- (a) Each application shall contain a narrative description of the surficial and subsurface geology under and adjacent to the proposed mining permit area down to the first stratigraphic unit below the level where CCB would be placed. This description shall include structural geology of the mining permit and adjacent areas that would influence the movement of surface and ground water.(b) The description shall include information on permeability of the sides and bottom of proposed CCB placement sites in the mining permit area, obtained from visual inspection and laboratory testing of rock strata or other earthen materials that would be in direct contact with placed CCB. The permeability of the in situ material, or any liner material approved by the Department, on the sides and bottom of the proposed CCB placement site must not exceed 10-5 cm/sec. If accessibility is prohibited to test the permeability of the sides and bottom of the proposed placement site, core samples may be taken contiguous to the pit or a representative area of the permit site which corresponds to the same geologic stratum. These testing sites must not exceed 10-5 cm/sec.(c) Logs of holes drilled to obtain geologic information shall be provided.(d) If required, the Department may require the collection of additional geologic information and analyses in addition to that required by this Paragraphs (a) and (b) of this Section.
