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.
A.
All measurements, tests and analyses of the characteristics of waters
and wastes to which reference is made in this chapter are to 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 are to 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 required, the control manhole
is considered to be the nearest downstream manhole in the public sewer
to the point at which the building sewer is connected.
B.
Sampling is to 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 are determined from periodic grab samples.
C.
All industries discharging into a public sewer must perform such
monitoring of their discharge 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 are to be made available upon request by the Superintendent
to other agencies having jurisdiction over discharges to the receiving
waters.
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.
A.
If any waters or wastes are discharged or are proposed to be discharged into the public sewers, which waters contain the substances or possess the characteristics enumerated in § 13.1.2.5, 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:
(1)
Reject the waters or pollutants;
(2)
Require pretreatment to an acceptable condition for discharge
to the public sewers; and/or
(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 under the provisions of § 13.1.2.1.
(5)
When considering the above alternatives, the Superintendent
must give consideration to the economic impact of the last alternative
on the discharge.
B.
If the Superintendent permits the pretreatment or equalization of
waste flows, the design and installation of the plants and equipment
is to be subject to the review and approval of the Superintendent
and subject to the requirements of all applicable codes, regulations,
laws and municipal waste discharge permit (NPDES).
C.
The Superintendent may require a user of sewer services to provide
information needed to determine compliance with this chapter. These
requirements include:
(1)
Wastewater discharge peak rate and volume over a specific time
period;
(2)
Chemical analysis of the wastewater;
(3)
Information on raw materials, processes and products affecting
wastewater volume and quality;
(4)
Quantity and disposition of specific liquid, sludge, oil, solvent
or other materials important to sewer use control;
(5)
A plot plan of the user's property showing sewers and pretreatment
facility locations; and
(6)
Details of systems to prevent and control losses of materials
through spills to the municipal sewer.
D.
The Town will develop and the Superintendent will enforce pretreatment
regulations for existing and new sources of pollution that are discharged
into the municipally owned wastewater treatment facilities, as set
forth in Title 40, Chapter I, Part 129 and Part 403 of the rules of
the United States Environmental Protection Agency.[1]
A.
Grease, oil and sand interceptors are to be provided when, in the
opinion of the Superintendent, 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
may not be required for private living quarters or dwelling units.
All interceptors are to be of a type and capacity approved by the
Superintendent and located as to be readily and easily accessible
for cleaning and inspection.
B.
In maintaining these interceptors, the owner(s) are responsible for
the proper removal and disposal by appropriate means of the captured
material and must maintain records of the dates and means of disposal,
which are subject to review by the Superintendent. Any removal and
hauling of collected materials not performed by the owner's personnel
must be performed by currently licensed waste disposal firms.
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.
A.
When required by the Superintendent, the owner of any property serviced
by a building sewer carrying industrial wastes must install a suitable
structure, together with such necessary meters and other appurtenances,
in the building sewer to facilitate observation, sampling and measurement
of the wastes.
B.
Such structure, when required, must be accessibly and safely located
and constructed in accordance with plans approved by the Superintendent.
The structure must be installed by the owner at the owner's expense,
and maintained by such owner so as to be safe and accessible at all
times.
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
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.
