Subject: Submittal of Reasonably Available Control Tech nology Revision to Western

Nevada County State Implementation Plan (RACT SIP) for transmittal to EPA

Dear Mr. Goldstene:

The Northern Sierra Air Quality Management District (NSAQMD) encompasses the California

counties of Nevada, Plumas and Sierra. Weste rn Nevada County was designated in 2004 as

nonattainment for the 1997 federal 8

- hour ozone standard, but has not yet been classified.

The federal Clean Air Act §172(c)(1) requires nonattainment areas to implement Reasonably

Available Control Technology (R ACT). §183 requires EPA to issue Control Techniques

Guidelines (CTGs) for identified categories of stationary sources, which serve to define RACT.

§182(b)(2)(A) requires states to submit State Implementation Plan (SIP) revisions addressing the

CTGs. Acc ordingly, the NSAQMD has adopted rules for all CTGs issued to date which apply to

sources that exist in the nonattainment area. In addition, the NSAQMD has previously submitted

Negative Declarations for all CTGs issued by EPA through 2007 that do not appl y to any sources

in the nonattainment area.

On April 25, 2011, the NSAQMD Board of Directors held a public hearing (no public comments

were received), following a public notice period of more than 30 days, at which the Negative

Declaration was approved for all 2008 CTGs that do not apply to any sources in the

nonattainment area. No CTGs have been issued since 2008, so with adoption of this Negative

Declaration it appears that all existing RACT requirements for the Western Nevada County

nonattainment are a have been fulfilled.

Pursuant to the requirements of 40 CFR Part 51, Appendix V, the NSAQMD is hereby

submitting:

1) The District’s Board

- adopted Negative Declaration as a RACT SIP Revision; 2) Proof of

public notice; and 3) Board resolution indicati ng adoption of the Negative Declaration.The NSAQMD requests that ARB transmit the enclosed Negative Declaration, as a RACT SIP

Revision, to EPA in fulfillment of RACT requirements under the Clean Air Act.

Please contact me (530

staff (530

Gretchen Bennitt,

Air Pollution Control Officer
