No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated cooling water or unpolluted industrial process
waters to any sanitary sewer.
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 406-471. All users in the Fourth Ward Sewer Improvement Area
in the Town of Poughkeepsie are subject to the pretreatement standards,
implementation and enforcement as described and prescribed in the
intermunicipal agreement between the Town of Poughkeepsie and the
City of Poughkeepsie for such purpose.
A. General prohibitions. 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. 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 fleshing,
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 6.5 or greater
than 9.5, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment and/or POTW personnel.
(4) Any wastewater conditioning 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.
(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 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 150° F; however, such materials shall not cause the
POTW treatment plant influent temperature to be greater than 104°
F.
(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 managing 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. 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.
B. Concentration-based limitations. No person shall discharge,
directly or indirectly, into the POTW, wastewater containing any of
the follow substances in concentrations exceeding those specified
below on a daily basis, except by permit. Concentration limits are
applicable to wastewater effluent at the point just prior to discharge

C. Modification of limitations.
(1) Limitations on wastewater strength or mass discharge contained in Articles
X through
XIII may be supplemented with more stringent limitations when, in the opinion of the managing operator:
(a)
The limitations in Articles
X through
XIII are not sufficient to protect the POTW;
(b)
The limitations in Articles
X through
XIII 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;
(c)
The POTW sludge will be rendered unacceptable
for disposal or reuse as the Town desires, as a result of discharge
of wastewater at the above-prescribed concentration limitations;
(d)
Municipal employees or the public will be endangered;
or
(e)
Air pollution and/or groundwater pollution will
be caused.
(2) 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. Articles
X through
XIII 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.
D. Access to user's records. The managing operator shall
have the authority to copy any record related to wastewater discharges
to the POTW.
E. Dilution. 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.
F. Grease, oil and sand interceptors. Grease, oil and
sand interceptors shall be provided when, in the opinion of the managing
operator, 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 managing 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.
G. Rejection of wastewater. The Town Board or Board of
Appeals may reject a user's wastewater, on recommendation of the managing
operator, 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.
As a means of determining compliance with Articles
X through
XIII, with applicable SPDES permit conditions and with applicable state and federal law, each industrial user shall be required to notify the managing operator of any new or existing discharges to the POTW by submitting a completed industrial chemical survey (ICS) form and a completed industrial wastewater survey (IWS) form to the managing operator. The managing operator may require any user discharging wastewater into the POTW to file wastewater discharge reports and to supplement such reports as the managing operator deems necessary. All information shall be furnished by the user in complete cooperation with the managing operator.
No person shall cause the discharge of slugs
to the POTW. Each person discharging, into the POTW, greater than
100,000 gallons per day or greater than 5% of the average daily flow
in the POTW, whichever is lesser, shall install and maintain, on his
property and at his expense, a suitable storage and flow control facility
to ensure equalization of flow over a twenty-four-hour period unless
exempted by the Superintendent of Sewers. The facility shall have
a capacity for at least 50% of the daily discharge volume and shall
be equipped with alarms and a rate of discharge controller, the regulation
of which shall be directed by the managing operator. A wastewater
discharge permit may be issued solely for flow equalization.
Preliminary treatment and flow equalization facilities, or monitoring stations, if provided for any wastewater, shall be constructed and maintained continuously clean and safe and continuously operational by the owner at his expense. Where an industrial user has such treatment, equalization or monitoring facilities at the time Articles
X through
XIII are enacted, the managing operator and/or Town Engineer may approve or disapprove the adequacy of such facilities. Where the managing operator and/or Town Engineer disapproves of such facilities and construction of new or upgraded facilities for treatment, equalization or monitoring are required, plans and specifications for such facilities shall be prepared by a licensed professional engineer and submitted to the managing operator and/or Town Engineer. Construction of new or upgraded facilities shall not commence until written approval of the managing operator has been obtained.
No unauthorized person shall negligently break,
damage, destroy, uncover, deface, tamper with, prevent access or render
inaccurate, or cause or permit the negligent, breaking, damaging,
destroying, uncovering, defacing, tampering with, preventing access
or rendering inaccurate to:
A. Any structure, appurtenance or equipment which is
a part of the Town POTW.
B. Any measuring, sampling and/or testing device or mechanism installed pursuant to any requirement under Articles
X through
XIII except as approved by the managing operator.
In order that the industrial user's employees be informed of the Town requirements, a notice shall be permanently posted on appropriate bulletin boards within the user's facility advising employees of the Town requirements and whom to call in case of an accidental discharge in violation of Articles
X through
XIII.
When so requested in advance by an industrial
user, and when taking a sample of industrial wastewater, the Town
representative(s) shall gather sufficient volume of sample so that
the sample can be split into two nearly equal volumes, each of size
adequate for the anticipated analytical protocols, including any quality
control (QC) procedures. One of the volumes shall be given to the
industry whose wastewater was sampled, and the other shall be retained
by the Town for its own analysis.
