Discharge of water to underground workings will not occur. <br />Stream Buffer Zones <br />1. The Division has approved surface and underground mining activities <br />within 100 feet or through perennial streams. This decision was based <br />on a finding that on Hubbard Creek the original stream channel will <br />be restored, water quality and quantity shall not be adversely affected, <br />and appropriate riparian vegetation will be reestablished. On the <br />North Fork of the Gunnison, the decision was based on the fact that <br />the original stream channel would not be affected and water quality <br />and quantity would not be adversely affected. The buffer zone <br />variance was granted for the areas located at the stream crossing and <br />pre-law bench area at the lower Hubbard Creek site and the topsoil <br />stockpile at the upper Hubbard Creek site. The buffer zone variances <br />on the North Fork of the Gunnison are located at the alluvial well and <br />leach fields just above and below the town of Somerset (4,05.18(1)). <br />Sanborn Croek Minc <br />16 <br />Petmit Revision No. 3 <br />
