[Adopted 5-25-1994 by Ord. No. 1994:667]

§ 160-6 Discharge of certain wastes prohibited.

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.

§ 160-7 Interceptors required.

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.

§ 160-8 Construction of interceptors.

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.

§ 160-9 Maintenance of interceptors.

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.[1]
