Stipulation No 17
THE DIVISION DIRECTS WECC TO SUBMIT REPORTS OF ITS SUBSIDENCE 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 LANDSLIDES
AND STEEP SLOPES, AND SENSITIVE HYDROLOGIC ELEMENTS, WECC 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 SUBSIDENCE TEST PANEL
DESIGNATED IN APPENDIX A TO WECC'S NOVEMBER, 1984 PERMIT REVISION
APPLICATION (PANEL 1W-1S I.
Stipulation No. 18
THE DIVISION DIRECTS WECC TO COMPLETE A DETAILED ANALYSIS OF THE
POTENTIAL EFFECTS UPON THE SLOPE STABILITY OF THE LANDSLIDE DEPOSITS
ADJOINING BEAVER RESERVOIR. WECC SHALL INSTALL AND MONITOR AN
APPROPRIATE SET OF MONUMENTS ON THE LANDSLIDE DEPOSITS IN ORDER TO
OBSERVE THE POTENTIAL DISPLACEMENT OF THE LAND FORM. THE DETAILED
ANALYSIS SHALL BE COMPLETED AND SUBMITTED TO THE DIVISION FOR REVIEW,
PRIOR TO REQUEST FOR APPROVAL TO EXTRACT COAL BENEATH 7HE LANDSLIDE
DEPOSITS ADJOINING BEAVER RESERVOIR.
Stipulation No. 19
THE DIVISION DIRECTS WECC AS A PORTION OF ITS SUBSEQUENT PERMIT
APPLICATIONS FOR THE MINE, TO SUBMIT REVISED SUBSIDENCE EVALUATIONS. THE
SUBSIDENCE EVALUATION FOR EACH PERMIT PERIOD REQUESTED SHALL INCORPORATE
THE RESULTS OF SUBSIDENCE MONITORING AND THE LANDSLIDE STABILITY STUDIES
COMPLETED TO DATE, AS STIPULATED ABOVE. PARTICULAR ATTENTION SHALL BE
FOCUSED UPON DESIGNATED SAFE AREA BUFFERS, TO BE OBSERVED IN FUTURE
MINING BENEATH CRITICAL AREAS, INCLUDING THE DRY FORK OF MINNESOTA CREEK,
AND BEAVER RESERVOIR AND THE LANDSLIDE DEPOSITS ADJOINING IT. THE
AMENDED SUBSIDENCE EVALUATIONS SHALL INCLUDE THE PROPOSAL OF APPROPRIATE
SUBSIDENCE MONITORING NETWORKS WITHIN EACH OF THESE DESIGNATED AREAS.
Stipulation No, 20
THE DIVISION DIRECTS WECC TO LIMIT EXTRACTION WITHIN THE DEFINED
"CRITICAL AREA BUFFER ZONES" BENEATH THE DRY FORK OF MINNESOTA CREEK AND
LICK CREEK, AS DEPICTED ON EXHIBIT 3.4,4:8:1; TO NO MORE THAN THIRTY (30)
PERCENT OF THE IN-PLACE COAL.
