Section 1819.15  Auger Mining: Hydrological Balance

a)         Auger mining shall be planned and conducted to minimize disturbances of the prevailing hydrologic balance in accordance with the requirements of 62 Ill. Adm. Code 1816.41 and 1816.42.

b)         All auger holes, except as provided in subsection (c), shall be:

1)         Sealed within seventy-two (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 seventy-two (72) hours, the discharge shall be treated commencing within seventy-two (72) hours after completion to meet applicable effluent limitations and water quality standards of subsection (a) until the holes are sealed; and

2)         Sealed with an impervious noncombustible material, within thirty (30) days following completion, 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 Department determines that:

1)         The resulting impoundment of water may create a hazard to the environment or public health or safety such as an unforeseen discharge, and

2)         The drainage from the auger holes will:

A)        Not pose a threat of pollution to surface water in accordance with 62 Ill. Adm. Code 1816.42 and

B)        Comply with the requirements of 62 Ill. Adm. Code 1816.41 and 1816.42.
