v ACCURACY CRITERIA, MCC SHALL UTILIZE TRADITIONAL FIELD SURVEY TECHNIQUES TO ESTABLISH THE REASONS FOR LACK OF CORRELATION. IF THE RESULTS CANNOT BE CORRELATED, MCC SHALL RESUME TRADITIONAL FIELD SURVEY MONUMENT MONITORING IN COMPLIANCE WITH THE ACCURACY CRITERIA AND STANDARDS WITHIN STIPULATION NO. 15. STATUS: FORGIVEN Stipulation No. 17 THE DIVISION DIRECTS MCC 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, MCC 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. COMMENCEMENT OF EXTRACTION OF COAL WITHIN THE SUBSIDENCE TEST PANEL DESIGNATED IN APPENDIX A TO MCC’S NOVEMBER 1984 PERMIT REVISION APPLICATION (PANEL 1W-1S). STATUS: TERMINATED 8/27/1993. Stipulation No. 18 THE DIVISION DIRECTS MCC TO COMPLETE A DETAILED ANALYSIS OF THE POTENTIAL EFFECTS UPON THE SLOPE STABILITY OF THE LANDSLIDE DEPOSITS ADJOINING BEAVER RESERVOIR. MCC 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 THE LANDSLIDE DEPOSITS ADJOINING BEAVER RESERVOIR. STATUS: TERMINATED 1/26/2007, MINING NOT PROPOSED IN AREA Stipulation No. 19 THE DIVISION DIRECTS MCC, 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. STATUS: COMPLIED WITH; 6/2/2006 BY PR-10 SUBMITTAL Stipulation No. 20 THE DIVISION DIRECTS MCC TO LIMIT EXTRACTION WITHIN THE DEFINED “CRITICAL AREA BUFFER ZONES” BENEATH THE DRY FORK OF MINNESOTA CREEK AND LICK CREEK, AS DEPICTED ON MAP 50 (FORMERLY EXHIBIT 3.4.4.8.1), TO NO MORE THAN THIRTY (30) PERCENT OF THE IN-PLACE COAL. STATUS: TERMINATED. Stipulation No. 21
