02-28496. Approval and Promulgation of Air Quality Implementation Plans; Designation of Areas for Air Quality Planning Purposes; Pennsylvania; Redesignation of the Allegheny County Carbon Monoxide Nonattainment Area and Approval of Miscellaneous ...

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania for the purpose of redesignating the Pittsburgh area carbon monoxide (CO) nonattainment area to attainment, establish a maintenance plan for the area, and approve the 1990 base year inventory for CO for the area. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this action, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.

DATES:

Comments must be received in writing by December 12, 2002.

ADDRESSES:

Written comments should be mailed to David L. Arnold, Chief, Air Quality Planning and Information Services Branch, Mailcode 3AP21, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103. Copies of the documents relevant to this action are available for public inspection during normal business hours at the Air Protection Division, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103; the Air and Radiation Docket and Information Center, 1301 Constitution Avenue, NW., Room B108, Washington, DC 20460; and Pennsylvania Department of Environmental Protection, Bureau of Air Quality, PO Box 8468, 400 Market Street, Harrisburg, Pennsylvania 17105.

SUPPLEMENTARY INFORMATION:

For further information, please see the information provided in the direct final action, with the same title, that is located in the “Rules and Regulations” section of this Federal Register publication.

Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this redesignation request, maintenance plan and emissions inventory for the CO nonattainment area in southwestern Pennsylvania, and if that provision may be severed from the remainder of the rule, EPA may adopt as final those provisions of the rule that are not the subject of an adverse comment.
