Box 225 <br />Florence, Colorado 81226 <br />Re: Diversion Ditch, "Dam D" Area <br />Our File No. C-037-81 - GEC STRIP MINE <br />Dear Mr. Chen: <br />Your plans to "shotcrete" the diversion channel between the unnamed ephemeral <br />drainage and the Magpie Creek diversion channel look good and we hope this <br />will eliminate the problem of contaminating undisturbed runoff. Although <br />your letter didn't mention it, I am presuming you managed to excavate the <br />rest of the channel to an appropriate and consistant grade. The other <br />problem we had discussed and noted was the need for an energy dissipation <br />structure at the juncture with the 14agpie Creek diversion ditch; please <br />submit these plans when they are available. <br />As always, feel free to call me if we can help. <br />Sincerely, <br />Peter H. Evans <br />Reclamation Specialist <br />PHE:mab <br />
