Only the 12 <br />monuments with displacement greater than the survey error of <br />0.1 ft/1000 ft are provided in this table. <br />4.2 Inclinometer Evaluation <br />Three (3) inclinometers were installed in October 1998 (198-1, 198-2, and 198-3) to monitor the <br />stability of the south wall of the North Pit. Data collected in 1999, 2000, 2002, indicate minimal <br />slope movement (less than 0.3 ft/year) and is consistent with the surface monument survey data. <br />' Homestake will continue to monitor these three inclinometers at a minimum of every two years <br />unless surface monuments detect increasing slope movement. <br />' Two temporary inclinometers were installed in Piezometers P-8 and P-10 during the winterof 1997- <br />1998 to provide data in the spring of 1998. These inclinometers were made redundant by the <br />installation of inclinometers 198-1, 198-2, and 198-3. The inclinometers in P-8 and P-10 remain <br />' installed, but are not surveyed on a regular basis. Should surface monuments detect increasing <br />slope movement, data could be collected from these combination piezometers/inclinometers. <br />4.3 Pinnacle Mine Workings Monitoring <br />A concrete plug was constructed in the Pinnacle Adit in September 1995. Authorization for the <br />' placement of the Pinnacle Adit plug was requested by Homestake in April 1995, through Technical <br />Revision #4 (TR4) -Pinnacle Adit Closure, Pitch Project, Technical Revision for Permit #77-4HR <br />(Golder Associates, Inc.). Conditional approval of the Technical Revision request was granted by <br />' the Colorado -Division Of Minerals and Geology in a letter dated May 26, 1995. <br />The intention of the plug was to hydrologically seal the Pinnacle Adit and allow the area around the <br />' mine workings to resaturate. The resaturation of the workings was predicted to re-establish a <br />geochemically reducing environment and lower the solubility of uranium and radium within the <br />2002_ RECLAMATION RPT.DOC <br />
