2. The approximate depth and thickness, if applicable, of all known coal seams, known groundwater-bearing strata, and other known gas or oil strata between the surface and the depth to which the corehole is proposed to be drilled;

3. If casing is proposed to be set, the entire casing program, including the diameter of each string of casing, the starting point and depth to which each string is to be set, whether or not the casing is to remain in the hole after the completion of drilling, and the extent to which each string is to be cemented, if applicable;

4. A plan which shows the proposed manner of plugging or replugging the corehole; and

5. The procedures to be followed to protect the safety of persons working in an underground coal mine for any corehole to be drilled within 200 feet of or into active workings. The permittee shall give notice of such drilling to the mine operator and the chief at least two working days prior to drilling.
