Section 703.6 - Groundwater effluent limitations for discharges to Class GA waters
(a) The groundwater effluent limitations in Table 3 of subdivision (e) of this section and effluent limitations as established by section 702.16(c)(1) of this Title apply to a discharge from a point source or outlet or any other discharge within the meaning of the Environmental Conservation Law, section 17-0501 that will or may enter the waters of the State. Unless a demonstration is made to the contrary, it shall be presumed that a discharge to the ground or unsaturated zone is a discharge to groundwater. The groundwater effluent limitation is the maximum allowable concentration in micrograms per liter (ug/L), unless otherwise noted.
(b) In addition to the chemical characteristics provided in subdivision (a) of this section, coliform or pathogenic organisms shall not be discharged in amounts sufficient to render groundwaters detrimental to public health, safety or welfare.
(c) The department may establish additional groundwater effluent limitations as set forth in Part 702 of this Title.
(d) The groundwater effluent limitations shall be incorporated in SPDES permits (under Part 750 of this Title) for discharges to groundwaters, where applicable.
