Revisions to the Arizona State Implementation Plan, Maricopa 
County Environmental Services Department

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA is proposing to approve a revision to the Maricopa County 
Environmental Services Department (MCESD) portion of the Arizona State 
Implementation Plan (SIP). This revision concerns particulate matter 
(PM-10) emissions from open burning. We are proposing approval of a 
local rule that regulates 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 June 7, 2007.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2006-0827, by one of the following methods:
     Federal eRulemaking Portal: http://www.regulations.gov. 
Follow the on-line instructions.

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 http://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 http://www.regulations.gov or e-mail. http://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 http://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

[email protected].

SUPPLEMENTARY INFORMATION: This proposal addresses the approval of 
local MCESD Rule 314. 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 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. 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: March 23, 2007.
Laura Yoshii,
Acting Regional Administrator, Region IX.
