The U.S. Department of Energy (DOE) initiated the Formerly Utilized Sites Remedial Action Program (FUSRAP) in 1974 to address concerns about radiological conditions at locations where work was performed for the Manhattan Engineer District and the U.S. Atomic Energy Commission. The DOE Office of Legacy Management (LM) is responsible for 27 FUSRAP sites and will ultimately assume responsibility for more than 50 FUSRAP sites. DOE-LM assumed responsibility for 25 FUSRAP sites in 2004 and began an assessment of site conditions to ensure that complete site knowledge was preserved in DOE records and that the sites are and will remain protective of human health and the environment. For the assessment, site conditions were assumed to be dynamic. Therefore, the most restrictive site exposure scenarios were considered, as well as the implications for disturbing materials to which supplemental limits were applied. If conditions under these possible future scenarios were found to be protective, no use restrictions were needed. However, if future use or exposure scenarios could result in potential unacceptable risk, restrictions on site use were indicated. The assessment relied on access to documentation of site activities, characteristics, remedial action activities, remediated conditions, and land-use restrictions. In addition, an ongoing program of site visits commenced in 2005. DOE-LM assessed the level of knowledge and sought to identify and preserve site information for use by future custodians. DOE-LM has applied lessons learned in site management since 1989, when a formal DOE program was established to implement long-term surveillance and maintenance (LTS and M) activities. Former FUSRAP staff members with the DOE Office of Environmental Management also conveyed lessons learned. We present the assessment process that was used, the application of results, and a framework for evaluating LTS and M requirements for FUSRAP sites. (authors)
