Clean Air Act Promulgation of Extension of Attainment Date for 
Ozone Nonattainment Area; Kentucky; Indiana

AGENCY: Environmental Protection Agency (USEPA).

ACTION: Direct final rule.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (USEPA) is extending 
the attainment date for the Louisville interstate moderate ozone 
nonattainment area from November 15, 1996, to November 15, 1997. This 
extension is based in part on monitored air quality readings for the 
national ambient air quality standard (NAAQS) for ozone during 1996. 
Accordingly, USEPA is revising the table in the Code of Federal 
Regulations concerning ozone attainment dates in this area. In this 
action, USEPA is approving the States' request through a ``direct 
final'' rulemaking; the rationale for this

[[Page 55174]]

approval is set forth. Elsewhere in this Federal Register, USEPA is 
proposing approval and soliciting written comment on this action; if 
adverse written comments are received, USEPA will withdraw the direct 
final rule and address the comments received in a new final rule; 
otherwise no further rulemaking will occur on this attainment date 
extension request.

DATES: This action is effective December 22, 1997 unless substantive 
written adverse comments not previously addressed by the State or USEPA 
are received by November 24, 1997. If the effective date is delayed, 
timely notice will be published in the Federal Register.

ADDRESSES: Written comments may be mailed to Joey LeVasseur at the 
USEPA Region 4 address listed below or to J. Elmer Bortzer, Chief, 
Regulation Development Section, Air Programs Branch (AR-18J), Region 5

SUPPLEMENTARY INFORMATION:

Request for Attainment Date Extension for the Louisville Moderate Ozone 
Nonattainment Area

    On January 8, 1996, KNREPC requested a one-year attainment date 
extension for the Kentucky portion of the Louisville moderate ozone 
nonattainment area which consists of Jefferson, Bullitt, and Oldham 
Counties in Kentucky. Similarly, on November 15, 1996, Indiana 
requested a one-year attainment date extension for the Indiana portion 
of the Louisville moderate ozone nonattainment area which consists of 
Clark and Floyd Counties. Since this area is classified as a moderate 
ozone nonattainment area, the statutory ozone attainment date 
prescribed by section 181(a) of the Clean Air Act (CAA) is November 15, 
1996. The State submittals request that the attainment date be extended 
to November 15, 1997.

CAA Requirements and USEPA Actions Concerning Designation and 
Classification

    Section 107(d)(4) of the CAA requires the States and USEPA to 
designate areas as attainment, nonattainment, or unclassifiable for 
ozone as well as other pollutants for which national ambient air 
quality standards (NAAQS) have been set. Section 181(a)(1) requires 
that ozone nonattainment areas be classified as marginal, moderate, 
serious, severe, or extreme, depending on their air quality. In a 
series of Federal Register documents, USEPA completed this process by 
designating and classifying all areas of the country for ozone. See, 
e.g., 56 FR 58694 (Nov. 6, 1991); 57 FR 56762 (Nov. 30, 1992).
    Areas designated nonattainment for ozone are required to meet 
attainment dates specified under the CAA. The Louisville ozone 
nonattainment area was designated nonattainment and classified moderate 
for ozone pursuant to 56 FR 58694 (November 6, 1991). By this 
classification, its attainment date became November 15, 1996. A 
discussion of the attainment dates is found in 57 FR 13498 (April 16, 
1992) (the General Preamble).

CAA Requirements Concerning Meeting the Attainment Date

    Section 181(b)(2)(A) requires the Administrator, within six months 
of the attainment date, to determine whether ozone nonattainment areas 
had attained the NAAQS. For ozone, USEPA determines attainment status 
on the basis of the expected number of exceedances of the NAAQS over 
the most recent three-year period. See General Preamble, 57 FR 13506. 
In the case of moderate ozone nonattainment areas, the three-year 
period is 1994-1996.
    A review of the actual ambient air quality ozone data from the 
USEPA Aerometric Information Retrieval System (AIRS) shows that five 
air quality monitors located in the Louisville ozone nonattainment area 
recorded exceedances of the NAAQS for ozone during the three year 
period from 1994 to 1996. The exceedances at the Clark County, Indiana, 
monitor averaged more than 1.0 over the three year period, which 
constitutes a violation of the ozone NAAQS for the Louisville area 
during this three-year period. Thus, the area did not meet the November 
15, 1996 attainment date. (See Table 1.)

\1\ The New Albany ozone monitor began operation in 1977, but stopped collecting ozone data in 1980. Ozone      
  monitoring at this site resumed on April 1, 1995.                                                             

    CAA section 181(b)(2)(A) further states that, for areas classified 
as marginal, moderate, or serious, if the Administrator determines that 
the area did not attain the standard by its attainment date, the area 
must be reclassified to the next higher classification. However, CAA 
section 181(a)(5) provides an exemption from this reclassification 
requirement. Under this exemption, USEPA may grant up to two, one-year 
extensions of the attainment date under specified conditions:
    Section 181(a)(5) states that upon application by any State, the 
Administrator may extend [the attainment date] for one additional year 
(referred to as the ``Extension Year'') if:
    (A) The State has complied with all requirements and commitments 
pertaining to the area in the applicable implementation plan, and
    (B) No more than one exceedance of the national ambient air quality 
standard level for ozone has occurred in the area in the year preceding 
the Extension Year.
    The USEPA interprets this provision to authorize the granting of a 
one-year extension upon request by a State, under the following minimum 
conditions.
    (1) The State has complied with or is taking significant steps to 
comply with all requirements and commitments in the USEPA approved 
ozone State Implementation Plan (SIP) for the area, and
    (2) The area has no more than one measured exceedance of the ozone 
NAAQS at each monitor in the area during the year that includes the 
attainment date (or the subsequent year, if a second one-year extension 
is being requested).

Compliance With State Implementation Plans

    Indiana and Kentucky have complied with the CAA SIP revision 
requirements for moderate ozone nonattainment areas. Both States 
certified they are implementing their ozone SIPs for the Louisville 
area. Therefore, the implementation plan criterion for the attainment 
date extension is satisfied. All of the states' SIP submittals may be 
examined during regular business hours at the EPA Regional offices 
listed above in the addresses section of this notice.

Compliance With Air Quality Monitoring Criteria

    In the extension requests, Kentucky and Indiana indicated that no 
monitor in the Louisville area had more than one exceedance each during 
1996. The 1996 monitoring data has been quality controlled and quality 
assured, as has the data for 1994 and 1995. These data are summarized 
in Table 1. Three of the seven ozone monitors in the Louisville area 
recorded one exceedance each during 1996, but none recorded more than 
one exceedance in 1996. This satisfies the air quality data criterion 
for the attainment date extension.
    USEPA has reviewed the States' formal extension requests, and has 
determined that the requirements for a one-year extension of the 
attainment date have been fulfilled. USEPA is therefore approving the 
Kentucky and Indiana attainment date extension requests for the 
Louisville ozone nonattainment area. As a result, the Kentucky Control 
Strategy for Ozone which is codified at 40 CFR 52.930 and the Indiana 
Control Strategy for Photochemical Oxidants (hydrocarbons) which is 
codified at 40 CFR 52.777 are being amended to record these attainment 
date extensions. The chart in 40 CFR 81.318 entitled ``Kentucky-Ozone'' 
is being modified to reflect USEPA's approval of Kentucky's attainment 
date extension request. The chart in 40 CFR 81.315 entitled ``Indiana-
Ozone'' is also being modified to reflect USEPA's approval of Indiana's 
attainment date extension request.

Final Action

    USEPA is approving the attainment date extension requests submitted 
by Kentucky and Indiana to extend the Louisville moderate ozone 
nonattainment area attainment date from November 15, 1996 to November 
15, 1997 without prior proposal because the Agency views this as a 
noncontroversial amendment and anticipates no adverse comments. 
However, in a separate document in this Federal Register publication, 
USEPA is proposing to approve this part 52 and part 81 action should 
written adverse or critical comments be filed. This action will be 
effective December 22, 1997 unless, by November 24, 1997 written 
adverse or critical comments are received.
    If the USEPA receives such comments, this action will be withdrawn 
before the effective date by publishing a subsequent document that will 
withdraw the final action. All written public comments received will 
then be addressed in a subsequent final rule based on this action 
serving as a proposed rule. USEPA will not institute a second comment 
period on this action. Any parties interested in commenting on this 
action should do so at this time. If no such comments are received, the 
public is advised that this action will be effective on December 22, 
1997.
    Nothing in this action should be construed as permitting or 
allowing or establishing a precedent for any future request for 
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.

Administrative Requirements

A. Executive Order 12866

    The Office of Management and Budget (OMB) has exempted this 
regulatory action from E.O. 12866 review.

B. Regulatory Flexibility Act

    Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., USEPA 
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, USEPA 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

[[Page 55176]]

entities with jurisdiction over populations of less than 50,000.
    Extension of an area's attainment date under the CAA does not 
impose any new requirements on small entities. Extension of an 
attainment date is an action that affects a geographic area and does 
not impose any regulatory requirements on sources. USEPA certifies that 
the approval of the attainment date extension will not affect 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, USEPA 
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, USEPA 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 USEPA to establish a plan for 
informing and advising any small governments that may be significantly 
or uniquely impacted by the rule.
    USEPA 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 approves pre-
existing requirements under State or local law, and 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, USEPA 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 Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 22, 1997. 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).)
