STIPULATIONS
Attached to Permit No. C-038-81
Colorado Westmoreland, Inc.
Orchard Valley Mine
1. Colorado Westmoreland, Inc. must obtain a letter from the State Historical
Preservation Office within 30 days of the permit issuance stating whether or
not there are any places Zocated within the proposed permit area which are
listed or eligible for listing in the National Register of Historic Places.
2. Colorado Iestmoreland, Inc. must submit to the Division in final form the
vegetation inventory of the Orchard Valley Mine, as outlined in the draft
vegetation inventory report by Harney-White Ecological Consultants, Inc.,
dated August 6, 1981. This final report must be incorporated into the permit
application as part of the vegetation appendix in Volume 7. This report must
be submitted to the Division within 30 days of the permit issuing.
3. The operator is directed by the Division to install the monitoring network shown
on Map 28B above the 5 North panel of the 8th East main prior to November 1,
1981. In order to determine the adequacy of the simplistic monument proposed
for use in this network, the applicant shall install appropriate benchmarks
to allow quarterly monitoring of the monument network for a minimum of 9
months prior to mining within the subject panel. Prior to the installation
of the monument network benchmarks, the operator shall obtain approval from
the Division of the benchmark's location and construction. Following receipt
of that approval, the operator shall amend Map 28B to indicate the location
of the approved benchmarks.
4. The operator shall install and begin monitoring one monitoring well located
over the panel to be monitored for subsidence one year prior to mining this
panel. The hole shall be completed in the stratum overlying the "D" seam.
Water levels in this well shall be monitored monthly as weather permits, and
water quality samples shall be drawn twice per year for the parameters listed
in Appendix A of this findings document. The operator shall submit to the
Division a well completion report, monitoring schedule, ground water level
data and water quality data prior to mining tlv s panel.
5. The Division directs Colorado [5estmoreland, Inc. to submit reports of its sub-
sidence monitoring program on a semi-annual basis, commencing one month after
the installation and initial surveying of the subsidence monuments. Further,
due to the complexity of the permit area geology, presence of steep slopes,
and sensitive hydrologic elements, Colorado Festmoreland, Inc. is directed
to submit a proposed subsidence monitoring report format to the Division for
approval. This report format should recognize the importance of continual
update of subsidence data interpretation, monitoring of ground water Levels
and spring flows, monitoring of mine inflow, and subsurface ground conditions
which could be correlated to subsidence prediction. This report format
shall be approved by the Division prior to the commencement of extraction of
coal within the 5 North panel off the 8th East main of the Orchard Valley Mine.
6. The operator shall install and be yin monitoring one monitoring well located
at drainage node 22, as shown on Map No. 13. The well shall be completed
within the bedrock below the surficial material within 60 days of the permit
issuing. Water levels, pH, electro-conductivity, and temperature in this
well must be monitored monthly as weather permits, and water quality samples
shall be drawn quarterly for the parameters listed in Appendix A. This moni-
toring data must be submitted to the Division quarterly. The applicant shall
submit to the Division a well completion report and monitoring schedule within
30 days after the well is completed.
7. Within 60 days of permit issuance, Colorado Westmoreland, Inc. must provide
the Division with a specific crop production standard for the orchard area.
Pending Division approval, this standard will be used in evaluating revege-
tation success within the orchard vegetation type.
8. Within 60 days of permit issuance, Colorado Westmoreland, Inc. must provide
the Division with an appropriate, justifiable shrub/tree density standard which
will be sufficient to meet the approved post-mining land use for the reclaimed
surface. This standard must be based upon a recommendation from the Division
of Wildlife, and must include the findings of the technical references/
sources used to establish this standard.
