November 16, 2007 Mr. Wayne Nastri Regional Administrator Region 9 U.S. Environmental Protection Agency 75 Hawthorne Street San Francisco, California 94105
Dear Mr. Nastri: The Air Resources Board (ARB) is submitting to the U.S. Environmental Protection Agency (U.S. EPA) the adopted State Strategy for California's 2007 State Implementation Plan (State Strategy) as a revision to the California State Implementation Plan (SIP.) The State Strategy is a comprehensive strategy designed to attain federal ozone and fine particulate matter (PM2.5) air quality standards through a combination of technologically feasible, cost-effective, and far reaching measures. This submittal meets Clean Air Act requirements, and ARB requests U.S. EPA's timely approval. The State Strategy,, in combination with local actions, would provide the emission reductions necessary to the meet 8-hour ozone standard in California's two most challenging regions -- the South Coast Air Basin and the San Joaquin Valley. The State Strategy also provides reductions needed for PM2.5 attainment in the South Coast and expected to be necessary for the San Joaquin Valley. Finally, the State Strategy is necessary for attainment of the ozone standard, in whole or part, for the Sacramento 

### region, Ventura, and several locations downwind of urban areas. The submittal today includes enforceable emission reduction commitments in the South Coast (plus the Coachella Valley) and San Joaquin Valley. ARB will submit any emission reduction commitments needed for other regions of the State from the State Strategy with the regional SIPs for those areas. This submittal includes seven copies of the following materials. 1. The Proposed State Strategy for California's 2007 State Impiementation Plan (release date April 26, 2007) and Appendices A-G (release date May 7, 2007.) Appendix H is not part of this submittal.

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: hjfp://vvww.arb.ca.gov
