7. The "Geotechnical Monitoring Plan for the Bruce Park Landslide" found in Exhibit 20 of Volume <br />IIIA, describes the sensor array system in place on the landslide mass and the response plan that <br />will be initiated if movement of the landslide triggers the alarm. An alert will be sounded if a <br />movement of 0.1 inches occurs in any 12 hour period. If an alert is also sounded during the <br />following 12 hour period, and credible evidence suggests significant movement, than an on site <br />inspection of the landslide will be performed. If the movement is found to be real and is in excess <br />of 0.2 inches per 12 hours, the information will be reported and field personnel will remain on <br />site. E-mails and text messaging will notify the appropriate personnel of the alarms. <br />8. Bowie Resources is submitting quarterly monitoring reports on the seismic network. The reports <br />are filed in Exhibit 18 of Volume IIIA. <br />9. Permit application text in Section 2.04.7 of Volume I, pages 2.04-22 through 2.04-40, was revised <br />to describe the ground water baseline and operational monitoring situation. <br />10. The HydroGeo technical memo "B-Seam and Strata Above B-Seam Water Quality Analysis, <br />Bowie Coal Mine", found in Exhibit 3 of Volume III, was submitted in support of Bowie <br />Resources' contention that no further ground water monitoring wells are needed down gradient of <br />the proposed B-seam workings. Using this information and the revised text in Section 2.04.7 of <br />Volume I and revised Map 10 and Map 11 in Volume II, Bowie was able to show that the current <br />baseline and operational ground water quality for the B-seam and above the B-seam will not vary <br />significantly from south to north. <br />11. The "Stability Evaluation of Third North Mains - Hubbard Creek Study Area" is filed in Exhibit <br />16 of Volume IIIA and demonstrates the long term stability of the room and pillar mains under a <br />portion of Hubbard Creek that are proposed in PR-10. <br />12. The "Prediction of Surface Deformation Resulting from Longwall Mining in the Dove Gulch <br />Area" can be found in Exhibit 17 of Volume IIIA and was submitted to show the effects on the <br />surface from proposed mining under Dove Gulch. <br />13. The "Determination of the Angle of Draw" is in Exhibit 21 of Volume IIIA and was submitted to <br />confirm the angle of draw using field data. <br />14. The "Terror Creek Reservoir Area Pre-Subsidence Inspection" was submitted to document the <br />pre-mining conditions of the Bruce Park Dam and Terror Creek Reservoir. It is filed in Exhibit 22 <br />of Volume IIIA. <br />15. The "Dove Gulch Hydrology Report" is in Exhibit 19 of Volume IIIA and was submitted to show <br />that Dove Gulch is an ephemeral stream. <br />20
