III. COMMENTS-COMPLIANCE
Below aye comments on the inspection. The comments include discussion of observations made during the inspection. Comments also

This was a Partial inspection conducted by Janet Binns of CDRMS. The mine no longer extracts coal,but the remaining
surface pit(Pit B)is permitted to dispose of flyash. CEC caps,regrades,topsoils,mulches and seeds the pit as the ash fill
progresses. The weather was hazy and warm,with high light clouds. The mine site is dry,with CEC's records showing the
only precipitation recorded in September was 0.32"on 9/12/2009.
Records: The Division requested,and CEC provided a copy of the USR#1160 issued by Weld County Department of
Health and Environment-Solid Waste Division.
Roads: The haul road to the pit and return to the facilities were dry and well graded. Road side ditches are well graded and
shaped. One ash truck was on site during the inspection. The operator said that they are currently hauling 5 truckloads of ash
per day. The haul road and access road are in good condition with no concerns and no noxious weeds along the roadsides.
Hydrologic Balance: The mine site was dry with both ponds; pond 2,and dugout pond dry. The puddles in Pit B have dried
up as well.
Backfill: CEC is placing ash on the upper lift of Pit B,north of the Area 31 R reclamation area. CEC was using a grader to
spread out ash that had been recently dumped. No blowing of the ash or spoil cover was observed. No problems were noted
with the ash placement and spreading.
Revel etation and Reclamation Success: Sorghum seeded in Area 31R is very short,--6"high,and is drying up. CEC will
seed the permanent seed mix into this sorghum cover crop this fall. CEC received their permanent seed on 9/16/2007.
Reclaimed area 30 has established a healthy stable perennial vegetation stand. Species noted during the walk through that
are well established include; indian ricegrass, buffalo grass, slender wheatgrass, switchgrass,prairie coneflower, side-oats
grama grass,Little bluestem, Sand bluestem,and well established prickly pear.
CEC mowed Reclaimed area 25 in an effort to knock down the annual species seeds
CEC changed the reclamation success standards previously from reference areas to a formula standard. CEC plans to
submit a revision to the permit to eliminate the maintenance of the reference areas from the permit.
