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.
     E-mail: [email protected].
     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.

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).

[email protected].

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.
Laura Yoshii,
Acting Regional Administrator, Region IX.
