(b) The following general performance standards are applicable to all surface mines and require the operation, at a minimum, to:
- (1) Maximize the utilization and conservation of the solid fuel resource being recovered to minimize reaffecting the land in the future through surface mining;
- (2) Restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is reasonable likelihood so long as the use or uses do not present any actual or probable hazard to public health or safety or pose any actual or probable threat of water diminution or pollution and the permit applicant’s declared proposed land use following reclamation is not considered to be impractical or unreasonable, inconsistent with applicable land use policies and plans, involves unreasonable delay in implementation or is violative of federal, state or local law;
(3) Except as provided in subsection (c) of this section, with respect to all surface mines, backfill, compact where advisable to ensure stability or to prevent leaching of toxic materials and grade in order to restore the approximate original contour: Provided, That in surface mining which is carried out at the same location over a substantial period of time where the operation transects the coal deposit and the thickness of the coal deposits relative to the volume of the overburden is large and where the operator demonstrates that the overburden and other spoil and waste materials at a particular point in the permit area or otherwise available from the entire permit area is insufficient, giving due consideration to volumetric expansion, to restore the approximate original contour, the operator, at a minimum, shall backfill, grade and compact, where advisable, using all available overburden and other spoil and waste materials to attain the lowest practicable grade, but not more than the angle of repose, to provide adequate drainage and to cover all acid-forming and other toxic materials in order to achieve an ecologically sound land use compatible with the surrounding region: Provided, however, That in surface mining where the volume of overburden is large relative to the thickness of the coal deposit and where the operator demonstrates that due to volumetric expansion the amount of overburden and other spoil and waste materials removed in the course of the mining operation is more than sufficient to restore the approximate original contour, the operator shall, after restoring the approximate contour, backfill, grade and compact, where advisable, the excess overburden and other spoil and waste materials to attain the lowest grade, but not more than the angle of repose, and to cover all acid-forming and other toxic materials in order to achieve an ecologically sound land use compatible with the surrounding region and the overburden or spoil shall be shaped and graded in a way as to prevent slides, erosion and water pollution and revegetated in accordance with the requirements of this article: Provided further, That the secretary shall propose rules for legislative approval in accordance with article three, chapter twenty-nine-a of this code governing variances to the requirements for return to approximate original contour or highwall elimination and where adequate material is not available from surface mining operations permitted after the effective date of this article for:
- (A) Underground mining operations existing prior to August 3, 1977; or (B) for areas upon which surface mining prior to July 1, 1977, created highwalls;
- (4) Stabilize and protect all surface areas, including spoil piles, affected by the surface mining operation to effectively control erosion and attendant air and water pollution;
- (5) Remove the topsoil from the land in a separate layer, replace it on the backfill area or, if not utilized immediately, segregate it in a separate pile from other spoil and, when the topsoil is not replaced on a backfill area within a time short enough to avoid deterioration of the topsoil, maintain a successful vegetative cover by quick growing plants or by other similar means in order to protect topsoil from wind and water erosion and keep it free of any contamination by other acid or toxic material: Provided, That if topsoil is of insufficient quantity or of poor quality for sustaining vegetation, or if other strata can be shown to be more suitable for vegetation requirements, then the operator shall remove, segregate and preserve in a like manner any other strata which is best able to support vegetation;

(7) Ensure that all prime farmlands are mined and reclaimed in accordance with the specifications for soil removal, storage, replacement and reconstruction established by the United States Secretary of Agriculture and the Soil Conservation Service pertaining thereto. The operator, at a minimum, shall:
- (A) Segregate the A horizon of the natural soil, except where it can be shown that other available soil materials will create a final soil having a greater productive capacity and, if not utilized immediately, stockpile this material separately from other spoil and provide needed protection from wind and water erosion or contamination by other acid or toxic material;
- (B) segregate the B horizon of the natural soil, or underlying C horizons or other strata, or a combination of the horizons or other strata that are shown to be both texturally and chemically suitable for plant growth and that can be shown to be equally or more favorable for plant growth than the B horizon, in sufficient quantities to create in the regraded final soil a root zone of comparable depth and quality to that which existed in the natural soil and, if not utilized immediately, stockpile this material separately from other spoil and provide needed protection from wind and water erosion or contamination by other acid or toxic material;

- (9) Where augering is the method of recovery, seal all auger holes with an impervious and noncombustible material in order to prevent drainage except where the secretary determines that the resulting impoundment of water in the auger holes may create a hazard to the environment or the public welfare and safety: Provided, That the secretary may prohibit augering if necessary to maximize the utilization, recoverability or conservation of the mineral resources or to protect against adverse water quality impacts;
(10) Minimize the disturbances to the prevailing hydrologic balance at the mine site and in associated off-site areas and to the quality and quantity of water in surface and groundwater systems both during and after surface mining operations and during reclamation by:
(A) Avoiding acid or other toxic mine drainage by such measures as, but not limited to:
