data; and the baseline data from an adjacent proposed mine (Sackett Mining <br />Company's Shalako Mine, permit application 79-4 UG/C) which exhibited similar <br />environmental characteristics: National King Coal accepted the Division's <br />recommendations: <br />During the permit renewal, the Division reviewed the revegetation success <br />criteria: Since the permit application document for the King Coal Mine was <br />approved, the Division has been analyzing data pertaining to species <br />diversity: Based on this analysis; the Division and National King Coal <br />believed a change in the species diversity criteria was in order: The <br />Division reaffirms the success criteria for cover; production and shrub <br />density; and modifies the criteria for species diversity as addressed below. <br />A: Cover - The standard for herbaceous cover is 30 percent to be <br />measured either by ocular estimates using a minimum 1/2 M2 <br />quadrat or by the point-intercept method. <br />B: Production - The standard for herbaceous productivity is 500 pounds <br />per acre of d~y biomass measured by the harvest method using a <br />minimum 1/2 M quadrat. <br />C. Shrub Density - The standard for woody plant density is a minimum <br />600 stems per acre: <br />D: Species Diversity - The standard for species diversity using the <br />species composition approach is as follows: <br />Species Requirements* <br />Grasses <br />Cool Season 2 <br />Warm Season 2 <br />Forbs 2 <br />Shrubs 2 <br />*No single species shall be represented by more than 40 percent relative <br />cover or less than 3 percent relative cover for grass species; or less <br />than 1 percent relative cover for forb and shrub species: <br />The operation is in compliance with the requirements of this section: <br />XIII. Fish and Wildlife - Rules 2:04:11; 2:05.6(2) and 4:18 <br />Information pertaining to fish and wildlife is presented in Section 2.04.11 of <br />the permit application: <br />National King Coal contacted the local office of the Colorado Division of <br />Wildlife requesting their assistance in assessing any potential impacts the <br />mining operation may have on wildlife: A copy of the Division of Wildlife's <br />response is found in Section 2.04:11 page 3: <br />The general area of the mine site is considered critical deer winter range. <br />However; it is the Division of Wildlife's opinion that; because of the long <br />history of mining in the area, many of the impacts to wildlife have already <br />_1g_ <br />
