M-97-071 <br />Page 6 <br />(l) Although the application states that the operation is not expected to directly affect surface <br />or groundwater systems, this statement is probably not completely accurate given the <br />intermittent flow of water and apparent spring fed pools contained in the Peck Creek <br />tributary, and the fact that surface runoff from the disturbed areas will drain down this <br />tributary. Based on the vegetative characteristics of the channel bottom, it would appear <br />that the presence of water is not an aberration resulting from the unusually wet summer <br />and fall, but a fairly constant and reliable source of surface and spring fed water. <br />Therefore the application should: <br />(2) (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock <br />water ponds, reservoirs, and ditches of the affected ]ands and adjacent lands where <br />such structures may be affected by the proposed mining operations; <br />(b) Identify all known aquifers; <br />(c) Submit a brief statement or plan showing how runoff from disturbed areas will be <br />managed to protect against surface or groundwater pollution (such as <br />sedimentation) both during and after operation, including any designs as <br />appropriate for channel reconstruction or modification as necessary to safely <br />convey post-mining surface flows and preserve the hydrologic balance. One area <br />where this may become necessary is at the bridge where the Peck Creek tributary <br />crosses under Siloam Road and at the far north end of the permit boundary where <br />the channel transitions out of the mined azea onto undisturbed area. <br />The application states in Exhibit M, #'s 5 & 6, that there will be no discharge and <br />all storm water will be retained on site. Please identify how storm water will be <br />retained on site. If it involves retention structures, please identify what they will <br />be and where they will be located. The Division will need to approve any <br />designs associated with sediment control structures such as embankments, ponds, <br />etc. <br />(5) Please state whether or not a NPDES or storm water permit from the Water Quality <br />Control Division of the Colorado Department of Health has been applied for or acquired, <br />if necessary. The CDOH should be contacted to make this determination. <br />6.4.8 EXHIBIT H- Wildlife Information <br />While mining is occurring during the initial phases, the application's assertion that little impact <br />to wildlife will occur is probably accurate. However, the overall impact of the proposed plan <br />could have longer lasting effects based on how disrupted the water supply is along with a definite <br />change to the vegetative characteristics of the site. Therefore, a more through analyses of what <br />effects mining and reclaiming this site will have should be submitted. The analyses should <br />
