' Draft Environmental p Impact Report Page III-10 Forward Inc. Landfill Expansion sized based on actual leachate generation records from 1991 to 1997 and has a design capacity of approximately 3.5 million gallons. Soil treatment and sludge drying is permitted in WMU G. WMU G is divided into G-North and G-South, located north and south of the South Branch of the South Fork of Littlejohns Creek, f respectively. The WMU G units occupy the same areas as WMUs D and Future H. The WMU IJ D units have replaced WMU G-North. As currently permitted, WMU Future H will replace WMU G-South(currently the site of the materials recovery facility) to accommodate waste disposal. Forward, Inc.has not treated soils or dried sludge during the last several years. (Proposed sludge drying is discussed in Proposed Project Modifications, Solidification of High Moisture Content Wastes,below). The northern portion of Forward Landfill encompasses the former Austin Road Sanitary J Landfill, which began accepting municipal solid waste in 1954 and which, as mentioned above, 4 does not contain a base liner or LCRS. The top of the former Austin Road Sanitary Landfill has been graded to drain to the south, and a final cover was placed on a portion of the top and on the entire original northern slope. WMUs FU-03, FU-04, FU-05, and FU-06 are located within the former Austin Road Sanitary Landfill. The northern portion of WMUs FU-03 to FU-06 overlies the top of the former Austin Road Sanitary Landfill. Only Class III waste is permitted to be placed above the top of the former Austin Road Sanitary Landfill. The southern portion of these WMUs, which was constructed to meet Class II (designated waste) requirements for base liners and LCRSs, is permitted to receive designated wastes. Liners are placed to separate the Class Il waste in the southern portion of WMUs FU-03 to FU-06 from the Class III waste located in the former Austin Road Sanitary Landfill. The existing Forward Landfill facilities also include a transfer station/materials recovery facility, soil borrow areas, composting areas, and storage and support areas (see Figures III.0-Z and III.0-3). Future Permitted Waste Management Units As depicted in Figure III.0-3, future WMUs are currently permitted to the east of WMU FU-06 and in WMU Future H area(south of the South Branch), with liners and LCRSs similar to those presently used. As discussed above, WMU Future H will replace WMU G-South(currently the site of the materials recovery facility). WMU F South is currently permitted in the southwest corner of the existing Forward Landfill, south of the South Branch. WMU F South is permitted as a Class II impoundment. Permitted Waste Stream The existing Forward Landfill is currently permitted and operated as a Class II(designated waste) and Class III(nonhazardous Municipal Solid Waste)landfill. The Forward Landfill's current Solid Waste Facilities Permit(SWFP) allows a maximum inflow rate of 8,668 tons per day, or 46,080 tons per week; including some beneficial reuse materials and materials delivered to the MRF. The existing Forward Landfill may accept both nonhazardous municipal(Class III) and designated (Class II) wastes. It may also accept wastes that meet the Class II and III criteria for waste disposal as specified in the Waste Discharge Requirements (WDRs)issued by the Central Valley Regional Water Quality Control Board(CVRWQCB)for the site,wastes granted a variance to be disposed of in a Class III waste management area including,but not limited to,asbestos and automobile r. shredder waste, and a variety of nonhazardous commercial and industrial wastes including but +, U
