Project Description-- Report of Composting Site Information Tracy Material Recovery Facility and Transfer Station 30703 S. MacArthur Drive, Tracy, cal/fornla 95377 , Throughput The CCOs tonnage amount will be included in the facility's permitted amounts, discussed on Page 12 and shown in Tables 2 and 3 . While the CCOs feedstock will be segregated for processing and composting, and the tonnage they represent will be recorded separately, and they will be counted as part of the total Green Material throughput under existing facility requirements. Composting Process Overview An overview of the composting process is presented below: • Incoming CCO trucks will be received and weighed at the scale located near the Site Office. The scale personnel will direct haulers to the chipping and grinding area of the composting facility. Appropriate signage will be placed within the composting facility to direct the hauler to the correct location as shown on the Site Plan. • The facility personnel will conduct a CCO load check during unloading. At least one trained load-checking employee will be present during deliveries. • The CCOs feedstock that will need to be processed at the facility will be placed into an exclusive stockpile next to the grinder, and will be ground within 24 hours of receipt. The processed CCO material will then be formed into . elongated windrows in the CCO composting area for on-site composting. • All information pertaining to each CCO windrow will be documented in site records to allow instant identification of windrow status (e.g. start date, temperature readings, turnings, and sampling) and allow site personnel to isolate material waiting testing results. The Site Manager will keep a Map in his office showing Project windrow location and numbering system. • The temperature and moisture of the windrow materials will be monitored and controlled, and the Project windrows will be turned on a regular basis so that the composting process is maintained. New materials will subsequently be added to the youngest side of the Project windrow, thus lengthening the windrow. Windrows will be turned by rolling the oldest edge of the windrow and then the next oldest material. A front-end loader and windrow turner will be used to turn the windrows. CCO windrows will be turned, wind permitting, with 5 turns within a 15-day period to ensure pathogen reduction, and then continue composting for an anticipated period of 12 to 20 weeks. Subsequent curing of material in place will take place for up to six weeks. • Water will be added as necessary to the compost windrows to maintain the appropriate composting moisture and control dust. A piped irrigation system is used to add water to the windrows, • Pathogen Reduction for Windrow Composting: The process of turning windrows provides sufficient oxygen to sustain the biological activity and keep the 35 Edgar&Associates,Inc.
