Energy without pollution control

Figure 3. Energy and energy cost without pollution control...

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/...
