5.1 AIR QUALITY the state's ambient air quality standards;to review the operations of the local air pollution control districts; and to review and coordinate preparation of the SIP for achievement of the federal ambient air quality standards (California Health&Safety Code (H&SC) §39500 et seq.). When the state's air pollution statutes were reorganized in the mid-1960s,local air pollution control districts (APCDs) were required to be established in each county of the state (H&SC §4000 et seq.). There are three different types of districts: county,regional,and unified. In addition, special air quality management districts (AQMDs),with more comprehensive authority over non-vehicular sources as well as transportation and other regional planning responsibilities,have been established by the Legislature for several regions in California (H&SC§40200 et seq.). APCDs and AQMDs in California have principal responsibility for: • Developing plans for meeting the state and federal ambient air quality standards; • Developing control measures for non-vehicular sources of air pollution necessary to achieve and maintain both state and federal air quality standards; • Implementing permit programs established for the construction,modification, and operation of sources of air pollution; and • Enforcing air pollution statutes and regulations governing non-vehicular sources,and for developing employer-based trip reduction programs. Each level of government has adopted specific regulations that limit emissions from stationary combustion sources,several of which are applicable to this project. 5.1.6.1 Federal LORS The EPA implements and enforces the requirements of many of the federal environmental laws. The federal Clean Air Act, as most recently amended in 1990,provides EPA with the legal authority to regulate air pollution from stationary sources such as the project. EPA has promulgated the following stationary source regulatory programs to implement the requirements of the 1990 Clean Air Act: • Standards of Performance for New Stationary Sources (NSPS) • National Emission Standards for Hazardous Air Pollutants (NESHAPS) • Prevention of Significant Deterioration (PSD) • New Source Review (NSR) • Title IV: Acid Deposition Control • Title V: Operating Permits National Standards of Performance for New Stationary Sources Authority: Clean Air Act§111,42 USC§7411;40 CFR Part 60,Subpart KKKK Purpose:Establishes standards of performance to limit the emission of criteria pollutants (air pollutants for which EPA has established national ambient air quality standards) from new or modified facilities in specific source categories. The applicability of these regulations depends on the equipment size;process rate; and date of construction,modification, or reconstruction of the affected facility. The project is subject to the following NSPS: SAC/371322/082410013(LEC_5.1_AIR_QUALITY.DOC) 5.143
