Rimrock Exploration & Development, Inc. <br />J-Bird Uranium Mine/ DMO/ EPP Surface Water Quality Data <br />11.0 SURFACE WATER QUALITY DATA <br />Figure 1 illustrates regional hydrology in-relation to the Mine. There are historical <br />uranium mine sites within one mile of the J-Bird Mine. LaSal Creek is one-half mile and <br />the Dolores River is six miles from the Mine. No perennial water resources exist within <br />the projected disturbance area. Ephemeral drainages generally discharge toward LaSal <br />Creek. There are several dry washes and intermittent stream channels throughout the <br />disturbance area. Surface water flows only in response to significant precipitation events, <br />the majority of which occur during the summer monsoon season. Snowmelt may be a <br />contributing component to surface water flow. As previously mentioned in this section, <br />the SWMP has been developed with appropriate surface water controls to manage storm <br />events as defined by DRMS. BLM Uncompahgre Field Office completed an EA in <br />November 2006, prior to project start-up. Following is a table indicating the existing <br />surface water receiving stream standards. This table was copied from the BLM UFO EA, <br />2006. <br />Table 2- <br />('nlnrarln Ctra?m rho eai??nn+i r?.,o* <br />Stream Segment Stream Classification <br />LaSal Creek Aquatic Life Cold 1 <br /> Recreation 1 a <br /> Water Supply <br /> Agriculture <br />Dolores River Aquatic Life Warm 1 <br /> Recreation 1 a <br /> Agriculture <br />.,.... v,Viauv Lcyaruucui vi ruouc Wean ana t nvnonment, water tlualtty Control Commission, Reg. #35, <br />Classifications and Numeric Standards for Gunnison and Lower Dolores River Basins. <br />Within the Nov. 2006 EA, Affected Environment/ Environmental Consequences and <br />Mitigation Measures are addressed. Those components related to surface water are <br />identified below: <br />No Aquatic Habitats on the mine site or close enough to be impacted by activity <br />on the site. <br />• No Flood Plains <br />No Wetlands or Riparian Zones <br />• No Wild and Scenic Rivers <br />• No Wilderness Areas <br />• No Seeps or Springs Reported with-in 2.5 miles of project area <br />17
