This manual provides design guidelines that will aid U.S. Army Corps of Engineers Districts and Divisions in the selection of remedial actions at uncontrolled hazardous waste sites. These guidelines are to be used in support of the Department of Defense Environmental Restoration Program (DERP), the Formerly Used Defense Sites (FUDS) Program, Resources Conservation and Recovery Act (RCRA), support to U.S. Environmental Protection Agency (EPA) activities associated with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and the remediation of hazardous waste contamination at Civil Works sites.
