J. J. Dudash - 2 - November 15. 2002 <br />13. The discussion of current status of the mine was updated on page 2.05-i through 2.05-ii. <br />I was unable to prepare a brief discussion of subsidence monitoring. According to UTE <br />Engineering, they performed subsidence monitoring during 1997. I do not have a copy <br />of this 1997 data. Does the DMG have a copy? Enclosed are three amended pages <br />from Exhibit 22 which make some changes in the subsidence monitoring plan. <br />14. The Protection of the Hydrologic Balance section of the permit was updated regarding <br />the Edwards portal slide and the Operator's current understanding of the spring. <br />Enclosed are amended pages 2.05-55a through 2.05-55c. <br />15. A discussion of the Edwards portal spring discharge was added to amended page 2.04- <br />29b. <br />16. See item 3. above. According to discussions with past employees of Bear Coal <br />Company, the pond was constructed in an area that was previously disturbed so no <br />topsoil was salvaged. <br />17. The list of monitoring requirements on pages 2.04-30 and 2.04-30b were updated. The <br />requirement to monitor Lone Pine Gulch and the springs in Lone Pine Gulch was <br />deleted. Over seven years of monitoring data collected for the annual hydrologic reports <br />has shown the mine has not had a noticeable affect on the gulch or springs. August <br />sampling of the North Fork of the Gunnison River was added to the monitoring plan. <br />A summary of the Lone Pine Gulch springs are included as new pages 2.04-30iii <br />through 2.04-30vi. <br />18. The DMG will be notified as soon as Bear's NPDES permit is issued. <br />19. The current status of reclamation was updated on permit application page 2.05-i. <br />20. There an no exploration or other bore holes that reed to be reclaimed other than alluvial <br />monitoring wells AA-1 and AA-3. <br />21. No comment required. <br />22. No comment required. <br />23.
