Big B Mini Mart Remedial Action Completion Report
Ecology is providing an opportunity for the public to review and comment on the "Remedial Action Completion Report, Big B Mini Mart Site" dated November 2022 for the Big B Mini Mart site, located at 1611 Canyon Road in Ellensburg. This report documents the completion of one portion of the combined remedy for the site during the period from 2021 to 2022. This is not the final cleanup action since other cleanup action components will be implemented under the Cleanup Action Plan (CAP).
From 2021 to 2022, the following cleanup actions were performed:
Excavation of contaminated soil (as shown in Figure 2.1 of the Remedial Action Completion Report)
On-site landfarming of excavated soil
Transportation and proper disposal of some petroleum-contaminated soil at a permitted landfill
Installation of monitoring wells and groundwater monitoring
Sub-slab vapor assessment at the station building
All fields are optional unless otherwise indicated.
