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 the Village sewer system.
No person shall discharge or cause to be discharged
any of the following described waters or wastes to the Village sewer
system which:
A. Create a fire or explosion hazard, including but not
limited to gasoline, benzene, naphtha, fuel oil or other flammable
or explosive liquid, solid, or gas, or any liquids, solids or gases
which by reason of their nature or quantity are sufficient, either
alone or by interaction with other substances, to cause fire or explosion
or be injurious in any other way to the Village sewer system and sewage
treatment plant or to the operation of the Village sewer system and
sewage treatment plant. At no time shall two successive readings on
an explosion hazard meter, at the point of discharge into the system
(or at any point in the system), be more than 5% nor any single reading
over 10% of the lower explosive limit (LEL) of the meter;
B. Contain noxious, malodorous gas or substance which
is present in quantities that create a public nuisance or a hazard
to life;
C. Corrosive properties.
(1) Cause corrosive damage or hazard to structures, equipment
or personnel of the Village sewer system and sewage treatment plant
but in no case discharges with the following properties:
(a)
Having the pH lower than 5.0 or greater than
10.0 for more than 10% of the time in a twenty-four-hour period.
(b)
Having a pH lower than three 3.5 or greater
than 12.0 for any period exceeding 15 minutes.
(2) These requirements may be modified for facilities
designed to accommodate greater ranges.
D. Cause obstruction to the flow in sewers or other interference
with the operation of the Village sewer system and sewage treatment
plant due to accumulation of solid or viscous materials; such substances
include, but are not limited to, grease, ashes, cinders, sand, mud,
straw, shavings, metal, glass, rags, feathers, tar, plastics, wood,
underground garbage, whole blood, paunch manure, hair and fleshings,
entrails and paper dishes, cups, milk containers, etc., in quantities
or of such size capable of impairing the hydraulic capacity of the
sewer or other interferences with the operation of the Village sewer
system and sewage treatment plant.
No person shall discharge or cause to be discharged
the following described substances, materials, waters or wastes to
the Village sewer system without the prior approval of the Village
Board:
A. Constitute a rate of discharge or substantial deviation
from normal rates of discharge (slug discharge) sufficient to cause
interference in the operation and performance of the Village sewer
system and sewage treatment plant.
B. Contain heat in amounts which will accelerate the
biodegradation of wastes, causing the formation of excessive amounts
of hydrogen sulfide in the Village sewer system or inhibit biological
activity in the wastewater treatment facilities, but in no case shall
the discharge of heat cause the temperature in the Village sewer system
to exceed 65.5° C. [150° F.)] or the temperature of the influent
to the treatment facilities to exceed 40° C. [104° F.)] unless
the facilities can accommodate such heat.
C. Contain nonbiodegradable 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.)].
D. Contain floatable oils, fat or grease.
E. Contain any garbage that has not been properly shredded.
F. Waters or wastes containing strong acids, iron pickling
wastes or concentrated plating solutions, whether neutralized or not.
G. Contain any odor- or color-producing substances exceeding
concentration limits which may be established for purposes of meeting
the SPDES permit.
H. Contain radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Administrator
in compliance with applicable Village, state and federal regulations.
I. Any waters or wastes having a pH in excess of 12.0.
J. 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 chlorine and sodium sulfate.
(2) Excessive coloration, such as but not limited to dye
wastes and vegetable tanning solutions.
(3) Other properties.
(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.
K. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment process
employed by the Village or are amenable to treatment only to such
degree that the sewage treatment plant effluent cannot meet the requirements
of agencies having jurisdiction over discharge to the receiving waters.
[Amended 1-6-1999 by L.L. No. 1-1999]
Grease, oil and sand interceptors shall be provided
and maintained by the property owner when, in the opinion of the Village
Board or the Administrator, such interceptors are necessary for the
proper handling of liquid wastes containing grease in excessive amounts,
or any flammable wastes, sand or other harmful ingredients. All interceptors
shall be of a type and capacity approved by the Administrator and
shall be located as to be readily and easily accessible for cleaning
and inspection.
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 Village 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 article 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 Village 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 premise
is appropriate or whether a grab sample or samples should be taken.
Normally, but not always, BOD and suspended solids analyses are obtained
from twenty-four-hour composites of all outfalls, whereas pH's are
determined from periodic grab samples.
