How will storm water run-off from the solid materials handling facility be managed?
Storm water run-off will be managed on-site depending on where it falls and what it contacts. Storm water that does not fall on the solid materials handling facility will be diverted around the storage cell so it will not come into contact with stored ash and gypsum. This water will either be routed to on-site storage basins for reuse at the plant or routed to sediment ponds for removal of silt and sediment prior to release to Williamson Swamp Creek. Storm water that falls onto the storage cell (and comes into contact with stored ash and gypsum) will be collected by a sump and collection system that is integrated into the storage facility design. The water collected from the storage facility sump and collection system will be treated for removal of particulates and pH adjustment then routed to on-site storage basins for reuse at the plant. Run-off from the solid materials handling facility will not be returned to the environment without treatment.
