The above list of equipment ie standard, readily available earth-moving <br />• units which are sized to perform the maximum tasks required for the reclamation <br />processes involved. They are either owned by the applicant or are available locally <br />for hire at hourly rental rates. They may also be utilized upon a unit of work <br />performed basis. Other makes and sizes can perform the work required and, if various <br />equipment combinations are applied, the coat per cubic yard or acre reclaimed <br />(depending upon the appropriate reclamation unit) would be determined from the <br />prorated performance abilities. Due to the relatively small area involved and the <br />restrictions of confined working spaces, the availability/efficiency ratios of <br />earth-moving equipment will be much lower than are normally calculated under <br />conditions where maximum capacity can be obtained. This results in a higher cost per <br />unit work accomplished. <br />Summary of Equipment Costa for Reclamation <br />(See Table RP-1) <br />Bulldozing - Backfill <br />• Tractor cost of $90/hour from mobile equipment. Performance is <br />influenced by working conditions which require pushing backfill material up an <br />ever-increasing gradient as the highwall is filled. Access to the fill is available <br />only from the lower edge of the portal bench as filling proceeds. Backfilling the <br />roads between Hubbard Creek and the portal bench will require precise, deliberate <br />operation of equipment due to both side-slope considerations and the need to salvage <br />as much SPGM as possible from the material originally disposed on the berm during <br />initial road construction. Supplementary use of the front-end loader will aid in <br />distribution and transport of this material. <br />Productivity of the tractor will vary a great deal from handbook <br />performance standards, hence, volumetric coats have been estimated as follows: <br />Tractor Travel Speed = 2 mph on portal bench <br />1 mph on access road <br />Tractor Blade Capacity = 14 cubic yards <br />• Average Travel Distance = 300 feet on portal bench <br />75 feet on access road <br />1143 <br />(Rev. 1-22-82) <br />
