03-4512. Revisions to the California State Implementation Plan, Mojave Desert Air Quality Management District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Mojave Desert Air Quality Management District (MDAQMD) portion of the California State Implementation Plan (SIP). These revisions concern Oxides of Nitrogen (NO_X) emissions from Portland cement kilns. We are proposing to approve a local rule 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 March 31, 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 document (TSD) 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.

Mojave Desert Air Quality Management District, 14306 Park Avenue, Victorville, California 92392.

A copy of the rule may also be available via the Internet at http://www.arb.ca.gov/​drdb/​drdbltxt.htm. Please be advised that this is not an EPA website and may not contain the same version of the rule that was submitted to EPA.

SUPPLEMENTARY INFORMATION:

This proposal addresses the MDAQMD rule 1161. In the Rules and Regulations section of this Federal Register, we are approving this local rule 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 31, 2003.

Alexis Strauss,

Acting Regional Administrator, Region IX.
