• Temporary Stabilization Mixture <br />Temporary revegetation may be established at the mine to provide <br />surface protection and increase soil erosion resistance, thus improving <br />stability of slopes associated with structures or facilities (i.e., <br />temporary road embankments, parking area cut or fill slopes, temporary <br />diversions, etc.), and to minimize hydrologic impacts and maximize sediment <br />control structure effectiveness. The temporary stabilization seed mixture <br />has been formulated with species capable of protecting soil surfaces <br />through the establishment of quick growing annual and perennial grasses and <br />forbs. The temporary stabilization mixture is contained in Table 9.4-3. <br />This mixture will be applied at an approximate rate of 15 P.L.S. per square <br />foot. It is expected that purity and germination characteristics of seed <br />stock contained in the mixture will result in a variation of the bulk pound <br />application rate each year. <br />Table 9.9-3 <br />Temporary Stabilization Seed Mixture <br /> Percent of Mixture Seeding Rate <br />• Species By No. of P.L.S.

When this monitoring indicates a deficiency that can be <br /> corrected using inte rseeding, an interseeding plan will be developed and <br /> forwarded to the CMLRD as a minor revision to be inserted into the permit <br /> document as part of Appendix 9.9-E. The in terseeding plan will: 1) <br />• Identify the area to be interseeded; 2) Includ e the monitoring information <br /> Renewal-3 9.4-12 June 13, 1997 <br />
