All users within the Gananda Sewer District 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 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.
(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 or 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 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 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 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 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.
A.
No person shall discharge, directly or indirectly, into the sewer
system of the Gananda Sewer district 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 herein. 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 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.
|
B.
Other substances which may be limited are:
(1)
Antibiotics.
(2)
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.
(3)
Pesticides, including algicides, fungicides, herbicides, insecticides
and rodenticides.
(4)
Polyaromatic hydrocarbons.
(5)
Viable pathogenic organisms from industrial processes or hospital

B.
Considerations.
(1)
To ensure that none of the above noted limitations are violated,
the Superintendent 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. In determining
what portion of the total of each substance that each significant
industrial user shall be allowed to discharge, the superintendent
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 Superintendent shall apply a 15% safety factor protective of
the POTW.
C.
All samples of influent loads to the POTW must be tested by a laboratory
certified by the New York State Department of Health.
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:
[Amended 3-28-1996 by L.L. No. 2-1996]
(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 State Pollutant
Discharge Elimination System (SPDES) permit;
(3)
The POTW sludge will be rendered unacceptable for disposal or reuse
as the Town of Walworth 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 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.
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 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 a 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.
