• phases of reclamation will have the final pit areas totally reclaimed before the roads and parking lots <br />aze recleaned. Therefore, the material will be ripped and dozed and configured in place. <br />Finish/Final Grading <br />This task represents final grading (versus rough grading) of backfilled pit areas. It includes such <br />things as knocking down small piles and/or ridges of spoil that may have been missed during the <br />rough grading process (when bulk earth movement, in the quickest manner possible, is the goal). As <br />with the other motor grader tasks above, this was traditionally a dozer task. In fact, at one point <br />SCC included an additional 10% of all rough grading hours for Enal grading. Again, based on <br />negotiations with SCC several years ago, this was changed to a motor grader task. <br />raina¢e Control Svstem Removal Construction <br />Removal includes all of the ditches on the site, including those that report to a sediment pond and <br />those that carry sediment pond discharge to a receiving stream. Again, this was traditionally a much <br />• more detailed dozer task group that was changed ro a motor grader task based on negations with <br />SCC several years ago. Also included is the removal of all sediment ponds. This is a dozer task that <br />removes the pond embankment and forms the final drainage. <br />The construction portion consists of the time and materials cost to install/construct the remaining <br />postmine drainage channels not in place as of August 25, 2004. The steps required aze excavation of <br />the channel, installation of a geo-textile and then placing riprap of a determined size over the geo- <br />textile. <br />Topsoil Replacement. <br />Topsoil replacement volumes were based on the maximum volume of material placed in stockp$es <br />over the life of the permit. The estimated volume in each stockpile was based on surveys and/or the <br />average topsoil salvage depth per soil type over a parrit-iilar azea (aces). The Division used topsoil <br />volumes that were in the Yoast Permit document. The correct topsoil volumes (the ones that the <br />Division used in recalculating the reclamation cost estimate) are a hybrid based on the 1999, 2001 <br />and 2002 Annual Reclamation Reports. This will result in an increase in topsoil replacement <br />• volumes from 777.9 ace-feet (used in the RN-02 estimate) to 826.8 acre-feet (used in the <br />recalculation). This is necessary because the Division must keep costs associated with ALL topso$ <br />replacement until a phased bond release application is submitted and approved.
