<br />P•1r. Scott Briggs <br />February 18, 1980 <br />Page -4- <br />Please demonstrate that the vegetation being planted will <br />maintain itself and regenerate without continued dependence <br />on soil amendments or fertilizer. In other words, since <br />there is no organic matter in the growth medium to be <br />used and none will be added, show proof that the soil will <br />be able to provide all necessary nutrients. <br />3) It is our understanding that the soil sample analized <br />by C.S.U. was actually not topsoil but some lower horizon <br />of subsoil nor is it the growth medium that will be used <br />in revegetation. To our knowledge no analysis was done on <br />the material that will actually be used as the growth medium <br />for revegetation. We must have a soil anlysis of the material <br />that will actually be used as growth medium. <br />4) Apparently the mining operation results in excess fines, <br />how will all of the fines be handled? <br />G. Exhibit J - Vegetation <br />1) P-J-1 - Please state the percent density of the native <br />plant communities. <br />2) Since such diverse vegetation communities exist, this <br />information should be portrayed on a vegetation map. <br />H. Exhibit L - Reclamation Costs <br />1) What is the maximum amount of backfilling (in cubic yards) <br />which would be required at any one time? <br />2) Soil Preparation - $110/acre. <br />3) Please figure the costs fora minimum of 3 waterings/ <br />season for 3 years to establish the trees and shrubs. <br />4) Please figure the costs for the quarry and staging areas <br />separately. <br />5) The leveling and grading figure appears much too low. <br />I. Exhibit M - Local Government Approval <br />1) Need zoning how Colorado Springs, Colorado and proof <br />of U.S. Forest Service approval. <br />J. A general concern is the lack of specificity in this restated <br />application compared to previous documents. <br />Examples of this problem where more details were available occur <br />in the following areas: <br />1) Soils analysis from CSU; <br />i ...... ~ ~ a ~ <br />
