A. 
General Prohibitions. No user shall introduce or cause to be introduced into the POTW any pollutants or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other national, state or local pretreatment standards or requirements.
B. 
Specific Prohibitions. No person shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:
(1) 
Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, waste streams with a closed-cup flashpoint of less than 140 degrees F (60 degrees C) using the test methods specified in 40 CFR 261.21;
(2) 
Wastewater having a pH less than 6.0 or more than 9.0, or otherwise causing corrosive structural damage to the POTW or equipment;
(3) 
Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference, but in no case solids greater than one-half 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, waste paper, wood, petroleum products (including plastics, gasoline, tar, asphalt residues, residues from refining or processing of fuel or lubricating oil), mud, glass grinding, or polishing wastes;
(4) 
Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW;
(5) 
Wastewater having a temperature greater than 120 degrees F (49 degrees C), or which will inhibit biological activity in the treatment plant resulting in interference, but in no case wastewater which causes the temperature at the introduction into the treatment plant to exceed 104 degrees F (40 degrees C);
(6) 
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
(7) 
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
(8) 
Trucked or hauled pollutants, except at discharge points designated by the Superintendent in accordance with Section 3.4 of this Ordinance;
(9) 
Noxious or malodorous liquids (including automobile antifreeze), gases, solids, or other wastewater which, either singly or by interaction with other wastes, are sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
(10) 
Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent, thereby violating the POTW's NPDES permit;
(11) 
Wastewater containing any radioactive wastes or isotopes except in compliance with applicable state or federal regulations and the requirements of the Joint Sewer Authority;
(12) 
Stormwater, surface water, groundwater, artesian well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized by the Joint Sewer Authority;
(13) 
Sludges, screenings, or other residues from the pretreatment of industrial wastes;
(14) 
Medical wastes, except as specifically authorized by the POTW in a wastewater discharge permit;
(15) 
Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail a toxicity test or causing noncompliance with sludge disposal requirements;
(16) 
Detergents, surface-active agents, or other substances which may cause excessive foaming in the POTW;
(17) 
Fats, oils, or greases of animal or vegetable origin in concentrations greater than 100 mg/l;
(18) 
Wastewater causing two readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, of more than five percent (5%) or any single reading over ten percent (10%);
(19) 
Any toxic or hazardous waste if otherwise disposed of would be considered hazardous or toxic waste. The discharge of toxic or hazardous wastes, as defined in the Act or in RCRA.
Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
The categorical pretreatment standards now found or hereafter found at 40 CFR Chapter I, Subchapter N, Parts 405 - 471, are hereby incorporated in this article by reference as though set forth in full and shall apply to users, including categorical industrial users, pursuant to the definitions set forth in this Ordinance and as set forth in the Ordinance.
A. 
Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Joint Sewer Authority may impose equivalent concentration or mass limits in accordance with Sections 2.2.E and 2.2.F.
B. 
When the limits in a categorical pretreatment standard are expressed only in terms of mass of pollutant per unit of production, the Superintendent may convert the limits to equivalent limitations expressed either as mass of pollutant discharged per day or effluent concentration for purposes of calculating effluent limitations applicable to individual industrial users.
C. 
When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same Standard, the Joint Sewer Authority shall impose an alternate limit using the combined waste stream formula in 40 CFR 403.6(e).
D. 
A user may obtain a net/gross adjustment to a categorical pretreatment standard in accordance with the following paragraphs of this section:
(1) 
Categorical pretreatment standards may be adjusted to reflect the presence of pollutants in the industrial user's intake water in accordance with this section. Any industrial user wishing to obtain credit for intake pollutants must make application to the Joint Sewer Authority. Upon request of the industrial user, the applicable standard will be calculated on a "net" basis (i.e., adjusted to reflect credit for pollutants in the intake water) if the requirements of paragraph (2) of this section are met.
(2) 
Criteria.
a. 
Either (i) the applicable categorical pretreatment standards contained in 40 CFR Subchapter N specifically provide that they shall be applied on a net basis; or (ii) the industrial user demonstrates that the control system it proposes or uses to meet applicable categorical pretreatment standards would, if properly installed and operated, meet the standards in the absence of pollutants in the intake waters.
b. 
Credit for generic pollutants such as biochemical oxygen demand (BOD), total suspended solids (TSS), and oil and grease should not be granted unless the industrial user demonstrates that the constituents of the general measure in the user's effluent are substantially similar to the constituents of the generic measure in the intake water or unless appropriate additional limits are placed on process water pollutants either at the outfall or elsewhere.
c. 
Credit shall be granted only to the extent necessary to meet the applicable categorical pretreatment standard(s), up to a maximum value equal to the influent value. Additional monitoring may be necessary to determine eligibility for credits and compliance with standard(s) adjusted under this section.
d. 
Credit shall be granted only if the user demonstrates that the intake water is drawn from the same body of water as that into which the POTW discharges. The Joint Sewer Authority may waive this requirement if it finds that no environmental degradation will result.
E. 
When a categorical pretreatment standard is expressed only in terms of pollutant concentrations, an industrial user may request that the Joint Sewer Authority convert the limits to equivalent mass limits with the exception of categorical concentration-based limits for pollutants such as pH, temperature, radiation, or any other pollutants for which mass limits are not appropriate. The determination to convert concentration limits to mass limits is within the discretion of the Joint Sewer Authority. The Joint Sewer Authority may establish equivalent mass limits only if the industrial user meets all the conditions set forth in Sections 2.2E(1)(a) through 2.2E(1)(e) below.
(1) 
To be eligible for equivalent mass limits, the industrial user must:
a. 
Employ, or demonstrate that it will employ, water conservation methods and technologies that substantially reduce water use during the term of its individual wastewater discharge permit;
b. 
Currently use control and treatment technologies adequate to achieve compliance with the applicable categorical pretreatment standard, and not have used dilution as a substitute for treatment;
c. 
Provide sufficient information to establish the facility's actual average daily flow rate for all wastestreams, based on data from a continuous effluent flow monitoring device, as well as the facility's long-term average production rate. Both the actual average daily flow rate and the long-term average production rate must be representative of current operating conditions;
d. 
Not have daily flow rates, production levels, or pollutant levels that vary so significantly that equivalent mass limits are not appropriate to control the discharge; and
e. 
Have consistently complied with all applicable categorical pretreatment standards during the period prior to the industrial user's request for equivalent mass limits.
(2) 
An industrial user subject to equivalent mass limits must:
a. 
Maintain and effectively operate control and treatment technologies adequate to achieve compliance with the equivalent mass limits.
b. 
Continue to record the facility's flow rates through the use of a continuous effluent flow monitoring device;
c. 
Continue to record the facility's production rates and notify the Joint Sewer Authority whenever production rates are expected to vary by more than 20 percent from its baseline production rates determined in Paragraph 2.2F(1)(c) of this section. Upon notification of a revised production rate, the Joint Sewer Authority will reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility; and
d. 
Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to paragraphs 2.2E(1)(a) of this section so long as it discharges under an equivalent mass limit.
(3) 
When developing equivalent mass limits, the Joint Sewer Authority:
a. 
Will calculate the equivalent mass limit by multiplying the actual average daily flow rate of the regulated process(es) of the industrial user by the concentration-based daily maximum and monthly average standard for the applicable categorical pretreatment standard and the appropriate unit conversion factor;
b. 
Upon notification of a revised production rate, will reassess the equivalent mass limit and recalculate the limit as necessary to reflect changed conditions at the facility; and
c. 
May retain the same equivalent mass limit in subsequent wastewater discharger permit terms if the industrial user's actual average daily flow rate was reduced solely as a result of the implementation of water conservation methods and technologies, and the actual average daily flow rates used in the original calculation of the equivalent mass limit were not based on the use of dilution as a substitute for treatment pursuant to Section 2.6. The industrial user must also be in compliance with Section 12.3 regarding the prohibition of bypass.
F. 
The Joint Sewer Authority may convert the mass limits of the categorical pretreatment standards of 40 CFR Parts 414, 419, and 455 to concentration limits of the categorical pretreatment standards for purposes of calculating limitations applicable to individual industrial users. The conversion is at the discretion of the Joint Sewer Authority. The Authority shall not convert such limits to concentration limits unless it first documents that dilution is not being substituted for treatment as prohibited by Section 2.6.
G. 
Once included in its permit, the industrial user must comply with the equivalent limitations developed in accordance with this section 2.2 in lieu of the promulgated categorical standards from which the equivalent limitations were derived.
H. 
Many categorical pretreatment standards specify one limit for calculating maximum daily discharge limitations and a second limit for calculating maximum monthly average, or 4-day average, limitations. Where such standards are being applied, the same production or flow figure shall be used in calculating both the average and the maximum equivalent limitation.
I. 
Any industrial user operating under a permit incorporating equivalent mass or concentration limits calculated from a production-based standard shall notify the Joint Sewer Authority within two (2) business days after the user has a reasonable basis to know that the production level will significantly change within the next calendar month. Any user not notifying the Joint Sewer Authority of such anticipated change will be required to meet the mass or concentration limits in its permit that were based on the original estimate of the long-term average production rate.
J. 
A user may obtain a variance from a categorical pretreatment standard from EPA if the user can prove, pursuant to the procedural and substantive provisions in 40 CFR 403.13, that factors relating to its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.
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 Ordinance.
A. 
The Joint Sewer Authority is authorized to establish local limits pursuant to 40 CFR 403.5(c). The following pollutant limits are established to protect against pass through and interference. No person shall discharge wastewater containing in excess of the following daily maximum limit:
Toxic Pollutants
mg/L
Arsenic
1.165
Cadmium
0.107
Chromium (total)
0.260
Copper
5.558
Cyanide
2.328
Lead
0.969
Mercury
0.008
Molybdenum
0.418
Nickel
2.046
Selenium
11.699
Silver
7.098
Zinc
2.800
BOD5
250
Suspended solids
250
Ammonia nitrogen
25
Total Kejldahl nitrogen
40
The above limits apply at the point where the wastewater is discharged to the POTW, which for purposes of this Ordinance includes all points within and throughout the distribution system. All concentrations for metallic substances are for "total" metal unless indicated otherwise. The Joint Sewer Authority may impose mass limitations in addition to, or in place of, the concentration-based limitations above.
B. 
The Joint Sewer Authority reserves the right to establish alternate local limits in industrial user discharge permits, but only in accordance with regulatory requirements. At no time will the summation of the loadings allocated to the industrial users discharges through the discharge permits be greater than the allowable industrial headworks loading as determined in the most recent local limits evaluation approved by the Approval Authority.
The Joint Sewer Authority and/or the Township may develop best management practices (BMPs), by ordinance or in wastewater discharge permits, to implement local limits and the requirements of Section 2.1. If a BMP is used in place of an approved local limit or prohibition (rather than in addition to an approved limit or prohibition), the BMP would need to be approved by EPA prior to implementation. Authorizing use of a BMP for compliance with one or more of the prohibitions included in 40 CFR 403.5 does not relieve the user of the responsibility of complying with the prohibition(s).
The Township reserves the right to establish, by ordinance, more stringent standards or requirements on discharges to the POTW.
No 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 a discharge limitation unless expressly authorized by an applicable pretreatment standard or requirement. The Joint Sewer Authority may impose mass limitations on users who are using dilution to meet applicable pretreatment standards or requirements, or in other cases when the imposition of mass limitations is appropriate.
Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this Ordinance. 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 Joint Sewer Authority for review, and shall be approved by the Joint Sewer Authority before construction of the facility. No user shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the Joint Sewer Authority. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements of this Ordinance. In the case of an accidental discharge, it is the responsibility of the user to immediately notify the Joint Sewer Authority of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.
Within twenty-four (24) hours following an accidental discharge, the user shall notify the Joint Sewer Authority, and within five (5) days following an accidental discharge, the user shall submit to the Joint Sewer Authority a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. Such notification shall not relieve the user of any expense, loss, damage, or other liability which may be incurred as a result of damage to the POTW, fish kills, or any other damage to person or property, nor shall such notification relieve the user of any fines, civil penalties, or other liability which may be imposed by this article or other applicable law.
A notice shall be permanently posted on the user's bulletin board or other prominent place advising employees whom to call in the event of an accidental discharge. Employers shall insure that all employees who may cause or suffer such an accidental discharge to occur are advised of the emergency notification procedures.
