jl Project Description— Report of Composting Site Information , Tracy Materia/Recovery Facility and Transfer Station 30703 S. MacArthur Drive, Tracy, California 95377 Litter Control: The litter from the composting operation is not expected to be I significant. The contamination found in green material is typically inert debris from the yard. Vehicles hauling green materials to the facility will be required to be covered if the loads are susceptible to loss of branches or other green material on the roadways off- site and on-site. Materials dropped on on-site roads will be routinely picked-up. The litter will be policed and removed from the facility's perimeter at least weekly or more 11 frequent if necessary. Site personnel and facility users will be directed to use litter containers that will be provided for trash. Contaminated and uncompostable materials will either be returned to the hauler or placed in bins located near the receiving areas. I Odor Control: The compost industry has proven that with proper management E techniques and use of appropriate tools, offensive and nuisance odors can be controlled. Odor emissions from the green material feedstock will be minimized through i proper management of the windrows and storage piles in terms of time, temperature, moisture, turning to maintain aerobic conditions, and proper carbon-to-nitrogen (C:N) ratio to reduce ammonia levels. The consistent monitoring of the active compost will maximize the aerobic decomposition. Maintenance of the optimum moisture content and application of water will enhance and expedite aerobic decomposition and minimize odor emissions. Placement and maintenance of buffer zones and exterior landscaping may further mitigate odor impacts. Excessive odors from the CTI system are not' anticipated due to its enclosed and aerated nature. i q The new Compostable Material Handling regulations effective April 4, 2003 requite that an Odor Impact Minimization Plan (OIMP). The OIMP is provided as an attachment to this document. Dust Control: The primary sources of dust at the facility include the truck traffic, material turning, and material screening. The primary means of dust control at the compost facility will be by water truck. Periodic watering of roads and aisles between windrows will minimize dust from incoming vehicles. Maintaining appropriate moisture levels in the windrows during aeration will also help alleviate dust. The Tracy MRF & TS will avoid screening finished materials during periods of high winds to minimize dust creation and dispersion. Processing or movement of materials will be halted in high wind conditions. Good housekeeping measures are practiced, like regularly clearing i roads and windrow aisles of spilled material and any blowing litter. Processing equipment uses water spray as appropriate to reduce dust. i Noise Control: Noise is controlled through the proper use and maintenance ofufflers I and noise suppression systems on equipment. The below grade nature of the site, I elevated roadbed and surrounding windrows should attenuate equipment noise. .'Noise from the CTI blower motors is not anticipated to be a significant noise source, asl evidenced from operations at other facilities over the last five years, even with the addition of another blower per bag with the increase in bag size. j r Vector Control: Vectors are animal, insects, and other organisms that may carry pathogens, such as mosquitoes, birds, flies, and rats, from one host to another.
