No person shall discharge or cause to be discharged
any stormwater, surface water, groundwater, roof runoff, subsurface
drainage, uncontaminated cooling water or unpolluted industrial process
waters to any sanitary sewer.
Stormwater and all other unpolluted drainage
shall be discharged to such sewers as are specifically designated
as storm sewers, or to a natural outlet. Uncontaminated industrial
cooling water or unpolluted industrial process waters may be discharged
on approval of the Director and upon obtaining a DEC permit to a storm
sewer or natural outlet.
No person shall discharge or deposit or cause
to allow to be discharged or deposited into the wastewater treatment
system any wastewater which contains the following:
A. Flammable or explosive mixtures. Liquid, solids or
gases which by reason of their nature or quantity are, 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
wastewater treatment system or to the operation of the system. At
no time shall there be discharged any wastestream with a closed cup
flashpoint of less than 140º F. or 60º C. using the test
methods specified in 40 CFR 261.21. Prohibited materials include,
but are not limited to, gasoline, kerosene, naphtha, benzene, fuel
oil, crank case oil, toluene, xylene, ethers, alcohols, ketones, aldehydes,
peroxides, chlorates, perchlorates, bromates, carbides, hydrides and
sulfides.
B. Toxic substances. Any toxic substances in amounts
exceeding standards promulgated by the Administrator of the United
States Environmental Protection Agency pursuant to Section 307(a)
of the Act, and chemical elements or compounds, phenols or other taste
or odor producing substances, or any other substances which singly
or by interaction with other wastes are not susceptible to treatment
or which may interfere with the biological processes or efficiency
of the wastewater treatment system, or that will pass through the
system without being treated to the required degree.
C. Corrosive wastes. Any waste which will cause corrosion
or deterioration of the wastewater treatment system. All wastes discharged
to the public sewer system must be a pH value in the range of six
to 10 standard units. Prohibited materials include, but are not limited
to, acids, sulfides, concentrated chloride and fluoride compounds
and substances which will react with water to form acidic products.
[Amended 5-10-1999 by L.L. No. 3-1999]
D. Solid or viscous wastes. 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 treatment system such as, but not limited to, ashes,
cinders, sand, mud, straw, shavings, metal, glass, rags, feathers,
tar, plastics, wood, unground garbage, whole blood, hair and fleshings
or hides, animal guts or tissues, entrails, bones, spent lime, stone
or marble dust, grass clippings, spent grains, spent hops, waste paper,
asphalt residues, residues from refining or processing of fuel or
lubricating oil and similar substances. This prohibition includes
any wastewater which by interaction with other waters or wastes in
the public wastewater treatment system forms suspended solids which
obstruct the flow in the sewer or create a condition that interferes
with the proper operation of the wastewater treatment system.
E. Oil and grease. Any wastewater containing fats, wax,
grease or oils, whether emulsified or not, or containing substances
which may solidify or become viscous at temperatures between 32º
F. and 150º F. (0º C. and 65º C.), and be determined
by the Director to be potentially harmful to the operation and efficiency
of the POTW.
F. Excessive temperature. Any wastewater which exceeds
a temperature of 150º F. (65º C.) or which causes the temperature
of the influent to the wastewater treatment works to exceed 104º
F. (40º C.).
G. Improperly shredded garbage. Garbage that has not
been ground or comminuted to such a degree that all particles will
be carried freely in suspension under flow conditions normally prevailing
in the public sewers.
H. Noxious materials. Noxious or malodorous solids, liquids
or gases, which either singly or by interaction with other wastes
are capable of creating a public nuisance or hazard to any form of
life, or are or may be sufficient to prevent entry into a sewer for
its maintenance and repair.
I. Radioactive wastes. Radioactive wastes or isotopes
of such half-life or concentration that they do not comply with regulations
or orders issued by the appropriate authority having control over
their use and/or which will or may cause damage or hazards to the
wastewater treatment system or personnel operating the system.
J. Excessive discharge rate. Quantities of wastewater
flow, concentrations, or both, which constitute a slug as defined
herein.
K. Discolored material. Wastes with color such as but
not limited to dye water or vegetable tanning solution that are not
removable by the treatment process.
L. Wastes with unusually high biochemical oxygen demand,
chlorine demand, total suspended solids, phosphorus or ammonia nitrogen
levels except when a surcharge agreement has been effected.
M. Any other wastes, which in the opinion of the Director
may be detrimental to the maintenance and operation of the wastewater
treatment system or may affect the sewage treatment process to the
extent that the effluent cannot meet the requirements of other agencies
having jurisdiction over discharge to the receiving waters. In forming
his opinion as to the acceptability of wastes, the Director will give
consideration to such factors as the quantities of such wastes in
relation to flows and velocities in the sewers, materials of construction
of the sewers, nature of the wastewater treatment process, capacity
of the wastewater treatment works, degree of treatability of wastes
in the wastewater treatment works and other pertinent factors.
