40 CFR Part 52

[EPA-R09-OAR-2010-0503; FRL-9183-5]


Revisions to the California State Implementation Plan, South 
Coast Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to the South Coast Air 
Quality Management District (SCAQMD) portion of the California State 
Implementation Plan (SIP). These revisions concern oxides of nitrogen 
(NOx) emissions from natural gas-fired, fan-type central furnaces and 
other miscellaneous NOx sources. We are proposing to approve the local 
rules 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 September 3, 2010.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2010-0503, by one of the following methods:
    1. Federal eRulemaking Portal: http://www.regulations.gov. Follow 
the on-line instructions.
    2. E-mail: [email protected].
    3. Mail or deliver: Andrew Steckel (Air-4), U.S. Environmental 
Protection Agency Region IX, 75 Hawthorne Street, San Francisco, CA 
94105-3901.
    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

[[Page 46881]]

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. Electronic files should avoid the use of 
special characters, any form of encryption, and be free of any defects 
or viruses.
    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 
appointment during normal business hours with the contact listed in the 
FOR FURTHER INFORMATION CONTACT section.

FOR FURTHER INFORMATION CONTACT: Idalia Perez, EPA Region IX, (415) 
972-3248, [email protected].

SUPPLEMENTARY INFORMATION: This proposal addresses the following local 
rules: Rule 1111, Reduction of NOx Emissions from Natural Gas-Fired, 
Fan-Type Central Furnaces, and Rule 1147, NOx Reductions from 
Miscellaneous Sources. 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 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 these rules and if that provision may be severed from the 
remainder of the rules, we may adopt as final those provisions of the 
rules 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: July 7, 2010.
Keith Takata,
Acting Regional Administrator, Region IX.
