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 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.[1]
[1]
Editor's Note: See 33 U.S.C. § 1317(a).
(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 fats, waxes, grease or oils 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.
(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 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
this section. Concentration limits are applicable to wastewater effluents
at a point just prior to discharge into the POTW (end of pipe concentrations).

The permittee shall inspect each tributary dental facility at
least once every five years to verify compliance with the wastewater
treatment operation, maintenance, and notification elements of 6 NYCRR
Part 374.4. Inspection and/or outreach to other industrial/commercial
sectors which may contribute mercury is also recommended. All new
or increased tributary discharges, including hauled wastes, which
are from sources that are industrial in nature must be evaluated for
mercury content, and if levels exceed 500 ng/l then authorization
must be obtained from the Department prior to acceptance. A file shall
be maintained containing the notices submitted by dental offices and
all other pertinent information. This file shall be available for
review by DEC representatives, and copies shall be provided upon request.
Note that a permit modification may be necessary to include more stringent
requirements for POTWs which do not maintain low mercury effluent
levels.
|
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 procedures.
A.
At no time shall the influent to the POTW contain
quantities in excess of those specified below:

B.
Permits.
(1)
To assure 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 safety factor of
15% 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 Part 2 may be supplemented with more stringent limitations
when, in the opinion of the Superintendent:
(1)
The limitations in this Part 2 are not sufficient
to protect the POTW;
(2)
The limitations in this Part 2 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 Part 2 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 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 or her expense.
