The work required under this Agreed Order (AO) is to address remaining gasoline-related contamination in soil and groundwater at 1808 N 1st Street. A release of gasoline from an underground storage tank (UST) system was first identified in 1982. Since that time, various investigations and remedial actions have taken place including pumping to remove free product in 1982 and 1983. An assessment of the extent of groundwater contamination was performed by the U.S. Geological Survey (U.S.G.S.) in 1991. The USTs were removed in 2005. The extent of soil and groundwater contamination was reassessed in 2017. The 2017 study showed that while soil and groundwater contamination concentrations remain above MTCA Method A cleanup levels, the extent of contamination is much smaller than the extent of contamination delineated in 1991.
The property is under a Lease-to-Own agreement between the City and a Lessee. The work described herein will be done on behalf of the City, but will need to be done in consultation with the Lessee. This includes coordinating locations and periods of work with the Lessee to minimize adverse impacts to the Lessee’s operations. Cleanup at the site under this Agreed Order is proposed as an Interim Action. An Interim Action is a cleanup action under the Model Toxics Control Act (MTCA) that can be performed at any time, and potentially result in a final cleanup action. A Remedial Action Grant for this project has been received by the City of Yakima to cover the clean-up costs of this project. (1808 North 1st Street, site 4922 – TCPRA-1921-Yakicm-00121 for $1,215,000 state share). |
