Conflict with or obstruct implementation of applicable Air Quality Attainment Plan or Congestion Management Pian? Findin No Impact. Analysis: The project site is located within the South Coast Air Basin {SCAB). Air quality control in the SCAB is regulated by federal, state, and regional control authorities. The U.S. Environmental Protection Agency (EPA) is involved in local air quality planning through the Federal Clean Air Act (CAA), as recently amended by the Clean Air Act Amendments {CAAA) of 1990. At the state level, the California Clean Air Act of 1988 set air quality planning and regulatory responsibilities for the SCAB. The California Air Resources Board (ARB) is charged with the responsibility for coordinating efforts to attain and maintain ambient air quality standards. At the regional level, the South Coast Air Quality Management District (SCAQMD) has responsibility for preparing and periodically revising their Air Quality Management Plan {AQMP), which contains measures to meet state and federal requirements. The CAAA of 1970 established national ambient air quality standards (AAQS) with states retaining the option to adopt more stringent standards or to include other pollution species. Because California already had standards in existence before federal AAQS were established, and because of unique meteorological conditions in California, there is some diversity between state and federal standards currently in effect in California {see Table 1 }. The applicable Air Quality Attainment Plan in the project area is the South Coast Air Quality Management District (SCAQMD} 2007 Air Quality Management Plan {AQMP). Because construction ac#ivity is an ongoing existing activity in the Basin, emissions associated with construction activity are accounted for as part of the AQMP's existing regional inventory. The AQMP targets stationary sources and stationary source controls. The proposed project does not directly relate to adopted air quality standards because sewer lift stations are not considered stationary sources of air quality pollutants, as the Eift station would be powered by electricity and not fossil fuels. In addition, the AQMP does not contain emission reduction measures for such improvements. The proposed project a#so would not accommodate substantial growth in the area, both because the project area is largely built-out and because the project is merely removing and replacing an existing lift station. Therefore, because the proposed project is not considered a stationary source of air pollutants, does not involve an increase in population, housing, or employment, and because there are no air quality programs or regulations regarding sewer lift stations, the project would not have the potential Page 33 of 64 75E-37
