No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, uncontaminated
cooling water or unpolluted industrial process waters to any sanitary
sewer.
Stormwater and all other unpolluted drainage shall be discharged
to such sewers as are specifically designated as combined sewers or
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, to a storm sewer, combined 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, 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.
Any waters or wastes having a pH lower than 5.0 or having any other
corrosive property capable of causing damage or hazard to structures,
equipment, and personnel of the sewage works.
D.
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 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, 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 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, materials of construction
of the sewage treatment plant, 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 150° F.
or 65° C.
B.
Any water or waste containing fats, wax, grease, or oils, whether
emulsified or not, in excess of 100 mg/l or containing substances
which may solidify or become viscous at temperatures between 32°
F. 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 hp 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.
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 material.
F.
Any waters or wastes containing phenols or other taste- or odor-producing
substances in 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 discharges 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.
I.
Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids (such as, but not
limited to, Fullers 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, which may cause the effluent limitations of the discharge
permit to be exceeded.
(4)
Unusual volume of flow or concentration of wastes constituting slugs.
J.
Waters and wastes containing substances that 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 contain the substances or possess the characteristics enumerated in § 257-33, 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 flows, 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,
laws and the municipal discharge permit. Further, such pretreatment
installations must be consistent with the requirements of any state
pretreatment permit issued to the industry.
Grease, oil, and sand traps shall 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 traps
shall not be required for private living quarters or dwelling units.
All traps 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.
A.
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.
B.
The manhole shall be installed by the owner at his expense and shall
be maintained by him/her so as to be safe and accessible at all times.
All industries discharging into a public sewer shall perform
such monitoring of their discharge as the Superintendent 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.
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 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.
If 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.
No statement contained in this chapter shall be construed as
preventing any special agreement or arrangement between the Town and
any industrial concern whereby an industrial waste of unusual strength
or character may be accepted by the Town for treatment, subject to
payment therefor by the industrial concern, provided that such agreements
do not contravene any requirements of existing federal laws and are
compatible with any user charge and industrial cost recovery system
in effect.
The waste from any privy, septic tank or cesspool may be deposited
and processed at the Town's sewage treatment plant, provided
that such waste is from property in the Town and is not considered
harmful. The plant operator's permission must be given before
such waste can be discharged into the treatment plant. A test of such
waste, and any treatment to make such waste compatible, shall be made
at the contractor's expense if the plant operator considers the
waste harmful to the plant facilities or operation. The contractor
shall assume all liability to property and persons.
