STATUS: Forgiven <br />Stipulation No. 16 <br />ht the event that the aerial photogrammetric monument surveys fail to meet the stipulated accuracy criteria, <br />MCC shall utilize traditional field survey techniques to establish the reasons for.lack of correlation. If the <br />results cannot be correlated, MCC shall resume traditional field survey monument monitoring, in <br />compliance with the accuracy criteria and standazds contained with stipulation no. 15. <br />STATUS: Forgiven <br />Stinulatiou No. 17 <br />The Division directs MCC to submit reports of its subsidence monitoring program on asemi-annual basis, <br />cotnntencing one month after the installation and initial surveying of the subsidence monuments. Further, <br />due to the complexity of the permit azea geology, presence of landslides and steep slopes, and sensitive <br />hydrologic elements, MCC is deeded to submit a proposed subsidence monitoring report format to the <br />Division for approval. This report format should recognize the importance of continual update of <br />subsidence data interpretation, monitoring of Bound water levels and spring flows, monitoring of mine <br />inflow, and subsurface ground conditions which could be correlated to subsidence prediction. This report <br />format shall be approved by the Division prior to the commencement of extraction of coal within the <br />subsidence test panel designated in Appendix A to MCC's Novembere 1984 permit revision appflcation <br />(Panel 1 W-1 S). <br />STATUS: Terminated August 27, 1993 <br />Stinulation No. 18 <br />The Division deeds MCC to complete a detailed analysis of the potential effects upon the slope stability of <br />the landslide deposits adjoining Beaver Reservov. MCC shall install and monitor an appropriate set of <br />monuments on the landslide deposits in order to observe the potential displacement of the landfotm. The <br />detailed analysis shall be completed and submitted to the Division for review, prior to request for approval <br />to extract coal beneath the landslide deposits adjoining Beaver Reservoir. <br />STATUS: Future <br />Stinulation No. 19 <br />The Division directs MCC, as a portion of its subsequent permit applications for the mine, to submit <br />revised subsidence evaluations. The subsidence evaluation for each permit period requested shall <br />incorporate the results of subsidence monitoring and the landslide stability studies completed to date, as <br />stipulated above. Particulaz attention shall be focused upon designated safe area buffers, to be observed in <br />future mining beneath critical azeas, including the Dry Fork of Minnesota Creek and Beaver Reservoir and <br />the landslide deposits adjoining it. The amended subsidence evaluations shall include the proposal of <br />appropriate subsidence monitoring networks within each of these designated azeas. <br />STATUS: Terminated <br />Stinulation No. 21 <br />The applicant must install monitoring wells in, conduct pumping test on, and monitor water levels and <br />water quality in the alluvium of Dry Fork, Lick Creek, South Prong, and Horse Creek one yeaz prior to <br />mining within the watersheds of these streams. The applicant shall submit to the Division the data and <br />results of these tests and monitoring along with projected impacts prior to conducting mining within any of <br />the watersheds. <br />
