No person shall, without the appropriate permit, discharge directly
or indirectly into the borough's public sanitary sewer system any wastes or
wastewater which contains any of the following:
A. Oil and grease. Oil and grease from nonresidential facilities
in concentrations or amounts violating applicable pretreatment standards as
defined by the United States Environmental Protection Agency (hereafter "EPA")
or the New Jersey Department of Environmental Protection and Energy (hereafter
"DEPE"); this includes:
(1) Petroleum-based hydrocarbons as determined by silica
gel absorption.
(2) Wastewater from retail, commercial and/or industrial
facilities containing floatable fats, wax, grease or oil.
(3) Total fats, wax, grease or oil containing concentration
of more than one hundred (100) mg/l, whether emulsified or not, or containing
substances which may solidify or become viscous at temperatures between thirty-two
degrees and one hundred fifty degrees Fahrenheit (32º and 150º F.)
[zero degrees and sixty-five degrees Celsius (0º and 65º C.)] at
the point of discharge into the sewer system.
B. Explosive and/or flammable mixtures. Liquids, 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 sewer system or to the operation thereof.
Such materials include, but are not limited to, gasoline, kerosene, naptha,
benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides,
chlorates, perchlorates, bromates, carbides, hydrides and sulfides.
C. Noxious material. Noxious material and pollutants which,
either singly or by interaction with other wastes, are malodorous or capable
of creating a public nuisance or hazard to life or health or are present in
sufficient concentrations to prevent entry into the sewer system for its maintenance
and repair.
D. Improperly shredded garbage. Garbage that has not been
ground or comminuted to such a degree that all particles will be floating
or carried freely in suspension under flow conditions normally prevailing
in the sewer system, with no particle greater than one-half ( 1/2) inch
in any dimension. The discharge of any improperly shredded garbage is prohibited;
this prohibition does not apply to the use of garbage disposal units in private
dwellings whose only discharge is domestic wastewater.
E. Radioactive wastes. Prohibited except in conformance
with N.J.A.C. 7:28-11.2 (Disposal of radioactive materials-disposal by release
into sanitary sewerage systems).
F. Solid or viscous wastes. Solid or viscous wastes which
will or may cause obstruction to the flow in a sewer or otherwise interfere
with the proper operation of the sewer system. Prohibited materials include,
but are not limited to, grease, improperly shredded garbage, animal guts or
tissues, diseased human organs or tissue fluids, paunch manure, bones, hair,
hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand,
spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings,
rags, spent grains, spent hops, wastepaper, wood, plastic, tar, asphalt residues,
residues from refining or processing of fuel or lubricating oil and similar
substances.
G. Excessive discharge. Wastewater at a flow rate that exceeds
for any time period longer than fifteen (15) minutes more than five (5) times
the average daily flow rate of the nonresidential user during normal operation
or containing such concentrations or quantities of pollutants that, in the
judgment of the Superintendent of Public Works or Borough Engineer, would
cause a treatment upset, interference or loss of treatment efficiency.
H. Toxic discharge. Waters and wastes containing objectionable
or toxic substances in sufficient quantity, either singly or by interaction
with the other pollutants, to result in pass-through, to cause interference
with the sewer system or to constitute a hazard to humans or animals or to
exceed standards promulgated by the EPA or the DEPE.
I. Stormwater. Discharge of stormwater, including surface
and ground water, from sump pumps and cellar drains into the sewer system
from any source.
J. Discolored materials. Wastes with a color higher than
five hundred (500) units as per platinum cobalt standard.
K. Corrosive wastes. Any waste which will cause corrosion
or deterioration to the sewer system; all wastes discharged to the sewer system
must not have pH value lower than five point five (5.5) or greater than nine
point five (9.5) standard units; prohibited materials include, but are not
limited to, concentrated acids, alkalis, sulfides, chloride and fluoride compounds
and substances which will react with water to form acidic or alkaline products
which have a pH value that does not fall within the range stated herein.
Grease, oil and sand interceptors shall be provided when, in the opinion
of the Health Officer, Building Subcode Official or Borough Engineer, they
are necessary for the proper handling of liquid wastes containing grease in
excessive amounts or any flammable wastes, sand or other harmful ingredients,
except that such interceptors shall not be required for residential units.
All interceptors shall be of a type and capacity approved by the Health Officer,
Building Subcode Official or Borough Engineer 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.
Where installed, all grease, oil and sand interceptors shall be maintained
by the owner, at his expense, in continuously efficient operation at all times
and easily accessible for inspection.
