“CSO outfall”, a location at which a combined sewer system is designed to produce a CSO discharge.

"Combined sewer system", a system so designed or constructed as to allow surface runoff to enter the conduit carrying sewage, industrial waste, or other waste.

“Discharge flow data,” measurements consisting of the date and daily flow rate of CSO discharge collected using meters at CSO outfalls and the daily rainfall measured at a proximate location in the same watershed as the outfall.

“Discharge notifications,” reports written in plain language and delivered to registered members of the public by electronic mail to notify them of all CSO discharges that occurred in a watershed in the past 24 hours.   The notification shall state (1) the volume of all CSO discharges, (2) the location of all discharging outfalls and their operating authority, (3) the approximate time and date when each CSO discharge began and ended, (4) the level of treatment of each CSO discharge, and (5) the geographic area that may be affected by its flow or by potential flooding.  Furthermore, the notification shall include the following general information, (1) a list of common primary and secondary contact activities which the department  of environmental protection has identified that the waterway can support in dry conditions,  (2) information about the public health implications of CSO discharges and what recreational activities are impaired under these circumstances, (3) widely applicable precautionary measures that recreational users can take to avoid health risk including, but not limited to, advisories against primary or secondary contact activities within a certain time period of rainfall or CSO discharge events, and (4) a list of all authorities that operate outfalls in the watershed.   Registered notification recipients shall include the two largest circulation newspapers as identified by the department of environmental protection in each watershed containing a CSO outfall, all boards of health as defined in Section 1 of Chapter 111 operated by municipalities in the watershed, and the department of public health.

“Level of treatment”, a description in plain language of the measures taken to remove contaminants from sewage before its discharge at a CSO outfall.  This description should include, but not be limited to, disinfectant procedures undertaken to remove bacteria, filtration to remove solids, and any nutrient removal procedures.

(b) Signage shall be installed at a clearly visible site adjacent to the CSO outfall and any public access point to the waterway which the department of environmental protection determines to be affected by CSO discharges at the CSO outfall.   The department of environmental protection shall promulgate rules and regulations for the content, placement, and maintenance of CSO outfall signage.  This content shall include, but not be limited to, descriptions of the existence of the CSO outfall, associated health risks due to bacterial and chemical contamination following CSO discharges, and appropriate precautions the public should take to ensure safe recreation in and around the waterway.  Furthermore, the signage shall use plain language and include pictographic figures clearly communicating these factors to non-English speakers.  The department of environmental protection shall coordinate with the department of conservation and recreation to administer placement of signage on department of conservation and recreation lands.

(b) The department of environmental protection shall issue an annual watershed CSO discharge report by April 15th of each year to the registered recipients of discharge notifications, which shall include an annual summary report of the previous year’s CSO discharge volumes and frequencies, the operating authorities of all CSO outfalls in the watershed, and the general information included in the discharge notifications.

(c) The department of environmental protection shall have the authority to post any available discharge flow data collected prior to the adoption of the permit requirement to this website.
