No person shall discharge into any public sewer
of the Village of Port Chester any waste, substance or waters other
than such kinds or types of waters or water-carried wastes for the
conveyance of which the particular public sewer is intended, designed
or provided.
No person shall discharge or cause to be discharged
any stormwater, surface drainage, cooling water, air conditioning
and refrigerating wastewaters, or unpolluted industrial process waters
to any sanitary sewer.
Stormwater and all other unpolluted drainage
or uncontaminated process water in excessive quantities shall be discharged
to storm sewers or to a natural outlet. Such waters shall be discharged
only after approval of any local, county or state regulatory agency
having jurisdiction.
Except as hereinafter provided, no person shall
discharge or cause to be discharged any of the following described
waters or wastes to any public sewer:
A. Any liquid or vapor having a temperature higher than
150° F.
B. Any water or waste which may contain more than 100
milligrams per liter by weight of fat, oil, wax or grease, or containing
other substances which may solidify or become viscous at temperatures
between 32° F. and 150° F.
C. Any gasoline, benzene, naphtha, alcohol, tar, fuel
oil or other flammable or explosive liquid, solid, gas or vapor.
D. Any garbage except properly shredded garbage. The
installation and operation of any garbage grinder equipped with a
motor of 3/4 horsepower or greater shall be subject to the review
and approval of the Superintendent.
E. Any ashes, cinders, stones, sand, mud, straw, shavings
or sawdust, metal, sticks, coarse rubbish, glass, rags, tar, feathers,
plastics, waste rubber, animal guts or tissues, entrails, blood, hair,
hides, wood, paunch manure or any other substance likely to damage,
destroy or cause an obstruction to the flow in any sewer or which
may interfere with the proper operation of the sewage works.
F. Any waters or wastes containing a toxic, poisonous
or radioactive substance in sufficient quantity to injure or interfere
with any sewage treatment process or to constitute a hazard to humans,
animals or marine life, or create any hazard in the receiving wastes.
Radioactive wastes or materials may be discharged into a public sewer
if Conditions I and II below are met and if either Condition III or
IV is also met, provided that such discharges are in compliance with
applicable state or federal regulations:
(1) Condition I. Such wastes must be readily soluble or
dispensable in water.
(2) Condition II. The gross quantity of all radioactive
materials so discharged must not exceed one curie per year.
(3) Condition III. The daily quantity of any radioactive
material, if diluted by the average daily volume of sewage discharged
into the system from the installation must not exceed the maximum
concentrations allowed by regulations of the United States Atomic
Energy Commission.
(4) Condition IV. Daily quantities of radioactive materials
up to the maximum permitted by the United States Atomic Energy Commission
may be so discharged provided that the total monthly quantities, if
diluted by the average monthly volume of sewage discharged from the
installation, do not exceed the concentrations permissible under Condition
III above.
G. Any waters, sewage or wastes having a pH lower than
5.0 or higher than 9.5, or having any other corrosive or detrimental
property capable of causing damage or hazard to the sewage works or
personnel.
H. Any noxious, malodorous or taste-producing gas, vapor
or substance, such as phenols, capable of creating a public or private
nuisance or which may prove toxic to sewage treatment processes or
which may exceed acceptable limits for discharge to receiving waters.
(1) Any waters containing strong acid iron-pickling wastes
or concentrated plating solutions whether neutralized or not.
(2) Any water containing iron, copper chromium, zinc and
similar objectionable toxic substances.
(3) Toxic substances and pathogenic bacteria. The following
is a partial list of toxic substances and pathogenic bacteria, the
discharge of which into the village sewer system or public sewers
tributary thereto is hereby prohibited unless their concentration
is reduced by treatment at the source to a point that will meet the
general purposes of these rules, regulations and ordinances or come
within the applicable standards set forth herein, and will not adversely
affect any of the biochemical, chemical or other sewage treatment
processes:
[Added 9-25-1972]
(c)
Bromine, iodine, chlorine.
(j)
Silver and silver compounds.
(k)
Sulfonamides, toxic dyes (organic or mineral).
(m)
All strong oxidizing agents such as chromates,
dichromates, permanganates, peroxides, etc.
(n)
Strong reducing agents such as nitrites, sulfides,
sulfites thiosulfates, etc.
(o)
Wastes from industrial processes or hospital
procedures containing viable pathogenic organisms.
(4) Permissible concentration of toxic substances. The
concentration in sewage of any of the following toxic substances shall
not exceed these concentrations judged by the Superintendent to be
toxic to biological sewage treatment processes or to the biota of
the receiving waters and shall not exceed the limits specified below
when they are discharged to the sewer. These limits may be revised
by the Superintendent whenever in his opinion operating experience
so indicates:

I. Materials which exert or cause:
(1) Unusual concentrations of inert suspended solids (such
as, but not limited to, fuller's earth, lime slurries, and lime residues)
or of dissolved solids (such as, but not limited to, sodium chloride
and sodium sulfate).
(2) Excessive discoloration (such as, but not limited
to, dye wastes and vegetable tanning solutions).
(3) Unusual BOD, suspended solids, chemical oxygen demand,
or chlorine requirements in such quantities as to constitute a significant
load on the sewage treatment works.
(4) Unusual volume of flow or concentration of wastes
constituting "slugs" as defined herein.
J. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment process
employed, or are amenable to treatment only to such degree that the
sewage treatment plant effluent cannot meet the requirements of other
agencies having jurisdiction over discharge to the receiving waters.
In determining whether any waste discharged
or proposed to be discharged into any public sewer is to be excluded,
consideration will be given to the quantity, time or times, rate and
manner of discharge, dilution and character of the waste in question,
the size of the sewer into which the waste is to be discharged, the
probable quantity of sewage or other wastes likely in said sewer,
and other pertinent facts. Minute quantities of a waste which would
be objectionable in larger quantity may be accepted if sufficiently
diluted when and as discharged or if the quantity discharged is small
as compared with the flow in the receiving sewer; but any permission
to discharge minute quantities of all otherwise excluded waste shall
be revocable at any time by the village.
No waste waters or substances which are excluded
from sanitary sewers shall be discharged into any storm sewer.
All measurements, tests and analyses of the
characteristics of waters and wastes to which reference is made in
this section shall be determined in accordance with "Standard Methods
For the Examination of Water and Sewage." In the event that no special
manhole has been required, the control manhole shall be considered
to be the nearest downstream manhole in the public sewer to the point
at which the building sewer is connected.
No statement contained on this section shall
be construed as preventing any special agreement or arrangement between
the village and any industrial concern whereby an industrial waste
of unusual strength of character may be accepted by the village for
treatment, subject to payment therefore by the industrial concern.
