The 300-acre Monticello Mill Tailings site is comprised of a 78-acre inactive uranium and vanadium milling operation and affected peripheral properties in Monticello, San Juan County, Utah. Surrounding land use is rural residential and agricultural. Milling of ore began in 1942, and a vanadium/uranium sludge product was produced onsite from 1943 to 1944. The mill was permanently closed in 1960, and the tailings piles were covered and vegetated. In 1972, 15,000 cubic yards of contaminated soil were excavated and disposed of on the onsite tailings piles. Site investigations from 1989 to 1990 identified the presence of onsite and offsite radioactively-contaminated soil and ground water, and elevated concentrations of metals within the tailings piles. The Record of Decision (ROD)addresses remediation of two Operable Units (OUs): the 78-acre Millsite area (OU1), and the 240-acres of peripheral properties (OU2). The primary contaminants of concern affecting the soil and debris are metals including arsenic, chromium, and lead; and radioactive materials including radium-226 and radon.
