Such other information as requested.
The following discharges are prohibited:
Any unpolluted waters such as stormwater, groundwater, roof runoff, subsurface drainage or cooling water.
Any liquid or vapor having a temperature higher than that stipulated hereinafter.
Any water or waste which may contain soluble oil or grease or any water containing floatable fats, oils, greases or other substances that will solidify or become viscous at normal climatic conditions or impair the operation of the Authority's system.
Any gasoline, benzine, naphtha, fuel oil, motor oil, mineral spirits, commercial solvent or other flammable or explosive liquid, solid or gas.
Any water or wastes that contain hydrogen sulfide, sulphur dioxide or nitrous oxide in quantities higher than that stipulated herein.
Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, offal, plastics, wood, paunch manure, hair and fleshings, entrails, lime residues, beer or distillery slops, chemical residues, paint or ink residues, cannery waste bulk solids, unshredded garbage, antibiotic wastes, free mineral acid, concentrated pickling wastes or plating solutions or any other solid or viscous substance capable of causing obstruction to the flow or other interference with the proper operation of the Authority's system.
Any water or wastes containing toxic or poisonous substances in such concentrations as to constitute a hazard to humans or animals or to interfere with any sewage treatment process or to create any hazard in the receiving waters of the sewage treatment plant.
Wastes which will cause corrosive structural damage to the system.
Any waters containing suspended solids of such character and quantity that unusual provision, attention or expense is required to handle such materials at the sewage treatment plant.
Any noxious or malodorous gas or substance capable of creating a public nuisance or hazard to life or preventing entry into sewers for their maintenance, inspection and repair.
Any waters containing quantities of radium, naturally occurring or artificially produced radioisotopes in excess of presently existing or subsequently accepted limits for drinking water as established by the National Committee on Radiation Protection and Measuring.
Any concentrated dye wastes, spent tanning solutions or other wastes which are highly colored or wastes which are of unusual volume, concentration of solids or composition that may create obstruction to the flow in sewers or other interference with the proper operation of the system or the quality of the effluent from the system.
The following fixed upper limits of acceptable quantity (concentration) and characteristics of materials shall apply:
(milligrams per liter)
Acetylene generation sludge
Total chrome
Grease and soluble oils
Hydrogen sulfide
Iron (total)
Mineral acid (free)
Nitrous oxide
Oils, minerals
Sulphur dioxide
Zinc Concentration
Temperature, maximum
pH (allowable range)
5.5 to 9.0
Biochemical oxygen demand (BOD-five-day maximum)
350 ppm
Suspended solids, maximum
350 ppm
200 Co.-Pt. Units
The above-listed concentrations and characteristics may be altered by the Authority as required by regulatory agencies, treatment or reuse requirements or in the event of cumulative overload of the system.
Effluent limitations promulgated by the Federal Act shall apply in any instance where they are more stringent than those stipulated in this chapter. Under § 307(b) of the Act, federal pretreatment standards are designed to achieve two purposes: to protect the operations of publicly owned treatment works and to prevent the discharge of pollutants which pass through such works inadequately treated. Industrial dischargers subject to effluent guidelines issued under § 304(b) of the Act that are discharging pollutants to the Authority's system which are beyond the limits stated herein and beyond the treatment capability of the installed treatment facility are required to adopt the best practicable control technology currently available, as defined by the Administrator pursuant to § 304(b) of the Act.
The admission into the system of any water or wastes having a five-day biochemical oxygen demand (BOD) in excess of 350 parts per million by weight on a twenty-four-hour composite basis or for any grab sample having a five-day BOD in excess of 500 milligrams per liter will be subject to review by the Authority. Where necessary in the opinion of the Authority, the owner shall provide and operate, at his own expense, such pretreatment as may be required to reduce the biochemical oxygen demand to meet the above requirements.
The admission into the system of any waters or wastes having a suspended solids content in excess of 350 parts per million by weight on a twenty-four-hour composite basis or for any grab sample having a suspended solids content in excess of 500 milligrams per liter will be subject to review by the Authority. Where necessary in the opinion of the Authority, pretreatment may be required to reduce the suspended solids content to meet the above requirements.
The admission into the system of any waters or wastes in volumes, or with constituents, such that the existing dilution conditions in the system would be affected to the detriment of the Authority, shall be subject to review and approval of the Authority. Where necessary in the opinion of the Authority, pretreatment or equalizing units may be required to bring constituents or volume of flow within the limits previously described or to an otherwise acceptable level and to hold or equalize flows such that no peak flow conditions may hamper the operation of any unit of the system. Said equalization or holding unit shall have a capacity suitable to serve its intended purpose and be equipped with acceptable outlet control facilities to provide flexibility in operation and accommodate changing conditions in the waste flow.
Where pretreatment facilities are provided for any waters or waste, they shall be maintained continuously in satisfactory and effective operation by the owner, at his expense.
Representatives of the Authority, State of New Jersey Department of Environmental Protection, Federal Environmental Protection Agency and the respective municipalities shall have the right to enter all properties of the contributing industry for the purpose of inspection, observation, measurement, sampling and testing. The owner of any property that discharges a wastewater in excess of 50,000 gallons per day at any time during the year or has discharges exceeding the concentrations and characteristics listed hereinbefore shall be required to install a suitable control manhole on the building sewer on his property to facilitate inspection, observation, measurement, sampling and testing of wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Authority. The manhole shall be installed by the owner, at his own expense, and shall be so maintained by him as to be safe and accessible at all times. The manhole must be located on the industrial waste service connection with all sanitary wastes excluded.
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made herein shall be determined in accordance with the analytical methods described in Title 40 Federal Register Part 136 issued October 16, 1973, and shall be determined at the control manhole provided for above. 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, provided that there is no dilution of the wastewater at this location.
Subsequent to meeting the requirement for analysis of wastewater hereinbefore stipulated under the disposal requirements, the owner shall monitor the industrial discharge at such increments of time to ensure that the discharge requirements as hereinbefore stipulated are not being violated. Periodic reports on the constituents and characteristics of the wastewaters shall be submitted to the Authority substantiating compliance with this chapter. The frequency of reports shall be not less than quarterly.
The owner shall maintain such monitoring and testing equipment in good condition and shall keep accurate records showing the results of all sampling and testing conducted. These records shall be made available on request for inspection by the Authority and regulatory agencies.
Any approval by the Authority of a type, kind or capacity of an installation shall not relieve a person of the responsibility of revamping, enlarging or otherwise modifying such installation to accomplish an intended purpose, nor shall any fixed or verbal agreement as to limits of constituents or volumes of waters or wastes be considered as final approval for continuing operation. These limits will be subject to constant study and change as considered necessary to serve their intended purpose.
Any charges to be made for industrial cost recovery shall be computed, levied and collected in accordance with the provisions of Title II of the Federal Water Pollution Control Act Amendments of 1972 (P.L. 92-500, 33 U.S.C. § 1251 et seq.) and any amendments thereto and in accordance with Rules, Regulations and Procedures of the Environmental Protection Agency, Sections 35.928-1 and 35.935-13, and any amendments, additions and supplements thereto and thereof.
