Document Description
The proposed project consists of operating the existing lime neutralization systems located ajacent to Pond 1 and Pond 4 to treat AMD contained in the evaporation pond system and AMD emanating from the CUD and the Delta Seep. Treated effluent that meets discharge criteria (as specified by USEPA) would be discharged to Leviathan Creek. Sludge exhibits hazardous characteristics, in which case the sludge will be disposed at an offsite Class 1 hazardous waste disposal facility. The PUD underlies the Pit and captures water that infiltrates surface soils in the Pit and conveys that water to the evaporation pond system. A surface water collection system was installed in the Pit as part of the 1985 abatement system and diverts surface runoff from the Pit to Leviathan Creek.
