resources describing the groundwater quality setting other than broad information from <br />the CDWR indicating that the area as a whole was not defined as being an aquifer due to <br />the lack of potable supply characteristics (quantity and quality). The Ruby Trust has held <br />a Colorado Discharge. Permit System (CDPS) permit for their point source discharge since <br />May 25, 2007 (CO 0037206). The data obtained from the discharge is a direct reflection <br />of the groundwater quality since the discharge originates from the underground water <br />collection point(s) within the mine. A summary of the CDPS sample analysis results is <br />provided in Table 6.2. Results indicate that the groundwater is of good quality; contains <br />a slightly basic character and contains natural levels of certain metals. <br />Surface water Resources: <br />The mine site occurs immediately adjacent to Sneffels Creek which is a tributary to <br />Canyon Creek which in-turn is a tributary to the Uncompahgre River. The segment <br />adjacent to the Ruby Trust is not a stream segment defined by the CDPHE WQCC as <br />having a designated use, however it drains into 'Segment 9' of the Uncompahgre River <br />Basin which has defined uses of 'Aquatic life Cold 2, Recreation P and Agriculture'. The <br />applicable WQCC standards protective of these uses are provided in Table B.1 <br />summarized from CDPHE WQCC, 2007). <br />Sneffels Creek headwaters originate just above the Ruby Trust Mine within the Yankee <br />Boy and Governor Basins. Flows are year-round and subject to the influences of snow <br />melt and rain fall. Water quality within the head-basin areas has been characterized as <br />part of area studies. Results from locations at headwaters of Sneffels Creek are <br />summarized in Table 6.3. There are seasonal results for one of the locations <br />summarized in Table B.3 that were taken from 2007 and 2008 (source: The Mining <br />Company - as part of N01 quarterly studies for The Mountain Top and The Liberty). <br />These seasonal results are provided in Table B.4. Results indicate that Sneffels Creek is <br />of good quality and contains natural levels of certain metals that exceed certain surface <br />water standards. <br />d) Wildlife Statement= already provided within EXHIBIT D of the 'Walker Mining and Milling Inc., <br />1979: the Original 'Limited Impact (110) Permit Application Form (received September 24, <br />1979: File No. 79-1811UG/HR) and a letter provided by Ken Miller dated November 20, 1979 in <br />response to the DRMS adequacy review of the original permit application. <br />References Cited <br />Burbank, W.S. and R.G.
