03-4255. Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Revisions to the Air Resource Regulations

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the State of Pennsylvania for the purpose of modifying definitions related to “major modification,” “modification,” “potential to emit,” “responsible official” and “secondary emissions.” 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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 March 27, 2003.

ADDRESSES:

Written comments should be addressed to Makeba A. Morris, Chief, Permits and Technical Assessment Branch], Air protection Division, Mail Code 3AP11, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103.
