Revisions to the California State Implementation Plan, Great Basin Unified Air Pollution Control District and Ventura County Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Great Basin Unified Air Pollution Control District (GBUAPCD) and Ventura County Air Pollution Control District (VCAPCD) portions of the California State Implementation Plan (SIP). The GBUAPCD revisions concern the emission of particulate matter (PM-10) from open fires and incinerator burning. The VCAPCD revisions concern the emission of particulate matter (PM-10) from open burning. We are proposing to approve local rules that administer regulations and 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 July 7, 2004.

ADDRESSES:

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

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of local GBUAPCD Rules 406 and 407 and VCAPCD Rule 56. 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 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. 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: May 12, 2004.

Laura Yoshii,

Deputy Regional Administrator, Region IX.
