Document Description
DTSC is considering approval of a Post-Closure Permit Application for three former surface impoundments. These surface impoundments were used for the storage of hazardous wastes at the facility and were closed in 1986. DTSC approved the closure certification report in 1991. All wastes from these impoundments were removed and disposed properly. Soils above the groundwater table were removed and replaced with clean fill. However, groundwater impacts still remain as a result of the operation of these units and therefore a Post-Closure Permit is required. The Permit will require the facility to continue to pump and treat the contaminated groundwater, monitor the groundwater, and to inspect and maintain the equipment used for these activities. A deed restriction is currently in place prohibiting the use of groundwater for agricultural purposes or human consumption. The deed restriction shall remain in place until standards set by the Regional Water Quality Control Board for drinking water have been achieved.
