AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve a revision to the Maricopa County Environmental Services Department (MCESD) portion of the Arizona State Implementation Plan (SIP). Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), we are proposing to approve a local rule that regulates excess emissions from malfunctions, startups, and shutdowns.

DATE:

Any comments on this proposal must arrive by September 26, 2002.

ADDRESSES:

Mail comments to Gerardo Rios, Permits Office Chief (AIR-3), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105.

You can inspect a copy of the submitted SIP revision and EPA's technical support document (TSD) at our Region IX office during normal business hours. You may also see a copy of the submitted SIP revision at the following locations:

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of local MCESD Rule 140. In the Rules section of this Federal Register, we are approving this local rule in a direct final action without prior proposal because we believe this SIP revision is not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule. We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action.

Dated: July 25, 2002.

Keith Takata,

Acting Regional Administrator, Region IX.
