All users of the Town 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)
A toxic pollutant shall include, but not be limited to, any
pollutant identified pursuant to § 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 milligrams per liter 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 district operator 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 district operator, 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.
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 § 125-85. Concentration limits are applicable to wastewater effluents at the point just prior to discharge into the POTW ("end of pipe" concentrations).

B.
The district operator shall determine the total allowable influent
load of each substance from significant industrial users.
(1)
In determining the total load of each substance that significant
industrial users shall be allowed to discharge, the district operator
shall consider.
(a)
The quantities of each substance that are uncontrollable because
they occur naturally in wastewater;
(b)
The quantities of each substance that are anthropogenic but
are nonetheless uncontrollable;
(c)
Historical discharge trends;
(d)
Past pollution control efforts of each significant industrial
user as compared to other significant industrial dischargers of the
same substance;
(e)
Potential for growth in the POTW service area;
(f)
Potential for more restrictive regulatory requirements to be
placed on the POTW discharge or sludge disposal or sludge reuse method;
and
(g)
Treatability of the substance.
(2)
The district operator shall apply a minimum 15% safety factor to
be protective of the POTW.
C.
To assure that the total loads so calculated, for each substance,
are not violated, the district operator shall issue permits to significant
industrial users limiting discharge loads.
A.
Limitations on wastewater strength or mass discharge contained in
this article may be supplemented with more stringent limitations when,
in the opinion of the district operator:
(1)
The limitations in this article are not sufficient to protect the
POTW;
(2)
The limitations in this article 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 article
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 district operator 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 as 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. Grease interceptors shall be installed in
all commercial kitchen facilities serving at a minimum of one large
fueling per month. All interceptors shall be of type and capacity
approved by the district operator 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.
A.
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. Solid waste grinders for these purposes
shall be permitted only upon consent of a professional engineer.
B.
Solid waste grinders serving residential users shall be permitted
only with consent of a professional engineer.
The Town Board may reject a user's wastewater, on recommendation of the district operator, when it 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 § 125-119.
