No person(s) shall discharge or cause to be
discharged any unpolluted waters such as stormwater, groundwater,
roof runoff, subsurface drainage or cooling water to any sewer, except
stormwater runoff from limited areas, which stormwater may be polluted
at times, may be discharged to the sanitary sewer by permission of
the Superintendent.
[Amended 9-7-1982 by L.L. No. 6-1982]
Stormwater other than that exempted under §
212-23, and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm sewers or to a natural outlet approved by the Superintendent and other regulatory agencies. Unpolluted industrial cooling water or process waters may be discharged, on approval of the Superintendent, to a storm sewer, combined sewer or natural outlet. In addition, any such discharge requires a SPDES discharge permit and is subject to state and federal regulations.
The following described substances, materials,
waters or waste shall be limited in discharges to municipal systems
to concentration or quantities which will not harm either the sewers,
wastewater treatment process or equipment, will not have an adverse
effect on the receiving stream or will not otherwise endanger lives,
limb, public property or constitute a nuisance. The Superintendent
may set limitations lower than the limitations established in the
regulations below if, in his opinion, such more severe limitations
are necessary to meet the above objectives. In forming his opinion
as to the acceptability, the Superintendent will give consideration
to such factors as the quantity of subject waste in relation to flows
and velocities in the sewers, materials of construction of the sewers,
the wastewater treatment process employed, capacity of the wastewater
treatment plant, degree of treatability of the waste in the wastewater
treatment plant and other pertinent factors. The limitations or restrictions
on materials or characteristics of waste or wastewaters discharged
to the sanitary sewer which shall not be violated without approval
of the Superintendent are as follows:
A. Wastewater having a temperature higher than 150º
F. (65º C.). In addition, any discharge causing the influent
at the Ossining Sewerage Treatment Plant (OSTP) to be greater than
40º C. (104º F.).
[Amended 9-7-1982 by L.L. No. 6-1982]
B. Wastewater containing more than 25 milligrams per
liter of petroleum oil, nonbiodegradable cutting oils or product of
mineral oil origin.
C. Wastewater from industrial plants containing floatable
oils, fat or grease.
D. Any garbage that has not been properly shredded. Garbage
grinders may be connected to sanitary sewers from homes, hotels, institutions,
restaurants, hospitals, catering establishments or similar places
where garbage originates from the preparation of food in kitchens
for the purpose of consumption on the premises or when served by caterers.
E. Any waters or wastes containing iron, chromium, copper,
zinc and similar objectionable or toxic substances to such degree
that any such material received in the composite wastewater at the
wastewater treatment works exceeds the limits established by the Superintendent
for such materials.
F. Any waters or wastes containing odor-producing substances
exceeding limits which may be established by the Superintendent.
G. Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by the Superintendent
in compliance with applicable state or federal regulations.
H. Quantities of flow, concentrations or both which constitute
a slug, as defined herein.
I. Waters or wastes containing substances which are not
amenable to treatment or reduction by the wastewater treatment processes
employed or are amenable to treatment only to such degree that the
wastewater treatment plant effluent cannot meet the requirements of
other agencies having jurisdiction over discharge to the receiving
waters.
J. Any water or wastes which, by interaction with other
water or wastes in the public sewer system release obnoxious gases,
form suspended solids which interfere with the collection system or
create a condition deleterious to structures and treatment processes.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing floatable grease in excessive amounts as specified in §
212-26C, or any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the Superintendent. Any removal and hauling of the collected materials not performed by owners' personnel must be performed by currently licensed waste disposal firms.
Where pretreatment or flow equalizing facilities
are provided or required 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 Superintendent, the owner
of any property serviced by a building sewer carrying industrial wastes
shall install a suitable structure, together with such necessary meters
and other appurtenances in the building sewer to facilitate observation,
sampling and measurement of the wastes. Such structure, when required,
shall be accessibly and safely located and shall be constructed in
accordance with plans approved by the Superintendent. The structure
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 analysis of the
characteristics of waters and wastes, to which reference is made in
this Part 1, 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. Sampling methods, location,
times durations and frequencies are to be determined on an individual
basis subject to approval by the Superintendent.
[Amended 9-7-1982 by L.L. No. 6-1982]
No statement contained in this division shall
be construed as preventing any special agreement or arrangement between
the Village and any industrial concern whereby an industrial waste
of unusual strength or character may be accepted by the Village for
treatment. Any such special agreement shall be subject to and conform
with the provisions contained in any applicable state and/or federal
rules and regulations.
[Added 9-7-1982 by L.L. No. 6-1982]
The user shall notify the Village and the Westchester
County Department of Environmental Facilities (DEF) immediately upon
accidentally discharging wastes in violation of this Part 1. Within
15 days of the date of the occurrence, a detailed statement, in writing,
describing the causes of the accidental discharge and the measures
taken to prevent future occurrences shall be filed with the Village
and DEF. Such notification will not relieve users of liability for
any expense, loss or damage to the sewer system, treatment plant or
treatment process or for any fines imposed on the municipality under
applicable state and federal regulations.
