3.3 FEEDSTOCK CHARACTERISTICS AND QUALITY The feedstock materials may include green material, food processing residue, food waste, garbage, biosolids, and mixed solid waste, as described in 14 CCR, Section 17852. Incoming materials are checked for physical contaminants. The load inspection process begins at the RRF. All loads, except for special handling wastes such as wood wastes and wastes not needing any preprocessing, are brought to the RRF and separated. The loads are spread out in the sorting building and the entire load is checked for recoverable materials, compostable materials, landfill materials, and unacceptable waste. Loads of material that have been processed prior to arriving at the Compost Facility will be visually inspected to ensure that contaminants are removed. Feedstock such as food processing residue will be incorporated immediately into compost piles to minimize the chance of vector attraction and reproduction and odor production. Semi-solid and liquid feedstocks will be added to other feedstocks at a rate to meet the composting mixture moisture criteria, thus minimizing the potential for leachate formation. Semi-solid and liquid feedstocks will be incorporated immediately into compost piles to minimize the chance of vector attraction and reproduction and odor production. Other highly putresible wastes such as grass will also be incorporated immediately into compost to minimize the chance of vector attraction and reproduction and odor production. All feedstocks will be mixed in proportions that promote efficient composting, aerobic conditions and minimize ammonia odor release. 3.4 AIRBORNE EMISSION CONTROLS In order to reduce airborne emissions, dust is controlled at the site by (1) proper maintenance of haul roads (paving, grading, oiling, and watering), (2) limiting the speed of all vehicles on site to 10 miles per hour, and (3) proper moisture content of compost piles. Water is the main dust control procedure used to control dust. Surface water runoff or on-site well water will be applied to the main access road and processing areas to control dust. No disposal or treatment of this water is required since only a minimal amount is utilized and either evaporates or is absorbed by the road or ground resulting in no run-off.
