Superfund site and placed it on the National Priorities List in 1987. Site cleanup activities began in 1989 and continued through the 1990s. Groundwater and soil monitoring continues at the site. The U.S. Agency for Toxic Substances and Disease Registry (ATSDR) conducted a public health assessment of the site and concluded in 1992 that DDOU poses "no apparent public health hazard." Included in the site history was the storage of 2,328, 55-gallon drums of hazardous waste in 1993. This was part of a RCRA permit issued by the Utah Solid and Hazardous Waste Control Board. These drums were stored in a facility called the Conforming Storage Building. Storage of these materials ended in 1997, and the building was closed. As part of the transfer of ownership to the OLRA, two Finding of Suitability to Transfer (FOST) documents were developed and approved by state and federal agencies. A total of of uncontaminated ground were transferred to the OLRA. Further FOST activities are ongoing, and should eventually result in a nearly complete transfer of properties.
