<br />Page 3 <br />rir. Gordon Hayes <br />January 29, 1980 <br />2. Amore detnilad description of the seepage cheek dam and cha sediment <br />pond it impovada is needed. Ie this the entire control method for erosion <br />and runoff from the mining operation ~•to Deer Creek? <br />3. There should be no diechar = of water from the mining operation. If there <br />is, there may ba a necessity for an 2JPDE5 permit. <br />4. The seeps on thn quarry aitn should be described more thoroughly. <br />Exhibit R: <br />1. Asite-specific wildlife evaluation ie needed. This should include the <br />species commonly found on the site, potential impacts to endangered species <br />(if any) and the expected overall impact on wildlife due to the quarrying <br />operation. <br />3. The local wildlife conservation officer may be of help in this C-'=°rd. The <br />negative letter of January 19, 1977 from the Divieicn of ~111dlife is mt <br />helpful in this matter. <br />Cxhibit I: <br />1. Row much topsoil of the steep-slope type described is available for recla- <br />mation? Sdhere is it being stockpiled? <br />2. If theta .s not enough topsoil available for planned reclamation, t5e sub- <br />stitute (e.g., overburden or fines) should be carefully analysed as a <br />potential growth ~+edim. <br />Fachibit J: <br />See page 20 in the Rules and Regulations for the site-specific vegetation infor- <br />mation needed for this exhibit. Once again, the Soil Conservation Service or <br />the Colorado State Po rest Service may be of assistance is this matter. <br />Exhibit L: <br />1. If only 20 of the 75 permitted acres are to be disturbed by the quarr~~~ g <br />operation, then only these 20 acres need to be bonded. In this case, the <br />$34,100 reclamation costs given would be an adequate bond amount. <br />2. If, however, all 75 acres are to be disturbed to some extent (and thus krill <br />need reclamation), you may wish to onsider defining areas mayor noderate <br />and ciinor disturbance within the 75 total acres (or a subsection thereof) <br />and bond each area accordingly (with a floating or non-floating bond). <br />
