In addition, diversion ditches and/or berms were constructed at the toe of all waste rock <br />facilities and the West Pit highwall to collect runoff from the slopes or the highwalls and <br />contain this runoff This prevents sediment and other constituents from reaching surface <br />waters in the area. <br />The following BMPs will continue to be used as appropriate to remove sediments from <br />stormwater runoff emanating from the East and West Pits and the Waste Rock Facilities <br />B and C areas: <br />1. The stormwater system will be inspected periodically (i.e., spring and fall) and <br />the system will be maintained to remove accumulations of sediment collected <br />in sedimentation basins or retention ponds. <br />2. Final reclamation of any remaining unreclaimed portions of waste rock <br />facilities will be conducted as soon as possible. <br />Refer to Figure 1 to see the placement of these BMPs. Current reclamation status is <br />described in Table 1. <br />6.2 Waste Rock Facilities <br />Source <br />Waste rock was placed in the waste rock facilities by end-dumping from mine haul <br />trucks. As previously mentioned, the slopes were constructed at 1.SH:1V. Under these <br />conditions, runoff from the waste rock aeeas would produce sediment that must be <br />removed before release to the surface water system. However, concurrent reclamation <br />and current reclamation practices have been completed at every waste rock facility with <br />only limited areas requiring final reclamation. At a minimum, all slopes, crests, and tops <br />of the waste rock facilities have been partially reclaimed. This reclamation includes <br />contouring, topsoiling, and vegetation. The majority of the waste rock facilities have <br />been completely reclaimed. <br />Risk Assessment <br />As previously discussed, geochemical testing was performed to determine the potential <br />for surface water runoff from the waste rock facilities to contain pollutants other than <br />sediment. These tests indicate that waste rock constituents do not leach constituents in <br />Battle Mountain Resources, Inc. Telesto Solutions, Inc. <br />,,,n ma,~o~n»n~erma~~~menwm~.ea 18 May 3, 2002 <br />
