RIN 2060-AU54
Implementation of the Revoked 1997 8-Hour Ozone National Ambient
Air Quality Standards; Updates to 40 CFR Part 52 for Areas That
Attained by the Attainment Date
AGENCY: Environmental Protection Agency (EPA)
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is updating part 52
of title 40, chapter 1 of the Code of Federal Regulations (CFR) to
codify its findings that nine areas in four states attained the revoked
1997 8-hour ozone National Ambient Air Quality Standards (herein
referred to as the 1997 ozone NAAQS) by the applicable attainment
dates. In February 2019, EPA Regional Offices sent letters to the
affected states to communicate the EPA's findings. The areas that
timely attained the standards include the Buffalo-Niagara Falls area,
and the Jefferson County, Poughkeepsie and Jamestown areas in the state
of New York; the Shoreline Sheboygan County and Inland Sheboygan County
areas in Wisconsin; the Denver-Boulder-Greeley-Ft. Collins-Loveland
area in Colorado; and the San Francisco Bay and Ventura County areas in
California. Publishing these determinations in part 52 will document
for the public and state air agencies that these areas attained the
standards by the applicable attainment dates and are therefore not
subject to anti-backsliding consequences for failure to timely attain
the standards.
DATES: The direct final rule is effective on January 7, 2021 without
further notice unless the EPA receives relevant adverse written
comments, or if a public hearing is requested by October 14, 2020, on
the proposed rule. In such case, refer to the General Information
section.

I. General Information
A. Why is EPA using a direct final rule?
The EPA is publishing this direct final rule without a prior
proposed rule because the agency views this as a noncontroversial
action. The EPA anticipates no adverse comment because this final
action codifies the EPA's factual findings that certain areas attained
the revoked 1997 ozone NAAQS by the applicable attainment dates. In the
``Proposed Rules'' section of this Federal Register, the EPA is
publishing the parallel proposed rule to update part 52. If adverse
comments are received on the proposed rule, the EPA will not institute
a second comment period on this action. Any parties interested in
commenting on the proposed rule must do so at this time. For further
information about commenting on the proposed rule, see the DATES and
ADDRESSES section of the proposed rule.
If the EPA receives relevant adverse comment on all or a distinct
portion of the proposed rule, the Agency will publish a timely
withdrawal in the Federal Register. The withdrawal notice will inform
the public of the direct final rule provisions that will become
effective and which provisions are being withdrawn. In the event the
EPA receives relevant adverse comment on the proposed rule, the EPA
will respond in writing to comments and include the written responses
in any subsequent final rule based on the proposed rule.
B. Does this action apply to me?
Publishing these determinations in part 52 will document for the
public and state air agencies that these areas factually attained the
revoked 1997 ozone NAAQS by the applicable attainment dates and are
therefore not subject to anti-backsliding consequences for failure to
timely attain the standards. The scope of the rule is narrow, and the
EPA had previously informed the affected states' air agencies of these
determinations by way of letter in February 2019. The direct final rule
will not create any new requirements for any affected state.
Nonetheless, the public is invited to comment on the proposed rule.
II. Background
On July 18, 1997, the EPA established standards for the 8-hour
average ozone concentrations at a level of 0.08 parts per million (ppm)
\1\ for both the primary and secondary NAAQS \2\ (herein referred to as
the 1997 ozone NAAQS).\3\ Subsequently, the EPA designated areas around
the country as either attaining (``attainment'') or not attaining
(``nonattainment'') the 1997 ozone NAAQS. Effective on June 15,
2004,\4\ the EPA established the nonattainment area designations,
classifications, and attainment dates \5\ that applied to the 1997
ozone NAAQS nonattainment areas, and included attainment dates for
Early Action Compact (EAC) areas.\6\ The EPA then issued a rule for
implementing the 1997 ozone NAAQS that was published in a separate
Federal Register notice effective on the same date, June 15, 2004.\7\
---------------------------------------------------------------------------
\1\ An area would violate the standard at a level greater than
0.084 ppm because rounding would cause a level of 0.085 ppm to be
interpreted as 0.09 ppm, which exceeds the 0.08 ppm standard.
\2\ Primary standards provide public health protection,
including protecting the health of ``sensitive'' populations such as
asthmatics, children, and the elderly. Secondary standards provide
public welfare protection, including protection against decreased
visibility and damage to animals, crops, vegetation, and buildings.

\5\ Ozone nonattainment area attainment dates are specific to
the areas' classifications (see 69 FR 23858, 23863, April 30, 2004).
\6\ To achieve clean air as soon as possible, the EPA worked
with certain communities that entered into EACs. The goal of these
Compacts was to help communities reduce ground-level ozone about 2
years sooner than required by the CAA. Accordingly, the EPA deferred
the 1997 ozone NAAQS effective attainment dates for EAC areas. While
these areas were violating the 8-hour standard, the EAC areas were
continuing to meet compact milestones towards clean air. (see 69 FR
23858, 23865, April 30, 2004)

---------------------------------------------------------------------------
Four years later, on March 27, 2008, the EPA revised the 8-hour
ozone standards to a more protective level of 0.075 ppm for both the
primary and secondary standards (herein referred to as the 2008 ozone
NAAQS) \8\ and issued implementing regulations for the revised NAAQS
(herein referred to as the 2008 ozone SIP Requirements Rule) \9\ in
April 2015. In that rule, the EPA revoked the 1997 ozone NAAQS and
established requirements to ensure that progress toward clean air in
those areas would not ``backslide.'' The EPA also stated that it would
no longer make determinations of attainment by the
[[Page 64048]]
attainment date except to trigger relevant anti-backsliding
obligations, as the designations and classifications for 1997 ozone
NAAQS areas were no longer in effect following revocation.
---------------------------------------------------------------------------

Subsequently, in South Coast Air Quality Management District v. EPA
(882 F.3d 1138 (D.C. Cir. 2018)) (known as the South Coast II
decision),\10\ the U.S. Circuit Court of Appeals for the District of
Columbia vacated, among other things, certain portions of the 2008
ozone SIP Requirements Rule, in part effectively re-establishing a
requirement for EPA to reclassify areas that failed to attain the
revoked 1997 ozone NAAQS by the area's applicable attainment date.\11\
The EPA does not interpret the South Coast II decision to compel the
Agency to issue determinations of attainment by the attainment date or
to make these updates to part 52 for areas that timely attained the
revoked 1997 ozone NAAQS. Rather the EPA views these discretionary
actions as helpful to clarify the status of the affected areas after
the court decision.
---------------------------------------------------------------------------
\10\ South Coast Air Quality Management District v. EPA, 882
F.3d 1138 (DC Cir. 2018). Available on the Court of Appeals D.C.

opinions.nsf/217B6778AE3EC89C8525823600532AE0/$file/15-1115-
1718293.pdf.
\11\ Attainment of the standard is established by calculating
the 8-hour ozone design values (DVs) using certified quality-assured
ozone air quality monitoring data available for the three full
calendar years prior to the attainment date applicable to each area,
where the standard would be attained at a level less than or equal
to 0.084 ppm.
---------------------------------------------------------------------------
To clarify the status of areas that attained the 1997 ozone NAAQS
by the applicable attainment dates, in February 2019, four EPA Regional
Offices issued letters to four states identifying nine areas that had
attained the standards by the applicable attainment
dates.12 13 14 15 The findings were based on certified
quality-assured air quality monitoring data from the 3 calendar years
preceding the respective attainment dates. This direct final rule
updates the regulations at 40 CFR part 52 to reflect these earlier
findings. The information contained in the letters is summarized in
Table 1,\16\ including the de sign values (DVs) for the applicable
attainment dates.\17\

\A\ The separate Inland Sheboygan County, Wisconsin and Shoreline Sheboygan County, Wisconsin, ozone
nonattainment areas were originally designated as a single, full-county area named Sheboygan County,
Wisconsin, covering the same geographic area. The EPA's February 8, 2019, finding of attainment by the
attainment date for the 1997 ozone NAAQS applied to the original full-county area. On July 15, 2019, the EPA
revised the original designation by splitting the full-county 1997 ozone area into two separate and distinct
areas (84 FR 33699, July 15, 2019). This change is reflected in 40 CFR 81.350 ``Wisconsin.'' at https://www.ecfr.gov/cgi-bin/text-idx?SID=0fd7171e7292313c1acf5280be3bdc6e&mc= true&node=sp40.20.81.c&rgn=div6 (see 84
FR 33699, July 15, 2019, at https://www.govinfo.gov/content/pkg/FR-2019-07-15/pdf/2019-14990.pdf and 40 CFR
81.350).
III. Summary of Final Action
This direct final rule updates the regulations at 40 CFR part 52 to
reflect the earlier findings of determinations of attainment by the
attainment date for the revoked 1997 ozone NAAQS. Publishing these
determinations in part 52 will document for the public and state air
agencies that these areas attained the standards by the applicable
attainment dates and are therefore not subject to anti-backsliding
consequences for failure to timely attain the standards.
IV. Environmental Justice Considerations
This direct final rule requires no environmental justice
considerations.
V. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review
This action is not a significant regulatory action and, therefore,
was not
[[Page 64049]]
submitted to the Office of Management and Budget for review.
B. Executive Order 13771: Reducing Regulations and Controlling
Regulatory Costs
This action is not an Executive Order 13771 regulatory action
because this action is not a significant regulatory action under
Executive Order 12866.
C. Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under
the PRA.
D. Regulatory Flexibility Act (RFA)
I certify that 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.
E. Unfunded Mandates Reform Act (UMRA)
This action does not contain any unfunded mandate or significantly
or uniquely affect small governments, as described in the Unfunded
Mandates Reform Act of 1995, 2 U.S.C. 1531-1538.\18\ The action imposes
no enforceable duty on any state, local or tribal governments or the
private sector.
---------------------------------------------------------------------------
\18\ U.S.C. is United States Code.
---------------------------------------------------------------------------
F. 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.
G. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
This action does not have tribal implications as specified in
Executive Order 13175. This action will neither impose substantial
direct compliance costs on federally recognized tribal governments, nor
preempt tribal law. Thus, Executive Order 13175 does not apply to this
action.
H. Executive Order 13045: Protection of Children From Environmental
Health and 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. This action is not subject to
Executive Order 13045 because it does not concern an environmental
health risk or safety risk.
I. 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.
J. National Technology Transfer Advancement Act (NTTAA)
This rulemaking does not involve technical standards.
K. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations
The EPA believes that this action does not have disproportionately
high and adverse human health or environmental effects on minority,
low-income populations and/or indigenous peoples, as specified in
Executive Order 12898 (see 59 FR 7629, February 16, 1994). The
documentation for this decision is contained in Section IV of this
document titled, ``Environmental Justice Considerations.''
L. Congressional Review Act (CRA)
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).
M. Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review
of final actions that are locally and regionally applicable may be
filed only in the United States Court of Appeals for the appropriate
circuit by December 8, 2020. However, the statute also provides that
notwithstanding that general rule, ``a petition for review of any
action . . . may be filed only in the United States Court of Appeals
for the District of Columbia if such action is based on a determination
of nationwide scope or effect and if in taking such action the
Administrator finds and publishes that such action is based on such a
determination.'' Because this final action makes findings regarding the
attainment status of areas across the country, in multiple EPA regions
and within the jurisdictions over multiple U.S. Circuit Courts of
Appeal, the Administrator finds that this action has nationwide scope
and effect. Therefore, in accordance with CAA section 307(b)(1),
petitions for review of this final action may be filed only in the
United States Court of Appeals for the District of Columbia Circuit.
Under CAA section 307(b)(2), the requirements established by this final
rule may not be challenged separately in any civil or criminal
proceedings for enforcement.

December 8, 2020, the EPA determined that the Shoreline Sheboygan
County, Wisconsin, and the Inland Sheboygan County, Wisconsin, Moderate
ozone nonattainment areas attained the revoked 1997 8-hour ozone
National Ambient Air Quality Standards (NAAQS) by the applicable
attainment date of June 15, 2010. The determinations are based upon
complete quality-assured and certified data for the three calendar
years 2007-2009. Together, the separate Shoreline Sheboygan County,
Wisconsin, and the Inland Sheboygan County, Wisconsin, areas encompass
the identical geographic area of the original full-county Sheboygan
County, Wisconsin, area. The EPA's initial February 8, 2019,
