EPA-R03-OAR-2019-0469. All documents in the docket are listed on the https://www.regulations.gov website.

Start Supplemental Information
On March 5, 2020 (85 FR 12882), EPA published a notice of proposed rulemaking (NPRM) for Allegheny County, Pennsylvania. In the NPRM, EPA proposed approval of amendments to ACHD Rules and Regulations, Article XXI (Air Pollution Control), sections 2102.06 (Major Sources Locating in or Impacting a Nonattainment Area), and 2101.20 (Definitions), herein referred to as Revision 90A. Specifically, Revision 90A establishes that emissions of volatile organic compounds (VOC) and ammonia are precursors to PM2.5 for new and modified major sources emitting PM2.5 in Allegheny County, Pennsylvania; establishes a significant impact level for PM2.5; proposes emission offset ratios for emissions of VOC and ammonia as PM2.5 precursors; and amends relevant definitions. The formal SIP revision was submitted by the Commonwealth of Pennsylvania, on behalf of ACHD, on May 23, 2019.
EPA has revised the NAAQS for PM2.5 on multiple occasions, most recently in 2012. On December 14, 2012, the annual primary standard for PM2.5 was lowered from 15 micrograms per meter cubed (μg/m3) to 12 μg/m3. See 78 FR 3087 (January 15, 2013). The existing 24-hour standards (primary and secondary) were retained at 35 μg/m3, as was the annual secondary standard of 15 μg/m3. Upon promulgation of the 2012 PM2.5 NAAQS, EPA formally classified all of Allegheny County, Pennsylvania as moderate nonattainment for the 2012 annual PM2.5 standard. See 80 FR 2206 (January 15, 2015).
For areas designated as nonattainment for one or more NAAQS, the SIP must include preconstruction permit requirements for new or modified major stationary sources of such nonattainment pollutant(s), commonly referred to as “Nonattainment New Source Review.” See CAA section 172(c)(5).
ACHD's Revision 90A revises NNSR permit requirements for major sources of PM2.5. Specifically, ACHD's Article XXI has been amended to implement additional provisions pertaining to PM2.5 precursors, as promulgated in EPA's rule entitled Fine Particulate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements (2016 Implementation Rule). See 81 FR 58010 (August 24, 2016).
As required by EPA's 2016 Implementation Rule, which implements the D.C. Circuit Court's January 2013 decision in NRDC v. EPA,
areas classified as nonattainment for any PM2.5 NAAQS are required to comply with the provisions of CAA subpart 4 section 189(e) that require the control of major sources of PM10 precursors (and hence under the court decision, PM2.5 precursors) “except where the Administrator determines that such sources do not contribute significantly to PM10 levels which exceed the standard in the area.” 
With respect the NNSR permitting requirements, the 2016 Implementation Rule therefore Start Printed Page 36162amended the definitions in 40 CFR 51.165(a)(1) for (1) “regulated NSR pollutant” with regard to PM2.5 precursors; (2) “major stationary source” with regard to major sources locating in PM2.5 nonattainment areas classified as moderate and serious; and (3) “significant” with regard to emissions of PM2.5 precursors.
II. Summary of SIP Revision and EPA Analysis
A. Summary of SIP Revision
Article XXI addresses NNSR permit requirements for major sources of PM2.5. ACHD's Revision 90A has been amended to implement additional provisions pertaining to precursors, as promulgated in EPA's final 2016 Implementation Rule.
B. EPA's Proposed Action
At proposal, EPA evaluated the revised portions of Article XXI to determine if the revisions meet current applicable requirements for a PM2.5 NNSR permit program, as revised by EPA's 2016 Implementation Rule. Section 2102.06—(1) contains revisions to clarify that Article XXI applies to major polluting facilities that will emit PM2.5 or its precursors in areas designated as nonattainment for PM2.5; (2) the definition of “major facility” has been updated to include a 70 tons per year (tpy) emissions threshold for PM2.5 and all precursors to PM2.5; (3) the definition of “regulated NSR pollutant” has been updated to include sulfur dioxide (SO2), VOC, and ammonia as PM2.5 precursors in all PM2.5 nonattainment areas; (4) revisions were made to the definition of “significant” to include emission rates for PM2.5 at 10 tpy and emission rates for PM2.5 precursors as follows: 40 tpy of SO2, 40 tpy of VOC, 40 tpy of ammonia, and 40 tpy of nitrogen oxides (NOX); and (5) revisions were made to clarify that under Article XXI, “significance level(s)” shall mean “significant air quality impact” as defined under Article XXI. EPA proposed to find these revisions approvable and consistent applicable requirements for a PM2.5 NNSR permit program, as revised by the 2016 Implementation Rule.
Section 2102.06(b)(3)—Emission Offsets, establishes offset ratios for VOC and ammonia at a ratio of 1:1 for flue emissions and fugitive emissions in Allegheny County. EPA also proposed to find the addition of offset ratios to be approvable, as they match what is already in Article XXI for PM2.5 and NOX and SO2. Further, Section 2101.20—Definitions, was amended to add values to the table of “significant air quality impact” levels under 40 CFR 51.165(b)(2) for PM2.5 at 0.2μg/m3 for the annual averaging time and 1.2 μg/m3 for the 24-hour averaging time. As ACHD's annual averaging time is more stringent than what EPA requires in 40 CFR part 51.165(b)(2), EPA therefore proposed to find this more stringent requirement approvable.
Other specific provisions of SIP Revision 90A and the rationale for EPA's proposed action are explained in the NPRM and its associated technical support document (TSD) and will not be restated here.
III. Public Comments and EPA Responses
EPA received two comments on the March 5, 2020 NPRM. See 85 FR 12882. A summary of the comments and EPA's responses are discussed in this section of the preamble. A copy of the comments can be found in the docket for this rulemaking action.
Comment 1: The first comment stated that EPA should disapprove ACHD's SIP submission because “it lacks the rules that other public entities are required to meet.” The comment also suggested that “because the commission operates in a more limited capacity and the rules for the governing body are less rigid, the law can be used to prevent Allegheny County from complying with SIP requirements.” The comment also noted that the commission in 2013 acknowledged that it had found a way to have regulators use the agency's own rules to change a law (during a time period in which SIP went through changes across the nation).” The comment concluded by saying, “the agency never made a recommendation to cancel the vote.”
Response 1: The commenter has not identified any information to support its assertion that EPA should disapprove ACHD's 2012 PM2.5 NNSR SIP submission. In particular, the commenter failed to identify any rules the Allegheny County SIP lacks or how any provisions adopted by ACHD are inconsistent with the applicable regulatory requirements. The Administrative Procedures Act does not require that EPA change its decision based on unsupported “comments consisting of little more than assertions that in the opinions of the commenters the agency got it wrong.,” International Fabricare Institute v. EPA, 972 F.2d 384 (D.C. Cir. 1992). EPA's review of the 2012 PM2.5 NNSR SIP submission, as explained in the NPRM and TSD for this rulemaking action, shows that Allegheny County is meeting the applicable requirements found in EPA's regulations, as revised by the 2016 Implementation Rule, and the CAA. To the extent the commenter is alleging concerns with respect to implementation of the SIP, the commenter again provides insufficient details regarding these issues. For example, the commenter does not identify with any specificity what 2013 action it believes is relevant or what vote was allegedly cancelled. More importantly, concerns regarding implementation are outside the scope of EPA's SIP review, which is focused under section 110(k) on whether the submission meets the applicable requirements of the CAA. See, e.g., Montana Environmental Information Center v. Thomas, 902 F.3d 971, 978-79 (9th Cir. 2018). SIP approval was not arbitrary and capricious where EPA reasonably interpreted submission as facially meeting the applicable requirements despite alleged implementation concerns. Accordingly, the commenter has not identified any basis for EPA to reconsider its approval of Revision 90A into the Allegheny County portion of the Pennsylvania SIP.
Comment 2: The second comment stated that EPA must not approve Revision 90A “because Ammonia (sic) is a harmful precursor that is not regulated by EPA.” The comment further asserted that EPA does not have the “authority under the Clean Air Act of 1990 to regulate Ammonia (sic) since it is not a NAAQS pollutant.” Lastly, the comment suggests that EPA should disregard this rulemaking action and move to make ammonia a criteria pollutant, as it is a “dangerous and extremely harmful pollutant.”
Response 2: EPA agrees with the commenter's assertion that ammonia is a precursor pollutant that contributes to the formation of PM2.5. See NRDC, 706 F.3d at 435, n. 7 (“Ammonia is a precursor to fine particulate matter, making it a precursor to both PM2.5 and PM10.”). However, EPA disagrees with the comment that it does not have the authority to regulate ammonia under the CAA. To the contrary, the D.C. Circuit Court's NRDC decision held that areas classified as nonattainment for any PM2.5 NAAQS are required to comply with the provisions of CAA subpart 4 section 189(e) that require the control of major stationary sources of precursors except where the Administrator determines that such sources do not contribute significantly to levels which exceed the standard in the area. The NNSR permit program for PM2.5 thus presumptively applies to emissions of all precursors, including ammonia, as well as direct PM2.5 emissions from Start Printed Page 36163major sources in Allegheny County.
This indicates that, contrary to the commenter's assertion, the CAA does not limit EPA's authority to only regulating the direct emissions of criteria pollutants for which NAAQS are promulgated. Rather, even though ammonia is not identified under the statute as a criteria pollutant, EPA is not only authorized, but required to regulate ammonia as a PM2.5 precursor under section 189(e).
EPA's review of SIP Revision 90A, as explained in the NPRM and TSD for this rulemaking action, shows that Allegheny County is meeting the applicable requirements found in EPA's 2016 Implementation Rule, which implements the NRDC decision, and the CAA. Therefore, EPA is finalizing its approval of Revision 90A.
IV. Final Action
EPA is approving amendments to ACHD Rules and Regulations, Article XXI (Air Pollution Control), sections 2102.06 (Major Sources Locating in or Impacting a Nonattainment Area), and 2101.20 (Definitions) as a revision to the Allegheny County portion of the Pennsylvania SIP.
V. Incorporation by Reference
In this document, EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, EPA is finalizing the incorporation by reference of ACHD's Article XXI, sections 2102.06, and 2101.20, as described in the amendments to 40 CFR part 52 set forth below. EPA has made, and will continue to make, these materials generally available through https://www.regulations.gov and at the EPA Region III Office (please contact the person identified in the For Further Information Contact section of this preamble for more information). Therefore, these materials have been approved by EPA for inclusion in the SIP, have been incorporated by reference by EPA into that plan, are fully federally enforceable under sections 110 and 113 of the CAA as of the effective date of the final rulemaking of EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.
VI. 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 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 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 (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 August 14, 2020. 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 approving NNSR requirements under the 2012 PM2.5 NAAQS may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
