A.
No user shall contribute or cause to be contributed, directly or
indirectly, any pollutant or wastewater which will cause pass-through
or interfere with the operation or performance of the POTW. These
general prohibitions apply to all such users of a POTW whether or
not the user is subject to National Categorical Pretreatment Standards
or Requirements. A user may not contribute the following substances
to any 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 other
substances to cause fire or explosion or be injurious in any other
way to the POTW or to the operation of the POTW. These substances
include but are not limited to wastestreams with a closed-cup flashpoint
of less than 140° F. 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 system (or at any
point in the system), be more than 5% or 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 substances which the control authority, the state or
approved authority has notified the user is a fire hazard or a hazard
to the collection or treatment 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
particle greater than one-half 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 5.0, unless the POTW is specifically
designed to accommodate such wastewater, or wastewater having any
other corrosive property capable of causing damage or hazard to structures,
equipment and/or personnel of the POTW.
(4)
Any wastewater containing toxic pollutants or pollutants which result
in the presence of toxic gases, vapors or fumes in sufficient quantity,
either singly or by interaction with other pollutants, to injure or
interfere with any wastewater treatment process or cause injury, worker
health and safety problems, 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 sewers for maintenance and repair.
(6)
Any substance which may cause the POTW's effluent or any other product
of the POTW, such as residues, sludge or scum, 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 pass-through or
interference, but in no case wastewater with a temperature at the
introduction into the POTW which exceeds 40° C. (104° F.)
unless USEPA has approved alternate limits as requested by the POTW.
(10)
Any pollutants, including oxygen-demanding pollutants (BOD,
etc.), released at a flow rate and/or pollutant concentration which
a user knows or has reason to know will cause pass-through or interference
to the POTW. In no case shall a slug load have a flow rate or contain
concentration or quantities 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 as may exceed limits established
by the Superintendent in compliance 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 pass-through or interference
of the POTW.
(14)
Any trucked or hauled pollutants, except at discharge points
designated by THTMA.
B.
When THTMA determines that a user is contributing to the POTW any of the above-enumerated substances in such amounts as to cause pass-through or interference of the POTW, the control authority shall advise the user of the impact of the contribution on the POTW; develop effluent limitations for such user to correct the problem of pass-through or interference of the POTW. THTMA may pursue an enforcement action, as outlined in Article IX, Administrative Enforcement Remedies, of this Part 3 against the industrial user in the event that the user causes pass-through or interference.
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 3 for sources in that subcategory, shall immediately supersede the limitations imposed under this Part 3. The categorical pretreatment standards found in 40 CFR Chapter 1, Subchapter N, Parts 405-471, are incorporated herein by reference. The control authority shall notify all affected users of the applicable reporting requirements under 40 CFR 403.12 and shall provide copies of any such written notices to UTMA.
A.
Where the POTW treatment plant achieves consistent removal of pollutant(s)
discharged by an industrial user to which a categorical pretreatment
standard(s) applies, THTMA may, at its discretion and subject to the
conditions of 40 CFR 403.7, make application to the approval authority
for permission to grant removal credits to reflect removal by the
POTW of pollutants specified in the categorical pretreatment standard(s).
The control authority may grant a removal credit equal to or, at its
discretion, less than its consistent removal rate. Upon being granted
a removal credit, each affected industrial user shall calculate its
revised discharge limits in accordance with 40 CFR 403.7(a)(4).
B.
Consistent removal shall mean the average of the lowest 50% of the
removal measured according to 40 CFR 403.7(b)(2). All sample data
obtained for the measured pollutant during the time period prescribed
in 40 CFR 403.7(b)(2) must be reported and used in computing consistent
removal. If a substance is measurable in the influent but not in the
effluent, the effluent level may be assumed to be the limit of measurement,
and those data may be used by the POTW at its discretion and subject
to approval by the approval authority. If the substance is not measurable
in the influent, the data may not be used.
C.
The POTW may grant removal credits only if:
(1)
The POTW applies for and receives authorization from the approval
authority to give a removal credit in accordance with the requirements
and procedures specified in 40 CFR 403.7(e);
(2)
The POTW demonstrates and continues to achieve consistent removal
of all the pollutant(s) in accordance with 40 CFR 403.7(b);
(3)
The POTW has an approved pretreatment program in accordance with
and to the extent required by 40 CFR 403;
(4)
The granting of removal credits will not cause the POTW to violate
the local, state and federal sludge requirements which apply to the
sludge management method chosen by the POTW; and
(5)
The granting of removal credits will not cause a violation of the
POTW's permit limitation or conditions.
D.
THTMA may then 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.
[Amended 7-28-1998 by Ord. No. O-2-98]
No industrial user shall discharge wastewater containing a mass
of any pollutant which, when taken together with the mass of that
pollutant discharged by all other industrial users, will cause the
mass of the pollutant to exceed the mass of that pollutant specified
in the headworks industrial allowance which has been approved by the
approval authority for the POTW treatment plant into which the industrial
user discharges.
State requirements and limitations on discharges shall apply
in any case where they are more stringent than federal requirements
and limitations on those in this Part 3.
Unity Township reserves the right to establish by ordinance
more stringent limitations or requirements on discharges to the wastewater
disposal system if deemed necessary, in its discretion.
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 Unity Township,
THTMA or the state. Dilution is permitted only where expressly authorized
by an applicable pretreatment standard or requirement.
A.
Each significant industrial user shall provide protection from accidental
or slug discharges of prohibited materials or other substances regulated
by this Part 3. Facilities to prevent accidental or slug discharges
of prohibited materials shall be provided and maintained at the owner
or user's own cost and expense. Detailed plans showing facilities
and a complete description of operating procedures implemented to
provide this protection shall be submitted to THTMA prior to construction
of the facility. All existing significant industrial users shall have
completed the aforementioned plan as required by this Part 3. No industrial
user who commences contribution to the POTW after the effective date
of this Part 3 shall be permitted to introduce pollutants into the
system until accidental discharge procedures have been approved by
THTMA. Review and approval of such plans and operating procedures
shall not relieve the industrial user from the responsibility to modify
the industrial user's facility as necessary to meet the requirements
of this Part 3.
B.
A complete description of operating procedures must include but not
be limited to the following:
(1)
A listing of all stored chemicals, including the type and nature
of the chemical, maximum quantity stored and any safety procedures
to be followed if an accidental discharge occurs.
(2)
A description of discharge practices, including nonroutine batch
discharges.
(3)
A description of procedures to prevent adverse impact from accidental
or slug discharges, including but not limited to inspection and maintenance
of storage areas, handling and transfer of materials, loading and
unloading operations, control of site runoff, employee training, building
of containment structures or equipment for emergency response.
A.
In the case of accidental or slug discharge or any discharge that
could cause problems at the POTW, it is the responsibility of the
industrial user to immediately telephone and notify the POTW of the
incident. The notification shall include location of discharge, type
of waste discharged, concentration and volume of waste discharged
and corrective actions.
B.
Within five days following an accidental or slug discharge, the industrial
user shall submit to THTMA a detailed written report describing the
cause of the discharge and the measures taken by the industrial user
to prevent similar future occurrences. Such notification shall not
relieve the industrial user of any expense, loss or damage to the
POTW, fish kills or any other damage to person or property; nor shall
such notification relieve the industrial user of any fines, civil
penalties or other liability which may be imposed by this Part 3 or
other applicable law.
A notice shall be permanently posted on the industrial user's
bulletin board or other prominent location advising employees whom
to contact in the event of an accidental or slug discharge. Employers
shall ensure that all employees are advised of the emergency notification
procedure.
THTMA shall, at least once every two years, evaluate each industrial
user served by THTMA to determine if that industrial user will be
required to develop a plan to control accidental or slug discharges.
