The final issue with reparti to channel rundowns into the <br />mining area can best be solved •^ we discussed. 6ince the <br />mining operation will not require the construction of these <br />channel rundowns for •t least another 13 years, we would <br />agree to comply aL tfiis time with the UDFCD request that <br />they be designed to meet your criteria. 6ince technology fe <br />going to change over th• next 13 years and your criteria is <br />sure to change, it would be appropriate to wait and submit <br />designs based on current criteria Mhen they are needed. <br />We ara still interested in using concrete rubble to the maximum <br />degree possible. This material can possibly be used as subgrade <br />material Tor riprap. In addition, t think it is et 211 feasible <br />to use waste concrete where available to corntruct cutoff <br />trenches. These details would be submitted Tor review an <br />eorntruction was required. <br />Th• ~pro~ect will be covered by a reclamation bond and since this <br />is part of the reclamation, the .District should be adequately <br />protected, <br />This should address th• items of concern that we discussed. I <br />would appreciate your timely attention to this project. We are <br />scheduled for a hearing before the Board of Adjustment on June <br />30, 1968. t would tike to have your concurrence on our proposal <br />at least one week prior !o this meeting. <br />Please do not hesitate to call <br />eoncerrn. <br />Cordially, <br />Tt.iTT/~L//E~J APPL£OATE RINDAHL, INC. <br />Mike Applegate, P.E. <br />me if you have any questions or <br />I+IA lc r <br />Enca. <br />Ccr File MB7-120 <br />
