All users of the Village 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 406-471.
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 Village, 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 6.0 or greater than 9.0, 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 10° C. (50° F.); 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 lower than
0° C. (32° F.) or higher than 65° C. (150° F.). Such
materials shall not cause the POTW treatment plant influent temperature
to be greater than 40° C. (104° F.). The Director of Public
Works reserves the right, in certain instances, to prohibit or limit
the discharge of wastes whose maximum temperatures are lower than
65° C.
(10)
Unusual flow rate or concentration of wastes, constituting slugs.
(11)
Any wastewater containing any radioactive wastes except as approved
by the Director of Public Works, 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 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.
(15)
Any water or wastes containing suspended solids of such character
and quantity that unusual attention or expense is required to handle
such materials at the wastewater treatment plant.
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. Concentration limits are applicable to wastewater
effluents at the point just prior to discharge into the POTW ("end
of pipe" concentrations).

A.
Except for chromium (hex), 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.
B.
As determined on a composite sample taken from the user's daily
discharge over a typical operational and/or production day.
C.

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 Director of Public Works:
(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 will be endangered, or
(5)
Air pollution and/or groundwater pollution will be caused.
B.
The limitations on wastewater strength shall be recalculated as the
Village deems necessary. The results of these calculations shall be
reported to the Village 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 Director of Public Works shall have the authority to copy
any record related to wastewater discharges to the POTW.
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.
Grease, oil, and sand interceptors shall be provided when, in
the opinion of the Director of Public Works, 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 Director of Public Works 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. Materials collected shall not be reintroduced into
the sewage system. The interceptors shall be readily accessible and
open to inspection by the Director of Public Works or authorized representative
upon request, at any time.
The Director of Public Works 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.
