operator, for appearance of structural weakness and other hazazdous conditions. The
reports are retained at the mine site, and copies of the reports are submitted to the
Division in Exhibit lA of this Annual Report.

Colowyo is prepared for further discussion on the matter.
2. Colowyo requests the ability to pump stored water from A & B designated
ponds for general use specifically for dust control i.e. application to haul roads
within the permit area.
3. Colowyo requests the ability to facilitate one-time discharges to the surface
waters below the A ponds for the specific purpose of pond maintenance and
cleanout. Discharges would consist of short-term (24-48 hour) releases of
