IDAHO FALLS, Idaho – The Accelerated Retrieval Project I (ARP I), an effort to identify and exhume specific buried waste from a waste repository at the DOE Idaho National Laboratory (INL) Site, began in January 2005.

DOE, the Environmental Protection Agency (EPA) and state of Idaho signed a record of decision to clean up a pit within a waste repository at the DOE Idaho National Laboratory Site using a chemical extraction process, which later proved unsuccessful.

Environmental monitoring near a waste repository originally named the “burial ground” at the Idaho National Laboratory (INL) Site officially began in 1960 when the U.S. Geological Survey (USGS) began drilling wells at the landfill perimeter.

Following several buried waste exhumation projects in the 1970s, the DOE Idaho National Laboratory (INL) Site tested technologies to allow for a larger waste retrieval effort and attempt to minimize the spread of contaminated soil.

Just months after the Experimental Breeder Reactor-I began generating electricity in December 1951 in a historic first, the Idaho National Laboratory (INL) Site opened its first waste repository on the 890-square-mile Atomic Energy Commission (AEC) site.
DOE EM and State of Idaho officials gathered at the Idaho National Laboratory (INL) Site to mark the completion of a high-priority cleanup project that helps protect the Snake River Plain Aquifer and maintains a commitment with the state of Idaho.

Federal and contractor leadership serving on a panel at the 2022 Waste Management Symposia last week discussed the progress of liquid waste treatment facilities at three EM sites as they work to meet cleanup commitments.

EM crews at the DOE Idaho National Laboratory Site recently retrieved the last of the Advanced Test Reactor’s spent nuclear fuel elements from a water-filled storage basin and transferred them to a nearby dry-storage facility.

Crews at the DOE INL Site are operating the final test run of the Integrated Waste Treatment Unit (IWTU), running waste simulant through the facility to ensure the plant’s performance and personnel proficiency for upcoming radiological operations.

EM is set to deactivate and demolish the prototype for a reactor plant used for the first nuclear-powered submarine, a major step toward advancing environmental cleanup at the DOE's Idaho National Laboratory (INL) Site.
