CM0001327 <br />Findings of Fact, Conclusions of Law, Judgment and Decree <br />Case Nos. 92CW233 and 92CW336 - Page 53 <br />a. Net evaporation from tailing ponds and reservoirs in the <br />Tenmile Creek basin. The following calculation shall be used to determine net evaporation <br />from tailing ponds and reservoirs in the Tenmile Creek basin ("TP&R Net Evaporation"): <br />TP&R Net Evaporation = Total tailing ponds and reservoir water surface area <br />(in acres) x the applicable Monthly Net Evaporation <br />Rate contained in Table B below. <br />b. Net evaporation from wet beach and pool areas. The following <br />calculation shall be used to determine net evaporation from wet beach and pool areas ("WB&P <br />Net Evaporation'): <br />WB&P Net Evaporation = Total wet beach and shallow pool area (in acres) <br />attributable to tailing deposition x the applicable <br />Monthly Net Evaporation Rate contained in Table B <br />below. <br />TABLE B <br />Monthly Net Evaporation Rates <br />(acre-feet Der acre) <br /> Tailing Ponds <br />And Reservoirs Wet Beach and <br />Shallow Pool Areas <br />May 0.181 0.268 <br />June 0.266 0.375 <br />July 0.282 0.404 <br />August 0.175 0.268 <br />September 0.189 0.272 <br />October 0.118 0.176 <br />TOTALS 1.211 1.763 <br />C. Water trapped during milling and tailing deposition. The <br />following calculation shall be used to determine the volume of water trapped in tailing: <br />Tailing Trapped Water (in acre feet) = Tons of ore processed x 58.5 gallons <br />325,850 <br />r? <br />• <br /> <br />56642.
