November 19, 2007 Kerr Coal Company P.O. Box 459 Florence,Co 81226 Marr Mine Surety Release Oversight Inspection Permit#C-80-006 October 23, 2007 Weather and Ground Conditions: Clear Skies The Mine received snow on October 21 Two to four inches-of patchy snow was still on ground-throughout the site, with only patchy snow at the load out. Personnel present during the Inspection: Janet Binns, Colorado Division of Reclamation,Mining and Safety(DRMS),Denver Kelly Hodgson,U.S. Bureau of Land Management(BLM),Kremmling Office George Patterson,Kerr Coal Company Bob Peterson,North West Colorado Consultants Elizabeth Shaeffer, Office of Surface Mining(OSM),Denver Field Division GENERAL COMMENTS I participated in a bond release inspection of the Man Strip Mine October 23,2007. Kerr Coal Company requested Phase I and 11 bond release on portions of the Marr Mine and Load out,and Phase III bond release on 381.7 acres comprised of Pit 1,Pit 720,and Man Pit. Stop 1-Load Out Site and Shop Building The access road to the load out was in fair condition. During the inspection, a motor grader cleaned sediment off the access road. The vegetation in the load out area is in good condition,and the area has good shrub cover. There was no visual evidence of erosion or bare areas through the patchy snow ground cover.We walked around the sediment pond on the irrigation ditch. The pond was discharging clear water(staff gauge at weir read .002). The shop building that remains is an approved permanent structure. Stop 2-Pit 1 After parking on County Road 12E, we walked Pit 1 along the PD3 drainage toward the south.Additional rock was added to the northern end of PD3 immediately east of CR 12E.Vegetative cover in Pit 1 appeared fine. One area of concern in the south west area of Pit 1 had active rill formation. Several of these rills continued through the contour furrows and measured 4-8 inches deep and were from 10—40 feet long. Janet Binns used a Trimble unit to take a GPS location to map the rilled area. She notified the group that this area of concern appeared to coincide with the 2.4 acre area eliminated for the June 2001 SL2 Phase II proposed decision by DRMS.
