EPA's National Priorities List dated July 22, 1989 and <br /> the State of California Clean-up and Abatement Order No. <br /> 87-026 dated January 23, 1987. Currently, this water is <br /> being discharged to the French Camp Slough. The <br /> Trichloroethene content after air stripping is <br /> nondetectable. The produced Arsenic is found to be <br /> naturally occuring in the local ground water. The water <br /> quality is monitored in accordance with the NPDES permit <br /> to ensure compliance with the EPA's drinking water stan- <br /> dards. The Sharpe Army Depot has entered into a <br /> utilities service contract with San Joaquin CoGen Limited <br /> to provide treated effluent from their remediation <br /> facility. <br /> Wastewater Discharge <br /> San Joaquin CoGen Limited considered four options for the <br /> disposal of the wastewater: disposal into the San Joa- <br /> quin River, zero discharge using evaporative technology, <br /> municipal sewage systems for disposal, and a Class I <br /> non-hazardous waste injection well . <br /> The Facility reviewed the option of discharging its <br /> wastestream to the San Joaquin River with the California <br /> Regional Water Quality Control Board. The Facility's <br /> waste stream will contain 7, 000 to 10, 000 ppm TDS (Total <br /> Dissolved Solids) . New discharges to the river are <br /> limited to 500 ppm TDS. The costs of treatment and <br /> piping to the river were sufficient cause for this option <br /> to be rejected. <br /> The Facility considered the use of evaporative technology <br /> to create a "zero liquid discharge" facility. The cost <br /> of the energy consumed to evaporate the water and the <br /> cost of the technology was prohibitive. The resultant <br /> saltcake would not have been suitable for disposal in <br /> local municipal waste facilities. <br /> The Facility's waste stream was unacceptable to the local <br /> municipal sewage system because of outfall limitations on <br /> the system's operating capacity. <br /> The Facility determined that use of an injection well was <br /> the most feasible means for disposal of its wastewater. <br /> e. Special Conditions <br /> The Code of Federal Regulations (CFR) requires that a <br /> permit for a Class I well be effective for a fixed term <br /> not to exceed ten years from the effective date of the <br /> permit. This permit will be effective for a 10-year <br /> period should the permit be issued as drafted (40 CFR <br /> 3 <br />
