M. S. Hayes Page 4 June 29, 1990 25. The Operator still maintains there is no groundwater of any yield within the permit area. Obviously, a dry mine lends some validity to this position. The available drill hole data shows that no water was encountered in an,y of the drill holes over the mine permit area. Further, the mine permit area does not intersect any major drainages. The Operator submits that "additional study" is not warranted. I do not know how much information the Division has on the drill holes overlying the mine permit area. Please review your available information and let me know the information you lack. 26. The data collected for alluvial well AA-1 indicates the quality of the ground water on the west edge of the mine site has experienced some degradation since 1982. Potential pollutant sources include the coal stockpile immediately east of the well, the temporary gob pile which was also east of the well and the fact that the well is completed near the contact of the alluvium and mancos shale. The data does not show a consistent upward trend. The data collected during 1988 looks relatively good com- pared to that taken during 1987 and 1989. The Operator requests that this topic be s discussion of a future meeting. Additional analytical data will be available at that time. 27. The wells at the Bear No. 1 & No. 2 mines were actually sumps excavated in the alluvium. The "wells" Caere backfilled. The Operator does not believe that Rule 4.07 is applicable to this type of "well". 28. The Operator has not located its 1981 permit applica- tion so this item cannot be addressed. 29. The statistical summaries requested are presented on pages 2.04-30X, 2.04-30Y and 2.04-30Z. The requested graphs are presented on pages 2.04-30aa through 2.04-30gg. 30. A proposed cover standard is presented on page 4.15-3. 31. A noxious weed control plan was inserted in place of the pest and disease control plan on page 2.05-42. 32. Page 4.15.1 was revised to reflect the approved seed mix presented in Table 10. 33. Pages 2.04-43, 2.05-24R, 4.15-2, 4.15-3 and 4.15-4 were updated to reflect the actual acreage disturbed during construc- tion of the surface facilities at the Bear No. 3 Mine. Revised page 4.15-4 includes a discussion of the topsoil plan contained in Exhibit 23.
