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 stormwater runoff from limited
areas, which stormwater may be polluted at times, may be discharged
to the sanitary sewer by permission of the Superintendent.
Stormwater other than that exempted under §
435-24 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.
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. Any garbage that has not been properly shredded. (See the definition of "properly shredded garbage" in §
435-2.) 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. 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.
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 oil in excessive amounts, as specified in §
435-27A(3), 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 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 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. Wastewaters 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 of 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 the USEPA
or NYSDEC in accordance with Section 307 of P.L. 95-217.
