Atlas "D" missile site operated by the Air Force as part of the 564th Strategic Missile Squadron at F.E. Warren Air Force Base, Wyoming.

Location and Description: The property was one of three Atlas "D" missile sites operated by the Air Force as part of the 565th Strategic Missile Squadron at F.E. Warren Air Force Base, Wyoming. The property is located approximately 20 miles southeast of Cheyenne and consisted of 746 acres acquired by purchase and condemnation between 1959 and 1961. 

The property was excessed to the General Services Administration in 1965. The 330 fee acres and easements over 11 acres were sold to Southern Scrap Iron and Metal Company, St. Louis, Missouri. This property is currently owned by Mr. Craig Johnson of Cheyenne, Wyoming. The remaining easements over 404 acres were conveyed to Mr. Floyd Miller and others. 

Problem and Response: Due to trichloroethene (TCE) groundwater contamination, a Hazardous, Toxic and Radioactive Waste project has been initiated for this site under the Defense Environmental Restoration Program for FUDS. 

Remedial Action: A remedial action contract was awarded in 2011 with FUDS funding to begin a performance-based contract action. The contract includes a five-year basic award to get to remedy in place. An option to the contract was awarded in 2012 to address remediation over the entire area of the plume of contaminated groundwater that will extend the contract until 2017. A contract action is planned to extend operation and monitoring for another five-year period to reach response complete. 

Activities for 2015: The U.S. Army Corps of Engineers' contractor has completed characterization work and a pilot study to support the remedy selection. The proposed plan and decision document are to be completed this year, followed by completion of the remedial design and implementation of the full scale remedy. The USACE contractor will conduct public involvement efforts to include public review and comment of the Proposed Plan and a public meeting if requested to make the community aware of activities planned. 

Proposed Activities for 2016: Under the remedial action contract, the USACE contractor will continue performance monitoring to track reduction of the TCE contamination of the remedy in place. 

Issues and Other Information: The biggest challenge will be to satisfy WDEQ and EPA concerns regarding the reduction of TCE contamination in the groundwater plume.
