MLRD Findings Document: Stipulation No. 11, p. 9
OSM Findings Document: Stipulation No. 27, p. 8
OSM TER: Stipulation No. 23 (listed as No. 2 under Section 817.54), p. 71
25. Stipulati ors: THE DIVISION DIRECTS ARCO TO COMPLETE THE INSTALLATION OF THE
SUBSIDENCE MONITORING NETWORK PRIOR TO THE INITIATION OF EXTRACTION OF COAL
WITHIN THE PANEL DESIGNATED IN EXHIBIT 3.4.8.A FOR SUBSIDENCE MONITORING. THE
MONITORING NETWORK IS DESIGNED TO MONITOR THE FIFTH PANEL FROM THE ENTRANCE OF
THE MAIN PORTAL, WEST FROM THE MAIN, WITHIN SECTION 16. THIS MONITORING NET-
WORK SHALL CONSIST OF SUBSTANTIAL MONUMENTS DESIGNED TO RESIST FROST-HEAVE,
FIRE, AND THE ACTIONS OF CATTLE AND WILDLIFE. ARCO SHALL SUBMIT A MONUMENT
DESIGN TO TXE DIVISION FOR APPROVAL. MONUMENT INSTALLATION SHALL NOT OCCUR
PRIOR TO RECEIPT OF DIVISION APPROVAL OF THE MONUMENT DESIGN.
MLRD Findings Document: Stipulation No. 41, p. 46
OSM Findings Document: Stipulation No. 38, p. 11
OSM TER: This stipulation has not been included in the TEA.
26. Stipulation: TXE DIVISION DIRECTS ARCO TO SUBMIT REPORTS OF ITS SUBSIDENCE
MONITORING PROGRAM ON R 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 RND STEEP
SLOPES, AND SENSITIVE HYDROLOGIC ELEMENTS, ARCO 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
PANEL DESIGNED IN EXHIBIT 3.4.8.A FOR SUBSIDENCE MONITORING.
MLRD Findings Document: Stipulation No. 42, p. 47
OSM Findings Document: Stipulation No. 39, P. 11
OSM TEA: Stipulation No. 32, p. 160 as follows:
32. Although the applicant intends to perform subsidence measurements
upon a greater frequency than stated in the rule (1 month vs. 1 quarter)
the applicant does not describe the method or content of its reports
to the regulatory authority. Due to the presence of landslides,
questionable hydrologic effects and the lack of local subsidence
history it is required that the applicant negotiate a formal report-
ing system with the regulatory authority. This precedure should
recognize the importance of continual update of data interpretation,
monitoring of ground water levels, and mining conditions in the panels
which could be correlated to subsidence prediction.
27. Stipulation: THE DIVISION DIRECTS RRCO TO COMPLETE A DETAILED ANALYSIS OF
THE POTENTIAL EFFECTS OF SLOPE STABILITY UPON THE STABILITY OF THE LANDSLIDE
DEPOSIT LOCATED ABOVE THE TOWN OF SOMERSET, REFERENCED ON PAGE 30 OF EXHIBIT
3.4.8.R OF THE REVISED PERMIT APPLICATION. ARCO SHALL INSTALL AND MONITOR AN
APPROPRIATE SET OF MONUMENTS ON THE LANDSLIDE DEPOSIT, IN ORDER TO OBSERVE
POTENTIAL DISPLACEMENT OF THE LAND FORM. THE DETAILED ANAYSIS SHALL BE
