Sec. 32. (a) Surface water information shall include the following:

1. (1) The name and location of the surface stream or tributary that will receive drainage from the permit area.
2. (2) The location of any discharge into a surface water body.
3. (3) The location and ownership of all streams, lakes, ponds, springs, and similar surface water bodies within the proposed permit and adjacent areas.

(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:

1. (1) Baseline information on seasonal flow rates.

2. (2) The following baseline water quality parameters:

   1. (A) Total dissolved solids in milligrams per liter or specific conductance corrected to twenty-five (25) degrees Celsius.
   2. (B) Total suspended solids in milligrams per liter.
   3. (C) The pH in standard units.
   4. (D) Required state water quality standards and federal United States Environmental Protection Agency effluent limitations.
   5. (E) Total iron.
   6. (F) Total manganese.
   7. (G) Acidity and alkalinity.
   8. (H) Any additional baseline information required by the director if the other baseline information requirements of this subsection are insufficient to evaluate potential adverse surface water impacts.

(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.

1. (1) The plan required by this subsection shall identify the following:

   1. (A) The surface water quantity and quality parameters to be monitored.
   2. (B) Sampling frequency and procedures.
   3. (C) Site locations.
   4. (D) A description of how the data may be used to determine the impacts of the operation upon the hydrologic balance.

2. (2) At all monitoring locations in the surface water bodies such as streams, lakes, and impoundments that are potentially impacted or into which water will be discharged and at upstream monitoring locations, the following shall be monitored:

   1. (A) Total dissolved solids in milligrams per liter or specific conductance corrected to twenty-five (25) degrees Celsius.
   2. (B) Total suspended solids.
   3. (C) The pH in standard units.
   4. (D) Total iron.
   5. (E) Total manganese.
   6. (F) Flow.
3. (3) For point source discharges, monitoring shall be conducted in accordance with 40 CFR 122, 40 CFR 123, and 40 CFR 434 and as required by the effective National Pollutant Discharge Elimination System (NPDES) permit.
4. (4) The monitoring reports shall be submitted to the director every three (3) months.
5. (5) Any additional monitoring information required by the director if it is necessary to evaluate potential adverse surface water impacts that are not addressed by the other monitoring information requirements of this subsection.
