[Amended 10-26-2021 by Ord. No. 11-2021]
Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the Superintendent and the New Jersey Department of Environmental Protection.
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sewers:
A. 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
B. 
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance or create any hazard in the receiving waters of the sewage treatment plant, including but not limited to cyanides in excess of two mg/l as CN in the wastes as discharged to the public sewer.
C. 
Any waters or wastes having a pH lower than 5.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
D. 
Solids 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 sewage works, such as but not limited to ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, manure, hair and fleshing, entrails and paper dishes, cups, milk containers, etc., either whole or ground by garbage grinders.
E. 
Any discharge that will produce an oxygen demand greater than could be expected from domestic sewage.
A. 
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely in the opinion of the Superintendent that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant and other pertinent factors.
B. 
A waste flow that may be initially acceptable to the City may in the future, without any change in the character of the waste or volume, become unacceptable by virtue of the enactment of stricter and more extensive prohibitions of deleterious substances, materials, waters or wastes. In such case, the City shall take action as provided in § 288-35 of this article.
C. 
The substances prohibited are:
(1) 
Any liquid or vapor having a temperature higher than 150° F. (65° C.).
(2) 
Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of 100 mg/l or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F. (0° C. and 65° C.).
(3) 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of 3/4 horsepower (0.76 horsepower metric) or greater shall be subject to the review and approval of the Superintendent.
(4) 
Any waters or wastes containing iron, chromium, copper, zinc and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
(5) 
Any waters or wastes containing phenols or other taste- or odor-producing substances, in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of the state, federal or other public agencies of jurisdiction for such discharge to the receiving waters.
(6) 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable state or federal regulations.
(7) 
Any waters or wastes having a pH in excess of 9.0.
(8) 
Materials which exert or cause:
(a) 
Unusual concentrations of inert suspended solids (such as but not limited to fuller's earth, lime slurries and lime residue) or of dissolved solids (such as but not limited to sodium chloride and sodium sulfate).
(b) 
Excessive discoloration (such as but not limited to dye wastes and vegetable tanning solutions).
(c) 
Unusual BOD, chemical oxygen demand or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
(d) 
Unusual volume of flow or concentration of wastes constituting slugs as defined herein.
(9) 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
A. 
If any waters or wastes are discharged or are proposed to be discharged to the public sewers, which waters contain the substances or possess the characteristics enumerated in § 288-34 of this article and which in the judgment of the Superintendent may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Superintendent may:
(1) 
Reject the wastes.
(2) 
Require pretreatment to an acceptable condition for discharge to the public sewers.
(3) 
Require control over the quantities and rates of discharge.
(4) 
Require payment to cover the added cost of handling and treating the wastes not covered by existing taxes or sewer charges under the provisions of § 288-40 of this article.
B. 
If the Superintendent permits the pretreatment or equalization of waste flows, the design and installation of the plants and equipment shall be subject to the review and approval of the Superintendent and subject to the requirements of all applicable codes, ordinances and laws.
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, 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 private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located so as to be readily and easily accessible for cleaning and inspection and shall be maintained by the owner in continuous, efficient operation at all times.
Where pretreatment or flow-equalizing facilities are provided or required for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole, together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this Part 1 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, and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. 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 building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property.
No statement contained in this article shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor, by the industrial concern.
[Amended 10-26-2021 by Ord. No. 11-2021]
Any developer, subdivider of land or other person, firm or corporation requiring the approval of the City as a condition precedent to approval of a subdivision by the City of Northfield Planning Board, or any other person seeking approval of sewers, laterals or other sewage collection and/or treatment facilities that it is intended will be incorporated into the City's sewerage system, or any other person requiring sewerage service for dwellings or other buildings not located and fronting on a presently existing and accepted municipal street, or fronting on a street so accepted but not presently serviced to the location of the property by the system of the City, shall be required to comply with all applicable sections of Ch. 288 herein set forth, and all other rules and regulations of the City, as a condition precedent to the approval of the City of Northfield.
All laterals, sewers, manholes, pumping stations, treatment facilities and other appurtenances required to be constructed in any new streets to be dedicated to the municipality, within the boundaries of a development or on any existing street within the City, shall be constructed by the applicant in conformity with this Part 1, subject to the City's inspection, and shall be constructed at the sole cost and expense of the applicant for all labor, material and supervision involved, including the cost of inspection by the City, and upon completion and acceptance by the City shall become the City's property, together with any and all easements or rights-of-way necessary for the effective operation of such collection system. The system shall be designed to connect to the existing public sewerage system at such point as shall be designated by the City.
Where enlargement of plant, facilities or extension of the City's system to such point of connection is involved and in the City's opinion the revenues to be derived from such development are either insufficient to warrant the expense of such extension or the probability of such revenues resulting from the development is speculative, or where by reason of limitations of law on the City's borrowing power or practical impediments to borrowing the needed funds to build such extensions or enlarge said plant the City deems it inadvisable or impractical to continue such extension, then the City may either refuse to construct the extension or construct the extension on terms involving cash or bonded payments by the developer as such payments make such extension practicable. In the event the City deems the potential revenues to be derived from the development to be speculative, the City may, in all events, require a corporate surety bond or escrow deposit in an amount sufficient in the City's opinion to guarantee the condition of the bond, which shall be conditioned for the payment by the applicant of the cost of any extensions or enlargements made necessary by reason of the development if the dwelling or other buildings in the development are not completed within a time to be specified.
