Mr. Allen Sorenson - DMG <br /> December 11, 1996 <br /> Page 2 <br /> imately 25% of the total volume to eliminate ice along Highway 91. This water has <br /> therefore been incorporated into the snowpack. <br /> Climax believes that stream standards will not be exceeded as a result of this upset. <br /> Assuming that the frozen water from Highway 91 will melt in the spring over a 30 day <br /> period, and that the upstream contribution of unimpacted water is associated with an <br /> area of at least 3 square miles with an average annual snowpack exceeding 20 inches <br /> of water equivalent, the effective ratio of impacted water to fresh water is calculated to <br /> be 1:7441. <br /> The pipeline leading from 5-Shaft to the Climax water treatment system is under repair. <br /> To prevent reoccurrence of the upset, Climax has bermed the Storke Access Road to <br /> convey water off the road into a previously constructed French drain leading to the <br /> Storke Waste Water Pump Station. Plow operators have been notified that <br /> maintenance of this diversion during winter plowing operations is necessary to prevent <br /> the plowed road from becoming a conveyance structure. <br /> Should you have any question concerning the above discussion, please contact me at <br /> (719) 486-2150, ext. 723. <br /> Sincerely, <br /> Bryce R.
