[Ord. 156, 4/26/1994, § 2.1; as amended by Ord. 264, 8/16/2011]
1. 
No user or significant industrial user may contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater that will cause a pass-through or interference in the Township's wastewater collection and/or PWTA treatment system, will create a hazard to the environment, the general public, PWTA or Township personnel, or will cause the PWTA to violate any general pretreatment regulation, NPDES permit or biosolids requirement. These general prohibitions apply to all such users of a wastewater collection and treatment system, whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state or local pretreatment standards or requirements.
2. 
A user or significant industrial user may not contribute the following substances to the wastewater collection and/or PWTA treatment system:
A. 
Any liquids, solids, or gases that, 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 wastewater collection and treatment system or will disrupt the operation of the wastewater collection and treatment system. 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). Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, hydrides, sulfides, aldehydes, peroxides, chlorates, perchlorates, bromates and carbates and any other substance that presents a fire hazard or other hazard to the sewer system, including any material or waste stream exhibiting a closed-cup flashpoint of less than 140° F. (i.e., waste streams whose vapors ignite or burn at temperatures below 140° F.).
B. 
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, 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, waste paper, wood, plastics, gas, tar, asphalt residues, mud glass grinding, polishing wastes, petroleum oil, and nonbiodegradable cutting oil or mineral oil products that will interfere or cause pass-through at the PWTA treatment plant.
C. 
Any wastewater having a pH less than 5.0, or greater than 9.0, standard units, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the wastewater collection and treatment system.
D. 
Any wastewater containing toxic pollutants in sufficient quantity, either alone or in conjunction with other pollutants, that will cause a pass-through or interference in the Township's wastewater collection and/or PWTA treatment system, will create a hazard to the environment, the general public, Township or PWTA personnel, or will cause the PWTA to violate any general pretreatment regulation, NPDES permit or biosolids requirement. These general prohibitions apply to all such users of a wastewater collection and treatment system, whether or not the user is subject to National Categorical Pretreatment Standards or any other national, state, or local pretreatment standards or requirements. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to § 307(a) of the Act.
E. 
Any noxious or malodorous liquids, gases, vapors, solids or fumes that, either alone or in conjunction with other wastes, are sufficient to create a public nuisance or hazard to life, cause health and safety problems or are sufficient to prevent entry into the sewers for maintenance and repair.
F. 
Any substance that may cause the wastewater treatment plant effluent or any other product of the wastewater collection and treatment system, such as residues, biosolids, or scums, to be unsuitable for reclamation and reuse or which will interfere with the reclamation process. In no case shall a substance discharged to the wastewater collection and treatment system cause the PWTA to be in noncompliance with its biosolids use or disposal criteria, guidelines, or regulations developed under § 405 of the Act or developed pursuant to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance Control Act or state criteria applicable to the biosolids management method being used.
G. 
Any substance what will cause the PWTA to violate its NPDES permit or the receiving stream water quality standards.
H. 
Any wastewater with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
I. 
Any wastewater having a temperature that will inhibit biological activity in the wastewater collection and treatment system treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the wastewater collection system that will result in a wastewater treatment plant influent flow exhibiting a temperature which exceeds 40° C. (104° F.).
J. 
Any pollutants, including oxygen-demanding pollutants (BOD, COD, etc.), released at a flow rate and/or pollutant concentrations that cause interference to the wastewater collection and treatment system. In no case shall wastewater be discharged at a flow rate or containing concentrations or quantities 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 of that particular industry.
K. 
Any wastewater containing any radioactive wastes or isotopes of such halflife or concentration as may exceed limits established by the PWTA Manager in compliance with applicable state or federal regulations.
L. 
Any wastewater that causes a hazard to human life or creates a public nuisance.
M. 
Stormwater, groundwater, roof runoff, subsurface drainage or cooling water.
N. 
Trucked or hauled wastes, except at a point of discharge indicated by the wastewater treatment plant Manager or his duly authorized agent.
O. 
Wastewater having an oil and grease concentration greater than 100 mg/l.
3. 
When the Township or the PWTA determines that a user or significant industrial user is contributing to the wastewater collection and treatment system any of the above-prohibited substances, the PWTA Manager may advise the user of the impact of such contributions on the wastewater collection and treatment system and develop effluent limitations and compliance schedules which the user must meet to correct the violation.
4. 
The PWTA or the Township may take enforcement action(s) against the noncomplying user or significant industrial user regardless of whether the user or significant industrial user was given prior notification of the violation by the PWTA.
[Ord. 156, 4/26/1994, § 2.2]
1. 
Upon the promulgation of the Federal Categorical Pretreatment Standards for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed under this Part for sources in that subcategory, shall immediately supersede the limitations imposed under this Part. Each user or significant industrial user shall be responsible to notify the Township and the PWTA of changes to his status under the federal, state or local regulations. The categorical pretreatment standards found in 40 CFR, Chapter 1, Subchapter N, Parts 405-471, are also hereby incorporated into this Part.
A. 
Where a categorical pretreatment standard is expressed only in terms of the mass or the concentration of a pollutant in wastewater, the PWTA Manager may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c).
B. 
When process wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the PWTA Manager shall impose an alternate limit using the combined waste stream formula in 40 CFR 403.6(e).
C. 
A user may obtain a variance from the EPA from a categorical pretreatment standard if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to his facilities discharge are fundamentally different from the factors considered by the EPA when developing the categorical pretreatment standard.
D. 
A user may obtain a net gross adjustment to a categorical pretreatment standard in accordance with 40 CFR 403.15.
[Ord. 156, 4/26/1994, § 2.3]
Where the PWTA wastewater treatment plant achieves consistent removal of pollutants limited by Federal Categorical Pretreatment Standards, the PWTA 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 collection 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 § 403.7(c)(2) of Title 40 of the Code of Federal Regulations, Part 403, General Pretreatment Regulations for Existing and New Sources of Pollution, promulgated pursuant to the Act. The PWTA may then modify the pollutant discharge limits in the federal pretreatment standards if the requirements contained in 40 CFR, Part 403, 403.7, are fulfilled and prior approval from the approval authority is obtained.
[Ord. 156, 4/26/1994, § 2.4; as amended by Res. 98-9, 4/28/1998; by Ord. 176, 4/28/1998, §§ 1, 2; and by Res. 2002-03, 2/19/2002]
All wastewater entering the sanitary sewerage system shall be pretreated to typical domestic levels unless otherwise stated in writing by the PWTA by way of the significant industrial user permit. Typical domestic levels and specific pollutant limitations may require periodical change because of changing NPDES requirements, required reevaluations of the local limits analysis or other reasons. At times when such change becomes necessary, modified local limits will be established and formally adopted by the PWTA after modifications have been approved by the approval authority (USEPA). Upon recommendation and approval by the PWTA, industrial pretreatment discharge limitations shall be established and revised by separate resolution of the Board of Supervisors and shall be attached as Appendix A to this section.[1]
[1]
Editor's Note: Appendix A is included as an attachment to this chapter.
[Ord. 156, 4/26/1994, § 2.5]
The PWTA reserves the right to request the Township to establish by ordinance, limitations or requirements at least as stringent as the PWTA for those users within its jurisdiction whose wastewater is ultimately treated by the PWTA in order to comply with the objectives of § 18-201.
[Ord. 156, 4/26/1994, § 2.6]
No user or significant industrial 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 with any other pollutant-specific limitation developed by the Township, the PWTA, or state or federal agencies.
[Ord. 156, 4/26/1994, § 2.7; as amended by Ord. 264, 8/16/2011]
1. 
Each user shall provide protection from slug discharge or prohibited materials or other substances regulated by this Part. To prevent the discharge of prohibited materials, facilities shall be provided and maintained at the user's or significant industrial user's own cost and expense. In the case of a slug discharge which has the potential to violate any of the specific provisions contained in 40 CFR 403.5, or to pass-through or interfere with treatment plant, it is the responsibility of the user to immediately telephone and notify the Township and PWTA Manager of the incident. The notification shall include location of discharge, type of waste, concentration, and volume and corrective actions taken to minimize and eliminate the violation.
2. 
Also, within five days following a slug discharge, the user shall submit to the Township and the PWTA a detailed written report that shall contain the following information:
A. 
The cause of the noncompliance.
B. 
The approximate time that this condition occurred and whether it has been corrected.
C. 
The steps taken by the user to reduce and minimize the impact of the noncompliance.
D. 
The steps taken by the user to prevent a reoccurrence of the conditions that caused or led to the accidental or slug loading.
3. 
Submission of such a report shall not relieve the user or significant industrial user of any fines, civil penalties, or other liability that may be imposed as described in this Subpart, the PWTA enforcement response plan or any other applicable law.
4. 
In addition, the PWTA will evaluate at least once per year whether a significant industrial user needs to develop or update a slug control plan. Detailed slug control plans showing facilities and operating procedures to provide slug control protection shall be submitted to the PWTA for review and approval prior to implementation. A slug control plan shall contain, at a minimum, the following information:
A. 
A description of discharge practices, including routine or nonroutine batch discharges.
B. 
A description of new and spent chemical storage procedures.
C. 
Procedures for immediately notifying the PWTA Manager of any accidental or slug discharge, including personnel responsible for such notifications.
D. 
Procedures to prevent adverse impact from an accidental or slug discharge. Such procedures shall include, but are not limited to, inspection and maintenance of chemical storage areas, handling and transferring of raw and finished products and chemicals, control of site runoff, worker training, building of containment structures, available containment equipment and contracted environmental services that assist the user to fulfill these plans.
5. 
A significant industrial user who commences contribution to the wastewater collection and treatment system after the effective date of this Part shall not be permitted to introduce pollutants into the system until a slug control plan has been approved by the PWTA. Review and approval of such plans and operating procedures shall not relieve the significant industrial user from the responsibility to modify his facility, as necessary, to meet the requirements of this Part.
6. 
All users are required to notify the PWTA immediately of any changes at their facilities affecting the potential for an accidental discharge and/or slug discharge to the PWTA.
[Ord. 156, 4/26/1994, § 2.8]
The PWTA Manager or Township reserves the right to require any user of the Township's sewer system to install permanent sampling equipment in order to determine compliance with this Part. The type of sampling equipment and installation location must be reviewed and approved by the PWTA Manager.
[Ord. 156, 4/26/1994, § 2.9]
A notice shall be permanently posted on the significant user's bulletin board or other prominent place advising employees whom to call in the event of an accidental or slug discharge. Employers shall ensure that all employees who may be involved with hazardous materials are aware of such emergency notification procedures.
