RECOMMENDATIONS That the Air Resources Board (ARB) finds the ozone control plan for the Monterey/Santa Cruz Counties portion of the North Central Coast nonattainment area conditionally acceptable for submission to the Environmental Protection Agency (EPA) as a 1979 SIP revision. Staff has defined additional actions which should be taken by Monterey/Santa Cruz governmental agencies to satisfy the requirements for an acceptable 1979 SIP submission. SUMMARY The ARB is the state agency responsible for preparing and adopting the SIP for submission to the EPA. The nonattainment plan under consideration was prepared by the Association of Monterey Bay Area Governments in cooperation with a number of city, county, and state governmental agencies in response to Sections 171 through 176 of the Clean Air Act. An approvable 1979 SIP revision for a designated nonattainment area must demonstrate the attainment of NAAQS for criteria pollutants no later than December 31, 1982, except that extension may, under specified conditions, be requested to December 31, 1987 for ozone and carbon monoxide. The North Central Coast Basin, of which Monterey and Santa Cruz Counties are a portion, has been designated nonattainment for ozone only. The plan consists of a set of industrial, motor vehicle, and transportation control measures to be developed and implemented by local, state, and federal government agencies. Some of these measures are targeted for timely adoption as rules of the Monterey Bay Unified Air Pollution Control District. Other measures will continue to be studies and implemented at a later date. ARB staff finds that the Monterey/Santa Cruz nonattainment plan will, with changes, meet the Clean Air Act requirements for a 1979 SIP submission. The staff questions the ability of the plan to project attainment and maintenance of the ozone standards by and beyond 1982 in view of the predicted population and industrial growth in the area. Staff identifies additional actions which are needed to assure continued compliance with the requirements of the Clean air Act and recommends that an extension beyond 1982 is needed to assure attainment and maintenance of the ozone standard.
