ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R03-OAR-2019-0686; FRL-10014-39-Region 3]


Approval and Promulgation of Air Quality Implementation Plans; 
Pennsylvania; Reasonably Available Control Technology Determinations 
for Case-by-Case Sources Under the 1997 and 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 
nitrogen oxides (NOX) pursuant to the Commonwealth of 
Pennsylvania's conditionally approved RACT regulations. In this action, 
EPA is only approving source-specific (also referred to as ``case-by-
case'') RACT determinations for 19 major sources. These RACT 
evaluations were submitted to meet RACT requirements for the 1997 and 
2008 8-hour ozone national ambient air quality standards (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 16, 2020.

ADDRESSES: EPA has established a docket for this action under Docket ID 
Number EPA-R03-OAR-2019-0686. All documents in the docket are listed on 
the https://www.regulations.gov website. Although listed in the index,

SUPPLEMENTARY INFORMATION:

I. Background

    On March 20, 2020, EPA published a notice of proposed rulemaking 
(NPRM). 85 FR 16021. In the NPRM, EPA proposed approval of case-by-case 
RACT determinations for 19 sources in Pennsylvania for the 1997 and 
2008 8-hour ozone NAAQS. The case-by-case RACT determinations for these 
19 sources were included in SIP revisions submitted by PADEP on August 
14, 2017, November 21, 2017, April 26, 2018, June 26, 2018, and October 
29, 2018.
    Under certain circumstances, states are required to submit SIP 
revisions to address RACT requirements for major sources of 
NOX and VOC or any source category for which EPA has 
promulgated control technique guidelines (CTG) for each ozone NAAQS. 
Which NOX and VOC sources in Pennsylvania are considered 
``major,'' and therefore to be addressed for RACT revisions, 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 their 
classification. In the case of Pennsylvania, sources located in any 
areas outside of moderate or above nonattainment areas, as part of the 
Ozone Transport Region (OTR), are subject to source thresholds of 50 
tons per year (tpy). CAA section 184(b).
    On May 16, 2016, PADEP submitted a SIP revision addressing RACT 
under 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 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 sources are obligated to 
follow them.\1\ On September 26, 2017, PADEP submitted a supplemental 
SIP, dated September 22, 2017, which committed to address various 
deficiencies identified by EPA in their 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.
---------------------------------------------------------------------------

    On May 9, 2019, EPA conditionally approved the RACT II rule based 
on the commitments PADEP made in its September 22, 2017 supplemental 
SIP. 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 averaging plan 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, 
specifically May 9, 2020. The SIP revisions addressed in this rule are 
part of PADEP's efforts to meet the conditions of its supplemental SIP 
and EPA's conditional approval of the RACT II Rule.

II. Summary of SIP Revisions and EPA Analysis

A. Summary of SIP Revisions

    To satisfy a requirement from EPA's May 9, 2019 conditional 
approval, PADEP has submitted to EPA SIP revisions addressing case-by-
case RACT requirements for major sources in Pennsylvania subject to 25 
Pa. Code 129.99. In the Pennsylvania RACT SIP revisions, PADEP included 
a case-by-case RACT determination for the existing emissions units at 
each of the major sources of NOX and/or VOC that required a 
source-specific RACT determination. In PADEP's RACT determinations, 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.\2\ Here, EPA 
is taking action on SIP revisions pertaining to case-by-case RACT 
requirements for 19 major sources of NOX and/or VOC in 
Pennsylvania as summarized in Table 1.
---------------------------------------------------------------------------

    \2\ While the prior SIP-approved RACT I permit will remain part 
of the SIP, this RACT II rulemaking 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.

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

    The case-by-case RACT determinations submitted by PADEP consist of 
an evaluation of all reasonably available controls at the time of 
evaluation for each affected emissions unit, resulting in a PADEP 
determination of what specific emission limit or control measures, if 
any, 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 PADEP to the source. The RACT II permits, which revise or 
adopt additional source-specific limits and/or controls, have been 
submitted as part of the Pennsylvania RACT SIP revisions for EPA's 
approval in 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-2019-0686.\3\ EPA is 
incorporating by reference in the Pennsylvania SIP, via the RACT II 
permits, source-specific RACT emission limits and control measures 
under the 1997 and 2008 8-hour ozone NAAQS for certain major sources of 
NOX and VOC emissions.
---------------------------------------------------------------------------

    \3\ The RACT II permits are redacted versions of a facility's 
Federally enforceable permits and reflect the specific RACT 
requirements being approved into the Pennsylvania SIP.
---------------------------------------------------------------------------

B. EPA's Proposed Action

    PADEP's SIP revisions incorporate its determinations of source-
specific RACT II controls for individual emission units at major 
sources of NOX and/or VOC in Pennsylvania, 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 PADEP in its five SIP revision submittals for 19 major 
sources of NOX and/or VOC in Pennsylvania, EPA proposed to 
find that PADEP'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.
    PADEP, in its RACT II determinations, considered the prior source-
specific RACT I requirements and, where more stringent, retained those 
RACT I 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 I requirements would result in equivalent 
or additional reductions of NOX and/or VOC emissions. The 
proposed revisions should not interfere with any applicable requirement 
concerning attainment or

[[Page 65708]]

reasonable further progress with the NAAQS or section 110(l) of the 
CAA.
    Other specific requirements of Pennsylvania's 1997 and 2008 8-hour 
ozone NAAQS case-by-case RACT determinations and the rationale for 
EPA's proposed action were 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 comments from 27 commenters on the March 20, 2020 
NPRM. 85 FR 16021. 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 action.
    Comment 1: EPA received two nearly identical comments that stated, 
``EPA should extend the comment period for this and all rulemakings 
until the global pandemic of SARS-COV-2 is over.'' The commenters 
further stated that ``EPAs [sic] decision to continue the regulatory 
process during the COVID-19 pandemic is unlawful because EPA is forcing 
the public to choose between their own health and safety or participate 
in this public process.'' The commenters noted that environmental 
advocacy groups have asked EPA to put rulemakings on hold because they 
``violate the APA and don't allow the public to fully review EPA's 
decision while a global pandemic is in full force.'' The commenters 
request EPA extend the public comment period for an additional 30 days 
after the ``President's National Emergency Order or Pennsylvania's 
Emergency Order are pulled back.'' Lastly, one commenter stated that 
``EPA has released numerous orders waiving environmental requirements 
such as monitoring required by Part 75 and waiving enforcement of 
environmental rules due to COVID-19, recognizing that industry may not 
be able to comply with these rules due to the global pandemic but EPA 
still expects the public to review and comment on rulemakings such as 
this.''
    Response 1: EPA disagrees with the commenters' assertion that it 
should extend all public comment periods until the end of the ``global 
pandemic of SARS-COV-2.'' EPA also disagrees that ``EPAs decision to 
continue the regulatory process during the COVID-19 pandemic is 
unlawful because EPA is forcing the public to choose between their own 
health and safety or participate in this public process.'' Prior to the 
COVID-19 pandemic, EPA was providing the public with online access to 
rulemaking actions and supporting documentation. During the pandemic, 
EPA has continued to make those materials available to the public; this 
proposed rulemaking was no exception. EPA also disagrees that its 
action, proposing approval of RACT for 19 facilities in Pennsylvania, 
violates the Administrative Procedures Act (APA). EPA followed 
necessary APA procedures for this proposed rulemaking, which included 
providing the public with a 30-day comment period and access to all 
supporting documentation related to the proposed rulemaking.
    Finally, EPA understands the commenters' concerns with respect to 
the challenges the public is facing with respect to COVID-19 and the 
global pandemic, but that alone is not a reason for EPA to extend its 
public comment period for this proposed rulemaking. The commenters 
failed to provide new information or a compelling reason as to why EPA 
should extend the public comment period for this specific rulemaking 
action. The public was given adequate time and access to information 
necessary to formulate comments on this rule. Therefore, EPA continues 
to believe that the 30-day comment period was appropriate and did not 
feel compelled to extend the public comment period, as requested by the 
commenters. In this action, EPA is finalizing its rulemaking action in 
accordance with APA requirements.
    Comment 2: One commenter questioned why EPA is reproposing this 
action, since it already proposed action on these RACT permits in July 
2019 under Docket EPA-R03-OAR-2017-0290. The commenter then goes on to 
assert that ``EPA is attempting to circumvent the comments submitted 
under this prior proposal and trying to avoid responding to these 
comments!'' The commenter further asserts that EPA should be ``forced 
to publish the comments and properly respond to them'' noting that the 
``previous proposal received 66 comments, and then for some reason most 
of the documents associated with that proposal have disappeared from 
the docket.'' The commenter makes statements that ``what EPA is doing 
is illegal'' and responding to those comments is ``required by the 
APA'' and that EPA should ``respond to each of them as required.'' 
Lastly, the commenter attempts to ``incorporate by reference all those 
comments into this comment and request EPA to respond to those comments 
as if they were copied here verbatim.''
    Response 2: EPA acknowledges that it previously proposed to approve 
certain source-specific RACT determinations for 21 facilities in its 
July 31, 2019 NPRM. See 84 FR 37167. In its current proposed 
rulemaking, EPA explained that on August 30, 2019, the last day of the 
comment period for the July 31, 2019 NPRM, EPA became aware through a 
comment submitted to Regulations.gov that one of the files contained in 
the SIP submission--which EPA made public in the docket for that 
rulemaking proposing to approve the submission (Docket No. EPA-R03-OAR-
2017-0290-0064)--contained potential CBI. EPA restricted public access 
in Regulations.gov to that file containing potential CBI the same day, 
prior to the end of the comment period. On September 30, 2019, EPA 
became aware through additional comments submitted to Regulations.gov 
during the comment period that additional potential CBI was contained 
in other files EPA had posted to Docket No. EPA-R03-OAR-2017-0290-0064. 
EPA restricted public access in Regulations.gov to the entire docket 
that same day. In accordance with EPA's CBI regulations at 40 CFR part 
2, subpart B, EPA has contacted each business affected by the inclusion 
of potential CBI in the docket files to inform them that potential CBI 
was made publicly available on Regulations.gov, and afforded each 
business an opportunity to assert a claim of business confidentiality 
for any of their information posted by EPA to Docket No. EPA-R03-OAR-
2017-0290-0064. See 85 FR 16021, 16022 (March 20, 2020).
    EPA subsequently proposed to approve 19 of the 21 Pennsylvania 
case-by-case RACT determinations in this new rulemaking. EPA has 
established a docket for this new rulemaking that does not include any 
materials claimed as CBI (Docket ID No. EPA-R03-OAR-2019-0686). In 
EPA's NPRM, commenters were instructed to submit any comments they have 
on EPA's proposed approval of these 19 case-by-case RACT determinations 
to this new docket number. Because this is a new rulemaking, EPA will 
not consider any comments on its prior proposal made at Docket ID No. 
EPA-R03-OAR-2017-0290-0064. The proposal that is being finalized here 
specifically stated that ``[a]ny prior comments will need to be 
resubmitted to Docket ID No. EPA-R03-OAR-2019-0686 during the comment 
period for this proposed rulemaking for EPA to consider them.'' Id. 
Also, the NPRM contains standard language explaining that the written 
comment is considered the official comment and should include all the 
points the commenter wants to make. Comments or comment content outside 
the primary

[[Page 65709]]

submission are generally not considered.
    For the reasons stated here, and in its March 20, 2020 NPRM, EPA 
disagrees with the commenter's assertion that it is trying to 
``circumvent the comments'' or that it is doing something ``illegal.'' 
To the contrary, EPA made its intentions clear to the public that this 
was a new rulemaking and provided the public with the legally required 
30-day public comment period. In its March 20, 2020 NPRM, EPA 
articulated that the previous comments would not be responded to and 
the public would be required to resubmit any comments based on the 
documentation provided in the docket for the March 20, 2020 rulemaking. 
Similarly, the commenter is not able to ``incorporate by reference all 
those comments into this comment and request EPA to respond to those 
comments as if they were copied here verbatim.'' As instructed, if the 
commenter wanted EPA to address comments made on the previous July 31, 
2019 NPRM, the commenter needed to resubmit those specific comments 
during this public comment period and EPA would respond to them, as 
required by the APA.
    Comment 3: The commenter asserts that for the sources at Blommer 
Chocolate Company (Blommer), EPA is proposing to approve 12-month 
rolling tpy VOC limits as case-by-case RACT despite EPA policy guidance 
documents that require daily VOC RACT limits and in no case should 
those limits exceed 30-day averages because ozone is a short-term 
standard. The commenter cites several prior comments that EPA made to 
PADEP that suggested that these 12-month rolling tpy limits proposed as 
case-by-case VOC RACT for the sources at Blommer Chocolate are 
inadequate based on existing policy guidance. The commenter demands 
that EPA disapprove PADEP's case-by-case RACT determination for Blommer 
Chocolate and requests re-evaluation so that appropriate VOC emission 
limits with averages no greater than 30-days can be imposed on the 
sources at this facility.
    Response 3: While the commenter does not specify the particular EPA 
policy guidance documents being referenced, EPA agrees that existing 
guidance does highlight the need for emission controls that are 
reasonably consistent with protecting a short-term NAAQS such as ozone. 
In those cases where an emission limit for a RACT control can be 
quantified, EPA guidance states that averaging periods for such limits 
should be as short as practicable and in no case longer than 30 
days.\4\
---------------------------------------------------------------------------

    \4\ See the January 20, 1984 EPA guidance memorandum titled 
``Averaging Times for Compliance with VOC Emission Limits--SIP 
Revision Policy.''
---------------------------------------------------------------------------

    Since the 1970's, EPA has consistently defined RACT as the lowest 
emission limit that a particular source is capable of meeting by the 
application of the control technology that is reasonably available 
considering technological and economic feasibility. The establishment 
of case-by-case RACT requirements to reduce VOC and/or NOX 
emissions considers not only numeric emission limits, but also design 
and equipment specifications, operational and throughput constraints 
and work practice standards. Each of these requirements can take 
different forms depending on the types of processes and emissions at a 
facility. For example, emission controls can include material content 
limits (pound (lb) per gallon (gal) material used) or emission limits 
(lb per hour (hr) limits, lb per day limits, and lb per month limits). 
These forms of controls are all considered suitable RACT requirements. 
Each source is different and not every form of an emission control is 
possible for every source. For example, in some cases, one or more of 
the various forms of short-term emission limits may be infeasible based 
on an evaluation of the RACT-subject facility. The commenter is also 
correct that EPA provided comments to PADEP when reviewing a draft 
permit that questioned the adequacy and enforceability of some of the 
proposed limits at Blommer, including the tpy limit, based on EPA 
guidance.
    As determined by PADEP, the technically feasible control strategies 
for the nine sources subject to case-by-case RACT at Blommer were not 
economically feasible, except for the good operating practices option. 
Having concluded through the RACT evaluation process that the type of 
control options available for the Bloomer sources (upon which short-
term limits could be imposed) were not technically or economically 
feasible, PADEP imposed good operating practices along with the 
requirement to install, maintain, and operate each source in accordance 
with manufacturer's specifications as the RACT requirements for these 
sources.\5\ Additionally, PADEP included source-specific recordkeeping 
and reporting requirements. Monthly recordkeeping requirements are 
required for calculating both VOC emissions and the amount of cocoa 
nibs processed.\6\
---------------------------------------------------------------------------

    \5\ See PADEP Technical Review Memo, dated February 1, 2017, 
which is part of the record for this docket.
    \6\ For example, see Blommer redacted Permit No. 46-00198, 
Section D, Source ID 105, Condition IV. #004, which is part of the 
record for this docket and will be incorporated by reference into 
the SIP.
---------------------------------------------------------------------------

    In addition to these RACT requirements, PADEP also included in its 
SIP submittal a request to incorporate existing permitted annual VOC 
emission limits for the sources into the Pennsylvania SIP. Those annual 
limits were previously established for each source through a Best 
Available Technology (BAT) evaluation at the time each source was 
permitted, and ensure the SIP requires the conditions under which the 
PADEP analyzed RACT feasibility.\7\ In response to PADEP's request, EPA 
is approving those annual limits into the SIP in addition to the RACT 
requirements PADEP determined to be technically and economically 
feasible for Blommer. Because Pennsylvania analyzed what should be RACT 
under operating conditions that included annual limits from the Blommer 
permit, and PADEP included those requirements in its SIP submittal to 
us, EPA is incorporating those annual emission limits into the SIP not 
as RACT control limits but for the purpose of SIP strengthening. For 
these reasons, we consider the annual limits to be separate from RACT 
and believe the commenter's assertion is misplaced.\8\
---------------------------------------------------------------------------

    \7\ See Alternative RACT Compliance Proposal, Blommer Chocolate 
Company, October 2016, which is part of the record for this docket. 
BAT is defined by Pennsylvania as ``[e]quipment, devices, methods, 
or techniques as determined by the Department which will prevent, 
reduce, or control emissions of air contaminants to the maximum 
degree possible and which are available or may be made available.'' 
25 Pa. Code 121.1.
    \8\ EPA notes that PADEP, in its RACT SIP revisions for the 
following facilities (The Boeing Co.; JW Aluminum Company; Ward 
Manufacturing, LLC; Wood-Mode Inc.; Texas Eastern Transmission, 
L.P.--Bernville; Texas Eastern Transmission, L.P.--Shermans Dale; 
Texas Eastern Transmission, L.P.--Perulack; Texas Eastern 
Transmission, L.P.--Grantville; Texas Eastern Transmission, L.P.--
Bechtelsville; NRG Energy Center Paxton, LLC; Containment Solutions, 
Inc.; Jeraco Enterprises, Inc.;, and Foam Fabricators, Inc.) 
included some form of annual limits in the RACT II permits for those 
facilities. Even though a public comment was not submitted 
concerning the annual limits for these other facilities, EPA wishes 
to clarify that it is not approving any such annual limits as RACT 
control limits. Rather, because PADEP conducted its RACT analysis 
under operating conditions that included annual limits from the 
existing facility permit, and PADEP included those requirements in 
its SIP submittal to us, EPA is incorporating those annual limits 
into the SIP not as RACT control limits but for the purpose of SIP 
strengthening.
---------------------------------------------------------------------------

    Comment 4: The commenter states that EPA is proposing case-by-case 
VOC RACT for the sources at Jeraco Enterprises, Inc. (Jeraco) to be in 
compliance with 40 CFR part 63 subparts WWWW and PPPP (National 
Emission Standards for Hazardous Air

[[Page 65710]]

Pollutants (NESHAP) for Surface Coating of Plastic Parts and Products; 
NESHAP for Reinforced Plastic Composites Production). The commenter 
states that EPA does not quantify how much VOC emission reductions this 
might achieve. According to the commenter, VOC emissions cannot be 
controlled under this strategy because while some hazardous air 
pollutants (HAPs) are VOCs, not all VOCs are HAPs. Thus, the commenter 
asserts that EPA must evaluate what percentage of VOC reductions are 
being achieved through the control of HAPs at the sources at Jeraco, 
and from there, determine what additional controls are necessary to 
address non-HAP VOC emissions.
    Response 4: EPA disagrees with the commenter's claim that case-by-
case VOC RACT for the five sources at Jeraco is in compliance with 40 
CFR part 63 subparts WWWW and PPPP. While the commenter is correct in 
stating that the facility is indeed subject to NESHAPs WWWW and PPPP, 
PADEP did not determine that the five sources could meet RACT 
requirements only by meeting the NESHAP requirements. EPA also 
disagrees with the commenter on the alleged inadequacy of PADEP's 
evaluation of VOC emissions at the facility. PADEP followed the RACT 
provisions of 25 Pa. Code 129.99 and evaluated the technical and 
economic feasibility of potential VOC control options for the five 
case-by-case sources at Jeraco. Through that evaluation, PADEP 
considered the control of all VOCs, not just VOCs that were HAPs. As 
PADEP evaluated potential control options for all VOCs, there was no 
need to evaluate what percentage of VOC control is achieved through the 
applicable NESHAP as suggested by the commenter because compliance with 
the NESHAP, which was an existing baseline condition at the facility, 
was not one of the control requirements considered for purposes of 
fulfilling RACT requirements.
    The redacted version of the facility's permit (No. 49-00014), which 
is being incorporated by reference into the SIP and is available in the 
docket for this action, documents the RACT requirements to be 
incorporated into the SIP for this facility. These requirements are 
summarized in the TSD (under the heading ``PADEP Conclusions''). The 
requirements for the Jeraco sources include, in most instances, 
specific VOC emission limitations, VOC content restrictions, material 
usage requirements, and detailed work practice requirements to minimize 
VOC emissions.\9\

    Comment 5: The commenter asserts that for the boardmill line at 
Armstrong World Industries, Inc. (Armstrong), there is a discrepancy 
between what is reported as the source's exhaust temperature and the 
moisture content of that exhaust in the evaluation of activated carbon 
adsorption as a VOC control versus that which is reported for these 
measures during the evaluation of the catalytic oxidizer. The commenter 
demands that EPA disapprove PADEP's case-by-case RACT determination for 
Armstrong and requests re-evaluation of these technologies with the 
actual exhaust temperature and moisture content.
    Response 5: EPA disagrees that there is a discrepancy in what is 
being reported as the boardmill line source's exhaust temperature and 
moisture content when evaluating the technical feasibility of the two 
VOC control strategies (activated carbon adsorption/zeolite adsorption 
and a catalytic oxidizer) as RACT. Actual exhaust temperatures and 
moisture content (i.e., saturation) for the two different exhaust 
streams (at the venturi scrubber inlet and outlet) have been provided 
by Armstrong. Stack test results for the boardmill line, pre and post-
scrubber, with data on both exhaust temperature and moisture content 
are provided in Armstrong's RACT II proposal.\10\ Table 2-1 (scrubber 
inlet) of that report shows exhaust temperatures averaging 344 degrees 
Fahrenheit ([deg]F) and 341 [deg]F for the North and South locations 
respectively. Moisture content averages 36.6 percent (%) and 36.1%, 
respectively. Table 2-2 (scrubber outlet) of that report shows exhaust 
temperatures averaging 170 [deg]F for both locations and moisture 
content averaging 37.9% and 37.8%, respectively, for both locations.
---------------------------------------------------------------------------

    \10\ See TRC Environmental Corporation's Report for Armstrong 
World Industries, Marietta Boardmill Dryer, Marietta, Pennsylvania, 
which is part of the record for this docket.
---------------------------------------------------------------------------

    These temperature and moisture content values were used 
consistently in Armstrong's RACT analysis. In the evaluation of the 
adsorption control technology, the company cites vendor information 
that states that adsorbents will not function in a saturated gas stream 
or function for a process gas with temperatures greater than 104 
[deg]F.\11\ The same letter also explains that catalytic oxidation is 
not feasible at the scrubber exhausts because the temperature is too 
low and would have to be significantly increased to about 650 [deg]F.

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

    Comment 6: The commenter states that EPA is proposing case-by-case 
VOC RACT for the sources at Containment Solutions--Mt. Union Plant 
(Containment Solutions) to be in compliance with 40 CFR part 63 subpart 
WWWW (NESHAP for Reinforced Plastic Composites Production). The 
commenter states that EPA does not quantify how much VOC emission 
reductions this might achieve. The commenter asserts that EPA must 
evaluate what percentage of VOC reductions are being achieved through 
the control of HAPs at the layup source at Containment Solutions.
    Response 6: The commenter is partially correct in that for the 
single source at Containment Solutions that is subject to a case-by-
case VOC RACT determination (the layup area), PADEP has determined RACT 
to include, among other requirements, compliance with NESHAP WWWW. 
However, PADEP's RACT determination did not rely solely on compliance 
with NESHAP WWWW. EPA disagrees with the commenter on the alleged 
inadequacy of PADEP's evaluation of VOC emissions at the facility. 
PADEP followed the RACT provisions of 25 Pa. Code 129.99 to evaluate 
the technical and economic feasibility of potential VOC control options 
for the case-by-case source at Containment Solutions. Through that 
evaluation, PADEP considered the control of all VOCs, not just VOCs 
that were HAPs. As PADEP evaluated potential control options for all 
VOCs, there was no need to evaluate what percentage of VOC control is 
achieved through the applicable NESHAP as suggested by the commenter 
because compliance with the NESHAP was an existing baseline condition 
at the facility.
    Other RACT requirements imposed by PADEP for this source also 
include a restriction on total resin use (shall not exceed 12,910,000 
lbs per 12-month consecutive period) and specific work practice 
requirements (such as the use of a ``tank fabrication'' resin pouring 
layup method and a ban on the use of solvent-based resin cleanup 
solutions). PADEP also included specific recordkeeping and reporting 
requirements.\12\

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

    Comment 7: The commenter asserts that EPA does not specify the

[[Page 65711]]

monitoring and recordkeeping being required as RACT for Containment 
Solutions.
    Response 7: EPA disagrees with this comment. Specific monitoring 
and recordkeeping requirements associated with the RACT requirements 
for the layup area (Source ID 101) at Containment Solutions can be 
found in the redacted version of the facility's permit. Daily records, 
which inherently require monitoring, are required on resin 
identification, resin usage, VOC emissions and hours of operation.\13\

    Comment 8: The commenter asserts that the PADEP economic benchmark 
for case-by-case RACT determinations is too low and not appropriate for 
all case-by-case evaluations, such as those for Texas Eastern 
Bechtelsville. The commenter states that an absolute cost threshold 
should not be used. The commenter goes on to discuss New Jersey's RACT 
program in comparison to Pennsylvania's, stating that New Jersey's 
program does not consider an absolute cost threshold, and the range of 
dollar per ton of NOX removed in the New Jersey evaluations 
allows for more control options to be considered economically feasible.
    Response 8: EPA is aware that Pennsylvania considered cost-
effectiveness levels ($/ton removed) that are lower than other states, 
such as New Jersey as the commenter notes, when developing the RACT II 
rule. However, EPA has not set a single cost, emission reduction, or 
cost-effectiveness figure to fully define cost-effectiveness in meeting 
the NOX or VOC RACT requirement. Therefore, states have the 
discretion to determine what costs are considered reasonable when 
establishing RACT for their sources. Each state must make and defend 
its own determination on how to weigh these values in establishing 
RACT.
    As PADEP explained in its RACT II rulemaking, it did not establish 
a bright-line cost effectiveness threshold in determining what is 
economically reasonably for purposes of defining RACT.\14\ Instead, it 
developed as guidance a cost-effectiveness threshold of $2,800 per ton 
of NOX controlled and $5,500 per ton of VOC controlled for 
RACT. Pennsylvania also determined that even evaluating control 
technology options with an additional 25% margin, an upper bound cost-
effectiveness threshold of $3,500 per ton NOX controlled and 
$7,000 per ton VOC controlled, would not affect the add-on control 
technology decisions required by RACT.\15\ Pennsylvania determined that 
these higher cost-effectiveness thresholds did not impact the 
determination of what add on control technology was feasible. 
Pennsylvania also reviewed examples of benchmarks used by other states: 
Wisconsin, $2,500 per ton NOX; Illinois, $2,500--$3,000 per 
ton NOx; Maryland, $3,500--$5,000 per ton NOX; 
Ohio, $5,000 per ton NOX; and New York, $5,000--$5,500 per 
ton NOX.\16\

Rulemaking RACT Requirements for Major Sources of NOX and

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

    In its conditional approval of Pennsylvania's overall RACT II 
program, EPA found that PADEP's cost effectiveness thresholds are 
reasonable and reflect control levels achieved by the application and 
consideration of available control technologies, after considering both 
the economic and technological circumstances of Pennsylvania's own 
sources. See 84 FR 20274, 20286 (May 9, 2019).
    Comment 9: The commenter requests that EPA and PADEP re-evaluate 
Texas Eastern Bechtelsville's RACT analysis, taking into account the 
NOX emission reductions achieved in practice by other 
existing sources in New Jersey and other states. The commenter cites a 
similar natural gas compressor station operated by Texas Eastern in New 
Jersey that has two identical turbines (two Dresser Clark DC-990 
turbines) as those found at Texas Eastern Bechtelsville. The commenter 
states that under the New Jersey RACT program, in order to comply with 
the presumptive NOX RACT limit of 42 parts per million by 
volume, dry (ppmvd) at 15% oxygen (O2), the 
facility proposed replacement of the turbines with two new turbines 
that utilize low NOX emissions technology and will reduce 
NOX emissions from 172.5 ppmvd to 9 
ppmvd at 15% O2 (or 25 tpy).
    Response 9: The commenter is correct that the Texas Eastern 
Bechtelsville facility does appear to have one source (Source ID 101, 
Dresser Clark DC 990 turbine) which is similar if not identical to the 
two sources the commenter discusses that are allegedly found at the 
natural gas compressor station in New Jersey. However, under the 
Pennsylvania RACT program, Source ID 101 at Texas Eastern Bechtelsville 
will meet Pennsylvania's presumptive RACT requirements per 25 Pa. Code 
129.97(g)(2)(iii) and 129(g)(2)(iv). It is not part of the facility's 
case-by-case RACT proposal and EPA is not taking any action on Source 
ID 101 in this rulemaking. The presumptive RACT determination for 
Source ID 101 is not part of this rulemaking action, thus the comment 
is outside the scope of this action.
    Comment 10: The commenter asks EPA to re-evaluate the RACT 
determination for the two boilers at NRG Energy Center Paxton, LLC 
(NRG), specifically for the boilers when operating on No. 6 fuel oil. 
The commenter states that the proposed NOX short-term 
emission limit of 0.44 pound per million British thermal units (lb/
MMBtu) is ``entirely too high for a boiler of this size.'' The 
commenter suggests that switching to No. 2 fuel oil and/or a permanent 
restriction on the use of No. 6 residential fuel oil to only emergency 
situations when natural gas is unavailable should be evaluated as RACT.
    Response 10: EPA continues to find that Pennsylvania's RACT 
determination for Boiler Nos. 13 and 14 (Source IDs 032 and 033) at NRG 
is reasonable given the technological and economic feasibility analysis 
required by 25 Pa. Code Sections 129.92 and 129.99. Through the RACT 
analysis, PADEP reviewed the available control options with a 
reasonable potential for application at the source and determined that 
the short-term NOX emission limit of 0.44 lb/MMBtu for 
Boilers 13 and 14 when operating on No. 6 fuel oil is the appropriate 
RACT requirement.
    Through the RACT II process, PADEP also added new requirements for 
Boilers 13 and 14. Under the new RACT II permit, each of the two 
boilers will now be subject to an annual NOX emission limit 
of 46 tpy, a limit that is in addition to the short-term RACT limit and 
strengthens the SIP. Furthermore, each boiler will now be subject to 
operating restrictions on fuel usage--No. 6 fuel oil limited to 
1,533,300 gallons per year (gal/yr) and natural gas limited to 
584,000,000 cubic feet/year.\17\ PADEP had added these requirements to 
reflect the fact that these are not full time operating units and 
impose the conditions upon which the feasibility analysis was 
conducted. Because Pennsylvania analyzed what should be RACT under 
operating conditions that included annual limits from the NRG permit, 
and PADEP included those requirements in its SIP submittal to us, EPA 
is incorporating those annual emission limits into the SIP not as

[[Page 65712]]

RACT control limits but for the purpose of SIP strengthening.\18\

RACT II Requirements for Source IDs 032 and 033, which is being

this docket.
    \18\ As a result of reviewing PADEP's RACT II determination for 
NRG in response to this comment, EPA has also updated its TSD for 
this facility to clarify its RACT I status. The updated TSD has been 
added to the docket of this rulemaking.
---------------------------------------------------------------------------

    Comment 11: The commenter suggests that EPA should disapprove the 
short-term NOX emission limit of 116 parts per million (ppm) 
at Texas Eastern Grantville because the limit is too high. The 
commenter cites stack test results in which the applicable sources were 
able to maintain a NOX emission rate of 84.3 ppm with the 
highest run being 86.8 ppm. The commenter demands that EPA send the 
RACT determination back to the state for a re-evaluation showing the 
lowest achievable emission limit for the sources.
    Response 11: EPA disagrees with the commenter on the stack test 
results referenced in the comment. The values included in the comment 
refer to stack test results for the facility's Dresser Clark DC 990 
turbine (Source ID 032), which is subject to presumptive RACT 
requirements at 25 Pa. Code 129.97(g)(2)(iii) and (iv).\19\ The test 
results do not refer to the Westinghouse W52 turbines (Source IDs 033 
and 034), which are subject to this case-by-case RACT rulemaking.

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

    The two Westinghouse W52 turbines (Source IDs 033 and 034) have a 
short-term NOX limit of 116 ppm. Assuming the commenter was 
objecting to the 116 ppm short-term NOX limit for the 
Westinghouse turbines, EPA continues to find that Pennsylvania's RACT 
determinations for those turbines are reasonable given the analysis of 
technological and economic feasibility, which is part of the record for 
this docket, and that the short-term NOX emission limit of 
116 ppm for these turbines is appropriate. As part of the case-by-case 
NOX RACT analysis, the facility evaluated the technical and, 
where appropriate, economic feasibility of available control strategies 
for the two Westinghouse turbines and determined that there were no 
reasonably available control technologies that were technically or 
economically feasible for the conditions at this facility. 
Technological and economic feasibility are how EPA analyzes what is 
RACT for purposes of implementation of the ozone NAAQS--the standard is 
not lowest achievable emission rates, as suggested by the 
commenter.\20\
---------------------------------------------------------------------------

    \20\ Since the 1970's, EPA has consistently defined ``RACT'' as 
the lowest emission limit that a particular source is capable of 
meeting by the application of the control technology that is 
reasonably available considering technological and economic 
feasibility. See December 9, 1976 memorandum from Roger Strelow, 
Assistant Administrator for Air and Waste Management, to Regional 
Administrators, ``Guidance for Determining Acceptability of SIP 
Regulations in Non-Attainment Areas,'' and 44 FR 53762 (September 
17, 1979).
---------------------------------------------------------------------------

    PADEP imposed, as a RACT II requirement, a continuation of the 
current RACT I short-term NOX limit of 116 ppmvd 
at 15% O2 at all times. This limit is based on a statistical 
analysis of historical stack test results (for Texas Eastern's entire 
fleet of Westinghouse W52 turbines in Pennsylvania). The analysis 
showed that lowering the short-term emission rate without the 
availability of any additional feasible controls would present a 
significant compliance risk.\21\ Ultimately, Pennsylvania agreed with 
the facility's evaluation of feasible controls and that case-by-case 
NOX RACT short-term emission limits cannot be based on 
individual stack test results alone in this instance.

    Comment 12: The commenter suggests that EPA should disapprove the 
short-term NOX emission limit of 120 ppm at Texas Eastern 
Perulack because the limit is too high. The commenter cites stack test 
results in which the applicable source was able to maintain a 
NOX emission rate of 66.5 ppm with the highest run being 
67.5 ppm. The commenter demands that EPA send the RACT determination 
back to the state for a re-evaluation showing the lowest achievable 
emission limit for the source.
    Response 12: EPA continues to find that Pennsylvania's RACT 
determination for the General Electric Frame 5 turbine at Texas Eastern 
Perulack (Source ID 037) is reasonable given the analysis of 
technological and economic feasibility, which is part of the record for 
this docket, and that the short-term NOX emission limit of 
120 ppm for these turbines is appropriate. As part of the case-by-case 
NOX RACT analysis, the facility evaluated the technical and, 
where appropriate, economic feasibility of available control strategies 
for the General Electric Frame 5 turbine and determined that there were 
no reasonably available control technologies that were technically or

    Comment 13: The commenter suggests that EPA should disapprove the 
short-term NOX emission limit of 120 ppm at Texas Eastern 
Shermans Dale because the limit is too high. The commenter cites stack 
test results in which the applicable sources were able to maintain a 
NOX emission rate of no greater than 94.8 ppm and 107.7 ppm, 
respectively. The commenter demands that EPA disapprove the RACT 
determination and send it back to the state for a re-evaluation showing 
the lowest achievable emission limit for the sources.
    Response 13: EPA continues to find that Pennsylvania's RACT

    Comment 14: The commenter asks EPA to clarify the potential to emit 
(PTE) supporting documentation for Texas Eastern Shermans Dale, citing 
footers for Tables A-1 and A-2 of Attachment 4 of the source's 
application, which cite a different Texas Eastern compressor station 
(Bernville). The commenter further states that the tables are identical 
to those included with the RACT determination for Texas Eastern 
Bernville. The commenter asks EPA to supplement the record with the 
correct PTE in order to properly determine cost effectiveness and RACT 
for the sources at Texas Eastern Shermans Dale.
    Response 14: EPA acknowledges that Table A-1 in Attachment 4 of the 
facility's RACT II proposal (submitted by Trinity Consultants), which 
is included in the record for this docket, contains a footer that 
mistakenly references the Texas Eastern Bernville facility, not the 
Texas Eastern Shermans Dale facility. Table A-1 in the Shermans Dale 
supporting documentation provides the ``Hourly and Annual Emission 
Estimates'' for the gas-fired General Electric turbine, model M5241. As 
the commenter noted, Table A-1 in Attachment 4 in the RACT II Proposal 
for the Bernville station contains the same information as in Table A-1 
for the Shermans Dale station. This is accurate and appropriate since 
both tables provide emission estimates for the same type of General 
Electric M5241 model turbine, which is used at each facility. 
Therefore, the mistaken reference in Table A-1 in the Shermans Dale 
proposal is just a typographical error and the PTE data is correct. 
There is no need to supplement the record. Finally, EPA disagrees with 
the commenter regarding Table A-2 in Attachment 4. The footer 
associated with Table A-2 properly references the Texas Eastern 
Shermans Dale facility.
    Comment 15: The commenter states that the presses, which vent 
within the building, and the autoclaves should be evaluated for RACT at 
Boeing. The commenter references statements in Boeing's RACT analysis 
that allegedly state that it is seeking a case-by-case RACT for the 
autoclaves and disagrees with Boeing's alleged claim that only the 
autoclaves are subject to case-by-case RACT because no odors from the 
presses have been detected by the workers.
    Response 15: While the commenter's concern addresses the autoclaves 
and presses at the Boeing facility, it is important to note that in the 
present action, EPA is only approving the case-by-case RACT 
determination for Source ID 251, which is a Composite Manufacturing 
Area. It is the only emission unit for which Boeing has requested such 
a source-specific determination and the only case-by-case RACT 
determination for this facility made by PADEP. There is no request for 
a case-by-case RACT determination for the autoclaves or the presses. 
The autoclaves are subject to RACT pursuant to 25 Pa. Code 
129.97(c)(3).
    Comment 16: The commenter stated that an improper economic 
feasibility analysis was conducted for Exelon because a 10% interest 
rate rather than the recommended 3% to 7% interest rate was used.
    Response 16: The current economic feasibility analysis produces 
cost per ton calculations over $21,000/ton of pollutant removed. The 
interest rate is one factor in a complex, multi-factor cost analysis. A 
change in interest rate from 10% to 3%-7% would not reduce the cost per 
ton figure sufficiently to make add-on controls economically feasible 
for the Exelon boilers. The RACT requirement for the two boilers at 
Exelon when burning landfill gas (LFG) is 0.1 lbs NOX/MMBtu, 
which is comparable to Pennsylvania's presumptive RACT requirements 
when burning natural gas, and the operation of a continuous emissions 
monitoring system (CEMS). Therefore, although EPA agrees with the 
commenter about the suitability of the interest rate used in the 
analysis, a lower interest rate does not change the final conclusions 
of the analysis and EPA is finalizing the proposed RACT requirements 
for Exelon.
    Comment 17: The commenter stated that the generic recordkeeping 
provisions of 25 Pa. Code 129.100 are insufficient for Exelon. The 
commenter states that the records must include sufficient data and 
calculations to demonstrate that the requirements of 25 Pa. Code 
129.96-129.99, as applicable, are met. Specifically, the commenter 
referred to EPA's response to the final approval of the Pennsylvania 
rule, which stated that 129.99(d)(6) requires sources to include such 
methods for demonstrating compliance and that EPA would evaluate these 
when they are submitted for SIP approval.
    Response 17: EPA reviewed and evaluated the specific compliance 
demonstration provisions imposed by PADEP for the Exelon case-by-case 
RACT determination under 129.99(d)(6). Specific monitoring and 
recordkeeping provisions are contained in both the Exelon RACT I and 
RACT II permits that are incorporated or will be incorporated into the 
SIP.\26\ For example, both permits require a CEMS, which monitors and 
records the required emissions information on a continuous basis. More 
specific recordkeeping requirements on fuel usage are also contained 
and will be retained in the SIP via the incorporated RACT I permit.

    Comment 18: The commenter stated that EPA and PADEP did not 
consider burner replacement as a control option for Exelon and claims 
that dual-fuel fired (vs. single-fuel fired) burners should have 
specifically been considered as a technically and economically feasible 
option.
    Response 18: EPA continues to find that Pennsylvania's RACT 
determination for the boilers (Source IDs 044 and 045) at Exelon--
Fairless Hills is reasonable given the technological and economic 
feasibility analysis required by 25 Pa. Code Sections 129.92 and 
129.99. Through the RACT analysis, PADEP reviewed the available control 
options with a reasonable potential for application at the sources and 
determined that the short-term NOX emission limit of 0.10 
lb/MMBtu for these boilers when burning LFG is the appropriate RACT 
requirement. The case-by-case RACT determination for these boilers is 
only required when they are burning LFG. The sources must comply with 
Pennsylvania's presumptive RACT II requirements at 25 Pa. Code 
129.97(g)(1), respectively, when burning natural gas or No. 4 residual 
oil. With the use of low NOX burners (LNBs),

[[Page 65714]]

Exelon achieves a RACT NOX emission rate when burning LFG 
equivalent to the NOX emission rate in Pennsylvania's 
presumptive RACT requirements applicable to burning natural gas.
    Comment 19: The commenter claims that without knowing the exit flue 
gas temperature, it is not possible to discount selective non-catalytic 
reduction (SNCR) as an option for the boilers at Exelon and that SNCR 
should not have been discounted as a feasible option for the boilers.
    Response 19: As described in the supporting documentation for 
Exelon's RACT determination, which is part of the record for this 
docket, SNCR was determined to be technically infeasible when burning 
LFG for several reasons, including the high exhaust temperatures 
required by SNCR. Burning LFG naturally reduces combustion 
temperatures, and this lower combustion temperature reduces 
NOX conversions when using SNCR, making the control 
technology less effective for this use. Further, EPA has not identified 
any application of SNCR to boilers when burning LFG. When using natural 
gas or No. 4 residual oil, these Exelon boilers will be required to 
meet the presumptive RACT requirements at 25 Pa. Code 129.97(g)(1)(i) 
and (ii), respectively.
    Comment 20: The commenter stated that EPA has numerous guidance 
policies requiring short-term limits for RACT and has informed PADEP of 
these policies. Therefore, the commenter claims that an annual 
emissions cap for First Quality Tissue as RACT is insufficient.
    Response 20: See Response 3, of this preamble, for a discussion of 
EPA policy on RACT and short-term limits. As explained there, the 
establishment of case-by-case RACT requirements to reduce VOC and/or 
NOX emissions considers not only numeric emission limits, 
but also design and equipment specifications, operational and 
throughput constraints and work practice standards. Each of these 
requirements can take different forms depending on the types of 
processes and emissions at a facility.
    For the First Quality Tissue emission units subject to case-by-case 
RACT, PADEP's RACT determination includes numerous continuous limits on 
the VOC content and usage rate of materials used at the facility. For 
example, materials used in the Adhesive Operation (Source ID 108) are 
restricted in VOC Content and usage rate as follows: Laminating Glue--
0.0005 lb/gal per 4,000 gallons per day (gpd); Transfer Glue--0.010 lb/
gal per 300 gpd; and Core Glue--0.008 lb/gal per 700 gpd.\27\ In 
addition to these continuous limits, PADEP also included in its RACT II 
permit annual VOC limits for various units. These annual limits are 
existing legal requirements at the facility. Because Pennsylvania 
analyzed what should be RACT under operating conditions that included 
annual limits from the First Quality Tissue permit, and PADEP included 
those requirements in its SIP submittal to us, EPA is incorporating 
those annual emission limits into the SIP not as RACT control limits 
but for the purpose of SIP strengthening. For these reasons, we 
consider the annual limits to be separate from RACT and believe the 
commenter's assertion is misplaced.
---------------------------------------------------------------------------

    \27\ See, for example, First Quality Tissue's redacted Permit 
No. 18-00030, Section D., Source ID P102, I. Condition #003; Source 
ID P103, I. Conditions #001 and #003; Source ID P106, I. Condition 
#001; Source ID P108, VI. Condition #004; and Source ID P110, VI. 
Condition #006, which will be incorporated by reference into the SIP 
and is part of the record for this docket.
---------------------------------------------------------------------------

    In preparing the response to this comment, EPA noticed that the 
First Quality Tissue RACT II permit was improperly redacted in that it 
did not contain all of the requirements imposed by PADEP's RACT 
determination. Additional RACT provisions located in the First Quality 
Tissue Permit No. 18099939, Section C, Conditions #007, 026, 027 and 
028 were erroneously redacted. Through a May 27, 2020 email from Mr. 
Viren Trivedi, PADEP, to Ms. Cristina Fernandez, EPA, PADEP has now 
corrected the First Quality Tissue RACT II permit to include these 
provisions and this corrected version will be incorporated into the 
Pennsylvania SIP. The corrected RACT II permit has been added to the 
docket of this rulemaking.
    Comment 21: Two commenters state that EPA should not allow for the 
consideration of plant shutdown as part of the economic feasibility 
analysis for JW Aluminum. They claim that eliminating such 
consideration would likely make a number of control technologies 
economically feasible at Mills 1 and/or 2. The commenters conclude that 
EPA should disapprove the permit and require JW Aluminum to recalculate 
the costs of installing pollution control devices without considering 
shutdown.
    One of the commenters also states that the economic feasibility 
analysis for JW Aluminum improperly included state taxes, property 
taxes, duties, value added tax (VAT), plant shutdown, and inflated 
interest rates. The commenter concludes that EPA should disapprove the 
permit and require JW Aluminum to recalculate the costs of installing 
pollution control devices without these improper factors.
    One commenter states that the use of 12% interest rate in the JW 
Aluminum cost analysis does not reflect current Fed Funds interest 
rates, which are available from https://www.federalreserve.gov/monetarypolicy/openmarket.htm, and now vary between 0 and 0.25%. 
Furthermore, the commenter states that EPA's guidance indicates it is 
feasible to use 3-7% interest rates where firm-specific rates or prime 
rates are not available. However, the commenter further summarizes that 
the EPA guidance also states that the 3% to 7% interest is not 
appropriate when assessing private costs by firms making investments. 
Without making these changes, EPA should return the permit to PADEP and 
require a recalculation of costs for the JW Aluminum RACT analysis.
    Response 21: EPA agrees with the commenter that the values used for 
certain factors such as interest rate, taxes, and plant shutdown in the 
cost analysis may not have been justified in this case. These values 
are among many other values used in a complex, multi-factor cost 
analysis. However, even with adjustments to address questionable 
interest rates, taxes, and plant shutdown, the lowest cost/ton numbers 
to reduce emissions from these sources are still more than $7,600/ton, 
a level that does not change the conclusion about the economic 
feasibility of controls for the rolling mills. Therefore, although EPA 
agrees with the commenter that the values used for certain factors in 
the economic feasibility analysis may not have been appropriate, the 
adjustment of such factors does not change the conclusions of the 
analysis.
    Comment 22: The commenter states that the generic recordkeeping 
provisions of 25 Pa. Code 129.100 are insufficient for Cherokee. The 
commenter states that the records must include sufficient data and 
calculations to demonstrate that the requirements of 25 Pa. Code 
129.96-129.99 are met. Specifically, the commenter referred to EPA's 
response to the final approval of the Pennsylvania rule, which stated 
that 25 Pa. Code 129.99(d)(6) requires sources to include such methods 
for demonstrating compliance and that EPA would evaluate these when 
they are submitted for SIP approval.
    Response 22: EPA reviewed and evaluated the specific compliance 
determination provisions imposed by PADEP for the Cherokee case-by-case 
RACT determination under 129.99(d)(6). There are specific recordkeeping

[[Page 65715]]

provisions for Source ID 101 in Cherokee's. The records needed to 
support the calculations necessary to verify compliance with the VOC 
emission limitation may include emissions data and information on 
emission modeling method and emission factors.\28\
---------------------------------------------------------------------------

    \28\ See Cherokee's redacted RACT Permit No. 49-00007, Section 
D. Source ID 101, IV. Condition #004, which will be incorporated 
into the SIP with this rulemaking and is part of the record in this 
docket.
---------------------------------------------------------------------------

    Comment 23: The commenter states that EPA must require that the 95% 
reduction from NESHAP subpart GGG is RACT for Cherokee because the 
annual emission cap alone is not sufficient for RACT purposes. The 
commenter further states that an annual emissions cap is not sufficient 
as EPA guidance and instruction to Pennsylvania has previously stated 
that RACT should consist of short-term limits such as daily averages.
    Response 23: See Response 3, of this preamble, for a discussion of 
EPA policy on RACT and short-term limits. As explained in that 
response, the establishment of case-by-case RACT requirements to reduce 
VOC and/or NOX emissions under EPA policy considers not only 
numeric emission limits, but also design and equipment specifications, 
operational and throughput constraints, and work practice standards. 
Each of these requirements can take different forms depending on the 
types of processes and emissions at a facility.
    Cherokee's Source 101 is a collection of covered and uncovered 
tanks in the wastewater treatment plant and is already required to 
comply with 40 CFR part 63 subpart GGG, including the 95% reduction 
requirement. The 95% reduction requirement applies to all components of 
Source 101 and has reduced the potential VOC emissions from this source 
from 146 tpy to 15 tpy. Compliance with the 95% reduction requirement 
of subpart GGG and the VOC emissions limit of 15 tpy are existing legal 
requirements for this source.\29\
---------------------------------------------------------------------------

    \29\ See Cherokee title V Permit No. 49-00007, Section D., 
Source ID 101, I. Condition #01 and VII. Condition #013, which is 
part of the record for this docket.
---------------------------------------------------------------------------

    As part of the case-by-case RACT analysis required under 25 Pa. 
Code 129.99, the facility evaluated the technical and, where 
appropriate, economic feasibility of available controls on the various 
individual components of Source 101. Tank covers were found to be 
feasible for certain tanks and are now RACT requirements; however, 
covers were found to be technically or economically infeasible for 
certain other tanks. PADEP's RACT determination for Source 101 also 
requires that biodegradation is maximized, which requires ambient 
exposure of volatiles, which in turn precludes the use of a tank cover 
in certain cases because the processes require tank access for mixing 
and aeration. Having concluded through the RACT evaluation process that 
the type of control options available for certain tanks (upon which 
short-term limits could be imposed) were not technically or 
economically feasible, PADEP imposed good operating practices along 
with the requirement to e.g., to maximize biodegradation of volatiles. 
Overall, RACT for Source 101 includes tank covers, maximization of 
biodegradation, and good operating practices.\30\
---------------------------------------------------------------------------

    \30\ See Cherokee redacted Permit No. 49-00007, Section D., 
Source ID 101, VI. Conditions #010 and #011 and VII. Condition #014, 
which is part of the record for this docket and will be incorporated 
by reference into the SIP. See also, footnote 28 of this preamble.
---------------------------------------------------------------------------

    In addition to these RACT requirements, PADEP has also included the 
existing annual VOC emissions cap referenced by the commenter in its 
redacted RACT II permit. Because Pennsylvania analyzed what should be 
RACT under operating conditions that included annual limits from the 
Cherokee permit, and PADEP included those requirements in its SIP 
submittal to us, EPA is incorporating those annual emission limits into 
the SIP not as RACT control limits but for the purpose of SIP 
strengthening. For these reasons, we consider the annual limits to be 
separate from RACT and believe the commenter's assertion is misplaced.
    Comment 24: The commenter states that EPA should disapprove the 
Texas Eastern Bernville case-by-case RACT determination because the 
NOX emission limits proposed for RACT are not the lowest 
achievable emission rates for the subject sources and do not reflect 
their actual emissions. The commenter notes that the NOX 
emission rates for Source 101 and 102 are identified in the 
documentation as 115.75 lbs/hr and 110.29 lbs/hr, respectively, while 
RACT limit being proposed is 120 lb/hr.
    Response 24: Initially, EPA needs to clarify certain information 
referenced by the commenter. The NOX emission rates found in 
the documentation referenced by the commenter were provided by the 
manufacturer. They are generic rates; not measured NOX 
emission rates at the Texas Eastern Bernville sources. Also, RACT for 
Source IDs 101 and 102 is being proposed at 120 ppm at 15% 
O2 and not 120 lbs NOX/hr, as apparently assumed 
by the commenter.
    EPA also continues to find that Pennsylvania's RACT determination 
for the two General Electric Frame 5 turbines at Texas Eastern 
Bernville (Source IDs 101 and 102) are reasonable given the analysis of 
technological and economic feasibility, which is part of the record for 
this docket, and that the short-term NOX emission limit of 
120 ppm for these turbines is appropriate. As part of the case-by-case 
NOX RACT analysis, the facility evaluated the technical and, 
where appropriate, economic feasibility of available control strategies 
for the two General Electric turbines and determined that there were no 
reasonably available control technologies that were technically and 
economically feasible for the conditions at this facility. 
Technological and economic feasibility are how EPA analyzes what is 
RACT for purposes of implementation of the ozone NAAQS--the standard is 
not lowest achievable emission rates, as suggested by the 
commenter.\31\
---------------------------------------------------------------------------

    \31\ See footnote 20 of this preamble.
---------------------------------------------------------------------------

    PADEP imposed, as a RACT II requirement, a short-term 
NOX limit of 120 ppmvd at 15% O2 at 
all times on each turbine. This limit is based on a statistical 
analysis of historical stack test results (for Texas Eastern's entire 
fleet of General Electric Frame 5 turbines in Pennsylvania). The 
analysis showed that lowering the short-term emission rate without the 
availability of any additional feasible controls would present a 
significant compliance risk.\32\ Ultimately, Pennsylvania agreed with 
the facility's evaluation of feasible controls and that case-by-case 
NOX RACT short-term emission limits cannot be based on 
individual stack test results alone in this instance.

    \32\ See letter dated October 24, 2017 from Enbridge to PADEP, 
which is part of the record for this docket.
---------------------------------------------------------------------------

    Comment 25: The commenter states that the compliance date required 
under RACT is January 1, 2017 and claims that approval of the case-by-
case RACT for Texas Eastern Bernville Sources 101 and 102 includes an 
impermissible compliance date extension until January 1, 2024.
    Response 25: The two turbines at issue would generally be subject 
to the presumptive RACT requirements specified in 25 Pa. Code 
129.97(g)(2), but the source has demonstrated that the presumptive RACT 
limits are not in fact economically and technologically achievable for 
these two turbines. Accordingly, the source submitted, PADEP approved, 
and EPA is now

[[Page 65716]]

agreeing that these two turbines will have a source-specific RACT 
determination, and accompanying limits, for purposes of implementation 
of the 1997 and 2008 ozone NAAQS.
    Texas Eastern evaluated the turbines under the source-specific RACT 
provisions as authorized by 25 Pa. Code 129.97(a). Following the case-
by-case requirements of 25 Pa. Code 129.99, Texas Eastern evaluated the 
technical and economic feasibility of installing controls on the Frame 
5 turbines to reduce NOX emissions as required by RACT. 
Texas Eastern determined that there were no technically and 
economically feasible controls to implement on the turbines. PADEP 
reviewed Texas Eastern's RACT II analysis on control measures and 
determined that the RACT II requirements were a continuation of the 
existing RACT I emission limits. PADEP also included in its RACT II 
permit, emission, fuel usage, and operating hour caps that were 
utilized in the economic feasibility analysis. As explained in our 
proposal document and TSD provided in the docket, we agree with PADEP's 
determination. Source IDs 101 and 102 at Texas Eastern's Bernville 
facility are subject to RACT II requirements established through the 
source-specific alternative provisions of 25 Pa. Code 129.99. Those 
requirements currently apply to the turbines through Texas Eastern 
Bernville's title V permit, which is part of the record for this docket 
and was effective on March 16, 2018.\33\ The redacted version of that 
permit includes the RACT requirements and is being incorporated into 
the SIP through this action.

    \33\ See Texas Eastern Bernville's title V permit No. 06-05033, 
Section E., Group No. SG05, Sources 101 and 102, VII.
---------------------------------------------------------------------------

    In the course of its RACT analysis, Texas Eastern determined that 
it would replace these turbines as part of a major modernization 
project on the Texas Eastern pipeline. Texas Eastern indicated that the 
turbines would be replaced with turbine(s) resulting in a reduction of 
the facility's PTE NOX of at least 290 tpy more than the 
presumptive RACT limit. However, because the modernization project 
would be implemented statewide, Texas Eastern indicated that it would 
be a seven-year project with a completion date of January 1, 2024. As 
described by Texas Eastern, the turbine replacements are part of an 
extensive modernization project across multiple facilities in 
Pennsylvania that requires extensive engineering and scheduling 
considerations as the operation of the compressor stations are 
inherently dependent on each other--for example, to maintain 
appropriate line pressures throughout the pipeline.\34\ Accordingly, 
Texas Eastern said that the replacement of the turbines could not occur 
until January 1, 2024, a date that, as commenter notes, exceeds the 
implementation deadline for RACT for purposes of the 1997 and 2008 
ozone NAAQS.

Bernville, PA, prepared by Trinity Consultants, October 2016, which 
is part of the record for this docket.
---------------------------------------------------------------------------

    Because Texas Eastern considered the replacement of these turbines 
by January 1, 2024 in their RACT proposal to PADEP, and PADEP included 
that requirement in their SIP submittal to us, we are approving that 
requirement into the SIP solely for the purposes of SIP strengthening 
to ensure that the conditions utilized in the economic feasibility 
analysis are implemented and enforceable. Because the turbine 
replacement is not a RACT-level requirement for this source, 
commenter's allegation that EPA is improperly extending the RACT 
implementation deadline beyond statutory and regulatory requirements is 
misplaced.
    Comment 26: The commenter states that Texas Eastern Bernville's 
RACT evaluation is improper and should be cost effective. The commenter 
argues that EPA should not grant this RACT permit for Texas Eastern 
Bernville until full and complete environmental studies have been 
conducted and completed on the proposed site as soon as possible.
    Response 26: Texas Eastern Bernville is an existing, not a 
proposed, source. PADEP and EPA have evaluated the subject sources at 
the Bernville facility under the requirements of the RACT regulations, 
which includes an analysis of potential controls for technical and 
economic feasibility.\35\ The RACT analysis does not require an 
environmental study of the site.

    Comment 27: The commenter states that EPA should reevaluate the 
cost analysis for Wood-Mode's lumber drying sources as the analysis of 
the thermal oxidizer inappropriately used a 10% interest rate and 
considered state and property taxes. The commenter suggests that these 
factors may change the feasibility of the thermal oxidizer and 
concludes that EPA should return the permit to PADEP and disapprove the 
current submittal.
    Response 27: Wood-Mode's lumber drying sources (Source ID 154) are 
not being evaluated under the case-by-case RACT provisions and are 
exempt pursuant to 25 Pa. Code 129.97(c)(2). Therefore, they are not 
relevant to the current rulemaking action. Only the hand-wipe staining 
operations (Source IDs 143 and 146) at Wood-Mode are being evaluated 
for case-by-case RACT determinations. The RACT analysis for the hand-
wipe staining operations included an assessment of a thermal oxidizer. 
EPA agrees with the commenter that the values used for certain factors 
such as interest rate and taxes in the cost analysis for these sources 
may not have been justified in this case. However, the economic 
feasibility of the thermal oxidizer for Source IDs 143 and 146, which 
utilize materials with low VOC concentrations, is estimated at over 
$20,000/ton and over $30,000/ton, respectively. Even with adjustments 
to address questionable interest rates and taxes, the cost/ton numbers 
to reduce emissions from these sources remain elevated and do not 
change the conclusion about the economic feasibility of controls for 
the hand-wiped stain sources.
    Comment 28: The commenter states that the newspaper proof of 
publication for Ward is unreadable because of a redaction on the page. 
Because of this, the commenter concludes that proof of publication for 
Ward Manufacturing was not provided and such proof of publication must 
be resubmitted.
    Response 28: The commenter's concerns about an adequate proof of 
publication relate to a redacted version of the proof of publication on 
the first page in the supporting materials for Ward Manufacturing 
(Ward), which is contained in the docket. That page includes a 
partially obscured copy of the newspaper's proof of publication of 
PADEP's notice of its RACT determination for Ward. However, the second 
page of the supporting materials for Ward contains a second view of the 
proof of publication along with the full version of the actual 
newspaper notice. For these reasons, EPA reasonably determined that 
PADEP had met its obligation to provide proof of publication of its 
public notice for Ward.
    Comment 29: The commenter states that Source 149A at Ward 
Manufacturing did not go through a RACT analysis as required and, 
instead, is inappropriately permitted to comply with 129.97. The 
commenter argues that Source 149A has a PTE of 5 tpy and is ineligible 
for the presumptive RACT requirements of 25 Pa. Code 129.97(c)(2).
    Response 29: Source 149A, which is a grouping of individual 
emission units

[[Page 65717]]

(coring machines), is subject to the presumptive RACT requirements at 
25 Pa. Code 129.97(c)(2) due to enforceable permit conditions that 
limit the potential VOC emissions for each coring machine source in 
this overall grouping.\36\ The Pennsylvania regulations at 25 Pa. Code 
121.1 define potential emissions as ``[t]he maximum capacity of a 
source to emit a pollutant under its physical and operational design. 
Any physical or operational limitation on the capacity of the source to 
emit a pollutant, including air pollution control equipment and 
limitations on hours of operation or on the type or amount of material 
combusted, stored or processed shall be treated as part of the design 
if the limitation or the effect it would have on emissions is Federally 
enforceable or legally and practicably enforceable by an operating 
permit condition. The term does not include secondary emission from an 
offsite facility.'' Therefore, with an enforceable emissions limitation 
on each individual emission unit within the grouping under Source 149A, 
no case-by-case RACT analysis is required for this source. Source 149A 
meets the presumptive RACT applicability at 25 Pa. Code 129.97(c)(2) 
based on using lower VOC content coatings that allow these emission 
units to meet their potential to emit emission caps.

    Comment 30: The commenter questions EPA's approval of annual RACT 
limits for Resilite. The commenter asserts that EPA's guidance requires 
shorter term RACT limits with no greater than 30-day rolling averages.
    Response 30: As explained in response to Comment 3, of this 
preamble, the establishment of case-by-case RACT requirements to reduce 
VOC and/or NOX emissions considers not only numeric emission 
limits, but also design and equipment specifications, operational and 
throughput constraints and work practice standards. Each of these 
requirements can take different forms depending on the types of 
processes and emissions at a facility. For example, emission controls 
can include material content limits or emission limits. Short-term 
emission limits are typically expressed as lb/hr or lb/day limits. VOC 
material content limits, on the other hand, are typically expressed as 
lb/gal material used and are considered continuous controls in that 
they ensure that there is continuous VOC reduction by limiting the 
types of materials that can be used. Similarly, operational or 
throughput constraints are continuous controls on VOC/NOX 
emissions. Therefore, these forms of controls are all considered 
suitable RACT requirements. Each source is different and not every form 
of an emission control is economically or technically feasible for 
every source. In some cases, one or more of the various forms of short-
term emission limits may be infeasible based on an evaluation of the 
RACT-subject facility.
    Source IDs 106, 201, and 202 at Resilite are subject to the case-
by-case RACT analysis prescribed by 25 Pa. Code 129.99. As part of the 
case-by-case NOX RACT analysis, the facility evaluated the 
technical and, where appropriate, economic feasibility of available 
controls. A material change of solvent blends was determined to be 
technically and economically feasible as RACT with new, lower lb/gal 
material limits. Through the current RACT analysis, the RACT I VOC 
limit of 6.83 lbs/gal (minus water) for mat coating material was 
reduced to 4.97 lbs/gal.\37\ It should also be noted that the adhesives 
or sealants applied at Source 106 are now limited to 2.1 lb/gal per 25 
Pa. Code 129.77, not the RACT I limit of 5.98 lbs/gal.\38\ In addition, 
PADEP is also retaining as RACT requirements work practices such as 
limiting what equipment can be cleaned with VOC-containing materials 
and restrictions on how spray guns are cleaned that were established as 
part of RACT I.\39\

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

    PADEP also established annual emission limits for each source that 
are derived from the VOC-content of the materials used at that source. 
In doing so, PADEP eliminated a former annual emissions cap for the 
facility. Because Pennsylvania developed annual limits for the Resilite 
permit, and PADEP included those requirements in its SIP submittal to 
us, EPA is incorporating those annual emission limits into the SIP not 
as RACT control limits but for the purpose of SIP strengthening. For 
these reasons, we consider the annual limits to be separate from RACT 
and believe the commenter's assertion is misplaced.
    Comment 31: The commenter questions the assumed capture efficiency 
for the molding process in Foam Fabricator's cost effectiveness 
analysis. The commenter asserts that the cost effectiveness of controls 
on the molding operations should be reevaluated with updated capture 
efficiency to find controls effective.
    Response 31: PADEP and EPA evaluated the sources at Foam 
Fabricators subject to the RACT case-by-case requirements set forth in 
25 Pa. Code 129.99. The RACT analysis determined that the three 
technically feasible control scenarios for the molding operations were 
economically infeasible, with the cost to remove VOCs ranging from 
$15,702/ton to $23,699/ton.\40\ Capture efficiency is one factor in a 
complex, multi-factor cost analysis. EPA has examined PADEP's cost 
effectiveness analysis and finds that an updated evaluation with an 
increased capture efficiency would not impact the cost analysis enough 
to change the RACT determination.

IV. Final Action

    EPA is approving case-by-case RACT determinations for 19 sources in 
Pennsylvania, as required to meet obligations pursuant to the 1997 and 
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 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of source-
specific RACT determinations under the 1997 and 2008 8-hour ozone NAAQS 
for certain major sources of VOC and NOX in Pennsylvania. 
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

[[Page 65718]]

incorporated by reference in the next update to the SIP 
compilation.\41\

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. 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 15, 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 Pennsylvania's NOX and VOC 
RACT requirements for 19 case-by-case facilities for the 1997 and 2008 
8-hour ozone NAAQS may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
