quantities that would affect the surface water quality as most constituents were below <br />analytical detection levels. The risk of sediment transfer is greatly reduced by concurrent <br />and continued reclamation of the facilities consisting of contouring, topsoiling, and <br />vegetative stabilization. <br />Applicable BMPs and Good Housekeeping Practices <br />When the Project was designed and constructed, BMRI employed stonnwater best <br />management practices in the development of the waste rock facilities as discussed in the <br />approved DMG permit and technical revisions. The primary best management practice <br />for minimizing sediment generation and stormwater exposure to waste rock materials was <br />the concurrent and continuing reclamation practiced at the site. Vegetative establishment <br />reduces sediment generation and the potential for exposure of waste rock materials. With <br />concurrent reclamation, early vegetation of the lower benches or lifts provides filtration <br />for sediments present in runoff from unreclaimed or upper lift areas reclaimed at a later <br />date. Small catch benches were left in place as each subsequent lift was graded. This <br />catch bench provides a mechanism for slowing runoff from the slopes and allowing <br />collection of sediment. <br />In addition, ditches and/or berms were constructed at the toe of all waste rock facilities to <br />collect runoff from the slopes and contain and convey this runoff to the sedimentation or <br />retention ponds. This acts to prevent sediment and other constituents from reaching <br />surface waters in the area. <br />The following BMPs will continue to be used as appropriate to remove sediments from <br />the South Waste Rock Facility and Waste Rock Facility D: <br />1. The stonnwater system will be periodically inspected (i.e., spring and fall) and <br />the system will be maintained to remove accumulations of sediment collected <br />in the basins or 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 />Bat7le Mountain Resources, /nc. Telesro Solutions, Inc. <br />,a~ mano.mwnre.mn~asem:mn+mi_eec 19 May 3. 2002 <br />
