[Amended 11-7-1996 by L.L. No. 15-1996]
The admission into the public sewers of any waters or wastes having pollutant concentrations exceeding those of normal sanitary sewage as given in § 514-32K, containing any quantity of substances described in § 514-32 or having an average daily flow rate greater than 2% of the average daily wastewater flow which enters the wastewater treatment plant shall be subject to the review and approval of the enforcement officer. When necessary, the user discharging such wastes shall be granted an industrial wastewater permit to require reduction of the concentration of constituents to the normal levels given in § 514-32K, reduce objectionable characteristics to the maximum limits provided for in § 514-32 or control the quantities and rates of discharge of such waters or wastes.
All industrial establishments contributing (or intending to contribute) industrial wastes to the public sewer shall comply with the following provisions:
A. 
Any industrial user subject to the National Categorical Pretreatment Standards (40 CFR Chapter I, Subchapter N, Parts 405 to 471) must comply with such pretreatment standards as well as any more stringent pretreatment standards necessitated by local conditions. The categorical pretreatment standards found at 40 CFR Chapter I, Subchapter N, Parts 405 to 471, are hereby incorporated into these regulations.
[Amended 11-7-1996 by L.L. No. 15-1996; 10-5-1999 by L.L. No. 11-1999]
B. 
Disposal into the public sewers of any pollutant by any person is unlawful except in compliance with federal standards promulgated pursuant to the Act.
[Amended 11-7-1996 by L.L. No. 15-1996]
C. 
Permission shall be granted to authorized employees of USEPA and NYSDEC to enter properties of contributing industries for the purpose of inspections, observation, measurement, sampling and testing.
D. 
Written approval by the enforcement officer is required for all new discharges from industrial users added to the City's POTW. The enforcement officer reserves the right to:
[Amended 11-7-1996 by L.L. No. 15-1996]
(1) 
Deny or condition new or increased contribution of wastes or changes in waste characteristics to the POTW where such contributions do not meet applicable pretreatment standards or where such contributions would cause the POTW to violate its SPDES permit;
(2) 
Require an industrial user to obtain an industrial wastewater discharge permit as specified in § 514-46;
(3) 
Require the development of a schedule of compliance for industrial users for the installation of technology required to meet pretreatment standards and requirements;
(4) 
Require the industrial user to submit to the City self-monitoring reports; and
(5) 
Require the industrial user, either new or existing, to complete a questionnaire relating to their industrial waste discharge.
Information submitted by industrial users may be treated as confidential, as described in § 514-52.
E. 
Pursuant to 40 CFR 403.8(f)(1)(i) and 403.12(j), all industrial users shall provide prior notification to the enforcement officer of any new or changed discharges prior to the commencement of such discharge.
[Added 10-5-1999 by L.L. No. 11-1999]
F. 
Pursuant to 40 CFR 403.12(p), all industrial users must notify the enforcement officer, the New York State Department of Environmental Conservation and the USEPA, Regional Waste Management Division Director, in writing, of any discharge which would be considered a hazardous waste under 40 CFR 261 if disposed of in a manner other than to the POTW.
[Added 10-5-1999 by L.L. No. 11-1999]
[Amended 11-7-1996 by L.L. No. 15-1996]
All significant industrial users and other industrial users whose industrial waste discharge has or may cause interference or pass-through shall install and maintain suitable monitoring stations on their industrial waste discharges to facilitate observation, sampling and measurement of the wastes. The enforcement officer shall require that such monitoring stations include equipment for the continuous measurement and recording of the wastewater flow rate and for the sampling of the wastewater at intervals of time. Such stations shall be accessibly and safely located, and the industrial users shall allow immediate access to the stations by the enforcement officer or his designated representatives. If the industrial user discharges via more than one sewer lateral, the enforcement officer may require the installation and maintenance of separate monitoring stations on each lateral.
When preliminary treatment, flow-equalizing facilities or monitoring stations are provided for any waters or wastes, they shall be constructed and maintained continuously in satisfactory and effective operation by the owner at his expense. Where an industrial user has such treatment, equalization or monitoring facilities at the time these regulations are enacted, the enforcement officer shall have the power to approve or disapprove of the adequacy of such facilities. Where construction of new or upgraded facilities for treatment, equalization or monitoring are required, plans and specifications prepared by a licensed professional engineer for such facilities shall be submitted to the enforcement officer.
All measurements, tests and analyses of the characteristics of waters and wastes required in any section of this chapter shall be carried out in accordance with the most recent edition of Standard Methods for the Examination of Water and Wastewater and in accordance with regulations promulgated by the USEPA in 40 CFR 136, Guidelines Establishing Test Procedures for the Analysis of Pollutants. Such samples shall be taken at the approved monitoring stations described in § 514-36, if such stations exist. If an approved monitoring station is not required, samples shall be taken from another manhole or other structure on the industrial sewer lateral before discharge to the public sewer. Unless specifically requested otherwise or unless specifically not allowed in federal regulations, samples shall be gathered as flow-weighted composite samples made up of individual samples taken not less than once per hour for a period of time equal to the duration of industrial waste discharge during daily operations.
[Amended 11-7-1996 by L.L. No. 15-1996]
A. 
Each user shall provide for protection from accidental or slug discharges of prohibited materials or of materials in volumes or concentrations exceeding limitations of this chapter or of an industrial wastewater permit. Detailed plans and procedures to provide for this protection shall be submitted to the enforcement officer when so requested. Users shall immediately notify the enforcement officer of the discharge of wastes in violation of this chapter or a permit resulting from breakdown of pretreatment equipment, accidents caused by human error or negligence or mechanical failure or other causes, such as acts of nature, to allow the City to take countermeasures. The enforcement officer shall be notified within five days of such occurrence by a detailed written statement describing the causes of the discharge and the measures being taken to prevent future occurrences.
B. 
When required by the enforcement officer, detailed plans and procedures to prevent accidental or slug discharges shall be submitted to the enforcement officer for approval. These plans and procedures shall be called a spill prevention, control and countermeasure (SPCC) plan. The plan shall address, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any provision of the permit and any pretreatment standard or requirement;
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants (including solvents) and/or measures and equipment for emergency response.
In order that employees of industrial users be informed of City requirements, a notice shall be permanently posted on appropriate bulletin boards within the user's facility advising employees of City requirements and whom to call in case of an accidental discharge in violation of this chapter.
When so requested in advance by an industrial user and when taking a sample of industrial wastewater, City representatives shall gather a sufficient volume of sample so that the sample can be split into two equal volumes. One of the volumes then shall be given to the industry whose wastewater was sampled, and the other shall be kept by the City for its own analysis.
