Abstract : At the request of HQ AFLC/SGB, personnel from the USAFOEHL conducted an air emission survey of the exhaust from a C-5 brake reconditioning operation at Hill AFB UT from 13 July to 17 July 1987. These brakes contain beryllium disks and during the reconditioning process, beryllium particles are generated. The reconditioning operation consists of two processes which vent to individual stacks. The emissions for both stacks were well below the EPA standard for this kind of operation. The brake shop conducts a two part reconditioning operation on C-5 beryllium brake discs. This operation consists of an active wet grinding process and a wet dipping process. The reconditioning process is a cyclic operation for six hours per day and the shop operates only one shift per day. Each process is exhausted through its own stack and has no air pollution control equipment.
