Project Description— Report of Composting Site Information <br /> Tracy Material Recovery facility and Transfer Station <br /> 30703 5. MacArthur Drive, Tracy, califomia 95377 <br /> d. A description of the proposed methods used to control litter, odors dust <br /> f rodents, and insects. ' <br /> i <br /> Litter Control: The litter from the composting operation is not expected to be <br /> significant. The contamination found in green material is typically inert debris from the <br /> yard. Vehicles hauling green materials to the facility will be required to be covered if the <br /> loads are susceptible to loss of branches or other green material on the roadways off- <br /> site and on-site. Materials dropped on on-site roads will be routinely picked-up. The litter <br /> will be policed and removed from the facility's perimeter at least weekly or more <br /> frequent if necessary. Site personnel and facility users will be directed to use litter <br /> containers that will be provided for trash. Contaminated and uncompostable materials <br /> will either be returned to the hauler or placed in bins located near the receiving areas. <br /> Odor Control: The compost industry has proven that with proper management <br /> techniques and use of appropriate tools, offensive and nuisance odors can be <br /> controlled. Odor emissions from the green material feedstock will be minimized through <br /> proper management of the windrows and storage piles in terms of time, temperature, <br /> moisture, turning to maintain aerobic conditions, and proper carbon-to-nitrogen (C:N) <br /> ratio to reduce ammonia levels. The consistent monitoring of the active compost will <br /> F maximize the aerobic decomposition. Maintenance of the optimum moisture content <br /> and application of water will enhance and expedite aerobic decomposition and minimize <br /> odor emissions. Placement and maintenance of buffer zones and exterior landscaping <br /> may further mitigate odor impacts. Excessive odors from the CTI system are not <br /> anticipated due to its enclosed and aerated nature. j <br /> The new Compostable Material Handling regulations effective April 4, 2003 require that <br /> an Odor Impact Minimiz <br /> ation Plan (OI <br /> MP). The OIMP ' <br /> s provided as an attachment <br /> this locum to <br /> document. <br /> Dust Control: The primary sources of dust at the facility include the truck traffic,. <br /> material turning, and material screening. The primary means of dust control at the <br /> compost facility will be by water truck. Periodic watering of roads and aisles between <br /> windrows will minimize dust from incoming vehicles. Maintaining appropriate moisture <br /> levels in the windrows during aeration will also help alleviate dust. The Tracy MRF & TS <br /> will avoid screening finished materials during periods of high winds to minimize dust <br /> creation and dispersion. Processing or movement of materials will be halted in high <br /> wind conditions. Good housekeeping measures are practiced, like regularly clearing <br /> roads and windrow aisles of spilled material and any blowing litter. Processing <br />�I equipment uses water spray as appropriate to reduce dust. <br /> f <br /> Noise Control: Noise is controlled through the proper use and maintenance of mufflers <br /> and noise suppression systems on equipment. The below grade nature of the site, <br /> elevated roadbed and surrounding windrows should attenuate equipment noise. Noise <br /> from the CTI blower motors or aeration fans is not anticipated to be a significant noise <br /> source, as evidenced from operations at other facilities over the last five years, even <br /> with the addition of another blower per bag with the increase in bag size. <br /> Edgar&Associates,Inc. 26 <br /> Tracy Compost Fac ProlDesc042310 <br />
