4.6 Air Quality The SJVAPCD limits emissions of, and public exposure to,toxic air contaminants through a number of programs to include the risk reduction program. District Policies 1905,Risk Management Policy for Permitting New and Modified Sources, and 1910, Toxic Best Available 1 60 Control Technology for New and Modified Diesel Internal Combustion Engines provide guidelines on permitting sources that emit toxic air contaminants(also referred to interchangeably by the district as hazardous air pollutants). 1110 The potential for new and modified stationary sources to emit toxic air contaminants is reviewed by the SJVAPCD's Permit Services Division, which implements the SJVAPCD's Risk IN. Management Policy. The District's Regulation VII pertains specifically to toxic air contaminants. Toxic air contaminant emissions from stationary sources are limited by: • SJVAPCD adoption and enforcement of rules aimed at specific types of sources known to emit toxic air contaminants; • Implementation of the Air Toxics "Hot Spots"Program; and • Implementation of the Federal Title III Toxics program. Federal Regulations for Criteria Pollutants Standards of Performance for New Stationary Sources Section 111 of the California Ambient Air(CAA)Standards of Performance of New Stationary Sources requires EPA to establish federal emission standards for source categories that cause or .. contribute significantly to air pollution.These standards are intended to promote use of the best air pollution control technologies,taking into account the cost of such technology and any other non-air quality, health, and environmental impact and energy requirements. Prevention of Significant Deterioration Prevention of Significant Deterioration(PSD)regulations were first promulgated by the EPA ` (40 CFR 52)to prevent air quality degradation in those areas where criteria air pollutant concentrations are below the ambient standards(i.e., attainment areas).Exceedance of a PSD ` trigger level requires a demonstration by dispersion modeling that the emissions will not interfere with the attainment or maintenance of any NAAQS at the point of maximum impact and will not cause an exceedance of a PSD increment. Title V Federal Operating Permit (Title V) Title V of the 1990 CAA Amendments requires all major sources and some minor sources of air ` pollution to obtain an operating permit. A Title V permit grants a source permission to operate. The permit includes all air pollution requirements that apply to the source, including emissions ` limits and monitoring,record keeping, and reporting requirements. It also requires that the source report its compliance status with respect to permit conditions to the permitting authority. Under Title V of the CAA, any source that emits or has the potential to emit 100 tons per year or more V of any criteria air pollutant is a major source and must obtain a Title V operating permit. •• RMC Pacific Vernalis Quarry Mining and Reclamation Project 4.6-13 ESA 1203015 Draft Environmental Impact Report May 2006
