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.

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 toxic or poisonous substances shall not be present in any appreciable 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.

Iron	10

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.

Any noxious or malodorous gas, vapor or substance capable of creating a public or private nuisance.

Any water or waste containing phenols and/or orthocresols in excess of one one-hundredth part per million.

Any waste or wastes containing insoluble substances in excess of a daily average of 500 milligrams per liter.

(Deleted)

Any water or wastes having an average chlorine demand greater than 20 parts per million.

Any waters or wastes having a five-day biochemical oxygen demand (BOD) greater than 250 milligrams per liter.

Oils, fats or grease, except as may result from household, hotel or restaurant operation.

Rubbish or any garbage, including such kitchen wastes as have been ground or chopped by mechanical devices or appliances.

Milk, brewery or distillery waste in any form without approved pretreatment.

And in addition, any waste or substance which shall cause or result in:

Any waters or waste containing any color that cannot be removed from the waters or waste by the existing treatment system or process.

Any waters or wastes containing suspended solids exceeding a daily average of 250 milligrams per liter.

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.

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.

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.

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.

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.
