Designation of Areas for Air Quality Planning Purposes; Indiana; 
Redesignation of the Indianapolis Sulfur Dioxide Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: In accordance with the Clean Air Act (CAA), the Environmental 
Protection Agency (EPA) is redesignating the Indianapolis, Indiana area 
from nonattainment to attainment for the 2010 sulfur dioxide 
(SO2) National Ambient Air Quality Standard (NAAQS). The 
area is comprised of Perry, Wayne, and Center Townships in Marion 
County, Indiana. EPA is also approving, as a revision to the Indiana 
State Implementation Plan (SIP), Indiana's maintenance plan for this 
area. EPA proposed to approve Indiana's redesignation request and 
maintenance plan on April 30, 2019 and received two public comment 
submissions.

DATES: This final rule is effective on May 21, 2020.

I. What is being addressed by this document?

    On April 30, 2019 (84 FR 18195), EPA proposed to redesignate the 
Indianapolis SO2 nonattainment area to attainment of the 
2010 SO2 NAAQS. The Indianapolis SO2 
nonattainment area is comprised of Perry, Wayne, and Center Townships 
in Marion County, Indiana. An explanation of the CAA requirements for 
redesignation, a detailed analysis of Indiana's July 10, 2017 
redesignation request, and a discussion of EPA's reasons for proposing 
to redesignate were provided in the notice of proposed rulemaking 
(NPRM) and will not be restated here.

II. What comments did we receive on the proposed action and what are 
EPA's responses to those comments?

    The public comment period for EPA's proposed redesignation closed 
on May 30, 2019. EPA received two public comment submissions, which are 
addressed below.
    Comment: The Indiana Department of Environmental Management (IDEM) 
commented that it supported the proposed redesignation. IDEM also 
commented that EPA's proposed redesignation omitted Center Township 
from its description of the Indianapolis SO2 nonattainment 
area and requested that this error be corrected.
    EPA Response: EPA affirms its intent to approve the redesignation 
of the entire Indianapolis SO2 nonattainment area, which 
includes Center Township, Perry Township, and Wayne Township in Marion 
County. Two facilities addressed in EPA's April 30, 2019 proposal are 
located in Center Township: Belmont Advanced Wastewater Treatment Plant 
(formerly Indianapolis Sludge Incinerator), and the Citizen's Thermal-
Perry K steam generation plant. The April 30, 2019 proposal discussed 
the permanent and enforceable SO2 emission reductions which 
have occurred at these two facilities. The enforceable requirements for 
these facilities, adopted into the SIP at 326 IAC 7-4-2.1, include new 
controls at the Belmont Advanced Wastewater Treatment Plant and an 
enforceable change from coal to natural gas as fuel for Citizen's 
Thermal-Perry K. EPA finds that the redesignation requirements for 
Center Township have been met, and therefore, EPA intends to include 
Center Township in the final redesignation action for the Indianapolis 
SO2 nonattainment area.
    Comment: A second commenter stated that Indiana is subject to a SIP 
call issued under CAA section 110(k)(5), and that EPA may not 
redesignate the Indianapolis area because ``the state must have an 
approved SIP under section 110(k).'' The commenter contends that the 
Indiana SIP provision covered by the SIP call is generally

[[Page 30845]]

applicable throughout the State, and unlawfully allows exemptions from 
emission limits during periods of malfunction. The commenter states 
that this provision creates a risk that Indiana sources could cause 
violations of the NAAQS. Accordingly, the commenter contends that EPA 
``cannot'' approve any redesignation requests for Indiana ``until the 
state addresses the substantial inadequacy identified by EPA in the SIP 
call.''
    EPA Response: As an initial matter, although the commenter does not 
specifically identify which statutory provision pertaining to 
redesignation is at issue, we assume for purposes of our response that 
the commenter was referring to CAA section 107(d)(3)(E)(ii), which 
requires that ``the Administrator has fully approved the applicable 
implementation plan for the area under section [110(k) of the CAA].'' 
We disagree that a state being subject to an outstanding SIP call under 
section 110(k)(5) automatically means that CAA section 107(d)(3)(E)(ii) 
cannot be met, and that, as commenter avers, any nonattainment area in 
the state is subsequently barred from being redesignated to attainment.
    As background, we believe the commenter is referring to the 
startup, shutdown, and malfunction (SSM) SIP Call, an action EPA took 
on June 12, 2015 regarding how various SIP provisions treat excess 
emissions during periods of SSM. See 80 FR 33840. With respect to 
Indiana, EPA determined in the SSM SIP call that 326 IAC 1-6-4(a)--a 
provision EPA first approved into the SIP in 1984--was ``substantially 
inadequate to meet CAA requirements.'' Id. at 33966. IDEM has submitted 
a SIP amendment to revise 326 IAC 1-6-4(a) and EPA is still evaluating 
that submittal. See Letter from Keith Baugues, Assistant Commissioner, 
IDEM Office of Air Quality, to Robert A. Kaplan, Acting Regional 
Administrator, EPA Region 5 (January 31, 2017) (EPA-R05-OAR-2017-0462).
    For the reasons given below, we do not believe the SIP call for SIP 
rule 326 IAC 1-6-4(a) precludes the Indianapolis nonattainment area's 
redesignation to attainment for the 2010 SO2 NAAQS. First, a 
SIP call under section 110(k)(5) initiates a schedule for revising the 
presently approved SIP; it does not undo the SIP's status as ``fully 
approved.'' Rather, it conveys the Administrator's finding that the 
approved SIP has substantial inadequacies that must be revised and 
establishes a separate pathway for those revisions to occur. Until EPA 
approves a SIP revision, the presently approved SIP continues to apply 
and continues to be ``fully approved.'' As stated in EPA's longstanding 
interpretation of the redesignation provision, ``An area cannot be 
redesignated if a required element of its plan is the subject of a 
disapproval; a finding of failure to submit or to implement the SIP; or 
partial, conditional, or limited approval. However, this does not mean 
that earlier issues with regard to the SIP will be reopened. Regions 
should not reconsider those things that have already been approved. . . 
.'' Memorandum from John Calcagni, ``Procedures for Processing Requests 
to Redesignate Areas to Attainment,'' (September 4, 1992) (``Calcagni 
Memo'') at 3. See also Gen. Motors Corp. v. United States, 496 U.S. 
530, 540 (1990) (``the approved SIP is the applicable implementation 
plan during the time a SIP revision proposal is pending'') (citing 
numerous cases); Southwestern Pa. Growth Alliance v. Browner, 144 F.3d 
984, 989-990 (6th Cir. 1998) (affirming EPA's interpretation in the 
Calcagni Memo). Notably absent from the list of CAA section 110 
provisions in the Calcagni Memo that would bar EPA from finding that a 
SIP was fully approved--including disapproval or partial approval under 
section 110(k)(3), a finding of failure to submit under section 
110(c)(1)(A), and conditional approval under section 110(k)(4)--is an 
action under the SIP call provision in section 110(k)(5). We therefore 
do not agree with the commenter that being subject to a SIP call bars 
Indiana from seeking redesignation for every nonattainment area in its 
state.
    Moreover, to the extent that the commenter is asserting that the 
existence of an SSM provision in Indiana's SIP could lead to 
violations, and thereby preclude redesignation, we disagree. The 
specific SSM provision implicated in the SIP call in 326 IAC 1-6-4(a) 
addresses malfunctions that result in excess emissions. Under the 
State's maintenance plan, the State commits to enforce all measures 
necessary to maintain the 2010 SO2 NAAQS, which would 
include ensuring that malfunctions affecting those measures are 
remedied. The State also commits to investigate and take action if 
significant increases in ambient SO2 levels in a 
redesignated area occur, so as to ensure continuing maintenance of the 
NAAQS. Therefore, EPA finds that Indiana's maintenance plan can address 
malfunctions which may affect a redesignated area.
    The SIP provision at 326 IAC 1-6-4(a) has no bearing on 
Indianapolis's ability to attain and maintain the 2010 SO2 
NAAQS. In its air quality modeling showing attainment in Indianapolis, 
as cited in the April 30, 2019 proposed redesignation, IDEM identified 
six major sources of SO2 as the main contributors to ambient 
SO2 concentrations in Indianapolis, and applied emission 
reductions to them to provide for attainment of the 2010 SO2 
NAAQS. SIP rule 326 IAC 1-6-4(a) does not apply to those major sources; 
it applies only to non-major sources whose potential emissions are so 
small that their sole permitting requirement is either a registration 
permit or minor source permit under either 326 IAC 2-5.1 or 326 IAC 2-
6.1, respectively. By contrast, the six major sources of SO2 
are subject to the permanent, enforceable SO2 emission 
limitations codified at 326 IAC 7-4-2.1, a rule that has been fully 
approved into the Indiana SIP.\1\ They also have major source operating 
permits issued by IDEM pursuant to rules approved by EPA under title V 
of the CAA and 40 CFR part 70, and those permits incorporate the SIP 
limits. The permanent and enforceable SO2 emission 
reductions at those six sources--which Indiana demonstrated will 
provide for attainment in Indianapolis--are not affected in any way by 
326 IAC 1-6-4(a). EPA's finding here is consistent with prior 
redesignation actions. See, e.g., 79 FR at 55649, the September 17, 
2014 final redesignation of the Phoenix-Mesa area (redesignating an 
area, notwithstanding the existence of SSM provisions, where ``all of 
the specific control measures relied upon by the state for numeric 
credit for attainment and maintenance planning purposes, with very 
minor exceptions, apply to'' sources not impacted by those SSM 
provisions).
---------------------------------------------------------------------------

    \1\ As discussed below, the commenter appears to have been 
mistaken about the status of 326 IAC 7-4-2.1. That provision was 
approved into Indiana's SIP on March 22, 2019 (84 FR 10692), prior 
to EPA's April 30, 2019 proposal to redesignate the Indianapolis 
nonattainment area.
---------------------------------------------------------------------------

    EPA's finding is also consistent with another finding in the 
September 17, 2014 final redesignation of the Phoenix-Mesa area, which 
concludes that the emissions of the sources in that action which were 
impacted by SSM provisions constituted such a small percentage of the 
inventory that they were unlikely to lead to violations. For the 
Indianapolis area, the total 2015 attainment year SO2 
inventory is 15,312 tons per year (tpy). The six major sources 
contributed a total of 14,967 tpy. The emission inventory included an 
additional 176 tpy in point source emissions that was not attributed to 
the six major sources. That 176 tpy of emissions represents only 1.1 
percent of the total attainment inventory. Indiana's attainment year 
inventory did not

[[Page 30846]]

specify the individual sources whose emissions made up the 176 tpy, but 
if that entire total was assumed to be emitted by a set of small 
SO2 sources subject to 326 IAC 1-6-4(a), then this is the 
maximum portion of the attainment emission inventory which could 
potentially be put at risk by the SIP call provision. As noted in the 
April 30, 2019 proposed redesignation, Indiana's modeled attainment 
demonstration gave a final ambient air quality result, including 
background, of 191.1 micrograms per cubic meter, which is equivalent to 
73 parts per billion (ppb), or 97 percent of the standard. Even if all 
the sources subject to 326 IAC 1-6-4(a) released excess SO2 
emissions during malfunctions, we expect that the Indianapolis area 
would still meet the 2010 SO2 NAAQS. The current monitored 
design value for the Indianapolis area (covering the three-year period 
2016-2018) is 8 ppb, which is 11 percent of the 2010 SO2 
NAAQS, so the risk of malfunctions related to the SSM SIP call rule 
causing a monitored violation is very low.
    EPA concludes that because the SIP call rule only applies to 
sources emitting a very small percentage of the total SO2 
emissions in the Indianapolis area, the risk suggested by the commenter 
that the SIP call provision could lead to violations of the 2010 
SO2 NAAQS is very low, and therefore the existence of that 
SIP provision does not undermine or preclude the approval of Indiana's 
redesignation request for the Indianapolis area.
    Comment: EPA has not approved all aspects of Indiana's 
infrastructure SIP under section 110 of the CAA, even though an area 
must meet ``all applicable requirements for the area under section 110 
and Part D'' before being redesignated. EPA thus ``cannot'' approve any 
redesignation request for Indiana until the state fully addresses all 
infrastructure requirements under CAA section 110, including interstate 
transport and visibility. The commenter specifically cited ``the 
interstate transport prongs 1 and 2 of 110(a)(2)(D)(i)(I), prong 3 for 
visibility, and 110(a)(2)(J) for visibility.''
    EPA Response: EPA does not agree that we are precluded from 
approving any redesignation for any nonattainment area in the state of 
Indiana until the state has met all CAA section 110 infrastructure 
requirements. CAA section 107(d)(3)(E)(v) states that EPA may not 
redesignate a nonattainment area to attainment unless ``the State 
containing such area has met all requirements applicable to the area 
under section [110] of this title and part D of this subchapter.'' The 
statute does not specify how EPA is to determine which requirements in 
section 110 and Part D are ``applicable'' for purposes of evaluating a 
state's redesignation request, and courts have agreed that this 
provision is ambiguous. See Wall v. EPA, 265 F.3d 426, 439 (6th Cir. 
2001) (``Although ``applicable'' could be interpreted as limiting only 
the geographical area to which the statutory requirements must apply, 
it can also be interpreted as limiting the number of actual 
requirements within CAA section 110 and Part D that apply to a given 
area.''); see also Sierra Club v. EPA, 375 F.3d 537, 541 (7th Cir. 
2004) (finding the term ``applicable'' in CAA section 107(d)(3)(E)(ii) 
to be ``a protean word that takes color from context; it lacks a 
single, enduring meaning'').
    Commenter's interpretation of that provision would suggest that EPA 
is precluded from redesignating any area in the state, for any 
pollutant, until every section 110 infrastructure requirement has been 
met by the state and approved into the SIP by EPA. We think this 
interpretation of CAA section 107(d)(3)(E)(v) is unreasonable. States 
are required to submit section 110 infrastructure SIPs within 3 years 
of the promulgation of a new NAAQS (see CAA section 110(a)(1)), and 
taking commenter's interpretation at face value, states would be 
precluded from seeking redesignation of an area for one NAAQS if it had 
outstanding infrastructure obligations under an entirely different 
NAAQS. We think this reading of the CAA is patently unreasonable and 
not what Congress intended.
    EPA's longstanding interpretation of ``applicable'' in CAA section 
107(d)(3)(E)(v) focuses the Agency's review for purposes of 
redesignation to those requirements in section 110 and Part D that are 
linked to an area's nonattainment status for the specific NAAQS at 
issue and that will no longer need to be complied with upon 
redesignation. Requirements unlinked to an area's nonattainment status 
for a particular NAAQS will continue to apply after the area is 
redesignated to attainment, and an area failing to comply with those 
obligations would remain subject to all related CAA consequences, 
including the possibility of sanctions. EPA has applied this 
interpretation to conformity and oxygenated fuels requirements and 
section 184 ozone transport requirements. In Wall v. EPA, the 6th 
Circuit upheld this interpretation, affirming EPA's determination that 
a state's failure to submit a SIP addressing transportation conformity 
requirements was not a basis upon which to deny the state's request for 
redesignation for a particular area in the state, because that 
requirement was not ``applicable'' under CAA section 107(d)(3)(E)(v). 
265 F.3d at 440.
    With respect to the specific infrastructure elements cited by the 
commenter--the interstate transport requirements in CAA sections 
110(a)(2)(D)(i)(I) and the requirements in CAA sections 
110(a)(2)(D)(i)(II) and 110(a)(2)(J) to address visibility--these 
elements are not ``applicable'' requirements for purposes of CAA 
section 107(d)(3)(E)(v). As noted above, these requirements are not 
linked to the area's designation as nonattainment for SO2 
and apply regardless of whether EPA redesignates the Indianapolis area. 
In any case, EPA approved the visibility element of CAA section 
110(a)(2)(D)(i)(II), known as ``Prong 4,'' \2\ for Indiana's 
SO2 infrastructure SIP on September 6, 2019 (84 FR 46889), 
so the comment that this requirement is missing from the infrastructure 
SIP is no longer accurate. In addition, on February 27, 2015 (80 FR 
10644), EPA proposed to find that the requirements in CAA section 
110(a)(2)(J) to address visibility were not germane to the State's 
infrastructure SIP for the 2010 SO2 NAAQS, and thus EPA took 
no action on that element in its final action on August 14, 2015 (80 FR 
48733). To the extent that commenter is alleging that there are 
additional unapproved infrastructure SIP requirements under CAA section 
110 besides the CAA section 110(a)(2)(D)(i)(I) transport prongs which 
EPA has not taken action upon, that Indiana would need to comply with 
before it may be redesignated, Indiana has met all of its other 
infrastructure requirements under CAA section 110. See 80 FR 48733 
(August 14, 2015) (approving all other infrastructure SIP elements).
---------------------------------------------------------------------------

    \2\ Commenter cited ``prong 3 for visibility.'' In CAA section 
110(a)(2)(D)(i)(II), Prong 3 is ``interstate transport-prevention of 
significant deterioration,'' and Prong 4 is ``interstate transport-
protect visibility.''
---------------------------------------------------------------------------

    For all these reasons, EPA concludes that Indiana has met all CAA 
section 110 SIP elements applicable for purposes of redesignation.
    Comment: EPA lists several Federal rulemakings as establishing 
allowable limits for six modeled sources. These include the Cross-State 
Air Pollution Rule (CSAPR), Mercury and Air Toxics Standards (MATS), 
and the National Emission Standards for Hazardous Air Pollutants 
(NESHAP) for Industrial Commercial and Institutional Boilers and 
Process Heaters. The commenter states that while EPA's proposal 
explained that these limits have been

[[Page 30847]]

adopted at 326 IAC 7-4-2.1, the commenter believes that the Federal 
rulemakings cannot have themselves established appropriate enforceable 
limits for addressing hourly SO2, because they were not 
written to do so. The commenter states that if EPA expects any co-
benefits from these Federal programs, then it must first quantify those 
reductions, and then require Indiana to include these measures in an 
approved SIP revision.
    EPA Response: The April 30, 2019 proposed redesignation included a 
statement which inadvertently oversimplified the role of CSAPR, MATS, 
and the NESHAP in Indiana's achieving SO2 reductions in 
Indianapolis. In its July 17, 2017 submittal, Indiana stated that some 
emission limits for the Indianapolis facilities were established in 
response to those Federal rulemakings, which several facilities had 
already worked to comply with. However, Indiana did not rely on the 
existence of Federal rulemakings alone, but rather codified the 
facilities' SO2 emission limits in 326 IAC 7-4-2.1. The 
limits in 326 IAC 7-4-2.1 were fully approved into Indiana's SIP on 
March 22, 2019 (84 FR 10692) and are permanent, enforceable, hourly 
emission limits. Indiana's modeled demonstration of attainment, 
detailed in EPA's NPRM on Indiana's nonattainment SO2 SIP 
for Indianapolis, August 15, 2018 (83 FR 40487), showed that the 
emission limits in 326 IAC 7-4-2.1 are adequate to attain and maintain 
the 2010 SO2 NAAQS in the Indianapolis nonattainment area.
    Comment: The commenter stated that, based on information in an EPA 
website, 326 IAC 7-4-2.1 was not SIP-approved at the time of EPA's 
proposed redesignation. The commenter asserted that EPA could not rely 
on emission reductions from the rule to determine attainment of the 
SO2 NAAQS.
    EPA Response: Indiana revised its SO2 rule for Marion 
County, codified at 326 IAC 7-4-2.1, and submitted it as a SIP revision 
on October 2, 2015. EPA approved these rules on March 22, 2019 (84 FR 
10692). The rule was fully approved into the SIP at the time of EPA's 
April 30, 2019 proposed redesignation of the Indianapolis 
SO2 nonattainment area. EPA's website has been updated 
accordingly.
    Comment: EPA must clarify that Indiana is required to submit a 
second ten-year maintenance plan by the eighth year of the first ten-
year maintenance period. Since Indiana's maintenance plan is effective 
to December 31, 2030, Indiana should be required to submit a second 
ten-year maintenance plan by December 31, 2028, and not eight years 
after EPA's approval of this maintenance plan (which, if EPA publishes 
the final rule in 2019 would be 2027).
    EPA Response: CAA section 175A(b) requires the State to submit an 
additional revision of the maintenance plan eight years after 
redesignation of the area. Indiana has committed in its July 10, 2017 
submittal to fulfill this CAA requirement.

III. What action is EPA taking?

    EPA is redesignating the Indianapolis SO2 nonattainment 
area to attainment of the 2010 SO2 NAAQS. This area consists 
of Center, Perry, and Wayne Townships in Marion County, Indiana. EPA is 
also approving Indiana's SO2 maintenance plan for the 
Indianapolis area.
    In accordance with 5 U.S.C. 553(d), EPA finds there is good cause 
for these actions to become effective immediately upon publication. 
This is because a delayed effective date is unnecessary due to the 
nature of a redesignation to attainment, which relieves the area from 
certain CAA requirements that would otherwise apply to it. The 
immediate effective date for this action is authorized under both 5 
U.S.C. 553(d)(1), which provides that rulemaking actions may become 
effective less than 30 days after publication if the rule ``grants or 
recognizes an exemption or relieves a restriction,'' and section 
553(d)(3), which allows an effective date less than 30 days after 
publication ``as otherwise provided by the agency for good cause found 
and published with the rule.'' The purpose of the 30-day waiting period 
prescribed in section 553(d) is to give affected parties a reasonable 
time to adjust their behavior and prepare before the final rule takes 
effect. This rule, however, does not create any new regulatory 
requirements such that affected parties would need time to prepare 
before the rule takes effect. Rather, this rule relieves the State of 
planning requirements for this SO2 nonattainment area. For 
these reasons, EPA finds good cause under 5 U.S.C. 553(d)(3) for these 
actions to become effective on the date of publication of these 
actions.

IV. Statutory and Executive Order Reviews

    Under the CAA, redesignation of an area to attainment and the 
accompanying approval of the maintenance plan under CAA section 
107(d)(3)(E) are actions that affect the status of the geographical 
area and do not impose any additional regulatory requirements on 
sources beyond those required by state law. A redesignation to 
attainment does not in and of itself impose any new requirements, but 
rather results in the application of requirements contained in the CAA 
for areas that have been redesignated to attainment. Moreover, 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 these reasons, 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 it is not a significant regulatory 
action 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, 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, the rule does not have tribal implications as specified by 
Executive Order 13175 (65 FR 67249, November 9, 2000), because 
redesignation is an action that affects the status of a geographical 
area and does not impose any new regulatory requirements on tribes, 
impact any existing sources of air pollution on tribal lands, nor 
impair the maintenance of the NAAQS in tribal lands.
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    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 July 20, 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 may not be challenged later in proceedings to 
enforce its requirements. (See section 307(b)(2).)
