(b) All auger holes, except as provided in Paragraph (c) of this section, shall be--
(1) Sealed within 72 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 72 hours, the discharge shall be treated commencing within 72 hours after completion to meet applicable effluent limitations and water-quality standards until the holes are sealed; and
(2) Sealed with an impervious noncombustible material, as contemporaneously as practicable with the augering operation, as approved by the division, if the holes are not discharging water containing acid- or toxic-forming material.
(c) Auger holes need not be sealed with an impervious material so as to prevent drainage if the division determines that--
(1) The resulting impoundment of water may create a hazard to the environment or public health or safety, and
(2) The drainage from the auger holes will--
(i) Not pose a threat of pollution to surface water; and
(ii) Comply with the requirements of 4VAC25-130-816.41 and 4VAC25-130-816.42.
