Intermittently from 1943 to 1951, the Herring-Hall-Marvin Safe Company, located in Hamilton, Ohio, fabricated slugs from rolled natural uranium metal stock for the Manhattan Engineer District and the U.S. Atomic Energy Commission.

In 1994, DOE designated the Hamilton Site for remediation under FUSRAP. DOE remediated areas of contamination identified on surfaces and in floor drains in the interior of the building in 1994 and 1995. DOE certified that the site complied with applicable cleanup criteria and standards in 1996 and released the property for unrestricted use.

No supplemental limits or institutional controls are in effect at the privately owned site, and DOE does not require on-site monitoring or surveillance. Legacy management activities consist of managing site records and responding to stakeholder inquiries.
