Approval and Promulgation of Air Quality Implementation Plans;
The Commonwealth of Kentucky--Proposed Disapproval of the Request To
Redesignate the Kentucky Portion of the Cincinnati-Northern Kentucky
Moderate Ozone Nonattainment Area to Attainment and the Associated
Maintenance Plan
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to disapprove the Commonwealth of Kentucky
Natural Resources and Environmental Protection Cabinet's (Cabinet)
request to redesignate the Kentucky portion of the Cincinnati-Northern
Kentucky moderate ozone nonattainment area to attainment and the
associated maintenance plan as a revision to the state implementation
plan (SIP). The EPA determined that the area registered a violation of
the ozone national ambient air quality standard (NAAQS). As a result,
the Northern Kentucky area no longer meets the statutory criteria for
redesignation to attainment of the ozone NAAQS.
DATES: Comments on this proposed action must be received in writing by
May 17, 1996.
ADDRESSES: Written comments on this action should be addressed to Kay
Prince at the Environmental Protection Agency, Region 4, Air Programs
Branch, 345 Courtland Street, NE, Atlanta, Georgia 30365.

public inspection during normal business hours at the following

SUPPLEMENTARY INFORMATION: On November 11, 1994, the Cabinet submitted
a request to EPA to redesignate the Kentucky portion of the Cincinnati-
Northern Kentucky moderate interstate ozone nonattainment area from
nonattainment to attainment. On that date, the Cabinet also submitted a
maintenance plan for the area as a revision to the Kentucky SIP.
According to section 107(d)(3)(E) of the Clean Air Act (CAA), 42
U.S.C. 7407(d)(3)(E), redesignation requests must meet five specific
criteria in order for EPA to redesignate an area from nonattainment to
attainment:
1. The Administrator determines that the area has attained the
ozone NAAQS;
2. The Administrator has fully approved the applicable
implementation plan for the area under section 110(k);
3. The Administrator determines that the improvement in air quality
is due to permanent and enforceable reductions in emissions resulting
from implementation of the applicable implementation plan and
applicable Federal air pollution control regulations and other
permanent and enforceable reductions;
4. The Administrator has fully approved a maintenance plan for the
area as meeting the requirements of section 175A; and
5. The State containing such area has met all requirements
applicable to the area under section 110 and part D.
The Northern Kentucky area appeared to have attained the NAAQS,
based on air quality data monitored from 1992 through 1994. The
Cabinet's November 11, 1994, request for redesignation and its
submittal of a maintenance plan SIP revision for the Northern Kentucky
area were evaluated by EPA and determined to have satisfied the five
criteria listed above. However, after review of the 1995 ambient air
quality data, EPA determined that the area registered a violation of
the ozone NAAQS. The ambient data has been quality assured according to
established procedures for validating such monitoring data. The Cabinet
does not contest that the area violated the NAAQS for ozone during the
1995 ozone season. As a result, the Northern Kentucky area no longer
meets the statutory criteria for redesignation to attainment of the
ozone NAAQS found in section 107(d)(3)(E)(i) of the CAA.
The maintenance plan SIP revision is not approvable because its
demonstration is based on a level of ozone precursor emissions in the
ambient air thought to represent an inventory of emissions that would
provide for attainment and maintenance. That underlying basis of the
maintenance plan's demonstration is no longer valid due to the
violation of the NAAQS that occurred during the 1995 ozone season.
Proposed Action
EPA is proposing to disapprove the Commonwealth's November 11, 1994
redesignation request and maintenance plan SIP revision.
EPA is soliciting public comments on this notice and on issues
relevant to EPA's proposed action. Comments will be considered before
taking final action. Interested parties may participate in the Federal
rulemaking procedure by submitting written comments to the person
listed in the ADDRESSES section.
The agency has reviewed this request for revision of the Federally-
approved SIP for conformance with the provisions of the CAA. The Agency
has determined that this action does not conform with the statute as
amended and should be disapproved.
This action has been classified as a Table 3 action for signature
by the Regional Administrator under the procedures published in the
Federal Register on January 19, 1989 (54 FR 2214-2225), as revised by a
July 10, 1995, memorandum from Mary Nichols, Assistant Administrator
for Air and Radiation. The Office of Management and Budget (OMB) has
exempted this regulatory action from E.O. 12866 review.
Nothing in this action shall be construed as permitting or allowing
or establishing a precedent for any future request for a revision to
any state implementation plan. Each request for revision to the state
implementation plan shall be considered separately in light of specific
technical, economic, and environmental factors and in relation to
relevant statutory and regulatory requirements.
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.
EPA's denial of the State's redesignation request under section
107(d)(3)(E) does not affect any existing requirements applicable to
small
[[Page 16739]]
entities nor does it impose new requirements. The area retains its
current designation status and will continue to be subject to the same
statutory requirements. To the extent that the area must adopt
regulations, based on its nonattainment status, EPA will review the
effect of those actions on small entities at the time the state submits
those regulations. Therefore, I certify that denial of the
redesignation request will not affect a substantial number of small
entities.
