Superfund Record of Decision (EPA Region 8): Rocky Mountain Arsenal (Operable Unit 26), CO. (Tenth remedial action), September 1991

Technical Report · Thu Sep 05 04:00:00 EDT 1991

OSTI ID:7029269

The Rocky Mountain Arsenal (RMA) (Operable Unit 26) site comprises part of the 17,000-acre RMA site, which is a former U.S. Army chemical warfare and incendiary munitions manufacturing and assembly plant in Adams County, Colorado. Since 1970, U.S. Army facility operations primarily have involved the destruction of chemical warfare materials. Because final remediation of the RMA site will take many years to complete, 13 interim response actions (IRAs) were determined necessary prior to implementing the final On-Post Record of Decision (ROD). Operable Unit 26 (OU26), which is one of these 13 IRAs, is composed of the piping and equipment in the buildings in the North and South Plants at RMA. The ROD addresses contaminated piping and equipment in numerous buildings in the North and South Plants, and contaminated 1-ton containers. The primary contaminants of concern affecting the debris and air are the chemical agents GB (Agent GB, Sarin), HD (Agent Mustard), L (Agent Lewisite), and VX (Agent VX). The selected remedial action for the site is included.
