No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, uncontaminated
cooling water or polluted industrial process waters to any sanitary sewer.
The steam cleaning of automotive or other mechanical equipment over manhole
covers is prohibited, as well as the depositing of wastes from such operation
into the sewer system.
Stormwater and all other unpolluted drainage shall be discharged to
such sewers as are specifically designated as storm sewers or to a natural
outlet approved by the Superintendent. Industrial cooling water or unpolluted
process waters may be discharged, on approval of the Superintendent and in
compliance with the applicable NYSDEC SPDES permit, to a storm sewer or natural
outlet.
No person shall discharge or cause to be discharged any of the following
described waters or wastes to any public sewers:
A.
Any gasoline, benzene, naphtha, fuel oil, mineral oil
or other flammable or explosive liquid, solid or gas.
B.
Any water or wastes containing toxic, malodorous or poisonous
solids, liquid or gases, in sufficient quantity, either singly or by interaction
with other waste, to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals, create a public nuisance, interfere
with the use, reuse, reclamation or disposal of sludge or create any hazard
in the receiving waters of the sewage treatment plan or prevent entry into
sewers for maintenance and repair, including but not limited to cyanides in
excess of 1.2 milligrams per liter as CN in the wastes as discharged to the
public sewer.
C.
Any water or wastes acid and alkaline in reaction having
a pH lower than 6.0, higher than 9.5 or having any other corrosive property
capable of causing damage or hazard to structures, equipment and personnel
of the sewage works. Free acids or alkalies must be neutralized at all times
within the above pH range.
D.
Solid or viscous substances in quantities or of such
size capable of causing destruction to the flow in sewers or other interference
with the proper operation of the sewage works, such as but not limited to
ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers,
tar, plastics, wood, cardboard, beer or distillery slops, lime residues, lime
slurry, chemical residues, paint residues, cannery waste, bulk solids, unground
garbage, whole blood, paunch manure, hair and fleshings, entrails, paper dishes
and cups, milk containers, whey, etc., either whole or ground by garbage grinders.
E.
Any waters or wastes containing suspended solids of such
character and quantity that unusual attention or expense is required to handle
such materials at the sewage treatment plant.
F.
Any stormwater, roof drains, springwater, cistern or
tank overflow, footing drain, discharge from any vehicle washrack or water
motor or the contents of a privy vault, septic tank or cesspool or the discharge
of effluent from any air-conditioning machine or refrigeration unit.
No person shall discharge or cause to be discharged the following described
substances, materials, waters or wastes if it appears likely, in the opinion
of the Superintendent, that such wastes can harm either the sewers or the
sewage treatment process or equipment, have an adverse effect on the receiving
stream or can otherwise endanger life, limb, public property or constitute
a nuisance. In forming his opinion as to the acceptability of these wastes,
the Superintendent will give consideration to such factors as the quantities
of subject wastes in relation to flows and velocities in the sewers, the materials
of construction of the sewers, the nature of the sewage treatment process,
the capacity of the sewage treatment plant, the degree of treatability of
wastes in the sewage treatment plant and other pertinent factors. The substances
prohibited are:
A.
Any liquid or vapor having a temperature higher than
104° F. (40° C.) at the influent to the POTW.
B.
Any water or waste containing fats, wax, grease or oils,
whether emulsified or not, in excess of 50 milligrams per liter or containing
substances which may solidify or become viscous at temperatures between 32°
and 150° F.
C.
Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a motor of
3/4 horsepower (0.76 horsepower metric) or greater shall be subject to the
review and approval of the Plumbing Inspector.
D.
Any waters or wastes containing strong acid iron pickling
wastes, or concentrated plating solutions, whether neutralized or not.
E.

by the Superintendent for such materials.
F.
Any waters or wastes containing phenols or other taste-
or odor-producing substances in such concentrations exceeding limits which
may be established by the Superintendent, as necessary, after treatment of
the composite sewage to meet the requirements of the state, federal or other
public agencies of jurisdiction for such discharge to the receiving waters.
G.
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Superintendent in
compliance with applicable state or federal regulations.
H.
Any waters or wastes having a pH in excess of 9.5 or
less than 6.0.
I.
Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids, such
as but not limited to fullers earth or lime residues, or of dissolved solids,
such as but not limited to sodium chloride and sodium sulfate.
(2)
Excessive discoloration, such as but not limited to dye
wastes and vegetable tanning solutions.
(3)
Unusual biochemical oxygen demand or chlorine requirements
in such quantities as to constitute a significant load on the sewage treatment
works.
(4)
Unusual volume of flow or concentration of wastes constituting
slugs, as defined herein.
J.
Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment processes employed
or are amenable to treatment only to such a degree that the sewage treatment
plant effluent and/or sewage treatment plant sludge cannot meet the requirements
of other agencies having jurisdiction over said sewage treatment plant and
receiving waters.
K.
Waters or wastes that contain the following constituents
equal to or in excess of the limitations set forth in this section:

A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in §§ 252-26 and 252-27, and which, in the judgment of the Superintendent, may have a deleterious effect upon the sewage works, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
B.
The admission into the public sewers of any waters or
wastes having a five-day biochemical oxygen demand greater than 300 parts
per million by weight or containing more than 350 parts per million by weight
of suspended solids or containing more than 15 parts per million of chlorine
demand or containing any quantity of substances having the characteristics
above the previously described limits or having an average daily flow greater
than 2% of the average daily sewage flow of the City shall be subject to the
review and approval of the Superintendent.
C.
Preliminary treatment.
(1)
When necessary, in the opinion of the Superintendent,
the owner shall provide, at his expense, such preliminary treatment as may
be necessary to:
(2)
Plans, specifications and any other pertinent information
relating to proposed preliminary treatment facilities shall be submitted to
the Superintendent for approval and to the Water Resources Commission of the
State of New York, and no construction of such facilities shall be commenced
until said approvals are obtained in writing.
Grease, oil and sand interceptors shall be provided when, in the opinion
of the Plumbing Inspector, they are necessary for the proper handling of liquid
wastes containing grease in excessive amounts or any flammable wastes, sand
or other harmful ingredients, except that such interceptors shall be of a
type and capacity approved by the Plumbing Inspector and shall be located
as to be readily and easily accessible for cleaning and inspection. Grease
and oil interceptors shall be constructed of impervious materials capable
of withstanding abrupt and extreme changes in temperature. They shall be of
substantial construction, watertight and equipped with easily removable covers
which, when bolted in place, shall be gastight and watertight. Proper operation
must be assured by proper maintenance.
Where preliminary treatment or flow-equalizing facilities, including
but not limited to grease, oil and sand interceptors, are provided for any
waters or wastes, they shall be maintained continuously in satisfactory and
effective operation by the owner, at his expense. These facilities shall be
readily accessible and open to inspection by the Plumbing Inspector at any
time.
When required by the Superintendent, the owner of any property serviced
by a building sewer carrying industrial wastes shall install a suitable control
manhole, together with such necessary meters and other appurtenances in the
building sewer to facilitate observation, sampling and measurement of the
wastes. Such manhole, when required, shall be accessibly and safely located
and shall be constructed in accordance with plans approved by the Superintendent.
The manhole shall be installed by the owner at his expense and shall be maintained
by him so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of waters
and wastes to which reference is made in this chapter shall be determined
in accordance with the latest edition of Standard Methods for the Examination
of Water and Wastewater, published by the American Public Health Association,
and shall be determined at the control manhole provided or upon suitable samples
taken at said control manhole. In the event that no special manhole has been
required. the control manhole shall be considered to be the nearest downstream
manhole in the public sewer to the point at which the building sewer is connected.
Sampling shall be carried out by customarily accepted methods to reflect the
effect of constituents upon the sewage works and to determine the existence
of hazards to life, limb and property. (The particular analyses involved will
determine whether a twenty-four-hour composite of all outfalls of a premise
is appropriate or whether a grab sample or samples should be taken. Normally,
but not always, BOD and suspended solids analyses are obtained from twenty-four-hour
composites of all outfalls, whereas pH's are determined from periodic
grab samples.) All samplings will be made by the City or its authorized representative,
and any fee for such services is the sole responsibility of the property owner.
No statement contained in this article shall be construed as preventing
any special agreement or arrangement between the City and any industrial concern
whereby an industrial waste of unusual strength or character may be accepted
by the City for treatment, subject to payment therefor by the industrial concern.
No special agreements shall circumvent Federal Categorical Pretreatment Standards.
Upon the promulgation of the Federal Categorical Pretreatment Standards
for a particular industrial subcategory, the federal standard, if more stringent
than the limitations imposed under this chapter for sources in that subcategory,
shall immediately supersede the limitations imposed under this chapter. The
Superintendent shall notify all affected users of the applicable reporting
requirements under 40 CFR 403.12.
No user shall ever increase the use of process waters or in any way
attempt to dilute a discharge as a partial or complete substitute for adequate
treatment to achieve compliance with the limitations contained in the Federal
Categorical Pretreatment Standards or in any other pollutant-specific limitation
developed by the City or state.
Accidental discharges of any waste or sewage prohibited in §§ 252-26 and 252-27 of this chapter must be reported to the Superintendent immediately. Within five days following an accidental discharge, the user shall submit to the Superintendent a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage or other liability which may be incurred as a result of damage to the sewage works or fishkills or any other damage to person or property; nor shall such notification relieve the user of any fines, civil penalties or other liability which may be imposed by this chapter.
