§ 323-6 Use of publicly owned treatment works facilities.

The owner of any improved property benefited, improved or accommodated by a sewer shall connect such improved property with such sewer, in such manner as the Borough may require, within 45 days after becoming aware of such sewer or within 45 days after notice to such owner from the Borough to make such connection, for the purpose of discharge of all wastewater from such improved property; subject, however, to such limitations and restrictions as shall be established herein or otherwise shall be established by the Borough from time to time.

All wastewater from any improved property, after connection of such improved property to a sewer, shall be required under Subsection A to be conveyed into a sewer subject to the requirements set forth in this chapter.

No person shall place, shall deposit or shall permit to be placed or to be deposited upon public or private property within the Borough any wastewater in violation of this chapter. No person shall discharge or shall permit to be discharged, any wastewater in violation of this chapter.

No privy vault, cesspool, sinkhole, septic tank or similar receptacle shall be used or shall be maintained at any time upon any improved property that has been connected to a sewer or that shall be required under Subsection A to be connected to a sewer.

Every such privy vault, cesspool, sinkhole, septic tank or similar receptacle in existence shall be abandoned and, at the discretion of the Borough, shall be cleansed and shall be filled, at the expense of the owner of such improved property, under the direction and supervision of the Borough; and any such privy vault, cesspool, sinkhole, septic tank or similar receptacle not so abandoned and, if required by the Borough, not cleansed and filled, shall constitute a nuisance, and such nuisance may be abated, as provided by law, at the expense of the owner of such improved property.

No privy vault, cesspool, sinkhole, septic tank or similar receptacle at any time shall be connected with a sewer.

The notice by the Borough to make a connection to a sewer, referred to in Subsection A, shall consist of a copy of this chapter, including any amendments and/or supplements at the time in effect, or a summary of each section thereof, and a written or printed document requiring the connection in accordance with the provisions of this chapter and specifying that such connection shall be made within 45 days from the date such notice is given. Such notice may be given at any time after a sewer is in place that can receive and can convey wastewater for treatment and disposal from the particular improved property.

In addition to the requirements of § 323-17 of this chapter, oil/water separators shall be provided by users when they are necessary for the proper handling of liquid wastes containing floatable oil or grease in such amounts that may, in the opinion of the Superintendent, cause obstruction to the flow in a sewer or pass-through or interference with the operation of the POTW.

All oil/water separators shall be of a type and capacity approved by the Superintendent and the Borough and shall be located as to be readily and easily accessible for cleaning and inspection. In the maintaining of these oil/water separators, 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 Superintendent and the Borough. Any removal and hauling of the collected materials not performed by owner's (owners') personnel must be performed by currently licensed waste disposal firms.

§ 323-7 Building sewers and connections.

No unauthorized persons shall uncover, make any connections with or opening into, use, alter, or disturb the POTW or any appurtenance thereof without first obtaining written approval from the Borough as set forth in §§ 323-21 and 323-22 of this chapter.

All costs and expenses incidental to the installation, connection, and maintenance of the building sewer shall be borne by the owner(s). The owner(s) shall indemnify the Borough from any loss or damage that may directly or indirectly be occasioned by the installation of the building sewer.

A separate and independent building sewer shall be provided for every building.

Existing building sewers may be used in connection with new buildings only when they are found, on examination and test by the Superintendent, to meet all requirements of this chapter.

The size, slope, alignment, materials or construction of a building sewer and the methods to be used in excavating, placing of the pipe, joint testing, and backfilling the trench shall all conform to the requirements of the building and plumbing code or other applicable rules and regulations of the Borough. In the absence of building and plumbing code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the ASTM and WEF Manual of Practice No. 9 shall apply.

The building sewer shall be brought to the building at an elevation above the basement floor. In all buildings in which any building sewer is too low to permit gravity flow to the POTW, wastewater shall be lifted by a means approved by the Borough at the building owner's expense, in order to permit flow to the POTW.

No person shall make connection of sump pumps, roof downspouts, foundation drains, areaway drains, or other sources of surface runoff or groundwater to a building sewer which in turn is connected directly or indirectly to the POTW, unless such connection is approved in writing by the Superintendent.

The connection of the building sewer into the sewer shall conform to the requirements of the building and plumbing code. All such connections shall be made gastight and watertight, and verified by proper testing. Any deviation from the prescribed procedures and materials must be approved by the Superintendent before installation.

The applicant for the permit or the owner shall notify the Superintendent when the building sewer is ready for inspection and connection to the sewer. The connection to the sewer and testing shall be made under the supervision of the Superintendent or his representative.

All excavations for building sewer installation shall be adequately guarded with barricades and lights, so as to protect the public from hazards. Streets, sidewalks, parkways, and other public property disturbed in the course of the work shall be restored in a manner satisfactory to the Borough.

No excavation, construction, or connection work shall be commenced within a Borough right-of-way until the owner, lessees of a property, occupiers of a property, of any other party having a beneficial use or interest in the premises and occupying the same with the consent and permission of the owner of the fee title, or an agent or independent contractor of any of the aforementioned parties, shall have first obtained any necessary permits, including road opening/highway occupancy permits and occupancy permits, and filed a bond or established an escrow, as determined by the Borough, in an amount as determined by the Borough, and agreeing to indemnify and save harmless the Borough against any and all loss, damages, costs, and expenses that the Borough may thereafter suffer, incur, be put to or pay by reason of the failure to complete properly any of the aforesaid excavation, construction, or connection work.

§ 323-8 Federal categorical pretreatment standards.

The categorical pretreatment standards found at 40 CFR 405 through 471 are hereby incorporated in this chapter by reference as though set forth in full.

Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Superintendent may impose equivalent concentration or mass limits in accordance with 40 CFR 403.6(c).

When wastewater subject to a categorical pretreatment standard is mixed with wastewater not regulated by the same standard, the Superintendent may impose an alternate limit using the combined wastestream formula in 40 CFR 403.6(e).

A user subject to categorical pretreatment standards may obtain a variance 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 its discharge are fundamentally different from the factors considered by EPA when developing the categorical pretreatment standard.

A user may obtain a net gross adjustment to a categorical standard in accordance with 40 CFR 403.15.

§ 323-9 Modification of federal categorical pretreatment standards.

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 modifications of specific limits in the federal 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). The Borough may then modify pollutant discharge limits from the federal pretreatment standards if the requirements contained in 40 CFR 403.7 are fulfilled and prior approval from the approval authority is obtained.

§ 323-10 Specific local pollutant limitations.

[Amended 9-15-2010 by Ord. No. 1796; 12-21-2011 by Ord. No. 1816]

The following pollutant limits are established to protect against pass-through, noncompliance with the Borough's NPDES permit limitations, interference with and inhibition of treatment, interference with sludge disposal and/or adverse effects on utilization and worker safety. No person shall discharge or cause to be discharged wastewater containing in excess of the limitation set forth in the Specific Local Pollutant Limitations Table hereinbelow.

	NOTES:
	Note 1: Any user which discharges wastewater to the Borough's sewer system having concentrations of five-day biochemical oxygen demand (BOD₅), total suspended solids (TSS), ammonia-nitrogen (NH₃-N) and total phosphorus (TP) in excess the following concentrations will be subject to the Borough's strength surcharge program set forth in § 323-19:
	•	BOD₅: 230 mg/l
	•	TSS: 200 mg/l
	•	NH₃-N: 25 mg/l
	•	TP: 10 mg/l
	Note 2: "Total toxic organics (TTO)" is defined as the sum of all concentrations greater than the detection limit of the volatile organics, acid-extractable and base/neutral-extractable compounds of the 126 priority pollutants. No user may discharge any single toxic organic pollutant or combination of toxic organic pollutants in amounts which cause or contribute to pass-through or interference at the WWTP or in violation of any other portion of this chapter.

Concentrations apply at the point where the wastewater is discharged to the sewer. For users subject to categorical standards, categorical concentrations apply at the end of the process waste stream. The local limits listed above shall apply to any user's wastewater discharge which is not composed of strictly domestic sewage. All concentrations for metallic substances are for "total" metal, unless indicated otherwise. At its discretion, the Borough may establish alternate local limits in individual wastewater contribution permits, but only in accordance with regulatory requirements. At no time will the summation of the users' discharges for a specific pollutant be greater than the allowable wastewater treatment facility headworks loading as determined in the Borough's most-recent local limits evaluation. The local limits, if more stringent than the National Categorical Standards, shall supersede the National Categorical Standards.

The instantaneous maximum concentration of oil and grease shall not exceed 100 mg/l. In addition, no user may discharge total dissolved solids (TDS) in amounts which cause or contribute to pass-through or interference at the WWTP or in violation of any other portion of this chapter.

§ 323-11 State requirements.

State requirements and limitations on discharges shall apply in any case where they are more stringent than either federal requirements and limitations or those in this chapter.

§ 323-12 Borough's right of revision.

The Borough reserves the right to establish by ordinance, resolution of Borough Council or in permits more stringent limitations or requirements on discharges to the POTW if deemed necessary to comply with the objectives presented in § 323-2 of this chapter or the general and specific prohibitions in § 323-5 of this chapter.

§ 323-13 Dilution.

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 with any other pollutant-specific limitation developed by the Borough, state, or federal agencies, including local limits. The Borough may impose mass limitations on users who it believes are using dilution to meet applicable pretreatment standards or requirements, or in any other case in which the imposition of mass limitations is appropriate in the opinion of the Superintendent.

§ 323-14 Accidental discharge.

Each user designated by the Borough shall provide protection from accidental or slug discharges of prohibited materials or other substances that have the potential to cause interference or pass-through at the POTW and are regulated by this chapter. All users must notify the Borough of any changes at their facilities that may affect the potential for a slug discharge.

Facilities to prevent accidental discharges or slug discharges of prohibited materials shall be provided and maintained at the user's own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Borough and shall be approved by the Borough before construction of the facilities. All existing users shall complete such a plan within 90 days of notification to do so by the Borough or within 90 days of permit issuance.

No user who commences contribution to the POTW after the effective date of this chapter shall be permitted to introduce pollutants into the system until the accidental discharge and slug discharge procedures have been approved by the Borough. Review and approval of such plans and operating procedures shall not relieve the user from the responsibility to modify its facility, as necessary, to meet the requirements of this chapter.

In the case of an accidental discharge or slug discharge, or in the event a user becomes aware of a situation that could reasonably be expected to cause such an accidental discharge or slug discharge, it is the responsibility of the user to immediately notify the Superintendent by telephone of the incident. The notification shall include location of discharge, type of waste, concentration, volume and corrective actions taken.

Users shall notify the POTW, the EPA Regional Waste Management Division Director, and state hazardous waste authorities in writing of any accidental discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR 261, the EPA hazardous waste number, and an identification of the hazardous constituents contained in the wastes.

§ 323-15 Written report.

Within five days following an accidental discharge or slug discharge, the user shall submit to the Superintendent a detailed written report describing the cause of the discharge and the measures to be taken to prevent similar future occurrences, to mitigate 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 damage to person or property. Such report shall not relieve the user of any expense, loss, costs, or other liability which may be incurred as a result of damage to the POTW or any other damage to person or property nor shall such report relieve the user of any fines, civil penalties, or other liability which may be imposed by the chapter or other applicable law.

Written reports will be deemed to have been submitted on the date postmarked. For reports which are not mailed, postage prepaid, into a mail facility serviced by the United States Postal Service, the date of actual receipt of the report by the Borough shall govern.

§ 323-16 Notice to employees.

Users shall permanently post a notice in a prominent place or places sufficient to advise employees whom to call in the event of an unlawful discharge to sewers that could adversely affect the environment, the POTW or its operations, workers or the public. Employers shall ensure that all employees who may be in a position to discover or who, because of their job duties, could be in a position to inadvertently cause such a discharge, are advised of the emergency notification procedures.

§ 323-17 Fats, oil and grease (FOG) control.

The requirements of this § 323-17 shall apply to new or modified food service establishments, to any existing food service establishment upon the sale/transfer thereof, and to any existing food service establishments or other user determined by the Borough to be discharging FOG in sufficient quantities to require control.

Grease interceptor requirements: users shall install, operate, and maintain an approved type and adequately sized grease interceptor necessary to maintain compliance with the requirements of this § 323-17. In addition, all grease interceptors must meet the minimum requirements of the Uniform Construction Code as adopted by the Borough.

Implementation. All facilities required to install a grease interceptor must obtain prior approval from the Borough with respect to grease interceptor design, sizing, etc. prior to installation. In the case of newly constructed facilities, or existing facilities with planned modifications or plumbing improvements, approval from the Borough shall be obtained prior to receipt of building permits from the Borough. In the case of newly sold food service establishments, approval from the Borough shall be obtained prior to any discharge by the new owner. In the case of an existing food service establishment or other users determined by the Borough to require control, the users shall submit grease interceptor design and specifications for approval from the Borough within 45 days of notice by the Borough that such control is necessary, or as otherwise stated in the notice.

Definitions relative to food service establishments.

Existing food service establishments shall mean any food service establishment existing on the date of the enactment of this chapter.

New food service establishments shall mean any food service establishment which begins operation after the date of the enactment of this chapter.

Sale of a food service establishment shall mean the sale or transfer of operational control thereof.

Modified food service establishment shall mean an existing food service establishment undergoing material renovations, including without limitation renovations of the plumbing system or the addition of any equipment that may result in that change to the nature of the discharge to the POTW.

Variances from grease interceptor requirements. Grease interceptors required under this chapter shall be installed unless the Borough determines, in writing, that the installation of an indoor grease trap or other alternative pretreatment technology may be installed in lieu of a grease interceptor because the installation of a grease interceptor would not be reasonably feasible. The user bears the burden of demonstrating that the installation of a grease interceptor is not reasonably feasible. Conditions under which the installation of a grease interceptor would not be reasonably feasible may include instances in which the installation of a grease interceptor is not reasonably feasible due to space constraints. If an applicable user believes the installation of a grease interceptor is not reasonably feasible, it shall submit a written request for a determination by the Borough containing the following information:

Location of sewer main and easement in relation to available exterior space outside building;

A description of and plans showing existing plumbing at the facility, including plans showing any common plumbing for all wastewater services at the facility;

An explanation as to why the installation of a grease interceptor is not reasonably feasible;

A description of a design plan for any alternative pretreatment technology (other than a grease interceptor) proposed to be installed to trap, separate and hold FOG from wastewater and prevent it from being discharged into the POTW. All alternative pretreatment technology must be appropriate; and

(5)

A plan for regular maintenance of the alternative pretreatment technology.

Wastewater discharge limitations. No user shall allow wastewater containing FOG discharged from any grease interceptor, grease trap or alternative pretreatment technology to exceed 100 milligrams per liter.

Grease interceptor design/operation.

Grease interceptor sizing and installation shall conform to the version of the Uniform Construction Code currently adopted by the Borough or other applicable plumbing code used or approved by the Borough.

Grease interceptors shall be constructed in accordance with the design approved by the Borough and shall have a minimum of two compartments with fittings designed for grease retention.

Grease interceptors shall be installed at a location where it shall be easily accessible for inspection, cleaning, and removal of intercepted grease. The grease interceptor may not be installed in any part of the building where food is handled. Location of the grease interceptor must be approved by the Borough.

All such grease interceptors shall be serviced and emptied of accumulated waste content as required in order to maintain minimum design capability. These devices should be inspected at least monthly, and a written record of these inspections should be maintained as set forth in Subsection F(8).

(5)

Grease interceptors shall provide for a minimum hydraulic retention time in accordance with the Uniform Construction Code or other applicable plumbing code as adopted by the Borough.[1]

[1]

Editor's Note: See Ch. 146, Building Construction, and Ch. 292, Plumbing, respectively.

(6)

Grease interceptors shall be kept free of inorganic solid materials such as grit, rocks, gravel, sand, eating utensils, cigarettes, shells, towels, rags, etc., which could settle into this pocket and thereby reduce the effective volume of the device.

(7)

During the first year after installation, grease interceptors shall be pumped out at least semiannually or when 75% of the system capacity is reached, whichever is more frequent. After the first year of use, grease interceptors must be pumped out at least annually or when no more than 75% of the system capacity is reached, whichever is more frequent. After two years of use, the pumping frequency may be reduced, upon written approval of the Borough, if adequate documentation can be shown that a reduced pumping frequency is sufficient to comply with the provisions of this § 323-17.

(8)

The user shall maintain a written record of inspection and maintenance of the grease interceptor and disposal of FOG from the grease interceptor for five years. All such records will be made available for on-site inspection by a representative of the Borough.

(9)

All inspection and maintenance of the grease interceptor and disposal of FOG from the grease interceptor shall be conducted by adequately trained personnel.

(10)

Toilet wastes shall not be connected to sewer lines connected to grease interceptor service.

(11)
