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