iii iiiiiiiiiiiu iii <br />The Corley Company <br />Pnone 6325050 PO. Box 1821 <br />Nov. 30, 1993 <br />COLORADO SPRINGS, COLORADO 80901 <br />RF~F.~, , <br />Ms. Erica S. Crosby r <br />Division of Minerals & Geology <br />1313 Sherman St, EC ~8 19 <br />Denver CO 80203 n'~•%~ 93 <br />..,Ir~,~~. 4 <br />Dear Ms. Crosby: 4,,~:`n <br />This is a response to your Nov. 24, 1993, letter. <br />We believe that the Division was the party responsible for correctly <br />estimating. the cost for the Iarrison Western liability. We have asked <br />several times how the amount of $18,500 was calculated, and Mr. Routten <br />told us that Ms. Begej arrived at that amount with no records remaining <br />that explain how she actually miscalculated. We would like to point out <br />that the first design work that we are aware is dated July 7, 1993, <br />which is long after Harrison Western was released. How could the <br />$18,500 amount be estimated without a design? <br />We also have stated that we believe the Division should be liable for <br />the costs of the Harrison Western liability in excess of the $18,500; we <br />do not think that the GEC bond money should be used for this work. This <br />statement applies to either the original design or the new alternate <br />design, In the event that the Division decides to revert to the <br />original design, it is important to note that the original design is <br />flawed by utilizing 2.6 in. rain for a 10 year 24 hour event and using <br />that event instead of a 100 year event for a permanent structure. Mr. <br />Berry has been emphatic that the 100 year event must be used for such <br />designs. <br />Finally, we have not had a reply to our question dated Nov, 16, 1993: is <br />a licensed PE required for design of permanent water diversion <br />structures in Colorado? <br />Sincerely, <br />(/" <br />W.D. Corley, J . <br />President <br />
