<br />STATE OF COLORADO <br />Roy Romer, Governor <br />DEPARTMENT OF NATURALRESOURGES <br />MINED LAND RECLAMATION DIVISION <br />OAYID C. SHELTON, Dkector <br />DATE: May 28, 1987 <br />T0: Jordan or Jone Burdick <br />FROM: Carl B. Mount <br />RE: File No. M-87-042 <br />Adequacy Items <br />The following items must be addressed by the applicant in order to satisfy the <br />applicable requirements of C.R.S. 34-32-101 et seq. Mineral Rules and <br />Regulations of the Mined Land Reclamation Board- <br />Exhibit C - Mining Plan <br />1. We suggest you also use a rhizomatous grass along with the crested <br />wheatgrass for seeding the topsoil stockpiles. Western wheatgrass <br />would work well for this. Please indicate what you will use for <br />seeding the topsoil stockpile and the rate at which the seed will be <br />spread. <br />Exhibit D - Reclamation Ptan <br />1. How will erosion of replaced topsoil be controlled if no mulch will <br />be used? The SCS soils information indicates that the hazard of <br />erosion is severe (the highest erosion rating possible) on the <br />Pinata - Rock outcrop complex which you have indicated on your map <br />to be the dominant soils group on the proposed permit area. We <br />suggest that you use two tons per acre of native grass hay or straw <br />spread and crimped into the replaced topsoil following seeding. <br />Please indicate your plans. <br />2. If seed is broadcast, the seeding rate you have supplied must be <br />doubled and the seedbed must be raked or harrowed to cover the <br />seed. Please indicate your plans. <br />3. Our calculations indicate that it would cost the State the amount <br />shown below to reclaim the site according to your reclamation plan: <br />a. Backfill of highwall to slopes of flatter <br />than 3H:1V (assumed: 1.1 15' highwall x 500' long <br />equals 6,250 cubic yards needed; 2.) maximum waste rock <br />push = 150') <br />6250 cu. yds. x 5.395/cu. yd .....................E2,468.75 <br />423 Centennial Building, 1313 Sherman Street Denver, Colorado 80203.2273 Tel.
