[Added by Ord. 2007-6, 7/5/2007, § 3]
[Ord. 10-95-408, 10/26/1995, § 202; as amended
by Ord. No. 2017-07, 12/7/2017]
1. Users must comply with the categorical pretreatment standards found at 40 CFR, Chapter
I, Subchapter N, Parts 405-471, which are hereby incorporated.
2. 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 40 CFR 403.6(c).
3. When the limits in a categorical pretreatment standard are expressed
only in terms of mass of pollutant per unit of production, 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. 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. When a categorical pretreatment standard is expressed only in terms
of pollutant concentrations, an industrial user may request that the
City of Allentown convert the limits to equivalent mass limits. The
determination to convert concentration limits to mass limits is within
the discretion of the Director of Public Works. The City may establish
equivalent mass limits only if the industrial user meets all the conditions
set forth in § 18-406A(1) through (5).
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 so significantly that equivalent mass limits are not appropriate
to control the discharge; and
(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 Director of Public Works whenever production rates are expected to vary by more than 20% from its baseline production rates determined in Subsection
A(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; and
(4)
Continue to employ the same or comparable water conservation methods and technologies as those implemented pursuant to Subsection
A(1) of this section so long as it discharges under an equivalent mass limit.
C. When developing equivalent mass limits, 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; and
(3)
May retain the same equivalent mass limit in subsequent wastewater discharge 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 §
18-409. The industrial user must also be in compliance with §
18-467 regarding the prohibition of bypass.
6. 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 Director of Public Works. [Note: When converting such limits to concentration limits, the Director of Public Works will use the concentration 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 §
18-409 of this Part (see 40 CFR 403.6(d).]
7. 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. 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 of flow figure shall
be used in calculating both the average and the maximum equivalent
limitation. [Note: See 40 CFR 403.6(c)(8).]
9. Any industrial user operating under a permit incorporating equivalent
mass or concentration limits calculated from a production-based standard
shall notify 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 Director of Public Works of such anticipated
change will be required to meet the mass of 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. 1-96, 5/16/1996, § 203]
(Reserved)
[Ord. 1-96, 5/16/1996, § 204; as amended by Ord.
No. 2017-07, 12/7/2017]
1. The Director of Public Works is authorized to establish local limits
pursuant to 40 CFR 403.5(c).
2. Limits for discharging pollutants which are of concern to the POTW
will be made using headworks-loading analyses which have been reviewed
and approved by the approval 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 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 wastewater discharge permits, to implement local limits and the requirement of §
18-405.
4. Revisions. The City reserves the right to establish, by ordinance,
or, in wastewater discharge permits, more stringent standards or requirements
on discharges to the POTW consistent with the purpose of this Part.
5. Adoption by Township. No person shall discharge pollutants into the
sewer 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. 1-96, 5/16/1996, § 205; as amended by Ord.
No. 2017-07, 12/7/2017]
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. 1-96, 5/16/1996, § 206]
This Township reserves the right to refuse permission to connect
to the sewer system, to compel discontinuance of use of the sewer
system, or to compel pretreatment of wastewater in order to prevent
discharges deemed harmful or to have a deleterious effect upon the
sewer system or any other part of the POTW.
[Ord. 1-96, 5/16/1996, § 207]
Nothing contained in this Article shall be construed as prohibiting
any special agreement or arrangement between this Township, the City
and any person whereby wastes of unusual strength or character may
be admitted into the sewer system and the POTW by this Township and
the City either before or after preliminary treatment. However, no
such special agreement or arrangement shall allow violation of federal
pretreatment requirements or any other applicable federal or state
requirements. Whenever the approval authority shall deem it necessary
for the protection and safe, economical and efficient management of
the POTW, the owner of an improved property shall provide at the owner's
expense such facilities for preliminary treatment and processing of
industrial waste as may be necessary to reduce BOD to 300 mg/l, suspended
solids to 360 mg/1 and total Kjeldahl nitrogen to 85 mg/1.
