III IIIIIIIIIIIIIIII There is no sampling site upstream of the mine on Taylor Creek because the head of the Taylor Creek watershed wi~Tl be mined through by the Section 16 Pit. In addition to the monitoring discussed above, the operator is required to monitor discharges from all NPDES discharge points (sediment ponds) as required by the mine's NPDES permit. Results of this monitoring are reported to the Division and the Colorado Department of Health on a quarterly basis. Transfer of Wells No transfer of wells is proposed. All monitoring wells will be reclaimed prior to bond release (4.05.14). Discharge of Water into an Underground Mine No surface water will be discharged into underground mine workings (4.05.15). Stream Buffer Zones The Division proposes to approve surface or underground mining activities within 100 feet or through a perennial stream or stream with a biological community. This decision is based on a finding that the original stream channel will be restored, water quality and quantity shall not be adversely affected, and appropriate riparian vegetation will be reestablished. The buffer zone variance is granted for portions of Goodspring Creek near the sediment ponds which discharge into that creek and Taylor Creek near the loadout (4.05.18(1)). Probable Hydrologic Consequences A discussion of the probable hydrologic impacts of mining and reclamation operations is contained in pages 2.04.7-85 through 101 of the permit application. The original findings document (1982), an Amended Findings Document for Permit Renewal (1987), and Technical Revision No. 14 (1989) also include discussions of probable hydrologic consequences. Section 2.04.7 of the permit application and Section VI of the 1982 Findings Document contain extensive discussion of the hydrologic balance of the permit area. Potential Effects on Surface Water Quantity General Area Based on the hydrologic balance calculations for the drainages in the general area and the fact that all runoff from the mine area is to he either diverted around the mine or retained in sedimenta#° .~ ~^ _~g_
