No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of a POTW. These general prohibitions apply to all such users of a POTW, whether or not the user is subject to national categorical pretreatment standards or any other national, state or local pretreatment standards or requirements.
A. 
A user may not 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 be injurious in any other way to a POTW or to the operation of a POTW. At no time shall two successive readings on an explosion hazard meter at the point of discharge into the system or at any point in the system be more than 5% nor any single reading over 10% of the lower explosive limit (LEL) of the meter. 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 substance which is a fire hazard or a hazard to a system.
(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.
(3) 
Any wastewater having a pH less than 6.0 or greater than 9.0 unless the POTW to receive said wastewater is specifically designed to accommodate such wastewater, or wastewater having any other corrosive property of causing damage or hazard to structure, equipment and/or personnel of said POTW.
(4) 
Any wastewater containing toxic pollutants which, either singly or by interaction with other pollutants, are in sufficient quantity to injure or interfere with any wastewater treatment process, constitute a hazard to humans and animals, create a toxic effect in the receiving waters or the POTW or exceed the limitations set forth in a federal categorical pretreatment standard. A toxic pollutant shall include but not be limited to any pollutant identified pursuant to Section 307(a) of the Act.
(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 are sufficient to prevent entry into the sewers for maintenance or repair.
(6) 
Any substance which may cause a POTW's effluent or any other product of a POTW, such as residues, sludges or scums, to be unsuitable for reclamation or reuse or to interfere with the reclamation process. In no case shall a substance discharged to a POTW cause a POTW to be in noncompliance with sludge use or disposal criteria, guidelines or regulations developed under Section 405 of the Act; or any criteria, guidelines or regulations affecting sludge use or disposal developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act or state criteria applicable to the sludge management method being used.
(7) 
Any substance which will pass through and as a result cause a POTW to violate its NPDES 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 a POTW treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the POTW which exceeds 40º C. (104º F.), unless the POTW treatment plant in question is designed to accommodate such temperature.
(10) 
Any pollutants, including oxygen demanding pollutants (BOD, etc.), released at a flow rate and/or pollutant concentration which cause interference to a POTW. In no case shall a waste load have a flow rate or contain concentrations or qualities of pollutants that exceed for any time period longer than 15 minutes more than five times the average twenty-four-hour concentration, quantities or flow during normal operation, unless otherwise authorized, in writing, by the Control Authority/Operator.
(11) 
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the control authority/operators in compliance with applicable state or federal regulations.
(12) 
Any wastewater which causes a hazard to human life or creates a public nuisance.
B. 
Grease, oil or sand interceptors shall be provided when, in the opinion of the control authority/operator, they are necessary for the proper handling of liquid wastes containing floatable grease in such amounts as to cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities or any flammable wastes, sand or other harmful ingredients, except such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the control authority/operator and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these interceptors, the owner(s) shall be responsible for the proper removal and disposal by appropriate means of the captured material and shall maintain records of the dates and means of disposal which are subject to review by the control authority/operator. Any removal and hauling of the collected materials not performed by owner's (owners') personnel must be performed by currently licensed waste disposal firms.
C. 
No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff, subsurface drainage, cooling water, unpolluted industrial or nonresidential process water. The discharge of cooling water from air-conditioning units with cooling towers or recirculating systems or from air-conditioning units using flow-through or unrecirculating systems is prohibited. The sanitary sewers are not designed to handle the cooling water volumes produced by air-conditioning units. Cooling water free from bacteria and harmful chemicals should be drained into storm sewers.
A. 
Standards. Upon promulgation of the federal categorical pretreatment standard under Section 307 of the Clean Water Act for a particular industrial subcategory, the pretreatment standard, if more stringent than limitations imposed by a control authority/operator's rates, rules and regulations for sources in that subcategory, shall supersede the limitations imposed by the control authority/operator in question. The control authority/operator shall notify all affected significant users of the applicable reporting requirements under 40 CFR 403.12.
B. 
Modification of standards. Where one of the wastewater treatment systems receiving wastewater flow from users in the Township achieves consistent removal of pollutants limited by federal categorical pretreatment standards, such system may apply to the approval authority for modifications of specific limits in the federal categorical pretreatment standards. "Consistent removal" shall mean the reduction in the amount of a pollutant or alteration of the nature of the pollutant by the wastewater treatment system to a less toxic or harmless state in the effluent which is achieved by the system in 95% of the samples taken when measured according to the procedures set forth in 40 CFR 403.7(c)(2). Such system may then modify pollutant discharge limits in the federal categorical pretreatment standards if the requirements contained in 40 CFR 403.7 are fulfilled and prior approval from the approval authority is obtained.
A. 
Specific pollutant limitations. The control authority/operator of each POTW servicing the Township shall have the right to impose specific pollutant limitations in its rates, rules and regulations.
B. 
State requirements. State requirements and limitations on discharges apply in any case where they are more stringent than federal requirements and limitations or those in this chapter or the control authority/operator's rates, rules and regulations.
C. 
Right of revision. The control authority/operator of each POTW serving the Township shall have the right to establish in its rates, rules and regulations more stringent limitations or requirements on discharge to the wastewater treatment system if deemed necessary and appropriate to comply with the objectives presented in §§ 205-1 through 205-4 of this chapter.
A. 
Excessive discharge. No user or significant user shall ever increase the use of process water or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the federal categorical pretreatment standards or in any other pollutant-specific limitation developed by the state or the control authority/operator of any POTW serving the Township.
B. 
Accidental discharge. Each user or significant user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner or user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to each control authority/operator for review and shall be approved by such control authority/operator before construction of the facility. All existing users and significant users shall complete such a plan when designated by each control authority/operator. No user or significant user who commences contribution to a POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until the accidental discharge procedures have been approved by the control authority/operator. Review and approval of such plans and operating procedures shall not relieve the user or significant user from the responsibility to modify its facility, as necessary, to meet the requirements of this chapter. In the case of an accidental discharge, it is the responsibility of the user or significant user to immediately telephone and notify the POTW of the incident. The notification shall include the location of the discharge, the type of waste, the concentration and volume and corrective actions.
C. 
Written report. Within five days following an accidental discharge, the user or significant user shall submit to the control authority/operator of the POTW in question a detailed written report describing the cause of the discharge and the measures to be taken by the user or significant user to mitigate and prevent any expense, loss, damage or other liability which may be incurred as a result of damage to the POTW or aquatic life or any other damages to person or property. Such report shall not relieve the user or significant user of any fines, civil penalties or other liability which may be imposed by this chapter or other applicable law. This written report shall be signed by an authorized representative of the user or significant user.
D. 
Notice to employees. A notice shall be permanently posted on the user's or significant user's bulletin board or other prominent place advising employees whom to call in the event of a dangerous discharge. Employers shall ensure that all employees who may cause such a dangerous discharge to occur are advised of the emergency notification procedures.
