<br />• ~`.05.~2)fc) B,T ackfilling and GradinE (continued) <br />Mine yard area <br />The mine yard area was reclaimed to the approximate original contour in 1992 although <br />its final elevation was approximately 5 to 8 feet higher than the pre-mining elevation. <br />At the request of the landowner (see pages 187.1 a-b), the building and access road are <br />to remain after reclamation for storage of ranch equipment, etc. <br />Once Phase 2 bond release is granted, the following items will be undertaken in [he <br />yard area: <br />1) The sediment pond dam will be dozed down to the level of the bottom of the <br />emergency.spillway. All dozed material will be placed in the adjacent pond to fill it to <br />the level of the bottom of the spillway. The available material from the dam is <br />approximately 2.3 feet depth x 11.0 fee[ width x 160 feet length = 4048 cu.ft. or 149 <br />cubic yards. A small D-4 type dozer will be used [o complete the work. <br />2) TopSOil from the existing access road and swing out area in front of the building <br />door will be•excavated and placed on top of the backfilled pond area. The excavated <br />material will be 0.5 feet x .15 acres = 3267 cubic feet or 121 cubic yards. This can also <br />be done with a small dozer since the access road is adjacent to the pond. <br />~• 3) The'east berm will be excavated to the same level as the existing field. This material <br />is very gravelly and will make good roadbase, therefore, it will be placed on the access <br />road to. replace the topsoil that was excavated. The current berm is approximately 14 <br />feet wide and averages 1.6 feet high. The approximate volume is 1.6 ft x 14 ft x 210 ft. <br />= 47Q4 cubic feet or 174 cubic yards. A small 5 to 10 yard truck and small loader must <br />`b'e used to load and place this material. The 174 cy is slightly greater than the 121 cy <br />of topsoil removed from .the road, therefore, any excess,.will be used to raise the road <br />with a slight crown in the center which is better for future road runoff handling and <br />maintenance. <br />4) The areas of the berm, sediment pond and upper part of the dam will be re-seeded <br />according to the approved plan. This total area is approximately 0.24 acres for the pond <br />and dam, 0.07 acres for the east berm. The west berm has been contoured to blend into <br />the terrain and will not be re-disturbed. <br />All of these items are shown on the Final Contour Mao which is enclosed following <br />this page <br />183 <br />.~ <br />Revised 3/21/01 <br />r~~ <br />
