ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R09-OAR-2012-0808; FRL-9750-3]

Revisions to the California State Implementation Plan, Monterey 
Bay Unified Air Pollution Control District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to the Monterey Bay 
Unified Air Pollution Control District (MBUAPCD) portion of the 
California State Implementation Plan (SIP). This revision concerns 
opacity standards related to multiple pollutants, including particulate 
matter (PM) emissions from several different types of sources, ranging 
from fugitive dust to gas turbines. We are proposing to approve a local 
rule to regulate these emission sources under the Clean Air Act (CAA or 
the Act).

DATES: Any comments on this proposal must arrive by January 9, 2013.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2012-0808, by one of the following methods:
    1. Federal eRulemaking Portal: www.regulations.gov. Follow the on-
line instructions.
    2. Email: steckel.andrew@epa.gov.
    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 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 email. 
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 email directly to EPA, your email 
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: Generally, documents in the docket for this action are 
available electronically at www.regulations.gov and in hard copy at EPA 
Region IX, 75 Hawthorne Street, San Francisco, California 94105-3901. 
While all documents in the docket are listed at www.regulations.gov, 
some information may be publicly available only at the hard copy 
location (e.g., copyrighted material, large maps), 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

FOR FURTHER INFORMATION CONTACT: Idalia P[eacute]rez, EPA Region IX, 
(415) 972-3248, perez.idalia@epa.gov.

SUPPLEMENTARY INFORMATION: This proposal addresses the following local 
rule: Rule 400, Visible Emissions. 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 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.
    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: October 26, 2012.
Jared Blumenfeld,
Regional Administrator, Region IX.
