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.
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.
Without limiting the generality of the foregoing, a user may not contribute
the following substances to the POTW:
A. 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 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.
B. 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, wastepaper, wood, plastics, gas, tar asphalt residues,
residues from refining or processing fuel or lubricating oil, mud,
or glass grinding or polishing wastes.
C. 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.
D. 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.
E. 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.
F. Oils and grease. Any commercial, institutional, or industrial wastes
containing floatable fats, waxes, grease, or oils, or which become
floatable when the wastes cool to the temperature prevailing, in the
wastewater at the POTW treatment plant, during the winter season;
also any commercial, institutional, or industrial wastes containing
more than 100 mg/l of emulsified oil or grease; also any substances
which will cause the sewage to become substantially more viscous at
any seasonal sewage temperature in the POTW.
G. Any substance which will cause interference or pass through.
H. 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.
I. 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 wastes at temperatures lower than 65° C.
J. Unusual flow rate or concentration of wastes, constituting slugs,
except by industrial wastewater permit.
K. Any wastewater containing any radioactive wastes except as approved
by the Superintendent and in compliance with applicable state and
federal regulations.
L. 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, including but not limited to antibiotics; hospital and/or
medical waste or discharges; discharges containing pathogenic organisms;
nonbiodegradable wastes from industrial processes, except as otherwise
allowed under this chapter; laboratory wastes; chemical compounds
which, upon acidification, alkalization, oxidation or reduction in
the discharge or after admixture with wastewater and its components
in the POTW, produce toxic, flammable, or explosive compounds; and
pesticides, including algaecides, fungicides, herbicides, insecticides
and rodenticides.
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 Section 903. Concentration limits are applicable to wastewater effluents
at point just prior to discharge into the POTW (end of pipe concentrations).

NOTE:

(1)
|
Except for chromium (hex), all concentrations listed for metallic
substances shall be "total" or 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.
|
(2)
|
Daily concentrations shall be as determined on a composite sample
taken from the user's daily discharge over a typical operational and/or
production day.
|
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. "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; 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 Superintendent
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.
