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.
A.
Grease, oil and sand interceptors shall be provided when, in the
opinion of the Director and/or Sewer Commission, they are necessary
for the proper handling of wastes containing grease in excessive amounts
or any flammable wastes, sand, grit and other harmful ingredients.
All interceptors shall be of a type and capacity approved by the Sewer
Commission and shall be located so as to be readily and easily accessible
for cleaning and inspection. Grease and oil interceptors shall be
constructed of impervious materials capable of withstanding abrupt
and extreme changes in temperature. They shall be of substantial construction,
watertight and equipped with easily removable covers, which, when
bolted in place, shall be gastight and watertight. Grease and oil
interceptors shall be constructed in any place or building having
a capacity to serve group meals.
B.
Where installed, all grease, oil, sand and grit interceptors shall
be maintained by the owner at his expense in continuous efficient
operation at all times. Materials collected shall not be reintroduced
into the sewage system.
A.
The admission into the public sewers of any waters or wastes having a five-day biochemical oxygen demand greater than 300 milligrams per liter by weight or containing more than 350 milligrams per liter by weight of suspended solids or containing any quantity of substance having the characteristics described in § 92-26 of this article or having an average daily flow greater than 2% of the average daily sewage flow of the sewer system shall be subject to the review and approval of the Sewer Commission.
B.
Where necessary in the opinion of the Sewer Commission, the owner
shall provide, at his expense, such preliminary treatment as may be
necessary to reduce the biochemical oxygen demand to 300 milligrams
per liter by weight or reduce objectionable characteristics or constituents
to within the maximum limits provided for in this section or control
the quantities and rates of discharge of such waters or wastes.
C.
Plans, specifications and any other pertinent information relating
to proposed preliminary treatment facilities shall be submitted for
the approval of the Sewer Commission, together with a letter from
the New York State Department of Health approving the proposed preliminary
treatment facilities, and no construction of such facilities shall
be commenced until said approvals are obtained in writing.
A.
Where preliminary treatment facilities are required for any waters
or wastes, no permit will be granted until such pretreatment units
have been placed in operation and have demonstrated their effectiveness
by test. The cost of such testing, sampling and analyzing shall be
borne by the waste contributor.
B.
Said preliminary treatment facilities shall be maintained continuously
and satisfactorily in effective operation by the owner at his expense.
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.
