Corpus Christi Army Depot
A system was installed in April of 1994 that replaced the current solvent-based degreasers and parts washers. The old equipment used 1,1,1 Trichloroethane (TCE) which is a hazardous waste.
The installation of ultrasonic cleaning equipment replaced a process that ceased production as of December 31, 1995. CCAD has experienced lower operating costs since the implementation of this equipment.
Reduced or eliminated hazardous wastes from cleaning units that used chlorinated solvent degreasers and cleaners. TCE is a volatile solvent resulting in a high evaporation rate and release of volatile organic compounds (VOC). The removal of this substance eliminates a Class I ozone-depleting substance.
