En"vironment;.lnc. Page 2 ~ A'Ibert;Frei ;and>Sons; Inc. ,Walstnim Aggregate Quarry M.L.R.B. Permit M-83-033 facing"slope"will be mined, but as committed too in the Reclamation Plan, it will be returned to at least its present state using plants native to the site. FYI, since Frei's purchased the Young property, no cattle have been placed on the nearly 1400 acres currently owned by the family.-.Over that time we have seen an increase in the quality 6 quantity of the"grasses and shrubs on the site. This has attracted more"wildlife, deer, elk, bighorn sheep and even a mountain goat. Finally this is private property and mining an additional 166 acres out of "1400, 'over"the next l00 years is .far less than other impacts that will occur to surrounding wildlife habitat, i.e., housing developments. 1. What I was, trying to explain here was that when mining reaches the north slope area that there would be 1,000 linear feet of partially-finished bench-slope needing backfilling. This was-not a .reference to the. total amount to,be found in the mine at that- -- time. When doing the reclamation cost estimate Z only estimated . what I"thought would occur at a given"point in time.. This estimate was done a time that occurs before mining reached the north slope area. 'The maximum highwall length may change as mining progresses thru the mine, so periodic bond evaluations will have £o be-done; as mining moves into a new area. As we discussed S will take two paths to determining what the bond should be set at. In the first I addressed the"Inspection report of April 2002 to determine what the current bond should be. In the second, I ,address how much it would take to bond the mine at a point approximately 10 year"from now. In the second calculation I spelled out the limits of the length of the highwall and total area of disturbance. The other restrictions require certain benching commitments on the new area and the amount of reclamation necessary to reclaim the mine if mining ended at that time. 2. Construction .of the lakes is proposed for the future. At this time it is not possible to'aequire the information needed to assess what activities or materials will be needed to make the excavated-areas into water storage reservoirs. Until that time, Frei will create two-areas deeper than the surrounding floor that will be .developed as part of the commercial floor area currently approved. The slopes going from the-main floor to the floor of the depressions will be .mined 3h to lv and the floors will be fairly level. 'Once the Frei Lake and Lake Albert areas are complete reservoir planning will-begin to determine if it is feasible to build them: Albert Frei and Sons, Inc., will submit .design documents as a permit revision to the Division prior to construction of the liners and. pump facilities, if needed. This duel Reclamation Plan allows the flexibility A.F.S.-needs and still assures that the bond will be adequate to cover reclamation costs. 3. This area is part of the sight berm that will be left along Highway 6. Some additional mining may take place on the north facing wall of this berm to narrow it as shown on the reclamation • map. IF mining returned to this area it would be mined last so it will limit visibility into the mine until that time. Mr. Revey discussed this walls stability on page 9 of 14, paragraph 3 of his report. As he noted "These walls, as shown in Figure 3.1 and 3.2. have been very stable.." .Albert Frei and Sons, Inc., does not plan to return to•this area until late in the mining sequence and if.that happened then this area-would have to be mined per Section 4.0 RECOMMENDED SLOPE'CONTROLS FOR THE WALSTRUM QUARRY of The i. ~ a,, ~ ~- ,;. ,:~~ Fs: ~''. r~,".~~::'.. _--a.sa,_is_.. <J.'r.E 'i' .xrt:is~._ .r.~ .~
