Sec. 72.
(a) Each
application shall include the following ground water information for the permit
area and the adjacent area:
(1) The location
and extent of each aquifer that may be affected by the mining and the estimated
level of the water table.
(2) The
quality of subsurface water encountered.
(3) The location, usage, and ownership for
the permit and adjacent areas of existing wells, springs, and other ground
water resources.
(4) The estimated
recharge capacity of the ground water system in the permitted area using
available information for such areas or for areas with similar hydrologic
conditions.
(5) The approximate
rates of discharge or usage and depth to the water in the coal seam, and each
water-bearing stratum above and potentially impacted stratum below the coal
seam.
(6) A description of the
seasonal variation in water quantity and water quality in the permit and
adjacent areas as follows:
(A) Baseline
information on seasonal water levels.
(B) The following water quality parameters:
(i) Total dissolved solids in milligrams per
liter or specific conductance corrected to twenty-five (25) degrees
Celsius.
(ii) The pH in standard
units.
(iii) Any required state
water quality standards and federal United States Environmental Protection
Agency effluent limitations.
(iv)
Total iron.
(v) Total
manganese.
(vi) Acidity and
alkalinity.
(vii) Any additional
baseline information required by the director if the other baseline information
requirements of this subsection are insufficient to evaluate potential adverse
ground water impacts.
(b) If the determination of the probable
hydrologic consequences as required by section 85 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 this section as necessary to evaluate the probable hydrologic
consequences and to plan remedial and reclamation activities. The supplemental
information may be based upon any of the following:
(1) Drilling.
(2) Aquifer tests.
(3) Hydrogeologic analysis of the
water-bearing strata.
(4) Flood
flows.
(5) Analysis of other water
quality or quantity characteristics.
(c) The application shall include a ground
water monitoring plan based upon the probable hydrologic consequences
determination required under section 85(c) of this rule and the analysis of all
baseline hydrologic, geologic, and other information in the permit application.
The plan shall provide the following information:
(1) The monitoring of parameters that relate
to the suitability of the ground water for current and approved postmining land
uses and to the objectives for protection of the hydrologic balance set forth
in section 85(a) of this rule.
(2)
The identification of the quantity and quality parameters to be monitored,
sampling frequency, sampling procedures, and site locations.
(3) How the data may be used to determine the
impacts of the operation upon the hydrologic balance.
(4) Specific water parameter information
shall be monitored and data submitted to the director at least every three (3)
months for each monitoring location. The required information shall include, at
a minimum, the following:
(A) Total dissolved
solids in milligrams per liter or specific conductance corrected to twenty-five
(25) degrees Celsius.
(B) The pH in
standard units.
(C) Total
iron.
(D) Total
manganese.
(E) Water
levels.
(5) Any
additional monitoring information required by the director if it is necessary
to evaluate potential adverse ground water impacts that are not addressed by
the other monitoring requirements of this subsection.
(6) If an applicant can demonstrate, by the
use of the probable hydrologic consequences determination and other available
information, that a particular water-bearing stratum in the proposed permit and
adjacent areas is not one which serves as an aquifer that significantly ensures
the hydrologic balance within the cumulative impact area, then monitoring of
that stratum may be waived by the director.
