March Monthly/I"' Quarter Report - 2002 <br />Page 2 <br />"B List" Projects <br />• Columbus Mine Portals -Mine Waste Dumps <br />• London Mine Portals -Waste Dumps <br />Work, permitting or arrangement for access is not planned until it becomes evident that <br />the work plans for these projects require implementation. <br />Mayflower Facility -Upland Hydrological Control <br />Tailings Pond No. 4 Surface Drainage Modification <br />Tailings Pond No. 4 Upland Groundwater Diversion <br />DMG has inspected the sites and approved the projects as complying with the work plans <br />and MLR Standards. <br />Due to the scant snowfall this past winter, these sites were beginning to melt out by the <br />end of March although no progress pictures were taken. The diversions were working and <br />diverting water. It is not anticipated that flow quantities diverted during 2002 will <br />approach those observed since implementation of the projects due to the limited snowfall <br />received over the 2001-2002 winter. <br />Cement Creek Diversion and Water Treatment <br />Cement Creek diversion and water treatment was active throughout March and the l~' <br />quarter. During the quarter, basically all of Cement Creek was diverted for treatment with <br />the remaining American Tunnel flow although at quarter end, Cement Creek flow had <br />increased to the point that intake control to the treatment system was required. <br />The March 2002 monitoring results for; dissolved metals in the AT-004 discharge; <br />Cement Creek (CC-1B); American Tunne] flow before treatment (AT-INFEL); and <br />Cement Creek below the AT-004 discharge point (CC-20) are attached. <br />
