3-9 Forward Composting Facility SWT Engineering Report of Composting Site Information - August 2019January 2022 z:\projects\allied waste\forward\resource recovery facility\5 yr permit rvw 2019-2020\rcsi 2019\text\sec 3.doc pumped at a rate of approximately 1 ,500 gpm at a maximum frequency of approximately 27 times in a typical work day. Another well is locat ed south of the South Fork of South Littlejohn’s Creek , in the southeast corner of the RRF/Compost Facility area, and has a capacity of 500 gpm. The third well is located along the northern boundary of the former Austin Road Landfill. This well was insta lled in 1972 and has a production of approximately 60 gpm. The fact that groundwater flow near the existing Forward Landfill is not modified by pumping from this well suggests that it is screened in a confined unit below the uppermost groundwater units that are monitored at the site. The fourth production well is located along the eastern boundary of the site, just south of the entrance to the RRF/Compost Facility. The locations of the wells located in the RRF/Compost Facility area is shown on Figure 2. Water uses include site construction and waste disposal operations, RRF /Compost Facility operations, dust control, equipment maintenance operations, sanitary facilities, firefighting, and emergency situations. c. Preprocessing Procedures Preprocessing will include inspecting the incoming material to remove any visible contaminants. Loads will be visually inspected in the material sorting area at the Compost Facility (see Figure 2). A magnetic separator is used to extract nails and other ferrous contaminants from the green waste material after it has been shredded. d. Process Time As discussed in Section 1.3.1, the Compost F acility is designed and permitted to process up to 1,100 tpd of waste.compostable materials. The specific capacity depends on t he composting process being used, density of materials, and the quality of compost product. The active windrow compost process time is between approximately 4 to 12 weeks, depending on the compost product quality. The windrow curing process takes from approximately 1 to 6 months. The ASP composting process time is approximately 8 weeks. e. Chemical or Bulking Agents As previously mentioned, amendments and/or additives are not currently utilized at the RRF/Composting facility. In addition, any oversize d screened materials are landfilled.Prior to use of amendment and/or additives, Forward will obtain approval from the LEA and Regional Water Quality Control Board. 3.5.3 Climatic Conditions Climatic conditions are not expected to adversely affect site operations. It does not snow but can occasionally freeze at the site. Forward implements a winterization program each year to prepare the internal roads for all weather access during the rainy season (October through April). The climate of the region is typical of the California Central Valley. Winters are generally cold and wet with fog, while summers are hot and dry. Climatological data used in the site design was gathered from representative weather stations near the site. Representative climatologic stations were selected based on their proximity to the site and a reliable period of records for the station. Temperature. Summer high temperatures often exceed 100 °F, averaging from the low 90’s in the northern part of the valley to the high 90’s in the south. The daily summer
