Dear Mr. Blumenfeld: 

Edmund G. Brown Jr. 

Governor 

Enclosed is a revision to the California State Implementation Plan (SIP) that consists of 

Northern Sonoma Air Pollution Control District (District) rules modified on 

November 14, 2014 to conform to U.S. Environmental Protection Agency (U.S. EPA) 

requirements that were outlined in its partial disapproval of California's Infrastructure 

SIP. The rules are identified in Enclosure A and will be incorporated in Infrastructure 

SIP. 

Also enclosed is the Air Resources Board Executive Order S-14-014 adopting the 

District's rules as revisions to the SIP. To meet the U.S. EPA criteria for determining 

that rule submittals are administratively and technically complete, we have enclosed a 

SIP submittal checklist. We have also enclosed an evaluation of the effects of the rule 

on emissions, evaluation of the rule's consistency with 40 CFR 51, and other supporting 

documentation provided to us by the District. One compact disc and one paper copy, 

each containing the revision, are enclosed. 

If you have any questions, please have your staff contact Ms. Karen Magliano, Acting 

Chief, Air Quality Planning and Science Division, at (916) 322-5350 or by email at 

kmaglian@arb.ca.gov. 

Sincerely,
