Section 87.117. Hydrologic balance: surface water monitoring

(a) In addition to the monitoring and reporting requirements established by the Department under Chapter 92 (relating to National Pollutant Discharge Elimination System permitting, monitoring and compliance), surface water shall be monitored to accurately measure and record the water quantity and quality of the discharges from the permit area and the effect of the discharge on the receiving waters. Surface water shall be monitored for parameters that relate to the suitability of the surface water for current and approved postmining land uses and to the objectives for protection of the hydrologic balance as set forth in § 87.69 (relating to protection of hydrologic balance). At a minimum, total dissolved solids or specific conductance corrected to 25°C, total suspended solids, pH, acidity, alkalinity, total iron, total manganese, sulfates and flow shall be monitored and reported to the Department at least every 3 months for each monitoring location.

(b) The Department may require the operator to conduct monitoring and reporting more frequently than every 3 months, and to monitor additional parameters beyond the minimum specified in this section.
