H. Transfer of Wells <br />No specific approvals granted. <br />I. Discharge of Water into an Underground Mine <br />No mining is proposed for the loadout facility. There will be no discharge of water <br />into an underground mine. <br />J. Stream Buffer Zones <br />1. The Division proposes to approve surface or underground mining activities <br />within 100 feet of a perennial stream. This decision is based on a finding that <br />the water quality and quantity shall not be adversely affected. The buffer zone <br />variance is granted for several areas located along Reed Wash and the Loma <br />Drain, both perennial streams (4.05.18(1)). <br />The discussion of stream buffer zones is located in Section 2.05.3(4)(d) of the <br />permit application. There are six sections of the proposed railroad loop that <br />will be located within 100 feet of Reed Wash and one section that will be <br />within 100 feet of the Loma Drain. The stream buffer zones of Reed Wash <br />and Loma Drain will be protected during rail construction with best <br />management practices and a bridge that spans Reed Wash. The Reed Wash <br />stream buffer zones will be protected during operations with the use of silt <br />fence and a sediment pond. Furthermore, the loading of the coal railcars will <br />be done by a batch weigh system, which will protect Reed Wash from <br />spillage. The Loma Drain stream buffer zone will be protected by silt fence <br />and a berm. <br />CAM prepared Sedcad hydrology demonstrations that show that the silt fence <br />protecting the stream buffer zones can treat runoff to NPDES standards for <br />settleable solids. The Sedcad demonstrations can be found in Exhibit 9 of the <br />permit application. <br />K. Probable Hydrologic Consequences <br />The operator's discussion of the Probable Hydrologic Consequences is presented in <br />Section 2.05.6(3)(b)(iii) of the permit application. Concerning surface water, CAM <br />presents their assessment that the waters of the Colorado River, Reed Wash and the <br />Loma Drain will not be adversely affected by operations at the Fruita Loadout. <br />Since the three sediment ponds are total containment ponds and the pond water will <br />be removed from the ponds and disposed of at an approved disposal facility, CAM <br />concluded that loadout operations will not adversely affect the surface water <br />regime and may even improve the water quality in Reed Wash. <br />27 <br />
