Revisions to the California State Implementation Plan, Lake 
County Air Quality Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.


SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a revision to the Lake County Air Quality Management District 
(LCAQMD) portion of the California State Implementation Plan (SIP). 
This revision concerns the definition of hazardous air pollutants and 
particulate matter emissions from agricultural compression ignition 
engines. We are proposing to approve local rules under the Clean Air 
Act (CAA or the Act).

DATES: Any comments on this proposal must arrive by November 5, 2014.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2014-0412, 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 
    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

(415) 972-3248, perez.idalia@epa.gov.

SUPPLEMENTARY INFORMATION: This proposal addresses the following local 
rules: LCAQMD Section 228, Hazardous Air Pollutants (HAP), and LCAQMD 
Section 470, Air Toxics Control Measure for Emissions of Toxic 
Particulate Matter from In-Use Agricultural Compression Ignition 
Engines. 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 
either 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: May 30, 2014.
Jared Blumenfeld,
Regional Administrator, Region IX.
