Air Plan Approval; Florida; Revision of Excess Emissions 
Provisions and Emission Standards; Amendments to Stationary Sources--
Emission Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving State 
Implementation Plan (SIP) revisions submitted by the State of Florida 
on November 22, 2016, and supplemented on September 30, 2022, through 
the Florida Department of Environmental Protection (FDEP). The November 
22, 2016, SIP revision is in response to EPA's SIP Call published on 
June 12, 2015, concerning excess emissions during startup, shutdown, 
and malfunction (SSM) events. The September 30, 2022, supplemental SIP 
revision addresses additional SSM-related rule amendments identified by 
the State and the addition of source specific sulfur dioxide 
(SO2) and nitrogen oxide (NOX) emission limits. 
EPA is approving these SIP revisions and finds that they correct the 
deficiencies identified in the June 12, 2015, SIP Call. EPA is also 
approving a portion of a SIP revision submitted by FDEP on April 1, 
2022, which modifies provisions that regulate emissions of 
SO2, NOX, and visible emissions and modifies 
requirements for major stationary sources of volatile organic compounds 
(VOC) and NOX.

DATES: This rule is effective September 5, 2023.

SUPPLEMENTARY INFORMATION: 

I. Background

a. Florida's November 22, 2016, and September 30, 2022, SIP Submissions

    On November 22, 2016, FDEP submitted a revision to the Florida SIP 
(referred to hereinafter as Florida's ``Excess Emissions Rule SIP 
Revision'') in response to EPA's June 12, 2015, action titled ``State 
Implementation Plans: Response to Petition for Rulemaking; Restatement 
and Update of EPA's SSM Policy Applicable to SIPs; Findings of 
Substantial Inadequacy; and SIP Calls to Amend Provisions Applying to 
Excess Emissions During Periods of Startup, Shutdown, and Malfunction'' 
(``2015 SSM SIP Action''). See 80 FR 33839 (June 12, 2015). In the 
Excess Emissions Rule SIP Revision, FDEP requests EPA approval of the 
following changes to the Florida SIP: (1) Removal of Florida 
Administrative Code Rule (referred to hereinafter referred as ``Rule'') 
62-210.700(4) with the addition of equivalent language to Rules 62-
210.700(1) and (2); (2) amendment of Rule 62-210.700(3) to revise the 
particulate matter (PM) limits applicable during boiler cleaning (soot 
blowing) and load changes by removing the statement that excess 
emissions during these periods ``shall be permitted,'' removing the 
exemption for pollutants other than PM and visible emissions, and 
removing a specific allowance for visible emissions which exceed 60 
percent opacity for up to four six-minute periods during the 3-hour 
period of excess emissions allowed for soot blowing or load change; (3) 
addition of Rule 62-210.700(6), which states that Rules 62-210.700(1) 
and (2) shall not apply after May 22, 2018, to either category-specific 
or unit-specific limits that have been incorporated into Florida's SIP; 
and (4) addition of Rule 62-210.700(7), which states that after the 
State's effective date of the rule change (October 23, 2016), Rules 62-
210.700(1) and (2) shall not apply to new permit-specific emission 
limits established pursuant to Florida's Prevention of Significant 
Deterioration (PSD) and Nonattainment New Source Review (NNSR) 
regulations (Rules 62-212.400 and 62-210.500). The Excess Emissions 
Rule SIP revision includes information demonstrating that these changes 
will not interfere with any applicable requirement concerning 
attainment of any National Ambient Air Quality Standards (NAAQS) and 
reasonable further progress (RFP), or with any other applicable 
requirement of the Clean Air Act (CAA or Act).
    On September 30, 2022, FDEP submitted a supplemental revision 
(referred to hereinafter as Florida's ``Supplemental SSM SIP 
Revision'') to the State's November 22, 2016, Excess Emissions Rule SIP 
Revision. In the Supplemental SSM SIP Revision, FDEP includes 
alternative SIP emission limits for those SIP emission limits that it 
identified as ``problematic'' if applied continuously and several 
changes to language throughout Chapter 62-296. The State requests EPA 
approval of the following changes: (1) Amendment of existing Rule 62-
296.405, ``Fossil Fuel Steam Generators with More Than 250 Million Btu 
Per Hour Heat Input,'' and Rule 62-296.570, ``Reasonably Available 
Control Technology (RACT)--Requirements for Major VOC- and 
NOX-Emitting Facilities,'' to clarify how emissions are 
calculated, including during periods of startup, shutdown, and 
malfunction; (2) addition of emissions-unit-specific SO2 and 
NOX emission limits for certain sulfuric acid plants (SAPs) 
and nitric acid plants (NAPs) in Florida; (3) removal of SO2 
emission limits in Rule 62-296.402, ``Sulfuric Acid Plants''; and (4) 
removal of NOX emission limits in Rule 62-296.408, ``Nitric 
Acid Plants.'' The

[[Page 51703]]

Supplemental SSM SIP revision includes technical support materials to 
demonstrate that these changes will not interfere with any applicable 
requirement concerning attainment of any NAAQS and RFP, or with any 
other applicable requirement of the Act.
    On May 8, 2023, EPA proposed to approve FDEP's November 22, 2016, 
and September 30, 2022, SIP revisions. See 88 FR 29598. That notice of 
proposed rulemaking (NPRM) is titled ``Air Plan Approval; Florida; 
Revision of Excess Emissions Provisions and Emission Standards'' 
(Excess Emissions Proposal). In the Excess Emissions Proposal, EPA also 
proposed to determine that the SIP revisions correct the deficiencies 
that the Agency identified in the 2015 SSM SIP Action with respect to 
Florida. The reasons for the proposed approval and determination are 
stated in the Excess Emissions Proposal and will not be restated here. 
The public comment period for EPA's proposed approval and determination 
ended on June 7, 2023. EPA received one favorable comment and one set 
of comments in a joint letter submitted by the Sierra Club and the 
Environmental Integrity Project (hereinafter collectively referred to 
as the Commenters) which agree in part and disagree in part with EPA's 
proposed action. Both sets of comments are available in Docket No. EPA-
R04-OAR-2022-0892.

b. Florida's April 1, 2022, SIP Submission

    On April 1, 2022, FDEP submitted a SIP revision seeking to revise 
Rules 62-296.405, ``Fossil Fuel Steam Generators with More Than 250 
Million Btu Per Hour Heat Input,'' and 62-296.570, ``Reasonably 
Available Control Technology (RACT)--Requirements for Major VOC- and 
NOX- Emitting Facilities.'' 1 2 Florida's April 
1, 2022, SIP revision includes technical support materials to 
demonstrate that the changes and deletions to these rules will not 
interfere with any applicable requirement concerning attainment of any 
NAAQS and RFP, or with any other applicable requirement of the Act.
---------------------------------------------------------------------------

    \1\ On March 30, 2023, Florida submitted a letter to EPA 
withdrawing the removal of Rule 62-296.405(1)(c)1.g. and 62-
296.405(1)(d)2., from EPA's consideration. For this reason, EPA is 
not acting on the removal of (1)(c)1.g. and (1)(d)2 described in the 
April 1, 2022, SIP revision. The letter is available in the docket 
for this rulemaking.
    \2\ The April 1, 2022, submittal transmits several changes to 
other Florida SIP-approved rules. These changes are not addressed in 
this rulemaking and will be considered by EPA in a separate 
rulemaking.
---------------------------------------------------------------------------

    Specifically, the April 1, 2022, submission contains changes to the 
following provisions in Rule 62-296.405: 62-296.405(1)(a); 62-
296.405(1)(c)1.; 62-296.405(1)(c)1.b. through e.; 62-296.405(1)(c)1.h. 
through i.; 62-296.405(1)(c)2.a., b., and d.; 62-296.405(1)(c)3.; 62-
296.405(1)(d)3.; 62-296.405(1)(e); and 62-296.405(2). These provisions 
regulate emissions of SO2, NOX, and visible 
emissions from certain fossil fuel-fired steam generators with more 
than 250 million British thermal units (Btu) per hour heat input. The 
changes to these provisions revise a visible emissions limitation and 
clarify to whom the results of visible emissions testing must be 
submitted. The changes also remove outdated language, including 
emission limits for sources that have shut down or have more stringent 
federally enforceable limits, add specific citations for EPA test 
methods, and make minor wording edits. These changes do not allow for 
any pollutant emission increases because they only (1) remove certain 
SIP rules that are either obsolete or that are redundant for units that 
have more stringent federally enforceable limits in the SIP and (2) 
revise other rules in a way that would not interfere with any 
applicable requirement concerning attainment, RFP, or any other 
applicable requirement of the CAA.
    The April 1, 2022, submission also removes obsolete provisions in 
Rule 62-296-570, ``Reasonably Available Control Technology (RACT)--
Requirements for Major VOC- and NOX-Emitting Facilities'' 
and makes changes to clarify the intent of the Rule and update certain 
cross-references. FDEP developed Rule 62-296.570 to implement VOC and 
NOX RACT for existing major sources of VOC and 
NOX in its then moderate ozone nonattainment area--the South 
Florida Area (consisting of Broward, Dade, and Palm Beach Counties)--as 
required by CAA section 182.\3\ After EPA redesignated the South 
Florida Area to attainment, Florida revised its RACT rules such that 
Rule 62-296.570 now applies to the South Florida maintenance area.\4\ 
EPA has evaluated the State's non-interference demonstration and finds 
that the changes to Rule 62-296.570 would not interfere with any 
applicable requirement concerning attainment of any NAAQS and RFP, or 
any other applicable requirement of the CAA.
---------------------------------------------------------------------------

    \3\ See 60 FR 2688, 2689 (January 11, 1995) (approving Florida's 
January 8, 1993, SIP revision and noting that Florida's RACT rule 
``applies to the 1990 Clean Air Act Amendment requirement for RACT 
for existing major sources of VOCs and NOX in Florida's 
moderate non-attainment area.''). The fact that Rule 62-296.570 
applies solely to existing units is further evidenced by language in 
Florida's January 8, 1993, SIP revision (available in the docket for 
this rulemaking), the May 31, 1995, compliance date in Rule 62-
296.570(4)(a)1, and the exclusion of new and modified major VOC- and 
NOX emitting facilities subject to major new source 
review through Rule 62-296.570(1)(a) (referencing Rule 62-
296.500(1)(b)).
    \4\ See 60 FR 10325 (February 24, 1995) (redesignating the South 
Florida Area to attainment); 64 FR 32346 (June 16, 1999).
---------------------------------------------------------------------------

    In a NPRM published on May 8, 2023, EPA proposed to approve the 
portion of Florida's April 1, 2022, SIP revision seeking to amend Rules 
62-296.405 and 62-296.570. See 88 FR 29591. That notice of proposed 
rulemaking is titled ``Air Plan Approval; Florida; Amendments to 
Stationary Sources--Emission Standards'' (Emission Standards Proposal). 
Comments on the Emission Standards Proposal were due on or before June 
7, 2023. EPA received no comments on the Emission Standards Proposal.

II. Response to Comments

    This section contains summaries of the comments received and EPA's 
responses.
    Comment 1: Regarding the removal of SO2 and 
NOX emission limits from Rules 62-296.402, ``Sulfuric Acid 
Plants,'' and 62-296.408, ``Nitric Acid Plants,'' respectively, 
Commenters state that ``EPA posits that a longer-term limit will 
protect the 1-hour SO2 NAAQs if it is of comparable 
stringency to a maximum 1-hour NAAQS-protective `critical emission 
value' that provides for attainment.'' \5\ Commenters then note that 
EPA's 2014 SO2 Nonattainment Guidance (SO2 
Nonattainment Guidance) \6\ sets out a method that uses an 
``equivalency ratio'' derived by compiling a representative 
distribution, or sample set, of actual emissions data on a 1-hour 
average to compute a distribution of longer-term emission averages and 
then a ratio of the 99th percentile of the longer-term values to the 
99th percentile of the hourly values.\7\ Commenters assert that 
Florida's proposed longer-term average limits are based on EPA's 
SO2 Nonattainment Guidance and that ``one obvious problem'' 
with the method is that the equivalency ratio can vary greatly 
depending on the selected data set.\8\ Commenters go on to state that 
EPA has not provided all relevant information about the data set used 
to

[[Page 51704]]

calculate the source-specific limits and it is therefore unclear 
whether the selected data are appropriate and whether they yield 
standards comparable to what might result from other potentially 
representative data.
---------------------------------------------------------------------------

    \5\ Although this statement only appears in the comment 
regarding SO2 limits in Rule 62-296.407, Commenters note 
in their comment regarding NOX limits in Rule 62-296.408 
that they ``have the same concerns . . . as with the SO2 
limits.'' The comments on the NOX limits relate to the 1-
hour NO2 NAAQS.
    \6\ See SO2 Nonattainment Guidance, https://www.epa.gov/sites/production/files/2016-06/documents/20140423guidance_nonattainment_sip.pdf.
    \7\ See supra note 5.
    \8\ Id.
---------------------------------------------------------------------------

    Response 1: Regarding the Commenters' statement that ``EPA posits 
that a longer-term average limit will protect the 1-hour SO2 
NAAQS . . . , '' the Excess Emissions Proposal does not, as the 
statement may suggest, include new policy statements on the use of 
longer-term average limits for NAAQS attainment planning purposes. 
Rather, in the Excess Emissions Proposal, EPA merely summarizes the 
approach for establishing acceptable longer-term average emission 
limits included in the SO2 Nonattainment Guidance. The 
proposal also notes that all areas in Florida that had been through the 
attainment planning and/or designation process had been redesignated 
and, in Sections II.B.5.I. and II.B.5.II., details the methodology that 
Florida employed to determine proposed longer-term average emission 
limits for several sulfuric acid plants (SAPs) and nitric acid plants 
(NAPs) in the State. EPA also specifically highlights the differences 
between the attainment planning approach laid out in the SO2 
Nonattainment Guidance and the assessment made for determining 
comparably stringent limits to replace the existing SIP-rule limits.
    As discussed in the Excess Emissions Proposal, Florida's longer-
term average emission limits for several SAPs and NAPs in the September 
30, 2022, SIP revision are not based entirely on the SO2 
Nonattainment Guidance. As FDEP explains in its SIP submittal, to set 
reasonable longer-term average emission limits that would be comparable 
to the existing SIP-rule emission limits proposed for removal from the 
SIP, the State made use of the statistical principles that EPA applied 
in the SO2 Nonattainment Guidance to calculate equivalency 
ratios. In the Excess Emissions Proposal, EPA states that Florida made 
use of similar statistical approaches to the approach outlined in the 
guidance when developing its source-specific emission limits for 
SO2 and NOX. See 88 FR 29598, 29605-08. Making 
use of a similar statistical analysis of actual emissions data to 
develop longer-term average emission limits that would be comparable to 
existing SIP-rule emission limits and not allow emissions increases is 
not the same as applying the guidance for demonstrating that a 
prospective limit is sufficient to provide for attainment of the NAAQS.
    As noted above, the Excess Emissions Proposal discusses the 
modified methodology for determining the longer-term average emission 
limits that can replace the existing SIP rule SO2 emission 
limits for SAPs and the existing SIP rule NOX emission 
limits for NAPs. The analysis demonstrates that the longer-term average 
emission limits are comparably stringent to those existing SIP emission 
limits and, therefore, do not allow any emissions increases. The 
detailed analysis described in section II.B.5. of the Excess Emissions 
Proposal explains why the longer-term emission limits developed by 
Florida are comparably stringent to the existing SIP limits. The 
proposal also specifically details how Florida's approach in 
establishing longer-term average emission limits for certain SAPs and 
for the two NAPs in the State differed from EPA's approach detailed in 
the SO2 Nonattainment Guidance for the purpose of attainment 
planning, and it highlights the similarities, where relevant, between 
the two approaches. EPA did not state or suggest that Florida made use 
of actual modeled ``critical emission values'' (CEVs) to determine the 
new longer-term average emission limits proposed for incorporation into 
the SIP.
    At the time of proposal, EPA had no information that there were any 
NAAQS issues that would require modeling a new CEV, and no new 
information has been provided to indicate that there would be NAAQS 
compliance issues around any of the facilities subject to this 
rulemaking. Rather, FDEP established new, source-specific emission 
limits and compared them to existing SIP emission limits in Rules 62-
296.402 and 62-296.408. The starting point for the analysis was not a 
nonattainment planning situation, but instead a consideration of any 
potential relaxation to the SIP in replacing the existing SIP-rule 
emission limits with source-specific longer-term average emission 
limits.
    As discussed in the Excess Emissions Proposal, the existing SIP 
emission limits proposed for removal from the SIP were only applicable 
to steady-state periods of operation, having functioned with an 
exemption for periods of SSM. With Florida's removal of exemptions for 
SSM in Rule 62-210.700, ``Excess Emissions,'' in response to the 2015 
SSM SIP Action, the State wanted to develop new, continuous emission 
limits that would apply during all periods of operation. Having been 
through the attainment planning process and air quality designations 
process for several SAPs (i.e., Mosaic Fertilizer's Riverview facility, 
Bartow facility, and New Wales facility), FDEP recognized that several 
SAPs in the State already had existing longer-term average, source-
specific emission limits which were continuous and at least as 
stringent as the emission limits in Rule 62-296.402 (which had not been 
adopted for attainment planning purposes).
    The State then proposed new, longer-term average emission limits 
for the remaining SAPs in the State, Mosaic South Pierce, Nutrien White 
Springs, and Tampa Electric Company (TECO) Polk, which would be based 
on an analysis of comparable stringency to the previously existing 
short-term limits using each source's continuous emissions monitoring 
system (CEMS) data, similar to the longer-term average emission limit 
approach developed in the SO2 Nonattainment Guidance. For 
this analysis, Florida used the existing SIP rule emission limits in 
place of the CEV concept used in the SO2 Guidance to 
demonstrate how much a longer-term average limit should be scaled down 
to compensate for the longer averaging period and maintain the same 
level of emission limit stringency. Similarly, the State developed 
longer-term average continuous emission limits for the two NAPs in the 
State, Ascend Pensacola, and Trademark Nitrogen, which could build off 
of a similar analysis based on historical CEMS data. EPA has not 
suggested that FDEP made use of a modeled CEV for these SAPs and NAPs. 
The existing 3-hour average SIP emission limits were the baseline for 
the longer-term average analysis. See 88 FR 29598, 29605-08.
    EPA disagrees with the Commenters that the Agency did not provide 
enough information to assess the appropriateness of the data sets used 
in the analysis. The Excess Emissions Proposal and associated docket 
provide sufficient relevant information about the data sets Florida 
used to calculate the source-specific limits. The State utilized over 
three years of CEMS data for Mosaic South Pierce, three years of data 
for Nutrien White Springs SAP F, two years of data for Nutrien White 
Springs SAP E, and three years of data for Ascend Pensacola.\9\ The 
data sets used were from the most recently available complete years and 
provide ample data points to perform robust analyses and to reach 
reliable conclusions.
---------------------------------------------------------------------------

    \9\ See ``Nutrien White Springs Eq Ratio 2019-2021,'' ``Mosaic 
SP SO2 Equivalence Ratios,'' and ``Ascend Nitric Acid 
Plant Equivalency Ratio'' in the docket for this rulemaking.
---------------------------------------------------------------------------

    EPA included the CEMS data as provided by FDEP for the Mosaic South 
Pierce SAPs, Nutrien White Springs

[[Page 51705]]

SAPs, and the Ascend Pensacola NAP in the rulemaking docket at the time 
of proposal. EPA also evaluated the analysis that FDEP performed in 
selecting longer-term average emission limits for these facilities. The 
Excess Emissions Proposal describes the use of 99th percentile 1-hour 
average, 3-hour average, 6-hour average, and 24-hour block average 
emissions, as applicable for the SAPs, and the proposed longer-term 
average emission limits being evaluated. Similarly, EPA describes the 
use of the 98th percentile 1-hour average, 3-hour average, and 720-hour 
rolling average emissions for the Ascend Pensacola NAP.
    As discussed in the Excess Emissions Proposal, for the Nutrien 
White Springs and Mosaic South Pierce SAPs, FDEP evaluated the ratio of 
the 24-hour:3-hour average 99th percentile emissions, then also 
considered the ratio of 24-hour:1-hour average 99th percentile 
emissions. FDEP then selected a longer-term average emission limit (840 
lbs/hr) in line with the most conservative (i.e., lowest) equivalency 
ratios determined for Nutrien White Springs and considerably more 
stringent than the calculated equivalency ratios would have determined 
to be appropriate for Mosaic South Pierce. See 88 FR 29598, 29605-09. 
The ratio of the selected emission limit to the existing SIP emission 
limit (917 lbs/hr) is 0.916. The average of the two 24-hr:3-hr ratios 
determined for SAPs E (0.950) and F (0.914), would be 0.932. Therefore, 
the final limit across these two SAPs at Nutrien White Springs is in 
line with the lower end of what the 24-hr:3-hr equivalency ratios would 
indicate is an appropriate longer-term average emission limit and more 
stringent than what an equal consideration for the analysis across both 
SAPs would call for. Regarding Mosaic South Pierce, FDEP and Mosaic 
Fertilizer agreed upon an equivalency ratio of 0.750 for the source, 
which is lower than any of the 24-hr:3-hr or 24-hr:1-hr equivalency 
ratios included in the analysis of the CEMS data. See 88 FR 29598, 
29605.
    Regarding the TECO Polk SAP, with the new 6-hour average emission 
limit, the ratio between the selected limit and the existing SIP 
emission limit is in line with the lowest 6-hr:1-hr ratio from the 
available CEMS data for Nutrien White Springs and Mosaic South Pierce. 
See 88 FR 29598, 29610. For Ascend Pensacola, FDEP considered the ratio 
of the 720-hour:3-hour average 98th percentile emissions, then also 
considered the ratio of the 720-hour:1-hour average 98th percentile 
emissions. The selected emission limit compared to the existing SIP 
emission limit for Ascend Pensacola and Trademark Nitrogen results in a 
significantly more stringent ratio (0.867) than the CEMS data analysis 
would lead to for the 720-hr:3-hr (0.958) and 720-hr:1-hr (0.958) 
ratios. See 88 FR 29598, 29607, 29612-13. The ultimate longer-term 
average emission limits for these SAPs and NAPs were compared to these 
existing SIP emission limits and the ratios of longer-term average 
emissions to shorter-term average emissions in the CEMS data to assess 
the comparability with the existing SIP emission limits and therefore 
assess the potential relaxation to the SIP. FDEP developed its new 
source-specific emission limits in an appropriate way to ensure that 
the SIP is not relaxed and that increased emissions will not occur 
because of the SIP revision.
    As shown in the tables below, and as discussed in the Excess 
Emissions Proposal,\10\ in all cases the maximum emissions 
theoretically allowed under the new source-specific limits are less 
than what is theoretically allowed under the existing SIP limits on 
both a short-term and a long-term (annual) basis.

    Regarding the other impacted SAPs at Mosaic Fertilizer's Riverview 
facility, Bartow facility, and New Wales facility, EPA notes in the 
Excess Emissions Proposal that these facilities already had longer-term 
average continuous emission limits that had been previously approved 
into the SIP to enable attainment of the 2010 SO2 NAAQS.\11\ 
EPA compared these approved source-specific emission limits, which in 
fact provided for attainment in the respective nonattainment areas, to 
the existing SIP emission limit at Rule 62-296.402 (which had not been 
relied upon to show attainment) and determined that these emission 
limits are at least as stringent as the limits provided in Rule 62-
296.402. EPA did not reopen for comment these longer-term average 
limits for these facilities, as noted in the proposal, and the 
Commenters did not raise any issues with these facilities or their 
existing longer-term average source-specific emission limits with any 
specificity. See 88 FR 29598, 29612, 29615. The Excess Emissions 
Proposal refers readers to the actions in which EPA approved those 
source-specific emission limits for more detail on how those limits 
were developed. In that proposal, EPA only compares the new longer-term 
average limits with the existing limits at Rule 62-296.402.
---------------------------------------------------------------------------

    \11\ See 82 FR 30749 (July 3, 2017), 85 FR 9666 (February 20, 
2020).
---------------------------------------------------------------------------

    EPA also reiterates that, for the NAPs, the steady-state SIP 
emission limit was carried forward directly into the source-specific 
permits being approved into the SIP. This means, as EPA described in 
the Excess Emissions Proposal, no effective change to the existing SIP 
emission limitations results from removing the Rule 62-296.408 emission 
limit from the SIP. Instead, the two NAPs each received two new source-
specific emission limits: the first covers the steady-state modes of 
operation and is the same as required by the existing SIP; the second 
applies at all times, including periods of SSM, and is comparably 
stringent to the existing SIP emission limit. Therefore, the SIP is 
strengthened by the changes applicable to these sources.
    Regarding all SAPs, except for the TECO Polk SAP, the New Source 
Performance Standard (NSPS) at 40 CFR part 60, subpart H, Standards of 
Performance for Sulfuric Acid Plants, imposes the same emission limit 
for steady-state periods as the most stringent emission limit in Rule 
62-296.402 (i.e., 4 pounds of SO2 per ton of sulfuric acid 
produced (lb/ton)). Therefore, EPA has several reasons to believe that 
steady-state emissions will not increase subsequent to this revision: 
(1) The new, longer-term average emission limits are comparably 
stringent to the existing steady-state SIP-rule emission limit, (2) the 
longer-term average emission limits significantly reduce the total 
SO2 emissions allowed on a short-term basis and also a long-
term (annual) basis, and (3) the NSPS will still apply to Nutrien White 
Springs and Mosaic South Pierce.
    Comment 2: Commenters state that longer term limits cannot 
guarantee protection of 1-hour standards and generally should not be 
used to protect short-term NAAQS. Additionally, the Commenters state 
that if EPA chooses to allow longer-term emission limits, it should 
ensure that those limits are as protective as possible to ensure that 
the health-based standards are maintained at all times.
    Response 2: EPA disagrees with the Commenters' statement that 
longer-term average limits should not be used to protect short-term 
NAAQS. As discussed in Section II.B.5. of the Excess Emissions 
Proposal, EPA's 2014 SO2 Nonattainment Guidance provides 
procedures for using a statistical analysis to determine NAAQS-
protective longer-term average emission limits for sources with 
variable emissions. In general, EPA believes that when the statistical 
procedure described in the SO2 Nonattainment Guidance is 
applied appropriately, longer-term average limits are comparably 
effective in achieving attainment of a short-term NAAQS in 
nonattainment areas. EPA has approved the application of the longer-
term averaging policy on a case-by-case basis in accordance with the 
concepts recommended in the SO2 Nonattainment Guidance for 
several SO2 nonattainment-area attainment SIPs and 
redesignation requests that require a NAAQS evaluation.\12\ This 
includes attainment-SIP and redesignation-request approvals for 
SO2 nonattainment areas in Florida. Appropriately set 
longer-term average limits can provide for attainment of a short-term 
NAAQS because they are set low enough that they are equally stringent 
as the respective shorter-term limits with higher thresholds.
---------------------------------------------------------------------------

    \12\ EPA analyzed and approved several SO2 attainment 
SIPs and redesignation requests that provided modeled attainment of 
the 2010 short-term standard determining the suitably adjusted long 
term limits can be protective of the expected to 1-hour 
SO2 standard. See, e.g., 87 FR 33095 (June 1, 2022), 85 
FR 9666 (February 20, 2020), 83 FR 25922 (June 5, 2018), 84 FR 30920 
(June 28, 2019), 82 FR 30749 (July 3, 2017).
---------------------------------------------------------------------------

    Florida's application of the statistical analysis procedures 
contained in EPA's SO2 Nonattainment Guidance for this SIP 
action was not for the purpose of demonstrating compliance with the 
short-term 1-hour SO2 and NO2 NAAQS. Rather, 
Florida's analysis shows that replacement of the existing short-term 
SIP-approved limits with the new source-specific longer-term average 
emission limits would not allow for an increase in emissions and 
thereby lessen the stringency of the SIP. As a result, the control 
strategy needed to meet a comparably stringent longer-term emission 
limit would necessarily be as effective as the control strategy needed 
to meet the shorter-term emission limit. Moreover, the statistical 
procedures were used to develop source-specific longer-term average 
emission limits that will apply during all periods of operation and 
that are comparatively

[[Page 51707]]

stringent to the existing shorter-term limits in Florida's SIP for SAPs 
and NAPs, which only apply during full-load operation and exclude SSM 
periods. While Florida's submission is neither intended nor required to 
demonstrate protection of 1-hour standards, such as what would be 
required of an attainment SIP supported by a modeling demonstration, 
Florida used appropriate source-specific data sets and appropriately 
applied statistical procedures to develop longer-term average emission 
limits that are comparatively stringent to the existing SIP emission 
limits such that the SIP revision will not result in emissions 
increases and consequently will not interfere with any applicable 
requirement of the CAA.
    Comment 3: Commenters state that if EPA chooses to allow longer-
term limits to protect short-term NAAQS, the Agency should ensure that 
the conversion factor used to calculate a longer-term limit is 
appropriately low and that the facility would violate its longer-term 
limit if it violated its ``critical emission value.''
    Response 3: EPA believes that the procedures used by Florida to 
calculate the longer-term average limits for the SAPs and NAPs 
discussed in the May 8, 2023, Excess Emissions Proposal are appropriate 
and provide for comparably stringent longer-term average emission 
limits that apply during all periods of operation of the affected 
sources. The procedures used by Florida to derive the longer-term 
average limits are discussed and summarized in Section II.B.5. of the 
Excess Emissions Proposal. As shown in the example calculations 
provided for the Mosaic South Pierce facility and described in the 
Excess Emissions Proposal, Florida used an equivalency ratio of 0.75 to 
establish the 24-hour SO2 limit for the two SAPs, which is 
approximately 23 percent lower than the 0.978 equivalency ratio 
calculated by applying the procedure of the SO2 
Nonattainment Guidance.\13\ Therefore, the 24-hour SO2 
limits established for these SAPs are even more stringent than limits 
that would be derived by strictly following the procedures in the 
SO2 Nonattainment Guidance. Likewise, the longer-term 
average limits for the other SAPs and NAPs subject to this rulemaking 
are at least as stringent as the longer-term average limits that were 
calculated following the procedures of the SO2 Nonattainment 
Guidance.
---------------------------------------------------------------------------

    \13\ See supra note 9.
---------------------------------------------------------------------------

    As discussed in EPA's response to Comment 1, the concept of the 
``critical emission value'' (CEV) is not applicable to the analysis 
Florida performed to calculate the comparably stringent longer-term 
average limits that apply during all periods of operation, including 
SSM events. Florida used the existing 3-hour SIP limits applicable the 
SAPs and NAPs as the starting point for deriving comparably stringent 
longer-term average limits. No CEVs were calculated. To the extent the 
Commenters may be referring to how the longer-term average emission 
limits are established relative to the existing 3-hour average SIP 
emission limits, EPA disagrees that the limits should be set such that 
any exceedance of the existing 3-hour average limits would result in 
exceeding the longer-term average limit. The purpose of setting a 
longer-term average emission limit is to allow for some level of 
emissions variability. Prior to this action, the existing SIP emission 
limits did not apply during periods of SSM, and with this change, a 
comparably stringent emission limit will apply at all times, including 
those periods of SSM. EPA discussed the statistical approach that 
Florida employed in establishing its longer-term average emission 
limits which are comparable to existing SIP emission limits in the 
responses to Comments 1 and 2.
    Comment 4: Commenters state that there appears to be no description 
in EPA's proposed rule or Florida's SIP submission regarding the 
removal of subparagraph 62-296.405(1)(c)3, which provides that owners 
of fossil fuel steam generators shall monitor their emissions and the 
effects of the emissions on ambient concentrations of SO2, 
in a manner, frequency, and locations approved and deemed reasonably 
necessary and ordered by the Department. Commenters question why EPA 
has not included any analysis on how removing this provision would not 
interfere with attainment, reasonable further progress, or any other 
applicable requirement under section 110(l) of the Act.
    Response 4: EPA's May 8, 2023, Excess Emissions Proposal (88 FR 
29598), which addresses Florida's November 22, 2016, and September 30, 
2022, SIP revisions, did not discuss the removal of subparagraph 62-
296.405(1)(c)3 because the Excess Emissions Proposal did not propose to 
remove it from the SIP. See 88 FR at 29602 and 29603, n.15. Instead, 
EPA proposed to remove subparagraph 62-296.405(1)(c)3 from the SIP in a 
different and separate notice of proposed rulemaking also published on 
May 8, 2023--the Emission Standards Proposal (88 FR 29591). In that 
notice, EPA explained the rationale for removal and proposed to find 
that the changes to Rule 62-296.405 would not interfere with any 
requirement concerning attainment and RFP, or any other applicable 
requirement of the CAA. See 88 FR 29591, 29593-94. EPA did not receive 
any comments on the Emission Standards Proposal and is finalizing 
action on both the Emission Standards Proposal and the Excess Emissions 
Proposal in this final rulemaking.
    As EPA explained in the Emission Standards Proposal, EPA proposed 
to remove subparagraph (1)(c)3 from the SIP because, as FDEP notes in 
its April 1, 2022, SIP revision, the monitoring of stack emissions is 
regulated by SIP-approved Chapter 62-297, F.A.C., Stationary Sources--
Emissions Monitoring, and subparagraph (1)(c)3 is a discretionary 
ambient SO2 monitoring provision that is no longer needed in 
the SIP. Id. FDEP explains that the State has the authority and 
capability of setting up ambient air quality monitoring stations as 
needed. In addition, Rule 62-212.400(7) requires that the owner or 
operator of a major stationary source or major modification under the 
PSD program provide any required monitoring and analysis as required in 
40 CFR 52.21(m). Florida operates an approved plan for monitoring 
compliance with the SO2 NAAQS and may require owners of 
fossil fuel steam generators to conduct ambient monitoring as needed 
when constructing or modifying emissions units.
    Comment 5: Commenters speculate that specific plants are being 
removed from Rule 62-296.405, ``Fossil Fuel Steam Generators with More 
than 250 Million Btu Per Hour Heat Input,'' because they no longer 
exist or are no longer permitted to operate. Commenters ask EPA to 
clarify why the plants are being removed.
    Response 5: Similar to the response to Comment 4, EPA's May 8, 
2023, Excess Emissions Proposal did not discuss the removal of 
SO2 and NOX standards for certain units from Rule 
62-296.405 because the Excess Emissions Proposal did not propose to 
remove them from the SIP. Instead, EPA proposed to remove the standards 
for certain units from Rule 62-296.405 in the Emissions Standards 
Proposal and explained the rationale for such removal in that notice. 
EPA did not receive any comments on the Emission Standards Proposal and 
is finalizing action on both the Emission Standards Proposal and the 
Excess Emissions Proposal in this final rulemaking.
    As EPA explained in the Emission Standards Proposal, EPA proposed 
to remove certain units from Rule 62-296.405 because Florida requested 
the

[[Page 51708]]

removal of SO2 and NOX standards from Rule 62-
296.405 for units that have permanently shut down \14\ or have more 
stringent federally enforceable limits in the SIP. See 88 FR 29591, 
29593-94.
---------------------------------------------------------------------------

    \14\ As explained in the Emission Standards Proposal, on March 
30, 2023, Florida withdrew its request to remove 62-296.405(1)(c)1.g 
and (1)(d)2., which include SO2 and NOX 
limits, respectively, for Florida Power and Light's Manatee plant, 
which has not shut down. EPA accordingly did not propose to approve 
the removal of these subparagraphs.
---------------------------------------------------------------------------

    Comment 6: A separate commenter expresses support for EPA's Excess 
Emissions Proposal and urges EPA to approve Florida's SIP revisions 
``and reinstate or issue new SIP calls for other states or local 
jurisdictions that have not yet revised their SSM provisions . . . .'' 
The commenter mentions that ``this will ensure a level playing field 
for all regulated facilities and promote environmental justice for all 
communities.''
    Response 6: EPA acknowledges the commenter's support for finalizing 
the Excess Emissions Proposal. To the extent that the comment refers to 
SIP calls for other states or local jurisdictions, the comment is 
outside the scope of this rulemaking, which addresses the 2015 SSM SIP 
Action with respect to Florida only.

III. Final Actions

    EPA is approving Florida's November 22, 2016, SIP revision (Excess 
Emissions Rule SIP Revision) consisting of revisions to Rule Section 
62-210.700, ``Excess Emissions.'' The revisions include the deletion of 
Rule 62-210.700(4), with the addition of equivalent language to Rules 
62-210.700(1) and (2); amendment of Rule 62-210.700(3), to clarify and 
restate the visible emissions and PM limits applicable during boiler 
cleaning (soot blowing) and load changes; addition of Rule 62-
210.700(6), which states that Rules 62-210.700(1) and (2) shall not 
apply after May 22, 2018, to either emission limits or unit-specific 
emission limits that have been incorporated into Florida's SIP; and 
addition of Rule 62-210.700(7), which states that after October 23, 
2016, Rules 62-210.700(1) and (2), shall not apply to new permit-
specific emission limits established pursuant to Florida's PSD and NNSR 
regulations (Rules 62-212.400 and 62-210.500). EPA has determined that 
Florida's Excess Emissions Rule SIP Revision is consistent with CAA 
requirements and adequately addresses the specific deficiencies that 
EPA identified in the 2015 SSM SIP Action with respect to the Florida 
SIP.
    Additionally, EPA is approving Florida's SIP revisions consisting 
of SSM-related and other changes to Rule 62-296.405, ``Existing Fossil 
Fuel Steam Generators with Greater than or Equal to 250 Million Btu Per 
Hour Heat Input,'' \15\ and Rule 62-296.570, ``Reasonably Available 
Control Technology (RACT)--Requirements for Major VOC- and 
NOX-Emitting Facilities''; removal of the sulfur dioxide 
emission limit in Rule 62-296.402, ``Sulfuric Acid Plants''; and 
removal of the nitrogen oxides emission limit in Rule 62-296.408, 
``Nitric Acid Plants.'' Further, EPA is approving into Florida's SIP 
source-specific SO2 and NOX emission limits and 
construction permit conditions for five SO2 emissions units 
and two NOX emissions units. EPA finds that Florida's April 
1, 2022, SIP revision and the September 30, 2022, Supplemental SSM SIP 
Revision are consistent with CAA requirements and adequately address 
the additional regulations identified by the State as problematic.
---------------------------------------------------------------------------

    \15\ The September 30, 2022, SIP revision includes the following 
typographical errors: (1) In paragraph 62-296.405(6)(b) as shown on 
page 33 of 126 in the submittal, one sentence (``In lieu of EPA 
Method 17, 5, 5B, or 5F . . . .'') appears in two places. The 
amendments to the State effective version of Rule 62-296.405, which 
start at page 73 of 126, show the revised text correctly at page 75 
of 126 in the SIP submittal. (2) In paragraph 62-296.405(7)(a)4. as 
shown on page 35 of 126, two rule cross-references are not shown as 
revised. The amendments to the State effective version of Rule 62-
296.405 show the revised cross-references correctly at page 77 of 
126. (3) In paragraph 62-296.405(7)(b) as shown on page 35 of 126, a 
rule cross-reference is not shown as revised. The amendments to the 
State effective version of the rule show the revised cross-reference 
correctly at page 77 of 126.
---------------------------------------------------------------------------

IV. Incorporation by Reference

    In this document, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with the requirements of 1 
CFR 51.5, and as discussed in Sections I through III of this preamble, 
EPA is finalizing the incorporation by reference of Florida Rule 62-
210.700, ``Excess Emissions,'' state effective October 23, 2016, which 
set a schedule by which the exemptions from applicable emission limits 
for startups, shutdowns, and malfunctions will be removed. EPA is also 
finalizing the incorporation by reference of the following Florida 
Rules: 62-296.402, ``Sulfuric Acid Plants,'' removing specific emission 
limits from the Florida SIP, state effective June 23, 2022, except for 
62-296.402(1), 62-296.402(2)(a)2., 62-296.402(2)(b)2., and 62-
296.402(3)(b); 62-296.405, ``Existing Fossil Fuel Steam Generators with 
Greater than or Equal to 250 Million Btu Per Hour Heat Input,'' 
revising monitoring requirements and clarifying applicability, state 
effective June 23, 2022, except for 62-296.405(4)(a)2. through 5., 62-
296.405(4)(a)8. and 9., 62-296.405(4)(b)1. and 2., 62-296.405(4)(b)4., 
and 62-296.405(5)(c).; 62-296.408, ``Nitric Acid Plants,'' removing 
specific emission limits, state effective November 23, 1994, except for 
62-296.408(2); and 62-296.570, ``Reasonably Available Control 
Technology (RACT)--Requirements for Major VOC- and NOX-
Emitting Facilities,'' removing an exemption from RACT requirements 
during startups, shutdowns, and malfunctions, state effective June 23, 
2022. Additionally, EPA is finalizing the incorporation by reference of 
the specified new operating parameters, SO2 emission caps, 
and compliance monitoring, recordkeeping, and reporting requirements 
for emission units EU 066 (SAP E) and EU 067 (SAP F) at Nutrien White 
Springs (Permit No. 0470002-132-AC),\16\ state effective January 1, 
2023; EU 004 (SAP 10) and EU 005 (SAP 11) at Mosaic South Pierce 
(Permit No. 1050055-037-AC),\17\ state effective April 1, 2023; and EU 
004 at TECO-Polk (Permit No. 1050233-050-AC),\18\ state effective 
January 1, 2023. The SO2 emission standards specified in 
each permit are the basis for the removal of other SO2 
emission limits from the SIP. Finally, EPA is finalizing the 
incorporation by reference of the specified new operating parameters, 
NOX emission caps, and compliance monitoring, recordkeeping,

January 1, 2023. The NOX emission standards specified in 
each permit are the basis for the removal of other NOX 
emission limits from the SIP. EPA has made, and will continue to make, 
these materials generally available through www.regulations.gov and at 
the EPA Region 4 office (please contact the person identified in the 
For Further Information Contact section of this preamble for more 
information). Therefore, these materials have been approved by EPA for 
inclusion in the SIP, have been incorporated by reference by EPA into 
that plan, are fully federally enforceable under sections 110 and 113 
of the CAA as of the effective date of the final rulemaking of EPA's 
approval, and will be incorporated by reference in the next update to 
the SIP compilation.\21\

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. See 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. These actions merely 
approve state law as meeting Federal requirements and does not impose 
additional requirements beyond those imposed by state law. For that 
reason, these actions:
     Are not significant regulatory actions subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 14094 (88 FR 21879, April 11, 2023);
     Do not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     Are 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.);
     Do 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);
     Do not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Are not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a state program;
     Are not significant regulatory actions subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
     Are 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.
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where EPA or an Indian tribe has 
demonstrated that a tribe has jurisdiction. In those areas of Indian 
country, these actions do not have tribal implications as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000), nor will they 
impose substantial direct costs on tribal governments or preempt tribal 
law.
    Executive Order 12898 (Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations, 59 FR 7629, 
Feb. 16, 1994) directs Federal agencies to identify and address 
``disproportionately high and adverse human health or environmental 
effects'' of their actions on minority populations and low-income 
populations to the greatest extent practicable and permitted by law. 
EPA defines environmental justice (EJ) as ``the fair treatment and 
meaningful involvement of all people regardless of race, color, 
national origin, or income with respect to the development, 
implementation, and enforcement of environmental laws, regulations, and 
policies.'' EPA further defines the term fair treatment to mean that 
``no group of people should bear a disproportionate burden of 
environmental harms and risks, including those resulting from the 
negative environmental consequences of industrial, governmental, and 
commercial operations or programs and policies.''
    The FDEP did not evaluate EJ considerations as part of its SIP 
submittal; the CAA and applicable implementing regulations neither 
prohibit nor require such an evaluation. EPA did not perform an EJ 
analysis and did not consider EJ in these actions. Due to the nature of 
the actions being taken here, these actions are expected to have a 
neutral to positive impact on the air quality of the affected area. 
Consideration of EJ is not required as part of these actions, and there 
is no information in the record inconsistent with the stated goal of 
E.O. 12898 of achieving EJ for people of color, low-income populations, 
and Indigenous peoples.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing these actions and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. These actions are not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of these actions must be filed in the United States Court of Appeals 
for the appropriate circuit by October 3, 2023. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of these actions 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. These actions may not be challenged later in proceedings to 
enforce its requirements. See section 307(b)(2).
