Bradford Island National Priorities List Site Cascade Locks, Oregon Upland Operable Unit Engineering Evaluation and Cost Analysis Report Public Comment Period
From US Army Corps of Engineers:
Portland District, U.S. Army Corps of Engineers (USACE) invites the public to comment on the Engineering Evaluation/Cost Analysis (EE/CA) Report for the Upland Operable Unit (OU) of Bradford Island in Cascade Locks, Oregon. The EE/CA identifies and evaluates potential removal alternatives for sources of contamination within the Upland OU at the Bradford Island National Priorities List (NPL) site.
A Non-Time Critical Removal Action (NTCRA) has been determined to be appropriate at the Upland OU to address sources of contamination, including landfill waste debris, sandblast grit, spent bullet fragments, and contaminated soils that present a current and imminent threat to upland human and ecological receptors. The EE/CA has been prepared to document the removal action alternatives considered and the evaluation process for this NTCRA. The Upland OU encompasses the portion of Bradford Island east of the Bonneville Dam and contains the Landfill Area of Potential Concern (AOPC), Bulb Slope AOPC, Sandblast Area AOPC, and Pistol Range AOPC.
The EE/CA evaluated the removal action alternatives based on effectiveness, implementability, and cost criteria. The recommended removal alternatives for the Upland OU are:
Landfill AOPC: Alternative L1 - Removal of sources of contamination and contaminated soil, offsite landfilling, backfilling, slope reduction and stabilization, shoreline revetment, and site restoration.
Bulb Slope AOPC: Refurbishment and stabilization of the landfill access road along the top of the Bulb Slope AOPC as part of the Landfill AOPC Alternative L1 removal action; including excavation of associated waste debris and impacted soil.
Sandblast Area AOPC: Alternative S1 - Targeted removal of contaminated soil and spent sandblast grit, offsite landfilling, backfilling, shoreline revetment with vegetative buffer, asphalt pavement, and site restoration.
Pistol Range AOPC: Alternative P1 - Removal of contaminated soil, offsite landfilling, backfilling, and site restoration.
