RESPONSE <br />Surface mining is not proposed in this permit revision application; therefore, this subsection does not require a <br />response. <br />(3) Underaround Mining <br />(a) The description shall include a general statement of the geology (stratigraphy and structure <br />within the proposed area to be affected over the life of the operation, down to and including the first aquifer, and other <br />coal seams, if any, below the lowest coal seam to be mined. The geology for the areas proposed to be affected by <br />surface operations and facilities, those surface lands underlain by the coal to be mined, and the coal to be mined shall <br />be separately described as follows including a map and cross sections prepared to the standards of 2.10 which shows: <br />(i) Nature, depth, and thickness of the coal seams to be mined, any coal or rider seams <br />above the seam(s) to be mined, each stratum of the overburden, and the stratum immediately below the lowest coal <br />seam to be mined; <br />(ii) A geologic map with geologic cross sections of the proposed permit area, including <br />coal crop lines and the strike and dip of the coal to be mined; <br />(iii) The geology for those surface lands within the permit area which are underlain by <br />the coal seam to be extracted and the geology of the coal seam itself including_ <br />(A) The logs of drill holes, test borings or other samples obtained by methods <br />approved by the Division showing the lithologic characteristics, physical properties and thickness of each stratum, <br />which may be impacted. <br />(B) The location of subsurface water, if encountered; and <br />(C) Chemical analysis of the coal seam for acid - forming or toxic - forming <br />materials including, but not limited to, the pyrite, marcasite and sulphur content; <br />(D) The chemical analysis of the stratum immediately above and below the coal <br />seam to be mined or any other stratum to be affected, for acid - forming, toxic - forming, or alkalinity producing <br />materials and their content as determined by the Division, and <br />(E) For proposed room and pillar mining operations, the thickness and <br />engineering __properties of clays or clay shale, if any, in the stratum immediately above and below each coal seam to be <br />mined. <br />M R 14 -282 2.04 -12.2 09/08/14 <br />
