Hawkeye Mine Permit Number M- 1978 -311 concentrations that exceed the Water Quality Standards for the local Dolores River Segment number 1. 12.0 Water Quality Monitoring Plan Due to the ongoing prohibition of activity on DOE Lands monitoring wells have not been installed at the Hawkeye Mine location. Accordingly, a monitoring plan will be developed (if necessary) pending the outcome of the ongoing DOE PEIS process. As discussed in Section 8.0 above, the soil underlying the Hawkeye Mine site is mudstone and siltstone of the lower portion of the Salt Wash Member of the Morrison Formation and considered to be impermeable to migration of water into underlying rock units and groundwater. At the Ellison Mine site the ephemeral flow direction is to the southwest down the slope below the mine permit area and to the Dolores River. Prior to the resumption of mining activities, following lifting of activity prohibitions by the DOE, a surface water monitoring plan for the Dolores River will be implemented. 13.0 Climate Climate data from the nearest weather station is provided in Table 1 and Table 2. The nearest weather station is located at the C. J. Ranch, Summit Point, Utah approximately 6.5 miles southwest of Burros Mine. Table 1 Exhibit U -7
