E7-21320. Revisions to the California State Implementation Plan, Great Basin Unified Air Pollution Control District and Mojave Desert Air Quality Management 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 Mojave Desert Air Quality Management District (MDAQMD) portions of the California State Implementation Plan (SIP). Under authority of the Clean Air Act as amended in 1990 (CAA or the Act), we are proposing to approve local rules that concern particulate matter (PM-10) emissions from wood burning appliances and open outdoor burning.

DATES:

Any comments on this proposal must arrive by November 30, 2007.

ADDRESSES:

Submit comments, identified by docket number EPA-R09-OAR-2007-0459, by one of the following methods:

• Federal eRulemaking Portal: www.regulations.gov. Follow the on-line instructions.
• E-mail: [e-mail].
• Mail or deliver: Andrew Steckel (Air-4), U.S. Environmental Protection Agency Region IX, 75 Hawthorne Street, San Francisco, CA 94105.

Instructions: All comments will be included in the public docket without change and may be made available online at www.regulations.gov, including any personal information provided, unless the comment includes Confidential Business Information (CBI) or other information whose disclosure is restricted by statute. Information that you consider CBI or otherwise protected should be clearly identified as such and should not be submitted through www.regulations.gov or e-mail. www.regulations.gov is an “anonymous access” system, and EPA will not know your identity or contact information unless you provide it in the body of your comment. If you send e-mail directly to EPA, your e-mail address will be automatically captured and included as part of the public comment. If EPA cannot read your comment due to technical difficulties and cannot contact you for clarification, EPA may not be able to consider your comment.

Docket: The index to the docket for this action is available electronically at www.regulations.gov and in hard copy at EPA Region IX, 75 Hawthorne Street, San Francisco, California. While all documents in the docket are listed in the index, some information may be publicly available only at the hard copy location (e.g., copyrighted material), and some may not be publicly available in either location (e.g., CBI). To inspect the hard copy materials, please schedule an appointment during normal business hours with the contact listed in the FOR FURTHER INFORMATION CONTACT section.

FOR FURTHER INFORMATION CONTACT:

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of GBUAPCD Rules 405 and 431 and MDAQMD Rule 444. 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 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.

Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, EPA 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: August 22, 2007.

Laura Yoshii,

Acting Regional Administrator, Region IX.
