Section III - Status of Stipulations <br /> (continued) <br /> Stipulation No. 4 <br /> The operator shall install and begin monitoring one monitoring well <br /> located over the panel to be monitored for subsidence one year prior to <br /> mining this panel . The hole shall be completed in the stratum overlying <br /> the "D" seam. Water levels in this well shall be drawn twice per year for <br /> the parameters listed in Appendix A of this Findings Document. The <br /> operator shall submit to the Division a well completion report, monitoring <br /> schedule, groundwater level data and water quality data prior to mining <br /> this panel . <br /> Resolved: CWI drilled DH-58 on December 10, 1982 and submitted a <br /> completion report on February 4, 1983. This well never yielded water and <br /> was removed from the hydrologic monitoring program in the 1986 permit <br /> revision. Drill hole 70 currently intercepts the stratum overlying the <br /> "D" seam. <br /> Stipulation No. 5 <br /> The Division directs Colorado Westmoreland, Inc. to submit reports of its <br /> subsidence monitoring program on a semi-annual basis, commencing one month <br /> after the installation and initial surveying of the subsidence monuments . <br /> Further, due to the complexity of the permit area geology, presence of <br /> steep slopes , and sensitive hydrologic elements , Colorado Westmoreland, <br /> Inc. is directed to submit a proposed subsidence monitoring report format <br /> to the Division for approval . This report format should recognize the <br /> importance of continual update of subsidence data interpretation, <br /> monitoring of groundwater levels and spring flow, monitoring of mine <br /> inflow, and subsurface ground conditions which could be correlated to <br /> subsidence prediction. This report format shall be approved by the <br /> Division prior to the commencement of extraction of coal within the <br /> 5 north panel off the 8th east main of the Orchard Valley Mine. <br /> Resolution: Reporting format was received May 14, 1982. The first report <br /> was received August 15, 1983 and accepted August 30, 1983. CWI committed <br /> to semi-annual submittal of subsidence report monitoring in the permit <br /> document. Subsidence monitoring and reporting frequency was reduced to <br /> annual requirements by the approval of Technical Revision No. 6 on <br /> January 28, 1989. COVCC committed to these monitoring requirements in <br /> Section 2.05.6(6)(c)(i )(B) of the permit document. <br /> -6- <br />
