Keenesbur~ Mine, Feb.10, 2005, pQ.2
We inspected all disturbed areas, currently active coal combustion by-product (CCB-coal power plant,
mixed bottom ash and fly ash) disposal pit, reclamation areas, spoil cover material area, topsand storage
stockpiles, surface water runoff control, and groundwater, spoilwater, and ash monitoring well locations.
There is no federal coal or federal surface lands involved on or adjacent to this mine. We made stops and
observations, or photos, including but not limited to the following: Dugout pond and sediment pond # 2.
As noted above this is a zero discharge facility. There is an approved pumping plan in the unlikely event
sediment pond 2 were to fill to discharge leevation. The discharge could be prevented by pumping from
sed. pond 2 into the Dugout pond.
Long term spoil storage area was noted. Current CCB disposal is in Pit B and the permit discusses
proposed CCB disposal through 2,010. Pit B has been initially backfilled with spoil material approx. 40'
up from the bottom of coal seam removal to approx. 5' above the projected ground water table surface.
Then 3' of clay material liner caps the initial spoil backfill before CCB disposal. The CCB material is
placed in 2 staggered lifts, and the ongoing CCB placement is periodically (weekly-semi weekly-or as
needed) sealed against the wind with 5"-6" of spoil material. After the second CCB lift is completed
(approx. total 30' to 35' thickness for both lifts combined) final backfilling and grading to the
approximate original contour is accomplished with a 6' spoil lift over the completed CCB placement,
and a final 2' topsand-plant growth medium to finish. Pit A-CCB disposal has been completed and Pit A
is reclaimed and awaiting additional bond release. A 1998 Phase I (153 acres) and Phase II (4l acres)
bond release (bond release application SL-1) has been approved by DMG in the Pit A area
AMW-1 monitoring well was observed. SMW-2 monitoring well was observed. AMW-2 monitoring
well was observed in the Pit A area. Reclaimed areas here are stable with little evidence of erosion.
Perennial grasses are becoming established on the older reclamation areas. We observed the topsand
storage areas. The facilities area and associated work-storage areas are neat and orderly with no
problems noted. We drove to the Osgood sand reference area. Signs and markers are in place where
required. This concluded the field inspection.
Mr. Kaldenbach conducted a thorough review of permitting and required environmental records
including but not limited to the following: Current DMG mining permit, which expires 11/3/2006;
current documentation of Travelers Casualty bond in the amount of $ 2,614,909; February 26, 2004,
Annual Reclamation and Annual Hydrology Report (AHR)-the AHR documents the required quarterly
ground water monitoring from 6 observation wells. Previous DMG correspondence in the record, and
the information reviewed during this inspection did not indicate and unusual anomalies or trends in
neither groundwater recharge nor monitored groundwater quality parameters. Surface water monitoring
is not required. The 1994 primary haulroad certifications were in the file. These roads have been
reclassified as access roads since cessation of mining and thus haulage activity.
The records show CEC accepting 45, 854 tons of CCB during calendar year 2003; and 12,467 tons of
mine waste rock (from Clear Creek AML remediation sites) during 1998 and 1999. CEC had 2003 aerial
photo work completed into 2' contour interval maps which has necessitated minor backfilling and
grading volumetric changes in the record. Liability insurance is current through 4/1/2005.
