No persons shall discharge directly or indirectly
into the City sewer system or into any private sewer drain emptying
into the City sewer system any substances, materials, waters or wastes
in such quantities or concentrations which cause or are capable of
causing, either alone or by interaction with other substances, interference
with the operation of performance of the treatment works or which
pass through the treatment works inadequately treated. No persons
shall discharge the following into the City sewer system:
A. Any liquids, solids or gases which, by reason of their
nature or quantity, are or may be sufficient either alone or by interaction
with other substances to cause fire or explosion or be injurious in
any other way to the treatment works or to the operation of the treatment
works. At no time shall two successive readings on an explosion hazard
meter, at the point of discharge into the system or at any point in
the system, be more than 5% nor any single reading over 10% of the
lower explosive limit (LEL) of the meter. Prohibited materials include
but are not limited to gasoline, kerosene, naphtha, fuel oil, benzene
and any other substances which the City Engineer, the Joint Sewer
Board, the DEC or EPA has notified the user constitute a fire or explosion
hazard to the system.
B. Solid or viscous substances in such quantities or
concentrations which may cause obstruction to the flow in a sewer
or other interference with the operation of the wastewater treatment
facilities, such as but not limited to shredded garbage with particles
greater than 1/2 inch in any dimension, animal guts or tissues, paunch
manure, bone, entrails, lime, stone or marble dust, metal, glass,
straw, solvents, grass clippings, rags, wastepaper, wood, plastics,
tar, asphalt residues, residues from refining or processing of fuel
or lubricating oil, mud or glass grinding or polishing wastes, snow,
ice, any other solid objects, materials, refuse, debris or industrial
treatment residue.
C. Any wastewater having a pH less than 6.0 SU, or greater
than 12.4 SU. Wastewater having a pH greater than 10 SU, but in no
case greater than 12.4 SU, may be discharged to the POTW only if authorized
upon application and issuance of a wastewater discharge permit and
if the manager of the wastewater programs makes a determination that
the wastewater will not pose a hazard to or harm the POTW or treatment
plant workers, will not cause pass-through or interference and will
not raise the costs of operating the POTW. The manager of the wastewater
programs may revoke at any time authorization for pH discharges from
10 to 12.4 SU if they prove to be detrimental to the POTW.
[Amended 12-19-2000 by L.L. No. 11-2000]
D. Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants, to
injure or interfere with any wastewater treatment process, constitute
a hazard to humans or animals, create a toxic effect in the receiving
waters of the treatment works or to exceed the limitation set forth
in a categorical pretreatment standard. A toxic pollutant shall include
but not be limited to any pollutant identified pursuant to Section
307(a) of the federal Act.
E. Any noxious or malodorous liquids, gases or solids
which, either singly or by interaction with other wastes, are sufficient
to create a public nuisance or hazard to life or are sufficient to
prevent entry into the sewers for their maintenance and repair.
F. Any substance in such quantities or concentrations
which may cause the treatment works effluent or any other product
of the treatment works, such as sludges or scums, to be unsuitable
for reclamation and reuse or to interfere with the reclamation process
where the treatment works is pursuing a reuse and reclamation program.
In no case shall a substance discharged to the treatment works cause
the treatment works to be in noncompliance with sludge use or disposal
criteria, guidelines or regulations developed under Section 405 of
the federal Act; any criteria, guidelines or regulations affecting
sludge use or disposal developed pursuant to the Solid Waste Disposal
Act, as amended by the Resource Conservation and Recovery Act of 1976,
as amended (42 U.S.C. § 6905 et seq.); or DEC criteria applicable
to the sludge management method being used.
G. Any substance in such quantity or concentration which
will cause the treatment works to violate its SPDES permit.
H. Any wastewater with objectionable color. A color is
objectionable if the Joint Sewer Board determines that it cannot be
adequately removed in the treatment process.
I. Any wastewater having a temperature which will inhibit
biological activity in the treatment plant resulting in interference,
but in no case heated wastewater having a temperature in excess of
150° F. [sixty-five point five degrees Celsius (65.5° C.)]
or in such quantities that the temperature at the introduction into
the treatment plant exceeds 104° F.(40° C.).
J. Any pollutant, including oxygen demanding pollutants
(BOD, etc.) released in a discharge at a flow rate and/or pollutant
concentration which will cause interference with the POTW. In no case
shall a slug load have a flow rate or contain concentrations or quantities
of pollutants that exceed, for any time period longer than 15 minutes
more than five times the average twenty-four-hour concentration, quantities
or flow during normal operation.
K. Any wastewater which causes a hazard to human life
or creates a public nuisance.
L. Foam or other substances in amounts which interfere
with the accuracy or proper functioning of flow measuring or sampling
equipment employed by the City, Joint Sewer Board, DEC or EPA. The
Joint Sewer Board may direct any person discharging into the City
sewer system to add a defoaming agent to his wastewater prior to discharge
through a monitoring facility employed by the Joint Sewer Board. The
defoaming agent shall be added at the furthest point upstream of the
monitoring facility as is necessary and practical to achieve the defoaming
effect.
No person shall discharge or cause to be discharged
any radioactive materials or wastes into the sanitary sewer system
except when:
A. The person is authorized to use radioactive materials
by the DEC or other governmental agency empowered to regulate the
use of radioactive materials.
B. The person is in compliance with all rules and regulations
of all other applicable regulatory agencies.
C. The person holds a valid industrial wastewater discharge
permit which has been issued in accordance with the rules and regulations
of the Board and which expressly permits the introduction of radioactive
materials into the sanitary sewer system.
No person shall discharge substances directly
into a manhole or other opening in a sanitary sewer other than through
an approved building sewer.
No discharger into the City sewer system shall
augment the use of process water or otherwise intentionally dilute
the discharge as a partial or complete substitute for adequate treatment
to achieve compliance with this chapter or the rules and regulations
of the Joint Sewer Board.
[Amended 2-24-2004 by L.L. No. 1-2004]
A. No person shall discharge directly or indirectly into

C. The maximum allowable industrial loading for each parameter identified in Subsection
B of this section shall be distributed by the Joint Sewer Board to industrial users or authorized dischargers by the following protocol:
(1)
At a minimum, each permitted industrial user
shall be guaranteed the de minimus concentration for each parameter.
Industrial users cannot discharge above the de minimus concentration
without permit authorization.
(2)
The Joint Sewer Board may distribute the remaining
75% of the maximum allowable industrial loading to permitted industrial
users or authorized dischargers as a concentration limit based at
the Joint Sewer Board's discretion. All concentration limits allocated
in excess of the de minimus concentration shall be allocated at the
industrial user's maximum permitted flow. In its discretion the Joint
Sewer Board shall consider:
(a)
The need(s) of the industrial user;
(b)
Historical discharge trends;
(c)
Past pollution control efforts of each industrial
user as compared to other industrial users discharging the same substance;
(d)
Potential for growth in the POTW service area;
(e)
The potential for more restrictive regulatory
requirements to be placed on the POTW discharge on sludge disposal
method; and
(f)
Treatabilty of the substance.
(3)
At no time may the Joint Sewer Board distribute a total cumulative amount of any parameter identified in Subsection
B of this section greater than the maximum allowable industrial loading. All allocations shall be made on a concentration basis. No mass-based limits will be granted by the Joint Sewer Board.
(4)
To assure that the maximum allowable industrial loading for each parameter is not violated, the Joint Sewer Board shall reissue industrial wastewater discharge permits to industrial uses annually, during the month of January. At a minimum of every three years, industrial wastewater discharge permits will be issued containing discharge limit concentration (mg/l) for all parameters listed in §
236-608A and §
236-608B. If an industrial wastewater discharge permit does not contain all parameters, industrial users will be notified in writing that they cannot discharge above the de minimus concentration without permit authorization. All permits will indicate the maximum daily flow allowed to be discharged to the City sewer system.
D. Nothing in this chapter shall be construed to relieve
any industrial user from its obligation to comply with applicable
pretreatment standards established pursuant to Section 307 of the
Water Pollution Control Act.
E. Limitations on wastewater strength outlined in §
236-608A through §
236-608C may be supplemented with more stringent limitations when, in the opinion of the Joint Sewer Board:
(1)
The limitations in §
236-608A through §
236-608C of this chapter are not sufficient to protect the operation of the jointly owned wastewater treatment facility, or to protect the treatment works structures or sewers, or to provide adequate safety to the POTW or City employees.
(2)
The limitations in §
236-608A through
236-608C of this chapter are not sufficient to enable the treatment facility to comply with the water quality standards or effluent limitations specified in the POTW's state pollutant discharge elimination system permit (SPDES permit).
(3)
In the event more stringent limitations are
required, all permit holders shall be notified in writing a minimum
of 30 days in advance of the effective date. Permits shall be reissued
at this time with the more stringent limitations.
F. No person shall discharge, directly or indirectly
into the City sewer system, wastewater of unusual strength or character,
as not defined as "normal wastewater," unless authorized by the Joint
Sewer Board.
No person shall break, damage, destroy, uncover,
deface or tamper with any structure, appurtenance or equipment which
is part of the City public sewer system. No person shall tamper with
or render inaccurate any measuring device or mechanism installed pursuant
to any requirement under this chapter.
No person shall knowingly make any false statement
in any application, report or other document required to be filed
pursuant to any provision of this chapter.
