Hazardous Air Pollutants. Tide 3 of the CAAA of 1990 addresses the release of hazardous air poUutants (HAPs) by requiring both the identification of major stationary sources and area source categories for 189 toxic chemicals and the promulgation of control standards. Major sources of air toxics, also referred to as HAPs, include any stationary source or group of sources emitting 10 or more tons/yr of any single Hsted toxic chemical or 25 tons/yr of a combination of any Hsted toxic. Area sources of HAPs include smaller plants that emit less than the 10 or 20 tons/yr thresholds. The major sources of HAPs are typically industrial faciHties. However, Tide 3 requites the EPA to study potential health affects associated with emissions of HAPs from electric UtiHty boilers (11). 

The pollutants, source categories, and affected facilities for which the United States has established New Source Performance Standards are listed in Table 25-1. Certain categories listed in Table 25-1 are subject to U.S. Prevention of Significant Deterioration (of air quality) (PSD) review if their emission potential of a regulated pollutant exceeds 100 tons per year. In... 

The law includes a list of 189 toxic air pollutants of which emissions must be reduced. The list of source categories includes (1) major sources emitting 10 tons/year of any one, or 25 tons/year of any combination of those pollutants and (2) area sources (smaller sources, such as dry cleaners). 

NESHAP National Emissions Standards for Hazardous Air Pollutants emission standards for specific source categories that emit or have the potential to emit one or more hazardons air pollutants the standards are modeled on the best practices and most effective emission reduction methodologies in use at the affected facilities. 

EPA regulates 3,3 -dichlorobenzidine under the Clean Air Act (CAA) and has designated 3,3 -dichloro-benzidine as a hazardous air pollutant (HAP) (EPA 1994 U S. Congress 1990). The major source category for which the national emissions standards for new stationary sources are applicable to 3,3 -dichlorobenzidine emissions is the synthetic organic chemicals manufacturing industry (SOCMl)—equipment leaks (EPA 1994). 

In this chapter the air quality of the EMB is examined in terms of particulate pollution while the characteristic emissions of the basin are explored to further understand the source categories affecting the region.
