Revisions to the Arizona State Implementation Plan, Maricopa

County Air Quality Department and Maricopa County

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve revisions to the Maricopa County

Air Quality Department (MCAQD) and Maricopa County portions of the

Arizona State Implementation Plan (SIP). These revisions concern PM-10 emissions from open outdoor fires and indoor fireplaces at commercial and institutional establishments, primary and secondary MCAQD ambient air quality standards, and residential woodburning devices. We are proposing approval of local rules that 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 December 9, 2009.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR- 2009-0042, by one of the following methods:

Federal eRulemaking Portal: www.regulations.gov. Follow the on-line instructions.

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: Al Petersen, Rulemaking Office (AIR- 4), U.S. Environmental Protection Agency, Region IX, (415) 947-4118, petersen.alfred@epa.gov.

SUPPLEMENTARY INFORMATION: This proposal addresses the approval of local MCAQD Rules 314 and 510 and MC Ordinance P-26. 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: April 13, 2009.

Acting Regional Administrator, Region IX.
