5a2. BACT/LAER Determination

The BACT/LAER determination for this degreasing operation is an airless vapor degreaser. The permit limit shown in Item (5a1) is the maximum allowable PERC mass emission rate and concentrations from the degreasing operation. A continuous emissions monitoring at the outlet of the carbon bed record concentrations of PERC. (See Item 6 - Comment)
