ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2020-0575; FRL-9061-02-R3]


Approval and Promulgation of Air Quality Implementation Plans; 
Pennsylvania; Reasonably Available Control Technology Determinations 
for Case-by-Case Sources Under the 2008 8-Hour Ozone National Ambient 
Air Quality Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is approving 
multiple state implementation plan (SIP) revisions submitted by the 
Commonwealth of Pennsylvania. These revisions were submitted by the 
Pennsylvania Department of Environmental Protection (PADEP) to 
establish and require reasonably available control technology (RACT) 
for individual major sources of volatile organic compounds (VOC) and/or 
nitrogen oxides (NOX) pursuant to the Commonwealth of 
Pennsylvania's conditionally approved RACT regulations. In this rule 
action, EPA is only approving source-specific RACT determinations 
(``case-by-case'' or alternative NOX emissions limits) for 
sources at nine major NOX and VOC emitting facilities 
located in Allegheny County. These RACT evaluations were submitted to 
meet RACT requirements for the 2008 8-hour ozone national ambient air 
quality standard (NAAQS). EPA is approving these revisions to the 
Pennsylvania SIP in accordance with the requirements of the Clean Air 
Act (CAA) and EPA's implementing regulations.

DATES: This final rule is effective on November 22, 2021.

ADDRESSES: EPA has established a docket for this action under Docket ID 
Number EPA-R03-OAR-2020-0575. All documents in the docket are listed on

SUPPLEMENTARY INFORMATION:

I. Background

    On May 7, 2021, EPA published a notice of proposed rulemaking 
(NPRM). 86 FR 24564. In the NPRM, EPA proposed approval of case-by-case 
RACT determinations for sources at ten facilities in Allegheny County, 
as EPA found that that the RACT controls for these sources met the CAA 
RACT requirements for the 2008 ozone NAAQS. PADEP, on behalf of 
Allegheny County Health Department (ACHD), initially submitted 
revisions to its SIP to address case-by-case NOx and VOC RACT for these 
sources on May 7, 2020 and supplemented the submittal on February 9, 
2021.
    Under certain circumstances, states are required to submit SIP 
revisions to address RACT requirements for both major sources of 
NOX and VOC and any source covered by control technique 
guidelines (CTG) for each ozone NAAQS. Which NOX and VOC 
sources in Pennsylvania are considered ``major,'' and are therefore 
subject to RACT, is dependent on the location of each source within the 
Commonwealth. Sources located in nonattainment areas would be subject 
to the ``major source'' definitions established under the CAA based on 
the area's current classification(s). In Pennsylvania, sources located 
in any ozone nonattainment areas outside of moderate or above are 
subject to the major source threshold of 50 tons per year (tpy) because 
of the Ozone Transport Region (OTR) requirements in CAA section 
184(b)(2).
    On May 16, 2016, PADEP submitted a SIP revision addressing RACT for 
both the 1997 and 2008 8-hour ozone NAAQS in Pennsylvania. PADEP's May 
16, 2016 SIP revision intended to address certain outstanding non-CTG 
VOC RACT, VOC CTG RACT and major source VOC and NOX RACT 
requirements for both standards. The SIP revision requested approval of 
Pennsylvania's 25 Pa. Code 129.96-100, Additional RACT Requirements for 
Major Sources of NOX and VOCs (the ``presumptive'' RACT II 
rule). Prior to the adoption of the RACT II rule, Pennsylvania relied 
on the NOX and VOC control measures in 25 Pa. Code 129.92-
95, Stationary Sources of NOX and VOCs, (the RACT I rule) to 
meet RACT for non-CTG major VOC sources and major NOX 
sources. The requirements of the RACT I rule remain approved into 
Pennsylvania's SIP and continue to be implemented as RACT.\1\ On 
September 26, 2017, PADEP submitted a letter, dated September 22, 2017, 
which committed to address various deficiencies identified by EPA in 
PADEP's May 16, 2016 ``presumptive'' RACT II rule SIP revision.
---------------------------------------------------------------------------

    \1\ The RACT I Rule was approved by EPA into the Pennsylvania 
SIP on March 23, 1998. 63 FR 13789. Through this rule, certain 
source-specific RACT I requirements will be superseded by more 
stringent requirements. See Section II of the preamble to this Final 
Rule.
---------------------------------------------------------------------------

    On May 9, 2019, EPA conditionally approved the RACT II rule based 
on the commitments PADEP made in its September 22, 2017 letter.\2\ 84 
FR 20274. In EPA's final conditional approval, EPA noted that PADEP 
would be required to submit, for EPA's approval, SIP revisions to 
address any facility-wide or system-wide NOX emissions 
averaging plans approved under 25 Pa. Code 129.98 and any case-by-case 
RACT determinations under 25 Pa. Code 129.99. PADEP committed to 
submitting these additional SIP revisions within 12 months of EPA's 
final conditional approval (i.e., by May 9, 2020). Through multiple 
submissions between 2017 and 2020, PADEP has submitted to EPA for 
approval various SIP submissions to implement its RACT II case-by-case 
determinations and NOX averaging plan limits. This 
rulemaking is based on EPA's review of one of these SIP submissions.
---------------------------------------------------------------------------

    \2\ On August 27, 2020, the Third Circuit Court of Appeals 
issued a decision vacating EPA's approval of three provisions of 
Pennsylvania's presumptive RACT II rule applicable to certain coal-
fired power plants. Sierra Club v. EPA, 972 F.3d 290 (3d Cir. 2020). 
None of the sources in this rule are subject to the three 
presumptive RACT II provisions at issue in that Sierra Club 
decision.
---------------------------------------------------------------------------

    The SIP revisions in this action only establish 2008 8-hour ozone 
NAAQS RACT requirements. Applicable RACT requirements under the CAA for 
sources located in Allegheny County for the 1997 8-hour ozone NAAQS 
were previously satisfied. See 78 FR 34584 (June 10, 2013).

II. Summary of SIP Revision and EPA Analysis

A. Summary of SIP Revision

    To satisfy a requirement from EPA's May 9, 2019 conditional 
approval, PADEP submitted to EPA SIP revisions addressing alternative 
NOX emissions limits and/or case-by-case RACT requirements 
for major sources in Pennsylvania subject to 25 Pa. Code 129.98 or 
129.99. Among the submitted SIP revisions were case-by-case RACT 
determinations for sources in Allegheny County, which PADEP submitted 
on behalf of ACHD. PADEP's submission included SIP revisions pertaining 
to case-by-case RACT determinations for the existing emissions units at 
each of the major sources of NOX and/or VOC that required a 
case-by-case RACT determination.
    In the case-by-case RACT determinations submitted by PADEP on 
behalf of ACHD, an evaluation was completed to determine if previously 
SIP-approved, case-by-case RACT emission limits or operational controls 
(herein referred to as RACT I and contained in RACT I permits) were 
more stringent than the new RACT II presumptive or case-by-case 
requirements. If more stringent, the RACT I requirements will continue 
to apply to the applicable source. If the new case-by-case RACT II 
requirements are more stringent than the RACT I requirements, then the 
RACT II requirements will supersede the prior RACT I requirements.\3\
---------------------------------------------------------------------------

    \3\ While the prior SIP-approved RACT I permit will remain part 
of the SIP, this RACT II rule will incorporate by reference the RACT 
II requirements through the RACT II permit and clarify the ongoing 
applicability of specific conditions in the RACT I permit.
---------------------------------------------------------------------------

    Here, EPA is approving SIP revisions pertaining to case-by-case 
RACT requirements for sources at nine major NOX and/or VOC 
emitting facilities in Allegheny County, as summarized in Table 1 in 
this document.\4\
---------------------------------------------------------------------------

    \4\ In its May 7, 2021 proposed rulemaking, EPA had proposed 
approval of SIP revisions pertaining to case-by-case RACT 
requirements for sources at ten major NOX and/or VOC 
emitting facilities in Allegheny County. At this time, EPA is only 
approving such SIP revisions at nine of those facilities and is not 
taking final action on the SIP revision related to the PPG 
Industries Inc. Springdale Plant.

--------------------------------------------------------------------------------------------------------------------------------------------------------

    The case-by-case RACT determinations submitted by PADEP, on behalf 
of ACHD, consist of an evaluation of all reasonably available controls 
at the time of evaluation for each affected emissions unit, resulting 
in an ACHD determination of what specific emission limit or control 
measures satisfy RACT for that particular unit. The adoption of new, 
additional, or revised emission limits or control measures to existing 
SIP-approved RACT I requirements were specified as requirements in new 
or revised Federally enforceable permits (hereafter RACT II permits) 
issued by ACHD to the source. These RACT II permits have been submitted 
as part of the Pennsylvania RACT SIP revisions for EPA's approval into 
the Pennsylvania SIP under 40 CFR 52.2020(d)(1). The RACT II permits 
submitted by PADEP are listed in the last column of Table 1 of this 
preamble, along with the permit effective date, and are part of the 
docket for this rule, which is available online at https://www.regulations.gov, Docket No. EPA-R03-OAR-2020-0575.\5\ EPA is 
incorporating by reference in the Pennsylvania SIP, via the RACT II 
permits, source-specific RACT emission limits and control measures 
under the 2008 8-hour ozone NAAQS for certain major sources of 
NOX and VOC emissions.
---------------------------------------------------------------------------

    \5\ The RACT II permits included in the docket for this rule are 
redacted versions of the facilities' Federally enforceable permits. 
They reflect the specific RACT requirements being approved into the 
Pennsylvania SIP via this final action.
---------------------------------------------------------------------------

B. EPA's Final Action

    PADEP's SIP revisions incorporate ACHD's determinations of source-
specific RACT II controls for individual emission units at major 
sources of NOX and/or VOC in Allegheny County, where those 
units are not covered by or cannot meet Pennsylvania's presumptive RACT 
regulation. After thorough review and evaluation of the information 
provided by ACHD in the SIP revision submittals for sources at nine 
major NOX and/or VOC emitting facilities in Allegheny 
County, EPA found that (1) ACHD's case-by-case RACT determinations and 
conclusions establish limits and/or controls on individual sources that 
are reasonable and appropriately considered technically and 
economically feasible controls and (2) ACHD's determinations are 
consistent with the CAA, EPA regulations, and applicable EPA guidance.
    ACHD, in its RACT II determinations, considered the prior source-
specific RACT requirements and, where more stringent, retained those 
prior RACT requirements as part of its new RACT determinations. In the 
NPRM, EPA proposed to find that all the proposed revisions to 
previously SIP-approved RACT requirements would result in equivalent or 
additional reductions of NOX and/or VOC emissions. The 
proposed revisions should not interfere with any applicable 
requirements concerning attainment of the NAAQS, reasonable further 
progress, or other applicable requirements under section 110(l) of the 
CAA.
    Other specific requirements of the 2008 8-hour ozone NAAQS case-by-
case RACT determinations and the rationale for EPA's proposed action 
are explained more thoroughly in the NPRM, and its associated technical 
support document (TSD), and will not be restated here.

III. Public Comments and EPA Responses

    EPA received comments from three commenters on the May 7, 2021 
NPRM. 86 FR 24564. A summary of the comments and EPA's responses are 
discussed in this section. A copy of the comments can be found in the 
docket for this rule action.
    Comment 1: Two commenters indicated that the permit for U.S Steel 
Mon Valley Works--Clairton listed in the table of the document should 
be Permit No. 0052-I020b effective, December 11, 2021 rather than 
Permit No., 0052-I020a effective, December 7, 2021.
    Response 1: EPA agrees with commenters and has corrected the permit 
number and effective date indicated in the tables of this preamble.
    Comment 2: One commenter identified that there is an appeal of the 
RACT II permit for the PPG Springdale facility pending before ACHD's 
Hearing Officer and, therefore, requested EPA not take final action on 
the SIP revision.
    Response 2: EPA is not taking final action on the PPG Springdale 
RACT determination at this time and will act on this SIP revision in a 
later rulemaking. EPA will respond to the comment at that time.

IV. Final Action

    EPA is approving case-by-case RACT determinations for sources at 
nine major NOX and VOC emitting facilities in Allegheny 
County, as required to meet obligations pursuant to the 2008 8-hour 
ozone NAAQS, as revisions to the Pennsylvania SIP.

V. Incorporation by Reference

    In this document, EPA is finalizing regulatory text that includes

[[Page 58223]]

incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of source-
specific RACT determinations and NOx averaging plan limits under the 
1997 and 2008 8-hour ozone NAAQS for certain major sources of VOC and 
NOX in Allegheny County. 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 rule of EPA's approval, and will be incorporated by reference in 
the next update to the SIP compilation.\6\
---------------------------------------------------------------------------

    \6\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

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);
     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. Section 804, however, exempts from section 801 the 
following types of rules: Rules of particular applicability; rules 
relating to agency management or personnel; and rules of agency 
organization, procedure, or practice that do not substantially affect 
the rights or obligations of non-agency parties. 5 U.S.C. 804(3). 
Because this is a rule of particular applicability, EPA is not required 
to submit a rule report regarding this action under section 801.

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 December 20, 2021. 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 Pennsylvania's NOX and VOC RACT 
requirements for nine facilities for the 2008 8-hour ozone NAAQS may 
not be challenged later in proceedings to enforce its requirements. 
(See section 307(b)(2).)
