<br /> <br />Foothill Sanitary Landfill Page 39 of 52 San Joaquin County DPW - Solid Waste <br />Joint Technical Document Revised 01/05/2026 <br /> <br /> <br />x White goods (appliances) are diverted from the waste stream and stored onsite. The <br />landfill operator contracts with a vendor who comes onsite to remove the Freon and <br />other hazardous constituents from various appliances. Once all the hazardous <br />constituents are removed the white goods are shipped to an offsite recycling facility. <br /> <br />x Dewatered Sludge is known to accelerate decomposition at landfills and increase <br />methane production for power generation. Although the County currently does not <br />accept dewatered sludge, it may elect to do so in the future. The Foothill Landfill’s <br />Module 1 and all future Modules will be equipped with a leachate collection and <br />removal system. The County will adhere to the following sludge handling operation <br />procedures to comply with the provisions of CCR 27, Sections 20220 and 20690: <br /> <br />The County will only accept sludge from sources that have a current EPA-503 report on <br />file, demonstrating that the sludge is non-hazardous and contains at least 20 percent or more <br />solids by weight. No sludge will be accepted during wet weather. <br /> <br />The sludge will be delivered to the site at designated times to avoid peak hours and to <br />facilitate staging operations. The sludge will be deposited at designated areas within the lined <br />modules, near the active face, and outside and away from the public drop-off area. Dewatered <br />sludge will not be accepted during wet weather. <br /> <br />Foothill Landfill receives approximately 1185 tons per day of refuse (2024 average), <br />therefore no more than 200 tons of sludge will be landfilled per day, to comply with the minimum <br />5:1 ratio requirement of CCR T27. The weight of the incoming sludge will be determined at the <br />scales, and the operator will process accordingly. <br /> <br />Sludge is deposited atop solid waste at the working face of the landfill and mixed as <br />thoroughly as possible with the solid waste. The mixture is then spread, compacted, and <br />covered in the usual manner. <br />
