Ungefug <br />Southway Construction Co., Inc. <br />117 White Pine Drive <br />Alamosa, CO 81101 <br />RE: Filmore Pit Application and Adequacy: File No. M 90-144 <br />Dear Mr. Ungefug: <br />The Division has completed its adequacy review of your Filmore Pit <br />application. Our remaining questions and comments follow: <br />Exhibit D - Mining Plan <br />OF'~~( <br />/~~'~ OR9 <br />~~~ to <br />~. n.~ <br />~~ <br />rH'!0 ~ <br />Roy Romer, <br />Governor <br />Fretl R. Banta. <br />Division Director <br />You plan to stabilize the topsoil stockpiles with Crested Wheatgrass at a rate <br />of five Founds per acre. Crested wheatgrass is a bunch grass which is not as <br />good for soil stabilization as sod-forming grasses are. We recommend using <br />the foll~~wing mixture, the rates per acre will result in approximately SO <br />seeds per 5 ft2 which is the recommended rate for broadcast seeding. <br />Western wheatgrass 12 Pounds/acre <br />Thi~:kspike wheatgrass 10 Pounds/acre <br />Alf,~lfa (Ladak) 2 Pounds/acre <br />Total ~4 Pounds/acre <br />Exhibit E - Reclamation Plan <br />The reclamation plan map shows a "day lighting" to the existing shape on the <br />East side of the pit. There is a drainage and spring adjacent to this side of <br />the disturbed area. Will the day lighting allow runoff from the disturbed <br />area to enter the drainage/wetland? If so what measures will be taken to <br />prevent sediment from entering the offsite wetland and drainage? <br />Exhibit H -Wildlife Information <br />This exhibit states that "as per the Division of Wildlifes' recommendation we <br />will not disturb the wetlands area on the East end of the leased area, a <br />buffer zone of at least 100 feet will be maintained ---". The attached <br />comments from the Division of Wildlife recommends a 100 to 200 yard buffer <br />zone. Why was a distance of only 100 feet proposed? Also, how will this <br />buffer zone be maintained to prevent disturbance by mining equipment and/or <br />other related traffic? <br />C <br />STATE OF COLORADO <br />
