Any augering operation associated with surface mining shall be conducted in a manner to maximize recoverability of mineral reserves remaining after mining operations and reclamation are complete. All auger holes shall be sealed with an impervious and noncombustible material in order to prevent drainage except where the Department determines that the resulting impoundment of water in such auger holes may create a hazard to the environment or the public health or safety, provided that augering may be prohibited if necessary to maximize the utilization, recoverability or conservation of the solid fuel resources or to protect against adverse water quality impacts.
