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 gasses 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, including but not limited to cyanides
in excess of two (2) milligrams per liter (mg/l) as CN in the wastes
as discharged to the public sewer.
C. Any waters or wastes having a pH lower than five point
five (5.5), 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,

excess of five hundred (500) mg/l.
[Added ATM 4-5-1983, Art. 41]
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 waters 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, 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:
A. Any liquid or vapor having a temperature higher than
one hundred fifty degrees Fahrenheit (150° F.) [sixty-five degrees
Celsius (65° C.)].
B. Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, in excess of one hundred (100) mg/l
or containing substances which may solidify or become viscous at temperatures
between thirty-two degrees and one hundred fifty degrees Fahrenheit
(32° and 150° F.) [zero degrees and sixty-five degrees Celsius
(0° and 65° C.)].
C. Any garbage that has not been properly shredded. The
installation and operations of any garbage grinder equipped with a
motor of three-fourths (3/4) horsepower [seventy-six hundredths (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 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.
[Amended ATM 4-5-19883, Art. 41]
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 nine
point five (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.
(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 treatments 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 water.
[Amended ATM 4-5-1983, Art. 41]
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 §
180-21, 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:
(2) Require pretreatment to an acceptable condition for
discharge to the public sewers;
(3) Require control over the quantities and rates of discharge;
and/or
(4) Require payment to cover the added cost of handling
and treating the wastes not covered by existing taxes or sewer charges.
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, bylaws and
laws.
[Amended ATM 4-5-1983, Art. 41]
Garages and other establishments, which are
connected directly or indirectly to the public sewers, shall be provided
with a suitable trap or separator if gasoline or wastes with a high
grease content, or any flammable waste, sand or other harmful ingredients
are used and could possibly de discharged, intentionally or unintentionally,
to the public sewers. All traps or separators shall be of a type and
capacity approved by the Director of the Massachusetts Division of
Water Pollution Control, or his authorized agent, and shall be located
so as to be 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.
[Amended STM 12-15-1975, Art. 2]
A. All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this article 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 provided, the control
manhole shall be determined by the Superintendent.
B. 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 for periodic
grab samples.)
C. 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 water.
