Bondinc - Rule 3.02.2 <br />36. The Division is re-calculating Colorado coal bonds to provide adequate <br />monies to reclaim the coal left in stockpiles. The permit application <br />currently lists coal stockpile sizes on pages 7, 2.05.3-13, 2.05.3-16R,, <br />2.05.3-27R, and 2.05.6-3. The maximum stockpile tonnages are listed as ' <br />follows: <br />Stoker Coal- 3000 tone <br />Open Product/Raw Coal - 7500 tone <br />Clean Coal - 45,000 tone <br />Loadout - 500,000 tone <br />Provide a plan to reclaim 509 of the maximum storage volume. Assess the <br />bond required to achieve this plan and incorporate it into the bond <br />calculation. <br />37. Develop cross-sections and a material balance analysis to evaluate the <br />backfilling and grading plan at the loadout, to ensure that reclamation <br />can be feasibly accomplished. <br />38. The last paragraph of page 13 continuing on to page 14 in Section 2.05.4 <br />states that topsoil pile M-1 has a volume of 10,000 cubic yards and that <br />topsoil pile M-5 will have a volume of 11,600 cubic yards which results in <br />a total of 15,200 cubic yards to be distributed over the facilities area. <br />The figures, literally, do not add up. Please correct. <br />39. The indicated seeding rate of 167 PLS per square foot in Table 33 is <br />almost triple the standard rate of seeding. Zt is recommended that <br />Southfield submit a change to the seeding rate to approximately 50-70 PLS <br />thereby saving some costa on the revegetation estimate. <br />40. In the bond estimate, overhead costs which include public liability <br />insurance, a contractor's performance bond, engineering fees, contract <br />administrative coats, as well as contractor profit and job superintendent <br />costa, were not consistently computed for each task. To address these <br />costs accurately, we recommend that rather than computing these costs for <br />each task, that after all direct costs have been totaled, the contractor <br />profit and administrative/overhead costa be calculated and included after <br />all direct costa are totaled. Generally speaking, contractor profit is <br />estimated at 109 of the direct coats, and overhead and administrative cost <br />between 109 to 129. <br />41. Tasks involving earthwork should include push or haul distances and the <br />elope of that distance to ensure consistent and reliable performance times <br />for any piece of equipment. Please address. <br />42. In conjunction with your response to question 11 (Stipulation 17) please <br />include a bond estimate for the rip-rapping of Magpie Creek's <br />reconstruction. <br />43. The section on the removal of the mine facilities needs to be revised to <br />show the coats for the removal of: <br />a. Rotary breaker building <br />b. Coal stoker conveyor <br />c. Explosives bunker <br />d. Pump house <br />e. WAL building <br />f. All culverts <br />g. Approximately 750 cubic yards of trash/wood/machinery <br />h. Main vent fans at the back of the warehouse/shop/office <br />44. The calculations for facilities removal include a section on miscellaneous <br />concrete removal. What specifically ie included in this estimate? <br />6 <br />
