No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, cooling
water, impounded water or unpolluted industrial process waters to
any sanitary sewer without written permission of the Sewer Commission.
Except as hereinafter provided, no person shall discharge or
cause to be discharged any of the following described waters or wastes
to any public sewer:
A. Any liquid or vapor having a temperature lower than 32° F. or
higher than 150° F.
B. Any water or waste which may contain more than one 100 milligrams
per liter by weight of fats, oils or grease.
C. Any gasoline, benzene, naphtha, fuel oil, waste petroleum products
from automotive service stations or garages or other flammable or
explosive liquid, solid or gas.
D. Any garbage that has not been properly shredded.
E. Any ashes, cinders, sand, mud, grit, straw, offal, shavings, metal,
glass, rags, feathers, tar, plastics, wood, sawdust, manure or other
solid or viscous substance capable of causing obstruction of the flow
in sewers or other interference with the proper operation of the sewage
system, in the opinion of the Director and/or Sewer Commission.
F. Any water or wastes having a pH lower than 6.0 or higher than 9.0
or having any other corrosive property capable of causing damage or
hazard to structures, equipment and personnel of the sewage system,
in the opinion of the Director and/or Sewer Commission.
G. Any water or wastes containing a toxic or poisonous substance in
sufficient quantity to injure or interfere with any sewage treatment
process, constitute a hazard to humans or animals or create any hazard
in the sewage system, in the opinion of the Director and/or Sewer
Commission.
H. Any water or wastes containing suspended solids of such character
and quantity that unusual attention or expense is required to handle
such materials at the sewage treatment plant.
I. Any noxious or malodorous gas or substance.
J. Any radioactive wastes or isotopes of such half-life or concentration
as may exceed limits established by the Director in compliance with
applicable state or federal regulations.
When required by the Sewer Commission, the owner of any property
served by a building sewer carrying commercial or industrial wastes
shall install a suitable control manhole in the building sewer to
facilitate observation, sampling and measurement of the wastes. Such
manhole, when required, shall be conveniently and safely located.
It is to be constructed in accordance with plans approved by the Sewer
Commission. 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 water and wastes to which reference is made in §§
92-26 and
92-28 shall be determined in accordance with Standard Methods for the Examination of Water and Sewage or with methods approved by the New York State Department of Health and may be determined at the control manhole provided for in §
92-30 or upon suitable samples taken at said manhole. In the event that no special manhole has been required, the control manhole may be considered to be the nearest downstream manhole in the public sewer to be the point at which the building sewer is connected. If, in the judgment of the Director, analyses must be performed which are beyond the scope of the laboratory at the sewage treatment plant, these analyses shall be performed at a laboratory designated by the Director, and the costs of these analyses shall be borne by the owner.
No statement contained in this section shall be construed as
preventing any special agreement or arrangement between the Sewer
Commission and any industrial, commercial or domestic concern whereby
waste which is of unusual strength or character can be accepted by
the Sewer Commission for treatment subject to payment therefor by
such concern.
