No person(s) shall discharge or cause to be discharged any unpolluted
water, such as stormwater, groundwater, roof runoff, subsurface drainage or
cooling water, to any sewer.
Stormwater and all other unpolluted drainage shall be discharged to
storm sewers or to a natural outlet approved by the Sewer Inspector and other
regulatory agencies. Unpolluted industrial cooling water or process water
may be discharged, on approval of the Sewer Inspector, to a storm sewer or
natural outlet upon application for and receipt of a state pollutant discharge
elimination system permit.
No person(s) shall discharge or cause to be discharged any of the following-prescribed
waters or wastes to any public sewers:
A.
Any gasoline, benzene, naphtha, fuel oil or other flammable
or explosive liquid, solid or gas.
B.
Any waters containing toxic or poisonous solids, liquids
or gases or oxygen-demanding pollutants (BOD, etc.) in sufficient quantity,
either singly or by interaction with other wastes, to injure or interfere
with any waste treatment process, constitute a hazard to humans or animals,
create a public nuisance or create any hazard in the receiving waters of the
wastewater treatment plant.
C.
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 wastewater works.
D.
Solid or viscous substances in such quantities or of
such size as to be capable of causing obstruction to the flow in sewers or
other interference with the proper operation of the wastewater facilities,
such as but not limited to ashes, bones, cinders, sand, mud, straw, shavings,
metal, glass, rags, feathers, tar, plastics, wood, underground garbage, whole
blood, paunch manure, hair and fleshings, entrails, and paper dishes, cups,
milk containers, etc., either whole or ground by garbage grinders.
E.
Wastewater having a temperature higher than 104º
F. (40º C.).
F.
Waters or wastes containing substances which are not
amenable to treatment or reduction by the wastewater treatment processes employed
or are amenable to treatment only to such degree that the wastewater treatment
plant effluent cannot meet the requirements of other agencies having jurisdiction
over discharge to the receiving waters.
The following-described substances, materials, waters or wastes shall
be limited in discharges to municipal systems to concentrations or quantities
which will not harm either the sewers, wastewater treatment process or equipment,
will not have an adverse effect on the receiving stream or will not otherwise
endanger lives, limb or public property or constitute a nuisance. The Sewer
Inspector may set limitations lower than the limitations established in the
regulations below if in his opinion such more severe limitations are necessary
to meet the above objectives. In forming his opinion as to the acceptability,
the Sewer Inspector will give consideration to such factors as the quantity
of subject waste in relation to flows and velocities in the sewers, materials
of construction of the sewers, the wastewater treatment process employed,
capacity of the wastewater treatment plant, degree of treatability of the
waste in the wastewater treatment plant and other pertinent factors. The limitations
or restrictions on materials or characteristics of waste or wastewaters discharged
to the sanitary sewer, which shall not be violated without approval of the
Sewer Inspector, are as follows:
A.
Wastewater containing more than 25 milligrams per liter
of petroleum oil, nonbiodegradable cutting oils or products of mineral oil
origin.
B.
Wastewater from industrial plants containing floatable
oils, fat or grease.
C.
Any garbage that has not been properly shredded, as the term is defined in § 124-2A. Garbage grinders may be connected to sanitary sewers from homes, hotels, institutions, restaurants, hospitals, catering establishments or similar places where garbage originates from the preparation of food in kitchens for the purpose of consumption on the premises or when served by caterers.
D.
Any waters or waste containing the following toxic substances
shall not be discharged into the wastewater facility unless the levels of
concentration are within the effluent concentrational limits, in milligrams
per liter, as set forth below:

E.
Any waters or wastes containing odor-producing substances
exceeding limits which may be established by the Sewer Inspector.
F.
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Sewer Inspector in
compliance with applicable state or federal regulations.
G.
Quantities of flow or concentrations, or both, which
constitute a slug as defined herein.
H.
Any water or wastes which, by interaction with other
water or wastes in the public sewer system, release obnoxious gases, form
suspended solids which interfere with the collection systems or create a condition
deleterious to structures and treatment processes.
All waters or wastes discharged or proposed to be discharged into the
public sewers by an industry subject to a national categorical pretreatment
standard must be in compliance with the applicable standard.
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 § 124-28 of this article and which, in the judgment of the Sewer Inspector, may have a deleterious effect upon the wastewater facilities, processes, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Sewer Inspector may:
(1)
Reject the wastes.
(2)
Require pretreatment to an acceptable condition for discharge
to the public sewers.
(3)
Require control over the quantities and rates of discharge.
(4)
Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 124-34 of this article, except that acceptance of payments in lieu of pretreatment necessary to achieve compliance with categorical pretreatment standards or prohibited discharge standards is prohibited.
B.
When considering the above alternatives, the Sewer Inspector
shall give consideration to the economic impact of each alternative on the
discharger. If the Sewer Inspector permits the pretreatment or equalization
of waste flows, the design and installation of the plants and equipment shall
be subject to the review and approval of the Sewer Inspector.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Town, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts, as specified in § 124-28B, 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 Sewer Inspector and shall be located so as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal, which are subject to review by the Sewer Inspector. Any removal and hauling of the collected materials not performed by the owner's personnel must be performed by currently licensed waste disposal firms.
A.
Where applicable, categorical industries will be required
to comply with national categorical pretreatment standards.
B.
Where pretreatment or flow-equalizing facilities are
provided or required for any waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner(s) at his expense.
A.
When required by the Sewer Inspector, the owner(s) of
any property serviced by a building sewer carrying industrial wastes shall
install a suitable structure, together with such necessary meters and other
appurtenances in the building sewer, to facilitate observation, sampling and
measurement of the wastes.
B.
Such structure, when required, shall be accessibly and
safely located and shall be constructed in accordance with plans approved
by the Town Inspector. The structure 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.
The Sewer Inspector may require a user of sewer services to provide
information needed to determine compliance with this chapter. These requirements
may include:
A.
Wastewater discharge peak rate and volume over a specified
time period.
B.
Chemical analyses of wastewater.
C.
Information on raw materials, processes and products
affecting wastewater volume quality.
D.
Quantity and disposition of specific liquid, sludge,
oil, solvent or other materials important to sewer use control.
E.
A plot plan of sewers on the user's property showing
sewer and pretreatment facility location.
F.
Details of wastewater pretreatment facilities.
G.
Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
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.
Sampling methods, location, times, durations and frequencies are to be determined
on an individual basis, subject to approval by the Sewer Inspector.
A.
If for any reason a facility does not comply with or
will be unable to comply with any prohibition or limitations in this chapter,
the facility responsible for such discharge shall take immediate corrective
action to prevent continued harm to the treatment works and shall immediately
notify the Sewer Inspector so that additional corrective action may be taken
to protect the treatment works. In addition, a written report addressed to
the Town Board, detailing the date, time and cause of the accidental discharge,
the quantity and characteristics of this discharge, corrective action taken
at the time of the discharge and action taken to prevent future discharges,
shall be filed by the responsible person within five days of the occurrence
of the noncomplying discharge.
B.
Such notification will not relieve users from liability
for any expense, loss or damage to the sewer system, treatment plant or treatment
process or for any penalties imposed on the Town Board.
No statement contained in this article shall be construed as preventing
any special agreement or arrangement between the Town of Warwick and any industrial
concern whereby an industrial waste of unusual strength or character may be
accepted by the Town of Warwick for treatment; however, no special agreements
or arrangements shall be made that would circumvent categorical pretreatment
standards or prohibited discharges.
