IAAAP Administrative Record, required by the Code of Federal Regulations, is a compilation of documents that track the discovery, investigation and remedy selection for environmental clean-up activities under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). It also provides a mechanism for public participation. The documents contained in the Administrative Record were used as the basis for the selection of a response action. All hard copies of the Administrative Record reside at the installation.
The CERCLA process is a multi-step, science-based approach to addressing contaminated sites, ensuring both public and environmental protection. It also involves significant public participation and collaboration with various stakeholders. CERCLA documents are grouped by Operable Units with similar/same contamination.
For a complete list of every document, download the Administrative Record Index – April 2026.

If contamination is suspected or identified, the RI/FS phase involves a more comprehensive investigation. The RI includes extensive sampling and analysis to determine the nature and extent of contamination. A risk assessment, including both human health and ecological risk assessments, is conducted to determine the significance of the contamination. The FS evaluates various cleanup alternatives, considering factors like feasibility, effectiveness, cost, and environmental impact.

Removal Action (RA)
If immediate action is needed to address an imminent threat to human health or the environment, a removal action may be taken before the RI/FS is fully completed. This may involve containing or removing contaminates.
Remedy Selection and Decision Making
{Community Involvement}
Following the RI/FS, a Proposed Plan (PP) is developed, presenting the preferred cleanup alternative for public review and comment. A Record of Decision (ROD) or Decision Document (DD) is then issued, formally documenting the selected remedy.

If contamination is suspected or identified, the RI/FS phase involves a more comprehensive investigation. The RI includes extensive sampling and analysis to determine the nature and extent of contamination. A risk assessment, including both human health and ecological risk assessments, is conducted to determine the significance of the contamination. The FS evaluates various cleanup alternatives, considering factors like feasibility, effectiveness, cost, and environmental impact.

Formerly Utilized Sites Remedial Action Program (FUSRAP)
FUSRAP has the mission of protecting public health and the environment by removing low-level radioactive contamination generated by activities of the Manhattan Engineer District and the Atomic Energy Commission (MED/AEC) during the development of atomic weapons in the 1940s and 1950s. FUSRAP has a separate Federal Facility Agreement Under CERCLA Section 120, Administrative Docket Number: CERCLA-07-2005-0378.
FUSRAP also cleans RDX at Line 1. Documents for this project are under OU-1 and FUSRAP documents for OU-1 are located here:

Remedial Investigations/Feasibility Study (RI/FS)
{Site Characterization}
If contamination is suspected or identified, the RI/FS phase involves a more comprehensive investigation. The RI includes extensive sampling and analysis to determine the nature and extent of contamination. A risk assessment, including both human health and ecological risk assessments, is conducted to determine the significance of the contamination. The FS evaluates various cleanup alternatives, considering factors like feasibility, effectiveness, cost, and environmental impact.

Removal Action (RA)
If immediate action is needed to address an imminent threat to human health or the environment, a removal action may be taken before the RI/FS is fully completed. This may involve containing or removing contaminates.
Remedy Selection and Decision Making
{Community Involvement}
Following the RI/FS, a Proposed Plan (PP) is developed, presenting the preferred cleanup alternative for public review and comment. A Record of Decision (ROD) or Decision Document (DD) is then issued, formally documenting the selected remedy.
Preliminary Assessment/Site Inspection (PA/SI)
{Site Assessment}
The initial phase involves reviewing existing information, such as historical records and field visits, to determine if a release or threat of a release of hazardous substances has occurred. Limited sampling may be conducted to identify possible contamination sources.
