In recent years, the need for nuclear materials has decreased and the Department of Energy (DOE) has focused greater attention on cleaning up contamination left from past activities. The Office of Environmental Management (EM) within DOE is responsible for managing waste and cleaning up contamination at DOE sites across the nation. This collection of 40 EM Fact Sheets contains information on DOE and EM activities in technology development, facility transition and management, radiation in the environment, and related programs and activities. Three major sections contain fact sheets on laws and regulations, waste management, and environmental restoration. Regulations covered include the Resource Conservation and Recovery Act; the Comprehensive Environmental Response, Compensation, and Liability Act or "Superfund"; the National Environmental Policy Act; and additional statutes affecting DOE's Environmental Management Program. Other fact sheets contain definitions of waste management and environmental restoration and cover activities at DOE regional operations offices. Fact Sheets are a major component of EM's Public Participation Program, which attempts to educate stakeholders in DOE-related environmental issues. EM also sponsors educational programs, special topic workshops, and science units for schools. (LZ)
