_ - • J. If pes~:ible, •surfnr_c r~:atcr qualit.~r _;rmf,les should be obbrined above ar:d b~lo~; the aria affected by the mine ire Starf;rilin Gulch. This c.•ill indicate the m~igni~turle of any water 7uaLity r_han;es no:.• occurring at the mine. 9. Page SC of the application states that Stzrkville Gulch is intermittent in nature. Is this stream recharged bu ground water (alluvial or bedrock), or is it actually ephemeral in nature? 5. The applicant should c~iaz'acterize the foundation material anticipated to b.= e:<posed during the construction of thepsrmanentdiversion. r:'i1i this material ixa similar to that exposed by the original channel? If not, the new material should be_ analyzed to determine its physical earl r_henical properties. This information will identify acid, alkaline, or toxic characteristics as well as the durability of the divr_rsion. ^I. Nudrolooic lialance: Ground Water - 8ules 2.04.5, 2.04.7, 2.05.3(:), 2.05 and 9.05 Deficiencies: 2. The applicant needs to provide a discussion, along with appropriate maps ar;d cross-sections, which .identifies and characterizes all known local and regional aruifers which may be affected by the operation. The rationale by which conclusions .ire reached and the,names of Ure person(s) conducting the hydrologic investigations :=lrr,uld be included (Rule 2.03.3(4)). ~. For all aquifers identified in the affected area, the recharge, seoraye, and da charge characteristics should be described, in addition to the litholoyy, thickness and extent of water bearing units. 3. [rater quality information should ve provided for each aquifer potentially affected by the operation. 4. A spring and seep survey should be conducted within one mile of the nine affected area. The source and quality of tire water should be characterized. 4.4i ter quantity and yuality measurements should also be eh rained far all seeps, springs and wells identified within the affected area. 5. The uses of the ground water in the areas should be listed. Water yuality analysis should be obtained for alI wells in the area that may be affected by the opera ti.on. ~. Iraq water found in the mine now, or in the future, should he characterized r,•ith regard to Its source, quality, and quantity (rate of in flora). The applicant should attempt to predict the amount and quality of water anticipate-d to he encountered in the workings. VII, alluvial Vallrrl Floors - Ru1cs 2.OG.fi and 4.24 De fi c•i enci es: 1. The applicant muse provide a reconaissance level alluvial valley floor study for Raton Cx'eek. This study should include a map of unconsoli !la red alluvial deposits in the Raton Creok valley Chased on air photos and sampling), a discussion of the e.ristence of any vegetation along the alluvial valley indicat- .. my subi rri ya t.i on potential, a discussion of regional and his tnrlc uractic^~ :.i t~
