DRAFT [TENTATIVE] WASTE DISCHARGE REQUIREMENTS ORDER R5-2023-00XX 25 <br />FORWARD, INC. <br />FORWARD LANDFILL <br />SAN JOAQUIN COUNTY <br />Title 27. (See Title 27 sec. 20090, subd. (f) [stating in part, “Soil Amendments – <br />Use of nonhazardous decomposable waste as a soil amendment pursuant to <br />applicable best management practices, provided that RWQCBs may issue waste <br />discharge or reclamation requirements for such use.”].) <br />87.Rinsate and residual cannery waste can be discharged to the designated LAA. <br />Excess cannery rinsate may be discharged to surface impoundments WMU F <br />West, WMU F North and future surface impoundments as long as the Discharger <br />follows an approved surface impoundment operations and maintenance plan. <br />88.Mud waste application has changed from past practices. Prior to 2017, mud <br />waste was applied to the LAA, but this practice is no longer in use. Mud waste is <br />now transported to a bermed, compacted clay pad within the landfill and is air- <br />dried. Following a drying period of a minimum of five days, the dried mud is <br />disposed in the WMUs for use as alternative daily cover. <br />89.Residuals and mud cannery waste are transported to the Facility in 10-ton <br />capacity roll-off bins. Rinsate cannery waste is transported in 5,000-gallon tanker <br />trucks and spread uniformly. Small berms were implemented to maintain dry <br />pathways for tanker trucks. Residual cannery waste is placed in a small area and <br />then spread over a larger area using a tractor blade followed by discing. The <br />dried wastes (liquid and solid) will be disked approximately 4- to 6-inches into the <br />ground. Additional tillage is used when necessary to accelerate drying and <br />minimizing nuisance conditions. <br />90.Land application of cannery waste follows a seasonal discharge and cropping <br />schedule as delineated in the 2017 Cannery Waste Land Application Area <br />Nutrient Management Plan (2017 Nutrient Management Plan) submitted by <br />Kenndy Jenks Consultants on behalf of the Discharger. Cannery waste is <br />discharged to the LAA according to the canning season, which starts in June and <br />finishes through the end of October. The LAA is then tilled, prepared for planting, <br />and seeded with a winter crop by late November. The winter crop harvest <br />typically occurs during the second half of April. No additional water besides the <br />rinsate is currently available for supplemental crop irrigation. <br />91.Excessive application of decomposable organic waste to land can create <br />objectionable odors, soil conditions that are harmful to crops, and degradation of <br />underlying groundwater with nitrogen species and certain metals, as discussed <br />below. Such groundwater degradation can be prevented or minimized through <br />implementation of BMPs which include planting crops to take up plant nutrients <br />and maximizing oxidation of biochemical oxygen demand (BOD) to prevent <br />nuisance conditions. <br />92.The Discharger is required to implement the following BMPs for cannery waste:
