Current through March 20, 2024
Authority: IC 14-34-2-1
Affected: IC 14-34
Sec. 32.
(a) Surface water information shall include the following:
(b) Surface water information shall include a description of the seasonal variation in water quantity and quality of perennial streams in the permit and adjacent areas as well as those streams or other water bodies in the adjacent area that will receive drainage from the permit area in terms of the following:
(c) If the determination of the probable hydrologic consequences as required by section 47 of this rule indicates that adverse impacts on or off the proposed permit area may occur to the hydrologic balance or that acid-forming or toxic-forming material is present that may result in contamination of ground water or surface water supplies, the director shall require the applicant to provide information supplemental to that required under subsection (b) as necessary to evaluate the probable hydrologic consequences and to plan remedial and reclamation activities. The supplemental information may be based upon drilling, aquifer tests, hydrogeologic analysis of the water-bearing strata, flood flows, or analysis of other water quality or quantity characteristics.
(d) The application shall include a surface water monitoring plan based upon the probable hydrologic consequences determination required under section 47(c) of this rule and the analysis of all baseline hydrologic, geologic, and other information in the permit application. The plan shall provide for the monitoring of parameters that relate to the suitability of the surface water for current and approved postmined land uses and to the objectives for protection of the hydrologic balance as set forth in section 47 of this rule as well as the effluent limitations found at 40 CFR 434.
