03-9042. Revisions to the California State Implementation Plan, Lake County Air Quality Control District and San Diego County Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Lake County Air Quality Management District (LCAQMD) and San Diego County Air Pollution Control District (SDCAPCD) portions of the California State Implementation Plan (SIP). The LCAQMD and SDCAPCD revisions concern the emission of particulate matter (PM-10) from open burning. We are proposing to approve the local rules that regulate this emission source under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES:

Any comments on this proposal must arrive by May 16, 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.

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of local LCAQMD sections 226.5, 232.1, 238.5, 249.3, 250.5, 431.5, 431.7, 432.5, 433, 433.5, 436, and 436.5 and SDAPCD rule 101. This proposal also addresses the recision of SIP LCAQMD section 442 and SDCAPCD rules 101 through 112. In the rules section of this Federal Register, we are approving these local rules 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 commend 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: March 5, 2003.

Alexis Strauss,

Acting Regional Administrator, Region IX.
