Odor Impact Minimization Plan —Compost Facility Tracy Material Recovery Facility and Transfer Station 30703 S. MacArthur Drive, Tracy, California 95377 • Section 1 — Method 1: Elongated Windrow Composting (green material only) The TMRF/TS & CF proposes to expand food waste feedstocks and propose the following composting methods — identified by their respective technology application section from the Report of Composting Site Information (RCSI) prepared as part of the project description for the Conditional Use Permit application, for the associated feedstocks: • Section 2 — Method 2: Elongated Windrow Composting (co-collected green material with up to 15% food waste) • Section 3 — Method 3: Covered Aerated Static Pile Composting (up to 40% food waste) Operations Plan for existing composting operations — Section 1 — Method 1: Elongated Windrow Composting (preen material only) The total time the green material feedstock remains at the facility using the elongated windrow composting method is approximately 14 to 20 weeks. The finished product is then stored on-site for not more than 180 days until the product is shipped off to market. There is adequate room on-site to store the finished product for extended periods. The Site Plan provides capacity totaling 68,700 cubic yards of total compost material, and 28,900 cubic yards of finished, stockpiled product. It is anticipated that the facility will process up to 115,000 cubic yards of material per year through the facility. Factors that influence throughput consist of adequate appropriate feedstock, material bulk density and moisture content, availability of new or additional feedstock sources, and market demand. The Compost Facility was originally designed to have sufficient capacity to receive and process 170 tons per day over an area of 5 acres, with peak loads up to 180 tons per day. The Environmental Impact Report prepared in 1993, when the Conditional Use Permit was obtained from San Joaquin County, anticipated a throughput of 132 tons per day of green material and wood waste. Current operations consist of an input of approximately 35 tons per day of green waste and 35 tons per day of wood waste. An overview of the windrow composting process is presented below: • Incoming trucks are received and weighed at the scale located near the Gate House. The scale personnel will direct haulers to the appropriate area of the composting facility. Appropriate signage in conformance with the requirements of 14 CCR §17867(a) (7) will be placed within the composting facility. 4
