[Amended 12-7-1992 by Ord. No. 202]
No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will pass through or interfere with the operation or performance of the 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 user may not contribute the following substances to the POTW:
A. 
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 the POTW or to the operation of the 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 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 the system. Also specifically prohibited is any resulting waste stream with a closed cup flash point of less than 140° F.
B. 
Any 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, wastepaper, wood, plastics, gas, tar, asphalt residues, residues from refining, or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes.
C. 
Any wastewater having a pH less than five, or wastewater having any other corrosive property capable of causing damage or hazard to structures, equipment, and/or personnel of the POTW.
D. 
Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the POTW, or to exceed the limitation set forth in a categorical pretreatment standard. 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, or solids which either singly or by interaction with other wastes are sufficient to create a public nuisance, or health and safety problem at the POTW or to the public at large, or are sufficient to prevent entry into the sewers for maintenance and repair.
F. 
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 § 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,[1] or state criteria applicable to the sludge management method being used, or POTW's own reasonably established standards.

Editor's Note: See 42 U.S.C. § 6901 et seq., 42 U.S.C. § 7401 et seq., and 15 U.S.C. § 2601 et seq., respectively.
G. 
Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving 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 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 treatment plant which exceeds 40° C. (104° F.).
J. 
Any pollutants, including oxygen demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the POTW. In no case shall a slug load have a flow rate or contain concentration 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.
K. 
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the General Manager in compliance with applicable state or federal regulations.
L. 
Any wastewater which causes a hazard to human life or creates a public nuisance.
M. 
Any trucked or hauled pollutants, except at discharge points designated by the POTW.
A. 
When the General Manager determines that a user(s) is contributing to the POTW any of the above enumerated substances in such amounts as to pass through or interfere with the operation of the POTW, the General Manager shall:
(1) 
Advise the user(s) of the impact of the contribution on the POTW; and
(2) 
Develop effluent limitation(s) for such user to correct the pass-through or interference with the POTW.
B. 
When the General Manager determines that a user(s) is contributing any of the above enumerated substances to the POTW but cannot determine the amount of relationship to a current pass-through or interference with the operation of the POTW, the General Manager may:
(1) 
Advise the user(s) of the possible impact of the contribution on the POTW; and
(2) 
Develop temporary effluent limitation(s) for such user to attempt correction of the pass-through or interference with the POTW.
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 2 for sources in that category, shall immediately supersede the limitations imposed under this Part 2.
Where the municipalities' wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the municipalities may apply to the approval authority for modification of specific limits in the federal pretreatment standards. "Consistent removal" shall mean 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 § 403.7(c)(2) of 40 CFR 403, General pretreatment regulations for existing and new sources of pollution, promulgated pursuant to the Act. The municipalities may then modify pollutant discharge limits in the federal pretreatment standards if the requirements contained in 40 CFR 403, § 403.7, are fulfilled and prior approval from the approval authority is obtained.
[Amended 12-7-1992 by Ord. No. 202]
A. 
No person shall discharge wastewater containing in excess of the stricter of either the then-existing local limits, the specific restriction of their wastewater permit, or other applicable state or federal limits, unless there is a valid and lawful wastewater permit in effect between the POTW and that person which specifies and permits a particular parameter despite a more restrictive limit for that element. The current local limits are attached to this chapter as Attachment A[1] and incorporated herein by reference as if fully set forth. Local limits may be revised at any time without prior notice by the POTW in its discretion in accordance with recommendations of any local limits technical evaluation the POTW receives. If local limits are revised, then to the extent otherwise permissible by law, a reasonable schedule for compliance with the new parameters will be granted to the permittee.
[1]
Editor's Note: See Attachment 2 to this chapter.
B. 
These limits shall be deemed pretreatment standards for purposes of § 307(d) of the Clean Water Act. Any wastewater permit specification and permission for a particular parameter despite a more restrictive local limit for that element shall in every case require for its validity express, written approval from the United States Environmental Protection Agency, and any and all permitting requirements of that or any other agency with jurisdiction must first be successfully completed.
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 Part 2.
The municipalities reserve the right to establish at any time by resolution more stringent limitations or requirements on discharges to the wastewater disposal system if deemed necessary to comply with the objectives presented in § 425-6 of this Part 2.
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 the limitations contained in the federal categorical pretreatment standards, or in any other pollutant-specific limitation developed by the municipalities or state.
[Amended 12-7-1992 by Ord. No. 202]
A. 
Each user shall provide protection from accidental discharge of prohibited materials or other substances regulated by this Part 2. Facilities to prevent accidental discharge or prohibited materials shall be provided and maintained at the owner's or user's own cost and expense. Detailed plans showing facilities and operation procedures to provide this protection shall be submitted to the POTW for review, and shall be approved by the POTW before construction of the facility. All existing users shall complete such a plan within 90 days of the date of this Part 2. No user who commences contribution to the POTW after the effective date of this Part 2 shall be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the POTW. 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 Part 2. In the case of an accidental discharge, it is the responsibility of the user to immediately telephone and notify the POTW of the incident. The notification shall include location of discharge, type of waste, concentration and volume, and corrective actions.
B. 
Written notice. Within five days following an accidental discharge or any hazardous waste discharge, the user shall submit to the General Manager a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent similar future occurrences. The user shall copy such written notification to EPA and to DEP. Such notification shall not relieve the user of any expense, loss, damage, or damage to the POTW, fish kills, or any other damage to person or property; nor shall such notification relieve the user of any civil penalties, or other liability which may be imposed by this Part 2 or other applicable law.
C. 
Notice to employees. 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 a dangerous discharge. Employers shall insure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
D. 
Periodic evaluation. At least once every two years, the POTW shall evaluate every SIU to determine whether each such SIU needs a plan to control slug discharges. Each SIU shall cooperate fully with such periodic evaluations.
