J. E. STOVER & ASSOCIATES <br />2768 COMPASS DRIVE, SUITE 101 <br />GRAND JUNCTION, COLORADO 81506 <br />PHONE: (970) 245-4101, FAX 242-7908 <br />MINE ENGINEERING <br />MINE RECLAMATION <br />November 12, 2004 <br />CIVIL ENGINEERING <br />CONST. MANAGEMENT <br />J.J. Dudash RECEIVED <br />Division of Minerals & Geology <br />1313 Sherman St., Room 215 NOV 1 5 2~J04 <br />Denver, CO 80203 <br />Oirision ~f Minerals and Geology <br />-- Re-Bewie Ne-2-Mine - -- ------ ----- - _--_ _ _ _ _ ___ - - - - - - -- <br />Pond F <br />Permit C-96-083 <br />Dear Mr. Dudash: <br />The DMG's letter dated September 1, 2004 noted differences in the approved design of <br />Pond F and the as-built construction of Pond F. The differences were in the <br />construction of the primary and emergency spillways. <br />After receipt of the DMG's letter, the construction of the emergency spillway was <br />changed so it conforms to the approved design with the exception that the Deer Trail <br />Ditch culvert is partially exposed in the spillway. The Deer Trail Ditch culvert will not <br />impeded the capacity of the emergency spillway nor will it handle the maximum design <br />flow in the spillway. <br />The Operator is currently working with the DMG and the Bureau of Reclamation (BOR) <br />to change the emergency spillway so it does not flow into the Fire Mountain Canal. The <br />Operator believes the emergency spillway's channel can be extended over the nearby <br />down gradient rail bridge and thus overshoot the Fire Mountain Canal. <br />The Operator has been in contact with the BOR to determine details of the rail bridge's <br />right-of-way to determine if it can be used as an overshot. As soon as theses details <br />are know, the Operator wiH re-design the emergency spillway. <br />Sincerely, <br />~ /~y' <br />J. E.. Stover, P.E. <br />Consulting Engineer <br />
