DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-OOXX 19 <br /> FORWARD, INC. <br /> FORWARD LANDFILL <br /> SAN JOAQUIN COUNTY <br /> Monitoring Location Program Status <br /> Point <br /> ASW-1 North Fork Littlejohns Background Operational <br /> Creek (Upstream) <br /> ASW-2 North Fork Littlejohns Discharge Operational <br /> Creek (Downstream) <br /> See Glossary for definitions of terms and abbreviations in table. <br /> 53. As of the adoption of this Order, the above-described networks comply with the <br /> monitoring requirements of Title 27 (see Title 27, sections 20415-20435). <br /> Subsequent changes to these networks will be reflected in a Revised Monitoring <br /> & Reporting Program issued by the Executive Officer. <br /> Water Quality Protection Standard <br /> 54. A Water Quality Protection Standard (WQPS) is the analytical framework through <br /> which WMUs are individually monitored for releases and impacts to water quality <br /> (Title 27, section 20390 subdiv. (a)). Under Title 27, a WQPS is separately <br /> established for each WMU in WDRs. (Id.) <br /> 55. In accordance with Title 27, this Order, by virtue of its incorporation of <br /> Monitoring & Reporting Program R5-2023-OOXX (MRP) and subsequent <br /> revisions thereto, establishes a WQPS for each WMU at the Facility. <br /> Notification of Release, Acceptance of Hazardous Waste, Recent Enforcement <br /> and Corrective Action <br /> 56. Groundwater down-gradient of the old Austin Road Unit is impacted with VOCs, <br /> including but not limited to: dichloroethane, dichloroethylene, tetrachloroethylene, <br /> and trichloroethylene. VOC impacts were detected in 1989 and by 1991 <br /> evaluation monitoring determined that chlorinated hydrocarbon impacts extended <br /> as far as 1,000 feet down-gradient of the landfill. A corrective action plan was <br /> approved for implementation in August 1991. The plan consisted of a load <br /> checking program; extraction and treatment of impacted groundwater from two <br /> wells; and continued monitoring of the effectiveness of corrective action. As <br /> noted in CAO R5-2017-0703, the 1991 corrective action plan was insufficient to <br /> remediate the groundwater impacts since VOCs were still detected in <br /> downgradient monitoring wells. <br /> 57. In 1998, corrective action monitoring determined that the initial corrective actions <br /> had failed to contain groundwater contamination or remediate groundwater <br /> impacts. In April 1999, the City of Stockton (previous discharger) submitted a <br />
