Section 4VAC25-130-773.16 - Criteria for permit approval or denial; existing structures

(a) No application for a permit or revision which proposes to use an existing structure in connection with or to facilitate the proposed surface coal mining and reclamation operation shall be approved, unless the applicant demonstrates and the division finds, in writing, on the basis of information set forth in the complete application that:

(1) If the applicant proposes to use an existing structure in accordance with the exemption provided in 4VAC25-130-701.11(d)(1)(i):

(i) The structure meets the performance standards of the Act and Subchapter VK; and

(ii) No significant harm to the environment or public health or safety will result from use of the structure.

(2)

(i) If the applicant proposes to use an existing structure in accordance with the exemption provided in 4VAC25-130-701.11(d)(1)(ii):

(A) The structure meets the performance standards of the Act and the initial regulatory program;

(B) No significant harm to the environment or public health or safety will result from use of the structure; and

(C) The performance standards of the initial regulatory program are at least as stringent as the performance standards of Subchapter VK.

(ii) If the division finds that the structure meets the criteria of 4VAC25-130-701.11(d)(1)(ii), the division shall require the applicant to submit a compliance plan for modification or reconstruction of the structure and shall find prior to the issuance of the permit that:

(A) The modification or reconstruction of the structure will bring the structure into compliance with the design and performance standards of Subchapter VK;

(B) The risk of harm to the environment or to public health or safety is not significant during the period of modification or reconstruction; and

(C) The applicant will monitor the structure to determine compliance with the performance standards of Subchapter VK.

(b) Should the division find that the existing structure cannot be reconstructed without causing significant harm to the environment or public health or safety, the applicant will be required to abandon the existing structure. The structure shall not be used for or to facilitate surface coal mining operations after the effective date of issuance of the permit. Abandonment of the structure shall proceed on a schedule approved by the division in compliance with 4VAC25-130-816.132 or 4VAC25-130-817.132.

(c) An existing structure shall be deemed to meet the performance standards of the Act and Subchapter VK, if it meets the standards of this Subparagraph.

(1) General standards. The existing structure shall meet the following general standards:

(i) Land use restoration. The existing structure shall be capable of being restored to a satisfactory postmining land use in accordance with the requirements of 4VAC25- 130-816.133 and 4VAC25-130-817.133, which use or uses shall not present any actual or probable hazard to public health or safety or pose any actual or probable threat of water diminution or pollution.

(ii) Topsoil storage. Stockpiled topsoil and other substitute or supplemental materials shall be placed on a stable area and protected from wind and water erosion, unnecessary compaction, and contaminants which lessen the capability of the material to support vegetation when redistributed.

(iii) Surface area stabilization. All surface areas shall be stabilized and protected to control erosion and attendant air and water pollution.

(iv) Acid and toxic-forming materials. Drainage from acid-forming, toxic-forming, or otherwise harmful materials shall not cause pollution of ground or surface waters and shall minimize adverse effects on plant growth and land uses.

(v) Hydrologic balance: Water quality standards and effluent limitations.

(A) Federal and State water quality statutes, regulations, standards, or effluent limitations shall not be violated.

(B) Discharges of water from disturbed areas shall comply with the effluent limitations of 4VAC25-130-816.42 or 4VAC25-130-817.42.

(C) No land within 100 feet of a perennial stream or an intermittent stream in accordance with 4VAC25-130-816.57 or 4VAC25-130-817.57 shall be disturbed by surface mining activities; unless the water quantity and quality within 100 feet of the surface mining activities are not adversely affected, the division specifically authorizes surface mining activities closer to or through such a stream upon a finding that the original stream channel will be restored, and the requirements of Subparagraph (c)(5) of this section are satisfied.

(vi) Off-site protection. Areas outside the permit area shall be protected from slides or damage.

(vii) Protection of fish, wildlife, and related environmental values. Disturbances and adverse impacts on fish, wildlife, and related environmental values shall be minimized using the best technology currently available and enhancement of such resources shall be achieved where practicable.

(viii) Prevention of health and safety and fire hazards. Fire hazards and other conditions which constitute a hazard to the health and safety of the public shall be avoided. Combustible materials shall be compacted, buried, disposed or otherwise treated to prevent contamination of groundwater and to prevent sustained combustion.

(2) Casing and sealing of underground openings.

Each exploration hole, other drillhole or borehole, well, and other exposed underground opening which has been identified for use to return coal processing waste or water to underground workings, or to be used to monitor groundwater conditions, shall be temporarily sealed until actual use.

(iii) Temporary sealing of underground mine entries. Each underground mine entry which is temporarily inactive, but has a further projected useful service, shall be protected by barricades or other covering devices, fenced, and posted with signs, to prevent access into the entry and to identify the hazardous nature of the opening.

(3) Standards for permanent impoundments. Permanent impoundments shall meet the following standards:

(i) The quality of the impounded water shall be suitable on a permanent basis for its intended use, and discharge of water from the impoundment shall not degrade the quality of receiving waters to less than the water quality standards established pursuant to applicable State and Federal laws.

(ii) The level of water shall be sufficiently stable to support the intended use.

(iii) Adequate safety and access to the impounded water shall be provided for proposed water users.

(iv) Water impoundments shall not result in the diminution of the quality or quantity of water used by adjacent or surrounding landowners for agricultural, industrial, recreational, or domestic uses.
