iiiiiiiiiiiiiiiiiii <br />999 <br />STATE OF COLORADO <br />Roy Romer, Governor <br />DEPARTMENT OF NATURAL RESOURCES <br />MINED LAND RECLAMATION DIVISION <br />FRED R. BANTA, Director <br />DATE: September 26, 1989 <br />70: Carl Mount ~/ <br />FROM: Tim King /l <br />RE: Seneca II Annual Topography Map (Refer to Memo of August 9, 1989, <br />Same Title) <br />On September 19, 1989, I overlayed Exhibit 12-9A, "POStmine Contour Map" upon <br />drawing No. 0260-890260, "Annual Postmining Topography" to compare Peabody <br />Coal Company's approved postmine Contour to the actual postmine contour at the <br />Seneca II Mine. I noticed that the contours were only slightly similar. The <br />annual postmining map exhibited more diversity, with both steeper and flatter <br />slopes and much more undulating topography. <br />I then transposed the cross sections A-A' through F-F' from this annual map <br />onto the approved map. It appears that the 43.75 foot depression that is <br />indicated on cross section F-F' depicts a drainage where no drainage is <br />approved. I mentioned this depression in my memo of the same title of <br />August 9, 1989. This area is near the northern end of Auger Area E and shows <br />an area graded in 1988. As this topography is not approved, hopefully Peabody <br />plans to regrade this area much closer to the approved topography in the near <br />future. <br />Paragraphs 2, 3, 4, and 5 of the previous memo of August 9, 1989 remain <br />unchanged. <br />/bdc <br />9980E <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 80203-2273 Tel.
