1-1 Forward Composting Facility SWT Engineering Report of Composting Site Information - August 201 9January 2022 z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2019-2020\rcsi 2019\text\sec 1.doc This Report of Composting Site Information (RCSI) was prepared to comply with the California Code of Regulations, Title 14 (14 CCR), Section 17863 for compost operations. 1.0 FACILITY OVERVIEW 1.1 Introduction This RCSI describes the design and operation of the Forward, Inc. (Forward) Compost Facility (Compost Facility). The Forward site is an existing solid waste disposal and resource recovery facility (RRF) located at 9999 South Austin Road, Manteca, California (see Figure 1). The site is wholly-owned and operated by Forward. The landfill was permitted and opened in 1973. The RRF began operations in 1975. The Forward RRF building is located in the south east ern portion of the site, and is operated in compliance with SWFP No. 39 -AA- 0020 (see Appendix A). The compost facility is located in the same area as the RRF (southeastern portion of the overall property) adjacent to the RRF building (to the north, south, and west), as shown on the Site Plan (Figure 2). The Compost Facility is also included under SWFP No. 39-AA-0020 and began operation in 1994. The Forward RRF /Composting Facility serves the San Joaquin County cities of Stockton, Lathrop, Manteca, as well as jurisdictions in Sacramento County (the cities of Citrus Heights, Elk Grove, and Rancho Cordova) and Stanislaus County (the cities of Oakdale, Hughson, and Waterford). Access to the site is from Austin Road, with the entrance along the eastern site boundary, south of the Forward Landfill main entrance and the South Fork of South Littlejohn’s Creek. An intermittent creek, the South Fork of South Littlejohn’s Creek (South Fork), crosses the site in a southwesterly direction. The creek is a tributary to South Littlejohn’s Creek, itself a tributary to French Camp Slough, which ultimately dischar ges into the San Joaquin River. Surface water runoff from the northern portion of the site that has not contacted any waste is collected in on-site storm water drainage basins, from which it may be ofdischarged to South Littlejohn’s Creek (either North or South f Fork depending on which side the precipitation falls). All runoff from the northern portion of the site north of the South Fork that has contacted waste is collected and pumped into one of two leachate evaporation ponds located on site. The entire RRF and separation area is bermed on the north, south and northeast sides and graded for screening purposes and to segregate non-contact storm water from the RRF operations. All runoff from the RRF/Composting Facility runs along the north and south perimeter ditches to the sedimentation basin in the southwest area of the RRF/Composting Facility site. WDR Order No. R5 -2014-0006 and WDR Order No. 2020 - 0012-DWQ requires that the sedimentation basin is sized to contain at least a 25 -year, 24- hour storm event and be equipped with a synthetic liner. Based on past storm eventsstormwater design calculations in Appendix C , the basin is adequately sized. Water collected in the basin will either be evaporated, used in the initial mixing of the compost, used for dust control, pumped to the on-site leachate evaporation pond, or transported off - site to a municipal treatment facility. Forward operates a C omposting Facility in the south east ern portion of the site for the non- recyclable organic wastes received at the RRF. Material received at the RRF for composting may include, but not be limited to, green material, green material mixed with food waste, food waste, food processing residue, manure, mixed paper, cannery rinse water, and agricultural waste. Additional information about the types of material accepted is included in Section 1.3. The facility utilizes both traditional windrow composting and an aerated static
