Dear Mr.Menzer:
On July 15, 2004 the Division of Minerals and Geology(DMG) issued conditional approval of the Technical Revision

Dam Tailing Impoundment at the Henderson Mill.
The following conditions are applied to the approval of technical revision TR-015.
STIPULATION NO.01:
:,. Disposal of Urad Treatment Plant sludge into the Henderson Tailing Impoundment is not being approved as a
post mining land use. Once the time arrives that the area of the impoundment being used for sludge disposal is to
be reclaimed under the terms of the approved reclamation plan and the rules and regulations of the Colorado
Mined Land Reclamation Board, sludge disposal into the impoundment must be discontinued.
The terms of the Technical Revision No.015 approved by the DMG are hereby incorporated into Permit No.M-1977-
342. All other conditions and requirements of Permit No.M-1977-342 remain in full force and effect. DMG's approval

If you have any questions,please contact me at 303l866-4063 or at [e-mail].
Sincerely,
