Problems/Comments

The Donnelly Training Area (DTA) Rifle Range Military Munitions Response Program (MMRP) site is a closed range managed by Fort Wainwright and consists of 14.26 acres located 107 miles southeast of Fairbanks, Alaska, and west of Fort Greely in an area known as the "keyhole", on property owned by the Bureau of Land Management (BLM). The DTA Rifle Range was used from approximately 1950 to 1956. In 1995, custody of the property was realigned from Fort Greely to Fort Wainwright. A remedial investigation (RI) was conducted in 2010. The RI included an instrument aided visual survey (a Schonstedt magnetometer) to assist in identification of munitions explosive constituents (MEC) and munitions debris (MD) on the surface and subsurface. No MEC and MD was identified. As part of the 2010 RI 15 analytical soil samples were collected from 6-12 inches below ground surface (bgs) and analyzed for total metals, mercury and explosives. Samples were collected from the firing line, sounds, and backstop berms at the DTA Rifle Range. All analytical sample results collected during the 2010 RI were below DEC cleanup levels. Metals were detected, but were within background concentrations for the site. The RI recommended the site go to a No Further Action status under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and State of Alaska Contaminated Site regulations in 18 AAC 75. Based on the results from the previous investigations, DEC concurred with the recommendation for the DTA Rifle Range to go into a No Further Action status. Currently the land at the DTA Rifle Range is undeveloped, and the anticipated future land use is expected to remain the same as the current land use. The corresponding U.S. Army HQAES site number is: 02871.1089.
