I. Necessary controls shall be exercised during construction to <br />minimize erosion. <br />J. Where practical, waste minimization and pollution prevention <br />techniques will be employed. <br />K. H-G is a fully reclaimed minesite; and, therefore, no <br />materials of any kind are present at this site to pose any <br />threat of impact on waters of the State. <br />L. New areas previously not permitted are: Small Area Exemptions <br />(SAE'S) topsoil stockpile "B" (005), topsoil stockpile "C" <br />(006); and Sediment Pond Outslopes (007-010). <br />M. The following is a description of the controls and/or <br />procedures that address the goal of minimizing or eliminating <br />any pollution that may come from these areas. First and <br />foremost, H-G is governed by a Colorado Division of Mines and <br />Geology mining and reclamation permit which contains detailed <br />requirements to minimize adverse impacts to the hydrologic <br />system. Additionally, H-G is a fully reclaimed mine site that <br />is undergoing Bond release time frames. SAE's effectively <br />utilize vegetative cover and reclamation practices to produce <br />zero runoff hence zero sediment as demonstrated by SEDCAD <br />hydrologic modeling and actual field performance. Pond <br />outslopes effectively utilize vegetative cover to contain <br />runoff and sediment as demonstrated by actual field <br />performance verified by the required quarterly pond <br />inspections. <br />
