Section 312IAC25-4-38. Surface mining permit applications; environmental resources information; cross sections, maps, and plans

   The application shall include cross sections, maps, and plans showing the following:

(1) Elevations and locations of test borings and core samplings.

(2) Elevations and locations of ground water monitoring stations and locations of surface water monitoring stations used to gather data for water quality and quantity 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 area and adjacent areas.

(6) Location and extent of subsurface water, if encountered, within the proposed permit area or adjacent areas.

(7) Location of surface water bodies such as streams, lakes, ponds, springs, constructed or natural drains, and irrigation ditches within the proposed permit area 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, and noncoal waste disposal, dams, embankments, other impoundments, air pollution control facilities, and water treatment 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.

(11) Sufficient slope measurements or cross sectional profiles with slope measurements to adequately represent the existing land surface configuration of the proposed permit area, measured and recorded according to the following:

(A) Each measurement shall consist of an angle of inclination, expressed as a percent, along the prevailing slope.

(B) Where the area has been previously mined, the measurements shall extend at least one hundred (100) feet beyond the limits of mining disturbances.

(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.

(12) Elevations and locations of monitoring stations used to gather data on fish and wildlife and air quality, if required, in preparation of the application.

(13) Maps, plans, and cross sections included in a permit application, that are required by this section shall be prepared by or under the direction of and certified by a registered professional engineer or professional geologist, with assistance from experts in related fields, such as land surveying and landscape architecture.
