There is no evidence of acid or toxic forming material at <br />this site. <br />F. Impoundments <br />Refer to Section D. Sedimentation Ponds, above. <br />G. Surface and Ground Water Monitoring <br />1. The applicant will conduct monitoring of ground water in a <br />manner approved by the Division. The ground water monitoring <br />plan is specified on Page 2.04-46i of the permit document <br />(4.05.1311)1. <br />2. The applicant will conduct monitoring of surface water in a <br />manner approved by the Division. The monitoring plan was <br />submitted under 2.05.6(3)(b)liv) and as specified on page <br />2.04-46i of the permit document. (4.05.13(2)). <br />I. Discharge of Water into an Underground Mine <br />Discharge of water to underground workings will not occur. <br />J. Stream Buffer Zones <br />1. The Division has approved surface and underground mining <br />activities within 100 feet or through perennial streams. <br />This decision was based on a finding that on Hubbard Creek <br />the original stream channel will be restored, water quality <br />and quantity shall not be adversely affected, and appropriate <br />riparian vegetation will be reestablished. On the North Fork <br />of the Gunnison the decision was based on the fact that the <br />original stream channel would not be affected and water <br />quality and quantity would not be adversely affected. The <br />buffer zone variance was granted for the areas located at the <br />stream crossing and pre-law bench area at the lower Hubbard <br />Creek site and the topsoil stockpile at the upper Hubbard <br />Creek site. The buffer zone variances on the North Fork of <br />the Gunnison are located at the alluvial well and leach <br />fields just above and below the town of Somerset <br />14.05.1811)1. <br />K. Probable Hydrologic Consequences of Mining 12.05.613)(b)liii)) <br />This section reviews the Probable Hydrologic Consequences (PHC) of <br />mining at the Somerset Mine location. The review includes the <br />probable consequences which will result from the entire Somerset <br />Mine, including the Sanborn Creek Mine, which was approved with <br />Permit Revision Number 1. The Cumulative Hydrologic Impact Study <br />(CH IS) for the North Fork of the Gunnison River, contains a <br />detailed analysis of the cumulative impacts of all currently <br />-14- <br />
