No person(s) shall discharge or cause to be
discharged any unpolluted waters such as stormwater, surface water,
groundwater, roof runoff, cellar drainage, water from sump pumps,
water from building drains, 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 conduits as are specifically designed as storm drains or to a
natural outlet approved by the Superintendent. Unpolluted industrial
cooling water or unpolluted process waters may be discharged, on approval
of the Superintendent, to a storm drain or natural outlet, and the
discharge shall comply with all federal, state and local laws, rules,
or ordinances and regulations.
No person(s) 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 which will create a fire
or explosive hazard in the Town's wastewater facilities.
B. Any water or pollutants containing toxic or poisonous
solids, liquids, or gases not listed on Table 1 capable of causing, either singly or by interaction with
other wastes, injury or interference with any waste treatment process,
a hazard to humans or animals, public nuisance, or any hazard in the
Town's facilities.
C. Any waters or wastes having a pH lower than 5.5 or
higher than 9.5 or having any other corrosive property capable of
causing damage or hazard to the Town's facilities and personnel.
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 Town's facilities, such
as, but not limited to, stone, gravel, ashes, cinders, sand, concrete,
paving materials, mud, straw, sticks, plaster, cement, mortar, shavings,
metal, glass, rags, feathers, tar, plastics, wood, improperly shredded
garbage, whole blood, paunch manure, hair, fleshings, entrails, paper
dishes, cups, milk containers, etc., either whole or ground by garbage
grinders.
E. Any waters or pollutants, including oxygen-demanding
pollutants (BOD, etc.), which released in quantities of flow or concentrations
or both constitute a slug as defined herein.
F. Any heated waters or pollutants in amounts which will
inhibit or interfere with biological activity in the Town's wastewater
treatment facilities, but in no case heated waters or pollutants in
such quantities that the temperature at the wastewater treatment facilities
influent exceeds 104º F. (40º C.).
G. Any other materials as determined by the Select Board
to create an adverse impact upon the wastewater facilities.
The following described substances, materials,
wastes or wastewaters, or pollutants discharged to the public sanitary
sewers shall be limited to concentrations or quantities which will
not harm either the public sewers, wastewater treatment process or
other Town facilities, will not have an adverse effect on the receiving
stream, or will not otherwise endanger life, limb, or public property
or constitute a nuisance. The Select Board may set concentration limitations
lower than the limitations established in regulations below if, in
the opinion of the Select Board, much more severe limitations are
necessary to meet the above objectives. In forming his opinion as
to the acceptability, the Superintendent will give consideration to
such factors as the quantity of subject wastes in relation to flows
and velocities in the sewers, the wastewater treatment process employed,
capacity of the wastewater treatment process employed, degree of treatability
of the waste in the wastewater treatment plant, and other pertinent
factors.
A. Liquids or vapors have a temperature higher than 150º
F. (65º C.).
B. Wastewater containing fats, wax, grease, or oils,
whether emulsified or not, in excess of a total of 100 milligrams
per liter or containing substances which may solidify or become viscous
at temperatures between 32º F. and 150º F. (0º C. and
65º C.).
C. Garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of 3/4
horsepower or greater shall be subject to review and approval of the
Town.
D. Waters or wastes containing toxic or poisonous solids,
liquids, or gases in sufficient quantity to injure or interfere with
any sewage treatment process or the effluent of the Town's sewage
treatment facilities. Such toxic substances shall be limited by quantity
or concentration to the average concentrations as established in Table
1 or as established to meet the requirements of the state, federal, or other public agencies of jurisdiction for such discharge to the receiving waters, whichever is lower. At no time shall the hourly concentration exceed three times the average concentration. If concentrations listed are exceeded, individual establishments will be subject to monitoring and control by the Town in volume and concentration of wastes discharged as provided in §
60-37 of this article.
E. Any waters or pollutants containing odor-producing
substances exceeding limits which may be established by the Town.
F. Radioactive wastes or isotopes of half-life or concentrations
as may exceed limits established by the Town in compliance with applicable
state or federal regulations.
G. Quantities of flow or concentrations of any wastewater
constituent or both which constitute a slug as defined herein.
H. Materials which exert or cause:
(1) Unusual concentrations of inert suspended solids,
such as, but not limited to, fuller's earth, lime slurries, or 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 requirement
in such quantities as to constitute a significant load on the Town's
treatment facilities.
(4) Unusual volume of flow or concentration of wastes
constituting organic wastes.
I. Boiler blow-offs or sediment traps.
J. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment process
employed or are amenable to treatment only to such a degree that the
sewage treatment facility effluent cannot meet the requirements of
other agencies having jurisdiction over discharge to the receiving
waters.
K. Any water or pollutant which, by interaction with
other water or pollutants in the public sewer system, releases obnoxious
gases or forms suspended solids which interfere with, or create a
condition deleterious to, the Town's facilities and operation.
L. Any other materials as determined by the Select Board
to create an adverse impact upon the wastewater facilities.
No industrial sludges from septic tanks, cesspools,
or other receptacles storing organic wastes shall be discharged to
the Town's wastewater facilities.
[Amended 6-11-2003; 6-9-2010]
A. Grease, oil, and sand interceptors shall be provided
when, in the opinion of the Wastewater Treatment Plant Superintendent,
they are necessary for the proper handling of liquid wastes containing
floatable 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 Select
Board and shall be located so as to be readily and easily accessible
for cleaning and inspection.
B. In maintaining these interceptors, the owner(s) shall
be responsible for the proper removal and disposal by legal and environmentally
safe methods of the captured material and shall maintain records of
the date, name of hauler, quantity hauled, and means of disposal.
Signed copies of these records shall be submitted every year to the
Select Board. Any removal and hauling of the collected materials shall
be performed by state-licensed waste disposal firms.

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 Select Board, the owner
of any property serviced by a building sewer into which industrial
wastewaters are discharged shall install a suitable control manhole,
together with such necessary monitoring equipment and other appurtenances
to facilitate observation, sampling and measurement of the wastewaters
in the building sewer. Such manholes and equipment, when required,
shall be safely and accessibly located and shall be constructed in
accordance with plans reviewed by the Superintendent. 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. The owner
shall, if required by the Select Board, perform flow measurements
and analyses of the wastewaters at his expense.
The Select Board may require a user of sewer
services to provide information needed to determine compliance with
this chapter. The requirements may include:
A. Wastewater discharge peak rate and volume over a specified
time period;
B. Chemical analyses of wastewater performed by a laboratory
that satisfactorily participates in the United States Environmental
Protection Agency (USEPA) Water Pollution Series of Performance Evaluations;
C. Information on raw materials, processes, and products
affecting wastewater volume and quality;
D. Quantity and disposition of specific liquid, sludge,
oil, solvent, or other materials important to sewer use control;
E. A plot plan of the user's property, showing location
of all structures, water lines, storm drainage, sewers and pretreatment
facility location, drawn to a scale determined by the Superintendent;
F. Details of wastewater pretreatment facility design
and construction; and

[Amended 6-12-2024 ATM
by Art. 12]
The Select Board will develop and enforce pretreatment
regulations for existing and new sources of pollution that are discharged
or proposed to be discharged into the municipally owned wastewater
facilities as set forth in 40 CFR 403 of the Final Rules of the United
States Environmental Protection Agency.
The Select Board shall require 45 days' notification
of any new proposed discharge having a daily flow greater than 2%
of the average daily flow of the Town's facilities. In addition, changes
in volume or character of wastewater greater than 20% shall require
said notification.
No statement contained in this article shall
be construed as preventing any special agreement or arrangements 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
or state laws and/or regulations promulgated thereunder and are compatible
with any user charge and industrial cost recovery system in effect.
