of waste excavation per crew per day was assumed. Based on this daily output, the time to excavate the landfilled wastes would be 390 working days or about 1-1/2 years. For cost item no. 3, Waste Transportation, it was assumed that the basic unit cost for truck transportation was $3.50 per loaded mile for a 20 cubic yard capacity covered gondola truck (U.S. Pollution Control, Inc. Personal Communication with Earl Finder). A 30-mile haul to Pine Bend Landfill was assumed for 80 percent of the waste and a 700-mile haul was assumed for 20 percent of the waste assumed to be characterized as hazardous. It should be noted that a cost savings of about $40 million could be saved if rail access to the landfill were available and wastes were shipped via rail.at unit cost of $100/ton. Cost item no. 4, Waste Disposal, Was calculated assuming that 80 percent of the landfilled wastes would be capable of disposal in another solid waste sanitary landfill such as the Browning -Ferris, Inc. (BPI) landfill in Pine Bend, Minnesota. It was assumed that the other 20 percent of the wastes would have.hazardous characteristics as determined by sample analysis (cost item no. 1) and would need to be disposed of in a Resource Conservation and Recovery Act (RCRA) regulated landfill for hazardous wastes. The unit costs for disposal were obtained from Mr. Mike Ayers of BFI and several hazardous waste landfill operators in Illinois, Indiana, Ohio, Michigan and Oklahoma. The volume of waste to be excavated was converted to tonnage for calculating disposal costs using the ratio of 2.5 cubic yards per ton of waste. Thus, 2.5 million cubic yards of waste was assumed to be equivalent to one million tons. It should be noted that if the non -hazardous solid wastes were incinerated off -site the cost for disposal would increase about $4,000,000 based on a unit cost of $70/ton for incineration including ash disposal.
