monitoring plan for this portion of the mine to verify that its <br />prediction of zero subsidence was accurate. <br />Monitoring of subsidence near the Tatum property never took <br />place, however, because construction of the First North Main of <br />the Golden Eagle mine ceased in 1988, before the mine had reached <br />the houses that required monitoring. As stated by DMG on page <br />two of its response to the TDN: <br />As a further method of ensuring protection of the AVF, <br />the original permit required the Golden Eagle Mine to <br />demonstrate compliance with Rule 2.05.6(6)(c) and <br />monitor five adobe houses situated within the AVF that <br />would overlie the areas of less than 50$ extraction. <br />These five houses, originally planned to be room-and- <br />pillar undermined per the 1984 approved permit by the <br />First North Main, were required to be monitored per <br />Rule 2.05.6(6)(c)(i)(D), requiring quarterly monitoring <br />to commence one month prior to the initiation of mining <br />beneath the houses. Construction of the First North <br />Main ceased in 1988 before reaching the house closest <br />to the Main. Of these five structures, none have been <br />undermined. As such, surveys of these five structures <br />have not been conducted. <br />Since monitoring of subsidence over the First North Main did <br />not take place as scheduled because of the closure of that <br />portion of the mine, DMG required Basin, in order to verify <br />Basin's prediction that no subsidence would occur, to monitor <br />subsidence over the nearby Third North Main. Basin monitored <br />subsidence at eight monuments situated over the Third North Main <br />for the 1st, 2nd, and 3rd quarters of 1988. DMG reported that no <br />subsidence was observed at these•locations. Since the required <br />monitoring had been accomplished and there had been no detected <br />25 <br />
