The U.S. Army Environmental Command is the program manager for the Army's Active Installation Defense Environmental Restoration Program (DERP). DERP was formally established by Congress in 1986 and provides for the cleanup of Department of Defense (DoD) sites under the jurisdiction of the Secretary of Defense. The Army has two restoration programs under DERP at active/operating Army installations, the Installation Restoration Program (IRP) and the Military Munitions Response Program (MMRP). The IRP is a comprehensive program to identify, investigate and clean up hazardous substances, pollutants, and contaminants at active/operating Army installations. The MMRP addresses non-operational range lands that are suspected or known to contain unexploded ordnance (UXO), discarded military munitions (DMM) or munitions constituent (MC) contamination. Eligible sites include those contaminated by past defense activities that require clean up under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) as amended by Superfund Amendments and Reauthorization Act (SARA) and certain corrective actions required by the Resource Conservation Recovery Act (RCRA).
