INTRODUCTIOM In the early 1900 ' s, Stockton Scavenger Association collected solid waste in horse-drawn wagons. It was common practice to dump the contents of the loaded wagons into an auxiliary vehicle for trans- port to a disposal site. However, with the advent of the modern motor truck and the availability of low cost fuel, transfer opera- tions were abandoned and direct hauling was adopted. Today, with rising labor, operating and fuel costs, a transfer station is being proposed to reduce costs and the consumption of fuel. The decision to construct a transfer station is based on economics. It is cheaper to haul wastes in large increments rather than small in- crements over a relatively long distance. In order to improve existing collection and disposal practices and to continue its activities in resource recovery, Stockton Scavenger Association, Inc. , has retained the firms of Garretson•Elmendorf- Zinov•Reibin, Architects and Engineers, and Brown, Vence and Associ- ates, Energy and Environmental Engineers, to investigate the feasi- bility of a phased Transfer/Resource Recovery Facility. Scope of work The purpose of this study is to provide preliminary design of a solid waste management facility that can be implemented in stages . Phase I includes a refuse transfer station, public recycling center, relocation of SSA' s existing baling operation, and an office/ reception area. In Phase II, a facility to recover ferrous metals and produce either steam or electric power from the refuse is added. Preliminary designs and cost estimates are developed, and technical, economic and environmental assessments are made. Conclusions and Recommendations • SSA should pursue the immediate development and imple- mentation of a Direct Dump Transfer Station. As a result of implementing the Transfer Station at a capi- tal cost of $3, 272, 000, savings to SSA are estimated to be $190, 000 and 133,000 gallons of fuel oil annually. The public, by reducing the distance to disposal, is estimated to save r1R7 ,000 and. 73 ,000 gallons of fuel oil per year. A Transfer Station allows for more efficient resource recovery opportunities as markets develop. • A Resource Recovery facility could be added to produce steam at an estimated cost of $5, 377, 000 . Additional costs for electric power production are estimated to be $630, 000 . While this is a large capital expenditure, the income from the sale of recovered products (i.e. , steam and/or electricity) and savings from transfer and landfill rra- offset the costs of the energy facil- ity. In addition, net energy created from the processed solid waste is estimated to be equivalent to 2 ,000 ,000 gallons of fuel oil annually. Therefore , it is recom- mended that a detailed feasibility study be given con- sideration by SSA. - 1 -
