CONST. MANAGEMENT
On February 1, 2005, the DMG issued a notice of violation to Bov~ie Resources, LLC, for failure
to provide a geotechnical analysis that demonstrates the factor of safety of the in place and
proposed coal mine waste bank no. 2 is 1.5 orgreater using site specific characteristics (moist
unit weight) and strength parameters of cohesion and angle of internal friction from coal
processing waste material that have been placed on the coal mine waste bank no. 2.
The steps necessary to abate the violation were to provide a geotechnical analysis that
demonstrates the factor of safety of the in-place and proposed coal mine waste bank no. 2 is 1.5
orgreater. The required geotechnical analysis was transmitted to the DMG by letter dated
March 17. 2005.
The results of the stability study required that the slopes of the refuse pile be no steeper than
5h:1 v with 15' wide terraces on 50' intervals with the first 50 foot bench sloped no steeper than
2.5h:1 v. /''~~
Although Bowie satisfied the abatement steps listed in the uolation, the ivD i~ considers the
reconfiguration of the refuse pile slopes to be an additional abatement step. Bowe has started
flattening the refuse pile slopes but the work is not complete. The work is not complete because
the surface layer on the refuse pile slopes was saturated during the winter and spring.
Therefore, work could not be performed on the slopes until just recently. During the last week,
rain has further delayed the slope flattening project. Additionally, working on a saturated slope
surface with a track type dozer could result in loss of control of the equipment which could
endanger the heavy equipment operator.
Bowie expects to have the slope flattening project complete within the next 45 days. Please
extend the abatement deadline for the referenced NOV 45 days.
Sin~ly
