<br /> <br />Foothill Sanitary Landfill Page 6 of 52 San Joaquin County DPW - Solid Waste <br />Joint Technical Document Revised 01/05/2026 <br /> <br /> <br />CCR Title 27 Section 20220 (c) regarding dewatered sludge states: <br />(c) Dewatered Sludge—Dewatered sewage or water treatment sludge may be <br />discharged at a Class III landfill under the following conditions, unless DTSC determines that <br />the waste must be managed as hazardous waste: <br />(1) the landfill is equipped with a leachate collection and removal system (LCRS); <br />(2) the sludge contains at least 20 percent solids (by weight) if primary sludge, or at least <br />15 percent solids if secondary sludge, mixtures of primary and secondary sludge, or water <br />treatment sludge; and <br />(3) a minimum solids-to-liquid ratio of 5:1 by weight shall be maintained to ensure that <br />the co-disposal will not exceed the initial moisture holding capacity of the nonhazardous solid <br />waste. The actual ratio required by the RWQCB shall be based on site specific conditions. <br /> <br />The County will adhere to sludge handling operation procedures (Section 6.4.4) to <br />comply with the provisions of §20220. <br /> <br />3.2. Waste Quantities <br /> Foothill Sanitary Landfill is currently permitted to receive a <br />maximum of 1,500 tons per day 7 days per week. Beginning January 10th 2026, <br />normal operating hours will be revised to Monday-Friday, 7:00 am – 5:00 pm. <br />Waste will only be accepted from contracted commercial haulers. All other <br />haulers will be directed to other permitted facilities. The operator will notify the <br />LEA two weeks in advance of any planned Saturday operations. <br /> <br />The annual waste quantities received at Foothill Landfill have increased approximately <br />107% since 2014 (Table 2). This is more than the 3% annual average previously projected. <br />However, current county plans call for a significant reduction in waste quantities in the <br />immediate future.
