Remediation
CERCLA Five-Year Reviews, Salton Sea Test Base, Imperial County, CA.
TREVET performed five-year reviews evaluating risk management actions associated with explosive safety risks of unexploded ordnance. Close coordination with Federal and state regulators as well as community stakeholders was an essential part of the process. Project plans included a component for munitions and explosives contaminants avoidance, an Environmental Protection Plan for biological and cultural resource avoidance, and a Construction Quality Control Plan for re-installation of warning signs required by the remedy. Shoreline walkover surveys were conducted by TREVET project staff, a UXO technician, biologist, archeologist, and a Tribal monitor to verify that conditions were as reported in the Navy’s decision document. Findings identified that the warning sign requirements of the remedy were not being met, and that Aeolian processes and evaporation are contributing to continuing recession of the Salton Sea, causing increasing exposure of the shoreline.
“The quality of the field work and associated reporting was very good… The reports were approved with minimal internal and external comments, hence the ahead of schedule completion of the project.”
