## ~O" ' Regional Administrator U . S. Environmental Protection Agency Region 9 75 Hawthorne Street San Francisco, California 94105 Dear Mr. Blumenfeld: Edmund G . Brown Jr. Governor

Enclosed is a revision to the California State Implementation Plan (SIP). This revision consists of the adopted Ozone Emergency Episode Plan (Plan) from the Placer County Air Pollution Control District (District). Also enclosed is Air Resources Board (ARB) Executive Order S- 15-005 adopting the Plan as a revision to the SIP . On October 23, 2014 , U . S . EPA proposed to partially disapprove portions of the 2014 California Infrastructure SIP including the District requirements relating to an emergency episode plan for ozone (79 FR 63350). This SIP submittal corrects the deficiency and allows U.S. EPA to move forward with approval of this portion of the California Infrastructure SIP. To meet the U . S . EPA's criteria for determining that rule submittals are administ ratively and technically complete, we have enclosed an evaluation of the rule ' s consistency w ith 40 CFR 51 and other supporting documentation provided to us by the D istrict. One compact disc and one paper copy, each containing the revision in t heir entirety, are enclosed.
