Transfer/Processing Report Tracy Material Recovery and Transfer Facility 30703 5. MacArthur Drive, Tracy, California 95377 loading pit. Drains are in place at the end of each ramp to collect the storm water and pump it up to the storm water collection system. Liquids from the loading pit area will be managed as wastewater. The amount of liquid will be minimized due to the drainage controls at each end of the ramp and the covered loading bays where rain water will be directed away from the loading bay. Some liquids may be generated off the tipping pad even with the slightly concave design of the floor. The final design will allow the contact liquids from the loading pits to flow through a clarifier to remove solids, then to an on-site storage tank. The tank will be pumped as frequently as necessary to prevent overflow. Wastewater from the tank will be pumped and transported to an offsite sanitary sewer dump station or directly to a POTW in the local area. No storm water or free liquids will be disposed of in the proposed or existing septic system. Only toilets, sinks, and other office or locker room type facilities will be drained into the septic systems. Dust Control Incoming and outgoing traffic, as well as the transfer of materials, have the Dust in the trailer loading area of the MRF/TS building will be controlled using a misting system. Traffic areas of the site will be paved with concrete or asphalt concrete and thereby reduce the generation of dust. Manual watering of the Composting Facility and the C&D/Inert Processing Area is done to control dust. The watering is done using handheld hoses or by a dedicated water tender. As necessary, employees water the green material, wood waste, and C&D material as it is unloaded from collection trucks and reloaded into the transfer trucks. The water spray is mostly absorbed by the material. The material is not sprayed so much as to generate runoff from the debris piles. Odor Control Odor controls shall consist primarily of rapid waste removal. As discussed above, refuse shall be stored at the station for no more than 48 hours. Normal storage time anticipated at the station is no more than a few hours. Minimizing waste storage at the station combined with daily sweeping and periodic wash down of the tipping floor, to eliminate residue build-up, will eliminate the source of any potential odors. A Standard Operating Procedure (SOP) plan has been prepared. This SOP addresses the reduction of the generation and emission of odors from the facility. A misting system is installed within the MRF/TS building over the trailer loading area to minimize the potential of odor and dust problems. The misting system will be outfitted with the ability to convey an enzyme based odor neutralizer should odor become a seasonal problem during periods of extreme heat. 27
