Permit # M-77-020 AUG 14 1997 ~~ e~~A :..e .....~.. o. o DELTA 874-9159 Division of rvhinerais 8 Gec~oc~y This letter is to respond to your observations and to the problems noted in the inspection report. As you are now aware we filed an amendment to this mining operation on July 21, 1997. This amendment may have addressed some of your observations, particularly the bonding and reclamation issues concerning bank sloping. I will supply a short response to the observations in the order presented and then explain what we have done on the problems. OBSERVATIONS • As you noted Phase 2 is nearly mined out. That is why we have amended the permit to increase the size of the mine and extend its life. The amendment also takes out the Staging/Phasing part of the plan so the site can be mined more efficiently and the islands were removed from Phase 1 because we did not have the material to wnstruct them. We began grading and shaping on the slopes shortly after your inspection and are nearly finished on the north, east and south areas. The west side sloping will be done by the end of the month. Topsoiling on the slopes that will not be disturbed later will be completed by the end of the year. • We prepared a new bond calculation work sheet as part of the amendment. This estimate included the cost to dewater the lake, slope the highwall and resod the area. Review of that document in the amendment submittal will help address this observation. The removal of the phasing is accomplished by limiting the amount of area that can be disturbed at any one time. • Please see the amendment submittal and the response above.
