Mr. Edward L. Bischoff <br />Page 4 <br />July 16, 1987 <br />defined the baseline conditions which exist in this area prior to storing <br />any decanted mill water in the Hazel A. adit. <br />3. During the Iasi four days, Gold Hill Ventures has completed the <br />excavation of the permanent diversion ditch that will be used to protect <br />the tailings pond from water runoff from the precipitation catchment <br />area above the tailings impoundment structure. This water runoff diver- <br />sion ditch was constructed according to the design submitted to Gold Hill <br />Ventures by Ted Zorich and Associates, Inc., of Englewood, Colorado. <br />I am attaching construction certifications by qualified profes- <br />sionals associated with the Denver Engineering Corporation of Golden, <br />Colorado, for the tailings impoundment structure, the installation of the <br />geomembrane liner, and the bulkhead in the Hazel A. edit. The construc- <br />tion certification of Mr. Ted Zorich for the water runoff diversion ditch <br />is also attached to this letter. <br />Since your site inspection with Mr. David Berry on April 28, 1987, <br />Gold Hill Ventures has made considerable progress in cleaning up and <br />restoring the area surrounding the millsite that was disturbed during the <br />construction of our facility. In addition, a berm has been built along the <br />downstream perimeter of the tailings embankment dam, and rocks are <br />being used to prevent further gully erosion resulting from bench level <br />water runoff. <br />If you or your staff have any questions or suggestions regarding <br />the contents of this letter and attachments, please contact me at the <br />Gold Hill Mill or my office in Longmont. <br />Sincerely, <br />.~. ,8~~ <br />Mark A.
