Entities potentially affected directly by this proposed rule
include State, local and Tribal governments, as well as Federal Land
Managers (FLMs) responsible for protection of visibility in mandatory
Class I areas. Entities potentially affected indirectly by this
proposed rule include owners and operators of sources that emit
particulate matter equal to or less than 10 microns in diameter
(PM<INF>10</INF>), particulate matter equal to or less than 2.5 microns
in diameter (PM<INF>2.5</INF> or fine PM), sulfur dioxide
(SO<INF>2</INF>), oxides of nitrogen (NO<INF>X</INF>), volatile organic
compounds and other pollutants that may cause or contribute to
visibility impairment. Others potentially affected indirectly by this
proposed rule include members of the general public who live, work or
recreate nearby or in mandatory Class I areas affected by visibility
impairment. Because emissions sources that contribute to visibility
impairment in Class I areas also may contribute to air pollution in
other areas, members of the general public may also be affected by this
proposed rulemaking.

III. What action is the EPA proposing to take?
The EPA is proposing to revise the due date for the next required
regional haze SIP revision from the current due date of July 31, 2028,
to a revised due date of July 31, 2031. The revised SIP due date would
apply to periodic comprehensive State implementation plans developed
for the third regional haze implementation period.\1\ The proposed
change to the third regional haze SIP due date has no effect on prior
due dates for the second \2\ or prior \3\ implementation periods under
the existing Regional Haze Rule. The EPA is also proposing to revise 40
CFR 51.308(f) to clarify that the due date for the fourth
implementation period SIPs will still be due on July 31, 2038. The end
date for the third implementation period is not being revised and will
remain in 2038. Therefore, State plans will remain focused on emissions
reduction measures designed to achieve reasonable progress by 2038, as
required by the current rule. Other than the proposed change to the
next due date for periodic comprehensive SIP revisions (i.e., for those
currently due in 2028) and clarifying the due date for future periodic
comprehensive SIP revisions (i.e., for those that will still be due in
2038), the EPA is proposing no other changes for due dates for future
periodic comprehensive SIP revisions or future progress reports.
---------------------------------------------------------------------------
\1\ While the EPA uses ``implementation period'' in this notice
of proposed rulemaking, we note that ``planning period'' may be used
in other Regional Haze guidance, policy, and rules. The terms may be
used interchangeably and convey the same meaning.
\2\ SIP revisions for the second implementation period were due
July 31, 2021.
\3\ SIPs for the first implementation period were due December
17, 2007.
---------------------------------------------------------------------------
The EPA is proposing a third implementation period deadline change
from July 31, 2028, to July 31, 2031, for several reasons, as described
more fully later in this proposed action. The EPA intends to propose
revisions to the Regional Haze Rule through a notice-and-comment
rulemaking. Once finalized, these revisions would impact the third
implementation period SIPs. The proposed extension rule revisions also
clarify that the due date for the fourth implementation period SIPs
remains 2038 and does not alter the previously established SIP
schedule. The current SIP revision deadline of July 31, 2028, is not
expected to provide States with enough time to develop their
[[Page 104473]]
regional haze SIP revisions to reflect any updated requirements based
on the anticipated forthcoming rule revisions. In addition, extending
the third implementation period SIP due date allows States to obtain
and consider the potential emissions reductions resulting from
implementing other near-term regulatory programs,\4\ including
implementation of measures adopted as part of the regional haze second
implementation period. The SIP due date extension would also allow
States to develop SIP revisions for the third implementation period
that are more integrated with State planning for these other programs.
This was an advantage that was identified in feedback from States over
prior implementation periods and that is anticipated to result in
greater environmental progress than if planning for these multiple
programs were not as well integrated.\5\
---------------------------------------------------------------------------
\4\ This includes programs such as such as the 2015 8-hour Ozone
NAAQS Serious and Severe Area SIPs, implementation of the 2024
annual PM<INF>2.5</INF> NAAQS revised standard, CAA section 111(d)
EGU State plans, and CAA section 111(d)--OOOO(c) Oil and Gas State
plans.
\5\ In early 2024, the EPA conducted a series of outreach
webinars to inform stakeholders of EPA's intent to revise the
Regional Haze Rule for the third implementation period. Comments on
potential rule revisions were submitted to a non-regulatory docket
(EPA-HQ-OAR-2023-0262). Many commenters requested that the EPA
extend the third implementation period SIP deadline by 3-5 years
following any major revision of the Regional Haze Rule given that
regional haze SIP development requires many years and States do not
yet know how any major regulatory revisions will impact the SIP
development process. See FN 21 for more information.
---------------------------------------------------------------------------
While the EPA is proposing the specific extended third
implementation period SIP deadline of July 31, 2031, and clarifying the
deadline remains July 31, 2038 for the fourth implementation period
SIPs, the EPA is also soliciting comment on alternative deadline
options for the third implementation period Haze SIPs. Commenters may
suggest alternate deadline options for the third implementation period
regional haze SIP revisions by submitting alternatives to Docket ID No.
EPA-HQ-OAR-2023-0262 at <a href="http://www.regulations.gov">http://www.regulations.gov</a>. If commenters
provide feedback identifying a date other than July 31, 2031, the EPA
asks that comments also include the specific basis and/or rationale for
the identified date.
IV. What is the background for the EPA's proposed action?
A. Regional Haze
Regional haze is visibility impairment that is produced by a
multitude of sources and activities that are located across a broad
geographic area and emit PM<INF>10</INF>, PM<INF>2.5</INF> (e.g.,
sulfates, nitrates, organic carbon, elemental carbon and soil dust) and
their precursors (e.g., SO<INF>2,</INF> NO<INF>X</INF> and, in some
cases, ammonia and volatile organic compounds). Fine particle
precursors react in the atmosphere to form PM<INF>2.5</INF>, which
impairs visibility by scattering and absorbing light. This light
scattering reduces the clarity, color and visible distance that one can
see. Particulate matter can also cause serious health effects in humans
(including premature death, heart attacks, irregular heartbeat,
aggravated asthma, decreased lung function and increased respiratory
symptoms) and contribute to environmental effects such as acid
deposition and eutrophication.
B. Requirements for Regional Haze SIPs for the Second Implementation
Period
In 2017, the EPA revised the Regional Haze Rule (2017 RHR) to
clarify States' obligations and streamline certain regional haze
requirements for the second implementation period.\6\ These revisions
to the regional haze program focused on the requirement that States'
SIPs contain long-term strategies for making reasonable progress
towards the national visibility goal. These reasonable progress
requirements as revised in the 2017 rulemaking are codified at 40 CFR
51.308(f). Among other changes, the 2017 RHR adjusted the deadline for
States to submit their second implementation period SIPs,\7\ clarified
the order of analysis and the relationship between the reasonable
progress goals and the long-term strategy and focused on making
visibility improvements on the days with the most anthropogenic
visibility impairment, as opposed to the days with the most visibility
impairment overall. The EPA also revised requirements of the visibility
protection program related to periodic progress reports and FLM
consultation.
---------------------------------------------------------------------------
\6\ 82 FR 3078 (January 10, 2017).
\7\ The 2017 RHR extended the deadline to submit second
implementation period SIPs from July 31, 2018, to July 31, 2021. Id.
at 3116-3118.
---------------------------------------------------------------------------
Currently, 40 CFR 51.308(f) requires States to submit periodic
comprehensive revisions of implementation plans (referred to in this
document as periodic comprehensive SIP revisions) addressing regional
haze visibility impairment by no later than July 31, 2021, July 31,
2028, and every 10 years thereafter. All 50 States, the District of
Columbia, and the U.S. Virgin Islands are required to submit regional
haze SIPs satisfying the applicable requirements for the second
implementation period of the regional haze program. Each SIP must
contain a long-term strategy for making reasonable progress toward
meeting the national goal of remedying any existing and preventing any
future anthropogenic visibility impairment in Class I areas.\8\ To this
end, 40 CFR 51.308(f) lays out the process by which States determine
what constitutes their long-term strategies, with the order of the
requirements in 40 CFR 51.308(f)(1) through (3) generally mirroring the
order of the steps in the reasonable progress analysis \9\ and 40 CFR
51.308(f)(4) through (6) containing additional, related requirements.
In addition to satisfying the requirements at 40 CFR 51.308(f) related
to reasonable progress, the regional haze SIP revisions for the second
implementation period must address the requirements in 40 CFR
51.308(g)(1) through (5) pertaining to periodic reports describing
progress towards the reasonable progress goals (RPGs), 40 CFR
51.308(f)(5), as well as requirements for FLM consultation that apply
to all visibility protection SIPs and SIP revisions.\10\
---------------------------------------------------------------------------
\8\ CAA 169A(b)(2)(B).
\9\ The EPA explained in the 2017 RHR Revisions that we were
adopting new regulatory language in 40 CFR 51.308(f) that, unlike
the structure in 51.308(d), ``tracked the actual planning
sequence.'' (82 FR 3091, January 10, 2017).
\10\ 40 CFR 51.308(i).

the 2017 RHR revisions, please refer to Section III. Overview of
Visibility Protection Statutory Authority, Regulation, and
Implementation of ``Protection of Visibility: Amendments to
Requirements for State Plans'' of the 2017 RHR.\11\

---------------------------------------------------------------------------
V. Proposed Rule Changes
The EPA has announced its intention to revise the Regional Haze
Rule, in part to incorporate lessons learned from the implementation of
the rule in the second implementation period. Given that such revisions
have not yet been proposed, we are proposing to extend the SIP due date
timeline to avoid a situation where the rule revisions are finalized
too close in time to the existing timeline, resulting in State
inability to meet that timeline. Therefore, we are proposing to extend
the SIP deadline in anticipation that it will be necessary to provide
States with sufficient time to take potential revisions into account
when developing their SIPs. Indeed, we expect that extending the
deadline to align with the
[[Page 104474]]
forthcoming Regional Haze Rule revisions will result in a more
effective program in terms of achieving the goal of improved visibility
in Class I areas by aligning programmatic objectives with an
opportunity for holistic air quality planning approaches across
multiple criteria air pollutants. In addition, we are also proposing
revisions that would clarify that the fourth implementation plans are
still due on July 31, 2038, and do not significantly alter the
originally intended SIP revision schedule.
Extension of the Next Regional Haze SIP Deadline From 2028 to 2031
The EPA is proposing to amend 40 CFR 51.308(f) to extend the
compliance deadline for the third periodic comprehensive SIP revisions
from July 31, 2028, to July 31, 2031. We are also proposing revisions
to clarify that the compliance deadline for the fourth periodic
comprehensive SIP revisions is still July 31, 2038. Periodic
comprehensive SIP revisions for the third implementation period would
be due on July 31, 2031, SIP revisions for the fourth implementation
period would be due on July 31, 2038, and future periodic comprehensive
SIP revisions would be due every 10 years thereafter. The EPA is not
proposing to change the end date for the third implementation period,
which will remain 2038 regardless of when States submit their SIP
revisions. The EPA is also not proposing to amend the due date for
third implementation period progress reports, which remain due in 2033.
The EPA is within its statutory authority to propose this deadline
extension.\12\ First, the EPA's proposal to extend the third
implementation period's submission deadline by 3 years will not impact
the EPA's statutory duty to ensure that reasonable progress towards
natural visibility is being made at Class I areas. Section 169A(a)(4)
of the CAA requires the EPA to promulgate regulations to assure (1)
reasonable progress toward meeting the national goal of preventing any
future and remedying any existing visibility impairment; and (2)
compliance with other regional haze requirements. Then, CAA section
169A(b) generally outlines what EPA must cover in those regulations.
Under CAA section 169A(b)(2)(B), regional haze SIP submissions must
include, among other things, a long-term, 10-to-15-year, strategy for
making reasonable progress toward meeting the national goal. Although
second implementation period SIPs were initially due in 2018, when the
EPA extended that deadline to 2021,\13\ the second implementation
period still ended in 2028. Therefore, the third implementation
period's long-term strategy could end anywhere between 2038-2043.
However, as outlined in this proposal, the EPA is proposing for the SIP
submission deadline to be 2031, with the third implementation period
still ending in 2038. Therefore, the timing of third implementation
period SIPs will still allow for a long-term strategy that meets the
statutory requirements and will not elongate the third implementation
period. This is especially true given that the due date for the fourth
periodic comprehensive SIP revisions is still July 31, 2038.
---------------------------------------------------------------------------
\12\ The EPA is authorized to promulgate the Regional Haze Rule
under CAA sections 110, 114, 121, 160-169, and 169A.
\13\ 82 FR 3078 at 30116-3118 (January 10, 2017).
---------------------------------------------------------------------------
The EPA acknowledges that extending the deadline to submit third
implementation SIPs by three years will also extend the timeframe for
additional measures to be added to the State's long-term strategy by
three years. However, between 2028 and 2031, existing regional haze
implementation plans that include measures deemed necessary for
reasonable progress for the first two implementation periods will
continue to be in place. Additionally, if a State would ever wish to
revise those measures being implemented under its current SIP, the
State would have to submit a SIP revision for EPA review. In that
review, the EPA is obligated to ensure, inter alia, that such a
revision does not contribute to an increase in anthropogenic visibility
impairment in any Class I area. Therefore, despite EPA's proposed 3-
year extension, the measures deemed necessary for reasonable progress
during the first two implementation periods will continue to ensure
reasonable progress from 2028 to 2031 and beyond, unless the State
submits a SIP revision.
Under the current rule, when determining what is necessary for
reasonable progress within a given implementation period, States must
consider the four statutory factors under CAA section 169(A)(g)(1).\14\
However, before considering the four statutory factors, States must
conduct photochemical modeling and/or other technical analyses to
estimate their contributions of anthropogenic visibility impairment in
various Class I areas nationwide. States then select sources for
analysis under the four statutory factors to determine if new controls
are necessary or if existing controls suffice to make reasonable
progress and justify their decisions within their SIP. As discussed
later in this section, States have indicated that it may take 4 years
to complete this work. Providing States sufficient time to develop
meaningful and comprehensive SIPs that address visibility improvement
goals ultimately helps ensure that the SIPs contain measures that are
necessary for reasonable progress and will in fact make progress
towards the national goal of eliminating existing and preventing future
visibility impairment.
---------------------------------------------------------------------------
\14\ In determining what measures are necessary for reasonable
progress, States must consider the cost of compliance, the time
necessary for compliance, the energy and nonair quality
environmental impacts of compliance, and the remaining useful life
of any existing source subject to such requirements (CAA section
169A(g)(1)).
---------------------------------------------------------------------------
Furthermore, while SIP development schedules can vary State-to-
State, regional haze SIPs often take longer than 2 years to develop due
to modeling and technical analyses that are performed up front, prior
to SIP development. As an example, the most recent Regional Haze Rule
revisions were published in January 2017 and gave States approximately
4.5 years from the publication date to submit final SIP revisions.\15\
Even with the 4-year notice, only 8 (out of 52 required) States
submitted SIPs by the July 31, 2021, compliance deadline for the second
implementation period. Multiple States claimed that the 4-year window
was an insufficient period of time in which to develop legally
compliant SIPs.\16\ While the EPA believes that States were given a
reasonable amount of time to develop and submit their SIPs for the
second implementation period, it is clear that States need time beyond
the current 2028 deadline to complete the necessary technical work
(which often includes photochemical modeling, as discussed earlier in
this section), make appropriate and reasonable decisions on the content
of their long-term strategies, fully document the work in a SIP
submittal, satisfy the FLM consultation and public comment
requirements, and sometimes lengthy State legislative requirements.
Based on this past experience, we estimate that States will need
approximately 4 years to complete this work. Given the current rule
revisions schedule, that aligns with a 2031 third implementation period
SIP due date.
---------------------------------------------------------------------------
\15\ See 40 CFR 51.308(f): ``Each State identified in Sec.
51.300(b) must revise and submit its regional haze implementation
plan revision to EPA by July 31, 2021, July 31, 2028, and every 10
years thereafter . . .''
\16\ See comments submitted to our non-regulatory docket (EPA-
HQ-OAR-2023-0262), available at <a href="https://www.regulations.gov/">https://www.regulations.gov/</a>.
---------------------------------------------------------------------------
Finally, extending the regional haze SIP due date will also allow
States to coordinate regional haze planning with other CAA regulatory
program planning,
[[Page 104475]]
including but not limited to the 2015 8-hr Ozone NAAQS Serious Area and
Severe Area SIPs,\17\ implementation of the 2024 annual
PM<INF>2.5</INF> NAAQS revised standard,\18\ CAA section 111(d)
electric generating unit (EGU) State Plans,\19\ and CAA section
111(d)--OOOO(c) Oil and Gas State Plans.\20\ With this proposed
extension, States would be able to gather more information on the
effects of these programs and develop periodic comprehensive SIP
revisions that are more integrated with State planning for these other
programs, an advantage that has been identified by States in comments
submitted to the non-regulatory docket.<SUP>21 22</SUP> The Regional
Haze Rule requires States to address the impacts of other regulatory
programs when developing their regional haze SIPs and States have
stressed the importance of coordination between programs. A number of
other regulatory programs will be taking effect in the coming years,
which presents a strategic opportunity for States to coordinate their
strategies to address significant sources of emissions. The EPA expects
this cross-program coordination to lead to better overall policies and
enhanced environmental protection.

\20\ Id.
\21\ In early 2024, the EPA solicited feedback from interested
parties on revisions to the Regional Haze Rule to improve
implementation of the regional haze third, and possibly later,
implementation period SIPs in advance of proposing rule revisions.
To facilitate this effort, the EPA conducted a series of
informational public webinars intended to help the public consider
different aspects of the current Regional Haze Rule relating to how
key aspects of the program could be implemented in future
implementation periods. Following the public webinar series, we
invited interested parties to submit comments and feedback to a non-
regulatory docket (EPA-HQ-OAR-2023-0262).
\22\ See comments submitted to our non-regulatory docket (EPA-
HQ-OAR-2023-0262), available at <a href="https://www.regulations.gov/">https://www.regulations.gov/</a>.
---------------------------------------------------------------------------
With this in mind, we are proposing this SIP due date extension for
several reasons. First, the EPA has indicated its intent to develop a
rulemaking that may substantively revise aspects of the Regional Haze
Rule, which would impact the third implementation period SIPs, and
possibly into future implementation periods. The public can track the
EPA's progress on rulemakings through the EPA's Regulatory Agenda,
which generally includes regulatory timelines.\23\ Therefore, the
current SIP revision deadline of July 31, 2028, will likely not provide
States sufficient time to thoughtfully develop their regional haze SIP
revisions to reflect any updated requirements based on the anticipated
timing of the forthcoming rule revisions. At this time, it is premature
to explain how the current requirements in 40 CFR 51.308(f) will
change; however, the EPA acknowledges that it has announced an
intention to revise the Regional Haze Rule for purposes of the third
implementation period on a timeline that is likely not consistent with
the current third implementation period SIP due date, as previously
described.

---------------------------------------------------------------------------
VI. Environmental Justice Considerations
When finalized, the proposed regulation will revise procedural and
timing aspects of the SIP requirements for visibility protection but
will not change the requirement that SIPs provide for reasonable
progress towards the goal of natural visibility conditions consistent
with the CAA timeline. Additionally, when finalized, the proposed
revision will apply a new timeline for SIP submission that will affect
all States.
The EPA acknowledges that the proposed delay in submitting SIP
revisions from 2028 to 2031 might cause delays in when sources must
comply with any new requirements. However, because neither the CAA nor
the existing Regional Haze Rule set specific deadlines for when sources
must comply with any new requirements in a State's next periodic
comprehensive SIP revision, States have substantial discretion in
establishing reasonable compliance deadlines for measures in their
SIPs. Given this, we expect to see a range of compliance deadlines in
the next round of regional haze SIPs from early in the third
implementation period to 2038, depending on the types of measures
adopted, whether or not these proposed rule changes are finalized.
Thus, the EPA believes the delay in the periodic comprehensive SIP
revision submission deadline from 2028 to 2031 will not meaningfully
reduce the overall progress towards better visibility made by the end
of 2038 and will not meaningfully adversely affect environmental
protection for all general segments of the population.
Since the revision applies nationally, the EPA anticipates there
may be areas impacted where conditions exist that have the potential to
result in disproportionate and adverse effects on communities with
environmental justice concerns. However, it is not practicable to
provide any more detailed assessment. Nonetheless, the EPA offered
meaningful engagement related to today's proposal above and beyond
minimum notice and comment rulemaking obligations. For example, today's
proposal was preceded by seeking comment on a wide array of issues
related to the implementation of the Regional Haze Program. EPA did
this through the opening of a non-regulatory docket, which occurred on
March 28, 2024, and will close December 31, 2024.\24\ So far, the EPA
has received 32 comments from different perspectives. Many of the
comments requested and supported the action being proposed today.
Consistent with legal requirements, the EPA is now seeking comment on
this specific proposal as well.
---------------------------------------------------------------------------
\24\ This docket will be open for public comment from March 28,
2024, to December 31, 2024, however, comments received after June
28, 2024, will be considered late and EPA may be unable to consider
comments received after this date.

VII. Statutory and Executive Order Reviews
Additional information about these statutes and Executive Orders
can be found at <a href="https://www.epa.gov/laws-regulations/laws-and-executive-orders">https://www.epa.gov/laws-regulations/laws-and-executive-orders</a>.
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 14094: Modernizing Regulatory Review
This action is not a significant regulatory action as defined in
Executive Order 12866, as amended by Executive Order 14094, and was
therefore not subject to a requirement for Executive Order 12866
review.
B. Paperwork Reduction Act (PRA)
This action does not impose any new information collection burden
under the PRA. OMB has previously approved the information collection
activities contained in the existing regulations and has assigned OMB
control number 2060-0704. This action simply proposes to extend the SIP
due date. The burden associated with developing and submitting SIPs is
covered in the existing information collection request. This action
does not impose an information collection burden because it does not
create an obligation for Regional offices, States, or sources to submit
new information to the EPA.
C. Regulatory Flexibility Act
This action will not have a significant economic impact on a
substantial number of small entities under the RFA. This action will
not impose any requirements on small entities. Small entities are not
subject to the requirements of this rule.
[[Page 104476]]
D. Unfunded Mandates Reform Act
I certify that this action does not contain an unfunded mandate as
described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or
uniquely affect small governments. The action imposes no enforceable
duty on any State, local or Tribal governments or the private sector.
E. Executive Order 13132: Federalism
This action does not have federalism implications. It will not have
substantial direct effects on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have Tribal implications as specified in
Executive Order 13175. It would not have a substantial direct effect on
one or more Indian Tribes. Furthermore, these proposed regulation
revisions do not affect the relationship or distribution of power and
responsibilities between the Federal government and Indian Tribes. The
CAA and the TAR establish the relationship of the Federal government
and Tribes in characterizing air quality and developing plans to
protect visibility in Class I areas. Thus, Executive Order 13175 does
not apply to this action.
G. Executive Order 13045: Protection of Children From Environmental
Health & Safety Risks
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that concern environmental health or safety risks
that the EPA has reason to believe may disproportionately affect
children, per the definition of ``covered regulatory action'' in
section 2-202 of the Executive Order. Therefore, this action is not
subject to Executive Order 13045 because it does not concern an
environmental health risk or safety risk. Since this action does not
concern human health, the EPA's Policy on Children's Health also does
not apply.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
This action is not subject to Executive Order 13211, because it is
not a significant regulatory action under Executive Order 12866.
I. National Technology Transfer and Advancement Act
This rulemaking does not involve technical standards.
J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations and
Executive Order 14096: Revitalizing Our Nation's Commitment to
Environmental Justice for All
The EPA believes that it is not practicable to assess whether the
human health or environmental conditions that exist prior to this
action result in disproportionate and adverse effects on communities
with environmental justice concerns. This action revises a procedural
requirement--a deadline for submission of a SIP requirement, for all
States, the District of Columbia, and the U.S. Virgin Islands. Neither
the CAA nor the RHR require States to conduct an evaluation of
environmental justice when preparing a Haze SIP, although the EPA
encourages States to consider whether there may be equity and
environmental justice considerations when developing a Haze SIP. This
proposed rulemaking only proposes to extend the SIP deadline for the
third implementation period. It does not revise or impose new
requirements regarding the development of a Haze SIP. For these
reasons, the EPA believes that it is not practicable to assess whether
this action is likely to result in new disproportionate and adverse
effects on communities with environmental justice concerns. As was
explained in this action, the EPA provided for meaningful outreach and
engagement through the opening of a nonregulatory docket and receipt of
feedback, including feedback being considered as part of this proposed
rulemaking.

revision to EPA by July 31, 2021, July 31, 2031, July 31, 2038, and
every 10 years thereafter. The plan revision due on or before July 31,
2021, must include a commitment by the State to meet the requirements
of paragraph (g) of this section. In each plan revision, the State must
address regional haze in each mandatory Class I Federal area located
within the State and in each mandatory Class I Federal area located
outside the State that may be affected by emissions from within the
State. To meet the core requirements for regional haze for these areas,
the State must submit an implementation plan containing the following
plan elements and supporting documentation for all required analyses:
