Identification of Additional Ozone Areas Attaining the 1-Hour
Standard and to Which the 1-Hour Standard is no Longer Applicable
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: On May 18, 1998, the EPA published a proposal to approve the
identification of additional ozone areas attaining the 1-hour standard
and to which the 1-hour standard is no longer applicable. The comment
period concluded on June 17, 1998. Comments were received on the
proposal during the comment period. Today, the EPA is addressing the
comments and taking final action to approve the identification of six
additional ozone areas attaining the 1-hour standard and to which the
1-hour standard is no longer applicable. Upon promulgation of this
action, the Code of Federal Regulations (CFR) for ozone will be amended
to reflect such changes. Additionally, today's action is consistent
with the President's memorandum of July 16, 1997. The President's
memorandum called for EPA to publish 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 taken as indicated in the direct final rule published
on January 16, 1998, which, due to the receipt of adverse comments, was
withdrawn on March 16, 1998 and subsequently converted to a proposal.
On June 5, 1998, the Agency promulgated a final rule, effective
immediately, responding to the adverse comments, thus completing the
action identifying ozone areas where the 1-hour standard is no longer
applicable. According to the final rule, the Agency intended 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. The six additional
areas identified today are: Dayton-Springfield, Ohio; Detroit-Ann
Arbor, Michigan; Warrick County, Indiana; Grand Rapids, Michigan;
Poughkeepsie, New York; and Morgan County, Kentucky.
DATES: This action will be effective on July 22, 1998.

I. Background
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 Clean Air Act (Act) 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
promulgated regulations providing that revocation of the 1-hour ozone
national ambient air quality standard (NAAQS) would occur on an area-
by-area basis when EPA determined that an area was meeting the 1-hour
NAAQS. This was done in order to facilitate continuity in public health
protection during the transition to the new NAAQS.
Therefore, on January 16, 1998, in accordance with the President's
memorandum and the regulations promulgated on July 18, 1997, the Agency
issued a direct final rule (63 FR 2726) which identified 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. However, due to the
receipt of adverse comments, the direct final action was withdrawn on
March 16, 1998 (63 FR 12652) and converted to a proposed rule that had
previously been published on January 16, 1998 (63 FR 2804). The Agency
summarized and addressed all relevant public comments in a subsequent
final rule, published and effective on June 5, 1998 (63 FR 31014).
According to the final rule, the Agency intended 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 and to take similar action each year
thereafter.
On May 18, 1998, the EPA published a proposal to approve the
identification of six additional ozone areas attaining the 1-hour
standard and to which the 1-
[[Page 39433]]
hour standard is no longer applicable (63 FR 27247). Comments were
received on the proposal during the comment period ending on June 17,
1998.
II. Summary of Today's Action
The purpose of this document is to respond to comments received on
the May 18th proposed rule and finalize the identification of the six
additional areas that EPA has determined are not violating the 1-hour
standard and, therefore, with respect to which the 1-hour standard no
longer applies. The newly identified areas are: Dayton-Springfield,
Ohio; Detroit-Ann Arbor, Michigan; Warrick County, Indiana; Grand
Rapids, Michigan; Poughkeepsie, New York; and Morgan County, Kentucky.
III. Public Comments and EPA Responses
The following discussion summarizes and responds to the comments
received on the proposed rule published on May 18, 1998 (63 FR 27247).
Comment: The commenter states that clean monitoring data alone are
an insufficient legal basis for revocation of the applicability of the
1-hour standard in these areas and that all requirements of section
107(d)(3)(E) of the Act must be met in order to have the standard
revoked.
Response: The Agency previously addressed this question in its
promulgated rule of June 5, 1998 (63 FR 31014) and incorporates by
reference the discussion of this issue therein. In brief, as this
action is not a redesignation, but rather a determination that the 1-
hour NAAQS no longer applies to certain areas, pursuant to the
regulations promulgated in July 1997 as part of the rulemaking
regarding the ozone NAAQS (40 CFR 50.9(b)), the redesignation
requirements of section 107(d)(3)(E) do not apply to this action. These
regulations provide the legal basis for this action and specify the
criteria that must be met--the determination by EPA that an area has
air quality meeting the standard.
Comment: The commenter states that many of the areas contribute to
downwind air quality problems in Canada.
Response: Section 115 does not play a role in today's rulemaking
action because (1) EPA has not received any study or petition from an
international agency; (2) today's action does not impose or revoke any
air quality measures, as a result, the impact is neutral; and (3) the
criteria for determining the standard does not apply do not include an
analysis of international impacts. Furthermore, the EPA has not
received any comments from the government of Canada or private Canadian
citizens regarding this matter. In ongoing discussions between the EPA
and the Canadian government, the overall benefits of the nitrogen
oxides (NOX) State implementation plan (SIP) call (62 FR
60318, November 7, 1997) as a vehicle to deal with transport are widely
recognized.
Comment: Data considered for this rulemaking are incomplete. The
commenter notes a problem with malfunctioning ozone monitors in Allegan
County, Michigan and suspect monitoring conducted in Warrick County. In
addition, the commenter notes that the New Haven, Michigan ozone
monitor was not functioning during the May 1998 ozone episode.
Response: The EPA is only considering complete, quality assured air
quality data in this rulemaking. Today's action does not consider 1998
air quality data, because these data have not yet been quality assured
and have not been reported to the EPA. The 1995-1997 period was chosen
because it was the most recent 3-year period at the time of this rule
for which EPA and the States had complete data. With respect to the
question of malfunctioning monitors in Allegan County, this rulemaking
does not deal with Allegan County, therefore the comment is irrelevant
to this rulemaking action. With regard to comments on the quality of
Warrick County, Indiana ozone data, EPA considered only quality assured
ozone data for the 1995-1997 period and has no reason to suspect the
quality of the ozone data supplied by the State of Indiana.
Furthermore, the commenter provides no documentation to support the
claim of suspicious ozone data in Warrick County. As to the comment
that the monitor in New Haven, Michigan was not functioning during May
1998, draft air quality data reports for 1998 indicate that this
monitor was, in fact, running during the May 1998 period and has not
recorded any exceedances of the 1-hour ozone NAAQS.
Comment: The commenter notes that meteorological conditions in 1996
and 1997 were atypical and a meteorological analysis should be included
to show whether the areas have attained the 1-hour standard.
Response: The Agency previously addressed this concern regarding
variations in meteorological conditions in its final rule promulgated
on June 5, 1998 (63 FR 31014) and incorporates that discussion by
reference. Attainment of the ozone NAAQS is determined using three
consecutive years of data to account for variations in meteorological
conditions, as well as variations in volatile organic compounds (VOC)
and NOX emissions. The ozone NAAQS is designed to take into
account such variations.
Comment: Modeling predicts continued violations of the 1-hour NAAQS
in these areas.
Response: The EPA's authority for this action is based on the
regulatory provisions adopted when it promulgated the 8-hour ozone
NAAQS in July 1997 (62 FR 38856 (July 18, 1997)). Those regulations, in
40 CFR 50.9(b), provide that the ``1-hour standard set forth in this
section will no longer apply to an area once EPA determines that the
area has air quality meeting the 1-hour standard.'' Those regulations
specify a single criterion for determining that the 1-hour standard no
longer applies--the determination by EPA that an area has air quality
meeting the 1-hour standard. The EPA believes that is the only
criterion that may be applied in this rulemaking, and that it has been
satisfied in the case of all the areas covered by this action. In
essence, the commenters' issue, properly viewed, is not with the action
being taken at this time, but with the regulatory provision on which
this action is based. That regulation was promulgated in July 1997, the
commenters' issues are therefore untimely.
Comment: Areas are in noncompliance with their maintenance plans.
The commenter notes that Detroit, Michigan has experienced exceedances
of the ozone NAAQS, despite the implementation of required contingency
measures.
Response: Under section 107 of the Act, in order to be
redesignated, the Administrator must approve a maintenance plan that
meets the requirements of section 175(A) of the Act. Section 175(A)
requires maintenance plans to include contingency measures sufficient
to ``promptly correct any violation of the standard which occurs after
the redesignation of the area as an attainment area.'' On March 7,
1994, the EPA published the final approval of the redesignation request
and maintenance plan for the Detroit area. Subsequently, the area
violated the ozone standard and, in accordance with the approved
maintenance plan, the area implemented two contingency measures, a low
volatility gasoline program, and an expansion of the Stage I gasoline
vapor recovery program. Since that time, the area has experienced
exceedances, but not violations of the ozone standard. As the area is
attaining the standard, it satisfies the criterion for revocation of
the NAAQS specified in 40 CFR 50.9(b). In
[[Page 39434]]
fact, the exceedances experienced in the area in May 1998 occurred
prior to the control period for the low volatility gasoline program
which runs from June 1 to September 15. As a result, Michigan has
implemented its approved maintenance plan in the Detroit area and the
contingency measures appear to be working as designed to prevent future
violations of the 1-hour ozone NAAQS.
Comment: The EPA has determined that these areas interfere with
downwind areas' abilities to attain the 1-hour standard for ozone.
Response: The EPA is addressing this issue in the Eastern United
States through the NOX SIP call, which EPA has proposed (62
FR 60318, November 7, 1997). The proposal would place controls for
NOX emissions in large geographic upwind areas that contain
both attainment and nonattainment areas. The controls would reduce
NOX emissions and, as a result, ozone levels. The EPA has
also been petitioned, under section 126(b) of the Act, to place
controls on upwind stationary sources of NOX emissions. More
generally, it should be noted that upwind sources are subject to
section 110(a)(2)(D) regardless of whether the 1-hour standard
continues to apply to them. Accordingly, a determination that the 1-
hour standard does not apply to upwind areas does not preclude
additional reductions in the upwind areas. Furthermore, the only
criterion specified in 40 CFR 50.9(b) for revocation is EPA's
determination that the area itself is meeting the standard and the
factor referred to by the commenter is not relevant to that issue.
Comment: Children's health will be disproportionately and adversely
affected by this rule.
Response: EPA disagrees with this comment. Today's action will not
result in diminished controls or worsened air quality.
Comment: A group of commenters expressed concern that EPA did not
revoke the 1-hour NAAQS for the San Francisco Bay area despite its
continued violations, but did revoke the NAAQS for other areas
designated attainment. The commenters stated that EPA's approach
misapplies 40 CFR 50.9 (the regulation governing revocation of the 1-
hour standard), violates the Act and leads to inconsistent and
illogical results.
Response: The Agency previously addressed this comment in its final
rule promulgated on June 5, 1998 (63 FR 31014) and incorporates by
reference that discussion. The EPA is continuing the approach employed
in the earlier notices. The Presidential memorandum of July 16, 1997
(62 FR 38421, July 18, 1997) states, ``For areas where the air quality
does not currently attain the 1-hour standard, the 1-hour standard will
continue in effect.'' This policy should include maintenance and
attainment areas which currently violate the 1-hour standard. In
addition, on December 29, 1997, Richard D. Wilson, Acting Assistant
Administrator for Air and Radiation, issued guidance, entitled Guidance
for Implementing the 1-Hour Ozone and Pre-Existing PM10 NAAQS, which
reiterates that ``The EPA will not revoke the 1-hour standard in an
area that is violating that standard.'' The EPA believes that to
determine that the 1-hour standard ceases to apply to the Bay Area
would mislead the public into thinking their health was not at risk.
The EPA will not revoke the 1-hour NAAQS in an area that measures
violations during the prior 3-year period. The Bay Area had a total of
43 exceedances and 17 violations of the 1-hour standard since the June
1995 redesignation to attainment. Therefore, for all of the above
reasons, the Agency believes that it is prudent to keep the 1-hour
standard in place for the Bay Area.
In addition, EPA disagrees that its actions are inconsistent or
arbitrary. The commenters point out that an area with clean data for
all years in the 1990's, except for four or more exceedances in one
year, may not receive a determination that the standard will cease to
apply, but an area with exceedances in all years in the 1990's, except
for less than four exceedences in a 3-year period, may receive such a
determination. Factually, the commenters are correct because the 1-hour
NAAQS is based on air quality in a consecutive 3-year period. After EPA
revised the 1-hour NAAQS, instead of immediately revoking it for all
areas, EPA determined that it should be phased out by a determination
that it would cease to apply on any area that attained it for a 3-year
period, beginning 1994-96 and continuing for each 3-year period (on a
rolling basis) after that. Although an area may experience exceedances
after the 1-hour standard is determined no longer to apply, the new 8-
hour standard is designed to protect the air quality.
Comment: The commenter believes that retention of the 1-hour
standard in maintenance and attainment areas will not promote early
attainment of the 8-hour standard and EPA cannot justify its approach
based on a desire to protect air quality.
Response: The Agency previously addressed this comment in a final
rule promulgated on June 5, 1998 (63 FR 31014) and incorporates by
reference that discussion. Most, if not all, of the measures undertaken
for the purpose of attaining the 1-hour standard will assist in the
attainment of the 8-hour standard. This is because most areas with 1-
hour exceedances also have 8-hour exceedances. As more measures are
undertaken to meet the 1-hour standard, the 1-hour concentrations
composing the 8-hour average will decrease in magnitude, as will the
number of 8-hour exceedances.
IV. Analysis of Air Quality Data
This final action, to determine that the 1-hour standard no longer
applies to 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 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 document were based upon the most
recent data available, i.e., 1995-1997 data. Detailed air quality data
information used for today's determinations is contained in the
Technical Support Document (TSD) to Docket No. A-98-19.
V. 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 November 6, 1991 and most
recently revised June 5, 1998) include, by State and NAAQS pollutant, a
brief description of areas within the State and their respective
designation. Today's final action includes completely new entries for
the six additional ozone areas identified where the 1-hour standard no
longer applies.
VI. Other Regulatory Requirements
A. Executive Order 12866
Under Executive Order 12866 (58 FR 51735 (October 4, 1993)), the
Agency must determine whether the regulatory action is ``significant''
and therefore subject to Office of Management and Budget (OMB) review
and the requirements of the Executive Order. The OMB has exempted this
regulatory action from Executive Order 12866 review.
[[Page 39435]]
B. Rule Effective Date
The EPA finds that there is good cause for this action to become
effective immediately upon publication because a delayed effective date
is unnecessary due to the nature of this action, which is a
determination that the 1-hour ozone standard no longer applies. The
immediate effective date for this action is authorized under both 5
U.S.C. 553 (d)(1), which provides that rulemaking actions may become
effective less than 30 days after publication if the rule ``grants or
recognizes an exemption or relieves a restriction'' and section
553(d)(3), which allows an effective date less than 30 days after
publication ``as otherwise provided by the agency for good cause found
and published with the rule.''
C. Regulatory Flexibility Act
Under the Regulatory Flexibility Act, 5 U.S.C. 601 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),
unless EPA certifies 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 final rule will not have a significant impact on a
substantial number of small entities, because the determination that
the 1-hour standard ceases to apply does not subject any entities to
any additional requirements.
D. Unfunded Mandates
Under section 202 of the Unfunded Mandates Reform Act of 1995
(UMRA), 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 today's action, as promulgated, would
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.
E. 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).
F. Petitions for Judicial Review
Under section 307(b)(1) of the Act, petitions for judicial review
of this action must be filed in the United States court of Appeals for
the appropriate circuit by September 21, 1998. Filing a petition for
reconsideration by the 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)).
G. Applicability of Executive Order (E.O.)13045
On April 21, 1997, the President signed an Executive Order (13045)
entitled ``Protection of Children from Environmental Health Risks and
Safety Risks.'' This is the primary directive to Federal agencies and
departments that Federal health and safety standards now must include
an evaluation of the health or safety effects of the planned regulation
on children. For rules subject to the Executive Order, agencies are
further required to issue an explanation as to why the planned
regulation is preferable to other potentially effective and reasonable
feasible alternatives considered by the Agency.
This final rule is not subject to E.O. 13045, entitled ``Protection
of Children from Environmental Health Risks and Safety Risks'' (62 FR
19885, April 23, 1997), because this is not an economically significant
regulatory action as defined by E.O. 12866, and it does not involve
decisions on environmental health risks or safety risks that may
disproportionately affect children.
