with the final progress payment for the work if demobilization has been <br />completed. If the price bid for mobilization and demobilization is greater <br />than 15 percent (15°0> of the total contract price, invoices supporting the <br />mobilization costs will be required before payment is approved. <br />Remobilization <br />If remobilization becomes necessary due to seasonal conditions beyond the <br />CONTRACTOR'S control, remobilization costs will be paid based on documented <br />actual costs. No remobilization payment will be made if delays necessitating <br />remobilization were the CONTRACTOR'S responsibility. <br />TASK 2. PIT HIGHWALL GRADING AND OTHER EARTHWORK <br />DESCRIPTION <br />A. Orphan Pit <br />Reclamation of the 125-foot diameter, 30-foot deep Orphan Pit and the <br />associated 30-foot high, 400-foot long highwall to 2:1 (H:V) will involve <br />the import of approximately 6,800 cubic yards of material and a cut of <br />14,000 cubic yards (Map 2 and Exhibit 1). Approximately 3000 cubic yards <br />of concrete and coal waste will be moved 2800 foot south from the shop <br />area and 1000 foot south from the haul road. These materials shall be <br />placed at the bottom of the pit. Roughly 800 cubic yards of red rock <br />clinker will be moved 2100 feet south to the Orphan Pit. Roughly 14,000 <br />cubic yards of material will be cut predominately from an area 600 feet <br />north of the pit and highwall. The balance of the material will be <br />topsoil, as described in Task 3. <br />The current configuration of the area is shown by Map 3; the final <br />configuration by Map 4. Backfilling must extend to the top of the <br />highwall on the west side of the pit. No highwall reduction or <br />disturbance above this highwall shall take place. Rough graded slopes <br />shall not be steeper the 2:1 (h:v). The high point (point area) between <br />the two low areas must be reduced to blend with the remainder of the <br />grading work. <br />B. Haul Road <br />The Reclamation Haul Road between County Road 93 (aka Curby Ranch Road) <br />and the Orphan Pit is approximately 2600-feet long, and 25-feet wide <br />(Map 2>. This road needs to be ripped south of the well manhole <br />following removal of any coal fines. <br />C. Tipple Pond <br />The tipple pond embankment (Map 2 and Exhibit 1) must be removed by <br />grading the approximately 2000 cubic yards of material across a 0.5 acre <br />area in a manner that achieves positive drainage to the east. <br />-6- <br />
