U.S. Army Corps of Engineers excavating contamination at the St. Louis Downtown sites resulting from the Manhattan Project.

From 1942 to 1973, uranium processing for the federal government’s early nuclear weapons program and related activities were conducted in St. Louis City and North St. Louis County. The Manhattan Engineer District, and later the Atomic Energy Commission, both predecessors of the U.S. Department of Energy (DOE) were responsible for these activities. The processing and management practices conducted during that time resulted in soil, sediment, surface water and groundwater contamination.

In 1974, the Formerly Utilized Sites Remedial Action Program (FUSRAP)(link is external) was created to identify, investigate, clean up and manage sites that were part of the nation’s early atomic energy and weapons program. The St. Louis Downtown Site (SLDS), the St. Louis Airport Site (SLAPS), the Hazelwood Interim Storage Site and former Futura Co. (HISS/FUTURA) and properties contaminated in association with these sites were designated for FUSRAP in the St. Louis area. The U.S. Army Corps of Engineers (USACE)(link is external) has been in charge of FUSRAP management since 1997, with the U.S. Environmental Protection Agency (EPA)(link is external) providing primary regulatory oversight. 

Agency Roles

The department's Federal Facilities Section provides oversight for investigating and cleaning up hazardous chemical and radiological substances at federal facilities, including the St. Louis FUSRAP sites. The department's Federal Facilities Section also provides guidance that ensures site activities follow state and federal environmental laws and regulations. The department is coordinating with EPA and may provide independent oversight as needed.

The USACE's FUSRAP St. Louis District(link is external) is responsible for finding and remediating radiological contamination generated by activities of the Manhattan Engineer District and the Atomic Energy Commission during development of the atomic weapons in the 1940s and 1950s. FUSRAP responsibilities include responding to public concerns of site related contamination. If concerns continue to exist after contacting FUSRAP, the Missouri Department of Natural Resources currently has limited funding to investigate concerns of exposure to radioactive waste upon written request by a local governing body. According to Missouri Revised Statue 260.558, RSMo, the local governing body must provide a written request that includes a specified area of concern within their jurisdiction along with any supporting documentation related to the concern. Any request for investigation should be directed to the Missouri Department of Natural Resources' Federal Facility Section.
