Demonstration of the Terra Therm In-Situ Destruction (ISTD) Technology
This project involves an evaluation of the ISTD system which was developed by TerraTherm, Inc. (TerraTherm). The evaluation site is a former hexachlorocyclopentadiene disposal pit (the Hex Pit) located at the Rocky Mountain Arsenal (RMA) in Commerce City, Colorado. The technology evaluation was conducted by the EPA SITE program in cooperation with the U.S. EPA Region 8, the Colorado Department of Public Health and Environment (CDPHE), and RMA's Remediation Venture Office (RVO) (U.S. Army, Shell Oil Company, and U.S. Fish and Wildlife Service). The operation of the (ISTD) system was terminated soon after initial startup and before the SITE demonstration could be completed, due to the destruction of system components from highly corrosive vapors and liquids. Consequently, the final report focuses primarily on site characteristics unique to the Hex Pit and the ISTD system design, a description of the demonstration methodolgy and results including a chronology of activities and events that occurred during operation of the ISTD system, and a description of the component destruction and what conditions of the ISTD system, and a description of the component destruction and what conditions may have lead to the destruction.
