A.
No user shall contribute or cause to be contributed,
directly or indirectly, any pollutant or wastewater which will interfere
with the operation or performance of the POTW or which causes pass-through.
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 any POTW:
[Amended 6-30-2008 by Ord. No. 2008-10]
(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 other substances, to cause fire or explosion, including but not
limited to waste streams with a closed-cup flash point of less than
140° F. (60° C.) using the test methods specified in 40 CFR
261.21 or which are, or may 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 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 the Authority,
the state or the EPA has notified the user is a fire hazard or a hazard
to the system.
(2)
Solid or viscous 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, 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 having a pH less than 6.0 or greater
than 9.0 or wastewater having any other corrosive property capable
of causing damage or hazard to structures, equipment and/or personnel
of the POTW, unless as otherwise specified in a permit.
(4)
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.
(5)
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 hazard to life or are sufficient to
prevent entry into the sewer for maintenance and repair.
(6)
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. 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 or 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.
(7)
Any substance which will cause the POTW to violate
its NPDES and/or state disposal system permit or the receiving water
quality standards.
(8)
Any wastewater with objectionable color not removed
in the treatment process, such as but not limited to dye wastes and
vegetable tanning solutions.
(9)
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 which exceeds 40° C. (104° F.) or exceeds 65°
C. (150° F.) at the point of discharge to the sewer system.
(10)
Any pollutants, including oxygen demand 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. 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.
(11)
Any wastewater containing any radioactive wastes
or isotopes of such half-life or concentration in accordance with
applicable state or federal regulations.
(12)
Any wastewater which causes a hazard to human
life or creates a public nuisance.
(13)
Petroleum oil, nonbiodegradable cutting oil,
or products of mineral oil origin in amounts that will cause interference
or pass-through.
(14)
Pollutants which result in the presence of toxic
gases, vapors or fumes within the POTW in a quantity that may cause
acute worker health and safety problems.
(15)
Trucked or hauled pollutants, except at discharge
points designated by the Authority or the Township.
B.
When the Authority determines that a user is contributing
to its POTW any of the above-enumerated substances in such amounts
as to interfere with the operation of its POTW, the Authority shall:
A.
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 5 for sources
in that subcategory, shall immediately supersede the limitations imposed
under this Part 5. The Township or the Authority shall notify all
affected users of the applicable reporting requirements under 40 CFR
403.12.
A.
The Authority, in accordance with the United States
EPA regulations, shall develop and maintain technically based local
limits. Local limits shall be developed through the evaluation of
the following criteria:
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 5.
The Authority reserves the right to establish by ordinance more-stringent limitations or requirements on discharges to the wastewater disposal system, if deemed necessary, to comply with the objectives presented in § 155-30 of this Part 5 or as required by the United States Environmental Protection Agency.
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 Authority or the state.
A.
Accidental and/or problem discharges. Each user shall
provide protection from accidental discharge of prohibited materials
or other substances regulated by this Part 5 and from discharges that
could cause problems to the operations of the POTW, including any
slug loadings. Facilities to prevent accidental or problem discharge
of prohibited materials shall be provided and maintained at the owner's
or user's own cost and expense. Detailed plans showing facilities
and operating procedures to provide this protection shall be submitted
to the Authority for review by the Authority before construction of
the facility. All existing users shall complete such a plan when designated
by the Authority. No user who commences contribution to the POTW after
the effective date of this Part 5 shall be permitted to introduce
pollutants into the system until accidental and/or problem discharge
procedures have been approved by the Authority. 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 5. In the case of an accidental
or problem 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
or problem discharge, the user shall submit to the Authority a detailed
written report describing the cause of the discharge and the measures
to be taken by the user to prevent similar future occurrences. Such
notification shall not relieve the user of any expense, loss, damage
or 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 Part 5 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 accidental or problem discharge.
Employers shall ensure that all employees who may cause or suffer
such an accidental or problem discharge to occur are advised of the
emergency notification procedure.
D.
The Authority shall evaluate whether each SIU needs
an accidental discharge/slug discharge control plan or other action
to control slug discharges. The Authority may require any user to
develop, submit for approval, and implement such a plan or take such
other action that may be necessary to control slug discharges. An
accidental/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 Authority
or the Township of any accidental or slug discharge; 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 stored areas, the handling and transfer
of materials, loading and unloading operations, control of plant site
runoff, worker training, the building of containment structures or
equipment, measures for containing toxic organic pollutants, including
solvents, and/or measures and equipment for emergency response.
[Amended 9-27-2010 by Ord. No. 2010-06; 1-23-2017 by Ord. No. 2017-02; 1-22-2018 by Ord. No. 2018-001]
The following pollutant limits are established to protect pass-through
and interference. No person shall discharge wastewater at the point
where the wastewater is discharged to the POTW containing parameters
in excess of these limits:

|
Loadings associated with the overall limits for copper and zinc
are mass allocated as interim limits for individual significant industrial
users.
|
A.
Whenever deemed necessary, the Authority 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 POTW and determine the user's compliance
with the requirements of this Part 5.
B.
The Authority may require any person discharging into
the POTW to install and maintain, on its property and at its expense,
a suitable storage and flow control facility to ensure equalization
of flow. An individual wastewater discharge permit may be issued solely
for flow equalization.
C.
Grease, oil and sand interceptors shall be provided
when, in the opinion of the Authority, 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 a type and
capacity approved by the Authority and shall be so located to be easily
accessible for cleaning and inspection. Such interceptors shall be
inspected, cleaned and repaired by the user at its expense.
D.
Users with the potential to discharge flammable substances
may be required to install and maintain an approved combustible gas
detection meter at the user's expense.
