04-6213. Revisions to the California State Implementation Plan, South Coast Air Quality Management District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern volatile organic compound (VOC) and ammonia emissions from composting and related activities. We are proposing to approve local rules to regulate these 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, 2004.

ADDRESSES:

Send comments to Andy Steckel, Rulemaking Office Chief (AIR-4), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901 or e-mail to [e-mail], or submit comments at http://www.regulations.gov.

You can inspect copies of the submitted SIP revisions, EPA's technical support documents (TSDs), and public comments at our Region IX office during normal business hours by appointment. You may also see copies of the submitted SIP revisions by appointment at the locations listed below.

FOR FURTHER INFORMATION CONTACT:

Jerald S. Wamsley, EPA Region IX, at either [phone], or [e-mail].

SUPPLEMENTARY INFORMATION:

This proposal addresses the following local SCAQMD rules: Rule 1133, Composting and Related Operations—General Administrative Requirements, Rule 1133.1, Chipping and Grinding Activities, Rule 1133.2, Emission Reductions From Co-Composting Operations. In the Rules and Regulations 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. 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: February 4, 2004.

Keith Takata,

Acting Regional Administrator, Region IX.
