Transfer/Processing Report Tracy Material Recovery and Transfer Facility 30703 5. MacArthur Drive, Tracy, California 95377 stream. A closed water loop is used for cooling as well as to provide a seal to the bottom of the gasifier. Water slurry level is maintained in a tank and pumped to an automated filter. The automated filter is typical for river sludge treatment and separates the solids from the recirculated water. The char byproduct, also called biochar, is separated out using a special mechanical separator and periodically tested prior to resale as a soil amendment, sequestering carbon in the ground in solid form for up to 1,000 years. Water leaving the filter is passed through a final stationary filter prior to heat exchange. The scrubbing water is absorbing heat from the product gas and must be cooled in a cooling tower prior to returning to the closed-loop scrubber. Material Storage There are numerous storage areas for recovered and recycled material on-site: • Baled storage on paved surfaces outside of the MRF/TS building. • Baled Stroage under the proposed Canopy • Storage areas for the higher commodity priced baled materials will be located inside the expansion area of the MRF/TS building. • Finished compost on the finished compost storage stockpile area at the north end of the compost pad. • Processed inert products, including 3/ inch AB specification or 3/8 inch utility sand, at the Inert Processing Areas. • Recovered wood, metal, drywall, white goods, and residual debris adjacent to the C&D Processing Area. Household Hazardous Waste, Universal Waste, and Electronic Wastes Household hazardous waste will be collected as part of the load check program at the Material Recovery Facility, the Transfer Station, the Composting Facility, the C&D Processing Operations, and the Inert Processing Operations. HHW, including latex paint, used oil and oil filters, and antifreeze, would be stored during regular business hours by personnel at a location within the MRF/TS Building in the method described below. The facility will not intentionally accept or store hazardous wastes, including batteries, oil, paint, and special wastes, unless it has been approved to handle the particular waste by the appropriate regulatory agencies. Such approvals shall be placed in the operating record. Should unauthorized hazardous wastes be discovered, control measures as necessary to protect public health, safety and the environment will be implemented, such as elimination or control of dusts, fumes, mists, vapors or ® gases shall be taken prior to isolation or removal from the operation or facility. 16
