indahl & <br />2. Approximately 20 acres are currently disturbed that will <br />require topsoil or overburden (growth medium) <br />replacement. With 25,000 yards of overburden and 1,215 <br />cubic yards of "topsoil" left from the original stripping L_... <br />and approximately 32,266 cubic yards of overburden, a <br />deficit of approximately 6,000 cubic yards will exist. <br />This deficit will be made up of er.cess material from the <br />mining area included in the amendment. (Exhibit E 12-24" <br />available and 6-12" replaced). <br />With testing and proper amendments, topsoil and <br />overburden available may 6e used as a growth medium. By <br />using existing material from the original permit area and <br />excess from the amended area, sufficient medium will be <br />available for 12" replacement as originally agreed and 6- <br />12" as recommended in the amendment application. If at <br />the time of final reclamation, insufficient growth medium <br />is still not available, the operator will find another <br />source. <br />D. Er.hibit E - Reclamation Plan <br />1. The operator concurs with replacement of a minimum of 12 v <br />inches of topsoil as other growth medium on all lands <br />currently disturbed which require revegetation. <br />2. Some overburden is being sold by the operator as road v <br />base material, riprap and other aggregates. <br />3. The operator does not contest the random planting of <br />cottonwood, American plum, Golden current, Chokecherry v <br />and Mt. Mahogany seedlings. <br />4. The operator concurs with the staff recommendation to <br />drop the commitment for irrigation of upland areas. <br />Since the current permit and lease only require grazing /~ <br />on the lower area, no irrigation requirement will be <br />initiated. If and when the lease is changed to irrigated <br />meadow, the operator will initiate a technical revision <br />for the Board's consideration to change the seed mir, to <br />hay meadow with irrigation. ` <br />5. The operator agrees to insuring that the grading of the / <br />bottom lands adjacent to the Creek will 6e such that the <br />drainage will be in a generally downstream direction. <br />.i 0 K <br />n 6.
