Report of Composting Site Information Tracy Material Recovery Facility and Transfer Station 30703 S. MacAurthur Drive, Tracy, Ca. 95377 content of feedstock materials. A water truck may also be used to control dust generation during grinding or screening and be available for fire protection. • During the pathogen reduction phase, the controlled aeration process in the covered ASP method provides sufficient oxygen to sustain the biological activity and keep the material at a temperature of 55 degrees Celsius (131 degrees Fahrenheit), or higher, for a period of 3 days, or longer, which meets regulatory pathogen reduction requirements (14 CCR §17868.3). There will be a minimum of 2 rotations of the ASP during a 45-day period during which readings such as temperature and oxygen content are monitored and documented on a continual basis. For management purposes, upon completion of the pathogen reduction phase, temperature of the windrows is measured automatically and aeration flow rates are adjusted by the control system as needed to properly manage the composting process, minimize fire danger, and produce optimum end product. When the desired level of decomposition has been achieved, the compost materials will be screened, then moved to the curing areas for a two to six-week period or left in place until shipment from the site. • Compost product will be sampled at a frequency of one composite of twelve samples per each 5,000 cubic yards for the metals constituents required by 14 CCR §17868.2. • From the start of all composting cycles, temperatures will be taken and recorded automatically, and monitored daily to confirm satisfactory results. Temperature qP measurements will be taken at 12 to 18 inches below surface for the ASP process. The minimum frequency for temperature readings for this method will be based on a 200 cubic yard volume per reading. Procedures for taking temperatures • Temperature probes 1 to 2 feet long, with a dial on one end and a thermocouple on the other will be used for taking temperatures. The temperature probes will transmit readings to the control system via hard-wire or radio frequency connections. • Depths at which the temperatures will be taken as discussed above. • Personnel monitoring the temperatures will be trained in proper placement of probes and standard operating procedures, which will be utilized whenever possible to aid in eliminating variables. • Points for probe insertion are constructed into the cover and are designed to produce the most representative readings of internal temperatures. Extended Aerated Static Pile An extended aerated static pile is operated essentially in the same way as the elongated aerated static pile. However, new feedstock is placed alongside and up against the previously placed material. The turning cycle and time for compost completion is essentially the same as for the elongated aerated static pile. The identity 16
