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.

ADDRESSES: The EPA established Docket ID No. EPA-HQ-OAR-2019-0611 for 
this action. All documents on the docket are listed at https://www.regulations.gov. Although listed in the docket index, some

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.

June 15, 2004. Available on the U.S. GPO website at https://www.govinfo.gov/content/pkg/FR-2004-04-30/pdf/04-9152.pdf.
    \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.

Quality Standards for Ozone'' final rule effective May 27, 2008.

    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.

F.3d 1138 (DC Cir. 2018). Available on the Court of Appeals D.C.

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.
