(b) (1) Notwithstanding anything contained in 15 RCNY § 19-04(a) above, when the volume of a single toxic discharge or the combined toxic discharges of a group of establishments within a single drainage area is large enough, in the opinion of the Commissioner, to create unacceptable total concentrations of a toxic substance either in the influent entering a sewage treatment plant or in the receiving waters, the Commissioner may by order impose more stringent concentration limits than those listed in 15 RCNY § 19-04(a), or impose mass limits upon the person or persons so discharging. Conversely, when a toxic discharge is sufficiently diluted or rendered innocuous before reaching a sewage treatment plant or the receiving waters, the Commissioner may, in his or her absolute discretion, grant written permission for discharge concentrations greater than those listed in 15 RCNY § 19-04(a).
(2) The Commissioner may by order impose maximum amounts or concentrations of a toxic substance which may be discharged directly or indirectly to a combined or sanitary sewer from an industrial source notwithstanding that such amounts or concentrations are less than those demanded by other subdivisions of this section or that the substance is not regulated by such subdivisions for that source, provided that such amounts or concentrations are economically achievable by that source as determined by the Commissioner. Within 20 days after service of the Commissioner's determination and order, the person discharging the toxic substance may request a hearing at which evidence may be presented only upon the issue of the economic achievability of the maximum amounts or concentrations of the toxic substance, as imposed by the Commissioner, to be discharged to the combined or sanitary sewer. Following such hearing, the hearing officer designated by the Commissioner shall report his or her findings and recommendations to the Commissioner who, in his or her discretion, may sustain, revoke, or modify the original determination and order. The Commissioner shall, upon his or her decision to sustain or modify the original determination and order, issue a final order to the person discharging the toxic substance to comply with such decision.
(c) Pursuant to § 24-523(e)(2) of the Administrative Code, all pretreatment standards and requirements promulgated pursuant to the Federal Water Pollution Control Act, commonly referred to as the Clean Water Act, as amended, including time limitations for compliance with such standards, monitoring of wastewater and the reporting of the results of such monitoring are hereby incorporated into these regulations and all such reports must also be made to the Commissioner. All sources of pollutants or toxic substances to the combined or sanitary sewers, subject to such pretreatment standards, must discharge wastewaters to the combined or sanitary sewers in conformance with such standards, provided however, that if a more stringent standard is applicable under 15 RCNY § 19-04(a) or (b) or any other section of these Regulations then the more stringent standard shall be controlling.
(2) Bypass of Pretreatment Facilities.
(i) Bypass is prohibited unless:
(A) it is unavoidable to prevent loss of life, personal injury, or severe property damage, no feasible alternatives exist, and the Industrial User submits notification as required by subparagraph (b) of this paragraph; or
(B) it is for essential maintenance to assure efficient operation, it does not cause pretreatment standards or requirements to be violated, and the Industrial User submits notification as required by subparagraph (b) of this paragraph.
(ii) Notification of bypass:
(A) Anticipated bypass. If the Industrial User knows in advance of the need for a bypass, it must submit prior written notice, at least ten days before the date of the bypass, to the Department.
(B) Unanticipated bypass. The Industrial User shall immediately notify the Department by calling 311, and must submit a written notice to the Department within 5 days after the bypass. This report shall specify:
1. a description of the bypass, its cause and duration;
2. whether the bypass has been corrected; and
3. the steps being taken or to be taken to reduce, eliminate and prevent a recurrence of the bypass.
When calling 311 the Industrial User must ask for and record the complaint number for proof of compliance with the notification requirements.

(a) Conditional house connection.
(1) Conditional House Connection Permits are issued under a variety of situations among which the two (2) most common are:
(i) The developer/builder does not have a prospectus at the time house connection permits have to be issued as consequence of a hardship.
(ii) The developer/builder does not have a prospectus which is most likely early on in the construction sequence of his or her building construction, however needs one or several connections to drain the construction site.
(2) The manner in which conditional House Connection Permits are issued is as follows: The Local Office of the Department's Permit Control Section will approve a permit application conditionally by indicating on it that the Certificate of Inspection is not to be released until a prospectus has been secured.
(b) Trailer connections. Basically there are two types of trailer connections:
(1) A construction trailer connection that is necessitated by the construction of a building. Such connection should be tied in with the certification of the site connection proposal and the issuance of the House Connection Permits for such building as follows:
(i) The Plumber requesting the trailer connection should present a copy of the certified site connection proposal with the Permit Application.
(ii) The Local Office will issue a house connection permit subject to the following condition: We will withhold the Certificate of Inspection for at least one of the Buildings House Connections until the plug for the trailer connection is performed.
(2) If the construction trailer is necessitated by the Department of Transportation (or any other Agency's) Capital Project, the plumber should present an original letter from the appropriate agency to the Department indicating:
(i) The number and size of connections needed.
(ii) The duration of the construction operations at the end of which the plumber will plug the trailer connection(s).
(iii) Guarantee from DOT (or any other Agency) that the Plumber will obtain a plug permit(s) at the end of their construction operations to plug the trailer connection(s).
The Local Office will not issue any other trailer connections to the agency in question if it is common knowledge that a job has been completed and there are outstanding open connections.
