' r 1 Mid-Term Review 30 November 27, 1985 the permit. In addition, due to the harsh climate of the area and the difficulty in successfully reestablishing vegetation over reclaimed areas, a 50% reseeding cost should be added to the estimate. This added cost can be removed from the bond upon adequate demonstration that first-time seeding efforts are successful . Fill compaction - Page V-30 of the permit application indicates that all fill areas "will be recompacted to 90% maximum dry density (AASHTO spec. T99-74 or equal) in lifts no thicker than are foot to provide positive stability." As such, an estimated cost for compaction machinery at an appropriate number of hours needs to be added to the earthwork calculations; Sediment Ponds - The cost estimate provides for removal of ponds DP-1 and one of the refuse area ponds, but does not appear to provide an estimate for the cost of removing the remaining sediment ponds at the mine (ponds PP-1, SS-1, SS-2, RP-2, 3, RP-4, RR-1, RR-2, and RR-3). Also, reclamation of the ponds must include replacement of topsoil and revegetation; Halandras Dump - An estimated cost of reclaiming this area needs to be added to the estimate. Reclamation of this area will involve backfilling the open pit, replacement of all salvaged topsoil and revegetation; Topsoiling - Page V-32d of the application refers to a Table V-4 which shows proposed volumes of topsoil to be stripped from affected areas and replacement depths over regraded areas. However, this table could not be found within any of the Division copies of the application. Additionally, Page V-32d of the permit states that "on slopes of 3h:ly or steeper the topsoil will be spread and furrowed on the contour to retard erosion ". The estimate cost of providing contour furrows over the topsoiled areas should be added to the reclamation cost estimate: Refuse Disposal Areas - Page IV-44 of the permit states that "After reclamation has been completed and the sediment ponds have been removed, the permanent diversion ditches will be extended to drain into the natural drainage as shown on Map 81." As such, an estimated cost of extending the ditches should be added to the reclamation costs. Once the reclamation cost estimate has been revised and accepted by the Division, the final set of calculations will need to be incorporated into the appropriate portion of the permit application.
