Best available technology source category

USEPA and Envirodyne Engineers, Inc. Review of the Best Available Technology for the Rubber Processing Point Source Category, Technical Report No. 68-01-4673 US Environmental Protection Agency Washington, DC, 1978. 

The USEPA is responsible for creating and enforcing the NESHAPs for all hazardous air pollutant sources. The CAA states that new or existing major sources must have emission standards based on the maximum available control technology (M ACT) to reduce hazardous air pollutant emissions. The MACT standards are based on the performance of the best 12% of the control devices in the same source category. These MACT emissions requirements were extended in 1997 to cover wastewater biosolid incinerators at publicly owned treatment works (POTWs) that have the potential to discharge cadmium, lead, and mercury (Richman, 1997). 

PSD requirements are applicable to 28 categories of new or modified sources which have the potential to emit more than 100 tons of pollutants per year, and all other new or modified sources which have the potential to emit more than 250 tons of pollutants per year. 16/ While new or modified sources which are subject to PSD review may not be constructed without a permit, PSD permit requirements are somewhat less stringent than Part D permit requirements. For example, facilities in PSD areas must adopt "best available control technology," (BACT) 17/ an easier standard to meet than LAER required in Part D. For BACT takes into account factors such as "energy, environmental, and economic impact and other costs" on a case-by-case basis, none of which are considered in LAER. 18/...
