OEI will modify the permit as necessary to address the <br />measures to be implemented. <br />Fertilization <br />No fertilization was employed during the revegetation of the Carbon Junction Mine. <br />Revegetation Success Criteria <br />The criterion for evaluation of revegetation success for the approved post-mining land <br />use is vegetation cover. This vegetation cover must be sufficient to control erosion. <br />Based on sampling at other mines sites in the area and the pre-mining vegetation studies, <br />a revegetation cover standard was established. <br />The following will be the revegetation success criteria for the Carbon Junction Mine: <br />Vegetation Cover <br />Vegetation cover of the reclaimed area willbe successful when vegetation cover is 40 <br />percent with 90 percent statistical confidence. <br />Herbaceous Production <br />There is no herbaceous production revegetation success standard. <br />Woody Plant Density <br />There is no woody plant density revegetation success standard. <br />Species Composition <br />There is no species composition revegetation success standard. <br />Abridged Permit Document 5-14 Permit Renewal RN04 4/2014 <br />
