[Ord. No. 2020-04, 10/1/2020]
All sewage and authorized industrial waste may be discharged
to the sewerage system except those which are deemed harmful to the
system or are specifically prohibited by this chapter.
[Ord. No. 2020-04, 10/1/2020]
No person shall discharge or cause to be discharged any stormwater,
surface water, groundwater, roof runoff, subsurface drainage, uncontaminated
cooling water or unpolluted industrial process waters to any sanitary
sewer. Where existing surface water, groundwater, subsurface water
or roof drains are connected to the sewerage system, they shall be
removed within 30 days of receipt of a notice from the Township to
remove such connection. In the event such connection is not removed,
the Township shall cause such connection to be removed at the owner's
expense.
[Ord. No. 2020-04, 10/1/2020]
1. Any building floor drains shall have gravity or pumped discharge
completely independent of the sewerage system, except where the entire
finished floor is at an elevation above the finished grade around
the exterior of the building.
2. In commercial or industrial buildings, floor drains intended to receive
sewage and located below the exterior finished grade may be connected
to a drainage system which is connected to the sewerage system, subject
to the written approval of the Plumbing Inspector. Such approval will
be contingent upon the owner or his representative demonstrating that
adequate protection has been provided against the introduction of
stormwater, spring water, groundwater, subsurface drainage or building
foundation drainage into the sewerage system.
[Ord. No. 2020-04, 10/1/2020]
1. Prohibited Discharge Standards.
A. Clear Water. No person shall discharge or cause to be discharged
any stormwater, surface water, spring water, groundwater, roof runoff,
subsurface drainage, building foundation drainage, cellar drainage,
significant quantities of condensate, deionized water, noncontact
cooling water and unpolluted water, drainage from roof leader connections
and overflow or drainage from cesspools into the POTW.
B. General Prohibitions. No user or other person shall introduce or
cause to be introduced into the POTW any pollutant 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.

in 40 CFR 261.21 or 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 5% or any single reading over 10% of the
lower explosive limit of the meter.
(5)
Wastewater having a pH less than 5.0 or more than 12.0, or otherwise
causing corrosive structural damage to the POTW or equipment.
(6)
Solid or viscous substances in amounts which, alone or in combination
with other substances, will cause obstruction of the flow in the POTW
resulting in interference.
(8)
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.
(9)
Wastewater having a temperature that 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° F. (40° C.). Wastewater
having a temperature higher than 150° F. shall not be introduced
into the sewerage system without the express written approval of the
Township.
(10)

D. Storage and Processing of Wastes. 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 sewerage system or the
POTW.
[Ord. No. 2020-04, 10/1/2020]
1. In General. Users must comply with the categorical pretreatment standards found at 40 CFR Chapter
1, Subchapter N, Parts 405 through 471, which are hereby incorporated.
2. Standard Expressed in Mass or Concentration, but not both. Where a categorical pretreatment standard is expressed only in terms of either the mass or the concentration of a pollutant in wastewater, the Township and the Director of Public Works may impose equivalent concentration or mass limits in accordance with Subsections
5 and
6.
3. Conversion of Limits. When the limits in a categorical pretreatment
standard are expressed only in terms of mass of pollutant per unit
of production, the Township and the Director of Public Works 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.
4. Mixed Wastewater Whose Components are Subject to Different Standards.
When wastewater subject to a categorical pretreatment standard is
mixed with wastewater not regulated by the same standard, the Township
and the Director of Public Works shall impose an alternate limit using
the combined waste stream formula in 40 CFR 403.6(e).
5. Request by Industrial User for Conversion. When a categorical pretreatment
standard is expressed only in terms of pollutant concentrations, an
industrial user may request that the Township and the Director of
Public Works convert the limits to equivalent mass limits. The determination
to convert concentration limits to mass limits is within the discretion
of the Township and the Director of Public Works. The Township and
the Director of Public Works may establish equivalent mass limits
only if the industrial user meets all the conditions set forth below:
A. To be eligible for equivalent mass limits, the industrial user must:
(1)
Employ, or demonstrate that it will employ, water conservation
methods and technologies that substantially reduce water use during
the term of its wastewater discharge permit.
(2)
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.
(3)
Provide sufficient information to establish the facility's actual
average daily flow rate for all waste streams, 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.
(4)
Not have daily flow rates, production levels, or pollutant levels
that vary significantly that equivalent mass limits are not appropriate
to control the discharge.
(5)
Have consistently complied with all applicable categorical pretreatment
standards during the period prior to the industrial user's request
for equivalent mass limits.
B. An industrial user subject to equivalent mass limits must:
(1)
Maintain and effectively operate control and treatment technologies
adequate to achieve compliance with the equivalent mass limits.
(2)
Continue to record the facility's flow rates through the use
of a continuous effluent flow monitoring device.
(3)
Continue to record the facility's production rates and notify the Township and the Director of Public Works whenever production rates are expected to vary by more than 20% from its baseline production rates determined in Subsection
5A(3) of this section. Upon notification of a revised production rate, the Director of Public Works will reassess the equivalent mass limit and revise the limit as necessary to reflect changed conditions at the facility.
(4)
Continue to employ the same or comparable water conservation
methods and technologies as those implemented pursuant to this section
so long as it discharges under an equivalent mass limit.
C. When developing equivalent mass limits, the Township and the Director
of Public Works:
(1)
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.
(2)
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.
(3)
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 §
18-507. The industrial user must also be in compliance with §
18-1403 regarding the prohibition of bypass.
6. Conversion of Concentration Limits. The Township and the Director
of Public Works may convert the mass limits of the categorical pretreatment
standards of 40 CFR Parts 414, 419, and 455 to concentration limits
for purposes of calculating limitations applicable to individual industrial
users. The conversion is at the discretion of the Township and the
Director of Public Works.
(Note: When converting such limits to concentration limits, the Township and the Director of Public Works will use the concentrations listed in the applicable subparts of 40 CFR Parts 414, 419, and 455 and document that dilution is not being substituted for treatment as prohibited by §
18-507 of this chapter [see 40 CFR 403.6(d)]. In addition, the Township and the Director of Public Works will document how the equivalent limits were derived for any changes from concentration to mass limits, or vice versa, and make this information publicly available [see 40 CFR 403.6(c)(7)].)
7. Compliance with Equivalent Limitations. Once included in its permit,
the industrial user must comply with the equivalent limitations developed
in this section in lieu of the promulgated categorical standards from
which the equivalent limitations were derived. [Note: See 40 CFR 403.6(c)(7).]
8. Varying Limits for Calculating Maximum Daily and Monthly Discharge
Limits. Many categorical pretreatment standards specify one limit
for calculating maximum daily discharge limitations and a second limit
for calculating maximum monthly average, or four-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. [Note: See 40 CFR 403.6(c)(8).]
9. Notification of Change in Level. Any industrial user operating under
a permit incorporating equivalent mass or concentration limits calculated
from a production-based standard shall notify the Township and the
Director of Public Works within two 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
Township and the Director of Public Works 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. [Note: See 40 CFR 403.6(c)(9).]
[Ord. No. 2020-04, 10/1/2020]
1. The Director of Public Works is authorized to establish local limits
pursuant to 40 CFR 403.5(c).
2. City Limits. Limits for discharging pollutants which are of concern to the POTW will be made by the City using headworks loading analyses which have been reviewed and approved by the Allentown Authority. Allocations for discharging such pollutants will be made to each significant industrial user. Limits may be in the form of monthly average concentration, daily maximum concentration, or instantaneous maximum concentration. Limits will be contained in the wastewater discharge permits issued under §
18-702 and will be applied at the point where the wastewater is discharged to the POTW unless otherwise specified in the permit issued. All concentrations for metallic substances are for "total" metal unless indicated otherwise. The Township and the Director of Public Works may impose mass limitations in addition to, or in place of, the concentration-based limitations above.
3. The Director of Public Works may develop best management practices (BMPs), by ordinance or in a wastewater discharge permit, to implement local limits and the requirements of §
18-1402.
4. Revisions. The City reserves the right to establish, by ordinance,
intermunicipal agreement, or in wastewater discharge permits, more
stringent standards or requirements on discharges to the POTW consistent
with the purpose of this chapter.
5. Adoption by Township. No person shall discharge pollutants into the
sewerage system which would exceed the limits, or violate the restrictions
established by the City or the Director of Public Works as described
in this section and other portions of this chapter.
[Ord. No. 2020-04, 10/1/2020]
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 Township or the Director of Public Works 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.
[Ord. No. 2020-04, 10/1/2020]
The Township reserves the right to refuse permission to connect
to the sewerage system, to compel discontinuance of use of the sewerage
system or to compel pretreatment of wastewater in order to prevent
discharges deemed harmful or to have a deleterious effect upon the
sewerage system or any other part of the POTW.
[Ord. No. 2020-04, 10/1/2020]
1. Pretreatment Facilities.
A. Required Facilities. Users shall provide wastewater treatment as
necessary to comply with this chapter and shall achieve compliance
with all categorical pretreatment standards, City limits, Township
limits, and the prohibitions set forth in § 17-504 within
the time limitations specified by EPA, the Commonwealth of Pennsylvania,
the Director of Public Works, or the Township, whichever is more stringent.
Any facilities necessary for compliance shall be provided, operated,
and maintained at the user's expense.
B. Plans, Specifications, Etc. Detailed plans describing a user's proposed
wastewater pretreatment facilities and operating procedures shall
be submitted to the Director of Public Works and the Township for
review and approval before such facilities are constructed. Review
and approval of plans are not an endorsement of the effectiveness
of any facilities set forth therein, and neither the City nor the
Township shall be held liable or responsible in any way for the performance
of said facilities. The review of such plans and operating procedures
shall in no way relieve the user from the responsibility of modifying
such facilities as necessary to produce a discharge acceptable to
the City and the Township under the provisions of this chapter.
2. Additional Pretreatment Measures.
A. In General. Whenever deemed necessary, the Township or the Director
of Public Works may require users to restrict their discharge during
peak flow periods, designate that certain wastewater be discharged
only into specific sewers, relocate and/or consolidate points of discharge,
separate sewage waste streams from industrial waste streams, and such
other conditions as may be necessary to protect the sewerage system
and the POTW and determine the user's compliance with the requirements
of this chapter.
B. Flow Equalization. The Township or the Director of Public Works may
require any person discharging into the POTW to install and maintain,
on his property and at his expense, a suitable storage and flow control
facility to ensure equalization of flow. A wastewater discharge permit
may be issued solely for flow equalization.
C. Grease, Oil, and Sand Interception. Grease, oil, and sand interceptors
shall be provided when, in the opinion of the Township or the Director
of Public Works, they are necessary for the proper handling of wastewater
containing excessive amounts of grease and oil, or sand, except that
such interceptors shall not be required for residential users. All
interception units shall be of type and capacity approved by the Township
and the Director of Public Works, and shall be so located as to be
easily accessible for cleaning and inspection. Such interceptors shall
be inspected, cleaned, and repaired regularly, as needed, by the user
at the user's expense.
D. Combustible Gas Detection Meters. Users with the potential to discharge
flammable substances may be required to install and maintain an approved
combustible gas detection meter.
3. Accidental Discharge/Slug Control Plans.
A. Requirement of Plan. The Director of Public Works and/or the Township
shall evaluate whether each significant industrial user needs an accidental
discharge/slug control plan. The Township or the Director of Public
Works may require any user to develop, submit for approval to both
the Township and the Director of Public Works, and implement such
a plan. Alternatively, the Township or the Director of Public Works
may develop such a plan for any user, which shall be implemented by
the user.
B. Content of Plan. An accidental discharge/slug 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 Director of Public Works and the Township of any accidental or slug discharge, as required by §
18-806.
(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, including solvents, and/or
measures and equipment for emergency response.
4. Hauled Wastewater.
A. Tank Trucks and Equipment. Any tank truck or any equipment used or
intended to be used for the removal, transportation and disposal of
sewage and industrial wastes shall conform to the following requirements:
(1)

(4)
The inlet opening, or opening to every container, shall be so
constructed that the material will not spill outside during filling,
transfer or transport.
(5)
The outlet connections shall be so constructed that no material
will leak out, run out to other than the point of discharge and shall
be of a design and type suitable for the material handled and capable
of controlling the flow or discharge without spillage, undue spray
or flooding immediate surroundings while in use.
(6)
No connection shall be made at any time between a tap or outlet
furnishing potable water on any premises and any container or equipment
holding material by any means other than an open connection.
B. Discharge to Sewerage System. No hauler, operator, or other person
cleaning cesspools, septic tanks, privies, or other equipment for
on-lot management and storage of sewage shall discharge or otherwise
dispose of any wastewater into the Township's sewerage system.
[Ord. No. 2020-04, 10/1/2020]
Whenever the sewage and/or industrial waste discharged into the sewerage system contains substances which exceed the limitations specified in this chapter, or contain substances which clog sewers, are hazardous to the public health, or hinder sewage treatment or disposal, such as nonsoluble, flammable, or hazardous substances, the sewage and/or industrial waste must have been passed through an approved grease, oil, sand, or other type of interceptor which will effectively prevent such substances from entering the sewerage system. The interceptor shall conform to the requirements of the applicable provisions of the Pennsylvania Uniform Construction Code, with amendments [Chapter
5, Part
1], and shall be maintained by the owner, at his expense, in continuously efficient operation.
[Ord. No. 2020-04, 10/1/2020]
The use of mechanical garbage grinders producing a finely divided mass, properly divided mass, properly flushed with an ample amount of water, shall be permitted under the condition that no such mechanical garbage grinder to serve premises used for commercial purposes shall be installed until a permit for such installation has been obtained from the Plumbing Inspector, upon written application therefor. For such permit, owner or owners thereof shall pay such fee as shall be required by the applicable provisions of the Pennsylvania Uniform Construction Code, with amendments [Chapter
5, Part
1].
[Ord. No. 2020-04, 10/1/2020]
1. When pretreatment or flow-equalizing facilities are provided, they
shall be maintained continuously in a satisfactory and effective operation
by the owner, at his expense, and shall be subject to periodic inspection
by the Township and the City.
2. Failure by the owner to properly maintain pretreatment or flow-equalizing
facilities shall be considered sufficient cause for disconnection
of the improved property from the sewerage system.
3. The owner shall be liable for any and all damages directly attributable
to the pretreatment or flow-equalizing facilities.
[Ord. No. 2020-04, 10/1/2020]
The City and the Township reserve the right to establish more
stringent limitations or requirements on discharges into the sewerage
system than the limitations or requirements in Federal Categorical
Pretreatment Standards and/or state regulations.
[Ord. No. 2020-04, 10/1/2020]
1. Residential, commercial, or industrial property may be connected
to the storm sewer, providing the waste to be discharged thereto conforms
to the following:
A. All discharge of waste to storm sewers shall be in compliance with
the laws or regulations of the Commonwealth of Pennsylvania or the
federal government, or any agency thereof having jurisdiction over
streams, rivers, waterways, or water resources.
B. No waste, other than unadulterated rain, roof, or surface drainage
water, shall be discharged into a storm sewer, and the Township may
regulate the rate of discharge of such waste into a storm sewer.
2. No person shall drain any wastewater, except stormwater or authorized
industrial waste, into any drainage ditch or basin which will ultimately,
by natural flow or otherwise, enter into the storm sewer, or into
a stream, river, or watercourse. No person shall drain any wastewater,
except stormwater, into any gutter, street, or pavement.
3. All present connections to the storm sewer which are in violation
of any provisions of this chapter shall be abated immediately, and
application to connect to the storm sewer under the provisions of
this chapter shall be submitted within 30 days after the passage of
this chapter.
[Ord. No. 2020-04, 10/1/2020]
Where a person or industrial user stores material which is classified
as a hazardous substance or which is required by federal regulations
to be controlled or which requires a preparedness, prevention, and
contingency plan to be prepared in compliance with the Pennsylvania
Department of Environmental Protection, the Township will require
as part of any industrial waste permit application complete documentation
of the safeguards employed to prevent the discharge of leakage of
the material to any sanitary sewer or storm sewer.
[Ord. No. 2020-04, 10/1/2020]
Where pretreatment facilities are provided, sludges, floatables,
and oils generated by such facilities must be contained and transported
in a manner as prescribed by the rules of regulatory agencies including,
but not limited to, the U.S. Department of Transportation, and handled,
processed, and disposed of according to all federal, state, and local
regulations.
