This section contains key historical documents related to the overall environmental investigation, design and execution of the remedy.

 

  • Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) (1980)
    • The Comprehensive Environmental Response, Compensation and Liability Act is the federal legislation governing hazardous waste cleanup site

     

    • Remedial Investigation and Endangerment Assessment/Feasibility Study (RI/EA/FS) 
      • The U.S. Army completed a systematic investigation of site contamination in accordance with the federal Comprehensive Environmental Response Compensation and Liability Act (CERCLA). The study was conducted to determine the nature and extent of environmental contamination and to develop and evaluate cleanup alternatives. The reports comprising the RI/EA/FS can be found here.
    • Federal Facility Agreement (FFA) (1989)
      • Signed by the U.S. Army, Shell, EPA, and Department of Justice, the FFA established a framework for completing high-priority cleanup projects (known as Interim Response Actions) while the overall framework for the remedy was developed. The FFA also outlined procedures for dispute resolution among the parties.    

    •  RMA National Wildlife Refuge Act (1992)
      • Passed by the U.S. Congress, the Refuge Act designated roughly 15,000 acres of the RMA as a future national wildlife refuge. The legislation enabled the U.S. Fish and Wildlife Service to manage wildlife and public use on the Arsenal while the U.S. Army completed the environmental cleanup. The bill also allowed the U.S. Department of Justice to transfer ownership of the land to the U.S. Department of the Interior once the EPA certified that cleanup actions were complete.

       

    •  RMA Off-Post Operable Unit Final Record of Decision (1995)
      • The Off-Post Record of Decision (ROD) is the final cleanup plan for the off-post contamination areas. The Off-Post ROD defines the off-post areas, describes the site conditions and risks, presents the selected remedial action, describes the legal requirements governing the cleanup of the off-post areas and explains the basis and purpose of the selected remedy.
    • Record of Decision for the On-Post Operable Unit (1996) 
      • The On-Post ROD is the final cleanup plan for the RMA. It provides the framework, purpose and overall rationale for the remedial actions to be accomplished at the RMA. It also includes a history, description and evaluation of the extent of and risks posed by contamination of all areas covered by the remedy. Most remedial actions are divided by media into the following categories: groundwater, structures and soils. Additional components of the ROD include acquisition of an alternative water supply for South Adams County, a Medical Monitoring Program, continued operation of the CERCLA Wastewater Treatment Plant, continued biota monitoring, provisions for treatment of unexploded ordnance (UXO), and provisions for disposal of wastes in the Corrective Action Management Unit (CAMU) Landfill.
    • NPL Partial Deletion: RMA Surface Deletion Area of On-Post Operable Unit (2004)
      • The Surface Deletion Area of the On-Post OU comprises approximately 123 acres (0.2 square miles) of the northern and southern perimeter of RMA. This partial deletion pertained to the surface (soil, surface water, sediment) and structures media only and excluded the groundwater media of the Surface Deletion Area.
