AEC Atomic Energy Commission – The AEC was replaced by the Energy Research and Development Administration, along with the Nuclear Regulatory Commission. ERDA later became the Department of Energy.

Administrative Record Information sources – such as the documents used to select a cleanup method, documents regarding site activities and general Superfund information – are placed in the Administrative Record or Administrative Record File. The information is available to the public so that they may make informed comments on the selection of a final site remedy.

CERCLA The Comprehensive Environmental Response, Compensation and Liability Act of 1980 is the main law governing cleanup of FUSRAP sites. In 1986, major changes to this federal law were enacted with the passing of the Superfund Amendments and Reauthorization Act (SARA), which authorized the study and cleanup of uncontrolled hazardous-waste sites.

CIP Community Involvement Plan – Once known as a Community Relations Plan (CRP).

Clean Air Act If performing an excavation that may release contaminated dust particles into the air, FUSRAP may need to comply with the requirements of the Clean Air Act. In other situations, FUSRAP may need to comply with different laws, such as the Toxic Substances Control Act, the Clean Water Act and/or the Safe Drinking Water Act as well as many other federal, state and local standards that may also apply to the FUSRAP cleanup.

DOE U.S. Department of Energy – In October 1997, the execution of FUSRAP was transferred from the Department of Energy to the U.S. Army Corps of Engineers under the Energy and Water Development Appropriations Act of 1998. Once a site is removed from the list of active FUSRAP sites, DOE's Office of Legacy Management, once known as the Office of Long-term Stewardship, takes on the task of long-term site stewardship.

EMDAR Annual Environmental Monitoring Data/Analysis Report – FUSRAP scientists follow plans, guidelines and regulations to collect samples to monitor site conditions. Under FUSRAP’s Environmental Monitoring Program, they conduct activities to demonstrate compliance with regulations and the requirements of state or local permits. To conduct the monitoring, the FUSRAP team samples various media at FUSRAP Sites and documents the findings in the annual Environmental Monitoring and Data Analysis Report. An EMDAR provides the laboratory analytical results received during the previous year.

Energy and Water Development Appropriations Act – In October 1997, the execution of the Formerly Utilized Sites Remedial Action Program (FUSRAP) was transferred from the Department of Energy to the U.S. Army Corps of Engineers under the Energy and Water Development Appropriations Act of 1998. Since that transition was effected, the St. Louis Sites have fallen under the responsibility of USACE, St. Louis District.

IAAAP The Iowa Army Ammunition Plant is an active, government-owned, contractor-operated facility that occupies approximately 19,000 acres (about 30 square miles) in Des Moines County near Middletown in southeast Iowa. Located about 10 miles west of Burlington, Iowa, and the Mississippi River, IAAAP is under the command of the U.S. Army Joint Munitions Command, Rock Island.

IC Institutional Controls – According to the U.S. Environmental Protection Agency document Institutional Controls: A Guide to Planning, Implementing, Maintaining, and Enforcing Institutional Controls at Contaminated Sites, the EPA defines ICs as "nonengineered instruments, such as administrative and legal controls, that help to minimize the potential for exposure to contamination and/or protect the integrity of a response action. ICs typically are designed to work by limiting land and/or resource use or by providing information that helps modify or guide human behavior at a site. ICs are a subset of Land Use Controls (LUCs). LUCs include engineering and physical barriers, such as fences and security guards, as well as ICs."

LUCs help to minimize the potential for exposure to contamination and/or protect the integrity of a response action and are typically designed to work by limiting land and/or resource use or by providing information that helps modify or guide human behavior at a site." Institutional Controls are a subset of Land Use Controls (LUCs), according to the EPA document Institutional Controls: A Guide to Planning, Implementing, Maintaining, and Enforcing Institutional Controls at Contaminated Sites.
