July 7, 1980 PSD Applicability: Industrial Scrap Processing Company 2.12
In order to avoid PSD review an industrial processing plant would like to reduce its potential to emit with limited hours of operation of its shredder. The plant has 4 diesel engines, two which generate electricity for the plant and two which drive the shredder. Under the June 19, 1978 PSD regulation, potential to emit may include limitations on hours of operation, if the limitations are included in enforceable permit conditions. Limited hours of operation could be placed on the shredder in a 51.18 permit. The potential to emit of the source would then include the design capacity of the two engines which drive the shredder, including limited hours of operation, and the maximum design capacity of engines which generate plant electricity without hour limitations. These engines would not include limitations since they can operate independently from the shredder.
