No person shall discharge, deposit, cause or allow to be discharged or deposited into the Delanco Sewerage Authority Collection System any wastewater which significantly contributes to a violation of any of the parameters in the Authority NJPDES permit, or which contains any of the following:
A. 
Oil and grease.
(1) 
Oil and grease from industrial facilities, in concentrations or amounts violating pretreatment standards; this includes petroleum based hydrocarbons as determined by silica gel absorption;
(2) 
Wastewater from commercial and/or industrial facilities containing floatable fats, wax, grease, or oil; and
(3) 
Total fats, wax, grease, or oil concentration of more than 100 mg/l, whether emulsified or not, or containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F. (0° C. and 65° C.) at the point of discharge into the treatment works.
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 treatment works or to the operation of the works; such materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides, and sulfides. Explosive and flammable mixtures shall also include any waste stream with a closed-cup flashpoint less then 60° C.
[Amended 1-9-2007 by Res. No. 2007-02]
C. 
Noxious materials. Pollutants which, either singly or by interaction with other wastes, are malodorous, are capable of creating a public nuisance or hazard to life or health, or are present in sufficient concentrations to prevent entry into the treatment works 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 treatment works, with no particle greater than 1/2 inch by 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 treatment works; 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. (Other materials may be specified at the discretion of the Superintendent.)
G. 
Excessive discharge.
[Amended 1-9-2007 by Res. No. 2007-02]
(1) 
Wastewater at an instantaneous flow rate in excess of 85 gallons per minute without preapproval from the Authority. Such preapproval will be contingent upon a capacity analysis of the down gradient sanitary sewer system.
(2) 
Wastewater at a flow rate that exceeds for any time period longer than 15 minutes more than five times the average daily flow rate of the industrial user during normal operations or containing such concentrations or quantities of pollutants that would cause a treatment process upset, inference, or loss of treatment efficiency.
H. 
Toxic discharge. Waters or wastes containing objectionable or toxic substances in sufficient quantity, either singly or by interaction with other pollutants, to result in pass-through, to cause interference with the treatment works plant, to constitute a hazard to humans or animals, to create a toxic effect in the receiving waters of the POTW, or to exceed standards promulgated by the EPA pursuant to Section 307(a) of the Act, or the NJDEP pursuant to Section 4 of the State Act (or the maximum permissible concentrations specified in Table I).
I. 
Stormwater. Discharge of stormwater, including surface and groundwater from sump pumps and cellar drains, into the collection system from any source; (optional: except existing combined sewers).
J. 
Discolored materials. Wastes with color which would cause the treatment works to exceed water quality color criteria.
K. 
Substances interfering with sludge management. Any substance which may cause the POTW's sludge to be unsuitable for reclamation and reuse or to interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program. In no case shall a substance discharged to the POTW cause the POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substances Control Act, or, to the extent practicable, the "New Jersey Guidelines for the Utilization and Disposal of Municipal and Industrial Sludges and Septage."
L. 
Corrosive wastes. Any waste which will cause corrosion or deterioration of the POTW; all wastes discharged to the treatment works must not have a pH value lower than 5.0 or greater than 10.0 standard units (unless the treatment works is specifically designed to accommodate such discharges); prohibited materials include, but are not limited to, acids, alkalies, sulfides, concentrated chloride and fluoride compounds, and substances which will react with water to form acidic or alkaline products with a pH value that does not fall within the range stated herein.
M. 
Heat. Heat in amounts which will inhibit biological activity in the treatment works, resulting in interference or causing damage, but in no case heat in such quantities that the temperature exceeds 65° C. (150° F.) at the treatment works and 40° C. (104° F.) at the POTW, unless the NJDEP, upon request of the POTW, approves alternate temperature limits.
N. 
Pathogenic bacteria (viable). Other than those normal to domestic sewage.
A. 
Tables IA and IB presents the maximum concentrations of certain pollutants allowable in wastewater discharges to the collection system and the POTW by any discharger. Dilution of any wastewater discharge for the purpose of satisfying these requirements shall be considered a violation of this chapter. The limits on certain pesticides, benzides, and PCB's in Table IA are (in conformance with the Final Toxic Effluent Standards published in the Federal Register) as follows (date references are in Final Toxic Effluent Standards published dates in the Federal Register):
(1) 
Polychlorinated biphenyls (PCBs): February 2, 1977.
(2) 
Standard for aldrin/dieldrin, benzidine DDT (DDD, DDE), endrin and toxaphene: January 12, 1977.
B. 
All users are limited by restrictions and prohibitions set forth in applicable state and federal regulations, including Categorical Pretreatment Standards, as promulgated.

NOTES:
* Discharges in excess of these limits will be considered by the Authority on a case-by-case basis provided proper application is made to the Authority and approval is granted prior to any discharge in excess of the limits shown.
** Discharges in excess of the limit shown will be subject to implementation of best management practices on a case-by-case basis provided proper application is made to the Authority and approval is granted prior to any discharge in excess of the limit shown.
*** This limit is based on readily available treatment technology and is subject to the imposition of best management practices approved by the Authority at such time as the quantity of this pollutant becomes a concern in the Authority's Sewerage Treatment Plant's effluent or sludge.
C. 
Sewer extensions specifications. Any industrial user adding a sewer extension to the Authorities’ collection system shall design the same in accordance with N.J.A.C. 5:21 et seq. and the Delanco Sewerage Authority Master Plan. The sewer extension design proposed by the industrial user shall be subject to an application review and approval by the Authority and any and all other controlling governmental boards or bodies having jurisdiction over the proposed sewer extension plan. Any proposed industrial user proposing a sewer extension that proposes a flow in excess of 85 gpm shall submit a down gradient capacity analysis in accordance with § 330-4 of this chapter.
[Added 1-9-2007 by Res. No. 2007-02]
Upon the effective date of the Federal Categorical Pretreatment Standard for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this chapter for sources in that subcategory, shall immediately supersede the limitations imposed under this chapter. Affected industrial users shall comply with such standards within the stated compliance deadlines. The Superintendent shall attempt to notify affected industrial users of the applicable reporting requirements under 40 CFR 403.12, but a failure to notify does not relieve such industries of the obligation to comply with such reporting requirements.
Federal Categorical Pretreatment Standards can be modified only through the federal regulatory mechanism available pursuant to 40 CFR 403.7.
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those in this chapter.
The Authority reserves the right to establish more stringent limitations or requirements on discharges to the collection system if deemed necessary to comply with objectives presented in Article I of this chapter.
[Amended 1-9-2007 by Res. No. 2007-02]
No user shall ever increase the use of process water or potable water to dilute a discharge as a partial or complete substitute to achieve compliance with the limitations contained in the Federal Categorical Pretreatment Standards, or in any other pollutant specific limitation developed by the Authority of the state.
