No person shall discharge or cause to be discharged any of the
following described waters or wastes to the Town sewer system:
A. Gasoline, benzene, naptha, fuel oil, or other flammable or explosive
liquid, solid, or gas.
B. Waters or wastes, containing toxic or poisonous solids, liquids,
or gases, in sufficient quantity, either singly or by interaction
with other wastes, which injures or interferes with any sewage process,
constitute a hazard to humans or animals, create a public nuisance,
or create any hazard in the receiving waters of the sewage treatment
plant, including, but not limited to, cyanides. Without limiting the
generality of the foregoing, no person shall discharge, or cause to
be discharged, waters or wastes to any public sewer which contain
substances having concentration limits in excess of those set forth
in Table 7-1 annexed hereto.
C. Waters or wastes having a pH lower than 5.5, or having any other
corrosive property capable of causing damage or hazard to structures,
equipment, and personnel of sewage works.
D. Solid or viscous substances in quantity, or of such size, capable
of causing obstruction to the flow in sewers, or other interference
with the proper operation of the sewage works, such as, but not limited
to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags,
feathers, tar, plastics, wood, whole blood, paunch manure, hair fleshings,
entrails, paper dishes, cups, and milk containers, either whole or
ground by garbage grinders.
No person shall discharge or cause to be discharged the following
described substances, material, waters, or wastes to the Town's
sewer system without the prior approval of the Town Board:
A. Liquid or vapor having a temperature higher than 150° F. (65°
C.); or in such quantities that the temperature at influent to the
treatment works exceeds 40° C. or 104° F.;
B. Water or wastes 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°
F. and 150° F. (0° C. and 65° C.);
C. Garbage that has not been properly shredded;
D. Waters or wastes containing strong acids, iron pickling wastes, or
concentrated plating solutions, whether neutralized or not;
E. Waters or wastes containing iron, chromium, copper, zinc, and similar
objectionable or toxic substances, or wastes exerting an excessive
chlorine requirement, to such degree that any such material received
in the composite sewage at the sewage treatment works exceeds the
limits established by the Town Board for such materials;
F. Waters or wastes containing phenols or other taste- or odor-producing
substances, in such concentration exceeding limits which may be established
by the Town Board after treatment of the composite sewage to meet
the requirements of the state, federal, or public agencies having
jurisdiction for the discharge to the receiving waters;
G. Any radioactive wastes or isotopes;
H. Any waters or wastes having a pH in excess of 9.5;
I. Materials which exert or cause:
(1) Unusual concentration of inert suspended solids (such as, but not
limited to, Fuller's earth lime residues) or dissolved solids
(such as, but not limited to, sodium chloride and sodium sulfate);
(2) Excessive coloration (such as, but not limited to, dye wastes and
vegetable tanning solutions);
(3) Excessive discharges:
(a)
A BOD in excess of 240 milligrams per liter;
(b)
A chlorine demand in excess of 25 milligrams per liter;
(c)
A chemical oxygen demand in excess of 600 milligrams per liter;
(d)
Suspended solids in excess of 300 milligrams per liter;
(e)
Having an average daily flow greater than 2% of the average
daily sewage flow of any sewer district.
(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 by
any Town water pollution control facilities or are amenable to treatment
only to such degree that the sewage treatment plant's effluent
cannot meet the requirements of agencies having jurisdiction over
discharge to the receiving waters.
K. Waters or wastes generated by a significant industrial user, as defined
in this chapter.
Where preliminary treatment or flow-equalizing facilities are
provided for any waters or wastes, they shall be maintained continuously
in satisfactory and effective operation by the owner at his expense.
When required by the Town Board, the owner of any property serviced
by a building sewer carrying industrial wastes shall install a suitable
control manhole, together with such necessary meters and other appurtenances
in the building sewer to facilitate observation, sampling and measurement
of the wastes. Such a manhole, when required, shall be accessibly
and safely located, and shall be constructed in accordance with plans
approved by the Administrator. The manhole shall be installed by the
owner at his expense, and shall be maintained by him so as to be safe
and accessible at all times.
All measurements, tests and analyses of the characteristics
of waters and wastes to which reference is made in this chapter shall
be determined in accordance with the latest edition of Standard Methods
for the Examination of Water and Wastewater published by the American
Public Health Association, and shall be determined at the control
manhole provided, or upon suitable samples taken at said control manhole.
In the event that no special manhole has been required, the control
manhole shall be considered to be the nearest downstream manhole in
the Town sewer system to the point at which the building sewer is
connected. Sampling shall be carried out by customarily accepted methods
to reflect the effect of constituents upon the sewage works, and to
determine the existence of hazards to life, limb, and property. The
particular analyses involved will determine whether a twenty-four-hour
composite of all outfalls of a premises is appropriate, or whether
a grab sample or samples should be taken. Normally, but not always,
BOD and suspended solids analyses are obtained from 24 composites
of all outfalls, whereas pHs are determined from periodic grab samples.
