Therefore, Western Slope Carbon requests that the CMLRD <br />modify the monitoring and reporting requirements at the mine until <br />such time that operations may resume. <br />The proposed monitoring and reporting frequencies are as follows: <br />Monitoring <br />• Springs 8 through 11 will be checked monthly, May through <br />October, for flow, pH, conductivity and temperature. <br />• The Norris Alluvial Well will be checked monthly for flaw, <br />pH, conductivity and temperature. <br />• A complete chemistry will be taken on the Norris Alluvial Well <br />twice per year (May and October). <br />Reporting <br />• The first report will cover January through June and will <br />consist of the monthly spring and Norris Well monitoring data <br />and a complete chemistry report for the Norris Well. <br />• The second report will cover July through December and will <br />include the same information as the first report; it will also <br />summarize data for the entire year and be used as the Annual <br />Hydrologic Report. <br />A SUBSIDIARY OF NORTHWEST ENERGY COMPANY <br />395 GMIPETA WAY SALT IAKE CT'.
