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. Any combined sewers shall become separated.
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designated
as 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 or natural outlet
after the discharger has obtained approvals and permits from federal
and state agencies.
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, including but not limited to cyanides
in excess of two milligrams per liter as CN in the wastes as discharged
to the public sewer. However, the discharge of these may be accepted
conditionally by the County Sewer District or Town improvement area
involved unless it will cause the POTW to violate its SPDES permit
or the receiving water quality standards.
C. Any waters or wastes having a pH lower than 5.5, or
having a pH higher than 9.5, 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,
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 and/or the
Director 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 his opinion as to the acceptability of these
wastes, the Superintendent and/or the Director 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 water pollution
control plant and other pertinent factors. The substances prohibited
in the first instance but subject to review by the Superintendent
and/or Director are:
A. Any liquid or vapor having a temperature higher than
150º F. (65º C.) or in such quantities that the temperature
at the treatment works influent exceeds 40º C. (104º F.),
unless the works is designated to accommodate such heat.
B. Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, in excess of 100 milligrams per liter
or containing substances which may solidify or become viscous at temperatures
between 32º F. and 150º F.
C. Any garbage that has not been properly shredded. The
installation and operation of any garbage grinder equipped with a
motor 3/4 horsepower or greater shall be subject to the review and
approval of the Superintendent and/or the Director. Not more than
30% of ground garbage, on the dry basis, shall pass a No. 40 United
States Standard Sieve. Garbage grinders shall not be used for disposal
of:
(1) Plastic, paper products, inert materials or garden
refuse.
(2) Wastes generated in preparation of food not normally
consumed on the premises.
D. Any waters or wastes containing strong acid iron pickling
wastes, or concentrated plating solutions whether neutralized or not.
E. Any water or wastes containing iron, chromium, copper,
zinc and similar objectionable or toxic substances unless their concentration
is reduced to a point that will not adversely affect any of the biochemical,
chemical or other sewage treatment process. The concentration in sewage
of any of the toxic substances shall not exceed the concentrations
judged by the Director to be toxic to biological sewage treatment
processes or to the biota of the receiving waters.
F. Any water or wastes containing phenols or other taste-
or odor-producing substances, in such concentrations exceeding limits
which may be established by the Director 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.
G. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Superintendent
or Director in compliance with applicable state or federal regulations.
H. 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.
I. Any waters or wastes containing a toxic or poisonous
substance, a high chlorine demand or suspended solids in sufficient
quantity to injure or interfere with any sewage treatment process,
constitute a hazard to humans or animals or create any hazard in the
receiving waters or the effluent of the Town sewage treatment plant
or to exceed the limitation set forth in a categorical pretreatment
standard. Such toxic substances shall be limited to the average concentrations
listed hereinafter in the sewage and include but not be limited to
any pollutant identified pursuant to Section 307(a) of the Act (33
U.S.C. § 1292). If concentrations listed are exceeded, individual
establishments will be subject to control in volume and concentration
by the Superintendent (refer to Appendix A).
J. Any substance which may cause the POTW's effluent
or any other product of the POTW, such as residues, sludge or scums,
to be unsuitable for reclamation and reuse or to interfere with the
reclamation process where the POTW is pursuing a reuse with reclamation
program. In no case shall a substance discharged to the POTW cause
the POTW to be in noncompliance with sludge use or disposal criteria,
guidelines or regulations developed under Section 405 of the Act (33
U.S.C. § 1292), and criteria, guidelines or regulations
affecting sludge use or disposal development pursuant to the Solid
Waste Disposal Act, the Clean Air Act, the Toxic Substance Control
Act or state criteria applicable to the sludge management method being
used.
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 §
225-21 of Article
V herein, and which in the judgment of the Superintendent and/or Director 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 and/or Director may:
B. Require pretreatment to an acceptable condition for
discharge to the public sewers;
C. Require control over the quantities and rates of discharge;
and/or
D. Require payment to cover the added cost of handling
and treating the wastes not covered by existing taxes or sewer charges.
Each applicant for a permit to discharge sewage
combined with industrial wastes or other wastes into public sewers
shall fill out and file with the Superintendent an Industrial Sewer
Connection Application as a prerequisite for the consideration of
such a permit. The following is a partial list of information to be
furnished by the applicant:
A. Plot of the property showing accurately all sewers,
drains and house connections.
B. Plans and specifications covering any work proposed
to be performed under the permit.
C. A complete schedule of all process waters and industrial
wastes produced or expected to be produced at said property or premises,
including a description of the character of each waste, the daily
volume and maximum rates of discharge and representative analyses.
D. Detailed plans showing facilities and operating procedures
to provide protection from accidental discharge of prohibited materials
or other wastes from significant contributing industries be submitted
to the Town for review and shall be acceptable to the Town before
construction of the facilities.
E. The name and address of the person or firm who will
be responsible for the performance of the work to be covered by the
permit and the name and address of the person or firm who will be
responsible for operating the facilities in accordance with the terms
and conditions of the permit.
Whenever sewage, industrial wastes or other wastes having characteristics other than prescribed for normal sewage as defined in Article
I herein, or falling within the categories of waste prohibited from public sewers pursuant to these rules and regulations, is discharged into public sewers from any premises, the Superintendent and/or the Director shall have the right to take samples and tests as may be necessary to determine the nature and concentration of such wastes, and shall have the right to reassess his determinations by taking samples and tests at any time or by periodic rechecks without notice to the person discharging such wastes.
A. Samples shall be taken and flow measurements made
normally at the control manhole or manholes.
B. In the event that the requirement for a control manhole
or manholes have been specifically waived, the samples shall be taken
at a point or points to be selected by the Superintendent.
When required by the Superintendent and/or the
Director, and/or operator, or classified as a significant industrial
user, the owner of any property serviced by a building sewer carrying
industrial wastes shall install a suitable control manhole together
with such meters and other appurtenances in the building sewer as
are necessary 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 and/or the Director. 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.
All measurements, tests and analyses of the
characteristics of waters and wastes to which reference is made in
these rules and regulations 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, or upon suitable samples
taken at said control manhole. In the event that no special manhole
has been required, the control manhole shall be considered to be the
nearest suitable one downstream 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.
