[Adopted 10-7-2014 by Ord. No. 14-19]
A.
Findings. It is found and declared:
(1)
The purpose of this article is the regulation of the generation and
disposal of oil and grease interceptor/trap waste, for the protection
of the Borough of Runnemede infrastructure and the environment.
(2)
Grease interceptors/traps have malfunctioned even when the systems
have been designed, constructed, and sited in accordance with applicable
standards, largely due to lack of proper systems management or improper
operation and maintenance. These malfunctions have been shown to adversely
affect public health and welfare and the environment. Such systems
constitute a potential source of pollution of ground waters and surface
waters, contamination of potable water supplies, foul odors, nuisance
problems and other hazards to public health.
(3)
It is determined to be in the interest of public health, safety and
welfare to establish provisions to regulate the installation and management
of such systems in conjunction with the Borough of Runnemede to protect
the public against construction and maintenance failures and the resultant
pollution.
(4)
The permit provisions contained herein are necessary to protect the
public health, safety and welfare as set forth in N.J.A.C. 7:9A-1
et seq.
B.
Purpose. In addition to the purposes set forth in N.J.A.C. 7:9A-1.1,
it is the purpose of this article:
(1)
To establish a construction management program for individual and
nonindividual grease Interceptors/Traps in the Borough of Runnemede
in order to ensure the proper construction, operation and maintenance
of such systems. This article requires existing, new and proposed
individual and nonindividual grease interceptors/traps to be pumped
out at least once every year in order to minimize future malfunctions
of such systems.
(2)
To regulate individual and nonindividual grease interceptors/traps
in such a way as to protect public health and welfare and the environment,
and to provide for a means of educating owners/operators in the characteristics
of such systems and the proper procedures for constructing, altering,
operating and maintaining same.
(3)
To develop a construction management program to maintain records
and manage systems.
(4)
To promote and ensure the proper construction management and maintenance
of individual and nonindividual sewage disposal systems through time.
A.
Except as otherwise provided herein, the Borough shall implement,
and enforce the provisions of this article.
B.
The Borough Clerk, the Borough Engineer, the Director of Public Works,
the Runnemede Sewer Utility or its Supervisors are persons designated
and under the instruction and supervision of any of them, may investigate
compliance of this article.

at a location conducting, supervising, managing, or representing the
activities of a generator, a transporter or a disposer.
Any building, structure, facility, or installation from which
there is (or may be) a discharge of pollutants, the construction of
which commenced after the adoption of this article, provided that:
The building structure, facility, or installation is constructed
at a site at which no other source is located; or
The building, structure, facility, or installation totally replaces
the process or production equipment that causes the discharge of pollutants
at an existing course; or
The production processes or wastewater generating processes
of the building, structure, facility, or installation are substantially
independent of an existing source at the same site. In determining
whether these are substantially independent, factors such as the extent
to which the new facility is integrated with the existing plant, and
the extent to which the new facility is engaged in the same general
type of activity as the existing source, should be considered; or
Any remodeling or modification that results in a new facility
as determined by the Borough.
Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility, or installation meeting the criteria of Subsection (1)(b) or (c) above, but otherwise alters, replaces, or adds to existing process or production equipment.
Construction of a new source as defined under this subsection
has commenced if the owner or operator has:
Begun, or caused to begin, as part of a continuous on-site construction
program any placement, assembly, or installation of facilities or
equipment; or significant site preparation work, including clearing,
excavation, or removal of existing buildings, structures, or facilities
which is necessary for the placement, assembly, or installation of
new source facilities or equipment; or
Entered into a binding contractual obligation for the purchase
of facilities or equipment, which are intended to be used in its operation
within a reasonable time. Options to purchase or contracts which can
be terminated or modified without substantial loss, and contracts
for feasibility, engineering, and design studies do not constitute
a contractual obligation under this subsection.
National Pollutant Discharge Elimination System as administered
by the United States Environmental Protection Agency.
Any time during which a facility is open for business to
the public. It shall also include those times when a facility is closed
to the public when a manager, employees, and/or contractors are present
at the facility and involved in cleanup or food preparation, or any
other business activity.
The liquid and water-carried domestic or industrial wastes
from dwellings, commercial establishments, industrial facilities and
institutions, whether treated or untreated. The terms "waste" and
"wastewater" shall be deemed as sewage by definition.
The unpermitted, accidental or intentional loss or unauthorized
discharge of grease interceptor/trap waste, grit interceptor waste,
seepage, any other liquid waste, a chemical (hazardous or nonhazardous),
or any other material that has the potential to contaminate any surface
or ground water or in any other manner such that the waste is not
duly and legally disposed.

to be in the possession of the generator, transporter, and disposer
to document the generation, receipt, transportation, and disposal
of grit interceptor waste, grease interceptor/trap waste, seepage,
and other liquid wastes enabling legal and proper disposal of hauled
grit interceptor waste, grease interceptor/trap waste, and seepage
at a permitted or registered disposal site, and specifying the identity
of the generator, transporter, and disposal facility operator of liquid
wastes and the volume of grit interceptor waste, grease interceptor/trap
waste, seepage, and other liquid wastes disposed.
A device placed under or in close proximity to sinks or other
fixtures likely to discharge grease in an attempt to separate, intercept
or hold grease waste to prevent its entry into the Borough of Runnemede
infrastructure.
The liquid and water-carried domestic or industrial wastes
from dwellings, commercial establishments, industrial facilities and
institutions, whether treated or untreated. The terms "sewage" and
"wastewater" shall be deemed as waste by definition.
B.
Word usage. When the terms "may not" and "shall not" are used in
this article, they shall be construed to mean that the action referred
to is prohibited.
A.
Waste, which contains fats, oil, or grease, shall be discharged into
the Borough of Runnemede infrastructure only under the conditions
of this article. The following facilities shall discharge all waste
from sinks, dishwashers, drains, and any other fixtures through which
oil or grease may be discharged, into an adequately sized, properly
maintained and functioning grease interceptor/trap as authorized and
accepted by the Borough of Runnemede before the discharge enters the
Borough of Runnemede infrastructure, as well as providing a grease
interceptor/trap inlet flow-control device inspection port and a grease
interceptor/trap effluent monitoring port:
(1)
Every commercial food preparation and food service facility, including
but not limited to bakeries, boardinghouses, butcher shops, cafes,
clubhouses, commercial kitchens, delicatessens, ice cream parlors,
hospitals, restaurants, schools, and similar facilities, especially
where meat, poultry, seafood, dairy products or fried foods are prepared
or served.
(2)
All shopping centers and/or strip malls that have food processing
facilities.
(3)
All food courts.
(4)
All other facilities discharging grease in amounts that, in the opinion
of the Borough of Runnemede, will, alone or in concert with other
substances from the discharges of other facilities, have a reasonable
chance to impede or stop the flow of the Borough of Runnemede infrastructure.
B.
All new areas of intensified dwelling, including but not limited
to adult day-care facilities, assisted living facilities, convalescent
homes, day nursing and child-care facilities, in which food preparation
occurs as defined, homes for the mentally challenged, hotels, maternity
homes, motels in which there is a commercial food preparation service,
nursing homes, retirement and life-care communities and homes, and
truck stops with commercial food service, shall be required to have
grease interceptors/traps.
C.
Interceptors/traps shall not be required for single-family residences,
duplexes, triplexes, quadplexes, or apartment complexes, unless the
Borough of Runnemede first determines there are discharges from the
property that will affect the Borough of Runnemede infrastructure.
The determination shall be made based upon an investigation of the
property and a comparison of the content and amount of discharge from
the property with the discharges of other properties similar in size
and use. Upon a determination that the discharges will create problems,
the Borough of Runnemede may require the installation of a sufficiently
sized grease interceptor/trap to treat the discharges.
A.
On or after the effective date of the ordinance codified in this article, an existing facility (excepting those existing facilities described in § 292-13C above) shall be required to install an approved, adequately sized, and properly operated and maintained grease interceptor/trap when any of the following conditions exist:
(1)
It is found by the Borough of Runnemede to be contributing grease
in quantities sufficient to cause sanitary sewer line stoppages or
necessitate increased maintenance on the sanitary sewer collection
system in order to keep main line stoppages from occurring.
(2)
The existing interceptors/traps allow a discharge of fats, oil, or
grease in excess of 100 milligrams per liter.
B.
Existing facilities required by this article or other applicable
ordinances to maintain a grease interceptor/trap equipped with an
undersized grease interceptor/trap shall only be required to correct
the condition when it is determined that their interceptor/trap is
contributing grease in quantities sufficient to cause sanitary sewer
line stoppages or necessitate increased maintenance on the sanitary
sewer collection system in order to keep main line stoppages from
occurring.
C.
Existing facilities required by this article or other applicable
ordinances to maintain a grease interceptor/trap not equipped with
a grease interceptor/trap shall only be required to correct the condition
when it is determined that their interceptor/trap is contributing
grease in quantities sufficient to cause sanitary sewer line stoppages
or necessitate increased maintenance on the sanitary sewer collection
system in order to keep main line stoppages from occurring.
D.
New facilities required by this article or other applicable ordinances
to maintain a grease interceptor/trap shall install such a unit prior
to commencement of discharge into the Borough of Runnemede infrastructure.
E.
Any requests for extensions of installation dates must be made in
writing to the Borough Clerk, with a copy to the Business Administrator
of the Borough of Runnemede, at least 30 days in advance of the compliance
date. The written request shall include the reasons for the grease
generator's failure or inability to comply with the compliance
date set forth, the additional time needed to complete the remaining
work, and the steps to be taken to avoid future delays. The Borough
of Runnemede shall determine the date for compliance.
A.
Where fats, oil and grease are a byproduct of food preparation and/or
cleanup, reasonable efforts shall be made to separate waste fats,
oil, and grease into a separate container for proper disposal. Except
as contained in byproducts of food preparation and/or cleanup, waste
fats, oil, and grease shall not be discharged to any drains or grease
interceptors/traps. Such waste shall be placed in a container designed
to hold such waste and either utilized by industry or disposed of
at suitable locations.
B.
None of the following agents shall be placed directly into a grease
interceptor/trap, or into any drain that leads to the interceptor/trap:
(1)
Emulsifiers, de-emulsifiers, surface active agents, enzymes, degreasers,
or any type of product that will liquefy grease interceptor/trap wastes;
(2)
Any substance that may cause excessive foaming in the Borough of
Runnemede infrastructure; or
(3)
Any substance capable of passing the solid or semisolid contents
of the grease interceptor/trap to the Borough of Runnemede infrastructure.
C.
The influent to interceptors/traps shall not exceed 140° F. The
temperature at the flow-control device inspection port shall be considered
equivalent to the temperature of the influent.
D.
Toilets, urinals, and other similar fixtures shall not discharge
through a grease interceptor/trap.
E.
All waste shall only enter the grease interceptor/trap through the
inlet flow-control device, then the inlet pipe.
F.
Where food waste grinders are installed, the waste from those units
shall discharge directly into the building drainage system without
passing through a grease interceptor/trap. Living quarters, as defined
in this article, are exempted from this requirement.
A.
All commercial and industrial facilities dealing with grease shall,
at the permittees' expense and as required by the Borough of
Runnemede:
(1)
Provide an adequately sized grease interceptor/trap. Requirements for grease trap sizing and the design criteria are provided in Subsection B below.
(2)
Locate the interceptor/trap in a manner that provides ready and easy
accessibility for cleaning and inspection.
(3)
Obtain a written interceptor/trap service agreement with a licensed
transporter for a term of at least one year, or for the duration of
the operation of the establishment, whichever is less, to maintain
the interceptor/trap in effective operating condition. A service agreement
must be in effect as long as the facility has a grease trap permit.
(4)
Unless otherwise specified by the Borough of Runnemede, service the
interceptor/trap every 90 days and maintain backup copies of trip
tickets and a service log, on the premises of the facility, for at
least five years.
(5)
Allow demand inspection of the facility and of records by inspectors
during reasonable hours.
B.
Requirements for grease trap sizing and design criteria.
(1)
Introduction: Shall be in accordance with the requirements and recommendations
of the Borough Engineer, as well as standard industry practices and
guidance found in the United States Environmental Protection Agency
Design Manual for Onsite Wastewater Treatment and Disposal Systems
and the requirements of Borough of Runnemede ordinance.
(2)
Applicability: These requirements are applicable to all commercial
food service establishments, including:
(a)
Those that are undergoing new construction.
(b)
Those that are undergoing interior remodeling to accommodate
expansion or operational or use modifications.
(c)
Those that are undergoing changes of ownership/occupancy.
(d)
Facilities, which may be experiencing difficulty in achieving
compliance with maintenance and/or wastewater discharge limitations.
(3)
Sizing requirements:
(a)
Sizing methods described herein are intended as guidance in
determining grease trap/interceptor sizes that will afford the Borough's
infrastructure a minimum degree of protection against grease and other
obstructing materials. Sizing determinations are based on operational
data provided by business owners or their contractors. In approving
a customer's plumbing or grease interceptor/trap design, the
Borough of Runnemede does not accept liability for the failure of
a system to adequately treat wastewater to achieve effluent quality
requirements specified under this article. It is the responsibility
of the generator and/or contractors to ensure the appropriate level
of treatment necessary for compliance with environmental and wastewater
regulations.
(b)
Minimum acceptable grease trap/interceptor sizing shall be accomplished
as follows:
[2]
The minimum size shall be a twin-compartment, reinforced concrete
grease trap of 1,500 gallons.
[3]
In the circumstance of single-service kitchens with no food preparation (heat/serve only), and which use only paper service items, a minimum fifty-gallon per minute (gpm) flow rated, or one-hundred-pound grease retention, mechanical grease trap may be used. In these instances, the grease trap is to be installed in an area separate from the food handling area, and the trap must be readily accessible for cleaning and maintenance. [See Subsection B(6) below.]
(4)
Grease trap sizing formulas. It is the responsibility of the generator
and his/her contractors to ensure that the wastewater discharged from
his/her facility is in compliance with the Borough's discharge
limitations. For the purpose of plans review, a general assessment
of grease trap/interceptor design and size will be performed using
the following formulas. (These formulas have been demonstrated as
industry standards capable of achieving the Township's discharge
criteria when systems are maintained in proper condition.)

Alternate sizing formulas/proposals. Facilities that propose the
use of alternate sizing techniques and/or procedures that result in
specifications that differ from calculated requirements (or are less
than the minimum recommendation of 1,500 gallons), must submit formulas
and other bases to support proposed grease trap size/installation.
Submission should also provide documentation of ability to meet effluent
quality requirements. This proposal must be signed by a licensed plumbing
contractor or engineer licensed in the State of New Jersey.
(6)
Construction/installation: All permitting, construction, and inspection
activities must be completed in accordance with the Borough of Runnemede's
sewer utility rates, rules, and regulations. Additionally, the following
specifications must be incorporated into grease trap design:
(a)
The grease interceptor/trap shall be constructed with a minimum
of two chambers or shall have a minimum of two tanks in series. If
two-chambered, the dividing wall must extend to within one foot of
the bottom of the tank and within two inches of the top and be securely
fastened to both sides.
(b)
There must be inlet and outlet tees made of Schedule 40 PVC
installed. The inlet tee should extend down approximately 1/3 of the
depth of the trap from the top, and the outlet tee should be located
12 to 18 inches off of the bottom of the trap.
(c)
Grease traps are to be installed at a minimum distance of 10
feet from sinks and dishwashers to allow for adequate cooling of wastewater.
Water temperatures must be less than 140° F. prior to entering
grease trap.
(d)
All grease-bearing waste streams should be routed through an
appropriate grease trap/inceptor, including three-compartment sinks,
pot/pan sinks, soup kettles, hand-washing sinks, dishwashers, mop
sinks and floor drains.
(e)
All exterior or recessed grease traps and interceptors are to
be installed with an effluent sampling well. Sample wells will have
a fifteen-inch-diameter access cover and a minimum four-inch drop
from inlet to outlet piping through the sampling well. Mechanical
grease traps and interceptors that are installed above ground must
be equipped with an influent flow regulator and an effluent valve
assembly that allows for sample collection.
(7)
Customer (generator) responsibilities:
(a)
It is the responsibility of the customer (waste generator) to
ensure compliance with the Borough of Runnemede's discharge limitations.
(b)
Hazardous wastes, such as acids, strong cleaners, pesticides,
herbicides, paint, solvents, or gasoline should not be disposed of
where they would go through grease or grit traps. If commercial dishwashers
are discharged through a grease interceptor/trap, care must be taken
in system design. Dishwashers use detergents and elevated water temperatures
that will melt grease. If the interceptor/trap is either too small
or too close to the commercial dishwasher, grease may pass through
the interceptor/trap and into the collection system.
(c)
Generators are responsible for maintaining grease traps in continuous
proper working condition. Further, generators are responsible for
inspecting, repairing, replacing, or installing apparatus and equipment
as necessary to ensure proper operation and function of grease traps
and compliance with discharge limitations at all times.
(d)
The generator must have a grease trap/grease interceptor service
contract (for pumping, cleaning, and inspection) by the Borough of
Runnemede permitted waste hauler, at a minimum frequency of every
90 days to ensure proper function. The trap shall be maintained more
frequently if needed to meet the Borough's discharge criteria.
Records of maintenance are required to be maintained on site for five
years. (Ninety-day maintenance frequency assumes proper sizing and
installation consistent with this guidance.)
(e)
Enzymes, solvents, and emulsifiers are not permitted, as they
will only change the form of grease, allowing it to be carried out
of the trap with the wastewater and deposited in the Borough of Runnemede
infrastructure. Biological treatment systems must be preapproved by
the Borough of Runnemede. These systems will not alleviate the necessity
for inspection and proper maintenance.
A.
Any person responsible for discharges requiring a grease interceptor/trap
shall, at his own expense and as required by the Borough, provide
plans and specifications for equipment and facilities of a design
type and design capacity approved by the Borough Engineer. The grease
interceptor/trap must be in compliance with the current applicable
plumbing codes, United States Environmental Protection Agency Design
Manual for Onsite Wastewater Treatment and Disposal Systems, and the
requirements of Borough of Runnemede ordinance. The person shall locate
the interceptor/trap in a manner that provides easy accessibility
for cleaning and inspection and maintain the interceptor/trap in effective
operating condition. The Borough of Runnemede Engineer shall inspect
the interceptor/trap during construction and upon completion.
B.
Construction of items listed herein in accordance herewith or in
accordance with the Borough's specifications shall not constitute
a defense to unlawful discharge and shall not limit the generator's
liability for any surcharge stated in this article.
C.
If the Borough of Runnemede determines that there is a need for installation
or upgrading of sample ports or grease interceptors/traps on an existing
establishment, the Borough of Runnemede may order the installation
or upgrading of such interceptors/traps on that existing establishment.
(1)
If the Borough of Runnemede orders such installation, then the Borough
of Runnemede shall serve notice of such order upon the grease generator.
(2)
Within 10 days of receipt of such order, the grease generator may
demand a hearing to review such order, in which case the Borough of
Runnemede, shall schedule a hearing to review such order within 30
days of receiving the demand for review from the grease or grit generator.
If a hearing to review the order is scheduled, the Borough of Runnemede
shall serve notice of the hearing to review such order upon the grease
generator at least 10 days before the date of such hearing.
(3)
The hearing shall be conducted before the Borough Administrator,
if the Borough is the ordering entity.
(4)
At the hearing to review the order, the grease generator may present
evidence and the Borough of Runnemede or its designee, may make new
findings and issue new orders concerning the subject of the original
hearing. After receiving notice of the order to install or upgrade
ports or interceptors/traps on an existing establishment, it shall
be unlawful for a grease generator to allow or cause any discharge
into the sanitary sewer not in compliance with such order.
D.
Where the process wastewaters are generated in only part of the facility,
the process wastewaters may, at the option of the Borough of Runnemede
and/or the discharge into a grease interceptor/trap servicing only
those areas that provide a suitable sampling port.
E.
The Borough of Runnemede may waive the requirement for a grease interceptor/trap,
provided that the grease generator can verify that only domestic sewage
is being discharged, with no floor drains or process water. The Borough
of Runnemede may require testing by the user in connection with this
request, with all costs for this testing being at the user's
expense.
A.
Except for under-the-sink grease interceptors/traps, each interceptor/trap
shall be located outside of a building or structure in an area accessible
for service, and so installed and connected that it shall be at all
times easily accessible for inspection, and for cleaning and removal
of the intercepted waste. Inlet flow-control inspection ports, interceptor/trap
inspection ports, and effluent monitoring ports shall be in areas
where vehicles may not temporarily block access to inspection. The
use of ladders or the removal of bulky equipment or stored materials
in order to inspect inlet flow-control devices, inspect or service
interceptors/traps, or sample interceptor/trap effluent shall constitute
a violation of accessibility. Inspection ports and monitoring ports
shall be located so as to allow inspectors quick and easy access to
the inlet flow-control device, each compartment of the interceptor/trap,
and the effluent from the interceptor/trap. An interceptor/trap shall
not be installed in any part of a building where food is handled.
The location of all interceptors/traps, inspection ports, and monitoring
ports shall meet the approval of the Borough of Runnemede and shall
be shown on the approved building plans.
B.
An inspection port shall be provided for the flow-control device
regulating flow into the interceptor/trap.
C.
A one-piece removable metal plate covering the entire interceptor/trap
shall be preferred as an interceptor/trap inspection port, though
at the discretion of the Borough of Runnemede, standard manhole ports
may be installed over each divider in the interceptor/trap, but in
either case all parts of the interceptor/trap shall be easily accessible
for cleaning and visual inspection.
D.
A monitoring port shall be provided for ease in sampling the treated
effluent from the interceptor/trap and shall be as close as possible
to the connection with the Borough infrastructure within the bounds
of the facility property. The port shall be installed according to
the specifications of the Borough of Runnemede. The port shall be
installed and maintained at the user's expense. A generator shall
properly place, monitor, and maintain the monitoring port so that
wastewater samples taken from the monitoring port are representative
of wastewater leaving the interceptor/trap. It shall be unlawful for
a grease generator to divert sewage around a monitoring point.
A.
In the event that an outside grease interceptor/trap is not practicable,
an under-the-sink grease interceptor/trap may be installed subject
to the approval of the Borough of Runnemede and the Camden County
Health Department. In addition to the regular requirements of grease
interceptors/traps, under-the-sink grease interceptors/traps are subject
to the additional requirements.
B.
General requirements.
(1)
The location of such interceptors/traps shall be in as close proximity
to the source of wastewater as physically possible.
(2)
The lid shall be secured to the body with a single bolt. No wing
nuts or screws shall be permitted.
(3)
Baffle systems and all other internal pieces shall be removable to
facilitate cleaning and replacement, but must be in place at all other
times.
(4)
The lid shall cover the deep seal trap. The deep seal trap shall
be constructed so as to eliminate the possibility of sewer gas entering
the kitchen area.
(5)
The interceptors/traps shall be constructed with bottom supports
so that the body of the interceptor/trap does not corrode by coming
into contact with the floor.
(6)
The interceptor/trap shall be coated with a powder-coated, electrostatically
applied cathodic epoxy coating so as to be resistant to corrosion.
(7)
The interceptor/trap shall be equipped with a flow-control fitting.
C.
Installation requirements.
(1)
The interceptor/trap may be set on the floor, partially recessed
in the floor with top flush with the floor, or fully recessed below
the floor to suit piping and structural conditions, as acceptable
by the inspection of the Borough of Runnemede Engineer.
(2)
There shall be sufficient clearance for the removal of the interceptor/trap
cover for cleaning.
(3)
Unless specifically approved by the Borough Engineer, runs of pipe
exceeding 25 feet between fixture and interceptor/trap shall not be
permitted.
(4)
The interceptor/trap shall not be installed in a waste line from
a garbage grinder. Any garbage grinder waste shall bypass the interceptor/trap.
(5)
A suitable flow-control fitting shall be installed ahead of the interceptor/trap
in the waste line beyond the fixture and as close as possible to the
underside of the lowest fixture. When wastes of two or more sinks
or fixtures are combined to be used by one interceptor/trap, a single
flow-control fitting shall be used.
(6)
Air intake for flow-control either shall terminate under-the-sink
drain board as high as possible to prevent overflow, or shall terminate
in a return bend at the same height and on the outside of the building.
(7)
To retain water and prevent siphoning, all interceptors/traps shall
have a vented waste, sized in accordance with the Plumbing Code.
(8)
With the approval of the Borough of Runnemede and the Camden County
Health Department, one interceptor/trap may be used to serve multiple
fixtures if the fixtures are located close together and the interceptor/trap
is sized to meet the combined flow of all the fixtures.
D.
Maintenance requirements.
(1)
Interceptors/traps shall be serviced at least every week by a permitted
vacuum truck cleaning service. After accumulated grease and waste
have been removed, the interceptor/trap shall be thoroughly inspected
to make certain that inlet, outlet, and air relief ports are clear
of obstructions.
(2)
Grease and other waste removed from the interceptor/trap shall not
be introduced into any drain, sewer, or natural body of water. The
waste shall be placed in proper containers for proper disposal. It
shall not be mixed with "edible" grease. Grease and waste removed
from an interceptor/trap shall not be disposed of in such a matter
so as to become food for animals or humans.
(3)
The grease generator shall maintain adequate documentation that the
interceptor/trap is appropriately cleaned and inspected.
Grease interceptor/trap waste generators shall meet all applicable
requirements regarding the accumulation, generation, and disposal
of waste as found in this article.
A.
Interceptor/trap maintenance service contract.
(1)
All grease generators having interceptors/traps shall perform all
business transactions relating to interceptor/trap pumping, cleaning,
and servicing, and to liquid waste collection, transportation and/or
disposal on a contractual basis via a written contract having a duration
of at least one year, and provide copies of all such contracts to
the Borough of Runnemede. Any modifications or changes to the contract
must be submitted to the Borough of Runnemede within 10 working days
of the change or modification. It is a violation for a grease generator
to discharge through an interceptor/trap without a service contract.
(2)
A contract shall at a minimum:
(a)
From the customer:
[1]
Contain the customer name, address and telephone number, and
the name, address, and telephone number of the facility to be serviced
if different.
[2]
Contain the name of a primary and secondary contact person for
the facility.
[3]
Contain the grease interceptor/trap permit number of the facility.
[4]
Indicate the size of each interceptor/trap.
[5]

of the facility, whichever is less.
B.
Required pumping frequency.
(1)
Unless otherwise specified by the Borough of Runnemede, each interceptor/trap
in active use shall be cleaned at least once every quarter or more
frequently as needed to prevent carry-over of grease into the Borough
of Runnemede infrastructure, unless it can be demonstrated to the
Borough of Runnemede that the pumping frequency can be performed at
greater intervals. Either the Borough of Runnemede may specify cleaning
more frequently when quarterly pumping is shown to be inadequate.
Additional pumping may be required during time periods where increased
loading is anticipated. Any grease generator desiring a schedule less
frequent than quarterly shall submit a request to the Borough of Runnemede
along with testing and copies of the cleaning records for the last
four interceptor/trap cleanings, including measurements of the thickness
of the surface scum/grease layer.
(2)
At any time if an inspection finds the interceptor/trap to be full,
immediate steps shall be taken by the grease generator to pump out
and clean it as soon as is practicable. The inspector shall make an
evaluation of the advisability of allowing discharge to continue,
and may at his or her discretion order an immediate cessation of all
discharge from the facility. In any case, the wastewater discharge
permit of the facility may be amended so as to compel more frequent
pumping and cleaning of the interceptor/trap.
C.
All interceptors/traps shall be maintained by the grease generator
at the grease generator's expense.
D.
Requirement for increased pumpage or servicing.
(1)
If the Borough of Runnemede finds that a change in pumpage or servicing
of an interceptor/trap is necessary for an establishment to meet the
discharge limits stated in this article, the Borough of Runnemede
may order a change in pumpage or servicing of an interceptor/trap.
(2)
If the Borough of Runnemede orders a change in the pumpage or servicing,
then the Borough of Runnemede shall serve notice of such order upon
the generator.
(3)
Within 10 days of receipt of such order, the generator may demand
a hearing to review such order, in which case the Borough of Runnemede
shall schedule a hearing to review such order within 30 days of receiving
the demand for review from the generator.
(4)
If a hearing to review the order is scheduled, the Borough of Runnemede
shall serve notice of the hearing to review such order at least 10
days before the date of such hearing. At the hearing to review the
order, the generator may present evidence, and the Borough of Runnemede
may make new findings and issue new orders concerning the subject
of the original hearing.
(5)
After receiving notice of an order by the Borough of Runnemede to
change the frequency and/or methods of pumpage or servicing, it shall
be unlawful for a generator to allow or cause any discharge into the
sanitary sewer not in compliance with such order.
E.
Interceptor/trap maintenance log.
(1)
Every generator having an interceptor/trap shall maintain an interceptor/trap
maintenance log indicating each pumping for the previous 12 months.
This log shall include the date, time, amount pumped, hauler and disposal
site, and shall be kept in a conspicuous location on the premises
of the facility for inspection. Food service establishments shall
keep the log posted with the Borough of Runnemede. Said log shall
be made immediately available to any authorized inspector.
(2)
The information required in the maintenance log must be submitted
to the Borough of Runnemede annually. The reporting period shall be
January 1 through December 31 of each year. The report shall be submitted
within 30 days after the end of the reporting period to the Borough
of Runnemede.
F.
Cleaning procedures.
(1)
The owner or an employee of the facility shall supervise the interceptor/trap
cleaning and shall be physically present and observe the entire cleaning
operation.
(2)
A generator shall cause the liquid waste hauler, transporter, or
any other person cleaning or servicing an interceptor/trap to completely
evacuate all contents, including floating materials, wastewater, and
bottom sludges and solids, of all grease and/or grit interceptors/traps
and other interceptors/traps during servicing.
(a)
Skimming the surface layer of waste material, partial cleaning
of the interceptor/trap or use of any method that does not remove
the entire contents of the collection device is prohibited. The suction
of the floating materials shall be done prior to removal of other
contents. After complete evacuation, the walls, top, and bottom of
the interceptor/trap shall then be thoroughly scraped and the residue
removed. The interceptor/trap shall then be steam cleaned and the
residue removed.
(b)
Upon completion of the servicing, the manager of the facility
shall make an inspection of the interior of the interceptor/trap and
then personally sign the trip ticket. The manager shall make an appropriate
entry in the facility interceptor/trap maintenance log and post the
generator section of the trip ticket in a conspicuous place with the
log on the premises. Food service establishments shall keep all trip
tickets posted with the Borough of Runnemede. Said trip tickets and
maintenance logs shall be made immediately available to any authorized
inspector.
(3)
It shall be unlawful for a generator to allow the discharge of liquid,
semisolids, or solids back into an interceptor/trap during and/or
after servicing. Decanting or discharging of removed waste back into
the interceptor/trap from which the waste was removed or any other
interceptor/trap, for the purpose of reducing the volume to be disposed,
is prohibited.
(4)
Each interceptor/trap pumped shall be fully evacuated unless the
interceptor/trap volume is greater than the tank capacity on the vacuum
truck in which case the transporter shall arrange for additional transportation
capacity so that the interceptor/trap is fully evacuated within a
twenty-four-hour period following the transporter's inability
to fully evacuate the interceptor/trap.
G.
Disposal of interceptor/trap pumpage.
(1)
All waste removed from each interceptor/trap shall be disposed of
at a facility permitted and authorized to receive such waste in accordance
with all applicable federal, state, and local regulations. In no way
shall the pumpage be returned to any private or public portion of
the Borough infrastructure, without prior written approval from the
Borough of Runnemede.
(2)
Additionally, grease removed from an interceptor/trap shall not be
recycled so as to become a food product or part of a food product
for animal or human consumption.
H.
Vacuum truck cleaning service. It shall be unlawful for a grease
or grit generator to allow grease or grit interceptor/trap waste to
be removed from his premises by a transporter who does not have all
applicable federal, state, or local permits or registrations.
All interceptor/trap waste generators shall, at a frequency
and time determined by the Borough of Runnemede, but in no case less
than once per year, submit to the Borough of Runnemede:
A.
Copies of all manifests made by liquid waste transporters servicing
their grease interceptor/trap during the reporting period;
B.
A copy of the interceptor/trap maintenance log;
C.
A copy of the interceptor/trap service contract; and
D.
Any other information required by the grease interceptor/trap permit,
including analysis of the discharge to the Borough of Runnemede infrastructure
of such pollutants as the Borough of Runnemede may require.
A.
Use of grease interceptor/trap treatment products, including bacteria,
designed to digest grease, is specifically prohibited without prior
written consent of the Camden County Utilities Authority.
B.
Acceptance of such products for use may be considered only where
a valid screening test, showing the product's ability to treat
the waste and to produce an influent in compliance with this article,
has been performed in accordance with methods outlined by the Borough
of Runnemede.
C.
Screening tests for such grease interceptor/trap treatment products
shall be designed by the Borough of Runnemede with authority from
the Camden County Utilities Authority.
D.
The results of screening tests may be subject to technical review
by either Borough of Runnemede or the Camden County Utilities Authority.
E.
All costs of screening tests shall be borne by the facility whether
or not the product is accepted for use.

must be disclosed to the Borough of Runnemede and the Camden County
Utilities Authority.
H.
The Camden County Utilities Authority may revoke permission to use
such products where the effluent from the interceptor/trap or basin
in which the product is used fails to meet the requirements of the
article.
Any person wishing to make use of a mobile treatment process
or of an on-site process to clean or service grease interceptors/traps
or grit interceptors must provide written approval from the Camden
County Utilities Authority and the State of New Jersey prior to any
treatment being performed. The process shall also be demonstrated
to the satisfaction of the Borough of Runnemede. Included with the
demonstration shall be a written explanation of the treatment process.
Any costs to the Borough of Runnemede associated with the demonstration,
such as but not limited to sampling and analysis, and engineering
review shall be recovered. Complete descriptions of the chemical composition
of all products must be disclosed to the Borough of Runnemede.
A.
When a facility with a grease interceptor/trap closes for business
and is subsequently:
(2)
Remodeled such that the grease interceptor/trap will not be used,
then the grease interceptor/trap may be left in place. However, the
grease interceptor or trap shall have all effluent pumped out, the
trap cleaned thoroughly, and the grease interceptor or interceptors
or traps left dry and empty and be replumbed as to bypass the existing
grease interceptor or interceptors or traps, either by straight through
or by bypassing methods, while leaving the empty trap and in place
for possible future utilization by another business.
(3)
Replaced with a type of business that will not utilize the grease
interceptor/trap, then that business may have any existing grease
interceptor/trap or interceptors or traps:
(a)
Physically removed; or
(b)
Replumbed as to bypass the existing grease interceptor/trap
or interceptors or traps, either by straight through or by bypassing
methods, while leaving the empty trap and in place for possible future
utilization by another business; or
(c)
Replumbed with a straight line plumbed from the inlet to the
outlet, and the remainder of the grease interceptor or interceptors
or traps filled with soil or sand.
B.
In all instances, the owner of the premises shall appropriately inform
the Borough of Runnemede and perform the closure at such a time so
as to permit an inspector to be physically present during the removal
or filling of the interceptor/trap.
A.
Access to premises. It shall be unlawful for a grease generator to
refuse to allow inspectors to enter their premises during reasonable
hours to determine whether the grease generator is complying with
all of the requirements of this article. A grease generator shall
allow the inspectors access to all parts of the premises for purposes
of inspection, sampling, records examination and copying, and the
performance of additional duties. Arrangements for the immediate access
of the Borough of Runnemede or its designate representative shall
have been made ahead of time, and such failure to make adequate arrangements
shall not be considered a legitimate reason to refuse admittance of
the Borough of Runnemede.
B.
Private premises. In cases where a facility includes private living
quarters, the right of access shall extend to all common areas, and
any other area or areas a facility employee, including the manager
and/or owner, may enter without expressed permission of the residents
of such a facility.
C.
Search warrants. If the Borough of Runnemede has been refused access
to a building, structure, or property, or any part thereof, and is
able to demonstrate probable cause to believe that there may be a
violation of this article, or that there is a need to inspect and/or
sample as part of a routine inspection and sampling program of the
Borough designed to verify compliance with this article or any permit
or order issued hereunder, or to protect the overall public health,
safety and welfare of the community, then the Borough of Runnemede
may seek issuance of a search warrant from any court of competent
jurisdiction.
A.

postage prepaid, into a mail facility serviced by the United States
Postal Service, the date of receipt shall govern.
The Borough of Runnemede may seek reimbursement of all fees
incurred as a result of inspection, testing and monitoring.
A.
It is unlawful for any grease generator to discharge into the Borough
infrastructure in any manner that is in violation of this article,
or of any condition set forth in this article. Additionally, a person
commits an offense if the person causes or permits the plugging or
blocking of or otherwise interferes with or permits the interference
of a grease interceptor/trap or the Borough infrastructure, including
alteration or removal of any flow-constricting devices so as to cause
flow to rise above the design capacity of the interceptor/trap.
B.
No person, and/or facility shall discharge grease in excess of 100
milligrams per liter to the Borough infrastructure. If such discharge
occurs, the person or facility shall be considered in violation of
this article and subject to the remedies described herein. This includes
nonpermitted facilities.
C.
The Borough of Runnemede may suspend water or sewer service when
such suspension is necessary, in the opinion of the Borough of Runnemede
in order to stop an actual or threatened discharge which:
(1)
Presents or may present an imminent or substantial endangerment to
the health or welfare of persons or the environment;
(2)
Causes stoppages or excessive maintenance to be performed to prevent
stoppages in the sanitary sewer collection system;
(3)
Causes interference to the Borough infrastructure; or
(4)
Causes the Borough of Runnemede to violate any condition of its NPDES
or NJPDES permit.
D.
Any person notified of a suspension of the water or sewer service
shall immediately stop or eliminate the discharge. In the event of
a failure of the person to comply voluntarily with the suspension
order, the Borough shall take such steps as deemed necessary, including
immediate termination of water or sewer service, to prevent or minimize
damage to the Borough system or sewer connection or endangerment to
any individuals. The Borough of Runnemede shall reinstate the water
or sewer service when such conditions causing the suspension have
passed or been eliminated. A detailed written statement submitted
by the grease generator describing the cause(s) of the harmful discharge
and the measure(s) taken to prevent any future occurrence shall be
submitted to the Borough of Runnemede within 15 days of the date of
occurrence.
E.
In addition to prohibiting certain conduct by natural persons, it
is the intent of this article to hold a corporation, association,
LLC, LLP or PS legally responsible for prohibited conduct performed
by an agent acting in behalf of a corporation or association and within
the scope of his office or employment.
F.
Any person, operator, or owner who shall violate any provision of
this article, or who shall fail to comply with any provision hereof,
shall be subject to the penalties for each violation, and each day
a violation continues shall constitute a separate offense and shall
be punished accordingly.
(1)
In accordance with the provisions of N.J.S.A. 40:49-5 the maximum

an appropriate penalty for each and every violation. Any lesser penalty,
including a nominal penalty or no penalty at all, may be appropriate
for a particular case or violation.
G.
A grease generator is liable to the Borough of Runnemede for any
expense, loss, or damage incurred by the Borough of Runnemede for
reason of appropriate cleanup and proper disposal of said waste materials.
Additionally, an administrative fee equal to 1/2 of assessed cleanup
costs shall be levied by the Borough against the guilty party.
The Borough of Runnemede is authorized to promulgate such rules
and regulations as shall be reasonable and necessary to carry out
the provisions of this article according to its terms and intent.
