OU 01 Alternatives 4 and 5 (Landfill Capping with a Part 360 Cap – Existing or Extended Landfill Footprint), 6 (Landfill Capping with a Clean Soil Cover - Extended Landfill Footprint), 7 (Partial Removal and Off-Site Disposal with In-Situ Stabilization) and 8 (Partial Removal, Ex-Situ Stabilization and On-Site Placement with In-Situ Stabilization) also satisfy this criterion, with the waste capped under Alternatives 4, 5 and 6, or stabilized under Alternatives 7 and 8.
The long-term effectiveness of Alternative 6 (Landfill Capping with a Clean Soil Cover - Extended Landfill Footprint) is uncertain as leaching of lead from the ash waste could occur through the infiltration of precipitation and snow melt into the waste.
OU 01 Alternatives 4 and 5 (Landfill Capping with a Part 360 Cap – Existing or Extended Landfill Footprint), 6 (Landfill Capping with a Clean Soil Cover - Extended Landfill Footprint), 7 (Partial Removal and Off-Site Disposal with In-Situ Stabilization) and 8 (Partial Removal, Ex-Situ Stabilization and On-Site Placement with In-SituStabilization) also satisfy this criterion, although ash waste remains at OU 01 under these alternatives.
OU 01 Alternative 6 (Landfill Capping with a Clean Soil Cover - Extended Landfill Footprint) has the lowest cost, followed by Alternative 5 (Landfill Capping with a Part 360 Cap – Extended Landfill Footprint).
