MINESITE INSPECTION NARRATIVE 7
Refuse Pile Inspections---There are three waste piles
on the mine. The Sutey and rock tunnel piles are
being inspected on a quarterly basis. The old refuse
pile is only being inspected twice a year. DMG stated
that the semi-annual basis for the old refuse pile was
approved in the permit. Inspections of the old refuse
pile were not done in the first quarter of 1993, and
third quarter of 1992, out of the last four quarters.
The approved Colorado program requires quarterly
inspections, therefore, violation 1 of the TDN was
issued for this non-compliance.
The inspections indicate that waste was last added to
the Sutey pile on 1/25/91. The reports mention
unstable areas on the west side and southwest edge of
the Sutey pile, and a small area on the east side of
the Dutch Creek flume.
Water Monitoring--- Surface and Ground water
monitoring records were reviewed for 1992 through the
present. Mid-Continent Resources still has the
responsibility to monitor surface and groundwater
according to their approved plan because the
reclamation bond for the mine has not been forfeited.
In addition, the operator is required to have an NPDES
permit covering the discharge points from the mine.
The permit for the mine, CO-0000396, is valid until
December 31, 1993 . Per Ms. Delaney, a request for
renewal of the permit has been submitted to the
Colorado Department of Health. Discharge records for
the first quarter of 1993 were reviewed. There were
no reported violations. Discharge sampling for the
second quarter of 1993 had been done but the lab
results were not posted as of this inspection.
A required annual hydrology report, the latest being
1992, has been submitted to the Division for review.
A copy of the report was also on file near the
minesite. The operator is required to sample surface
water bi-annually from 5 different sites, Station #20-
Coal Creek, Station 15-Dutch Creek, Station #3-Bear
Creek, Station #3-Sutey Creek and Disney Creek in
addition to the discharge points. They also have
committed to sampling the spring beneath the Sutey
refuse disposal pile. Field parameter testing is
required for measuring flow, temperature, Ph and
conductivity. Grab samples collected from the same
stations require testing for 11 different parameters.
Ground water sampling is done at 10 different sites
