RE: Recommended Settlement of NOV C-84-090
Mid-Continent Resources, Inc.
I. FINDING OF VIOLATION
During the May, 1984 Inspection, Jim Herron, of the Mined Land
Reclamation Division, observed that drainage ditches to the mine #1 and
#2 sediment control system had been breached and that the two sediment
ponds were more than 60% filled with sediment. A violation was issued
for failure to minimize disturbance to the prevailing hydrologic
balance. Specifically, the violation was concerned with the failure to
maintain the sediment and drainage control system.
During the hearing, the operator presented convincing evidence that the
sediment ponds were not yet filled to the 60% level with sediment.
Specific records of pond clean-out volumes were presented. One of the
drainage ditches which had breached prior to the inspection was
functioning properly at the time of the inspection. It was assumed
that the ditch had breached during the previous week' s excessive runoff
events.
One of the drainage ditches was breached at the time of the inspection,
causing drainage to short-circuit the sediment control system. This
condition was considered serious enough to warrant issuance of a
violation. Based on oral testimony, written records, slides, and
photographs, I recommend that violation NOV 84-090 be modified.
t Specifically, the citations related to the sediment-filled ponds and
C_ t the ditch which had breached, but was functioning properly at the time
of the inspection, should be dropped. The citation for the breached
drainage ditch which was causing short-circuiting should be retained.
\` A modified version of NOV 84-090 should be upheld.
