New York Codes, Rules and Regulations › Title 6 - DEPARTMENT OF ENVIRONMENTAL CONSERVATION › Chapter X - DIVISION OF WATER RESOURCES › Subchapter A - GENERAL › Article 2 - CLASSIFICATIONS AND STANDARDS OF QUALITY AND PURITY › Part 703 - Surface Water and Groundwater Quality Standards and Groundwater Effluent Limitations › Section 703.6 - Groundwater effluent limitations for discharges to Class GA waters

Current through Register Vol. 46, No. 28, July 10, 2024
(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.
