Salmon Creek Sandblast Waste Abatement Remedial Action Plan

Salmon Creek Sandblast Waste Abatement Remedial Action Plan

The proposed Work Plan for the remediation of lead-impacted shallow soil within the State right-of-way (ROW) under the Salmon Creek Bridge to statistically-based concentrations below the regulatory commercial/industrial land use cleanup goal. Remedial excavations on private parcels east of the State ROW would be performed to reduce lead concentrations below the regulatory residential land use cleanup goal (80 mg/kg plus background concentration). Removal of vegetation would be necessary prior to removal of lead-impacted shallow soils; however, the targeted removal would preserve vegetation on steep, difficult to access slopes. Excavation depths would vary from 0.5 feet to 1.5 feet. In situ testing and screening during excavation would be used to verify soils left in place meet the cleanup goals. Excavated materials would be shuttled to an onsite staging area and temporarily stockpiled. Areas where lead-impacted soils are removed would be restored by placement and contouring of imported borrow material, amendment of soils as needed, erosion control, revegetation, and wetland restoration.
