The source of fill for Lake Emma in the Consolidated Permit was to <br /> be "waste rock and talus from the land adjacent to Lake Emma" and in Amend- <br /> ment 03, waste rock from dump No. 2. The temporary storage of the waste <br /> rock close to the hole was based on the premise that a plan approved by <br /> the Division could be worked out to use the material as backfill in the <br /> hole. This assumption is based on the fact that the reclamation plan for <br /> backfilling the hole (Consolidated Permit or Amendment 03) is unrealistic <br /> if this or similar material cannot be used. <br /> Sunnyside has investigated the use of a bactericide (Pro Mac) for <br /> inhibiting the acid-generating process in the temporary waste stockpiles <br /> until final disposition. Representatives for the product believe this would <br /> be an effective use of the product and inhibit acid formation until final <br /> deposition. <br /> The BLM conducted its cultural resource inventory at the site. <br /> Sunnyside salvaged 1574 cubic yards of topsoil (surveyed volume) from <br /> the sites to be disturbed. The topsoil is in stockpile areas, graded and <br /> seeded with signs designating their location. Plans for usage of the topsoil <br /> have not been formulated yet for review by the Division and the BLM. <br /> Final disposition of the waste generated is planned for the Lake Emma <br /> void but will not commence until approved by the Division. <br /> Sunnyside has engaged J.F.T. Agipito & Associates, Inc. to assess the <br /> final pit wall stability. A preliminary site visit was made and an evaluation <br /> will be submitted prior to excavation of the third mine bench. <br /> Sunnyside has placed survey monitoring monuments above each pit and <br /> on disturbed terrain to monitor relative erosion rates. <br /> We believe our efforts comply with the stipulations and basic provisions <br /> of the permit although our line of communication with the Division in the <br /> past has been lacking. We are willing to work with the Division to <br /> satisfactorily address the remaining portions of the stipulations or any <br /> other problems that might arise as the "open pit project" matures. <br /> Sincerely, <br /> Larry Perino <br /> Superintendent - Technical Services <br /> cc: Camille Ferrell, MLRD <br /> LP/dp <br />
