DATE: September 18, 2014 TIME: 9:00 a.m. PLACE: California Environmental Protection Agency Air Resources Board Byron Sher Auditorium 1001 I Street Sacramento, California 95814 This item will be considered at a two-day meeting ofthe Board, which will commence at 9:00a.m., September 18, 2014. This item is scheduled to be heard on the Board's Consent Calendar. All items on the Consent Calendar- unless removed upon the request ofa Board member or ifsomeone in the audience submits a request to speak card on that item- will be voted on by the Board at the beginning ofthe public meeting. The Clean AirAct (CAA) establishes planning requirements for areas that exceed the health-based National Ambient Air Quality Standards (NAAQS or standard). These nonattainment areas must develop and implement an approvable attainment plan that demonstrates how they will attain the standard by specified CAA deadlines. In 1987, U.S. EPA promulgated a national ambient air quality standard (standard) for particulate matter less than 10 microns (PM 10) at 150 micrograms per cubic meter (1Jglm3) for a 24-hour period and classified Mammoth Lakes as a nonattainment area. U.S. EPA required the District to develop an attainment plan that would include a control strategy and regulatory requirements to bring the area into attainment with the standard. The required plan was adopted by the District and the plan's control measures were adopted by the Town of Mammoth Lakes in December 1990. These control measures regulated the installation ofwoodstoves, established no burn days for fireplaces, instituted street sweeping, and incorporated planning measures to reduce vehicle miles traveled in the Town of Mammoth Lakes.Quality-assured air quality monitoring data collected in Mammoth Lakes show thatthe 24-hour PM 10 standard has not been exceeded since 1993

. Under provisions ofthe CAA, an area designated as nonattainment can be redesignated to attainment if, among other requirements, the U

.S

. EPA has fully approved a SIP conforming with the requirements ofthe CAA
