• 2.04.6 <br />(3)(a)(ii) <br />A geologic map with geologic cross sections of the proposed permit, including <br />coal crop lines and the strike and dip of the coal to be mined is presented as <br />Map 07. <br />(3)(a)(iii)(A)&(B) <br />(3)(a)(iii)(C) <br />r~ <br />U <br />I• <br />See drill hole logs presented on Map 08 Geologic Cross Section and Monitoring <br />Hole Completion Drawings in Exhibit 3. <br />Three drill holes from the D-2 Seam were cored and analyzed for forms of sulfur: <br />The cores were obtained in late 1975 or early 1976 and analyzed by Hazen <br />Research, Inc. from Golden, Colorado. See Exhibit 6 for a copy on the <br />laboratory reports. The results of the analysis follows: <br />SULFUR FORMS D-2 SEAM <br /> Sulfur Forms (%) <br />Drill Hole Pyritic Organic Sulfate Total <br />DH-12 0.01 0.35 0.00 0.36 <br />DH-22A 0.02 0.38 0.00 0.40 <br />DH-8A 0.05 0.39 0.00 0.44 <br />Reference: Reclaiming mine soils and overburden in the western United States, <br />by R. Dean Williams and Gerald E. Schuman, Editors, for the following <br />discussion regarding acid forming material in the D-2 Seam coal. <br />Iron pyrite is an acid forming material. The reaction of the pyritic sulfur is: <br />2FeS2+ 7~/zO2 + 7H2 ---> 2Fe(OH)3 + 2HZS0, <br />PR-08 2-04 - 16 - 7/03 <br />/9 P~Rave9 <br />9~7-503 <br />
