EPA v. U.S. Dept. of the Navy, Naval Weapons Station

Case summary

The purposes of this agreement are identify remedial alternatives for Operable Units which are appropriate at the Site prior to the implementation of final remedial action(s) for the Site, and to establish requirements for the performance of the RI to determine fully the nature and extent of the threat to the public health or welfare of the environment. The ROD for OU-7 was signed on August 14, 2007. OU-7 is the tetrachloroethene (PCE) portion of the Site 26 groundwater solvent plume southwest of Building GB-1. The remedy relies on the current OU-3 remediation system (air sparging with soil vapor extraction (AS/SVE), long-term monitoring and land use controls). The AS/SVE system began operation in 2001 to treat the volatile organic contaminant plume (primarily TCE) associated with the Site 26 groundwater plume. Under OU-7 there are no capital costs. Marginal costs for additional monitoring wells to omonitor state of the OU-3 and OU-7 plumes are minor and can be applied to the approved OU-3 remediation project underway for Site 26. Additionally, costs for preparing the proposed CEA under alternative 3 are already budgeted under the OU-3 remediation project. ROD signed September 18, 2014. Site 9 and 41. Explanation of Significant Differences signed September 24, 2019. EPA Operable Unit 4, Sites 20, 23 & 27. No Further Action issued on March 14, 2021 for Site 41 ?
