This document is the Standard Operating Procedure SOP for the performance of a survey of underground storage tanks UST and other subsurface structures at the Umatilla Depot Activity UMDA, Hermiston, Oregon This plan has been prepared under Contract No. DAAAl5-88-D-0008, Delivery Order No. 3, for the U.S. Army Toxic and Hazardous Materials Agency USATHAMA in support of the U.S. Department of Defense DOD Base Realignment and Closure BRAC Program at UMDA. This project is being performed in conjunction with, though not as part of, the Remedial InvestigationFeasibility Study RIFS of UMDA. The Army needs to determine--prior to base closure and property excessing--if any USTs are leaking or have leaked, thereby releasing contaminants to surrounding soils and possibly groundwater, and if other subsurface structures exist that may be potential contamination sources or potentially providing conduits for contaminant migration. This SOP presents the technical approach for performance of the USTsubsurface structure survey at UMD. It includes the methodologies and procedures that will be followed in identifying and locating USTs and other subsurface structures, performing leak testing of the tanks, and performing sampling investigations, as necessary.
