(i) Nature, depth, and thickness of the coal seams to be mined, any coal or rider <br />seams above the seam to be mined, each stratum of the overburden, and the stratum immediately below the <br />• lowest coal seam to be mined; <br />coal to be mined; <br />(ii) The proposed permit area, including coal outcrops and the strike and dip of the <br />(b) (i) Test borings or core samples from the proposed permit area shall be collected and <br />analyzed down to and including either the stratum immediately below the lowest coal seam to be mined or any <br />aquifer below the lowest coal seam to be mined which may be adversely affected by mining, whichever is deeper, in <br />order to provide the following data in the description: <br />(A) Location of subsurface water zones, if encountered; <br />(B) Logs of drill holes, test borings or other sampling methods <br />as approved by the Division showing the lithologic characteristics and thickness of each stratum and each coal <br />seam; <br />(C) Physical properties of each stratum within the overburden <br />and interburden including texture, overall swell, and other information sufficient to determine compatibility, <br />erodability and an overall estimate of overburden and interburden swell; <br />(D) Chemical analysis of each stratum within the overburden <br />and interburden and either the stratum immediately below the lowest coal seam to be mined or any aquifer <br />below the lowest coal seam to be mined which may be adversely affected by mining, whichever is deeper, to <br />identify, at a minimum, those horizons which contain potential acid - forming, toxic - forming, or <br />• alkalinity-producing materials; and <br />(E) Analyses of the coal seam, including, but not limited to, an <br />analysis of the sulfur, pyrite, and marcasite content. <br />(ii) Borehole spacing and physical and chemical analyses of core <br />samples shall be determined in consultation with the Division. <br />(iii) If required by the Division, test borings, core samplings or <br />samples obtained by other methods approved by the Division shall be collected and analyzed to greater depths <br />within the proposed permit area, or for areas outside the proposed permit area to provide for evaluation of the <br />impact of the proposed activities on the hydrologic balance. <br />(iv) An applicant may request that the requirement for a statement of <br />the results of the test borings or core samples be waived by the Division. The waiver may be granted only if the <br />Division makes a written determination that the statement is unnecessary because other equivalent information <br />is accessible to it in a satisfactory form. The source(s) of such equivalent information shall be referenced in the <br />Division's written determination and the information itself shall be made readily accessible by the Division for <br />public review as required by 1.08 if such information has not been determined to be of a confidential nature in <br />accordance with 2.02.7 and 2.07.5. <br />PR09 -08 2.04 -12.1 04/10/09 <br />
