located on the inside of the Upper Bench Road and Bench to a pour-off (DP2) into Area <br />7. <br />Area 4 and Area 14: <br />Area 4 is a moderately vegetated upper slope area immediately above Area 14, the <br />southern portion of the Upper Bench Road. A highwall sepazates Area 4 from Area 14. <br />The combined runoff from Areas 4 and 14 will be conveyed by drainage channel DS4 <br />located on the inside of the Upper Bench Road to the Reseazch Mine area, where it <br />discharges to the natural drainage by way of discharge structure DP3 located immediately <br />south of the former Research Mine portal. Depending on depth to bedrock, DS4 may <br />include all or portions of the Upper Bench Road. <br />Area 5: <br />Area 5 consists of the natural subbasin located above the Research Mine, and main mine <br />access road. This area is mostly naturally vegetated but also contains Logan Wash Road <br />(the primary access route for ranchers and gas industry operations) and a reclaimed area <br />that was part of past mine operations. The reclaimed area contains a small stock <br />detention pond located near the elevation of 8,280 feet (above mean sea level). Runoff <br />from this azea will be conveyed by the natural drainage channel that exists. That portion <br />of the drainage that crosses the main mine access road and Research Mine Bench will be <br />recontoured to contain the design flow from this subbasin to the downstream portion of <br />the natural drainage below the Reseazch Mine dump. The conveyance channel on the <br />road and bench is designated DSS and the discharge point on the face of the dump is <br />designated DP3. <br />Area 6 and Area 15: <br />Area 6 is the steep, forested, west-facing slope opposite the Research Mine portal area. <br />Area 15 is the small portion of mine access road at the toe of Area 6. The combined <br />runoff from Areas 6 and 15 will be conveyed by drainage channel (toe ditch) DS6 located <br />on the inside boundary of the mine access road. The ditch will convey water northward <br />to the recontoured natural drainage DS4 associated with Area 5, and ultimately discharge <br />at DP3. <br />Area 7 and Area 10: <br />Area 7 is the steep sparsely vegetated terrain that is situated between the Upper Bench <br />Road and the Lower Bench Road. Area 7 also receives runoff from discharge points DP1 <br />and DP2. Area 10 is the Lower Bench Road. Runoff from Area 7 and 10 will be <br />managed by an open channel on the inside of the Lower Bench Road and a drainage <br />channel constructed on the east boundary (at the toe of the Upper Dump) of the Lower <br />Bench. These drainage structures are collectively designated DS7. DS7 will convey <br />water north to the end of the northern limit of the Lower Bench where water will be <br />dischazged at discharge point DP4 to the natural drainage ("Dry Gulch"), located <br />approximately 100 feet to the north. <br />Western Water & Land Inc. <br />
