[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
No person shall discharge or cause or permit to be discharged
any stormwater, surface water, groundwater, roofwater, subsurface
drainage, or building foundation drainage into any sanitary sewer.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. No user shall discharge or cause to be discharged, directly or indirectly,
any pollutant or wastewater which will Interfere with the operation
or performance of the sewer system. These general prohibitions apply
to all users whether or not the users are subject to categorical standards
or any other pretreatment requirements. A user may not discharge the
following substances to the sewer system:
A. 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 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. At no time shall the closed-cup
flashpoint of the wastewater be less than 140° F. Prohibited materials
include, but are not limited to, the following substances in concentrations
which cause exceedance of the above standard: gasoline, kerosene,
naphtha, benzene, ethers, alcohols, peroxides, chlorates, perchlorates,
bromates, and carbides.
B. Solid or viscous substances which may cause obstruction to the flow
in a sewer or other interference 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, or glass
grinding or polishing wastes.
C. Any wastewater having a pH less than 6.0 or higher than 10.0, or
wastewater having any other corrosive property capable of causing
damage or hazard to structures, equipment, and/or personnel of the
sewer system.
D. Any wastewater containing toxic pollutants in sufficient quantity,
either singly or by interaction with other constituents of the wastewater,
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 sewage treatment plant, or to exceed the limitation
set forth in an applicable categorical standard.
E. Any noxious or malodorous liquids, gases, or solids which either
singly or by interaction with other substances normally 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.
F. Any substance which results in the formation or release of toxic
gasses, vapors or fumes in a quantity that may cause acute worker
health and safety problems.
G. Any petroleum oil, nonbiodegradable cutting oil, or products of mineral
oil origin in amounts that will cause interference or pass through,
but in no case exceeding 20 mg/L.
H. Fats, oils, greases or waxes of animal or vegetable origin in amounts
which cause interference with the POTW, including but not limited
to physical obstruction of sewers.
I. Any substance which 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 and 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 Substances Control Act, or state criteria applicable to the sludge management
method being used.
J. Any substance which will cause the Authority to violate its NPDES
and/or state collection system permit or applicable receiving water
quality standards.
K. Any wastewater with objectionable color which will pass through the
treatment plant, such as, but not limited to, dye wastes and vegetable
tanning solutions.
L. 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 discharge into
the sewer system which exceeds 40° C. (104° F.).
M. Any pollutants, including oxygen-demanding pollutants (BOD, etc.),
released at a flow rate and/or pollutant concentration which will
cause interference to the sewage treatment plant or interfere with
the operation of the sewer system. BOD in excess of 1,500 mg/l in
a composite sample and 2,250 mg/l in any grab sample is prohibited.
In no case shall a slug load be discharged.
N. 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.
O. Any trucked or hauled wastewater or pollutants except those discharged
at points designated by the Authority.
P. Any wastewater which is incompatible with treatment processes in
use at the sewage treatment plant so as to cause interference or pass
through.
Q. 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.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
Discharge of any prohibited substance listed under §
18-205 shall be considered an unauthorized discharge, and the Township may take whatever steps are necessary to halt such a discharge, as set forth in Subparts F and G of this Part.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. If the categorical standards for a particular industrial user are
more stringent than local limits or other requirements imposed under
this Part, then the categorical standards shall apply. The Township
shall notify all affected industrial users of the applicable reporting
requirements under 40 CFR 403.12. The national categorical pretreatment
standards are hereby incorporated into the industrial pretreatment
program as program requirements for those industrial users subject
to such categorical standards.
2. When the limits in a categorical pretreatment standard are expressed only in terms of pollutant concentrations, the Township may implement the limits as equivalent mass limits. An industrial user may request equivalent mass limits from the Township in writing. Upon receiving such a request, the Township will determine if the industrial user meets the eligibility criteria for mass limits as listed in §
18-207, Subsection
2A(1) through
(5), below. The Township may determine that an industrial user meets the criteria, but choose not to implement the limits as equivalent mass requirements based on other considerations.
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 control mechanism;
(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 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 control authority whenever production rates are expected to vary by more than 20% from its baseline production rates determined in Subsection
2A(3) of this section. Upon notification of a revised production rate, the control authority must 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
2A(1) of this section so long as it discharges under an equivalent mass limit.
C. When establishing 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 categorical pretreatment standard
and the appropriate unit conversion factor;
(2)
Will, upon notification of a revised production rate, 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 control mechanism 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 §
18-211. The industrial user must also be in compliance with §
18-218 (regarding the prohibition of bypass).
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
Where the sewage treatment plant achieves consistent removal
of pollutants limited by categorical standards, the Township may apply
to the Approval Authority for modification of specific limits in the
categorical standards. If the requirements contained in 40 CFR 403.7
are fulfilled and prior approval from the Approval Authority is obtained,
the Township may then modify pollutant discharge limits in the categorical
standards.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
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 Part.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. The Township may establish local limits regulating the discharge
of specific pollutants by industrial users.
A. Local limits may be established for any substance which is discharged,
or is likely to be discharged, to the sewer system.
B. Local limits may limit concentration, mass, or a combination of the
two.
C. The procedure for the calculation of local limits should be as recommended
by the Approval Authority. Whenever possible, the calculation of local
limits shall be technically based, using all available information.
D. Local limits shall be calculated to prevent interference; pass through;
the discharge of toxic materials in toxic amounts; threats to worker
health and safety; and physical, chemical or biological damage to
the sewer system.
E. Local limits shall be applied to all significant industrial users
and shall be included in all wastewater discharge permits. Local limits
may be applied to other industrial users if deemed appropriate by
the Township.
F. Discharging any pollutant in excess of a local limit established
for that pollutant shall constitute an unauthorized discharge. Such
a discharge is subject to the actions and penalties set forth herein.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
No industrial user shall, in any way, attempt to dilute a discharge
as a partial or complete substitute for adequate pretreatment to achieve
compliance with the limitations contained in applicable categorical
standards, or in any other pollutant-specific limitation, including
local limits, developed by the Township or state.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. Each industrial user shall provide protection from spills or accidental
discharges that result in unauthorized discharges or slug load discharges.
Facilities to prevent spills and slug loads shall be provided and
maintained at the owner or industrial user's own cost and expense.
A. Notification.
(1)
In the case of a spill or slug load or other unauthorized discharge,
it is the responsibility of the industrial user to immediately telephone
and notify the Superintendant of the incident. The notification shall
include location of discharge, type of waste, concentration and volume,
corrective actions being taken or planned, and expected duration.
(2)
In the event a change is made at a facility that affects the
potential for discharge of a spill or slug load or other unauthorized
discharge, the industrial user shall immediately notify the Township
of the change.
B. Notice to Employees. A notice shall be permanently posted on the
industrial user's bulletin board or other prominent place advising
employees who to call in the event of a spill or other unauthorized
discharge. Employers shall ensure that all employees who may cause
or suffer such a discharge to occur are advised of the emergency notification
procedure.
C. Written Notice. Within five days following a spill, slug load, or
other unauthorized discharge, the industrial user shall submit to
the Township a detailed written report describing the cause of the
discharge and the measures to be taken by the industrial user to prevent
similar future occurrences. Such notification shall not relieve the
industrial user of any expense, loss, damage, or other liability which
may be incurred as a result of damage to the sewer system, fish kills,
or any other damage to persons 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 or applicable law.
D. SPCC Plans. All existing significant industrial users shall complete
and obtain approval of a spill prevention control and countermeasure
(SPCC) 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 Part
shall be permitted to introduce pollutants into the sewer system until
this requirement has been fulfilled. Industrial users other than significant
industrial users may be required to submit as SPCC plan at the discretion
of the Township. Such plans shall, at a minimum, contain the elements
specified in 40 CFR 403.8(f)(2)(vi)(A) through (D). SPCC plans shall
be submitted to the Township for review, and shall be approved 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.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. Discharge of filter backwash water to the sewer system shall be regulated
as follows:
A. Granular media filter backwash water may be discharged to the sewer
system, subject to all of the applicable provisions of this Part.
B. 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.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. Discharge of trucked or hauled wastes shall be made at a point designated
by the Authority.
2. Such wastes shall conform to all requirements of the industrial pretreatment
program regarding prohibited discharges, regulated characteristics,
local limits, or other requirements as to nature and concentration.
3. No trucked or hauled wastes shall be discharged except as specifically
approved by the Authority. The Township and/or Authority may require
testing, reporting, or other specific information to be presented
by the operator or owner prior to discharge.
4. In order to implement the provisions of Subsection
3 of this section, the Township and/or Authority may establish a permit system or other means of control, and may set rate, frequency, volume, or other controls on the discharges from such vehicles.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
Grease, oil and sand interceptors or traps shall be provided
by a user when the Township determines that such devices are necessary
for the proper handling of wastewaters containing greases, oils or
settleable solids. Interceptors and traps shall be installed, operated,
maintained and cleaned properly so that they will consistently remove
the grease, oil or settleable solids. Interceptors and traps shall
be properly designed to accommodate the maximum flow rate expected
to occur and shall be located as to be readily and easily accessible
for cleaning and inspection.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
The use of mechanical garbage grinders producing a finely divided
mass, properly flushed with an ample amount of water, shall be permitted,
upon the condition that no such mechanical garbage grinder used for
commercial or business purposes shall be installed until permission
for such use has been obtained from the Township.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. All industrial users shall notify the Township, the EPA Regional
Waste Management Division Director, and the Pennsylvania Department
of Environmental Protection, Bureau of Waste Management, in writing,
of any discharge into the POTW of a substance which, if otherwise
disposed of, would be a hazardous waste under 40 CFR Part 261. Such
notification shall include the name of the hazardous waste, as set
forth in 40 CFR Part 261, the EPA hazardous waste number, and the
type of discharge (continuous, batch, or other). If the industrial
user discharges more than 100 kilograms of such waste per calendar
month, the notification shall also include the following information,
to the extent that it is known and readily available to the industrial
user:
A. An identification of the hazardous constituents contained in the
waste;
B. An estimation of the mass and concentration in the wastewater of
all such constituents discharged in the most recent month; and
C. An estimate of the mass and concentration of such constituents expected
to be discharged during the following 12 months.
2. Industrial users that commence discharge after the effective date of this Part shall submit the report within 180 days of first discharge of the hazardous waste, except as provided in Subsection
4 of this section.
3. The required report need be submitted only once for each hazardous
waste discharged. Industrial users regulated under categorical standards
which have already submitted such information in baseline monitoring
reports or periodic compliance reports do not have to report this
information again.
4. Industrial users that discharge less than 15 kilograms of hazardous
wastes in a calendar month do not have to comply with these reporting
requirements. This exemption does not apply to acute hazardous wastes
as specified in 40 CFR 261.30(d) and 261.33(e).
5. An industrial user shall notify the Township within five days of
becoming aware of any discharges of reportable quantities of listed
or unlisted hazardous substances, as defined at 40 CFR 302.4 (CERCLA
Hazardous Substances). This notification shall include the time of
release; the name of the substance; the identifying CAS number, if
known; and the approximate quantity discharged. If the discharge constitutes
a spill, change in wastewater constituents, or slug load, other reporting
requirements of the industrial pretreatment program may also apply.
6. Each notification required by this section shall include a statement
certifying that the industrial user has a program in place to reduce
the volume and/or toxicity of the discharged wastes to the extent
that it is economically practical. This statement shall be signed
by the authorized representative of the industrial user.
[Ord. No. 5/11/1993; as amended by Ord. No. 3-2007, 8/14/2007]
1. Bypass is prohibited, and the Township may take enforcement action
against an industrial user for a bypass, unless;
A. Bypass was unavoidable to prevent loss of life, personal injury,
or severe property damage. "Severe property damage" means substantial
physical damage to property, damage to the treatment facilities which
causes them to become inoperable, or substantial and permanent loss
of natural resources which can reasonably be expected to occur in
the absence of a bypass. "Severe property damage" does not mean economic
loss caused by delays in production.
B. There were no feasible alternatives to the bypass, such as the use
of auxiliary treatment facilities, retention of untreated wastes,
or maintenance during normal periods of equipment downtime. This condition
is not satisfied if adequate backup equipment should have been installed
in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventative
maintenance; and
C. The industrial user submitted notices as required under Subsection
3 of this section.
2. An industrial user may allow any bypass to occur which does not cause pretreatment standards or requirements to be violated, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Subsections
1,
3 and
4 of this section.
3. If an industrial user knows in advance of the need for a bypass,
it shall submit prior notice to the Township, if possible at least
10 days before the date of the bypass. The Township may approve an
anticipated bypass, after considering its adverse effects, if the
Township determines that it will meet the three conditions listed
in Subsesction 1A through C of this section.
4. An industrial user shall submit oral notice of an unanticipated bypass
that exceeds applicable pretreatment standards to the Township within
24 hours of the time the industrial user becomes aware of the bypass.
A written submission shall also be provided within five days of the
time the industrial user becomes aware of the bypass. The written
submission shall contain a description of the bypass and its cause;
the duration of the bypass, including exact dates and times and, if
the bypass has not been corrected, the anticipated time it is expected
to continue; and steps taken or planned to reduce, eliminate, and
prevent reoccurrence of the bypass. The Township may waive the written
report on a case-by-case basis if the oral report has been received
within 24 hours.
