solids present in the American Tunnel drainage. The ponds are de- watered by a decant system displayed in the decant system diagram found in Exhibit G of the mining permit application (see Appendix A-4) . The lands on which the ponds were constructed are within boundaries bonded by the permit application, and the disturbance classification has not been changed. Upon completion of operations at this site, the ponds will be dewatered through existent decants, and berms will be leveled and graded to slopes compatible with sur- rounding terrain. Revegetation of the excavated area will commence this year and re- clamation to a state reflecting pre-existent vegetation cover com- pleted in three years. Since native soils are existent, revegetation will require only the latter two phases of the reclamation plan, thus cost of revegetation can be absorbed by the original bond amount set for this operation. The primary species to be used for revegetation of the area will be Phleum pratense at a seeding rate of 30 lbs per acre. The second location at which additional acreage has been affected is the Terry Tunnel portal area. This area was not described in the application for regular operations because no measurable disturbance previously existed. The Terry Tunnel was driven long before Standard Metals began working the Sunnyside Mine. During Standard Metals' operation, the Terry Tunnel was used only as an emergency escape route from the Sunnyside Mine and no surface operations were con- ducted at this site. However, due to increased activity at this site, a moderate surface disturbance of approximately 2.0 acres (400 ft by 200 ft) now exists. _The major portion of this disturbance is due to an access road previously constructed, but recently graded, a park- ing area and small surface structures used for equipment storage and maintenance. The cost of reclaiming this area can also be absorbed by the bond amount set for the overall operation. Standard Metals Corporation submits to the Mined Land Reclamation Board a technical revision to add 3.2 acres of affected land having moderate to minor disturbance to previous affected lands totalling 140 acres and bonded at $347,543.00. Reclamation of these newly affected areas will not affect the total capital required for completion of reclama- tion efforts on lands presently bonded; thus, the present bond amount will cover reclamation of affected acreages totalling 143.2 acres. -9-
