The Naval Aviation Depot (NADEP) in Jacksonville employs over 2,700 people in a wide variety of jobs. The NADEP is an industrial facility commissioned by the Navy to perform in depth rework, repair, and modification of aircraft, engines, and aeronautical components.
A special REWRAP task force assisted NADEP in categorizing the numerous processes used at the Station. In the course of this analysis, they uncovered pollution prevention opportunities in parts cleaning.
NADEP JAX has found that aqueous detergents used in a parts washer can be implemented to replace about 80% of their vapor degreasers operators. The REWRAP crew analyzed the cleaning processes that accounted for about 60% of 1,1,1-trichloroethane usage on the base. Implementation of the new technology is currently underway at the NADEP. The largest vapor degreaser used at the Depot was the first to be replaced. The savings from this one change was $172,487 per year.
In many manual cleaning steps throughout the base, less damaging and less expensive substitutes for ozone-depleting CFCs were found to be available. The combined savings from reduced raw material purchases and avoided disposal costs were $116,100 per year. These changes also prevented the release of over 25,000 pounds of CFC's into the environment per year.
Additional waste reduction initiatives have been implemented at other NADEP activities and are slated to be implemented at Jacksonville. These include substitute non-hazardous material for hazardous paint stripping, chromic acid strip, permanganate, corrosion inhibitor, carbon remover and miscellaneous wipe solvents. These changes have the potential for a cost savings of $615,000. The total cost savings at the Jacksonville NADEP ultimately will be approximately $904,000 per year.
The Department of Defense is committed to reducing waste in significant amounts. The waste reduction measures implemented at Jacksonville NAS also will be incorporated at the other five NADEPs throughout the country.
