No person may discharge any stormwater, surface water, groundwater,
roof runoff, subsurface drainage, uncontaminated cooling water or
unpolluted industrial process water to any sanitary sewer.
Stormwater and all other unpolluted drainage must be discharged
to such sewers as are specifically designated as storm sewers or to
a natural outlet. With approval of the Superintendent and DEC, industrial
cooling water or unpolluted industrial process waters may be discharged
to a storm sewer or natural outlet.
No person may discharge or deposit into the wastewater treatment
system any wastewater which contains the following:
A.
Explosive mixtures. Liquids, solids or gases which may, either alone
or by interaction with other substances, cause fire or explosion or
be injurious in any way to the wastewater treatment system or to the
operation of the system. At no time may two successive readings on
an explosion hazard meter, at the point of discharge into the public
sewer system, be more than 5%, nor may any single reading be over
10% of the lower explosive limit (LEL) of the meter.
B.
Toxic substances. Toxic substances in amounts exceeding standards
promulgated by the Administrator of EPA pursuant to Section 307(a)
of the Act and chemical elements or compounds, phenols or other taste-
or odor-producing substances or any other substances which, singly
or by interaction with other wastes, are not susceptible to treatment
or which may interfere with the biological processes or efficiency
of the wastewater treatment system or that will pass through the system
without being treated to the required degree.
C.
Corrosive wastes. Any waste which will cause corrosion or deterioration
of the wastewater treatment system. All wastes discharged to the public
sewer system must have a pH value in the range of six to nine standard
units.
D.
Solid or viscous wastes. Solid or viscous substances in quantities
or of such size capable of causing obstruction to the flow in sewers
or other interference with the proper operation of the wastewater
treatment system. This prohibition includes any wastewater which,
by interaction with other waters or wastes in the public wastewater
treatment system, forms suspended solids which obstruct the flow in
the sewer or create a condition that interferes with the proper operation
of the wastewater treatment system.
E.
Oil and grease. Any wastewater containing fats, wax, grease or oils,
whether emulsified or not, in excess of 100 milligrams per liter or
containing substances which may solidify or become viscous at temperatures
between 32° and 150° F. [0° and 65° C.].
F.
Excessive temperature. Any wastewater having a temperature higher
than 150° F. [65° C.] or in such quantities that the temperature
at the treatment works influent exceeds 104° F. [40° C.].
G.
Improperly shredded garbage. Garbage that has not been ground or
commuted to such a degree that all particles will be carried freely
in suspension under flow conditions normally prevailing in the public
sewers, with no particle greater than 1/2 inch in any dimension.
H.
Noxious materials. Noxious or malodorous solids, liquids or gases
which, either singly or by interaction with other wastes, are capable
of creating a public nuisance or hazard or may be sufficient to prevent
entry into a sewer for its maintenance and repair.
I.
Radioactive wastes. Radioactive wastes or isotopes of such half-life
or concentration that they do not comply with regulations or orders
issued by the appropriate authority having control over their use
and/or which may cause damage to the wastewater treatment system or
danger to personnel operating the system.
J.
Excessive discharge rate. Quantities of wastewater flow or concentrations,
or both, which constitute a slug as defined herein.
K.
Discolored material. Wastes with color, such as but not limited to
dye water or vegetable tanning solution, that are not removable by
the treatment process.
L.
Any substance which may cause the wastewater treatment system effluent
or any other product of the wastewater treatment system, such as residues,
sludge or scums, to be unsuitable for a reclamation process where
the wastewater treatment system is pursuing a reuse and reclamation
program. No substance discharged into the wastewater treatment system
may cause the system to be in noncompliance with sludge use or disposal
criteria, guidelines or regulations affecting sludge use or development
pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic
Substance Control Act or state criteria applicable to the sludge management
method being used.
A.
General limitations on incompatible pollutants. No person may discharge
or convey or permit or allow to be discharged or conveyed to a public
sanitary sewer any wastewater containing incompatible pollutants of
such character or quantity that will:
(1)
Violate pretreatment standards.
(2)
Cause the wastewater treatment works to violate its SPDES permit
requirements.
(3)
Violate the provisions of this chapter or other applicable laws,
rules or regulations.
(4)
Not be susceptible to treatment or interfere with the process or
efficiency of the treatment system.
B.
Specific limitations on certain compatible pollutants. The following
are the maximum concentrations of pollutants allowable in wastewater
discharges to the wastewater treatment system as established by the
DEC. This chapter includes by reference any future revisions or additions
to this list as promulgated by the DEC or the EPA. Dilution of any
wastewater discharge for the purpose of satisfying these requirements
is a violation of this chapter.

C.
Limitations on compatible pollutants. In cases where the effluent characteristics of an industrial or commercial discharge exceed the permissible limits for the compatible pollutants listed below, the acceptability of such waste will be left to the engineering judgment of the village or any other federal, state or local agencies having jurisdiction. The primary judgment criteria for the determination of acceptability by the village and responsible authorities will be whether the admission of such waste will overload the wastewater treatment system. If it is determined that it will not overload the system, permission to discharge said compatible pollutants may be granted. However, the village will require (in accordance with Article IX and any resolutions adopted thereunder) the payment of an additional industrial operation and maintenance surcharge for the additional cost and a user charge for the additional capital construction costs to cover the cost of treating the excessive strength wastewater. This charge is in addition to any sewer charges for the nonexcessive waste discharge. "Excessive strength wastewater" is defined as:
(1)
Concentrations of inert suspended solids which exceed 250 milligrams
per liter, such as but not limited to Fuller's earth, lime slurries
and lime residues or dissolved solids, such as but not limited to
sodium chloride in concentrations greater than 10,000 milligrams per
liter and sodium sulfate in concentrations greater than 500 milligrams
per liter.
(2)
Concentrations of BOD which exceed 200 milligrams per liter.
(3)
Chlorine demand requirements exceeding nine milligrams per liter.
(4)
Concentrations of free ammonia which exceed 25 milligrams per liter.
