2. FACILITY INFORMATION ................................................................................................................................................................................. 2.1 . GENERAL SITE INFORMATION Site Name: DTE Stockton,LLC. Address: 2526 W.Was in ton St. Stockton,CA 95203 Telephone: (209) 320-3700 EPA ID: CAD000359102 SIC: 4911 Length of Time: Facility operating for approximately 30 years; 6 years using woody biomass as fuel Employees: 34 Description: Biomass power plant 2.2. FACILITY DESCRIPTION DTE Stockton is a power plant using woody biomass as fuel.The raw materials used for this process are comprised of waste wood from sawmills,forest thinning produced in fire prevention,agricultural orchard removals,and urban wood waste.Woody biomass arrives via truck and is transported via truck tippers, conveyors,stackers,and reclaimers.The materials are reduced and screened to a consistent size to improve combustion. The biomass fuel is then dropped into a silo for combustion on the boiler.T e co ustion o io ass uel eats u ater to es to create stea which drives a steam turbine producing electricity. reen ener o er is sent to t e ri . 2.3. WASTE GENERATING ACTIVITIES As seen in Figure 4 in Appendix A,DTE Stockton's two (2)major waste streams are generated by the process of combustion of woody biomass in the boiler. Although there are multiple hazardous waste streams which are not considered major waste streams,nearly all of this waste can be attributed to routine maintenance at the facility. There are two (2) major waste streams that require source reduction evaluation-bed ash and fly ash. The following is a general description of the manufacturing process and the waste streams that are generated. 2.3.1. Routine Maintenance Truck tippers,conveyors,and stackers are used to transport woody biomass to the boiler for combustion,all requiring oil to operate.Spilled hydraulic and lubricating oils are collected with rags,which are contained and disposed of.Used oil can also be used as reclaimed oil for the reclaimer.The quantity of oily rags and debris hazardous waste is function of operating the truck tippers,conveyors,stackers used to transport woody biomass to the boiler for combustion,as well as the maintenance that is required for the equipment to operate correctly. Indirectly,increased or decreased business volume would affect this waste generation as well. Additional cleaning processes at DTE Stockton are necessary and critical to the health and safety of the manufacturing process.
