03-6709. Revisions to the California State Implementation Plan, Imperial County Air Pollution Control District, Mendocino County Air Quality Management District, and Monterey Unified Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Imperial County Air Pollution Control District (ICAPCD), Mendocino County Air Quality Management District (MCAQMD), and Monterey Bay Unified Air Pollution Control District (MBUAPCD) portion of the California State Implementation Plan (SIP). These revisions concern administrative changes for clarity and consistency. We are proposing to approve local rules and a rule rescission to regulate emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES:

Any comments on this proposal must arrive by April 21, 2003.

ADDRESSES:

Mail comments to Andy Steckel, Rulemaking Office Chief (AIR-4), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.

You can inspect copies of the submitted SIP revisions and EPA's technical support documents (TSDs) at our Region IX office during normal business hours. You may also see copies of the submitted SIP revisions at the following locations: California Air Resources Board, Stationary Source Division, Rule Evaluation Section, 1001 “I” Street, Sacramento, CA 95814.

SUPPLEMENTARY INFORMATION:

This proposal addresses the following local rules: ICAPCD 115, MCAQMD 400(b), and recission of MBUAPCD 209. In the Rules and Regulations section of this Federal Register, we are approving these local rules and rule recission in a direct final action without prior proposal because we believe these SIP revisions are 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. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

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: January 17, 2003.

Alexis Strauss,

Acting Regional Administrator, Region IX.
