4. Due to the limited size of the Chimney Rock Mine and this proposed reclaiming operation, support equipment would not be required to operate a full shift each day. This was the case when Chimney Rock Mine was operating at full production and would certainly apply to this bonding/ reclamation plan. Proposed usage of the support equipment is as follows: Grader/water truck - operated alternately throughout the shift by a single operator. Grading of the haul road's entire length requires approximately one hour. Therefore, one circuit with the grader would be made morning, noon and afternoon with the water truck being operated between grader circuits. An additional hour per shift was assigned to the grader for miscellaneous operation. Service truck - Operated for two hours pre-shift each morning by the grader operator for servicing of the loader and dozers, then driven to a central location and parked. The haul trucks, water truck and grader would each stop sometime during the shift with each operator servicing his own equipment. The service truck itself does not operate during this time since the compressor and pumps run independently of the service truck. The service truck is operated one additional hour by a dozer operator for return to the shop area and refill of fuel and oil. An additional hour per shift is assumed for miscellaneous operation. Pickup truck - Operated by the field superintendent for travel to and from the job site, and for inspection and supervision of operations. An estimated one hour each morning and afternoon would be spent inspecting the field operations with the pickup operating. A one-half hour trip to and from the job site plus one hour of miscellaneous operation are assumed each day. The total operating hours per shift assumed for each piece of support equipment is summarized on Page 1 of the Revised Bonding Spreadsheet. Blue Book operating costs are applied per operating hour of each piece of support equipment (see Operating Cost Table page 4). Rental rates on support equipment are monthly charges and are applied regardless of the hours a piece of equipment actually operates provided equipment hours do not exceed 176 hours per month as stated in the equipment rental agreement. Support equipment rental costs are provided on page 4 of the Revised Bonding Spreadsheet. 5. A swell factor of 20 percent has been assumed for the compacted facilities area bench material.
