§ 1295. Notification of sewage and wastewater discharges
(a) Definitions. Notwithstanding the application of the definitions in section 1251 to the chapter as a whole, as used in this subchapter:
(1) “Collection system” means pipelines or conduits, pumping stations, force mains, and all other facilities used to collect or conduct sewage or stormwater, or both sewage and stormwater.
(2) “Combined sewer overflow” means an untreated or partially treated discharge to waters of the State from a combined sewer system outfall that results from a wet weather storm event.
(3) “Combined sewer system” means a collection system that was designed to convey sewage and stormwater through the same network of pipes to a treatment plant.
(4) “Dry weather flow” means flow in a sanitary sewer or combined sewer system during periods of dry weather.
(5) “Sanitary sewer system” means a collection system that conveys sewage and groundwater entering the collection system through inflow and infiltration to a wastewater treatment facility.
(6) “Separate storm sewer system” means a collection system that is designed to discharge stormwater and groundwater entering the collection system through inflow and infiltration to surface waters.
(7) “Sewage” means domestic, commercial, and industrial wastewater conveyed by a collection system.
(8) “Stormwater” means precipitation and snowmelt that does not infiltrate into soil, including material dissolved or suspended in it.
(9) “Untreated discharge” means:
(A) combined sewer overflows from a wastewater treatment facility;
(B) overflows from sanitary sewers and combined sewer systems that are part of a wastewater treatment facility during dry weather flows, which result in a discharge to waters of the State;
(C) upsets or bypasses around or within a wastewater treatment facility during dry or wet weather conditions that are due to factors unrelated to a wet weather storm event and that result in a discharge of sewage that has not been fully treated to waters of the State; and
(D) discharges from a wastewater treatment facility to separate storm sewer systems.
(10) “Wastewater treatment facility” means a treatment plant, collection system, pump station, and attendant facilities permitted by the Secretary for the purpose of treating sewage.
(b) Public alert. An operator of a wastewater treatment facility or the operator’s delegate shall as soon as possible, but no longer than one hour from discovery of an untreated discharge from the wastewater treatment facility, post on a publicly accessible electronic network, mobile application, or other electronic media designated by the Secretary an alert informing the public of the untreated discharge and its location, except that if the operator or his or her delegate does not have telephone or Internet service at the location where he or she is working to control or stop the untreated discharge, the operator or his or her delegate may delay posting the alert until the time that the untreated discharge is controlled or stopped, provided that the alert shall be posted no later than four hours from discovery of the untreated discharge.
(c) Agency notification.
(1) An operator of a wastewater treatment facility shall within 12 hours from discovery of an untreated discharge from the wastewater treatment facility notify the Secretary and the local health officer of the municipality where the facility is located of the untreated discharge. The operator shall notify the Secretary through use of the Department of Environmental Conservation’s online event reporting system. If, for any reason, the online event reporting system is not operable, the operator shall notify the Secretary via telephone or e-mail.
(2) A notification required by this subsection shall include:
(A) The specific location of each untreated discharge, including the body of water affected. For combined sewer overflows, the specific location of each untreated discharge means each outfall that has discharged during a wet weather storm event.
(B) Except for untreated discharges under subdivision (a)(9)(D) of this section, the date and approximate time the untreated discharge began.
(C) The date and approximate time the untreated discharge ended. If the untreated discharge is still ongoing at the time of reporting, the entity reporting the untreated discharge shall amend the report with the date and approximate time the untreated discharge ended within three business days of the untreated discharge ending.
(D) Except for untreated discharges under subdivision (a)(9)(D) of this section, the approximate total volume of sewage and, if applicable, stormwater that was released. If the approximate total volume is unknown at the time of reporting, the entity reporting the untreated discharge shall amend the report with the approximate total volume within three business days.
(E) The cause of the untreated discharge.
(F) The person reporting the untreated discharge.
(G) Any other information deemed necessary by the Secretary.
(d) Notification of additional discharges. In addition to untreated discharges posted pursuant to subsection (c) of this section, the Secretary shall post a notification of other unpermitted discharges to waters of the State that may pose a threat to human health or the environment and that are identified by the Secretary. The Secretary’s notification shall include the information required under subdivision (c)(2) of this section and shall be posted on the Secretary’s online event reporting system no later than four hours from the discovery of an unpermitted discharge, except that if the unpermitted discharge is discovered between the hours of 9:00 p.m. and 5:00 a.m., the Secretary shall post the notification no later than 10:00 a.m. of that morning. The Secretary’s notification shall identify the potential threat to the public health that may be posed by recreating in the waters where the unpermitted discharge occurred.
(e) Signage.
(1) Each combined sewer overflow outfall shall be marked with a permanent sign that identifies the outfall and warns of the potential threat to public health that may be posed by recreating in the waters at the outfall or downstream of the outfall during or after a wet weather storm event. The Secretary shall provide each municipality with a combined sewer overflow two signs for each outfall within the municipality. A municipality shall periodically inspect and maintain each sign marking a combined sewer overflow outfall and shall replace a sign if it is destroyed, removed, or no longer legible.
(2)(A) A municipality shall, within its jurisdiction or other geographic area specified by the Secretary, post temporary signs at public access areas downstream of:
(i) untreated discharges under subdivisions (a)(9)(B)-(D) of this section; and
(ii) other unpermitted discharges posted by the Secretary under subsection (d) of this section.
(B) The signs shall warn of the potential threat to public health that may be posed by recreating in the waters due to the untreated or unpermitted discharge. The signs shall remain in place for 48 hours after the untreated or unpermitted discharge has stopped. (Added 2015, No. 86 (Adj. Sess.), § 1, eff. May 4, 2016.)
