40 CFR Part 81
Identification of Ozone Areas Attaining the 1-Hour Standard and to
Which the 1-Hour Standard is No Longer Applicable; Final and Proposed
Rules
[[Page 2726]]
ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 81
[FRL-5945-7]
Identification of Ozone Areas Attaining the 1-Hour Standard and
to Which the 1-Hour Standard Is No Longer Applicable
AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule.
-----------------------------------------------------------------------
SUMMARY: The EPA is taking action today to identify ozone areas where
the 1-hour standard is no longer applicable. Therefore, the 40 CFR part
81 for ozone is being amended to reflect such changes. Today's
regulation is being published in direct response to the President's
memorandum of July 16, 1997. The President's memo directed EPA to
publish within 90 days an action identifying ozone areas to which the
1-hour standard will cease to apply because they have not measured a
current violation of the 1-hour standard. For all other areas, the 1-
hour standard will continue to apply. Furthermore, this action is being
done to assist in the phasing-out of the 1-hour standard since the
recently promulgated new 8-hour standard is now in effect and is more
protective of public health than the 1-hour ozone standard. The goal is
to move toward implementation of the new 8-hour standard. Following
today's action, the Agency intends to publish, in early 1998, a
subsequent document which takes similar action to revoke the 1-hour
standard in additional areas that have air quality that does not
violate the 1-hour standard. Furthermore, the Agency will publish, on
an annual basis, similar actions identifying areas where the 1-hour
standard is no longer applicable.
DATES: This regulation will become effective on March 17, 1998 unless
adverse comments are received during the public comment period. Written
comments on this rulemaking must be limited to addressing the technical
correctness of these determinations. All comments must be received on
or before February 17, 1998. If adverse comments are timely received on
any provision of the direct final rule, that provision will be
withdrawn and only those provisions on which no such adverse comments
are received will become effective on March 17, 1998.

I. Background
On November 6, 1991, the Agency issued a rulemaking (56 FR 56694)
which set forth the attainment status, including designations and
classifications, for selected areas affected by ozone, carbon monoxide,
particulate matter, and lead national ambient air quality standards
(NAAQS). That rulemaking established on a State-by-State, pollutant-by-
pollutant basis, the attainment status of the above-mentioned NAAQS.
Such air quality data used in the determinations for the rulemaking
were submitted by the appropriate States; the data were approved and
the areas were then designated and classified by the EPA. Subsequent to
the November 6, 1991 action, on November 30, 1992, the Agency issued
corrections (57 FR 56762) to the tables for some of the designations,
boundaries, and classifications as provided for under section 110(k)(6)
of the Clean Air Act (CAA).
Under the CAA, designations can be changed if sufficient data are
available to warrant such changes and if certain other requirements are
met (see CAA section 107(d)(3)(D)). Section 107(d)(3)(E) of the CAA
provides that the Administrator may promulgate a redesignation of a
nonattainment area to attainment if certain criteria are met. Such has
been the case for several ozone nonattainment areas which have been
redesignated to attainment over the
[[Page 2727]]
course of years following the CAA Amendments of 1990. The Agency has
promulgated these redesignations to attainment in the Federal Register
and thus has amended 40 CFR parts 52 and 81 accordingly.
On July 16, 1997, the President issued a memorandum (62 FR 38421,
July 18, 1997) to the Administrator of the EPA which indicates that
within 90 days of promulgation of the new 8-hour standard, the EPA will
publish an action identifying ozone areas to which the 1-hour standard
will cease to apply. The memorandum states that for areas where the air
quality does not currently attain the 1-hour standard, the 1-hour
standard will continue in effect. The provisions of subpart 2 of title
I of the CAA would also apply to currently designated nonattainment
areas until such time as each area has air quality meeting the 1-hour
standard.
On July 18, 1997 (62 FR 38856), EPA promulgated a regulation
replacing the 1-hour ozone standard with an 8-hour standard at a level
of 0.08 parts per million (ppm). The form of the 8-hour standard is
based on the 3-year average of the annual fourth-highest daily maximum
8-hour average ozone concentrations measured at each monitor within an
area. The new primary standard which became effective on September 16,
1997 will provide increased protection to the public, especially
children and other at-risk populations. On July 18, 1997, EPA also
announced that revocation of the 1-hour ozone NAAQS would be delayed
until areas achieved attainment of the 1-hour NAAQS. This was done in
order to facilitate continuity in public health protection during the
transition to the new NAAQS.
II. Summary of Today's Action
The purpose of this document is to revoke the 1-hour standard in
those areas that EPA has determined are not violating the 1-hour
standard. For all other areas the 1-hour standard will continue in
effect. The purpose of retaining the current standard for such areas is
to ensure a smooth transition to the new standard. When the areas not
meeting the 1-hour standard have air quality that meets the 1-hour
standard, as determined by EPA, then the Agency will likewise revoke
the 1-hour standard for such areas.
In the immediate future, the Agency intends to issue guidance
regarding the regulatory implications of today's action (revoking the
1-hour standard) as related to those areas where the 1-hour standard is
no longer applicable.
III. Analysis of Air Quality Data
This action, revoking the 1-hour standard in selected areas, is
based upon analysis of quality-assured, ambient air quality monitoring
data showing no violations of the 1-hour ozone standard. The method for
determining attainment of the ozone NAAQS is contained in 40 CFR part
50.9 and Appendix H to that section. The level of the 1-hour primary
and secondary NAAQS for ozone is 0.12 ppm.
The 1-hour standard no longer applies to an area once EPA
determines that the area has air quality not violating the 1-hour
standard. Determinations for this notice were based upon the most
recent data available, generally 1994-1996 data. The Agency did use
1997 air quality data where violations were documented during the early
portion of the 1997 ozone season. In order to revoke the 1-hour
standard based upon 1995-1997 air quality data, measurements
encompassing the complete ozone season would need to be available and
examined. Therefore, after today's action, the Agency intends to
publish, in early 1998, a subsequent notice which takes similar action
to revoke the 1-hour standard in additional areas that have air quality
data for 1995-1997 that do not violate the 1-hour standard. Detailed
air quality data information used for today's determinations is
contained in the Technical Support Document (TSD) to Docket No. A-97-
42.
IV. Tables
The ozone tables codified in today's action are significantly
different from the tables now included in 40 CFR part 81. The current
40 CFR part 81 designation listings (revised as of November 6, 1991)
include, by State and NAAQS pollutant, a brief description of areas
within the State and their respective designation. Today's action
includes completely new tables for ozone which indicate areas where the
1-hour standard no longer applies, as well as where the 1-hour standard
remains in effect.
V. Other Regulatory Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this
regulatory action from Executive Order 12866 review.
B. Regulatory Flexibility Act
Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA
must prepare a regulatory flexibility analysis assessing the impact of
any proposed or final rule on small entities (5 U.S.C. 603 and 604).
Alternatively, EPA may certify that the rule will not have a
significant impact on a substantial number of small entities. Small
entities include small businesses, small not-for-profit enterprises,
and government entities with jurisdiction over populations of less than
50,000. The EPA is certifying that this rule will not have a
significant impact on a substantial number of small entities.
C. Unfunded Mandates
Under Section 202 of the Unfunded Mandates Reform Act of 1995
(``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate; or to
private sector, of $100 million or more. Under Section 205, EPA must
select the most cost-effective and least burdensome alternative that
achieves the objectives of the rule and is consistent with statutory
requirements. Section 203 requires EPA to establish a plan for
informing and advising any small governments that may be significantly
or uniquely impacted by the rule.
The EPA has determined that the approval action promulgated does
not include a Federal mandate that may result in estimated costs of
$100 million or more to either State, local, or tribal governments in
the aggregate, or to the private sector. This Federal action imposes no
new requirements. Accordingly, no additional costs to State, local, or
tribal governments, or to the private sector, result from this action.
D. Submission to Congress and the General Accounting Office
Under 5 U.S.C. 801(a)(1)(A), as added by the Small Business
Regulatory Enforcement Fairness Act of 1996, EPA submitted a report
containing this rule and other required information to the U.S. Senate,
the U.S. House of Representatives and the Comptroller General of the
General Accounting Office prior to publication of the rule in today's
Federal Register. This rule is not a ``major rule'' as defined by 5
U.S.C. 804(2).
E. Petitions for Judicial Review
Under section 307(b)(1) of the CAA, petitions for judicial review
of this action must be filed in the United States Court of Appeals for
the appropriate circuit by May 18, 1998. Filing a petition for
reconsideration by the
[[Page 2728]]
Administrator of this final rule does not affect the finality of this
rule for the purposes of judicial review nor does it extend the time
within which a petition for judicial review may be filed, and shall not
postpone the effectiveness of such rule or action. This action may not
be challenged later in proceedings to enforce its requirements (see
section 307(b)(2)).
