Mr. Jared Blumenfeld Regional Administrator Region 9 U.S. Environmental Protection Agency 75 Hawthorne Street San Francisco, California 94105

Dear Mr. Blumenfeld:

The Air Resources Board (ARB) is submitting to the U.S. Environmental Protection Agency (U.S. EPA) the 2009 Sacramento Regional 8-Hour Ozone Attainment and Reasonable Further Progress Plan — 2013 SIP Revisions (2013 Update). This submittal revises the California State Implementation Plan (SIP) for the 1997 8-Hour Ozone National Ambient Air Quality Standard (NAAQS) for the Sacramento Metropolitan Nonattainment Area (Sacramento Nonattainment Area) originally adopted and submitted in 2009. The Sacramento Metropolitan Air Quality Management District (SMAQMD) adopted the 2013 Update on September 26, 2013, and ARB approved its submittal as a SIP revision on November 21, 2013.

The 2013 Update submittal consists of two hard copies and two electronic copies on compact discs of the following items.

The SMAQMD transmittal package, including: A. November 20, 2013 letter from Larry Greene, SMAQMD Executive Officer, to Mr. Richard W. Corey, ARB Executive Officer. B. 2013 Update proposal letter from Larry Greene to the SMAQMD Board. C. SMAQMD Board Resolution 2013-026 adopting the 2013 Update. D. SMAQMD Staff Report dated September 26, 2013. E. Response to Comments on the 2013 Update, September 2013. F. Proof of Publication for Notices of Public Hearings. G. Changes to the Plan Following April 22, 2013 Public Release. H. Final 2013 Update including Appendices A through I, November 2013.

The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. For a list of simple ways you can reduce demand and cut your energy costs, see our website: http://www.arb.ca.qov

II. Materials related to ARB adoption, including: A. ARB Resolution 13-39 adopting the 2013 Update as a revision to the SIP for the Sacramento Nonattainment Area. B. ARB Staff Report, Proposed Revisions to the 8-Hour Ozone State 

### Implementation Plan for the Sacramento Federal Nonattainment Area. C. Transcript for ARB November 21, 2013 Public Meeting to consider approval of the 2013 Update. III. SIP Submittal Checklist. IV. Changes to the ARB Staff Report Following October 22, 2013 Public Release.

The 2013 Update includes a revised emission inventory that accounts for the implementation of control measures adopted through 2011, the effects of the recession, and updated transportation activity projections provided by the Sacramento Area Organization of Governments.

The 2013 Update includes on-road motor vehicle emission budgets for the years of 2014, 2017 and 2018. To ensure that any future updates to these budgets are used expeditiously in the conformity process, we request that U.S. EPA allow budgets to be 

### replaced upon a finding of adequacy. To accomplish this, we ask U.S. EPA to limit its approval of the budgets submitted today to last only until the effective date of future U.S. EPA adequacy findings for replacement budgets. We anticipate Board action on new budgets as part of the 2016 SIP process to address the 2008 ozone standard in July 2016.

ARB is committed to working with U.S. EPA staff to provide any additional clarifying information needed. If you have any questions, please call Ms. Lynn Terry, Deputy Executive Officer, at (916) 322-2739, or have your staff contact Ms. Sylvia Vanderspek, Chief, Air Quality Planning Branch, at (916) 324-7163.

Sincerely,
