Corrective Action Financial Assurance Estimate <br />Foothill Sanitary Landfill <br />San Joaquin County <br />August 9, 2006 <br />1.1 Purpose <br />A corrective action financial assurance for a "reasonably foreseeable release" from a <br />landfill is required under Sections 20380(b) and 22220-22222 of Title 27, California <br />Code of Regulations. In order to satisfy this corrective action financial assurance <br />requirement, the Discharger must estimate the cost of the corrective action taken to <br />mitigate a "reasonably foreseeable release". This report documents the rationale, <br />assumptions and results used in preparing the estimate. The approach used in developing <br />the estimate is summarized below. <br />1. Assess the physical layout, geology, containment systems, environmental <br />monitoring systems, and history of impacts to either groundwater or surface <br />water. <br />2. Develop a hypothetical release scenario based on the data collection in Item 1. <br />3. Developed a hypothetical corrective action response to mitigate the impacts <br />envisioned under the hypothetical release scenario. The extent and complexity of <br />the corrective action response is proportional to the environment threat of the <br />release and is consistent with the types and magnitude of corrective action <br />commonly mandated by the Regional Water Quality Board at the time this <br />document was prepared. <br />4. Costs are estimated for implementation of the corrective action based on the <br />premise that the corrective action response will be designed and constructed by a <br />third party. Costs presented in the estimate are typical for engineering and <br />construction services rendered in the Northern Central Valley in 2006. <br />1.2 Site Description <br />The Foothill Sanitary Landfill, located at 6484 N. Waverly Road in eastern San Joaquin <br />County. The landfill is located on an 800 -acre parcel and is owned by San Joaquin <br />County. The landfill is a single Class III Waste Management Unit comprised of Module <br />1, and Module 1. Waste discharge includes commercial and household waste, <br />construction/demolition waste, and agricultural waste. The total capacity is <br />approximately 102 million cubic yards. Final closure of the facility is projected to occur <br />in 2058. <br />73467 1 August 9, 2006 <br />LA 31109 Corrective Action Financial Assurance Cost Estimate <br />Foothill Sanitary Landfill <br />
