A. 
The discharge of excessive amounts of unpolluted water or waste to the public sanitary sewerage system is expressly prohibited. However, such discharges to combined sewers or storm sewers will be permitted wherever such sewers have adequate capacity. The Borough reserves the right to define the amount it deems excessive in each particular situation.
B. 
The discharge of any garbage to the public sanitary sewerage system is expressly prohibited unless the garbage has first been properly shredded by a garbage grinder or garbage disposal device.
C. 
No person or user shall contribute or cause to be contributed, directly or indirectly, any pollutants that will pass through the POTW or 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. A user may not discharge any sanitary sewage or industrial wastes which will contribute the following substances to the 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 any other substances, to create a fire or explosion hazard in the POTW, including, but not necessarily limited to, any waste streams with a closed-cup flashpoint of less than 140° F. or 60° C., using the test methods specified in 40 CFR 261.21. At no time shall two successive readings on an explosion hazard meter at the point of discharge into the public sewer 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. Restricted 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 the Borough, the DEP or the EPA deems to pose a fire or explosion hazard.
(2) 
Any solid or viscous substances which may cause obstruction to the flow in a sewer, cause mechanical action which will destroy the sewer structures or in the opinion of the Borough may cause other interference with the operation of the POTW, including but not limited to grease, wax, 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, construction materials or debris, 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 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 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 Section 307(a) of the Act.
(4) 
Any noxious or malodorous liquid, gas or solid which, either singly or by interaction with other wastes, is, in the opinion of the Borough, sufficient to create a public nuisance or hazard to life or is sufficient to prevent entry into the sewers for their maintenance and repair.
(5) 
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 where the POTW is pursuing a reuse and reclamation program. 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, 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 method being used.
(6) 
Any substance which will cause the POTW to violate its NPDES and/or state disposal system permit or the receiving water quality standards for the Allegheny River.
(7) 
Any wastewater containing dyes, paints, pigments, ink or other coloring agents which are not removed by the treatment process and which, in the opinion of the Borough, will result in a discoloration or other undesirable physical change in the appearance of the receiving stream.
(8) 
Any wastewater having a temperature in excess of 65° C. (150° F.) or which will inhibit biological activity in the POTW treatment plant resulting in interference, but in no case wastewater that causes the temperature of the wastewater at the point of introduction into the POTW treatment plant to exceed 40° C. (104° F.).
(9) 
Any pollutant, including oxygen-demanding pollutants (BOD, etc.) released in a discharge at a flow rate and/or pollutant concentration which will cause interference to the POTW. Where the Borough deems it advisable, it may require any person discharging industrial wastes to utilize flow equalization or restricted discharge rates to prevent potential slug loading problems, such as in the case of batch discharges.
(10) 
Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Borough in compliance with applicable state or federal regulations.
(11) 
Any liquids or wastes containing suspended solids of such quality and/or quantity that there is interference with the POTW operation or that become burdensome to the operation and maintenance of the wastewater treatment plant facilities.
(12) 
Any wastewater having a pH lower than 5.5 or higher than 9.5 or having any other corrosive property which may cause damage or hazard to structures, equipment or personnel of the POTW. Where the Borough deems it advisable, it may require any person discharging industrial wastes to install and maintain, at his own expense, in a manner approved by the Borough, a suitable device to continuously measure and record the pH of the wastes so discharged.
(13) 
Any wastewater containing petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass-through or wastewater containing more than 100 mg/l of fat, oil or grease (hexane extractable) of animal or vegetable origin.
(14) 
Any wastewater containing insoluble, nonflocculent substances having a specific gravity in excess of 2.65 or soluble substances in such concentration as to cause the specific gravity of the waste to be greater than 1.1.
(15) 
Any wastewater or pollutants which result in the presence of toxic gases, vapors or fumes within the POTW in a quantity that may cause acute or chronic worker health and safety problems.
(16) 
Any wastewater containing more than 10.0 parts per million of any of the following gases: hydrogen sulfide, sulfur dioxide, nitrous oxide or any of the halogens.
(17) 
Any trucked or hauled wastewater or pollutants, except at a discharge point(s) designated by the Borough.
D. 
When the Borough determines that a user is contributing any of the above-enumerated substances to the POTW in such amounts that will pass through or interfere with the operation of the POTW, the Borough shall advise the user of the impact of the contribution on the POTW; develop specific effluent limitation(s) for such user to correct the interference with the POTW; and/or initiate appropriate enforcement action against the user pursuant to the provisions of Article X of this chapter.
A.

B. 
The limits set forth above may be amended from time to time as deemed necessary by the Borough to protect the facilities and ensure the POTW's compliance with applicable NPDES permit conditions and water quality standards.
No statement contained in this chapter shall be construed as prohibiting any special agreement or arrangement between the Borough and any person or industrial user whereby an industrial waste of unusual strength or character may be discharged to the POTW by the user, provided the objectives of the general pretreatment regulations and the provisions of this chapter are fulfilled. Similar to any other requirements imposed under this chapter, the provisions of any such special agreement will be superseded by any more stringent requirements of any applicable federal categorical pretreatment standard.
Upon the promulgation of the federal categorical pretreatment standard for a particular industrial subcategory, the federal standard, if more stringent than limitations imposed by the Borough under this chapter for sources in that subcategory, shall immediately supersede the limitations imposed by the Borough under this chapter. The Borough shall notify all affected users of the applicable federal standards and the applicable reporting requirements under 40 CFR 403.12, such as the baseline monitoring report.
A. 
Where the Borough's wastewater treatment system achieves consistent removal of pollutants limited by federal pretreatment standards, the Borough may apply to the approval authority for modification of specific limits in the federal pretreatment standards. "Removal" shall mean a reduction in the amount of a pollutant or an alteration of the nature of a pollutant in the influent to the POTW to a less toxic or harmless state in the effluent.
B. 
Consistent removal shall mean the average of the lowest 50% of the removals measured according to the procedures set forth in Section 403.7(b)(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 Borough may modify pollutant discharge limits in the federal pretreatment standards if the requirements contained in 40 CFR 403.7 are fulfilled and prior approval from the approval authority is obtained.
State requirements and limitations on discharges shall apply in any case where they are more stringent than federal requirements and limitations or those imposed by the Borough under this chapter.
The Borough reserves the right to establish by supplemental ordinances more stringent limitations or requirements on discharges to the POTW if deemed necessary.
No user shall ever increase the use of process water or cooling 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 specific pollutant limitation developed by the Borough or state. The Borough may impose mass limitations on industrial users who are using dilution to meet federal categorical pretreatment standards or any other specific pollutant limitation developed by the Borough or state or when the imposition of mass limitations are appropriate.
A. 
The Borough shall evaluate whether each SIU needs an accidental discharge/slug discharge control plan or other action to control slug discharges. The Borough may require any industrial user to develop, submit for approval, and implement such a plan or take such other action that may be necessary to control slug discharges. 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 chapter. Alternatively, the Borough may develop such a plan for any industrial user. An accidental discharge/slug discharge control plan shall address, at a minimum, the following:
(1) 
Description of discharge practices, including nonroutine batch discharges;
(2) 
Description of stored chemicals;
(3) 
Procedures for immediately notifying the Superintendent of any accidental or slug discharge, as required by § 157-16 of this chapter; and
(4) 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants.
B. 
Notification.
(1) 
All industrial users, whether permitted or not, shall immediately telephone and notify the Borough of all accidental spills, slug discharges or other discharges that could cause potential problems for the POTW. This notification shall include the location of the discharge, type of waste, concentration and volume of waste and any mitigating and/or corrective actions taken.
(2) 
Upon request by the Borough, the industrial user shall also prepare and submit to the Borough within five days after such notice a detailed written report describing the cause of the discharge and the measures to be taken by the user to prevent any similar occurrences in the future.
(3) 
Such notification shall not relieve the user of any expense, loss, damage, nor 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 chapter or other applicable law.
C. 
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 ensure that all employees who may cause or suffer such a dangerous discharge to occur are advised of the emergency notification procedure.
