Corpus Christi Army Depot

Year Submitted: 2003

Process: Parts Cleaning

Industry: Military

Wastes Reduced: Solvent

Substance: TCE

Equipment: Aqueous Cleaner

Location: Corpus Christi TX

No. of employees: 3500

Contact: Chuck Gawanes

Phone: (512) 939-4170



Description:

A system was installed in December of 1994 that reduced the amount of hazardous wastes generated by solvent-based degreasers and parts washers. The old equipment used 1,1,1 Trichloroethane (TCE) which is a hazardous waste.

P2 Application:

The installation of 6 agitated aqueous units and 7 high pressure aqueous spray units replaced a process that ceased production as of December 31, 1995. CCAD has experienced lower operating costs since the implementation of this equipment.

Environmental Benefits:

The system reduced or eliminated hazardous wastes from cleaning units that used chlorinated solvent degreasers and cleaners. TCE is a volatile solvent and is considered an ozone depleting organic compound. The removal of this substance eliminates a Class I ozone depleting substance and reduces hazardous waste volumes.

Details of Reductions

Additional Information :

The initial capital costs were $577,000 with a yearly savings of $248,000. The savings are from the reduction of hazardous waste regulations and disposal. The payback period is approximately 2.3 years.
