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
water to the district sewage system.
No person shall discharge or cause to be discharged
any of the following described waters or wastes to the district sewage
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 liquid, 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 district sewage system and
plant or to the operation of the district sewage system and 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 be over 10% of the
lower explosive limit (LEL) of the meter.
B. Contain any noxious, malodorous gas or substance which
is present in quantities that create a public nuisance or a hazard
to life.
C. Cause corrosive damage or hazard to structures, equipment
or personnel of the district sewage system and plant but in no case
discharges with the following properties: having a pH lower than 5.0
or greater than 10.0 for more than 10% of the time in a twenty-four-hour
period; having a pH lower than 3.5 or greater than 12.0 for any period
exceeding 15 minutes. These requirements may be modified for facilities
designed to accommodate greater ranges.
D. Cause obstruction to the flow in sewers or other interferences
with the operation of the district sewage system and 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 district sewage system and
plant.
E. Contain garbage, refuse or household waste materials,
whether or not the same is ground or shredded.
[Added 7-8-1996 by L.L. No. 4-1996]
No person shall discharge or cause to be discharged
the following described substances, materials, waters or wastes to
the district sewage system without the prior approval of the Town
Board of the Town of Liberty:
A. Materials which constitute a rate of discharge or
substantial deviation from normal rates of discharge (slug discharge),
sufficient to cause interference of the operation and performance
of the district sewage system and plant.
B. Materials which contain heat in amounts which will
accelerate the biodegradation of wastes, causing the formation of
excessive amounts of hydrogen sulfide in the district sewage system
or inhibiting biological activity in the plant, but in no case shall
the discharge of heat cause the temperature in the district sewage
system to exceed 65.5° C. (150° F.) or the temperature of
the indolent to the treatment facilities to exceed 40° C. (104°
F.) unless the facilities can accommodate such heat.
C. Materials which 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° C. to 65°
C.).
D. Materials which contain floatable oils, fat or grease.
E. Waters or wastes containing strong acids, iron pickling
wastes or concentrated plating solutions, whether neutralized or not.
F. Materials which contain any odor or color-producing
substances exceeding concentration limits which may be established
for purposes of meeting the SPDES permit.
G. Materials which contain radioactive wastes or isotopes
of such half-life or concentration as may exceed limits established
by the Administrator in compliance with applicable Town, state and
federal regulations.
H. Any waters or wastes having a pH in excess of twelve
point zero (12.0).
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 chlorine and sodium sulfate).
(2) Excessive coloration (such as but not limited to dye
wastes and vegetable tanning solutions).
(3) A BOD in excess of 240 milligrams per liter.
(4) A chlorine demand in excess of 25 milligrams per liter.
(5) A chemical oxygen demand in excess of 600 milligrams
per liter.
(6) Suspended solids in excess of 300 milligrams per liter.
J. Waters or wastes containing substances which are not
amenable to treatment or reduction by the sewage treatment process
employed by the plant or are amenable to treatment only to such degree
that the plant effluent cannot meet the requirements of agencies having
jurisdiction over discharge to the receiving waters.
K. Effluent concentrations in excess of the following
limits for toxic substances.

1 Effluent limitations
promulgated by the Federal Water Pollution Control Act (the Act) shall
apply in any instance where they are more stringent than those in
this chapter. Under Section 307(b) of the Act, federal pretreatment
standards are designed to achieve two purposes: to protect the operation
of publicly owned treatment works and to prevent the discharge of
pollutants which pass through such works inadequately treated. Users
in industrial categories subject to effluent guidelines issued under
Section (b) of the Act, which are discharging incompatible pollutants
to publicly owned treatment works, are required to adopt the best
practical control technology currently available, as defined by the
administrative head pursuant to Section 304(b) of the Act.

Grease, oil and sand interceptors shall be provided
when, in the opinion of the Town Board of the Town of Liberty 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 or her expense.
[Amended 9-19-2016 by L.L. No. 3-2016]
When required by the Town Board of the Town of Liberty in its
sole discretion, the owner of any property connected to and discharging
into a district sewage system either (i) industrial waste, or (ii)
in excess of 3,000 gallons of average daily flow of sewage in any
given month, shall install at such property owner's sole cost
and expense (inclusive of Town engineering and professional expenses)
a manhole and flowmeter acceptable to the Town Board, the Administrator
and the Town's Engineer, in order to facilitate observation,
sampling and measurement of waste as well as inspection by the Town.
The manhole shall be located and the meter installed so as to be safe
and accessible by Town personnel and constructed in accordance with
plans approved by the Administrator. All maintenance, repairs and
replacements thereof, and annual calibration of meters, shall be at
the property owner's sole expense (inclusive of Town engineering
and professional expenses) and performed by contractors approved in
advance by the Town Board.
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 control manhole
has been required, the control manhole shall be considered to be the
point at which the building sewer is connected to the septic tank
in the district septic system for the Briscoe Road Sewer District,
Loomis Sewer District and Loomis Extension Sewer District or the nearest
downstream manhole in the district sewage system to the point at which
the building sewer is connected for the Infirmary Road Sewer District,
Swan Lake Sewer District No. 1 and Swan Lake Sewer District No. 2.
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 is determined from periodic grab samples.
