The discharge of excessive amounts of unpolluted water or waste
to a sanitary sewer is expressly prohibited. The Board reserves the
right to define the amount it deems excessive in each particular instance.
The discharge of garbage to the public sanitary sewage system
is expressly prohibited unless the garbage is first properly shredded.
No sanitary sewage or industrial waste from any property other than that for which a connection permit has been issued as provided in Article
IX hereof shall be discharged to the public sanitary sewage system. No industrial waste shall be discharged to the public sanitary sewage system by an industry without a special industrial waste discharge permit obtained in accordance with Article
IV hereof.
No person shall discharge to the public sanitary sewage system
any sanitary sewage or industrial wastes having any of the following
characteristics:
A. Wastes containing liquids, solids or gases which by reason of their
nature or quality may cause fire, explosions, or be in any other way
injurious to persons, the structures of the public sanitary sewage
system or its operation.
B. Wastes having a temperature in excess of 150° F. or less than
32° F.
C. Wastes having a pH lower than 5.5 or higher than 9.0 or having any
corrosive properties capable of causing damage or hazards to structures,
equipment or personnel of the public sanitary sewage system. Where
the Board deems it advisable, it may require any person discharging
industrial wastes to install and maintain, at his own expense, in
a manner approved by the Board or its designated representative, a
suitable device to continuously measure and record the pH of the wastes
so discharged.
D. Wastes containing any noxious or malodorous gas or substance which,
either singly or by interaction with sewage or other wastes, is, in
the opinion of the Board, likely to create a public nuisance or hazard
to life, or prevent entry to sewerage structures for their maintenance
and repair.
E. Wastes containing ashes, cinders, sand, mud, straw, shavings, metal,
glass, rags, feathers, tar, plastics, wood, hair, chemical or paint
residues, greases, lime slurry or viscose materials of such character
or in such quantity that, in the opinion of the Board, they may cause
an obstruction to the flow in the sewers or otherwise interfere with
the proper operations of the public sanitary sewage system. Attention
is called to the fact that the maximum permissible concentration will
vary throughout the public sanitary sewage system depending upon the
size of the particular interceptor sewer receiving the same and the
flows therein.
F. Wastes containing insoluble, nonflocculent substances having a specific
gravity in excess of 2.65.
G. Wastes containing soluble substances in such concentration as to
cause the specific gravity of the waste to be greater than 1.1.
H. Wastes containing any of the following substances in solution or
in suspension in concentrations exceeding those shown in the following
table:

I. Wastes containing more than 100 mg/l by weight of fat, oil, or grease.
J. Wastes containing more than 10 mg/l of any of the following gases:
hydrogen sulfide, sulfur dioxide, nitrous oxide, or any of the halogens.
K. Wastes containing gases or vapors, either free or occluded, in concentrations
toxic or dangerous to humans or animals.
L. Wastes containing toxic substances in quantities sufficient to interfere
with the biochemical processes of the sewage treatment works or that
will pass through the treatment process and still exceed the state
and federal requirements for the receiving stream.
M. Wastes containing toxic radioactive isotopes without a special permit.
N. Wastes at a flow rate and/or pollutant discharge rate which is excessive
over relatively short time periods.
O. In addition, waste discharge limitations, as outlined in ALCOSAN's
pretreatment requirements, must be adhered to.
