Temporary Surface Management Plan <br />During the course of day to day operations at the mine and during planned construction activities, <br />instances occur whereby it is necessary to utilize temporary management techniques to maintain <br />sound environmental practices. The goal of temporary surface management is to control soil <br />erosion and protect other resources, including air, water quality, vegetation on small azeas both in <br />and out of the disturbed area boundary. <br />Temporary surface management can be divided into two categories. The first includes revegetation <br />efforts carved out on small areas subject to re-disturbance within 5 years. The second category <br />includes physical management practices involving placing protective barriers or structures to <br />maintain sediment control or otherwise prevent environmental damage. <br />The temporary surface management plan is as follows: <br />1. Small areas that aze disturbed will be seeded with the temporary seed mix if appropriate. It has <br />been determined during the first five yeaz pemvt term that it is not necessary to replace seed <br />bed quality material in every instance i.e., the subsoil can be adequately reseeded for short-term <br />purposes. Seed bed quality material will be replaced if subsoil is not adequate. Other <br />management practices will be used as necessary depending on the site, such as roughening the <br />surface by ripping or scarifying, regrading or contouring, adding chemical soil stabilizers, <br />watering for dust control with or without chemical additives, mulching and other feasible <br />methods as deemed appropriate. <br />2. Temporary physical management practices will include the following: <br />- temporary drainage ditches or berms to control surface runoff. <br />- straw bales to filter sediment laden runoff and allow ponding for settling. <br />- silt fence in the same application as straw bales. <br />- rock rip-rap to prevent erosion. <br />- temporary plastic (visqueen, etc.) ditch liners. <br />- temporary drainage structures such as PVC pipe or other suitable devices. <br />- pumping or transferring of water from one location to another to be treated in existing <br />sediment control structures or waste water treatment plant. <br />- sand bags to divert runoff or contain runoff. <br />- other practices that aze deemed appropriate to prevent environmental damage. <br />The temporary surface management plan is intended to be used only on a short-term basis until <br />more permanent approved plans can be put into effect or constructed. <br />Revegetation Maintenance <br />Soil erosion is controlled by using mulch, matting, chemical stabilizers, or other appropriate <br />techniques. Rills and gullies greater than nine inches deep aze filled and stabilized. During <br />revegetation, maintenance activities aze conducted parallel to the contour unless such activities <br />prove hazazdous to equipment and/or operators. Mulch is used where needed after planting to <br />control erosion until vegetation becomes established. <br />Baze patches of failed planting aze prepazed and replanted. Where there is evidence of poor soil <br />1.05-63 Revised Nw. 1996 PR07; Rev. Jan 1997 TR79; Rev. Sept. 1997 MR 227;Rev, Apsil 2006 PRIO <br />
