DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-00XX 10 <br />FORWARD, INC. <br />FORWARD LANDFILL <br />SAN JOAQUIN COUNTY <br />19.The Discharger proposes to continue discharging asbestos-containing waste <br />(i.e., >1% asbestos) at the Facility. Although asbestos-containing waste is <br />classified as “hazardous” under California Code of Regulations, title 22 (Title 22), <br />the discharge of such waste does not pose a threat to water quality and is <br />therefore authorized for WMUs as specified in Section B.1 and Table 16. <br />(Health & Saf. Code, sec. 25143.7.) <br />20.The Discharger proposes to continue discharging Treated Wood Waste, as <br />defined per Title 22 section 67386.4, at the Facility. Treated Wood Waste may <br />contain chemicals such as chromated copper arsenate (CCA), <br />pentachlorophenol, creosote, acid copper chromate (ACC), ammoniacal copper <br />arsenate (ACA), ammoniacal copper zinc arsenate (ACZA), or chromated zinc <br />chloride (CZC). In accordance with Title 22 section 67386.11, this Order <br />authorizes the discharge of treated wood waste to composite-lined WMUs <br />specified in Section B.1 and Table 16, provided that the Discharger complies <br />with Article 11.2 of the Health and Safety Code commencing with section 25230; <br />Title 22 section 67386.3; and the applicable SPRRs. <br />21.The Discharger proposes to continue discharging certain Designated Wastes <br />(per Wat. Code, sec. 13173)—specifically industrial waste, coal and wood ash, <br />contaminated soils, salty wastes, and auto shredder waste—to Class II WMUs at <br />the Facility. This Order authorizes the discharge of such wastes to the WMUs <br />specified in Section B.1 and Table 16. <br />22.DTSC has granted a variance from Title 22 hazardous waste management <br />requirements for disposal of shredder waste (see State Water Board Resolution <br />No. 87-22). Shredder waste is any non-recyclable wastes which results from the <br />shredding of automobile bodies (from which batteries, mufflers, and exhaust <br />pipes have been removed), household appliances, and sheet metal. The <br />Discharger proposes to discharge shredder waste to units with single composite <br />liners. <br />23.The Discharger proposes to discharge cannery rinsate muds, dewatered <br />sewage, and water treatment sludges to units with single composite liners. If <br />disposed directly into the landfill, sludge is mixed with refuse so that the mixed <br />sludge will not exceed the moisture holding capacity of the refuse. Rinsate muds <br />and sludges containing excess moisture may be air-dried on a bermed, <br />compacted clay pad. When dry, the rinsate mud, sludge, and underlying soil <br />impacted by contact with the sludge are disposed in the WMU. <br />24.The Discharger accepts soils contaminated with less than hazardous levels of <br />petroleum hydrocarbons. These soils were historically either treated in a land <br />treatment unit or discharged to Class II landfill units. The Discharger <br />demonstrated that soil contaminated with less than hazardous levels of
