Any user discharging wastewater into the Borough's
sewer system, when such wastewater contains pollutant concentrations
in excess of the surcharge limits listed below, will be subject to
a strength-of-waste surcharge for each pollutant concentration in
excess of the surcharge limits:

Users discharging wastewater to the Borough's
sewer system subject to the provisions of this chapter shall pay a
strength-of-waste surcharge, in addition to applicable volume charges,
equal to the sum of 1/10 of 1% (0.001 as a decimal) of the quarterly
sewer rental charge, for each mg/l by which the BOD, total suspended
solids, total phosphorus, or ammonia-nitrogen exceeds the surcharge
limits established under this chapter. Each surcharge amount shall
be considered a separate charge, additive to the quarterly sewer rental
billing amount of the user.
No user shall discharge or cause to be discharged,
directly or indirectly, any pollutant or wastewater which will interfere
with the operation or performance of the sewer system. These general
prohibitions apply to all users whether or not the users are subject
to any other pretreatment requirements or discharge limitations.
No user may discharge the following substances
to the sewer system:
A. Any 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 of the sewer
system. At no time shall two successive readings on an explosion hazard
meter, at the point of discharge into the system (or at any point
in the system) be more than 5% nor any single reading over 10% of
the lower explosive limit (LEL) of the meter. At no time shall the
closed cup flashpoint of the wastewater be less than 140° Fahrenheit.
Prohibited materials include, but are not limited to, the following
substances: gasoline, kerosene, naphtha, benzene, ethers, alcohols,
peroxides, perchlorates, bromates, and carbides.
B. Solid or viscous substances which may cause obstruction
of the flow in a sewer or other interference with the operation of
the sewer system, such as, but not limited to: animal guts or tissues,
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, waste paper, wood, plastics, gas, tar, asphalt residues,
residues from refining, or processing of fuel or lubricating oil,
mud, or glass grinding or polishing wastes.
C. Any wastewater having a pH less than 6.0 or higher
than 9.0, or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment, and/or personnel
of the sewer system.
D. Any wastewater containing toxic pollutants in sufficient
quantity, either singly or by interaction with other constituents
of the wastewater, to injure or interfere with any wastewater treatment
process, constitute a hazard to humans or animals, or create a toxic
effect in the receiving waters of the sewage treatment plant.
E. Any noxious or malodorous liquids, gases, or solids
which either singly or by interaction with other substances normally
present in the sewer system are sufficient to create a public nuisance
or hazard to life or are sufficient to prevent entry into the sewer
system for maintenance and repair.
F. Any substance which results in the formation or release
of toxic gases, vapors or fumes in a quantity that may cause acute
worker health and safety problems.
G. Any petroleum oil, nonbiodegradable cutting oil, or
products of mineral oil origin in amounts that will cause interference
or pass through, but in no case exceeding 20 mg/l.
H. Fats, oils, greases or waxes of animal or vegetable
origin in amounts which exceed 100 mg/l.
I. Any substance which may cause the sewage treatment
plant's effluent or any other product of the sewage treatment plant
such as residues, sludges, or scums, to be unsuitable for reclamation
and reuse or to interfere with the reclamation process. In no case
shall a substance discharge to the sewer system cause the sewage treatment
plant to be in noncompliance with sludge use or disposal criteria,
guidelines, or regulations affecting sludge use or disposal developed
pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxics
Substances Control Act, or state or federal criteria applicable to
the sludge management method being used.
J. Any substance which will cause the Borough to violate
its NPDES and/or state water quality management permit or applicable
receiving water quality standards.
K. Any wastewater with objectionable color which will
pass through the treatment plant, such as, but not limited to, dye
wastes and vegetable tanning solutions.
L. Any wastewater having a temperature which will inhibit
biological activity in the sewage treatment plant resulting in interference,
but in no case wastewater with a temperature at the point of discharge
into the sewer system which exceeds 140° F. (60° C.).
M. Any pollutants, including oxygen-demanding pollutants
(BOD, etc.) released at a flow rate and/or pollutant concentration
which will cause interference to the sewage treatment plant or interfere
with the operation of the sewer system. In no case shall a slug load
be discharged.
N. Any wastewater containing any radioactive wastes or
isotopes of such half-life or concentration as may exceed limits established
by the Borough or applicable state or federal regulations.
O. Any trucked or hauled wastewater or pollutants except
those discharged at points designated by the Borough.
P. Any wastewater which is incompatible with treatment
processes in use at the sewage treatment plant or which may cause
interference or pass through.
Q. Any wastewater containing any compounds or salts of
aldrin, dieldrin, endrin, lindane, methoxychlor, toxaphene, dichlorophenoxyacetic
acid, trichlorophenoxyproprionic acid, or other persistent herbicides,
pesticides or rodenticides.
R. Any garbage, except properly chopped garbage from
private residences only. Such garbage from private residences shall
not contain particles greater than 1/2 inch in length and width, or
1/2 inch in diameter. "Garbage" shall not be construed to mean industrial
waste.
The Borough reserves the right to develop local
limits regulating the discharge of pollutants to the sewer system.
These local limits will apply to all users of the sewer system, whether
or not the users are subject to any other pretreatment standards or
discharge limits.
