• 2.05.4 page 5 <br />National King Coal, LLC, with the assistance of the Mined Land Reclamation Division, has <br />established approved re-vegetation success standards and seed mix criteria (See Appendix 9). The <br />company has also relied on the assistance of James Ranches Landscaping, Inc., a local reclamation <br />contractor, in developing the re-vegetation procedures. <br />After [he placement and spreading of the topsoil, soil tests will be taken. Upon receipt of the <br />test results and recommendation by testing laboratory, the correct amount of fertilizer will be applied. <br />Soil preparation will be accomplished by using a disk capable of disturbing the soil to a depth <br />of 4". This operation will also incorporate the fertilizer into the soil, as well as conditioning the soil for <br />seed reception. In case of a loose seed bed, a cultipacker to firm the ground will be used Following <br />drilling. <br />On slopes of 3:1 or less the seed should be planted with a drill equipped with double disc <br />openers and depth bands. Spacings of discs should be no more than 10". Seed should be planted to an <br />approximate depth no deeper than 1/2". On slopes of 2:1 or greater, broadcast seeding may be used. <br />Planting of seed will occur between October 15 and April 30, or between July 15 to August 30. <br />Recommended seed and planting rates are detailed in a report prepared by Colorado Division of <br />Minerals and Geology entitled: ESTIMATING FORM - REVEGETATION WORK (See Appendix 9). <br />Upon completion of seeding, all azeas will receive two (2) tons of hay or straw mulch per acre. <br />The material is [o be applied in an even manner by use of hand mulching or a mechanical blower. On <br />3:1 slopes or less the mulch will be crimped into the soil by use of a straight blade crimper of spacings <br />of no[ more than ]0". <br />• Since no pre-disturbance vegetation data was collected, the following re-vegetation success <br />standards are based on SCS Range site data and baseline data from similar areas. Since NKC's permit <br />application was approved, the Division has been analyzing data pertaining to species diversity. Based <br />on this analysis, the Division reaffirmed the success criteria for cover, production and shrub density, <br />and modified the criteria for species diversity as addressed below: <br />Cover -The standard for herbaceous cover is 30 percent to be measured by the point <br />intercept method. <br />2. Production -The standard for herbaceous productivity is 500 pounds per acre of dry <br />biomass measured by the harvest method using a minimum 1/2 M2 quadrat. <br />Shrub Density -The standard for woody plant density is a tninimutn 600 stems per acre. <br /> <br />January 1998 <br />
