Revisions to the California State Implementation Plan, Northern 
Sierra Air Quality Management District

AGENCY: Environmental Protection Agency.

ACTION: Proposed rule.


SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
approve a revision to the Northern Sierra Air Quality Management 
District (NSAQMD) portion of the California State Implementation Plan 
(SIP). The submitted SIP revision contains the District's demonstration 
regarding Reasonably Available Control Technology (RACT) requirements 
for the 1997 8-hour ozone National Ambient Air Quality Standards 
(NAAQS). The submitted SIP revision also contains negative declarations 
for volatile organic compound (VOC) source categories for the NSAQMD. 
We are proposing to approve the submitted SIP revision under the Clean 
Air Act as amended in 1990 (CAA or the Act). We are taking comments on 
this proposal and plan to follow with a final action.

DATES: Any comments on this proposal must arrive by May 13, 2015.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2014-0832, by one of the following methods:

    Instructions: All comments will be included in the public docket

including any personal information provided, unless the comment

whose disclosure is restricted by statute. Information that you

SUPPLEMENTARY INFORMATION: This proposal addresses the revisions to the 
NSAQMD portion of the California SIP. In the rules and regulations 
section of the Federal Register, we are approving the SIP revision 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 proposal. 
Please note that if we receive adverse comment on a specific provision 
of this SIP revision and if that provision may be severed from the 
remainder of the SIP revision, we may adopt as final those provisions 
of the SIP revision 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: February 12, 2015.
Alexis Strauss,
Acting Regional Administrator, Region IX.
