FORWARD LANDFILL SAN JOAQUIN COUNTY Subsequent changes to these networks will be reflected in a Revised Monitoring & Reporting Program issued by the Executive Officer. Water Quality Protection Standard 53.A Water Quality Protection Standard (WQPS) is the analytical framework through which WMUs are individually monitored for releases and impacts to water quality (Title 27, sec. 20390, subd. (a)). Under Title 27, a WQPS is separately established for each WMU in WDRs. (Id.) 54.In accordance with Title 27, this Order, by virtue of its incorporation of Monitoring & Reporting Program R5-2023-00XX (MRP) and subsequent revisions thereto, establishes a WQPS for each WMU at the Facility. Notification of Release, Acceptance of Hazardous Waste, Recent Enforcement and Corrective Action 55.Groundwater downgradient of the old Austin Road Unit is impacted with volatile organic compounds (VOCs), including but not limited to: dichloroethane, dichloroethylene, tetrachloroethylene, and trichloroethylene. VOC impacts were detected in 1989 and, by 1991, evaluation monitoring determined that chlorinated hydrocarbon impacts extended as far as 1,000 feet downgradient of the landfill. A corrective action plan was approved for implementation in August 1991. The plan consisted of a load checking program, extraction and treatment of impacted groundwater from two wells, and continued monitoring of the effectiveness of corrective action. 56.In 1998, corrective action monitoring determined that the initial corrective actions had failed to contain groundwater contamination or remediate groundwater impacts. In April 1999, the City of Stockton (previous discharger) submitted a Draft Engineering Feasibility Study (EFS) for an improved corrective action plan. Staff determined that the Draft EFS was inadequate and requested changes. On 3 September 2000, ownership of Austin Road landfill was transferred to Forward, Inc. Forward submitted a revised EFS on 11 June 2001 and a second revised EFS on 30 August 2001. On 13 December 2001, the Central Valley Water Board issued a Time Schedule for Corrective Action. On 26 February 2002, Forward submitted an Evaluation Procedures for Proposed Corrective Action. The resulting corrective action plan includes the following activities: a.Enhance landfill gas control system to prevent further release of VOCs from the landfill; b.Continued groundwater extraction and treatment with existing extraction wells;
