Current through Register Vol. 50, No. 11, November 20, 2024

Section XV-2719 - Ground-Water Monitoring Plan

A. The application shall include a ground-water monitoring plan based upon the PHC determination required under §2523 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 ground water for current and approved post-mining land uses and to the objectives for protection of the hydrologic balance set forth in §2717 It shall identify the quantity and quality parameters to be monitored, sampling frequency and site locations. It shall describe how the data may be used to determine the impacts of the operation upon the hydrologic balance. At a minimum, total dissolved solids or specific conductance corrected to 25 C, pH, total iron, total manganese and water levels shall be monitored and data submitted to the office at least every three months for each monitoring location. The office may require additional monitoring.

B. If an applicant can demonstrate by the use of the PHC 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 which significantly ensures the hydrologic balance within the cumulative impact area, then monitoring of that stratum may be waived by the office.
