[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
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.
The enforcement officer may require information from users concerning the on-site use of substances of concern. Information submitted by the user may be treated as confidential, as discussed in § 514-52.
