A.
Discharge of stormwater. No person shall discharge or cause or permit
to be discharged any stormwater, surface water, groundwater, artesian
well water, roof water, subsurface drainage, swimming pool drainage,
condensate, deionized water, noncontact cooling water, building foundation
drainage, and unpolluted wastewater into any sanitary sewer, unless
specifically authorized by the Township.
B.
Prohibited discharges. No user shall discharge or cause to be discharged,
directly or indirectly, any pollutant or wastewater that causes pass-through
or contributes to interference with the operation or performance of
the sewer system. These general prohibitions apply to all users, whether
or not the users are subject to federal categorical pretreatment standards
or any other federal, state or local pretreatment standards or requirements.
No person shall discharge the following substances to the sewer system:
(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 sewer system or to the operation of the sewer
system. At no time shall two successive readings on an explosion hazard
meter at the point of discharge into the sewer system (or at any point
in the sewer system) be more than 5%, nor any single reading be over
10%, of the lower explosive limit (LEL) of the meter. At no time shall
the closed-cup flashpoint of the wastewater be less than 140°F.
(60°C.) using test methods specified in 40 CFR 261.21. Prohibited
materials include, but are not limited to, the following substances
in concentrations which cause noncompliance with the above standard:
gasoline, kerosene, naphtha, benzene, ethers, alcohols, peroxides,
chlorates, perchlorates, bromates and carbides.
(2)
Solid or viscous substances which may cause obstruction to the
flow in a sewer or other interferences with the operation of the sewer
system, 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, and glass
grinding or polishing wastes.
(3)
Any wastewater having a pH less than 6.0 or more than 9.0, or
wastewater having any other corrosive property capable of causing
damage or hazard to structures, equipment and/or personnel of the
sewer system.
(4)
Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other constituents of the wastewater,
which injures or interferes with any wastewater treatment process,
constitutes a hazard to humans and animals, creates a toxic effect
in the receiving waters of the sewage treatment plant, or exceeds
the limitations set forth in an applicable federal categorical pretreatment
standard.
(5)
Any noxious or malodorous liquids, gases or solids which, either
singly or by interaction with other substances present in the sewer
system, are sufficient to create a public nuisance or hazard to life
or are sufficient to prevent entry into the sewer system for maintenance
and repair.
(6)
Any petroleum oil, nonbiodegradable cutting oil or products
of mineral oil origin in amounts that will cause interference or pass-through.
(7)
Fats, oils, greases or waxes of animal or vegetable origin in
concentrations greater than a daily maximum of 200 mg/l or a monthly
average of 100 mg/l.
(8)
Any substance that may cause the sewage treatment plant's effluent
or any other product of the sewage treatment plant, such as residues,
sludges or scums, to be unsuitable for reclamation or reuse, or to
interfere with the reclamation process. In no case shall a substance
discharged to the sewer system cause the sewage treatment plant to
be in noncompliance with sludge use or disposal criteria, guidelines
or regulations affecting sludge use or disposal developed pursuant
to the Solid Waste Disposal Act, the Clean Air Act, the Toxic Substance
Control Act, or state criteria applicable to the sludge management
method being used.
(9)
Any substance that will pass-through and, as a result, cause
the sewage treatment plant to violate its NPDES permit and/or state
collection system permit or applicable receiving water quality standards.
(10)
Any wastewater with objectionable color which will pass-through
the sewage treatment plant, such as, but not limited to, dye wastes
and vegetable tanning solutions.
(11)
Any wastewater having a temperature which will inhibit biological
activity in the sewage treatment plant, resulting in interference,
but in no case wastewater with a temperature at the introduction into
the sewage treatment plant which exceeds 104° F. (40° C.).
(12)
Any substance which results in the formation or release of toxic
gases, vapors or fumes in a quantity that may cause acute worker health
and safety problems.
(13)
Any trucked or hauled wastewater or pollutants, except those
discharged at points designated by the Township.
(14)
Any pollutants, including oxygen-demanding pollutants (BOD,
etc.) released at a flow rate and/or pollutant concentration that
will cause interference to the sewage treatment plant or interfere
with the operation of the sewer system.
(15)
Any wastewater containing any radioactive wastes or isotopes
of such half-life or concentration as may exceed limits established
by the Township or applicable state or federal regulations, cause
interference or otherwise adversely impact the sewage treatment plant
or cause or contribute to pollution.
(16)
Any wastewater, alone or in conjunction with other sources,
which is incompatible with treatment processes in use at the sewage
treatment plant so as to cause interference or pass-through or to
cause the treatment plant effluent to fail a toxicity test.
(17)
Any wastewater containing any compounds or salts of aldrin,
dieldrin, endrin, lindane, methoxychlor, toxaphene, dichlorophenoxyacetic
acid, trichlorophenoxyproprionic acid or other persistent herbicides,
pesticides or rodenticides.
(18)
Medical wastes, except as specifically authorized by the Township
in a wastewater discharge permit.
(19)
Detergents, surface-active agents or other substances that may
cause excessive foaming in the sewage treatment plant.
(20)
Sludges, screenings or other residues from the pretreatment
of industrial wastes.
Special agreements and/or waiver of pretreatment requirements.
Nothing contained in this chapter shall be construed as prohibiting
special agreements between the Township and a person discharging industrial
wastes or wastewaters to the sewer system, or for the Township to
otherwise waive requirements hereunder, when conditions and circumstances
making such special agreements or waiver advisable and/or necessary,
in the opinion of the Township, are present; provided, however, that:
A.
National categorical pretreatment standards, prohibitive discharge
standards [including the general and specific prohibitions set forth
at 40 CFR 403.5(a) and (b)] and other pretreatment requirements set
forth in 40 CFR 403 shall not be waived, unless such waiver is granted
by mechanisms established under the national pretreatment regulations
(40 CFR 403 et seq.).
B.
In no case shall a special agreement or waiver of local limits allow
for an industrial user to discharge any pollutant which, alone or
in combination with other regulated industrial user discharges, would
reasonably be expected to exceed the mass loadings determined by the
Township as acceptable to the sewage treatment plant based upon considerations
of, among other things, interference, pass-through and sludge contamination.
The Township may consider other factors (e.g., effect of the discharge
on the sewer system, future expansion, etc.), as it deems appropriate.
In no event shall special agreement or waiver allow the sum of the
loadings allocated to industrial users to exceed the values set forth
in any local limits analysis submitted by the Township to the EPA
and approved by the EPA as part of the industrial pretreatment program.
C.
The Township may require an industrial user requesting a special
agreement or waiver adjusting effluent limitations to submit supporting
documentation indicating why the industrial user cannot reasonably
expect to meet the effluent limitation contained in its wastewater
discharge permit, setting forth an expeditious schedule for achieving
compliance with such limitations and including such other information
as the Township may require. In granting any special agreement or
waiver, the Township may impose time limitations upon any reduced
requirements and provide a compliance schedule for achieving compliance.
In granting any special agreement or waiver, the Township may impose
any other conditions deemed necessary to implement the purposes of
this chapter.
D.
If granting a special agreement or waiver would result in increased
costs to the Township (e.g., treatment, monitoring, sludge disposal
costs), the Township may condition the special agreement or waiver
upon the agreement of the industrial user to pay those costs and to
provide security adequate in the judgment of the Township to assure
payment of said costs.
E.
Any special agreement and/or waiver of pretreatment requirements
under this section shall be memorialized in writing. "In writing"
includes, among other things, a wastewater discharge permit modification,
a written agreement, a letter from the Township to the industrial
user, an inspection report or any other written record which identifies
that the Township waived or otherwise modified the requirement.
A.
Federal categorical pretreatment standards. The federal categorical
pretreatment standards found at 40 CFR Chapter I, Subchapter N, §§ 405-471
are hereby incorporated by reference.
(1)
When regulated waste streams subject to a federal categorical
pretreatment standard are mixed with unregulated waste streams, the
Township may impose alternate limits using the combined waste stream
formula found in 40 CFR 403.6(e).
(2)
Where a federal categorical pretreatment standard is expressed
only in terms of either mass or concentration for a pollutant, the
Township may impose equivalent concentration or mass limits in accordance
with 40 CFR 403.6(c).
(3)
When the limits in a federal categorical pretreatment standard
are expressed only in terms of pollutant concentrations, an industrial
user may request that the Township convert the limits to equivalent
mass limits. The determination to convert concentration limits to
mass limits is within the discretion of the Township. The Township
may establish equivalent mass limits only if the industrial user meets
all of the conditions outlined in 40 CFR 403.6(c)(5) as 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 individual wastewater discharge permit;
[2]
Currently use control and treatment technologies adequate to
achieve compliance with the applicable federal 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 federal 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 whenever production rates are expected to increase by more than 20% from its baseline production rates determined in Subsection A(3)(a)[3] of this section. Upon notification of a revised production rate, the Township 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(3)(a)[1] and (a)[2] of this section so long as it discharges under an equivalent mass limit.
(c)
When developing equivalent mass limits, the Township:
[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 federal 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 individual 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 § 200-5.6 of this chapter. The industrial user must also be in compliance with § 200-9.3 of Article IX of these regulations.
[4]
The Township may not express limits in terms of mass for pollutants
such as pH, temperature, radiation, or other pollutants which cannot
appropriately be expressed as mass.
(4)
The Township may convert the mass limits of federal categorical pretreatment standards at 40 CFR 414, 419 and 455 to concentration limits for purposes of calculating limitations applicable to individual industrial users. When converting such limits to concentration limits, the Township will use the concentrations listed in the applicable subparts of 40 CFR 414, 419 and 455 and document that dilution is not being substituted for treatment as stated in § 200-5.6 of this chapter.
(5)
If a federal categorical pretreatment standard contains pretreatment
standards for both daily maximum and four-day average, the same production
or flow shall be used in calculating both daily maximum and four-day
average equivalent limitations in accordance with 40 CFR 403.6(c)(8).
(6)
Any industrial user subject to a wastewater discharge permit
containing equivalent concentration or mass limits calculated based
on a production standard shall notify the Township within two business
days after the industrial user has a reasonable basis to know that
the production level will significantly change within the next calendar
month. Any industrial user not notifying the Township of such change
will be required to comply with the concentration or mass equivalent
limits in its wastewater discharge permit that are based on the original
long-term average production rate in accordance with 40 CFR 403.6(c)(9).
(7)
An industrial user may obtain a variance from a federal categorical
pretreatment standard if the industrial user proves, pursuant to 40
CFR 403.13, that factors relating to its discharge are fundamentally
different from the factors considered by the EPA when developing the
federal categorical pretreatment standard.
(8)
An industrial user may obtain a net gross adjustment to a federal
categorical pretreatment standard in accordance with 40 CFR 403.15.
Federal categorical pretreatment standards may be adjusted to reflect
the presence of pollutants in the industrial user's intake water.
(9)
Where there is a conflict between federal, state or local pretreatment
standards, the more stringent pretreatment standard shall apply.
B.
Removal credits. Where the sewage treatment plant achieves consistent
removal of pollutants limited by categorical standards, the Township
may, at its sole discretion, apply to the approval authority for modification
of specific limits in the categorical standards as provided for in
40 CFR 403.7. Industrial user removal credit compensation for overflow,
if utilized, shall comply with 40 CFR 403.7(h) conditions.
C.
State requirements. State requirements and limitations on discharges
shall apply in any case where they are more stringent than federal
requirements and limitations or those established under this chapter.
A.
The Township may establish, review and revise from time to time local
limits regulating the discharge of specific pollutants by industrial
users.
(1)
Local limits may be established for any substance which is discharged,
or is likely to be discharged, to the sewer system.
(2)
Local limits may limit concentration, mass or a combination
of the two.
(3)
The procedure for the calculation of local limits may be as
recommended by the approval authority or otherwise considered appropriate
by the Township.
(4)
Local limits shall be calculated for pollutants, as deemed necessary,
to prevent interference and pass-through. In addition, local limits
may be calculated to prevent the discharge of toxic materials in toxic
amounts; threats to worker health and safety; and physical, chemical
or biological damage to the sewer system; or for such other purposes
as the Township deems appropriate.
(5)
Local limits are applicable to all significant industrial users
and may be included in wastewater discharge permits. Local limits
may be applied to other industrial users as deemed appropriate by
the Township.
(6)
Discharge of any pollutant by a significant industrial user,
or an industrial user subject to a local limit, in excess of a local
limit established for that pollutant shall constitute an unauthorized
discharge.
(7)
Local limits for industrial waste dischargers apply at the point
of discharge to the sewer system. All metals are considered "total
metal" unless otherwise indicated.

The Township reserves the right to establish through a wastewater
discharge permit more stringent limitations or requirements on discharges
to the sewer system, if deemed necessary and appropriate to comply
with the objectives presented in these regulations.
No industrial 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 discharge
limitations unless expressly authorized by the applicable pretreatment
standard or requirement. The Township may impose mass limitations
on industrial users who are using dilution to meet applicable pretreatment
standards or requirements or in other cases when the imposition of
mass limits is appropriate.
A.
Industrial users shall provide necessary wastewater treatment as required to comply with these rates, rules and regulations and shall achieve compliance with all federal categorical pretreatment standards, local limits and the prohibitions set out in §§ 200-5.1 and 200-5.2 of this chapter. Any facilities required to pretreat wastewater to a level acceptable to the Township shall be provided, operated and maintained at the industrial user's expense.
B.
Detailed plans showing the pretreatment facilities and operating
procedures shall be submitted to the Township for review and shall
be acceptable to the Township before construction of the facility.
The Township does not by its acceptance of any of the designs or installation
of the plans and equipment, or of any other information or plans submitted
by an industrial user, warrant or aver in any manner that the industrial
user's implementation of such measures will result in compliance with
the applicable pretreatment requirements. Notwithstanding any approval
of such plans by the Township, the industrial user remains solely
responsible for compliance with the applicable pretreatment standards
and requirements and all other federal, state and local requirements.
The review of such plans and operating procedures will in no way relieve
the industrial user from the responsibility of modifying the facility
as necessary to produce an acceptable discharge to the Township under
the provisions of these regulations. Any subsequent changes in the
pretreatment facilities or method of operation shall be reported to
and be accepted by the Township prior to the industrial user's initiation
of the changes.
C.
The industrial user shall at all times properly operate and maintain all pretreatment facilities and systems of treatment and control (and related appurtenances) which are installed or used by the industrial user to achieve compliance with pretreatment standards and requirements. This includes adequate laboratory controls and appropriate quality assurance procedures, the operation of backup or auxiliary facilities, or similar systems which are installed by the industrial user only when the operation is necessary to achieve compliance. The intentional diversion of waste streams from any portion of the industrial user's treatment facility is prohibited, except as provided by § 200-9.3B of these regulations.
Whenever deemed necessary, the Township may require an industrial
user to restrict its discharge during peak flow periods; to discharge
at a consistent flow rate; to discharge certain industrial wastewaters
only into specific sewers; to relocate and/or consolidate points of
discharge; to separate domestic wastewater from industrial wastewater;
and to perform and maintain such other conditions as may be necessary
to protect the sewage system and to determine the industrial user's
compliance with the requirements of these regulations. The Township
may require any person discharging into the sewer system to install
and maintain, on his/her property and at his/her expense, a suitable
storage and flow-control facility to ensure equalization of flow.
A wastewater discharge permit may be issued solely for flow equalization.
Industrial users with the potential to discharge flammable substances
may be required to install and maintain an acceptable combustible
gas detection meter.
A.
Upon notification from the Township, an industrial user shall provide
protection from accidental spills and slug load discharges of prohibited
materials or other substances regulated under these regulations, or
federal or state regulations and in accordance with 40 CFR 403.8(f)(1)(iii)(B)(6).
Facilities to prevent accidental spills or slug load discharges of
prohibited materials shall be provided and maintained at the industrial
user's own cost and expense. Detailed plans showing facilities and
operating procedures to provide this protection shall be submitted
to the Township for review and shall be subject to Township approval
before construction of the facility. All industrial users shall be
evaluated for the need to develop and implement an accidental discharge/slug
load control plan in accordance with requirements found at 40 CFR
403.8(f)(2)(vi) when designated by the Township. An accidental discharge/slug
load control plan shall address, at a minimum, the following provisions:
(1)
Description of discharge practices, including nonroutine batch
discharges.
(2)
Description of stored chemicals and material safety data sheets.
(3)
Procedures for immediately notifying the Township of any accidental
spill or slug load discharge.
(4)
Procedures to prevent adverse impact from any accidental spill
or slug load 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.
(5)
Such other conditions as deemed appropriate by the Township.
B.
PPC plans. Within 180 days of the adoption of this chapter, all existing
significant industrial users shall complete and obtain approval of
a preparedness, prevention and contingency (PPC) plan or provide acceptable
evidence that such a plan is not necessary for their facility. No
significant industrial user who commences discharge to the sewer system
after the effective date of this chapter shall be permitted to introduce
pollutants into the sewer system until this requirement has been fulfilled.
The Township, at its discretion, may require that a PPC plan be developed
by any other industrial user. PPC plans for significant industrial
users shall, at a minimum, contain the elements specified in the DEP's
Guidelines for the Development and Implementation of Environmental
Emergency Response Plans. PPC plans shall be submitted to the Township
for review and shall be accepted by the Township before implementation
of the plan or construction of any required facilities. Review and
approval of such plans, facilities and operating procedures by the
Township shall not relieve the industrial user from the responsibility
to modify its facility as necessary to meet the requirements of the
industrial pretreatment program. The review and approval of plans
and procedures by the Township shall not be considered as an approval
or determination regarding their efficacy, safety or reliability;
such considerations are solely the responsibility of the industrial
user.
A.
Discharge of trucked or hauled wastes shall only be made at a point
designated by the Township, and such waste shall not violate these
regulations or any other requirements established by the Township.
B.
No trucked or hauled wastes may be discharged except as specifically
approved by the Township. The Township may require testing, reporting
or other specific information to be presented by the operator or owner
prior to discharge.
A.
Drainage of water-filtration systems. Discharge of filter backwash
water to the sewer system shall be regulated as follows:
(1)
Granular media (e.g., sand) filter backwash water may be discharged
to the sewer system, subject to all of the applicable provisions of
this chapter.
(2)
Diatomaceous earth filter backwash, if discharged to the sewer
system, shall be connected to the sewer system through settling tanks
with no less than three months' storage capacity of spent diatomaceous
earth, which tanks shall be accessible for removing solid waste for
disposal.
B.
Privy vaults, cesspools, sinkholes and septic tanks.
(1)
No privy vault, cesspool, sinkhole, septic tank or similar receptacle shall be used and maintained at any time upon any improved property which has been connected to a sewer or which shall be required under Article III of these regulations to be connected to a sewer.
(2)
Every such privy vault, cesspool, sinkhole, septic tank or similar
receptacle in existence shall be abandoned and, at the discretion
of this Township, shall be cleansed and filled under the direction
and supervision of this Township; and any such privy vault, cesspool,
sinkhole, septic tank or similar receptacle not so abandoned and,
if required by this Township, 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.
(3)
No privy vault, cesspool, sinkhole, septic tank or similar receptacle
shall at any time be connected to a sewer.
C.
Floor drains.
(1)
Basement floor drains shall not be permitted to be connected
to the building sewer except where it can be shown to the satisfaction
of the Township that the connection is absolutely necessary.
(2)
A permit shall be obtained from the Township before any floor
drain may be attached to the building sewer drainage system.
(3)
No permit for a basement floor drain shall be granted until
the owner of the building or his/her agent has executed, signed and
filed with the Township a written statement releasing the Township
from any damage or personal injury that may result.
