The area to be excavated is immediately adjacent to the former Diamond Alkali Plant and the material at depth contains concentrations of up to the parts per million range of 2,3,7,8-TCDD. The removal will be conducted in two phases: phase 1 will result in the excavation of 40,000 cubic yards of material and its transport off-site for disposal and phase 2 will result in the removal of 160,000 cubic yards of material and its transport and disposal in a confined disposal facility. The parties will reimburse EPA for oversight.
