. <br />Mr. Dale Larsen - 2 - June 18, 1985 <br />5. The Division may propose that no pillars be extracted in areas with <br />less then 300 feet of overburden to prevent subsidence in ephemeral <br />drainages. The applicant may wish to address this relative to mine <br />inflow and poor quality discharge. <br />6. The Division requests that Peerless Resources monitor the Victory No. 3 <br />discharge by welding a stand pipe or other mechanism on to existing <br />pipe in order to assess the quantity and quality of the Victory No. 3 <br />discharge and to isolate this discharge from actual and potential <br />discharges by the Coal Gulch Mine. <br />7. The applicant should estimate maximum flows to the sediment pond. The <br />disturbed area drainage, Arness/McGriffin portal discharge and Coal <br />Gulch portal discharge (worst case estimate) should all be included. <br />The sediment pond should be resized to accommodate this inflow. <br />8. As discussed with Mr. Strid and Mr. Czarnowsky, the existing sediment <br />pond at the site appears to be conducting water through the bottom or <br />embankment of the pond as evidenced by a drop in pond water level, <br />though inflows are greater than discharge. The Division requests a <br />discussion of where the water is going and how Peerless Resources plans <br />to contain this water. <br />9.

The application should provide the Division with a subsidence <br />monitoring plan above all drainages, specifically to the northwest of <br />the facilities area and in the area to be mined. In the monitoring, <br />the applicant should address the amount of movement, the location of <br />movement and the amount of inflow which is then depleted by movement <br />into the fracturing. <br />11. The Division requests that Peerless Resources drill a double completion <br />well in the NWl/4 NWl/4 Section 16, T35N, R10W. The purpose of this <br />well will be to monitor quantity and quality of water in the Lower <br />Cliff House Sandstone, and the Upper Menefee Formation. This well <br />should be completed in such a manner so as to preclude any connection <br />between formations through the wells. Pump or slug test results, water <br />quality data', drillers logs, and completion information should be <br />submitted to the Division <br />12. The Division would like peerless to submit pertinent information <br />concerning the proposed water supply well upon completion. This <br />information shall include state engineer number, depth of hole, <br />drillers log, completion information, production data, and water <br />quality analysis. <br />
