station. The maximum 1 -hour CO concentration measured at the Anaheim station was 19 ppm (compared to the 20 ppm state standard). The state and federal lead standards were not exceeded at the Anaheim station. The one -hour state nitrogen dioxide standard (25 ppm) was exceeded on less than one percent of the days monitored at this station. The 24 -hour state sulfate standard (25 ug /m) was not exceeded at the Aaabeim station. Table 7 summarizes the health effects of air pollutants. Air Oualitv Manaeement Plan (AOMP) The Federal Clean Air Act and the State Lewis Air Qualitv Act require the preparation of a plan for the South Coast Air Basin (SCAB) which will demonstrate the attainment of both the federal and state air quality standards at the earliest date achievable (1987) using all reasonably available control measures. The AQMP, originally adopted in 1979 and revised by the 1982 Draft (adopted in October 1982), is the SCAB'S plan to meet federal and state air quality standards. A revision to the AQMP was approved by the South Coast Air Quality Management District, the Southern California Association of Governments, and the California Air Resources Board, in late 1989. The plan has not yet been approved by the United States Environmental Protection Agency (EPA). The 1989 AQMP identities the control measures available for implementation by 1993, as well as long range strategies to bring the basin into later compliance. These measures will meet the federal and state standards for nitrogen dioxide by 1996. The air basin is already in compliance with federal and state standards for lead. There will be continuous attainment of federal sulfur dioxide standards and state CO standards; however, violations will continue for particulates and ozone after the 2007 attainment deadline. Federal carbon monoxide standards are expected to be met by the year 1997. State sulfate standards, which are occasioaatly exceeded, will be addressed in the 1991 AQMP update, along with all other state air quality standards. Staff representatives of both the Southern California Association of Governments and the South Coast Air Quality Management District were contacted to determine how the new AQMP applies to this project. Their response was that the AQIvIP addresses only trans- portation projects of state -wide or region -wide significance, such as freeway and highway projects, new transportation corridors, mass transit Il11m] 75C -84
