No statement contained in this article may 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.
No person may 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 without the consent of the Superintendent.
Stormwater and all other unpolluted drainage is to 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 may 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 pollutants containing toxic or poisonous solids, liquids
or gases in sufficient quantity, either singly or by interaction with
other pollutants, to injure or interfere with any wastewater 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 pollutants 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; or
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, bones, 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.
Where pretreatment or flow-equalizing facilities are provided
for any waters or wastes, they must be maintained continuously in
satisfactory and effective operation by the owner at the owner's expense.
No person may 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,
public property or constitute a nuisance. In forming an 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 150° F.
(65° C.);
B. Any water or pollutants containing fats, wax, grease or floatable
oils;
C. Any garbage that has not been properly shredded. The installation
and operation of any garbage grinder equipped with a motor of three-quarter
horsepower (0.76 hp metric) or greater is subject to the review and
approval of the Superintendent;
D. Any waters or pollutants containing strong acid iron-pickling pollutants
or concentrated plating solutions, whether neutralized or not;
E. Any waters or pollutants containing iron, chromium, copper, zinc
and similar objectionable or toxic substances; or pollutants 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 pollutants 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 or jurisdiction for such discharge 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 and 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, fuller's 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; or
(4)
Unusual volume of flow or concentration of wastes constituting "slugs," as defined in §
13.1.1.1.
J. 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; and
K. Wastewater containing more than 25 milligrams per liter of petroleum
oil, nonbiodegradable cutting oils or product of mineral oil origin.
