Koehler <br />Cyprus Orchard Valley Mine <br />P.O. Box 1299 <br />Paonia, Colorado 81428 <br />Telephone (303) 279-7982 <br />(800) 544-5528 <br />Facsimile (303) 279-7988 <br />Subject: Water Rights and Surface Hydrologic Investigations (October, 1992) <br />Simon Hydro-Search Project No: 204792018 <br />Dear Mr. Koehler: <br />Cyprus Yampa Valley Coal Corporation (Cyprus) contracted Simon Hydro-Seazch to perform a field <br />verification of surface water features in support of an expansion permit application for the Orchard Valley <br />Mine. Prior to initializing the monitoring program, Simon Hydro-Search, in concurrence with Cyprus, <br />selected key surface water features (i.e., ponds, drainages and springs) for inclusion in the monitoring <br />program. The surface features are located in Sections 10, ] 1, and 15, T13S, R92W and are shown on <br />Figure I (Attachment 1). The surface water features were named using the section number in which they <br />occurred (e.g., Pond 10-11 and Drainage IOD-12 occur in Section 10), unless they were previously <br />named. <br />Summary of Surface Water Features and Water Quality Data <br />The site has been monitored four times by Simon Hydro-Search; October 1991, April 1992, June 1992 <br />and September 1992. During the first and second visits, all of the main drainages were physically walked <br />by a Simon Hydro-Search hydrogeologist in the field, for the purpose of identifying and verifying all <br />observable surface water features. The following tasks were performed during each of the four visits: <br />Physical description of all observable surface water features (streams, springs, and <br />ponds), along with a description of the location, size, and whether the features are natural <br />or man-made; <br />Measurement of pH, temperature, specific conductivity and dischazge in each surface <br />water drainage, if sufficient Flow was present; and <br />Surface water sampling in each surface water drainage with observed flow; samples were <br />collected and submitted to a representative of Cyprus for subsequent analysis. <br /> <br />simon <br />ICf'dEnvilonmenla! <br />
