Stormwater and all other drainage shall be discharged
to such sewers as are specifically designated as combined sewers or
storm or to a natural outlet approved by the Commissioner and by the
Monroe County Health Department. Unpolluted industrial cooling water
or unpolluted process water may be discharged, on approval of the
Commissioner and the Monroe County Health Department, to a storm sewer,
combined sewer or natural outlet.
No person shall discharge or cause to be discharged
any stormwater, surface water, ground water, roof runoff, age, uncontaminated
cooling water or unpolluted industrial process water to any sanitary
sewer.
No person shall discharge or cause to be discharged
any of the following described water or wastes to any public sewers:
A.
Any gasoline, benzene, naphtha, fuel oil or other
flammable or explosive liquid, solid or gas.
B.
Any water or wastes 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 sewage-treatment
process, constitute a hazard to humans or animals, create a public
nuisance, or create any hazard in the receiving waters of the sewage-treatment
plant, including but not limited to cyanides in excess of two mg/1
as CN in the wastes as discharged to the public sewer.
C.
Any water or wastes having a pH lower than five point
five (5.5) or having any other corrosive property capable of causing
damage or hazard to structures, equipment and personnel of the sewage
works.
D.
Any water or wastes having a pH in excess of ten point
zero (10.0).
E.
Solid or viscous substances in quantities or of such
size as to be capable of causing obstruction to the flow in sewers,
or other interference with the proper operation of the sewage works
such as, but not limited to, ashes, cinders, sand, cement, mud, straw,
shavings, metal, glass, rags, feathers, tar, plastics, wood, hops,
spent grain, unground garbage, whole blood, paunch manure, hair and
fleshiness entrails, and paper dishes, cups, milk containers, either
whole or ground by garbage grinders.
[Amended 2-14-2006 by Ord. No. 2006-22]
No person shall discharge, or cause to be discharged
the following described substances, materials, water, or wastes to
any public sewer, if it appears likely in the opinion of the Commissioner
that such wastes can harm either the sewers, sewage-treatment process
or equipment, have an adverse effect on the receiving stream, or can
otherwise endanger life, limb or public property, or constitute a
nuisance. In forming his or her opinions as to the acceptability of
these wastes, the Commissioner will give consideration to such factors
as the quantities of subject wastes in relation to flows and velocities
in the sewers, materials of construction of the sewers, nature of
the sewage-treatment process, capacity of the sewage-treatment plant,
degree of treatability of wastes in the sewage-treatment plant, and
other pertinent factors. The substances are:
A.
Any liquid or vapor having a temperature higher than
150º F.
B.
Any water or waste containing fats, wax, grease or
oils, whether emulsified or not, in excess of 100 mg/l or containing
substances which may solidify or become viscous at temperatures between
32º F. and 150º F.
C.
Any garbage that has not been properly shredded. Garbage
grinders shall be unlawful except in homes, hotels, institutions,
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 for consumption off the premises
when served by caterers. The installation and operation of any garbage
grinder equipped with a motor greater than 3/4 horsepower shall
be subject to review and approval of the Commissioner.
D.
Any water or wastes containing strong acid, iron pickling
wastes or concentrated plating solutions whether neutralized or not.
E.
Any radioactive wastes or isotopes of such half-life
or concentration as may exceed limits established by applicable state
or federal regulations.
F.
Materials which exert or cause:
(1)
Unusual concentrations of inert suspended solids (such
as, but not limited to, fuller's earth, lime slurries and lime residues)
or of dissolved solids (such as, but not limited to, sodium chloride
and sodium sulfate).
(2)
Excessive discoloration (such as, but not limited
to, dye wastes and vegetable tanning solutions).
(3)
Unusual BOD, chemical oxygen demand, or chlorine requirements
in such quantities as to constitute a significant load on the sewage-treatment
works.
(4)
Unusual volume of flow or concentration of wastes
constituting "slugs" as defined herein.
G.
Water or wastes containing substances which are not
amenable to treatment or reduction by the sewage-treatment processes
employed, or are amenable to treatment only to such degree that the
sewage-treatment plant effluent cannot meet the requirements of other
agencies having jurisdiction over discharge to the receiving water.
A.
If any water or wastes are discharged, or are proposed to be discharged to the public sewers, which water or wastes contain the substances or possess the characteristics enumerated in § 97-12 of this article, and which, in the judgment of the Commissioner, may have a deleterious effect upon the sewage works, process, equipment or receiving water, or which otherwise create a hazard to life or constitute a public nuisance, the Commissioner shall:
B.
If the Commissioner permits the pretreatment or equalization
of waste flows, the design and installation of the plants and equipment
necessary to accomplish such pretreatment or equalization shall be
subject to the review and approval of the Commissioner, and subject
to the requirements of all applicable codes, ordinances and laws.
[Amended 2-14-2006 by Ord. No. 2006-22]
Where preliminary treatment or flow-equalizing
facilities are provided for any water or wastes, they shall be maintained
continuously in satisfactory and effective operation by the owner
at his or her expense.
[Amended 2-14-2006 by Ord. No. 2006-22]
The owner of any property serviced by a building
sewer carrying industrial wastes shall install a suitable control
manhole or other suitable and accessible sampling point in the building
server to facilitate observation, sampling and measurement of the
wastes. Said owner shall also be required to install such necessary
meters and other appurtenances as are required by the Commissioner.
Such sampling point shall be accessibly and safely located, and shall
be constructed in accordance with plans approved by the Commissioner.
The sampling point 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.
All measurements, tests, and analyses of the
characteristics of water 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, and shall be
determined at the sampling point provided, or upon suitable samples
taken at said sampling point. Sampling shall be carried out by customarily
accepted methods to reflect the effect of constituents upon the sewage
works and to determine the existence of hazards to life, limb and
property. (The particular analyses involved will determine whether
a twenty-four-hour composite of all outfalls of a premise is appropriate
or whether a grab sample or samples should be taken. Normally, but
not always, BOD and suspended-solids analyses are obtained from twenty-four-hour
(composites of all outfalls, whereas pH's are determined from periodic
grab samples.)
No statement contained in this article shall
be construed as preventing any special agreement or arrangement between
the City and any industrial concern whereby an industrial waste of
unusual strength or character may be accepted by the City for treatment,
subject to payment therefor by the industrial concern in accordance
with the Sewer Service Charge Code.
