~~ 1G 550,000 for solid waste plan administrator/sit inspector Pros and Cons of Manual Construction Waste Sorting Facility Pros of Manual Facility: • Simple to build and operate • Less capital cost than asemi-automated facility • Ability to provide more potential market areas for source separated materials, especially dry wall Cons of Manual Facility • Higher cost per ton than other options _ Potentially dangerous working conditions for those manually removing materials from a tipping floor • Lower recovery rate than semi-automated facility, not likely to meet waste reduction goal • No experience with this type of facility • Relatively high capital cost This facility could also be coupled with a transfer station instead of a landfill for the residuals. 5. Semi-Automated Waste Recycling Facility: A semi-automated recovery facility has the potential to recover more materials than a manual facility. According to our estimates, such a facility is the only option that could divert a minimum 25% of construction wastes. Such a facility could be publicly owned or privately owned. Public ownership would require significant capital investment on the front end. Private ownership would entail foregoing the tipping fees and any other revenues associated with operating such a facility. There is also some risk of the operator importing out-of-county materials to improve the through put of the facility. As an alternative to a privately-owned facility, the Owners Group could consider construction of an in-house facility, as described below. See drawings in attachment 6a and 6b. Consideration of this facility would provide the opportunity to examine budget impacts from the costs of building such a facility. We have included some estimates of costs for owning and operating our own construction and demolition waste facility. It is possible that some of the initial costs could be reduced through tease or lease purchase of the equipment. We believe these are conservative cost estimates. We have prepared a preliminary design and cost estimate for a possible facility (atta :hment 5). We have estimated potential capital-costs of such a facility at $1.55 million including stationary equipment and rolling stock. We base this estimate on information gained from reviewing some existing facilities, acquiring quotations to construct a facility and our own experience owning and operating equipment similar to that required for such a facility. The costs of the manual facility in option four are based on these estimates below with option 4 showing a smaller building 100x 200 instead of 100 x 300), no conveyor belt or trommel screen and• one less staff member for manual. picking. Equipment maintenance costs are significantly greater in asemi-automated facility than a
