M. 
Any drainage from building construction;
N. 
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, bones, feathers, tar, plastic, wood, paunch manure, butcher's offal or any other solid or viscous substance which shall be capable of causing obstruction to the flow in any sewer or other interference with the proper operation of the sewer system or the treatment works;
O. 
Any water or waste having a pH lower than 6.5 or higher than 9.0 or having any corrosive property capable of causing damage or hazard to structures or equipment of the sewer system or the sewage treatment plant or to personnel engaged in operation and maintenance thereof. Examples of such prohibited materials include, but are not limited to acids, alkalis, concentrated chloride and fluoride compounds and substances which will react to water to form acidic or alkaline products; and
P. 
Any water or waste containing any toxic substance in quantity sufficient to constitute a hazard to humans or animals or to interfere with the biochemical processes of the treatment works or that will pass through the treatment works in such condition so that it will exceed state, federal or other validly existing requirements for the receiving stream.
A. 
It shall be presumed necessary for the proper handling of liquid wastes containing floatable grease, flammable wastes, sand, grit, solids, and other substances that may be harmful to the building drainage system, municipal sewer system or publicly owned treatment works and operation thereof, that interceptors (including grease, oil and sand interceptors) be installed in and required for all nonresidential establishments in the Borough. This presumption may be overcome and the requirement waived by the Borough Engineer upon a showing by the owner that the likelihood of the establishment discharging harmful substances into the sewer is de minimis. Examples of establishments where such a showing might be established include, but are not limited to, apparel and card shops. For purposes of this section where a building contains both residential and nonresidential uses, it shall be considered a nonresidential establishment.
B. 
All types and classes of interceptors shall be designed, constructed, installed and maintained in accordance with Chapter 6 of the National Standard Plumbing Code of 1987, as amended and supplemented through the DCA.
C. 
All interceptors shall be located as to be readily and easily accessible for cleaning and inspection. In the case of restaurants, catering establishments, hotels, cafeterias, gasoline stations and garages, and other establishments where required by the Borough Engineer because of the volume and/or type of waste(s) likely to be discharged by the establishment, interceptors may be required to be located outside.
D. 
The owner shall be responsible for proper removal and disposal of material retained by the interceptor, and shall maintain records of the dates and means of disposal, which are subject to inspection by the Borough Engineer or authorized agent. Any removal and hauling of collected materials not performed by the owner or his personnel shall be performed by licensed waste disposal firms. Interceptors shall be maintained continuously in satisfactory and effectively operating condition at all times by the owner at his sole cost and expense.
E. 
In the event the volume of waste from an establishment changes such that the interceptor is improperly sized, at his sole cost and expense, the owner shall cause a new interceptor to be installed and approved by the Borough Engineer or authorized agent.
The following are minimum requirements relative to the admission of industrial wastes into the municipal sewer system:
A. 
Any person desiring to make a connection to the municipal sewer system into which industrial wastes shall be discharged, shall file with the Borough a data sheet, to be furnished by the Borough Engineer, which shall supply pertinent information, including effluent data and estimated quantity of flow with respect to industrial wastes proposed to be discharged into the municipal sewer system.
B. 
Any person discharging industrial wastes into the municipal sewer system shall, when required by the Borough Engineer or authorized agent, construct and thereafter properly maintain at his own expense a suitable control manhole to facilitate observation, measurement and sampling of waste material. Any such control manhole shall be constructed at an accessible, safe, suitable and satisfactory location in accordance with plans approved by the Borough Engineer or authorized agent prior to commencement of construction.
C. 
Industrial wastes being discharged into the municipal sewer system shall be subject to periodic sampling, inspection and determination of character and concentration. Such sampling, inspection and determination shall be made by the Borough Engineer or authorized agent as frequently as may be deemed necessary. Representative samples for a full working day shall be obtained by taking hourly samples and compositing them in accordance with the flow at the time of sampling. Sewage sampling facilities shall be accessible to the Borough Engineer or authorized agent at all times. Due care shall be exercised in the collection and preservation of all samples to insure as nearly a natural state as possible, including refrigeration of all samples which are intended for analysis by biochemical methods.
D. 
The owner shall be responsible for the cost of analysis of samples of industrial wastes as required by the Borough Engineer. Laboratory methods used in the analysis of samples of industrial wastes shall be those set forth in the Standard Methods.
E. 
Any owner of improved property who is discharging industrial wastes into the municipal sewer system and who contemplates a change in the method of operation which will alter the type, quantity or frequency of discharge of industrial wastes being discharged into the sewer system shall notify the Borough Engineer or authorized agent in writing at least 10 days prior to the anticipated consummation of such change. No change shall be permitted unless approval therefor is granted by the Borough Engineer or authorized agent.
F. 
Any new source significant indirect user (SIU) as defined in N.J.A.C. 7:14A-1 et seq. shall obtain an NJDEP/SIU permit prior to commencing discharge into the treatment works.
G. 
Where any federal categorical pretreatment standard applicable to a particular industrial subcategory is more stringent than the effluent limitations imposed by this chapter for sources in that subcategory, the user shall adhere to the applicable federal standard. Any user discharging industrial wastes subject to federal categorical pretreatment standards shall, at a minimum, comply with the reporting requirements of 40 CFR 403.12.
H. 
All retail food establishments, catering establishments, commercial food preparation facilities shall maintain their sewage works with treatments of microorganisms. The microorganisms shall be of a type approved by the Borough Engineer and shall be applied in accordance with the manufacturer's recommendations and specifications. Records shall be maintained by the establishment detailing the dosing rate of the microorganism product being used.
[Added 4-5-1993 by Ord. No. 5-93]
No person shall cause the discharge of slugs of water or wastes. Each person producing a discharge into the municipal sewer system at a rate of in excess of 40,000 gallons in any one day shall construct and maintain at his own expense a suitable flow-control facility to insure equalization of discharge over a twenty-four-hour period. This facility shall have a capacity of at least 50% of the total normal volume of a twenty-four-hour production period, and the outlet to the sewer shall be equipped with a rate of discharge controller or other approved device, the regulation of which shall be directed by the Borough.
