No person 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 that stormwater
runoff from limited areas, which stormwater may be polluted at times,
may be discharged to the sanitary sewer by permission of the Superintendent.
No person shall discharge or cause to be discharged
any of the following described waters or wastes to any public sewers:
A. Any gasoline, benzene, naphtha, fuel oil, or other
flammable or explosive liquid, solid, or gas which by reason of its
nature or quantity is, or may be, sufficient either alone or by interaction
with other substances to cause fire or explosion or be injurious in
any other way to the POTW or to the operation of the POTW.
B. Any waters containing toxic or poisonous solids, liquids,
or gases in sufficient quantity, either singly or by interaction with
other wastes, to injure or interfere with any waste treatment process,
constitute a hazard to humans or animals, create a public nuisance,
or create any hazard in the receiving waters of the wastewater treatment
plant.
C. Any 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 the wastewater works.
D. Solid or viscous substances in quantities or of such
size capable of causing obstruction to the flow in sewers or other
interference with the proper operation of the wastewater facilities,
such as, but not limited to, ashes, bones, cinders, sand, mud, straw,
shavings, metal, glass, rags, feathers, tar, plastics, wood, unground
garbage, whole blood, paunch manure, hair and fleshings, entrails
and paper dishes, cups, milk containers, etc., either whole or ground
by garbage grinders.
The following described substances, materials,
waters or wastes shall be limited in discharges to municipal systems
to concentrations 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, or public property or constitute a nuisance. The Superintendent
may set limitations lower than the limitations established in the
regulations below if in his or her opinion such more severe limitations
are necessary to meet the above objectives. In forming his or her
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.) or in such quantities that the temperature at the
treatment works influent exceeds 104º F. (40º C.).
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 (see §
193-2). 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 as shown in Appendix A or as set in a categorical pretreatment standard.
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 applicable local,
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.
K. Any substance which may cause the POTW's effluent
or any other product of the POTW, such as residues, sludge, or scums,
to be unsuitable for the reclamation process where the POTW is pursuing
a reuse and reclamation program. In no case shall a substance discharged
to the POTW cause the POTW to be in noncompliance with sludge use
or disposal criteria, guidelines or regulations affecting sludge use
or disposal development pursuant to the Solid Waste Disposal Act,
the Clean Air Act, the Toxic Substance Control Act, or state criteria
applicable to the sludge management method being used.
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. §
193-27C, 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 so as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner 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 the owner's 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 or her 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 or her expense and shall be
maintained by him or her so as to be safe and accessible at all times.
The Superintendent may require a user of sewer
services to provide information needed to determine compliance with
this chapter. These requirements may include:
A. Wastewater discharge peak rate and volume over a specified
time period.
B. Chemical analyses of wastewaters.
C. Information on raw materials, processes, and products
affecting wastewater volume and quality.
D. Quantity and disposition of specific liquid, sludge,
oil, solvent or other materials important to sewer use control.
E. A plot plan of sewers on the user's property showing
sewer and pretreatment facility location.
F. Details of wastewater pretreatment facilities.
G. Details of systems to prevent and control the losses
of materials through spills to the municipal sewer.
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. Sampling methods, locations,
times, durations and frequencies are to be determined on an individual
basis subject to approval by the Superintendent.
Special agreements and arrangements between
the municipality and any persons or agencies may be established when,
in the opinion of the municipality, unusual or extraordinary circumstances
compel special terms and conditions. Acceptance of such waste shall
not cause the POTW to violate its SPDES permit or the receiving water
quality standards or any pretreatment regulations promulgated by USEPA
or NYSDEC in accordance with Section 307 of PL 95-217.
