West Elk Mine 2004 Annual Hydrology Report 38 <br />6.2 Proposed Revisions to the Hydrologic Monitoring Program <br />Proposed revisions to [he existing hydrologic monitoring program include: 1) phasing out the <br />monitoring of the surface station in Lower Gribble Gulch and the springs in the Gribble Gulch area <br />(G-26, G-28a, G-30, G-31, G-35, and G-49), and 2) adding new surface water and spring <br />monitoring sites in the South of the Divide permit area and the Dry Fork and West Flatiron LBA <br />areas. <br />Several of the Project's monitoring wells (SOM-2H, SOM-16H, SOW-1, SOM 45-H1, and 96-27- <br />1) aze no longer functional because of casing failures. These wells can no longer be monitored and <br />should be eliminated from the monitoring program. A series of new monitoring wells will be <br />installed in August-September 2005 to replace these non-functional wells and to more effectively <br />monitor the current and future mining areas. A summary of the proposed revisions to the <br />hydrologic monitoring system is presented in Table 12. <br /> <br /> <br />.august 2005 HydrnGen, Inc. <br />
