IV. Conclusions: <br />Subsidence monument and power pole surveys disclosed no unusual developments during <br />the reporting period. Subsidence magnitudes and projected draw angle~o were within the <br />anticipated ranges previously documented for the area. <br />Structures remained essentially unaffected during the period with the exception of the <br />predicted impacts to the power poles and the bowed cross member on structure H65. No <br />adverse impacts, i.e. imminent failure of structure, were evident with reg:~rd to these lines. <br />2000_2ndHaltSubReport.doc Page 2 of 2 02/16/01 <br />
