Designation of Areas for Air Quality Planning Purposes; 
California; Eastern Kern, Sacramento Metro, and Western Nevada 2015 
Ozone Nonattainment Areas; Reclassification to Serious

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Under the Clean Air Act (CAA), the Environmental Protection 
Agency (EPA) is proposing to grant requests by the California Air 
Resources Board (CARB) to reclassify three nonattainment areas in 
California from ``Moderate'' to ``Serious'' for the 2015 ozone national 
ambient air quality standards (NAAQS). These three areas are herein 
referred to as the Eastern Kern, Sacramento Metro, and Western Nevada 
nonattainment areas. In connection with the reclassification, the EPA 
is proposing to establish deadlines for submittal of revisions to the 
Eastern Kern, Sacramento Metro, and Western Nevada portions of the 
California state implementation plan (SIP) to meet additional 
requirements for Serious ozone nonattainment areas.

I. Background

    The CAA requires the EPA to establish primary and secondary NAAQS 
for certain pervasive pollutants that ``may reasonably be anticipated 
to endanger public health and welfare.'' The primary NAAQS is designed 
to protect public health with an adequate margin of safety, and the 
secondary NAAQS is designed to protect public welfare and the 
environment. The EPA has set NAAQS for six common air pollutants, 
referred to as criteria pollutants, including ozone. The NAAQS 
represent the air quality levels an area must meet to comply with the 
CAA. Ozone is a gas composed of three oxygen atoms and is created by 
chemical reactions between volatile organic compounds (VOC) and oxides 
of nitrogen (NO<INF>X</INF>) in the atmosphere in the presence of 
sunlight. Ground-level ozone can harm human health and the environment. 
Ozone exposure has been associated with increases in susceptibility to 
respiratory infections, medication use by asthmatics, doctor visits, 
and emergency department visits and hospital admissions for individuals 
with respiratory disease. Ozone exposure may also contribute to 
premature death, especially in people with heart and lung disease.
    In October 2015, the EPA strengthened the primary and secondary 
eight-hour ozone NAAQS from 0.075 parts per million (ppm) to 0.070 ppm 
(``2015 ozone NAAQS'').\1\ In accordance with section 107(d) of the 
CAA, the EPA must designate an area ``nonattainment'' if it is 
violating the NAAQS or if it is contributing to a violation of the 
NAAQS in a nearby area. With respect to the ozone NAAQS, the EPA 
further classifies nonattainment areas as ``Marginal,'' ``Moderate,'' 
``Serious,'' ``Severe,'' or ``Extreme,'' depending upon the ozone 
design value for an area.\2\ As a general matter, higher classified 
ozone nonattainment areas are subject to a greater number of, and more 
stringent, CAA planning requirements than lower classified areas but 
are allowed more time to demonstrate attainment of the ozone NAAQS.\3\
---------------------------------------------------------------------------

    \1\ 80 FR 65291 (October 26, 2015).
    \2\ See CAA section 181(a)(1). For the 2015 ozone NAAQS, the 
design value at each monitoring site is the annual fourth-highest 
daily maximum 8-hour average ozone concentration, averaged over 
three years. The design value for an area is the highest design 
value among the monitoring sites in the area.
    \3\ See, generally, subpart 2 of part D of title I of the CAA.
---------------------------------------------------------------------------

    Effective August 3, 2018, the EPA designated and classified the 
Eastern

[[Page 44678]]

Kern,\4\ Sacramento Metro,\5\ and Western Nevada \6\ areas under the 
CAA as Moderate nonattainment for the 2015 ozone NAAQS.\7\ The EPA's 
classification of these areas as Moderate ozone nonattainment 
established a requirement that each area attain the 2015 ozone NAAQS as 
expeditiously as practicable, but no later than six years from the date 
of designation as nonattainment, i.e., August 3, 2024.\8\
---------------------------------------------------------------------------

    \4\ Kern County is located in the southernmost portion of 
California's Central Valley. The Eastern Kern ozone nonattainment 
area, which lies within the Mojave Desert air basin, covers the 
eastern portion of Kern County, excluding Indian Wells Valley. The 
western portion of Kern County lies within the San Joaquin Valley 
air basin and is included within the San Joaquin Valley ozone 
nonattainment area. For more detail on the boundaries of the Eastern 
Kern ozone nonattainment area, see the entry for ``Kern County 
(Eastern Kern), CA'' in the 2015 ozone table in 40 CFR 81.305.
    \5\ The Sacramento Metro nonattainment area includes Sacramento 
and Yolo Counties, the eastern portion of Solano County, the western 
portions of Placer and El Dorado counties outside of the Lake Tahoe 
Basin, and the southern portion of Sutter County. For more detail on 
the boundaries of the Sacramento Metro ozone nonattainment area, see 
the entry for ``Sacramento Metro, CA'' in the 2015 ozone table in 40 
CFR 81.305.
    \6\ Nevada County is located in the north-central Sierra Nevada 
Range and includes portions of Tahoe National Forest. The 
easternmost portion of Nevada County is excluded from the Western 
Nevada ozone nonattainment area and is designated unclassified or 
attainment for the 2015 ozone NAAQS. For more detail on the 
boundaries of the Western Nevada ozone nonattainment area, see the 
entry for ``Nevada County (Western part), CA'' in the 2015 ozone 
table in 40 CFR 81.305.

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

    In August 2020, CARB submitted to the EPA a request from the air 
districts in the Sacramento Metro area \9\ to voluntarily reclassify 
the Sacramento Metro ozone nonattainment area from Moderate to Serious 
nonattainment for the 2015 ozone NAAQS.\10\ In May 2021, CARB submitted 
to the EPA requests from the Eastern Kern Air Pollution Control 
District and the Northern Sierra Air Quality Management District to 
voluntarily reclassify the Eastern Kern and Western Nevada ozone 
nonattainment areas, respectively, from Moderate to Serious 
nonattainment for the 2015 ozone NAAQS.\11\ In this document, we refer 
to the air districts in the Sacramento Metro, Eastern Kern, and Western 
Nevada nonattainment areas collectively as the ``districts.'' Under the 
EPA's ozone implementation rules at 40 CFR 51.1303(b), the EPA must 
approve a state's request, for any reason, for a higher classification 
for an ozone nonattainment area, in accordance with CAA section 
181(b)(3).\12\ We find that the plain language of CAA section 181(b)(3) 
and 40 CFR 51.1303(b) mandates that we approve these voluntary 
reclassification requests, and thus, the EPA proposes in this action to 
grant CARB's request to reclassify the Eastern Kern, Sacramento Metro, 
and Western Nevada nonattainment areas from Moderate to Serious for the 
2015 ozone NAAQS.
---------------------------------------------------------------------------

    \9\ The Sacramento Metro area is regulated by five local air 
districts: The Sacramento Metropolitan Air Quality Management 
District (AQMD), the Feather River AQMD, the El Dorado County AQMD, 
the Yolo-Solano AQMD, and the Placer County Air Pollution Control 
District.
    \10\ Letter dated August 3, 2020, from Richard W. Corey, 
Executive Officer, CARB, to John Busterud, Regional Administrator, 
EPA Region IX, requesting voluntary reclassification of Sacramento 
Metro to Serious nonattainment for the 2015 ozone NAAQS.
    \11\ Letters, dated April 30, 2021 and May 15, 2021, from 
Richard W. Corey, Executive Officer, CARB, to Deborah Jordan, Acting 
Regional Administrator, EPA Region IX, requesting voluntary 
reclassification of Western Nevada and Eastern Kern to Serious 
nonattainment for the 2015 ozone NAAQS, respectively.
    \12\ CAA section 181(b)(3) provides that the EPA shall grant the 
request of any state to reclassify an ozone nonattainment area to a 
higher classification.
---------------------------------------------------------------------------

II. Serious Area Requirements and Proposed Schedule

    In this action, we are proposing to reclassify the Eastern Kern, 
Sacramento Metro, and Western Nevada nonattainment areas from Moderate 
to Serious for the 2015 ozone NAAQS. We are also proposing to establish 
a schedule for the State to submit SIP revisions to address the 
planning requirements made applicable to each area as a result of its 
higher classification, including both the general air quality planning 
requirements under CAA section 172(c) and the specific requirements for 
Serious areas under CAA section 182(c), as interpreted and described in 
the final SIP Requirements Rule for the 2015 ozone NAAQS (``2015 Ozone 
SRR'').\13\ Deadlines for the submittal of specific planning elements 
are described in Section II of this notice. Upon the effective date of 
a final action granting the reclassification, the areas would be 
required to attain the 2015 ozone NAAQS as expeditiously as 
practicable, but no later than nine years from the effective date of 
designation as nonattainment, i.e., no later than August 3, 2027.
---------------------------------------------------------------------------

    \13\ The EPA promulgated the 2015 Ozone SRR at 40 CFR part 51, 
subpart CC.
---------------------------------------------------------------------------

A. Serious Area Plan Requirements in General

    The 2015 Ozone SRR requires states to submit a SIP revision 
including a Serious area attainment demonstration, reasonable further 
progress demonstration, reasonably available control measures, and 
contingency measures for the 2015 ozone NAAQS no later than four years 
from the area's date of designation as nonattainment.\14\ Additionally, 
for the Sacramento area, California would be required to certify that 
its current motor vehicle inspection and maintenance (I/M) program 
meets the requirements for an enhanced I/M program as required by the 
CAA and the EPA's I/M regulations.\15\ CARB would also need to either 
submit a SIP revision that addresses the CAA's requirements for a clean 
fuel vehicle program or certify that that its currently approved 
substitute measure continues to meet CAA requirements.\16\ Neither 
Eastern Kern nor Western Nevada meet the minimum population-based 
applicability thresholds for the enhanced I/M and clean fuel vehicle 
program requirements.\17\ We are proposing not to alter the four-year 
schedule for submittal of Serious area SIP revisions under the 2015 
Ozone SRR. Therefore, following the EPA's final reclassification of 
Eastern Kern, Sacramento Metro, and Western Nevada to Serious ozone 
nonattainment, CARB would be required to submit a SIP revision 
addressing the Serious area elements listed in this section by August 
3, 2022 (i.e., four years from the areas' designation as 
nonattainment).
---------------------------------------------------------------------------

    \14\ See CAA section 182(c) and 83 FR 62988. We encourage CARB 
and the districts to work with EPA Region IX staff to confirm the 
specific planning requirements applicable to each area.
    \15\ CAA section 182(c)(3) and 40 CFR part 51 subpart S.
    \16\ CAA sections 182(c)(4) and 246(a).
    \17\ CAA section 182(c)(3)(A) and 246(a), respectively.
---------------------------------------------------------------------------

B. New Source Review and Title V Program Revisions

    Typically, when we reclassify an area to a higher ozone 
classification, the state must amend its new source review (NSR) rules 
for the area to reflect the lower NSR major source threshold, lower 
major modification threshold (as applicable), and higher NSR offset 
ratio corresponding to the higher classification. Under CAA 182(c), the 
major source threshold for areas reclassified from Moderate to Serious 
is lowered from 100 tons per year (tpy) to 50 tpy. Under the EPA's NSR 
regulations, the significant emissions rates that define major 
modifications for NO<INF>X</INF> and VOC in areas reclassified from 
Moderate to Serious are lowered from 40 tpy to 25 tpy.\18\ Under CAA 
section 182(c)(10), the VOC and NO<INF>X</INF> offset ratios for major 
sources and modifications in a Serious nonattainment area must be at 
least 1.2 to 1. Reclassification to Serious ozone nonattainment would 
typically also

[[Page 44679]]

require changes to the districts' title V operating permits programs 
necessary to reflect the change in the major source threshold for 
Serious areas.
---------------------------------------------------------------------------

    \18\ 40 CFR 51.165(a)(1)(x).
---------------------------------------------------------------------------

    The Eastern Kern and Western Nevada ozone nonattainment areas are 
currently classified as Serious for the 2008 ozone NAAQS and therefore 
are currently subject to the lower major source and major modification 
thresholds and higher offset ratios applicable to Serious ozone 
nonattainment areas. The Sacramento Metro nonattainment area is 
classified as Severe for the 2008 ozone NAAQS and is therefore subject 
to the more stringent major source and major modification thresholds 
and offset ratio applicable to Severe ozone nonattainment areas. For 
this reason, we anticipate that reclassification to Serious for the 
2015 ozone NAAQS will not require the districts to amend their NSR 
rules to incorporate the requirements for Serious nonattainment areas 
and that the districts may therefore satisfy the applicable NSR 
requirements by certifying that their current NSR programs address 
Serious area requirements.
    We are proposing under our general CAA section 301(a) authority to 
establish a deadline of August 3, 2022, for the State to submit, for 
each area, revised NSR rules or a certification that the area's current 
NSR program is sufficient to meet the applicable requirements. We are 
also proposing under CAA section 301(a) to establish a deadline of 
August 3, 2022, for each area to submit revised title V program rules 
reflecting the Serious area major source definition. Given the narrow 
scope of the required revisions, we anticipate a deadline of August 3, 
2022, will allow the districts sufficient time to make the required 
changes without imposing a lengthy delay in the requirement for sources 
newly subject to the title V program to submit a timely 
application.\19\ Additionally, this date is the same as the submittal 
due date for other Serious area elements and will allow the districts 
to submit any NSR and title V revisions together with these other 
elements.
---------------------------------------------------------------------------

    \19\ A source newly subject to the title V permit program is 
required to submit a title V application within 12 months after the 
source becomes subject to the program. See 40 CFR 70.5(a)(1)(i).
---------------------------------------------------------------------------

C. Reasonably Available Control Technology

    Ozone nonattainment areas classified as Moderate and above are 
required to implement reasonably available control technology (RACT) 
for major sources.\20\ Major sources are defined for Moderate areas as 
sources that emit or have the potential to emit 100 tpy of VOC or 
NO<INF>X</INF>.\21\ For Serious areas reclassified from Moderate, the 
requirement for RACT expands to include all sources that emit, or have 
the potential to emit, 50 tpy of VOC or NO<INF>X</INF>.\22\ Thus, 
following reclassification from Moderate to Serious, states must revise 
their RACT SIPs to include those other sources emitting or having the 
potential to emit between 50 and 100 tpy. Under 40 CFR 
51.1312(a)(2)(ii), RACT SIP submittals are due 24 months from the 
effective date of reclassification or a deadline otherwise established 
by the EPA in the reclassification action. Under 40 CFR 
51.1312(a)(3)(ii), RACT requirements triggered by reclassification 
should be implemented as expeditiously as practicable, but no later 
than the start of the attainment year ozone season associated with the 
area's new attainment deadline, or January 1 of the third year after 
the associated SIP revision submittal deadline, whichever is earlier; 
or by a deadline otherwise established by the EPA.
---------------------------------------------------------------------------

    \20\ CAA sections 182(b)(2) and 182(f).
    \21\ CAA section 302(j).
    \22\ CAA sections 182(c) and 182(f).
---------------------------------------------------------------------------

    Consistent with 40 CFR 51.1312(a)(2)(ii), we are proposing to 
establish a deadline of 24 months from the effective date of 
reclassification to Serious for Eastern Kern, Sacramento Metro, and 
Western Nevada to submit a Serious area RACT SIP. Consistent with 40 
CFR 51.1312(a)(3)(ii), we are proposing a deadline for implementation 
of Serious area RACT rules as expeditiously as practicable but no later 
than the start of the attainment year ozone season associated with the 
affected areas' new attainment date (i.e., January 1, 2027, as 
proposed) \23\ or January 1 of the third year after the affected areas' 
Serious area RACT SIP submittal deadline,\24\ whichever is earlier. 
Eastern Kern, Sacramento Metro, and Western Nevada each remain subject 
to the Moderate area RACT implementation deadline of January 1, 2023, 
under 40 CFR 51.1312(a)(3)(i).
---------------------------------------------------------------------------

    \23\ Because ozone nonattainment areas in California have a 
year-round ozone season, the start of the attainment year ozone 
season associated with each area's new attainment date would be 
January 1, 2027.
    \24\ If the EPA issues a final reclassification action that is 
effective in calendar year 2021, January 1 of the third year after 
the RACT SIP submittal deadline would be January 1, 2026.
---------------------------------------------------------------------------

D. Transportation Control

    CAA section 182(c)(5) requires ozone nonattainment areas that are 
classified as Serious to submit a demonstration as to whether current 
aggregate vehicle mileage, aggregate vehicle emissions, congestion 
levels, and other relevant parameters are consistent with those used 
for the area's demonstration of attainment. The CAA requires the first 
report to be submitted 6 years after November 15, 1990, which is two 
years after the deadline for Serious area attainment demonstrations, 
and every three years thereafter.\25\ Consistent with this schedule, we 
are proposing that the first report be submitted 24 months after the 
attainment demonstrations for these areas are due (i.e., August 3, 
2024) and every three years thereafter. If a demonstration shows that 
such parameters and emissions levels exceed the levels projected for 
purposes of the area's attainment demonstration, the State would be 
required to develop and submit a SIP revision within 18 months that 
includes transportation control measures to reduce emissions to levels 
that are consistent with those projected in the demonstration.\26\

    \25\ CAA section 182(c)(2).
    \26\ CAA section 182(c)(5).
---------------------------------------------------------------------------

III. Reclassification of Areas of Indian Country

    Because the State of California does not have jurisdiction over 
Indian country geographically located within the borders of the state, 
CARB's reclassification requests do not apply to the areas of Indian 
country within the boundaries of the nonattainment areas identified in 
40 CFR 81.305. In these areas of Indian country, the EPA implements 
federal CAA programs, including reclassifications, consistent with our 
discretionary authority under sections 301(a) and 301(d)(4) of the CAA. 
There are no tribal lands located within the boundaries of the Eastern 
Kern and Western Nevada ozone nonattainment areas. The Sacramento Metro 
ozone nonattainment area includes lands of four federally recognized 
tribes: The Shingle Springs Band of Miwok Indians, Shingle Springs 
Rancheria (Verona Tract); the United Auburn Indian Community of the 
Auburn Rancheria of California; the Wilton Rancheria; and the Yocha 
Dehe Wintun Nation.
    The EPA contacted tribal officials from each of the federally 
recognized tribes having jurisdiction over lands within the boundaries 
of the Sacramento Metro ozone nonattainment area to invite government-
to-government consultation on this rulemaking. Under the EPA's 
Consultation Policy, the EPA consults on a government-to-government 
basis with federally recognized tribal governments when the EPA's 
actions and decisions may affect tribal interests.

[[Page 44680]]

No tribes requested government-to-government consultation on this 
action.
    We have considered the relevance of our proposal to reclassify the 
Sacramento Metro area as Serious nonattainment for the 2015 ozone NAAQS 
for each tribe located within the Sacramento Metro area. We believe 
that the same facts and circumstances that support the proposal for the 
non-Indian country lands also support the proposal for reservation 
areas of Indian country and any other areas of Indian country where the 
EPA or a tribe has demonstrated that the tribe has jurisdiction located 
within the Sacramento Metro area. In this particular case, the State's 
reclassification request is based on modeling results that show that a 
longer timeframe is necessary to attain the 2015 ozone NAAQS for the 
Sacramento Metro area. The longer timeframes will provide the time 
necessary to realize full implementation of the stationary and mobile 
source regulations contained in the districts' attainment plans. 
Additionally, uniformity of classification throughout a nonattainment 
area is a guiding principle and premise when an area is being 
reclassified. Ozone and ozone precursors are pervasive pollutants that 
can be transported throughout a nonattainment area. Therefore, 
boundaries for nonattainment areas are drawn to encompass both areas 
with direct sources of pollution as well as nearby areas in the same 
airshed in which ozone can be transported. Each nonattainment area is 
assigned an initial classification that applies consistently within the 
boundaries of the area. The EPA believes this approach best ensures 
public health protection from the adverse effects of ozone pollution. 
Therefore, it is generally counterproductive from an air quality and 
planning perspective to have a different classification for a land area 
located within the boundaries of a nonattainment area, such as the 
areas of Indian country in the Sacramento Metro ozone nonattainment 
area. Accordingly, based on the EPA's discretionary authority under 
sections 301(a) and 301(d)(4) of the CAA to implement federal CAA 
programs in these areas of Indian country, including reclassifications, 
the EPA is proposing to reclassify areas of Indian country 
geographically located in the Sacramento Metro area to Serious 
nonattainment for the 2015 ozone NAAQS.
    The Sacramento Metro area and the tribes located within its 
boundaries are currently designated as Severe, i.e., one classification 
higher than Serious, for the 1997 and 2008 ozone NAAQS. An area's 
applicable major source thresholds and offset ratios for NSR and title 
V programs are based on the area's highest ozone classification. 
Because these areas of Indian country are already classified as a 
higher classification for the 1997 and 2008 ozone NAAQS, the major 
source thresholds and offset ratios for NSR and title V programs 
applicable to the tribes in the Sacramento Metro area will not change. 
This reclassification also will not affect projects proposed in these 
areas of Indian country that require federal permits, approvals, or 
funding under the EPA's general conformity rule because such projects 
are already subject to the de minimis thresholds and offset ratios for 
Severe ozone nonattainment areas. We note that, while eligible tribes 
may seek EPA approval of relevant tribal programs under the CAA, none 
of the affected tribes would be required to submit an implementation 
plan as a result of this reclassification.
    In light of the considerations outlined in this notice that support 
retention of a uniformly-classified ozone nonattainment area and our 
proposal to approve the State's voluntary reclassification request, we 
propose to reclassify the entire Sacramento Metro nonattainment area, 
including reservation areas of Indian country and any other area of 
Indian country located within it where the EPA or a tribe has 
demonstrated that the tribe has jurisdiction, as Serious nonattainment 
for the 2015 ozone NAAQS. The EPA specifically solicits additional 
comment on this proposed rule from tribal officials.

IV. Proposed Action and Request for Public Comment

    Pursuant to CAA section 181(b)(3), we are proposing to grant CARB's 
request to reclassify the Eastern Kern, Sacramento Metro, and Western 
Nevada ozone nonattainment areas from Moderate to Serious for the 2015 
ozone NAAQS. As described in Section III of this notice, our proposal 
to reclassify Sacramento Metro to Serious for the 2015 ozone NAAQS 
includes reservation areas of Indian country and any other area of 
Indian country located within it where the EPA or a tribe has 
demonstrated that the tribe has jurisdiction.
    As described in Section II of this document, the EPA is proposing a 
schedule for the State and districts to submit SIP revisions addressing 
Serious area requirements and to submit revisions to the title V 
operating permit rules for Eastern Kern, Sacramento Metro, and Western 
Nevada. Under the EPA's proposed schedule, California would be required 
to submit SIP revisions addressing Serious area requirements for the 
affected areas, including an attainment demonstration, reasonable 
further progress demonstration, reasonably available control measures, 
contingency measures, motor vehicle I/M program, and clean fuel vehicle 
program, as applicable, by August 3, 2022. Submittal of any 
corresponding revisions to NSR and title V program rules that apply in 
the affected areas would also be due by August 3, 2022. A SIP revision 
including Serious area RACT rules for the affected areas would be due 
24 months from the effective date of the reclassification. Lastly, the 
EPA is proposing a deadline for implementation of Serious area RACT 
rules as expeditiously as practicable but no later than the start of 
the attainment year ozone season associated with the affected areas' 
new attainment date or January 1 of the third year after the affected 
areas' Serious area RACT SIP submittal deadline, whichever is earlier. 
We will accept comments from the public on this proposed rule for the 
next 30 days. The deadline and instructions for submission of comments 
are provided in the DATES and ADDRESSES sections at the beginning of 
this preamble.

V. Statutory and Executive Order Reviews

    Under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 
13563 (76 FR 3821, January 21, 2011), this proposed action is not a 
``significant regulatory action'' and therefore is not subject to 
Executive Order 12866. With respect to lands under state jurisdiction, 
voluntary reclassifications under CAA section 181(b)(3) are based 
solely upon requests by the state, and the EPA is required under the 
CAA to grant them. These actions do not, in and of themselves, impose 
any new requirements on any sectors of the economy. In addition, 
because the statutory requirements are clearly defined with respect to 
the differently classified areas, and because those requirements are 
automatically triggered by reclassification, reclassification does not 
impose a materially adverse impact under Executive Order 12866. For 
these reasons, this proposed action is also not subject to Executive 
Order 13211, ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001).
    In addition, I certify that this proposed rule will not have a 
significant economic impact on a substantial number of small entities 
under the

[[Page 44681]]

Regulatory Flexibility Act (5 U.S.C. 601 et seq.) and that this 
proposed rule 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), because the EPA is 
required to grant requests by states for voluntary reclassifications, 
and such reclassifications in and of themselves do not impose any 
federal intergovernmental mandate, and because tribes are not subject 
to implementation plan submittal deadlines that apply to states as a 
result of reclassifications.
    Executive Order 13175 (65 FR 67249, November 9, 2000) requires the 
EPA to develop an accountable process to ensure ``meaningful and timely 
input by tribal officials in the development of regulatory policies 
that have tribal implications.'' ``Policies that have tribal 
implications'' is defined in Executive Order 13175 to include 
regulations that have ``substantial direct effects on one or more 
Indian tribes, on the relationship between the federal government and 
Indian tribes, or on the distribution of power and responsibilities 
between the federal government and Indian tribes.'' Four Indian tribes 
have areas of Indian country located within the boundaries of the 
Sacramento Metro ozone nonattainment area, and there are no areas of 
Indian country located in the Eastern Kern and Western Nevada ozone 
nonattainment areas. The EPA implements federal CAA programs, including 
reclassifications, in these areas of Indian country within the 
boundaries of the Sacramento Metro area, consistent with our 
discretionary authority under sections 301(a) and 301(d)(4) of the CAA. 
The EPA has concluded that this proposed rule might have tribal 
implications for the purposes of Executive Order 13175 but would not 
impose substantial direct costs upon the tribes, nor would it preempt 
Tribal law. As discussed in Section III of this document, this proposed 
rule does not affect the implementation of NSR or title V programs in 
these areas of Indian country, nor does it affect projects proposed in 
these areas of Indian country that require federal permits, approvals, 
or funding under the EPA's general conformity rule. None of the 
affected tribes would be required to submit an implementation plan as a 
result of this reclassification.
    The EPA contacted tribal officials early in the process of 
developing this proposed rule to provide an opportunity to have 
meaningful and timely input into its development. On December 11, 2020, 
we sent letters to leaders of the four tribal governments representing 
the areas of Indian country in the nonattainment area offering 
government-to-government consultation and seeking input on how we could 
best communicate with the tribes on this rulemaking effort. No tribes 
requested government-to-government consultation on this action.
    Executive Order 12898 establishes federal executive policy on 
environmental justice. Its main provision directs federal agencies, to 
the greatest extent practicable and permitted by law, to make 
environmental justice part of their mission by identifying and 
addressing, as appropriate, disproportionately high and adverse human 
health or environmental effects of their programs, policies, and 
activities on minority populations and low-income populations in the 
United States. This reclassification action does not provide the EPA 
with the discretionary authority to address disproportionate human 
health or environmental effects with practical, appropriate, and 
legally permissible methods under Executive Order 12898.
    This proposed action also does not have federalism implications 
because it does not have substantial direct effects on the states, on 
the relationship between the national government and the states, nor on 
the distribution of power and responsibilities among the various levels 
of government, as specified in Executive Order 13132 (64 FR 43255, 
August 10, 1999). This proposed action does not alter the relationship 
or the distribution of power and responsibilities established in the 
CAA.
    This proposed rule also is not subject to Executive Order 13045, 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997), because the EPA interprets 
Executive Order 13045 as applying only to those regulatory actions that 
concern health or safety risks, such that the analysis required under 
section 5-501 of Executive Order 13045 has the potential to influence 
the regulation.
    As this proposal would set a deadline for the submittal of CAA 
required plans and information, the requirements of section 12(d) of 
the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 
272 note) do not apply. This proposed rule does not impose an 
information collection burden under the provisions of the Paperwork 
Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
