Chapter 1501:13-13 Miscellaneous Surface and Underground Mining
(1) Auger mining operations shall be conducted in accordance with the requirements of Chapters 1501:13-9 to 1501:13-11 of the Administrative Code, except as provided in this rule.
(2) The chief may prohibit auger mining, if necessary, to:
(a) Maximize the utilization, recoverability, or conservation of the solid-fuel resource; or
(b) Protect against adverse water-quality impacts.
(B) Coal recovery.
(2) Auger mining shall be planned and conducted to maximize recoverability of mineral reserves remaining after the operation and reclamation are complete.
(3) Each person who conducts auger mining operations shall leave areas of undisturbed coal, as approved by the chief, to provide access for future underground mining operations to coal reserves remaining after augering is complete, unless it is established that the coal reserves have been depleted or are so limited in thickness or extent that it will not be practicable to recover the remaining coal. This determination shall be made by the chief upon presentation of appropriate technical evidence by the operator.
(C) Hydrologic balance.
(2) All auger holes, except as provided in paragraph (C)(3) of this rule, shall be:
(a) Sealed within seventy-two hours after completion with an impervious and noncombustible material, if the holes are discharging water containing acid- or toxic-forming material. If sealing is not possible within seventy-two hours, the discharge shall be treated commencing within seventy-two hours after completion to meet applicable effluent limitations and water-quality standards until the holes are sealed; and
(b) Sealed with an impervious noncombustible material, as contemporaneously as practicable with the augering operation, as approved by the chief, if the holes are not discharging water containing acid- or toxic-forming material.
(3) Auger holes need not be sealed with an impervious material so as to prevent drainage if the chief determines that:
(a) The resulting impoundment of water may create a hazard to the environment or public health or safety; and
(b) The drainage from the auger holes will:
(i) Not pose a threat of pollution of surface water; and
(E) Backfilling and grading.
General. Auger mining shall be conducted in accordance with the backfilling and grading requirements of rule 1501:13-9-14 of the Administrative Code.
(F) Protection of underground mining. Auger holes shall not extend closer than five hundred feet (measured horizontally) to any abandoned or active underground mine workings, except as approved in accordance with rule 1501:13-9-08 of the Administrative Code.
(G) Remining. Auger mining operations that affect previously mined areas containing a preexisting highwall shall comply with the requirements of rule 1501:13-9-14 of the Administrative Code except as provided in paragraph (K) of rule 1501:13-4-12 of the Administrative Code.

(A) Special requirements. Coal mining and reclamation operations conducted on prime farmland shall meet the following requirements:
(2) Soil materials to be used in the reconstruction of the prime farmland soil shall be removed before drilling, blasting, or mining, in accordance with paragraphs (B) and (C) of this rule and in a manner that prevents mixing or contaminating these materials with undesirable material. Where removal of soil materials results in erosion that may cause air and water pollution, the chief shall specify methods to control erosion of exposed overburden.
(B) Soil reconstruction specifications. The chief shall use soil reconstruction specifications established by the U.S. soil conservation service for prime farmland soil removal, storage, replacement, and reconstruction as guidelines in carrying out his responsibilities under paragraph (F) of rule 1501:13-4-12 of the Administrative Code and Chapter 1501:13-7 of the Administrative Code.
(C) Soil removal.
(1) Coal mining and reclamation operations on prime farmland shall be conducted to:
(a) Separately remove the topsoil or other suitable soil materials if such soil materials will create a final soil having a greater productive capacity than that which existed prior to mining. If not utilized immediately the material shall be stockpiled separately from other rooting medium and spoil; and
(b) Separately remove the B horizon of the soil, or a combination of B horizon and underlying C horizon, or other suitable soil material if such soil material will create a reconstructed soil of equal or greater productive capacity than that which existed before mining.
(2) The minimum depth of soil and soil material to be removed for use in reconstruction of prime farmland soils shall be sufficient to meet the soil replacement requirements of paragraph (E)(1) of this rule.
(D) Soil stockpiling. If not utilized immediately, the topsoil or other suitable soil materials specified in paragraph (C)(1)(a) of this rule and the B horizon or other suitable soil materials specified in paragraph (C)(1)(b) of this rule shall be stored separately from each other and from spoil. These stockpiles shall be placed within the permit area where they are not disturbed or exposed to excessive water or wind erosion before the stockpiled horizons can be redistributed. Stockpiles in place for more than thirty days shall meet the requirements of paragraph (D) of rule 1501:13-9-03 of the Administrative Code.
(E) Soil replacement. Coal mining and reclamation operations on prime farmland shall be conducted according to the following:
(1) The minimum depth of soil and soil material to be reconstructed for prime farmland shall be forty-eight inches, or a depth equal to the depth of a subsurface horizon in the natural soil that inhibits root penetration, whichever is shallower. The chief shall specify a depth greater than forty-eight inches, wherever necessary to restore productive capacity. Soil horizons shall be considered as inhibiting root penetration if their densities, chemical properties, or water supplying capacities restrict or prevent penetration by roots of plants common to the vicinity of the permit area and have little or no beneficial effect on soil productive capacity;
(2) Soil material shall only be replaced on land which has been first returned to final grade and scarified according to paragraph (C) of rule 1501:13-9-03 of the Administrative Code, unless site-specific evidence is provided and approved by the chief showing that scarification or its equivalent will not enhance the capability of the reconstructed soil to achieve equivalent or higher levels of yield;
(3) The soil horizons or other suitable soil materials shall be replaced with proper compaction and uniform depth;
(4) The B horizon or other suitable material specified in paragraph (C)(1)(b) of this rule shall be replaced to the thickness needed to meet the requirements of paragraph (E) of this rule;
(5) The topsoil or other suitable soil materials specified in paragraph (C)(1)(a) of this rule shall be replaced as the final surface soil layer. This surface soil layer shall equal or exceed the thickness of the original soil, as determined in paragraph (F)(2)(a) of rule 1501:13-4-12 of the Administrative Code, and shall be placed in a manner that protects the surface layer from wind and water erosion before it is seeded or planted; and
(6) Nutrients and soil amendments shall be applied as needed to establish vegetative growth quickly.
