-6- <br /> Section 5 - Bonding <br /> In reviewing the Mid-Continent bond, calculations were derived utilizing <br /> Jim Herron' s original assumptions for material volumes and equipment. Some <br /> questions exist with respect to these assumptions throughout the text below. <br /> The references used to calculate the bond were: Means Construction Cost Data <br /> 1985 for demolition; CAT Handbook 15th Edition for production; and 1985 Rental <br /> Rate Blue Book for machinery costs. <br /> I. Demolition <br /> The Division' s estimated demolition costs generally agree with the original <br /> estimate. However, the cost for specific items varies widely. Using "Means" <br /> produced significantly higher costs for the wash plant area, and significantly <br /> lower costs for the portals. Mid-Continent should re-calculate the sealing <br /> and demolition costs to account for this discrepancy. <br /> Demolition Costs <br /> No. 1 Mine $ 53,145.64 <br /> No. 2 Mine $ 27,994.56 <br /> No. 3 Mine $ 46,178.96 <br /> No. 4 Mine $ 37,556.33 <br /> No. 5 Mine $ 14,694.76 <br /> Pock Tunnel $ 12,839.89 <br /> Shop Area $101 ,686.80 <br /> Prep. Plant Area $303,101 .20 <br /> Refuse Disposal Area $ 6,900.00 <br /> II. Backfilling and Grading (B and G) <br /> B and G costs for the portal benches were calculated using all original <br /> assumptions. <br /> B and G costs for the wash plant area were based on the plan submitted to <br /> satisfy Stipulation No. 7 of the permit. This plan calls for possible <br /> importation of fill , but does not state how much fill needs to be imported, or <br /> where the fill will come from. In order to provide a conservative estimate, <br /> the Division assumed that the entire volume must be obtained from the Tunnel <br /> Muck refuse pile. Mid-Continent may wish to provide an alternate scenario and <br /> detailed cost estimate for the reclamation of the prep plant area. <br /> The original backfilling costs for the roads were based on decreasing the road <br /> widths from 22 feet to 11 feet. However, although the permit application <br /> states that the roads are 22 feet wide, field inspection and the 1983 Haul <br /> Road Report from Geo-Hydro Consulting indicates that the roads are 50-60 feet <br /> wide. The B and G costs for the haul roads are based on decreasing the road <br /> widths from 55 feet to 11 feet. The road length was taken from the Geo-Hydro <br /> report (14.74 miles). Mid-Continent may wish to provide an alternate, <br /> detailed backfilling plan. <br />
