If a methodology is proposed that has not been <br />previously employed or accepted by CDMG, such methodology will be submitted for approval prior to <br />employment. <br />Determination of revegetation success in achieving the total vegetation cover and total herbaceous <br />production success criteria will be based on quantitative statistical means. The Student's t test is a robust <br />statistical test to evaluate the equivalency of two sample means or a sample mean with a specified standard <br />(Zar, 1974). This test will be employed to test the null hypothesis that the sample mean for revegetated <br />pazcel parameter is equal to or greater than 90 percent of the cover or production success criterion. Standard <br />statistical probability ranges will be employed in the determination of whether the revegetated area mean is <br />significantly less than the criterion. When the revegetated azea mean is not statistically significantly less <br />than the applicable criterion at a 90 percent confidence level employing a 10 percent alpha error probability <br />level, the revegetation will have been demonstrated successful. <br />The following is the reclamation seed mix for the National King Mine. <br />RECLAMATION SEED MIX <br /> <br />SEEDS/ SEED <br />RATE <br />COMMON NAME SPECIES NAME CHARACTER SEEDS/LB S FT Ibs Is /ac <br /> <br />Craminoids <br />Thicks ike Wheat rass Ara ron das stacb um N,C-S,S 150,000 4 Ll6 <br />Western Wheat rass A ro ronsm/tb/i N,C-S,S 120,000 7 2.54 <br />Bluebunch Wheat rass A ro ron s icatum N,C-S,B 150,000 6 1.74 <br />Mountain Brome 8romus mar inatus N,C-S,B 72,000 3 1.82 <br />Shee Fescue Festuca ovina N,C-S,B 570,000 4 0.31 <br />Switch rass Panicum vir atum N,W-S,B 350,000 6 0.75 <br /> <br />Forbs <br />Lewis flax Linum lewis/i N,C-S,P 285,000 3 0.46 <br />Small Burnett San a/sorbs minor I,C-S,P,L 50,000 3 2.61 <br />Globemallow S baeralcea coccinea N,W-S,P 500,000 4 <br /> <br />Totals 40 11.38 <br />N NATIVE <br />I INTRODUCED <br />C-S COOL SEASON <br />W-S WARM SEASON <br />S SOD-FORMER <br />B BUNCH CRASS <br />A ANNUAL <br />P PERENNIAL <br />L LEGUME <br />RECLAMATION TIME TABLES <br />Activi <br />I) Dismantling surface facilities, <br />sale of salvaged equipment and <br />coal stockpiles, backfilling <br />and sealing of mine portals. <br />Time Period <br />2 weeks <br />
