# 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.

# 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.

Acting Regional Administrator, Region IX.
