A. 
No user shall contribute or cause to be contributed, directly or indirectly, to the POTW any pollutant or wastewater which will interfere with the operation or performance of the POTW. These general prohibitions apply to all such users of the POTW whether or not the user is subject to Federal Categorical Pretreatment Standards or any other federal, state or local pretreatment standards or requirements.
B. 
No user shall contribute the following substances to any POTW:
(1) 
Any 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 to be injurious in any other way to the POTW or to the operation of the POTW. At no time shall the atmosphere in a private sewer leading to a POTW structure exceed 25% of the lower explosive limit (LEL) unless the user can demonstrate that such a discharge does not create at the point of discharge into the POTW or at any other point in the POTW a reading over 10% LEL as measured by an explosimeter. Prohibited 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 and any other substances which can create a fire or explosion hazard to the POTW.
(2) 
Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities, such as but not limited to grease, garbage with particles greater than 1/2 inch in any dimension, animal guts or tissues, 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, plastics, gas, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes or any material which can be disposed of as trash.
(3) 
Any wastewater having a pH less than 7.0 or higher than 9.0, as measured by a grab sample or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the POTW.
(a) 
No industrial user measuring pH continuously at the point of discharge shall discharge wastes having a pH lower than 7.0 or higher than 9.0 at any time except for a period not to exceed a total of five minutes in any one-hour period. In the event that a periodic discharge of a pH lower than 7.0 or higher than 9.0 for a period exceeding five minutes occurs, the industrial user must demonstrate that the pH will not exceed the range of 7.0 to 9.0 at a downstream point designated by the Township. In no case may the industrial user's discharge contain a pH less than 5.0 at the point of discharge into the POTW.
(b) 
In the event that the influent wastewater flow arriving at a treatment plant is outside the pH range of 7.0 to 9.0, the Township may limit industrial users of the treatment plant to a pH range of 7.0 to 9.0, upon oral or written notice, for as long as the Township deems necessary.
(4) 
Any wastewater containing toxic pollutants which may, either singly or by interaction with other pollutants, injure, adversely affect or interfere with any wastewater treatment process; or constitute a hazard to humans or other biota or may create an adverse effect in the receiving waters of the POTW, as determined through biomonitoring conducted on POTW's effluent or through in-stream monitoring; or violate any provision of the Federal Clean Air Act (42 U.S.C. § 7401 et seq.), as amended, or local air quality regulations.
(5) 
Any noxious or malodorous liquids, gases or solids which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life or may result in toxic gases, vapor or fumes or are sufficient to prevent entry into the POTW for maintenance and repair without respiratory protection or other personal safety equipment.
(6) 
Any substance which may cause the POTW's effluent or any other product of the POTW, such as residues, sludges or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. 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, nor 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 state criteria applicable to the sludge management methods being used by the Township or city, as applicable.
(7) 
Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards.
(8) 
Any wastewater with objectionable color not removed in the treatment process, such as but not limited to dye wastes and vegetable tanning solutions.
(9) 
Any wastewater having a temperature which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the POTW which exceeds 60° C. (140° F.) or which shall cause the wastewater entering the POTW treatment plant to exceed 40° C. (104° F.).
(10) 
Any pollutants, including oxygen-demanding pollutants (BOD, etc.) and suspended solids released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference or pass-through to the POTW. In no case shall a slug load have a flow rate or contain a concentration or quantities of pollutants that exceed for any time period longer than 15 minutes more than five times the average twenty-four-hour permitted concentration, quantities or flow during normal operation.
(11) 
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by the Township or appropriate control authority in compliance with applicable state or federal regulations.
(12) 
Any wastewater which causes a hazard to human life or creates a public nuisance.
(13) 
Any wastewater containing motor oils or lubricants removed from vehicles or other machinery.
(14) 
Any wastewater containing substances which may solidify or become viscous at temperatures between 32° F. and 150° F.
(15) 
Any sludges, septage or holding tanks without prior written approval of the Department.
(16) 
Any wastewater which, because of its chemical nature or composition, causes the sewer atmosphere to contain airborne chemical concentrations in exceedance of concentrations established by the United States Department of Labor, Occupational Safety and Health Administration (OSHA), under 29 CFR 1910, regardless of duration of exposure experienced by any individual, whether a Department or contractor's employee, unless written authorization is granted by the Commissioner.
(17) 
Wastewater which may create a fire or explosive hazard in the POTW, including but not limited to wastewater with a closed-cap flashpoint of less than 140° F. using the test methods specified in 40 CFR 261.21.
(18) 
Any wastewater which, alone or in conjunction with any other discharges, causes foam anywhere in the treatment plant or its effluent.
C. 
In addition, the following activities are prohibited:
(1) 
No person shall discharge wastewater, pollutants, chemicals or any other substance or contaminant into street inlets or through sewer manholes without the prior written approval of the POTW.
(2) 
No person who generates wastewater at one property shall discharge it at another property without prior written approval from the POTW.
(3) 
No person shall discharge wastewater in quantities or at rates of flow which may have an adverse or harmful effect on or overload the appropriate control authority's or City's sewerage system or wastewater treatment plants or cause excessive or additional treatment costs or render inaccurate or interfere with the function of sewer metering devices.
(4) 
No person shall discharge a wastewater flow contributing greater than 42 pounds per day of five-day biochemical oxygen demand or contributing greater than 30 pounds per day of suspended solids or having a volume in excess of 50,000 gallons per day without prior written approval of the appropriate control authority.
(5) 
No person shall store or handle any material, including hazardous substances defined by CERCLA, in any area draining to any control authority sewer system, because discharge or leakage from such storage or handling may create an explosion hazard in the sewer system or treatment plant or may constitute a hazard to human beings or animals or the receiving stream or in any other way may have a deleterious effect upon the wastewater treatment facilities. Such storage or handling shall be subject to review by the appropriate control authority and shall require a spill control plan with reasonable safeguards to prevent discharge or leakage of such materials into the sewers.
(6) 
Industrial users processing regulated waste streams through their pretreatment facilities shall not bypass such pretreatment facilities unless they notify the appropriate control authority in writing and obtain prior written approval from such control authority.
(7) 
No person shall increase the use of potable water, groundwater, rainwater, river water or process water or in any way attempt to dilute an effluent as a partial or complete substitute for adequate treatment to achieve compliance with any pretreatment standards or requirements.
All users shall comply with all provisions contained in the general pretreatment regulations (40 CFR 403), as amended, and, if applicable, National Categorical Pretreatment Standards (40 CFR Chapter I, Subchapter N), as amended. Any limitations imposed under the general pretreatment regulations or the National Categorical Pretreatment Standards which are more stringent than the limitations in this chapter shall supersede the limitations imposed under this chapter.
Where the wastewater collection system within the Township achieves consistent removal of pollutants limited by federal pretreatment standards, the Township by the appropriate control authority, as its designated agent, may apply to the approval authority for modification of specific limits in the federal pretreatment standards of an industrial user or a whole category, these will be defined as "local limits" and reviewed by the regional director of EPA.

(2) 
The Township and each control authority reserves the right to modify this list of materials prohibited from entering the POTW as may become necessary by virtue of new state or federal regulations.
(3) 
Any toxic organic present at a level of 0.01 mg/l or greater must be monitored and reported.
C. 
Chlorine and ammonia. The free chlorine and/or free ammonia content of the waste shall be limited to five mg/l at any time as shown by grab sample. In particular instances where a mist-free atmosphere, as needed during inspection and maintenance of a sewer or to protect the POTW, is otherwise not attainable, the Township may direct the user to further reduce its discharge of chlorine and/or ammonia, either on a temporary or permanent basis, so as to eliminate formation of mist, in order to permit such inspection and maintenance and protect the POTW.
D. 
Hydrogen sulfide. The hydrogen sulfide content of the waste shall not exceed two mg/l at any time as shown by grab sample unless the POTW authorizes in writing an alternative mass limit for total sulfides.
E. 
Cyanide content. The cyanide content of the waste shall not exceed 10 mg/l total cyanide and two mg/l of cyanide readily released at 150° F. and pH 4.5. Cyanide content of wastewater must be measured by grab sample.
F. 
Fats, oils and greases. Wastewaters shall not contain in excess of 100 mg/l of fats, oils and greases of mineral or petroleum or unknown origin at any time as shown by grab sample. Wastewater discharged to the POTW shall contain no floatable or nonemulsified fats, oils and greases of animal or vegetable origin. Specific numerical limits for these pollutants may be placed in an industrial user's wastewater discharge permit if found by the POTW to be necessary. Wastewaters shall in no case contain concentrations of these pollutants high enough to cause interference or pass-through. The limits for both fats, oils and grease of mineral, petroleum or unknown origin and of animal or vegetable origin may be reduced by the Department without amending this chapter where the existing limits cause adverse impacts to the collector system and/or POTW.
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 Township reserves the right to establish by regulation more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in this chapter.
A. 
Spill prevention plan.
(1) 
Each user shall provide protection from accidental discharge of prohibited materials or other substances which may interfere with the POTW by developing a spill prevention plan. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the appropriate control authority for review and shall be approved by the appropriate control authority before construction of the facility. The spill plan shall contain, at a minimum, the following:
(a) 
Description of discharge practices, including routine and nonroutine batch discharges.
(b) 
Description of stored chemicals and MSDS on file.
(c) 
Procedures for promptly notifying the appropriate control authority of spills or slug discharges, with procedures for follow-up written notification within five working days.
