All users of the Village POTW will comply with all standards
and requirements of current federal, state, and local regulations.
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 POTW.
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.
(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 or current regulatory standards.
(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 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 whose maximum
temperatures are lower than 65° 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 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
or current standards.
(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.
C.
The Superintendent shall determine the total allowable influent load
of each substance from significant industrial users. In determining
the total load of each substance that significant industrial users
shall be allowed to discharge, the superintendent 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 Superintendent shall apply a minimum
safety factor of 15% to be protective of the POTW.
D.
To assure that the total loads so calculated for each substance are
not violated, the Superintendent shall issue permits to significant
industrial users limiting discharge loads.
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 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 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 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 Superintendent 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. 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 Village.
The Village Board may reject a user's wastewater, on recommendation of the Superintendent, 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 § 145-94 herein.
