The U.S. Environmental Protection Agency Region 8 (EPA) and the Wyoming Department of Environmental Quality (WDEQ) are working together to advance remediation of the former Nedlog and Williams Strategic Metals property (Nedlog Site). 

Located 2.5 miles south of Laramie, Wyoming, the Nedlog Site began operations as an alumina plant in 1943 during World War II.  The pilot plant was constructed to create a strategic resource of alumina, the base material for aluminum metal.  In the mid-1950’s, operations transitioned under the Ideal Cement Company to light aggregate production.  Aggregate production continued until the mid-1960's.

In the mid-1970’s, Nedlog Technology Group began operating the facility for secondary metal recovery.  The facility received materials, including coke, flue dust, smelter waste and waste ore, for further processing to extract metals such as mercury, indium and arsenic acid.  In 1982, Nedlog sold some assets and property to Williams Strategic Metals, Inc. which continued operations at the facility.

Since the late 1980's, the Site has undergone numerous remediation efforts.  In 1988, EPA signed a consent agreement with Williams for violations of RCRA, EPA’s hazardous waste regulations. Under the EPA consent agreement, remediation began in 1988 and continued through 2001.  The Nedlog Site later entered Wyoming’s Voluntary Remediation Program in 2011.

EPA’s Emergency Response Program plans to continue clean-up of the Site with container removal and additional assessment of the arsenic acid buildings.
