A.
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.
B.
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 Board of Selectmen.
Industrial cooling water or unpolluted process waters may be discharged, on
approval of the Board of Selectmen, to a storm sewer, combined sewer or natural
outlet. Nothing in this subsection should be construed to grant authority
to the Board of Selectmen to permit any discharge to any storm sewer, combined
sewer or natural outlet unless all required federal and state permits also
have been obtained.
A.
No person shall discharge or cause to be discharged any
of the following described waters or wastes to the POTW or to any public sewer:
(1)
Any wastes or pollutants which cause pass-through or
interference.
(2)
Any pollutants which will create a fire or explosion
hazard in the POTW, including but not limited to waste streams with a closed-cup
flashpoint of less than 140° F. or 60° C., using the test methods
specified in 40 CFR 261.21.
(3)
Any waters or wastes containing toxic or poisonous solids,
liquids or gases in sufficient quantity, either singly or by interaction with
other wastes, which 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.
(4)
Any waters or wastes having a pH lower than 5.0 or having
other corrosive property capable of causing damage or hazard to structures,
equipment, processes and personnel of the POTW. Prior approval from the Board
of Selectmen is required for discharges having a pH lower than 5.5, but in
no case will discharges with a pH lower than 5.0 be permitted.
(5)
Solid or viscous pollutants in quantities or of such
size capable of causing obstruction to the flow in the POTW 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.
(6)
Any liquid or vapor having a temperature higher than
150° F. (65° C.) at the point of discharge to the municipal sewerage
system or having a temperature which will result in interference at the POTW
treatment plant by inhibiting biological activity, but in no case any discharge
containing heat in such quantities which will result in the temperature at
the POTW treatment plant exceeding 104° F. (40° C.).
(7)
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.
(8)
Water or wastes containing petroleum oil, nonbiodegradable
cutting oil or products of mineral oil origin in amounts that will cause interference
or pass-through.
(9)
Pollutants which will result in the presence of toxic
gases, vapors or fumes within the POTW in a quantity that may cause acute
worker health and safety problems.
(10)
Any trucked or hauled pollutants, except at discharge
points designated by the POTW, or without a valid discharge permit or in violation
thereof.
(11)
Materials which exert or cause unusual volume of flow
or concentration of wastes constituting slugs as defined herein.
(12)
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, or which are in violation of any requirement
of a permit issued under these rules and regulations.
B.
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 Board of Selectmen, 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, public
property or constitute a nuisance. In forming its opinion as to the acceptability
of these wastes, the Board of Selectmen 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 sewers, nature of the sewage
treatment process, capacity of the sewage treatment plant, degree of treatability
of wastes in the sewage treatment plant and other pertinent factors. The substances
prohibited are:
(1)
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 Board of Selectmen.
(2)
Any waters or wastes containing strong acid iron pickling
wastes or concentrated plating solutions, whether neutralized or not.
(3)
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 which may
be established by the Board of Selectmen for such materials.
(4)
Any waters or wastes containing phenols, or other taste-
or odor-producing substances, in such concentrations exceeding limits which
may be established by the Board of Selectmen 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.
(5)
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Board of Selectmen
in compliance with applicable state or federal regulations.
(6)
Any waters or wastes having a pH in excess of 9.5.
(7)
Materials which exert or cause:
(a)
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).
(b)
Excessive discoloration (such as, but not limited to,
dye wastes and vegetable tanning solutions).
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 § 256-16B of this article and which, in the judgment of the Board of Selectmen, may have a deleterious effect upon the sewage works, process, equipment or receiving waters or which otherwise create a hazard to life or constitute a public nuisance, the Board of Selectmen may:
B.
If the Board of Selectmen 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 Board of Selectmen
and subject to the requirements of all applicable codes, ordinances and laws.
Grease, oil and sand interceptors shall be provided when, in the opinion
of the Board of Selectmen, 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 Board of Selectmen and shall be located
so 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 Board of Selectmen, the owner of any property serviced
by a building sewer carrying industrial wastes shall install a suitable control
manhole or other sampling location, together with such necessary meters and
other appurtenances, to facilitate observation, sampling and measurement of
the wastes. Such manhole or other sampling location, when required, shall
be accessible and safely located and shall be constructed in accordance with
plans approved by the Board of Selectmen. The manhole or other sampling location,
as well as meters and other appurtenances, shall be installed by the owner
at his expense and shall be maintained by him/her so as to be operable and
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 conducted using
the methods and procedures in 40 CFR Part 136. If no method is listed for
a given parameter, the Director of Public Works shall specify acceptable methods.
A.
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 pHs
must be determined from periodic grab samples).
B.
All industries discharging into a public sewer shall
perform such monitoring of their discharges as the Board of Selectmen 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 Board of Selectmen. Such
records, including records of all monitoring activities and results, whether
or not such monitoring was required, shall be made available upon request
for inspection and copying by the Board of Selectmen and to other agencies
having jurisdiction over discharges to the receiving waters. Records shall
be maintained for a minimum of three years. This period shall be extended
during the course of unresolved litigation or when requested by the POTW or
agency 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 or character may be accepted
by the town for treatment, subject to payment therefor by the industrial concern
and subject to compliance with applicable federal and state discharge requirements.
No person shall maliciously, willfully or negligently break, damage,
destroy, uncover, deface or tamper with any structure, appurtenance or equipment
which is a part of the sewage works. Any person violating this provision shall
be subject to immediate arrest under charge of disorderly conduct.
