All users of the Village POTW shall 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 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 may 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 5%, nor any single reading be more than 10% 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,
fuel oil, toluene; xylene, ethers, alcohols, carbides, hydrides, sulfides
and any other substance which the Village, the state or the EPA has determined
to be a fire hazard or a hazard to the POTW.
(2)
Solid or viscous substances in such quantities or of
such size as to be capable of causing obstruction to the flow in a sewer or
interference with the proper operation of the wastewater treatment facilities.
Unless explicitly allowable by a written permit, such substances include but
are not limited to grease, shredded garbage, 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, wastepaper, wood, plastics, gas,
tar asphalt residues, residues from refining or processing fuel or lubricating
oil, mud, glass or stone grinding or polishing wastes, paper dishes, cups
or milk containers, either whole or ground.
(3)
Any wastewater having a pH less than 5.5 or greater than
8.5, 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 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 human or animal life or are sufficient to
prevent entry into the sewers for their maintenance or repair.
(6)
Oils and grease.
(a)
Any commercial, institutional or industrial wastes containing
fats, waxes, grease or oils which become visible solids when the wastes are
cooled to 10° C. (50° F.); or
(b)
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 65° C. (150° F.). However, such materials shall not cause
the POTW treatment plant influent temperature to be greater than 40° C.
(104° F.). The Superintendent reserves the right, in certain instances,
to prohibit or limit the discharge of wastes at maximum temperatures which
are lower than 65° C.
(10)
Unusual flow rate or concentration of wastes, constituting
slugs, except as permitted by industrial wastewater permit.
(11)
Any wastewater containing any radioactive wastes, except
as approved by the Superintendent 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
140° F. or 60° C. using the test methods specified in 40 CFR 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, 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.
Except for hexavalent chromium, all concentrations listed
for metallic substances shall be as "total metal," which shall be defined
as the value measured in a sample acidified to a pH value of two or less,
without prior filtration.
C.
Other substances which may be limited are:
(1)
Antibiotics.
(2)
Chemical compounds which, upon acidification, alkalinization,
oxidation or reduction in the discharge or after admixture with wastewater
and its components in the POTW, produce toxic, flammable or explosive compounds.
(3)
Pesticides, including algicides, fungicides, herbicides,
insecticides and rodenticides.
(4)
Polyaromatic hydrocarbons.
(5)
Viable pathogenic organisms from industrial processes
or hospital procedures.
A.
Limitations on wastewater strength contained in this
chapter may be supplemented with more stringent limitations when, in the opinion
of the Superintendent:
(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 Village desires, as a result of discharge of wastewaters at
the above-prescribed concentration limitations;
(4)
Municipal employees or the public may be endangered;
or
(5)
Air pollution and/or groundwater pollution may be caused.
B.
The limitations on wastewater strength shall be recalculated
not less frequently than once every five years. The results of these calculations
shall be reported to the Village. 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.
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 Superintendent, they are necessary for the proper handling of wastewater
containing excessive amounts of grease, flammable substances, sand or other
harmful substances. However, said interceptors shall not be required for private
living quarters or dwelling units. All interceptors shall be of type and capacity
approved by the Superintendent and shall be so located as to be easily accessible
for cleaning and inspection. Said interceptors shall be inspected, cleaned
and repaired regularly, as needed, by the owner, at his own expense.
