04-14824. Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Revision to the 1-Hour Ozone Maintenance Plan for the Pittsburgh-Beaver Valley Area To Reflect the Use of MOBILE6

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 amending Pennsylvania's ten-year plan to maintain the 1-hour ozone national ambient air quality standard (NAAQS) in the Pittsburgh-Beaver Valley maintenance area. The maintenance plan is being amended to revise the volatile organic compound (VOC) and nitrogen oxides (NO_X) motor vehicle emission budgets (MVEBs) to reflect the use of MOBILE6. 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 August 2, 2004.

Instructions: Direct your comments to Docket ID No. PA217-4230. EPA's policy is that all comments received will be included in the public docket without change, including any personal information provided, unless the comment includes information claimed to be Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Do not submit information that you consider to be CBI or otherwise protected through regulations.gov or e-mail.

If you submit an electronic comment, EPA recommends that you include your name and other contact information in the body of your comment and with any disk or CD-ROM you submit. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment. Electronic files should avoid the use of special characters, any form of encryption, and be free of any defects or viruses.
