• 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 1966; 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 sales <br />were taken at the New Elk Mine (see Map 9). <br />Samples 5, 12 and 13 were taker. 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 gair 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 revegetatior. 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 <br />coal. <br /> <br />2.04-40(A) Revised 03/16/87 <br />
