THE AERIAL PHOTOGRAMMETRIC SURVEYS SHALL BE DETERMINED BY A COMPARISON OF <br />• TRIANGULATION BENCH MARK MONUMENT FIELD AND AERIAL PHOTOGRAMMETRIC SURVEY <br />RESULTS FOLLOWING EACH SEMI-ANNUAL SURVEY. THE RESULTS OF EACH AERIAL <br />PHOTOGRAMMETRIC SURVEY SHALL BE ACCEPTED AS ACCURATE IN THE EVENT THAT THE <br />AERIAL PHOTOGRAMMETRIC AND MOST RECENT ANNUAL TRIANGULATION MONUMENT FIELD <br />SURVEY RESULTS CORRELATE WITH AN AVERAGE TRIANGULATION MONUMENT LOCATION <br />DEVIATION OF LESS THAN 02 FEET VERTICALLY AND HORIZONTALLY, WITH TRIANGULATION <br />MONUMENT LOCATION DEVIATIONS OF LESS THAN 0.4 FEET VERETICALLY AND <br />HORIZONTALLY FOR LESS THAN 83% OF THE TRIANGULATION MONUMENTS, AND WITH NO <br />SINGLE TRIANGULATION POINT LOCATION DEVIATION VERTICALLY OR HORIZONTALLY IN <br />EXCESS OF 0.8 FEET. <br />STATUS: FORGIVEN <br />Stipulation No. 16 <br />IN THE EVENT THAT THE AERIAL PHOTOGRAMMETRIC MONUMENT SURVEYS FAIL TO MEET <br />THE STIPULATED ACCURACY CRITERIA, MCC SHALL UTILIZE TRADITIONAL FIELD SURVEY <br />TECHNIQUES TO ESTABLISH THE REASONS FOR LACK OF CORRELATION. IF THE RESULTS <br />CANNOT BE CORRELATED, MCC SHALL RESUME TRADITIONAL FIELD SURVEY MONUMENT <br />MONITORING IN COMPLIANCE WITH THE ACCURACY CRITERIA AND STANDARDS WITHIN <br />STIPULATION NO. 15. <br />• STATUS: FORGIVEN <br />Stipulation No. 17 <br />THE DIVISION DIRECTS MCC TO SUBMIT REPORTS OF ITS SUBSIDENCE MONITORING <br />PROGRAM ON A SEMI-ANNUAL BASIS, COMMENCING ONE MONTH AFTER THE INSTALLATION <br />AND INITIAL SURVEYING OF THE SUBSIDENCE MONUMENTS. FURTHER, DUE TO THE <br />COMPLEXITY OF THE PERMIT AREA, GEOLOGY, PRESENCE OF LANDSLIDES AND STEEP SLOPES, <br />AND SENSITIVE HYDROLOGIC ELEMENTS, MCC IS DIRECTED TO SUBMIT A PROPOSED <br />SUBSIDENCE MONITORING REPORT FORMAT TO THE DIVISION FOR APPROVAL. THIS REPORT <br />FORMAT SHOULD RECOGNIZE THE IMPORTANCE OF CONTINUAL UPDATE OF SUBSIDENCE <br />DATA INTERPRETATION, MONITORING OF GROUND WATER LEVELS AND SPRING FLOWS, <br />MONITORING OF MINE INFLOW, AND SUBSURFACE GROUND CONDITIONS WHICH COULD BE <br />CORRELATED TO SUBSIDENCE PREDICTION. COMMENCEMENT OF EXTRACTION OF COAL <br />WITHIN THE SUBSIDENCE TEST PANEL DESIGNATED IN APPENDIX A TO MCC'S NOVEMBER <br />1984 PERMIT REVISION APPLICATION (PANEL I W- IS). <br />STATUS: TERMINATED 8/27/1993. <br />Stipulation No. 18 <br />• THE DIVISION DIRECTS MCC TO COMPLETE A DETAILED ANALYSIS OF THE POTENTIAL <br />EFFECTS UPON THE SLOPE STABILITY OF THE LANDSLIDE DEPOSITS ADJOINING BEAVER <br />RESERVOIR. MCC SHALL INSTALL AND MONITOR AN APPROPRIATE SET OF MONUMENTS ON <br />60
