WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2014-0006 -19- <br />FORWARD INC. AND REPUBLIC SERVICES INC. <br />FORWARD CLASS II LANDFILL <br />SAN JOAQUIN COUNTY <br /> <br /> <br />assurance (CQA) plans for each new module or modules for review and approval at least <br />180 days prior to construction. <br />COMPOST FACILITY <br />77. The Composting Facility is located on 7.6 acre parcel south of the South Fork of South <br />Littlejohns Creek. The facility consists of compacted native soil pad with a minimum one- <br />percent slope to the north. The pad is protected from run-on by berms on the eastern edge <br />and a portion of the south edge of the site. The site is sloped to drain to two ditches <br />designed to contain run-off from the 25-year, 10-minute duration storm. Composting <br />windrows are constructed normal to the slope to allow free drainage and minimize ponding. <br />The surface native soils consist of lean clay to silt and silty clay. This Order requires that the <br />one-foot thick soil layer beneath composting pad areas be tested and if necessary <br />conditioned and compacted to achieve a hydraulic conductivity of 1 X 10-5 cm/sec or less. <br />78. Leachate, if any, is collected in the two ditches and drains to an unlined storm-water <br />retention basin. The Discharger does not monitor, sample or otherwise control leachate. <br />This Order requires that the retention pond be sized to contain at least a 25-year, 24-hour <br />storm event and that the retention pond be equipped with a synthetic liner. <br />79. Water collected in the retention basin will either be evaporated, used in the initial mixing of <br />the compost, used for dust control, pumped to the on-site leachate evaporation pond, or <br />transported off-site to a municipal treatment facility. <br />LAND APPLICATION OF CANNERY WASTES <br />80. Solid cannery waste will be discharged within the designated land application areas, spread <br />evenly and allowed to dry. Liquid waste (rinsate water) will be delivered in tanker trucks and <br />slowly discharged over the land application area. Small berms will be constructed to <br />maintain dry pathways for tanker trucks. The dried wastes (liquid and solid) will be disked <br />approximately 4 to 6-inches into the ground. Rapid evaporation prevents anaerobic odors <br />and interrupts the life cycle of vectors (flies). Excess cannery rinsate water may be <br />discharged to one of the Class II surface impoundments. <br />81. Excessive application of decomposable organic waste to land can create objectionable <br />odors, soil conditions that are harmful to crops and degradation of underlying groundwater <br />with nitrogen species and certain metals, as discussed below. Such groundwater <br />degradation can be prevented or minimized through implementation of best management <br />practices (BMPs) which include planting crops to take up plant nutrients and maximizing <br />oxidation of biochemical oxygen demand (BOD) to prevent nuisance conditions. <br />82. The Discharger is required to implement the following BMPs for cannery waste: <br />a. The ground surface will be prepared prior to the application of waste.
