All users of the POTW will comply with all standards
and requirements of the Act and standards and requirements promulgated
pursuant to the Act, including but not limited to 40 CFR Parts 406
through 471.
A.
No user shall contribute or cause to be contributed,
in any manner or fashion, directly or indirectly, any pollutant or
wastewater which will interfere with the operation or performance
of the POTW. These general prohibitions apply to all such users of
a POTW whether or not the user is subject to national categorical
pretreatment standards, or any other national, state, or local pretreatment
standards or requirements.
B.
Without limiting the generality of the foregoing,
a user may not contribute the following substances to the POTW:
(1)
Any solids, liquids, or gases which, by reason of
their nature or quantity, are or may be sufficient, either alone or
by interaction with other substances, to cause a fire or an explosion
or be injurious, in any way, to the POTW, or to the operation of the
POTW. At no time shall both of two successive readings on a flame-type
explosion hazard meter, at the point of discharge into the system
(or at any other point in the system) be more than 25% nor any single
reading be more than 40% of the lower explosive limit (LEL) of the
meter. Unless explicitly allowable by a written permit, prohibited
materials include, but are not limited to, gasoline, kerosene, naphtha,
benzene, toluene, xylene, ethers, alcohols, carbides, hydrides, and
sulfides, and any other substance which the Town, the state, or the
EPA has determined to be a fire hazard, or hazard to the POTW.
(2)
Solid or viscous substances which may cause obstruction
to the flow in a sewer or otherwise interfere with the operation of
the wastewater treatment facilities. Unless explicitly allowable by
a written permit, such substances include, but are not limited to,
grease, garbage with particles greater than 1/2 inch in any dimension,
animal guts or tissues, paunch manure, bones, hair, hides or fleshings,
entrails, whole blood, feathers, ashes, cinders, sand, spent lime,
stone or marble dust, metal, glass, straw, shavings, grass clippings,
rags, spent grains, spent hops, waste paper, wood, plastics, gas,
tar, asphalt residues, residues from refining or processing fuel or
lubricating oil, mud, or glass or stone grinding or polishing wastes.
(3)
Any wastewater having a pH less than 5.0 or greater
than 10.0, unless the POTW was specifically designed to manage such
wastewater, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment, and/or POTW
personnel.
(4)
Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other pollutants (including
heat), to injure or interfere with any wastewater treatment process,
constitute a hazard to humans or animals, create a toxic effect in
the receiving waters of the POTW, or to exceed the limitation set
forth in a categorical pretreatment standard. A toxic pollutant shall
include, but not be limited to, any pollutant identified pursuant
to Section 307(A) of the Act.
(5)
Any noxious or malodorous solids, liquids, or gases
which either singly or by interaction with other wastes are sufficient
to create a public nuisance or a hazard to life or are sufficient
to prevent entry into the sewers for their maintenance or repair.
(6)
Oils and grease. Any commercial, institutional, or
industrial wastes containing fats, waxes, grease, or oils which become
visible solids when the wastes are cooled to 10º centigrade (50º
Fahrenheit); any petroleum oil, nonbiodegradable cutting oil, or products
of mineral oil origin, in excess of 100 mg/l or in amounts that will
cause interference or pass-through.
(7)
Any wastewater which will cause interference or pass-through.
(8)
Any wastewater with objectionable color which is not
removed in the treatment process, such as, but not limited to, dye
wastes, and vegetable tanning solutions.
(9)
Any solid, liquid, vapor, or gas having a temperature
higher than 65º C. (150º F.); however, such materials shall
not cause the POTW treatment plant influent temperature to be greater
than 40º C. (104º F.). The Town Board reserves the right,
in certain instances, to prohibit or limit the discharge of wastes
whose maximum temperatures are lower than 65º C.
(10)
Unusual flow rate or concentration of wastes,
constituting slugs, except by industrial wastewater permit.
(11)
Any wastewater containing any radioactive wastes
except as approved by the Town Board, and in compliance with applicable
state and federal regulations.
(12)
Any wastewater which causes a hazard to human
life or which creates a public nuisance, either by itself or in combination,
in any way, with other wastes.
(13)
Any wastewater with a closed-cup flashpoint
of less than 140º Fahrenheit or 60º Centigrade using the
test methods specified in 40 CFR Part 261.21.
(14)
Any pollutants which result in the presence
of toxic gases, vapors or fumes within the POTW in a quantity that
may cause acute worker health and safety problems.
A.
No person shall discharge, directly or indirectly,
into the POTW, wastewater containing any of the following substances
in concentrations exceeding those specified below on either a daily
or an instantaneous basis, except by permit or as provided for in
this section. Concentration limits are applicable to wastewater effluents
at the point just prior to discharge into the POTW (end-of-pipe concentrations).

B.
To assure that none of the above noted limitations
are violated, the Town Board shall issue permits to significant industrial
users limiting the discharge of the substances noted above. Each permit
shall restrict the discharge from each significant industrial user
to a portion of the total allowable influent loading. In determining
what portion of the total of each substance that each significant
industrial user shall be allowed to discharge, the Town Board shall
consider:
(1)
The quantities of each substance that are uncontrollable
because they occur naturally in wastewater;
(2)
The quantities of each substance that are anthropogenic
but are nonetheless uncontrollable;
(3)
Historical discharge trends;
(4)
Past pollution control efforts of each significant
industrial user as compared to other significant industrial dischargers
of the same substance;
(5)
Potential for growth in the POTW service area;
(6)
Potential for more restrictive regulatory requirements
to be placed on the POTW discharge or sludge disposal or sludge reuse
method; and
(7)
Treatability of the substance. The Town Board shall
apply a minimum safety factor of 15% to be protective of the POTW.
A.
Limitations on wastewater strength or mass discharge
contained in this chapter may be supplemented with more stringent
limitations when, in the opinion of the Town Board:
(1)
The limitations in this chapter are not sufficient
to protect the POTW;
(2)
The limitations in this chapter are not sufficient
to enable the POTW treatment plant to comply with applicable water
quality standards or the effluent limitations specified in the POTW's
SPDES permit;
(3)
The POTW sludge will be rendered unacceptable for
disposal or reuse as the Town desires, as a result of discharge of
wastewaters at the above prescribed concentration limitations;
(4)
Municipal employees or the public will be endangered;
or
(5)
Air pollution and/or groundwater pollution will be
caused.
B.
The limitations on wastewater strength or mass discharge
shall be recalculated not less frequently than once every five years.
The results of these calculations shall be reported to the Town Board.
This chapter shall then be amended appropriately. Any issued industrial
wastewater discharge permits, which have limitations, based directly
on any limitations, which were changed, shall be revised and amended,
as appropriate.
The Town Board shall have the authority to copy
any record related to wastewater discharges to the POTW.
A.
Except where expressly authorized to do so by an applicable
pretreatment standard, no user shall ever increase the use of process
water or, in any other way, attempt to dilute a discharge as a partial
or complete substitute for adequate treatment to achieve compliance
with a pretreatment standard.
B.
Dilution flow shall be considered to be inflow.
Grease, oil, and sand interceptors shall be
provided, when, in the opinion of the DR, they are necessary for the
proper handling of wastewater containing excessive amounts of grease,
flammable substances, sand, or other harmful substances; except that
such interceptors shall not be required for private living quarters
or living units. All interceptors shall be of type and capacity approved
by the Town Board and shall be so located to be easily accessible
for cleaning and inspection. Such interceptors shall be inspected,
cleaned, and repaired regularly, as needed, by the owner, at his expense.
Solid waste grinders at or serving commercial
establishments, institutions or industries shall not discharge into
the Town POTW if there is a combined sewer overflow (CSO) on the sewer
lines conveying the waste to the POTW treatment plant.
The Town Board may reject a user's wastewater when it is has been determined that the wastewater contains substances or possesses characteristics which have a deleterious effect on the POTW and its processes, or on the receiving water, or which constitute a public nuisance or hazard. See § 169-78.
