by the Superintendent.
[Amended 7-9-1984]
No person shall discharge or cause to be discharged
any of the following described waters or wastes to any public sewer:
A.
Any gasoline, benzene, naphtha, fuel oil or other
flammable or explosive liquid, solid or gas.
B.
Any waters or wastes containing toxic or poisonous
solids, liquids or gases in sufficient quantity, either singly or
by interaction with other wastes, to injure or interfere with any
sewage treatment process, constitute a hazard to humans or animals,
create a public nuisance or create any hazard in the receiving waters
of the sewage treatment plant.
C.
Solid or viscous substances in quantities or of such
size capable of causing obstruction 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, unground garbage, whole
blood, paunch manure, hair and fleshings, entrails and paper dishes,
cups, milk containers, etc., either whole or ground by garbage grinders.
No person shall discharge or cause to be discharged
any substances, materials, waters or wastes if it appears likely,
in the opinion of the Superintendent, that such substances, materials,
water or wastes can harm either the sewers, sewage treatment process
or equipment, have an adverse effect on the receiving stream or can
otherwise endanger life, limb or public property or constitute a nuisance.
In forming this opinion as to the acceptability of these substances,
materials, waters or 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. This prohibition
shall include but not be limited to the following:
A.
Any liquid or vapor having a temperature in excess
of 140° F., unless the Town requires a lower temperature limit
to ensure that the temperature of influent wastewater at the Town's
wastewater treatment works does not exceed 104° F.
[Amended 1-21-1986 by TOR-85-4]
B.
Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, in excess of 100 milligrams per liter
or containing substances which may solidify or become viscous at temperatures
between 32° and 150° F. (0° and 65° C.).
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 Superintendent.
D.
Any waters or wastes containing strong acid, iron,
pickling wastes or concentrated plating solutions, whether neutralized
or not, unless heavy metals and other sludge have been adequately
removed from said wastes in the opinion of the Superintendent.
E.
Any waters or wastes containing iron, chromium, copper,
zinc and similar objectionable or toxic substances; or wastes exerting
an excessive chlorine requirement, to such degree that any such material
received in the composite sewage at the sewage treatment works exceeds
the limits established 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 or 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 9.6
or any waters or wastes having a pH lower than 5.5, or having any
other corrosive property capable of causing damage or hazard to structures,
equipment and personnel of the sewage works.
I.
Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids (such
as but not limited to fuller's earth, lime slurries and 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 BOD, chemical 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 degree that the
sewage treatment plant effluent cannot meet the requirements of other
agencies having jurisdiction over discharge to the receiving waters.
A.
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters or wastes contain the substances or possess the characteristics enumerated in § 175-39 of this article, 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.
If the Superintendent permits the pretreatment or
equalization of waste flow, the design and installation of the plants
and equipment shall be subject to the review and approval of the Superintendent,
and subject to the requirements of all applicable codes, ordinances
and laws.
Grease, oil and sand interceptors will be provided
when, in the opinion of the Superintendent, 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 not be required for private living
quarters or dwelling units. All interceptors shall be of a type and
capacity approved by the Superintendent and shall be located as to
be readily and easily accessible for cleaning and inspection.
Where preliminary treatment or flow-equalizing
facilities are provided for any waters or wastes, they shall be maintained
continuously in satisfactory and effective operation by the owner
at his expense.
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.
A.
All measurements, tests, and analyses of the characteristics
of water 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 premises 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.
B.
All industries discharging into a public sewer shall
perform such monitoring of their discharges as the Superintendent
and/or other duly authorized employees of the Town may reasonably
require, including installation, use and maintenance of monitoring
equipment, keeping records and reporting the results of such monitoring
to the Superintendent. Such records shall be made available upon request
by the Superintendent to other agencies having jurisdiction over discharges
to the receiving waters.
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the Town and any industrial concern whereby an industrial waste of
unusual strength of character may be accepted by the Town for treatment,
subject to payment therefor, by the industrial concern. Such agreement
may not waive pretreatment standards (local and categorical), unless
such a waiver is granted by mechanism established under the General
Pretreatment Regulations. Prohibited discharge standards may not be
waived under any circumstances.
No septic tank solids shall be discharged into
the Town's sewage works. All septic tank waste shall be discharged
at a designated location at the Bondi Island Treatment Plant.
[Added 7-9-1984]
No waters contaminated with silts or sediment
shall be discharged into a watercourse, detention area or storm drain.
