Report of Composting Site Information Tracy Material Recovery Facility and Transfer Station 30703 S. MacAurthur Drive, Tracy, Ca. 95377 of green material from commercial and residential sources when the generator is disposing of the green material in bins or at the curb in a pile. The soil will be stockpiled near the green material-tipping pad until such time there is sufficient quantity to transport the soil to the soil mixing area. Soils storage for use in the topsoil mixing would occur where there is available pace in the composting area. Soil that exhibits indications of chemical contamination based on odor, color, or texture will be evaluated by the Site Manager and returned to the hauler and/or sampled and tested by a state certified laboratory. Manufacturing topsoil is performed in a manner to match the market for which it is intended. Custom blends could be designed for golf courses, nurseries, and landscapers. The sources of the materials to be used in the custom blends would be the soil delivered on-site blended with compost. Other raw material that may be added includes sand, and spoils from on-site excavations. Depending on the blend, the desired amount of compost is delivered to the soil mixing area where the soil from the other sources has already been placed. A front-end loader blends the material while a water truck or piped irrigation system, when needed, is spraying the materials and the mixing process to control dust and to add moisture to the custom blend. The trommel may also be used to mix soils. After the mixing is finished, the soil is either loaded into a subcontracted transport vehicle for off-site deliveries, or it is transported on-site for storage until the material can be delivered to the market.

Materials are evaluated for acceptability and pertinent data as to type of material, source, weight and vehicle are recorded. Unacceptable materials are rejected. • Unloading - Acceptable materials are unloaded in a designated area and segregated by type such as yard waste, wood waste and salvageable lumber. Sorters check the loads for unacceptable material and contaminants. • Size-Reduction and Mixing - Materials are processed through a tub grinder where they are shredded and ground. Composting mixes are prepared in one process by alternating loads of various feedstocks into the grinder. 18
