Current through Reg. 49, No. 28; July 12, 2024
(a) The application shall include cross
					 sections, maps, and plans showing:
(1)
					 elevations and locations of test borings and core samplings;
(2) elevations and locations of monitoring
					 stations used to gather data on water quality and quantity, fish and wildlife,
					 and air quality, if required, in preparation of the application;
(3) nature, depth, and thickness of the coal
					 seams to be mined, any coal or rider seams above the seam to be mined, each
					 stratum of the overburden, and the stratum immediately below the lowest coal
					 seam to be mined;
(4) all coal crop
					 lines and the strike and dip of the coal to be mined within the proposed permit
					 area;
(5) location and extent of
					 known workings of active, inactive, or abandoned underground mines, including
					 mine openings to the surface within the proposed permit and adjacent
					 areas;
(6) location and extent of
					 subsurface water, if encountered, within the proposed permit or adjacent areas,
					 including, but not limited to areal and vertical distribution of aquifers, and
					 portrayal of seasonal differences of head in different aquifers on cross
					 sections and contour maps;
(7)
					 location of surface-water bodies such as streams, lakes, ponds, springs,
					 constructed or natural drains, and irrigation ditches within the proposed
					 permit and adjacent areas;
(8)
					 location and extent of existing or previously surface-mined areas within the
					 proposed permit area;
(9) location
					 and dimensions of existing areas of spoil, waste, coal development waste, and
					 noncoal waste disposal, dams, embankments, other impoundments, and water
					 treatment and air pollution control facilities within the proposed permit
					 area;
(10) location, and depth if
					 available, of gas and oil wells within the proposed permit area and water wells
					 in the permit area and adjacent areas; and
(11) sufficient slope measurements to
					 adequately represent the existing land-surface configuration of the area
					 affected by surface operations and facilities, measured and recorded according
					 to the following:
(A) each measurement shall
					 consist of an angle of inclination along the prevailing slope extending 100
					 linear feet above and below or beyond the coal outcrop or the area to be
					 disturbed or, where this is impractical, at locations specified by the
					 Commission;
(B) where the area has
					 been previously mined, the measurements shall extend at least 100 feet beyond
					 the limits of mining disturbances, or any other distance determined by the
					 Commission to be representative of the premining configuration of the land;
					 and
(C) slope measurements shall
					 take into account natural variations in slope, to provide accurate
					 representation of the range of natural slopes and reflect geomorphic
					 differences of the area to be disturbed.
