ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R09-OAR-2012-0180; FRL-9652-3]

Revisions to the California State Implementation Plan, Yolo-
Solano Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to the Yolo-Solano Air 
Quality Management District portion of the California State 
Implementation Plan (SIP). These revisions concern particulate matter 
(PM) emissions from any source that emits visible air contaminants. We 
are proposing to approve and rescind 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 May 18, 2012.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2012-0180, 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. 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 section.

FOR FURTHER INFORMATION CONTACT: Christine Vineyard, EPA Region IX, 
(415) 947-4125, vineyard.christine@epa.gov.

SUPPLEMENTARY INFORMATION: This proposal addresses the following local 
rules: Rule 2.3, Ringelmann Chart; 2.4, Exceptions (rescinded); Rule 
2.7, Wet Plumes (rescinded); Rule 2.11, Particulate Matter 
Concentrations; and Rule 2.12, Specific Contaminants. 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 this rule and if that 
provision may be severed from the remainder of the rule, we 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: March 8, 2012.
Jared Blumenfeld,
Regional Administrator, Region IX.
