The Waste Reduction Evaluation at Federal Sites (WREAFS) Program consists of a series of demonstration and evaluation projects for waste reduction conducted cooperatively by EPA and various parts of the Department of Defense (DOD), Department of Energy (DOE), and other Federal agencies. The objectives of the WREAFS Program include: (1) conducting waste minimization workshops; (2) performing waste minimization opportunity assessments; (3) demonstrating waste minimization techniques or technologies at Federal facilities; and (4) enhancing waste minimization benefits within the Federal community. One of the WREAF sites chosen for performance of a waste reduction assessment is the Philadelphia Naval Shipyard (PNSY). This Federal facility specializes in revitalizing and repairing ships already in fleet. A wide range of industrial processes are performed at the PNSY, many of which generate wastes. The project focused on the processes and wastes of operations related to aluminum cleaning, spray painting, and bilge cleaning. Seven waste minimization options were evaluated during the project using EPA's Waste Minimization Opportunity Assessment Manual.
