destroy or cause an obstruction to the flow in any sewer or which
may interfere with the proper operation of the sewage works.
e. Any waters, sewage or waste having a pH less than five point five
(5.5) or greater than ten point zero (10.0) or having any other corrosive
or detrimental property capable of causing damage or hazard to the
sewage works or personnel.
f. Any waters or wastes containing a toxic, poisonous or radioactive
substance in sufficient quantity to injure or interfere with any sewage
treatment process or to constitute a hazard to humans, animals or
marine life or to create any hazard in the receiving waters. The following

quantity of industrial or commercial process discharges in excess
of the following limits in milligrams per liter (mg/l) by weight.
Hydrogen sulfides shall not be present in any measurable concentration
in any waters or wastes.

Radioactive wastes or material may be discharged into a public
sewer if conditions I and II below are met and if either condition
III or IV is also met, provided that such discharges have also been
approved by any and all local, state and federal regulatory agencies
having jurisdiction:
|
Condition I: Such wastes must be readily soluble or dispersible
in water.
|
Condition II: The gross quantity of all radioactive materials
so discharged must not exceed one (1) curie per year.
|
Condition III: The daily quantity of any radioactive material
if diluted by the average daily volume of sewage discharged into the
system from the installation must not exceed the maximum concentrations
allowed by the regulations of the United States Atomic Energy Commission.
|
Condition IV: Daily quantities of radioactive materials up to
the maximum permitted by the United States Atomic Energy. commission
may be so discharged, provided that the total monthly quantities,
if diluted by the average monthly volume of sewage discharged from
the installation, do not exceed the concentrations permissible under
condition III above.
|
g. Any noxious or malodorous gas, vapor or substance capable of creating
a public or private nuisance.
h. Any water or waste containing phenols and/or orthocresols in excess
of one one-hundredth part per million.
i. Any waste or wastes containing insoluble substances in excess of
a daily average of 500 milligrams per liter.
k. Any water or wastes having an average chlorine demand greater than
20 parts per million.
l. Any waters or wastes having a five-day biochemical oxygen demand
(BOD) greater than 250 milligrams per liter.
m. Oils, fats or grease, except as may result from household, hotel
or restaurant operation.
n. Rubbish or any garbage, including such kitchen wastes as have been
ground or chopped by mechanical devices or appliances.
o. Milk, brewery or distillery waste in any form without approved pretreatment.
p. And in addition, any waste or substance which shall cause or result
in:
1. Chemical reaction, either directly or indirectly, with the materials
of construction to impair the strength or durability of any sewer
structure.
2. Mechanical action that will destroy or damage the sewer structure.
3. Restriction of hydraulic capacity of sewer structures.
4. Restriction of normal inspection or maintenance of sewer structure.
5. Placing of unusual demands of quantity or quality on the sewage treatment
equipment or process, plant or sewers.
6. Limitation of effectiveness of the sewage treatment process.
7. Danger to public health and safety.
8. Obnoxious conditions inimical to the public interest.
q. Any waters or waste containing any color that cannot be removed from
the waters or waste by the existing treatment system or process.
r. Any waters or wastes containing suspended solids exceeding a daily
average of 250 milligrams per liter.
5. The admission into the public sewers of any waters or wastes containing
any quantity of substance having the characteristics described in
subsection 4 of this section or having an average daily flow greater
than two percent of the average daily sewage flow of the Borough of
Morris Plains shall be prohibited unless approved by the Borough council.
Where necessary, the owner shall provide, at his expense, such preliminary
treatment as may be necessary, as determined by the Borough engineer,
to reduce the quality and quantity of such wastes to these limits.
Plans, specifications and any other pertinent information relating
to proposed preliminary treatment facilities shall be submitted for
the approval of the Borough engineer and of the department of health
of the state of New Jersey, and no construction of such facilities
shall be commenced until said approvals are obtained in writing.
6. Determination of exclusions of wastes. In determining whether any
waste discharge or proposed to be discharged into any public sewer
is to be excluded, consideration will be given to the quantity, time
or times, rate and manner of discharge, dilution and character of
the waste in question, the size of the sewer into which the waste
is to be discharged, the probable quantity of sewage or other wastes
likely in said sewer and other pertinent facts. Minute quantities
of a waste which would be objectionable in a larger quantity may be
accepted, if sufficiently diluted when and as discharged, or if the
quantity discharged is small as compared with the flow in the receiving
sewer; but any permission to discharge minute quantities of an otherwise
excluded waste shall be revocable at any time by the sewer supervisor.
7. Pretreatment facilities. At all premises where wastes or substances
specified to be excluded from public sewers by these regulations are
present and liable to be discharged directly or indirectly into said
sewers, suitable and sufficient piping layouts, oil, grease, sand
and flammable waste traps or separators, screens, steeling tanks,
diluting devices, storage or regulating chambers, treatment, cooling
or other equipment and devices shall be provided. These shall be maintained
and properly operated by the owner of the premises or his agent at
his expense to ensure that no waste or substance is discharged in
violation of the requirements of these regulations.
Such facilities for pretreatment of wastes or waters discharged
to public sewers shall be approved by the Borough Engineer and by
any or all state regulatory agencies having jurisdiction. The Borough
Engineer or state agency may require of an owner installing pretreatment
facilities plans, specifications and a description of the facilities
which are proposed.
|
On premises where any of the wastes or substances as described
in this Subsection 7 are present, the Borough Engineer may require
the owner to provide, operate and maintain at his (the owner's)
expense a sampling well or wells, flow measuring devices, manholes
or other appurtenances, all readily accessible, on the building sewer
or drain from said premises near the point where said sewer or drain
connects to the public sewer. By means of said sampling well or wells,
flow measuring devices or other appurtenances, the owner, occupants
of said premises, said Engineer or any public officer having legal
jurisdiction may secure samples of or examine the wastes being discharged
into the public sewer for the purpose of determining compliance or
noncompliance with the requirements of these regulations.
|
Every person who shall cause or permit any waters or wastes
to enter or pass into the Borough sewerage system shall make written
report to the Borough Engineer upon increasing the rate of flow of
waters or wastes or upon changing the process, products or nature
of the waters or wastes.
|
The Sewer Supervisor or his duly authorized representative shall
have the right to enter and inspect any part of the premises served
by public sewers upon which there may be reason to believe that violations
of the requirements of these regulations have occurred or are likely
to occur for the purpose of ascertaining the facts as to such violation
or suspected violation or of obtaining samples of wastes or, if inspecting
flow measuring devices or treatment facilities provided, to prevent
prohibited discharges.
|
8. All measurements, tests and analyses of the characteristics of waters
and wastes referred to herein 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,
whenever applicable. In the event that no special manhole has been
required, the control manhole shall be considered to be the nearest
downstream manhole in the public sewer to the point at which the branch
connection is connected.
9. All industrial users and any other users contributing more than 20,000
gallons per day shall, when required by the Borough Engineer, install,
operate and maintain an acceptable flow metering device and report
readings of said device to the Borough upon request.
