.' 8 posal of such wastes should be formulated. Any hauler contracts should reflect an appropriate share of responsibility for hazardous waste management. ~ OPERATIONS (CRITERION 6) Waste Energy Systems was established by Midwest Asphalt Corp. in 1982 to develop this project. Because of its limited experience, it has contracted with Thermal Reduction, Inc., of Bellingham, Wash., to: 1) develop the facil- ity; 2) operate it and provide in-service training for the first year to Waste Energy Systems staff; and 3) conduct quarterly monitoring inspections during the second and third years of operation. Thermal Reduction, Inc., has devel- oped its own 100 TPD facility and successfully operated it for 15 years. It is currently undergoing an expansion of capacity to 200 TPD. The firm operates other combustion facilities under contract in Alaska, Idaho and California. This arrangement should provide the ability to properly operate and maintain the facility. During the past 25 years, Consumat Systems has constructed more than 30 currently operating facilities. It has a reliable product. The facility will operate 24 hours per day. Unauthorized access will be con- trolled through staff observation and by locking unattended entrances. If steam output is interrupted, the energy users ~ill start standby boilers that are constantly warmed from normal output. Operational delays for interrupted steam customers should not exceed an hour in such circumstances. ~ ~ ECONOMIC EFFECTS (CRITERION 8) The impact of the proposed facility on solid waste service costs appears to be reasonable. The estimated capital cost of $8 million to $9 million is in line with those,of similar facilities. The projected tipping fee of $25 per ton is somewhat higher than current landfill rates but less than those associated with larger publicly developed systems. No public subsidies have been proposed for the project. The facility should minimally impact surrounding land use development of light industrial uses. Normal hauler traffic is not expected to exceed 20 trucks to and from the facility each day. If small five-ton packer trucks were used, truck traffic would still be less than 45 per day. Enclosed operations should present a neat appearance. CONCLUSIONS 1. The facility should have desirable waste management impacts. It should help achieve central processing objectives without impairing local strat- egies for waste reduction and source separation. Waste supplies should closely match processing capacity because of decisions excluding corre- sponding tonnages from waste designation authority. Waste Energy Systems should, however, explore opportunities for waste supplies closer to the facility in the future. 2. The facility design and location is acceptable. The system design has proven to be reliable in many installations. The local land use plan can be revised to permit the facility in conformance with regional policies. 3. The facility should have acceptable environmental impacts. Air emissions are not expected to create significant health risks, but the MPCA should
