§ 88.305. Hydrologic balance: groundwater monitoring.
(a) Groundwater levels, subsurface flow and the quality of groundwater shall be monitored in a manner approved by the Department to determine the effects of coal refuse disposal activities on the reclaimed lands and on the quantity and quality of groundwater in the permit and adjacent areas.
(b) When coal refuse disposal activities may affect the groundwater systems which serve as aquifers which ensure the hydrologic balance of water use on or off the permit area, groundwater levels and groundwater quality shall be monitored. Monitoring shall include measurements from a sufficient number of sources and chemical analyses of water from aquifers that are adequate to reflect changes in groundwater quality and quantity resulting from those activities. Monitoring shall be adequate to plan for modification of coal refuse disposal activities, if necessary, to prevent, to the extent possible, disturbance of the prevailing hydrologic balance. At a minimum, total dissolved solids or specific conductance corrected to 25°C, pH, acidity, alkalinity, total iron, total manganese, sulfates and water levels shall be monitored and reported to the Department at least every 3 months for each monitoring location.
(c) The Department may require the operator to conduct additional hydrologic tests, including, but not limited to, drilling, infiltration tests, aquifer tests, chemical and mineralogic analyses of overburden and spoil to demonstrate compliance with this section.
(d) 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.
