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.
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 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 one-half (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 glass-polishing wastes.
(3)
Any wastewater having a pH less than five point five
(5.5) or greater than nine point five (9.5), 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 § 148-3 of this Part 1.
(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 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 milligrams per liter 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.
(7)
Any substance which will cause interference or pass-through.
(8)
Any wastewater with objectionable color which is not
removed in 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 Town Engineer reserves the right, in certain instances,
to prohibit wastes at temperatures 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 Town Engineer 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.
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 § 148-50. Concentration limits are applicable to wastewater effluents at a point just prior to discharge into the POTW (end of pipe concentrations).

NOTES:
1 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 point zero
(2.0) or less, without prior filtration.
|

2 As determined on a composite sample taken
from the user's daily discharge over a typical operational and/or production
day.
3 As determined on a grab sample taken from
the user's discharge at any time during the daily operational and/or
production period.
|
4 Other substances which may be limited are
antibiotic 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; pesticides,
including algicides, fungicides, herbicides, insecticides or rodenticides;
polyaromatic hydrocarbons; or viable pathogenic organisms from industrial
processes or hospital procedures.

B.
To assure that none of the above-noted limitations are
violated, the Town Engineer shall issue permits to significant industrial
users limiting the discharge of the substances noted above. Each permit shall
restrict the discharge from each significant industrial user to a portion
of the total allowable influent loading.
(1)
In determining what portion of the total of each substance
that each significant industrial user shall be allowed to discharge, the Town
Engineer 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.
(g)
Treatability of the substance.
(2)
The Town Engineer shall apply a fifteen-percent safety
factor protective of the POTW.
A.
Limitations on wastewater strength or mass discharge
contained in this Part 1 may be supplemented with more stringent limitations
when, in the opinion of the Town Engineer:
(1)
The limitations in this Part 1 are not sufficient to
protect the POTW.
(2)
The limitations in this Part 1 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.
(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 Part
1 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 Town Engineer, 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 acceptable to the Town Engineer and shall be so located as 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.
