Forward, Inc. - 2 - 09 January 2024 Forward Landfill San Joaquin County The existing Forward Resource Recovery Facility (Facility) composting operation is located at 9999 South Austin Road (on APN 201-060-030) in Manteca, California. The 39.1-acre Facility is located within the 744-acre Forward Landfill in San Joaquin County. The Facility and the landfill are owned and operated by Forward Inc. The Technical Report describes depth to groundwater to be 50 to 70 feet below the groundwater surface (bgs), with seasonal variations in groundwater depth up to 10 feet. The groundwater flow velocity ranges from 0.001 to 0.003 ft/ft and generally flows in a north to northeasterly direction. The Technical Report provided annual maximum (26.67 inches), minimum (4.61 inches), and average (13.31 inches) precipitation information for the area based on data from the NOAA Stockton Airport weather station at the time of submittal. The average annual pan evaporation is 78.43 inches for the area based on data from Oakdale Woodward Dam, located approximately 13 miles southeast. The magnitude of the 25- year 24-hour design storm water is estimated to be 2.83 inches according to the NOAA Atlas 14 Point Precipitation Frequency Estimates data server. Land uses within one mile of the Facility include Forward Landfill and auxiliary properties as well as agricultural farmland. Water is supplied to the Facility by two on- site wells located on the eastern edge and southeastern corner of the Facility (Attachment A). Composting operations are prohibited within 100 feet of the wells. The closest named surface water body is the south fork of South Littlejohn’s Creek (2.5 miles northwest of the Facility). The Facility property is bermed on the north edge to minimize the potential for storm water run-on and run-off. Based on U.S. Department of Agriculture’s (USDA’s) Natural Resource Conservation Service (NRCS) soil survey soils in the vicinity of the Facility consists Clear Lake clay and Jacktone clay. The subsurface soils consist of interbedded layers of sand, silt, and lean clay. COMPOSTING OPERATIONS In 1994, composting operation began at the site. The San Joaquin County Environmental Health Department, Solid Waste Local Enforcement Agency (LEA), issued Solid Waste Facility Permit 39-AA-0020 (Permit) which authorized the Discharger to operate the composting facility. The Permit allows the composting of green materials, untreated wood waste, and food waste (non-vegetative). The Permit allows for the handling of up to 1,100 tons per day (tpd) for windrow composting. Of the 1,100 tpd of material, up to 200 tpd will be reallocated to an on-site aerated static pile (ASP) composting system. Total on-site capacity at any given time is allowed up to 156,377 cubic yards. The current allowable processing capacity is 489,859 cubic yards per year. The Facility does not utilize any additives or amendments. LEA approval is required prior to additive and amendment use as well as notification to the Central Valley Water Board.
