The application for a Reclamation Permit for this operation was deemed adequate for technical review on March
8, 2000. The Division reviewed the application and sent you an adequacy review. Your response has been
reviewed and some clarifications to your application are still needed before i[ can be approved for permit
issuance. Cheyenne county continued the Division consideration date to April 21, 2000 t allow more time to

fully respond to this letter, please contact me requesting continuance of consideration to a later date.
Please be advised that your application may be deemed inadequate, and your application may be denied April
2l, 2000 unless the following adequacy review items are addressed to the satisfaction of the Division.

Rule 6.3.3(F) requires that you specify the dimensions of the pit excavation. Part of your response was -
"Dimensions of the pit excavation will be approximately 200 x 200 feet and you show a pit [hat size on your
revised mining plan map. After a phone conversation with you it is clear that you intend to only conduct
extraction operations in an area of 200 x 200 feet at any time and that the remainder of the area to be mined
will either be in a stage of reclaration or unmined. Please clarify this mining/reclamation sequence in your
exhibit C.
Also, you stated that "Operator will say 125 feet from high-water line". Please show on the Mining Plan
Map the high-water line and a line indicating the limit of extraction adjacent to Ladder Creek.
4. Under your description of measures to minimize disturbance to the hydrologic balance (Rule 6.3.3(1)... you
simply staled "New Exhibit E Map". Your new map does not show any features that would prevent
sedimentation of Ladder Creek.
Please describe how you plan to prevent surface flows across the mine area (stormwater runnoFf) from
carrying sediment to Ladder Creek. If the pit floor does not daylight on the creek side and the pit is deep
enough to retain overland flow and on-site precipitation from a significant storm even[, [hen describe [his

the maps the features such as a sediment trap. diversion, etc. you will construct to prevent sedimentation of
