Project Description - Report of Composting Site Information Tracy Material Recovery Facility and Transfer Station 30703 5 Mac4rthur Drive, Tracy, Califom/a 95377 decomposition has been achieved, the compost materials will be moved to the screening area. • At the start of all composting cycles, temperatures will be taken and recorded five days per week to confirm satisfactory results. Temperature measurements will be taken at 6 inches to 1 foot and 2 feet below the surface for the CTI SysternTm and 1.5 to 2 feet below surface for Elongated Windrow Method. This will be performed to allow for accurate temperature measurements deep within the windrow. The minimum frequency for temperature readings for all composting methods will be based on a 200 cubic yard volume per reading. Procedures for taking temperatures • Temperature probes 2 feet long, with a dial on one end and a thermocouple on the other will be used for taking temperatures. The probe will be inserted into the bag at points, which will be recorded for subsequent readings. • Depths at which the temperatures will be taken as discussed above. • The same person taking the temperatures using the same technique each time will be utilized whenever possible to aid in eliminating variables. • Points for probe insertion shall be chosen to produce the most representative readings of internal temperatures. "Clean Green Material" Production In addition to capability to compost material, the operator seeks the flexibility to produce a "clean green material" from select loads of clean green material, yard trimmings, and wood waste. The "clean green" material may be used on-site in the CTI system, or will be used as a mulch product for sale off-site. The mulch material, up to 150 TPD, could be a back- hauled in outgoing transfer trailer, thereby not contributing to the expected traffic loading. "Chipping and Grinding Operations" are described in 14CCR §17$52(x) (10) means an operation, that does not produce compost. A chipping and grinding operation may be located within a Full Solid Waste Facility Permitted facility, such as this compost facility. An overview of site operations for the "clean green material" production is presented: • "Clean green material" will only be produced from incoming loads of yard trimmings, grass clippings, and some brush. • The green material will be processed within 7 days of receipt. • "Clean green" material will not stay on-site for more than 30 days. Either the material r will be transported off-site to be sold as mulch or composted on-site. 23 Edgar&Associates,Inc. Tracy Compost Fac Projgesc042310
