TR-76 2.04-42 (revised 6/7/2022) <br />Samples were taken to a depth of 18 inches in July 1986. The <br />Division requested additional samples of waste, topsoil borrow and <br />undisturbed topsoil to be taken to a depth of 36 inches in 1 foot <br />increments. Sample locations 1 through 10 were taken in July 1986; sample <br />locations 11 through 19 were taken in December 1986. Sample locations 1, <br />2, 17, 18 and 19 were taken at the Golden Eagle Mine; the remaining samples <br />were taken at the New Elk Mine ( see Map 9) . <br />Samples 5, 12 and 13 were taken from the topsoil borrow, area. <br />Sample 5 was taken to a depth of 1.5 feet and exhibited a relatively high <br />SAR for undisturbed soil. Samples 12 and 13 have no apparent limiting <br />factors. The sandy clay loam texture of 5 indicates SAR should not pose <br />significant problems in revegetation. The remaining undisturbed samples <br />are generally fair to good for direct seeding and/or topsoil salvage. The <br />topsoil pile at the New Elk (Sample 9) has a relatively high pH of 8.8. <br />Waste samples have high SAR's. The predominant textural <br />classification is clay loam. The SAR effects on revegetation will be <br />mitigated as WFC plans to topsoil these areas. <br />A pH of 4.6 was reported in the 3 foot depth increment at sample <br />location 10. WFC suspects slight acid formation results from oxidation of coal. <br />2.04-10 Vegetation Information <br />A vegetation map has been prepared which shows the area which is <br />affected by the New Elk Mine surface facilities and additional area which <br />will be disturbed within the permit term. The various plant communities <br />are delineated based on aerial mapping and field mapping which has been <br />a:mpleted by Uniscale Corporation. Uniscale has conducted two extensive <br />surveys of the areas around the surface facilities to determine species <br />composition, cover, productivity, and woody plant density in 1980 and 1981. <br />Map 10, Vegetation, has been prepared which delineates each plant community <br />within the permit boundary.
