40 CFR Part 81

[WI44-01-6426a; FRL-5053-5]

Designation of Areas for Air Quality Planning Purposes;

Wisconsin; Redesignation of Oshkosh, WI, to Attainment for Carbon

Monoxide

AGENCY: United States Environmental Protection Agency (USEPA).

ACTION: Final rule.

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

SUMMARY: The USEPA redesignates Oshkosh, Wisconsin from unclassifiable

to attainment status for carbon monoxide. The State of Wisconsin

requested this redesignation and provided the necessary monitoring data

for USEPA to approve the change. The redesignation has no substantive

effect because unclassifiable areas are subject to the same

requirements as attainment areas. Elsewhere in this Federal Register,

USEPA is proposing approval of and soliciting public comment on this

redesignation. If adverse comments are received in the time period

specified below, USEPA will withdraw this final rule and address the

comments in a subsequent final rule.

DATES: This final rule will be effective October 17, 1994 unless notice

is received within 30 days of this publication that someone wishes to

submit adverse comments. If the effective date is delayed, timely

notice will be published in the Federal Register.

ADDRESSES: Written comments should be sent to: Carlton T. Nash, Chief,

Regulation Development Section, Air Toxics and Radiation Branch (AT-

18J), U.S. Environmental Protection Agency, 77 West Jackson Boulevard,

Chicago, Illinois 60604.

Copies of the redesignation request and USEPA's analysis are

available for inspection at the U.S. Environmental Protection Agency,

Region 5, Air and Radiation Division, 77 West Jackson Boulevard,

Chicago, Illinois 60604. (It is recommended that you telephone Megan

Beardsley at (312) 886-0669 before visiting the Region 5 Office.)

A copy of this SIP revision is also available at the Office of Air

and Radiation, Docket and Information Center (Air Docket 6102), room

M1500, U.S. Environmental Protection Agency, 401 M Street, SW.,

SUPPLEMENTARY INFORMATION:

I. Background

In November 1991, USEPA designated Oshkosh, Wisconsin as an

unclassifiable area for carbon monoxide (56 FR 56850) because the

available air quality data was not representative of air quality at the

date of enactment of the 1990 Clean Air Act Amendments. Exceedances of

the National Ambient Air Quality Standards (NAAQS) for carbon monoxide

had been recorded in Oshkosh, Wisconsin in late 1988 and early 1989,

but the emissions causing the exceedances were brought under control

later in 1989. These controls were approved by USEPA and incorporated

into the State Implementation Plan on October 8, 1992 (57 FR 46309).

Wisconsin's current request, submitted on April 7, 1994, is to

change the designation of Oshkosh from unclassifiable to attainment

based on recent ambient air quality measurements.

II. Evaluation of State Submission

A. Procedural Background

Redesignation requests are processed under section 107(d)(3) of the

Clean Air Act (the Act). While section 107(d)(3)(E) specifies a number

of requirements for areas requesting redesignation from nonattainment

to attainment, the redesignation of unclassifiable areas is not

explicitly addressed. However, the general criteria governing

designations, set forth in section 107(d)(1)(A), do apply. Therefore,

to qualify an unclassified area for redesignation to attainment, the

State must show that the area has attained the relevant standard.

For a carbon monoxide area to be designated as attainment for a

pollutant, it must meet the NAAQS for that pollutant (40 CFR part 50),

based on the most recent two years of data. In its redesignation

request, Wisconsin submitted carbon monoxide data for Oshkosh from

January 24, 1992 to January 31, 1994 (when the monitor was shut down).

Wisconsin collected the air quality data as required in the 1992 SIP

revision and under procedures in accordance with the USEPA's monitoring

requirements set forth in 40 CFR part 58. This data has been entered

into USEPA's Aerometric Information Retrieval System (AIRS) and is

summarized in USEPA's Technical Support Document for this action (M.

Beardsley to Files, July 20, 1994). The data show that Oshkosh is well

under the NAAQS for carbon monoxide concentrations and, thus, meets the

requirements for attainment status.

C. Action

The USEPA redesignates the City of Oshkosh, Wisconsin from

unclassifiable to attainment for carbon monoxide.

Because USEPA considers this action noncontroversial, we are

approving it without prior proposal. This action will become effective

on October 17, 1994. However, if we receive adverse or critical

comments by September 16, 1994, USEPA will publish a document that

withdraws today's action and will address all public comments in a

subsequent final rule based on the proposal published in the proposed

rule section. The public comment period will not be extended or

reopened.

IV. Miscellaneous

A. Executive Order 12866

The Office of Management and Budget has exempted this regulatory

action from Exectutive Order 12866 review.

B. Regulatory Flexibility

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 entities with jurisdiction over populations of less than

50,000.

This redesignation does not create any new requirements. Therefore,

I certify that this action does not have a significant impact on any

small entities affected.

D. 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 October 17, 1994. 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)).
