Discharge of Water into an Underground Mine Discharge of water to underground workings will not occur. Stream Buffer Zones The Division has approved surface and underground mining activities within 100 feet or through perennial streams. This decision was based on a finding that on Hubbard Creek the original stream channel will be restored, water quality and quantity shall not be adversely affected, and appropriate riparian vegetation will be reestablished. On the North Fork of the Gunnison, the decision was based on the fact that the original stream channel would not be affected and water quality and quantity would not be adversely affected. The buffer zone variance was granted for the areas located at the stream crossing and pre-law bench area at the lower Hubbard Creek site and the topsoil stockpile at the upper Hubbard Creek site. The buffer zone variances on the North Fork of the Gunnison are located at the alluvial well and leach fields just above and below the town of Somerset (4.05.18(1)).
