Report of Composting Site Information <br /> Tracy Material Recovery& Transfer Facility <br /> 30703 S. MacArthur Drive, Tracy, Ca. 95377 <br /> Monitoring and Reporting procedures in conjunction with all requirements of the WDRs, <br /> under oversight of the Central Valley Regional Water Quality Control Board. <br /> Litter Control: The litter from the composting operation is not expected to be significant. <br /> The contamination found in green material is typically inert debris from the yard. <br /> Vehicles hauling green materials to the facility will be required to be covered if the loads <br /> are susceptible to loss of branches or other green material on the roadways off-site and <br /> on-site. Materials dropped on on-site roads will be routinely picked-up. The litter will be <br /> policed and removed from the facility's perimeter at least weekly or more frequent if <br /> necessary. Site personnel and facility users will be directed to use litter containers that <br /> will be provided for trash. Contaminated and uncompostable materials will either be <br /> 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 /> 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 ASP system are not <br /> anticipated due to its covered and aerated nature. <br /> The Compostable Material Handling regulations effective January 1, 2016 require that <br /> an Odor Impact Minimization Plan (OIMP). The OIMP is provided as an attachment to <br /> this document. <br /> Dust Control: The primary sources of dust at the facility include the truck traffic, material <br /> turning, and material screening. The primary means of dust control at the compost <br /> facility will be by water truck. Periodic watering of roads and aisles between windrows <br /> will minimize dust from incoming vehicles. Maintaining appropriate moisture levels in the <br /> windrows during aeration will also help alleviate dust. The Tracy MRF will avoid <br /> screening finished materials during periods of high winds to minimize dust creation and <br /> dispersion. Processing or movement of materials will be halted in high wind conditions. <br /> Good housekeeping measures are practiced, like regularly clearing roads and windrow <br /> aisles of spilled material and any blowing litter. Processing equipment uses water spray <br /> as appropriate to reduce dust. <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 aeration fans is not anticipated to be a significant noise source, as evidenced <br /> from operations at other facilities over the last several years. <br /> 23 <br />
