indicates a different intention, the following terms shall, for the
purpose of this article, have the meanings indicated in this section:
An interceptor that does not allow a discharge of oil and
grease in excess of 100 milligrams per liter (mg/l) concentrations,
or otherwise has not been found by the Borough of Gibbsboro to be
contributing grease in quantities sufficient to cause POTW line stoppages
or necessitate increased maintenance on the POTW in order to keep
line stoppages from occurring. Substances which may solidify or become
viscous at temperatures between 32° F. and 150° F. (0°
C. and 65° C.) are also prohibited.
The Borough of Gibbsboro. Where appropriate, the term may
also be used as a designation for other duly authorized officials,
including authorized contractors, acting as representatives of said
Borough.

waste at a disposal facility, and who is authorized to sign a trip
ticket, regardless of actual title.
A permitted site or part of a site at which grease interceptor
waste, grit interceptor waste, or seepage is processed, treated and/or
intentionally placed into or on any land in a manner compliant with
all applicable federal, state, and local regulations, and at which
site said waste will remain after closure.
Any substance or substances which, when added or placed into
a grease trap or grease interceptor, will form an oily substance to
a milky fluid in which the fat globules are in a very finely divided
state and are held in suspension, giving it the semblance of a solution.
Any building, structure, facility, or installation from which
there is or may be a discharge of pollutants, the construction of
which started before the adoption of this article.
Substances that are primarily fatty acid esters of the alcohol
glycerol, also called acylglycerols, neutral fats, natural fats, or
glycerides. They are the major components of depot, or storage, fats
in plant and animal cells, especially in the adipose (or fat) cells
of vertebrates. This term may include any synthesized substance of
a like nature.
Areas predominantly found in shopping centers or amusement
parks and festivals where several food preparation establishments
having different owners may be sharing seating space and/or plumbing
facilities.
Any facility that cuts, cooks, bakes, prepares or serves
food, or which disposes of food-related wastes and/or which has a
local, state, and/or federal food service permit.

materials into smaller portions for discharge into the POTW.
A facility that causes, creates, generates, stores, or otherwise
produces waste from on-site process operations, whether domestically
or commercially generated, or as a by-product of some domestic or
nondomestic activity. The generator is responsible for assuring that
the produced waste is disposed of in accordance with all federal,
state and local disposal regulations.
Fats, waxes, free fatty acids, calcium and magnesium soaps,
mineral oils and certain other nonfatty material from animal or vegetable
sources, or from hydrocarbons of petroleum origins, commonly found
in wastewater from food preparation and food service. Grease may originate
from, but not be limited to, discharges from scullery sinks, pot and
pan sinks, dishwashing machines, soup kettles and floor drains located
in areas where grease-containing materials may exist.
A watertight receptacle utilized by commercial or industrial
generators of liquid waste to intercept, collect, and restrict, the
passage of grease and food particles into the POTW to which the receptacle
is directly or indirectly connected, and to separate and retain grease
and food particles from the wastewater discharged by a facility.
Any grease, food particles, or organic or inorganic solid
or semisolid waste collected and intercepted by a grease interceptor,
usually in layers of floatable, suspended, and settleable substances,
which are ultimately removed from a grease interceptor for proper
disposal. All layers must be removed for disposal.

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 A(2) or (3) 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 material, but particularly biological lipids and mineral
hydrocarbons, recovered as a substance soluble in an organic extracting
solvent using an appropriate analytical method approved under 40 CFR
136. It also includes other material extracted by the solvent from
an acidified sample and not volatilized during the extraction procedure.
Publicly owned treatment works.
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 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 waste, seepage, and
other liquid wastes enabling legal and proper disposal of hauled grit
interceptor waste, grease interceptor 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 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 POTW.
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.
A.
Waste, which contains grease, shall be discharged
into the POTW system only under the conditions of this article. The
following facilities shall discharge all waste from sinks, dishwashers,
drains, and any other fixtures through which grease may be discharged,
into an adequately sized, properly maintained and functioning grease
interceptor before the discharge enters the POTW, as well as providing
a grease interceptor inlet flow-control device inspection port and
a grease interceptor 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 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 Gibbsboro, will, alone or in
concert with other substances from the discharges of other facilities,
have a reasonable chance to impede or stop the flow in the POTW.
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.
C.
Interceptors shall not be required for single-family
residences, duplexes, triplexes, quadplexes, or apartment complexes,
unless the Borough first determines there are discharges from the
property that will damage the POTW. 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 in the POTW, the Borough
of Gibbsboro may require the installation of a sufficiently sized
grease interceptor 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 § 311-25C above) shall be required to install an approved, adequately sized, and properly operated and maintained grease interceptor when any of the following conditions exist:
(1)
It is found by the Borough of Gibbsboro to be contributing
grease in quantities sufficient to cause sanitary sewer line stoppages
or necessitate increased maintenance on the sanitary sewer collection
system (POTW) in order to keep main line stoppages from occurring.
(2)
Its interceptor allows a discharge of oil or grease
in excess of 100 mg/l.
B.
Existing facilities required by this article or other
applicable ordinance to maintain a grease interceptor equipped with
an undersized grease interceptor shall, within 12 months of the effective
date of this article, install an adequately sized grease interceptor
in accordance with the specifications of this article.
C.
Existing facilities required by this article or other
applicable ordinances to maintain a grease interceptor not equipped
with a grease interceptor shall, within 12 months of the effective
date of this article, install an adequately sized grease interceptor
in accordance with the specifications of this article.
D.
New facilities required by this article or other applicable
ordinances to maintain a grease interceptor shall install such a unit
prior to commencement of discharge to the POTW.
E.
Any requests for extensions to installation dates
must be made in writing to the Borough Clerk, 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 Gibbsboro shall determine the date for compliance.
A.
Where oil and grease are a by-product of food preparation
and/or cleanup, reasonable efforts shall be made to separate waste
oil and grease into a separate container for proper disposal. Except
as contained in by-products of food preparation and/or cleanup, waste
oil and grease shall not be discharged to any drains or grease interceptors.
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, or into any drain that leads to the interceptor:
(1)
Emulsifiers, de-emulsifiers, surface active agents,
enzymes, degreasers, or any type of product that will liquefy grease
interceptor wastes;
(2)
Any substance that may cause excessive foaming in
the POTW; or
(3)
Any substance capable of passing the solid or semisolid
contents of the grease interceptor to the POTW.
C.
The influent to interceptors 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.
E.
All waste shall only enter the grease interceptor
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. 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 Gibbsboro:
(1)
Provide an adequately sized grease interceptor. Requirements for grease trap sizing and the design criteria are provided in Subsection B below.
(2)
Locate the interceptor in a manner that provides ready
and easy accessibility for cleaning and inspection.
(3)
Obtain a written interceptor 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 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 Gibbsboro,
service the interceptor 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: Information contained within this document
is based on standard industry practices and guidance found in both
the 1997 International Plumbing Code (IPC) Commentary and the Uniform
Plumbing Code (UPC), Appendix A. Size, type, and location of grease
traps shall be in accordance with the manufacturers instructions and
the requirements of Borough of Gibbsboro 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 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 sanitary sewer system (POTW) 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 design, the Borough 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 Borough's discharge
criteria when systems are maintained in proper condition.)

(5)
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
Plumbing Code. Additionally, the following specifications must be
incorporated into grease trap design:
(a)
The grease interceptor 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 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.
|
Notable exceptions: Drains that receive "clear
waste" only, such as from ice machines, condensate from coils and
drink stations, may be plumbed to the sanitary system without passing
through the grease interceptor with the condition that the receiving
drain is a "hub" type that is a minimum of two inches above the finished
floor.
|
(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 Gibbsboro 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, care must
be taken in system design. Dishwashers use detergents and elevated
water temperatures that will melt grease. If the interceptor is either
too small or too close to the commercial dishwasher, grease may pass
through the interceptor 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 a Borough of Gibbsboro 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 collection
system (POTW). Biological treatment systems must be preapproved by
the Borough of Gibbsboro. These systems will not alleviate the necessity
for inspection and proper maintenance.
A.
Any person responsible for discharges requiring a
grease interceptor 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 must be in compliance with the current applicable
Plumbing Codes. The person shall locate the interceptor in a manner
that provides easy accessibility for cleaning and inspection and maintain
the interceptor in effective operating condition. The Borough Engineer
shall inspect the interceptor 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 Gibbsboro determines that there
is a need for installation or upgrading of sample ports or grease
interceptors on an existing establishment, the Borough of Gibbsboro
may order the installation or upgrading of such interceptors on that
existing establishment. If the Borough of Gibbsboro orders such installation,
then the Borough of Gibbsboro shall serve notice of such order upon
the grease generator. 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 Gibbsboro 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 Gibbsboro shall serve notice of the hearing to review
such order upon the grease generator at least 10 days before the date
of such hearing. At the hearing to review the order, the grease generator
may present evidence, and the Borough of Gibbsboro 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 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 Gibbsboro, discharge into a grease interceptor servicing
only those areas that provide a suitable sampling port.
E.
The Borough of Gibbsboro may waive the requirement
for a grease interceptor, provided that the grease generator can verify
that only domestic sewage is being discharged, with no floor drains
or process water. The Borough of Gibbsboro 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, each
interceptor 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 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, or sample interceptor 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,
and the effluent from the interceptor. An interceptor shall not be
installed in any part of a building where food is handled. The location
of all interceptors, inspection ports, and monitoring ports shall
meet the approval of the Borough of Gibbsboro 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.
C.
A one-piece removable metal plate covering the entire
interceptor shall be preferred as an interceptor inspection port,
though at the discretion of the Borough of Gibbsboro, standard manhole
ports may be installed over each divider in the interceptor, but in
either case all parts of the interceptor 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 and shall be as close as
possible to the connection with the Borough POTW within the bounds
of the facility property. The port shall be installed according to
the specifications of the Borough of Gibbsboro. 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. It shall be unlawful for a
grease generator to divert sewage around a monitoring point into the
POTW.
A.
In the event that an outside grease interceptor is
not practicable, an under-the-sink grease interceptor may be installed
subject to the approval of the Camden County Health Department. In
addition to the regular requirements of grease interceptors, under-the-sink
grease interceptors are subject to the additional requirements.
B.
General requirements.
(1)
The location of such interceptors 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 shall be constructed with bottom
supports so that the body of the interceptor does not corrode by coming
into contact with the floor.
(6)
The interceptor shall be coated with a powder coated
electrostatically applied cathodic epoxy coating so as to be resistant
to corrosion.
(7)
The interceptor shall be equipped with a flow-control
fitting.
C.
Installation requirements.
(1)
The interceptor 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 Engineer.
(2)
There shall be sufficient clearance for the removal
of the interceptor cover for cleaning.
(3)
Unless specifically approved by the Borough Engineer,
runs of pipe exceeding 25 feet between fixture and interceptor shall
not be permitted.
(4)
The interceptor shall not be installed in a waste
line from a garbage grinder. Any garbage grinder waste shall bypass
the interceptor.
(5)
A suitable flow-control fitting shall be installed
ahead of the interceptor 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, a single flow-control fitting shall be used.
(6)
Air intake for flow-control either shall terminate
under-the-sink drainboard 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
shall have a vented waste, sized in accordance with the Plumbing Code.
(8)
With the approval of the Camden County Health Department,
one interceptor may be used to serve multiple fixtures if the fixtures
are located close together and the interceptor is sized to meet the
combined flow of all the fixtures.
D.
Maintenance requirements.
(1)
Interceptors shall be serviced at least every week
by a permitted vacuum truck cleaning service. After accumulated grease
and waste has been removed, the interceptor 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
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 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 is appropriately cleaned and inspected.
A.
Interceptor maintenance service contract.
(1)
All grease generators having interceptors shall perform
all business transactions relating to interceptor 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 Gibbsboro. Any modifications or changes to the contract
must be submitted to the Borough of Gibbsboro within 10 working days
of the change or modification. It is a violation for a grease generator
to discharge through an interceptor 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 permit number
of the facility.
[4]
Indicate the size of each interceptor.
[5]
Indicate the precise and unambiguous location
of the interceptor or interceptors to be serviced, including a diagram
if necessary.
[6]
Indicate the frequency of pumpage required.
[7]
Be signed and dated by an authorized representative
indicating acceptance of the terms of the contract.
(b)
From the vacuum truck cleaning service:
[1]
Contain the vacuum truck company name, address,
and telephone number.
[2]

(c)
Other: contain a statement of the duration of
the contract, to be not less than one year, or for the duration of
the operation of the facility, whichever is less.
B.
Required pumping frequency.
(1)
Unless otherwise specified by the Borough of Gibbsboro,
each interceptor in active use shall be cleaned at least once every
quarter or more frequently as needed to prevent carry over of grease
into the POTW, unless it can be demonstrated to the Borough of Gibbsboro
that the pumping frequency can be performed at greater intervals.
The Borough of Gibbsboro 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 Gibbsboro along with testing
(as required by the Borough of Gibbsboro) and copies of the cleaning
records for the last four interceptor cleanings, including measurements
of the thickness of the surface scum/grease layer.
(2)
At any time if an inspection finds the interceptor
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.
C.
All interceptors shall be maintained by the grease
generator at the grease generator's expense.
D.
Requirement for increased pumpage or servicing. If
the Borough of Gibbsboro finds that a change in pumpage or servicing
of an interceptor is necessary for an establishment to meet the discharge
limits stated in this article, the Borough of Gibbsboro may order
a change in pumpage or servicing of an interceptor. If the Borough
of Gibbsboro orders a change in the pumpage or servicing, then the
Borough of Gibbsboro shall serve notice of such order upon the generator.
Within 10 days of receipt of such order, the generator may demand
a hearing to review such order, in which case the Borough of Gibbsboro
shall schedule a hearing to review such order within 30 days of receiving
the demand for review from the generator. If a hearing to review the
order is scheduled, the Borough of Gibbsboro 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 Gibbsboro may make new findings
and issue new orders concerning the subject of the original hearing.
After receiving notice of an order by the Borough of Gibbsboro 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 (POTW) not in compliance with such order.
E.
Interceptor maintenance log.
(1)
Every generator having an interceptor shall maintain
an interceptor 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 Gibbsboro. Said log
shall be made immediately available to any authorized Borough inspector.
(2)
The information required in the maintenance log must
be submitted to the Borough of Gibbsboro 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 Gibbsboro.
F.
Cleaning procedures.
(1)
The owner or an employee of the facility shall supervise
the interceptor 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 to completely
evacuate all contents, including floating materials, wastewater, and
bottom sludges and solids, of all grease and/or grit interceptors
and other interceptors during servicing. Skimming the surface layer
of waste material, partial cleaning of the interceptor 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 shall then be thoroughly
scraped and the residue removed. The interceptor shall then be steam
cleaned and the residue removed. Upon completion of the servicing,
the manager of the facility shall make an inspection of the interior
of the interceptor and then personally sign the trip ticket. The manager
shall make an appropriate entry in the facility interceptor 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 Gibbsboro. Said trip
tickets and maintenance logs shall be made immediately available to
any authorized Borough inspector.
(3)
It shall be unlawful for a generator to allow, the
discharge of liquid, semisolids, or solids back into an interceptor
during and/or after servicing. Decanting or discharging of removed
waste back into the interceptor from which the waste was removed or
any other interceptor, for the purpose of reducing the volume to be
disposed, is prohibited.
(4)
Each interceptor pumped shall be fully evacuated unless
the interceptor 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 is fully evacuated within a twenty-four-hour
period following the transporter's inability to fully evacuate the
interceptor.
G.
Disposal of interceptor pumpage. All waste removed
from each interceptor 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 POTW, without
prior written approval from the Borough of Gibbsboro, nor may it be
returned to any portion of the POTW not specifically designated by
the Wastewater Collections/Treatment Superintendent. Additionally,
grease removed from an interceptor 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
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 waste generators shall, at a
frequency and time determined by the Borough of Gibbsboro, but in
no case less than once per year, submit to the Borough of Gibbsboro:
A.
Use of grease interceptor treatment products, including
bacteria, designed to digest grease, is specifically prohibited without
prior written consent of the Camden County Municipal Utilities Authority
(CCMUA).
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 Gibbsboro.
C.
Screening tests for such grease interceptor treatment
products shall be designed by the CCMUA.
D.
The results of screening tests shall be subject to
technical review by the CCMUA.
E.
All costs of screening tests shall be borne by the
facility whether or not the product is accepted for use.
F.
If a product is accepted for use, each facility shall
obtain written permission from the Borough of Gibbsboro to use the
product.
G.
Complete descriptions of the chemical composition
of all products must be disclosed to the CCMUA.
H.
The CCMUA may revoke permission to use such products
where the effluent from the interceptor 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
or grit interceptors must provide written approval from the CCMUA
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 Gibbsboro. Included with the demonstration shall be a written
explanation of the treatment process. Any costs to the Borough 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 Gibbsboro.
A.
When a facility with a grease interceptor closes for
business and is subsequently:
(2)
Remodeled such that the grease interceptor will not
be used, then the grease interceptor or interceptors or traps may
be left in place. However, the grease interceptor or interceptors
or traps 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, then that business may have any existing grease
interceptor or interceptors or traps:
(a)
Physically removed; or
(b)
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; 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 Gibbsboro 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.
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 Gibbsboro 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 Gibbsboro.
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 Gibbsboro 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 Gibbsboro may seek issuance of a search warrant from any court
of competent jurisdiction
A.
Information and data on a grease generator, or any other entity, obtained from reports, surveys, grease interceptor permits, and monitoring programs, and from the Borough of Gibbsboro's inspection and sampling activities, and any other information submitted to the Borough of Gibbsboro pursuant to this article, shall be available to the public without restriction, at least to the extent provided by this Chapter 311.
B.
Any grease generator, or any other entity, may claim
any such information to be confidential and proprietary.
All written reports, applications, and any other
such material required by those regulated under this article will
be deemed to have been submitted on the date postmarked. For material,
which is not mailed, postage prepaid, into a mail facility serviced
by the United States Postal Service, the date of receipt shall govern.
The Borough 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 POTW 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 or the POTW, including alteration or removal
of any flow-constricting devices so as to cause flow to rise above
the design capacity of the interceptor.
B.
No person, and/or facility shall discharge grease
in excess of 100 mg/l to the POTW. 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 may suspend water or sewer service when
such suspension is necessary, in the opinion of the Borough of Gibbsboro,
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 POTW; or
(4)
Causes the Borough 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 POTW system or sewer connection or endangerment
to any individuals. The Borough 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 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 in Chapter 1, Article I, General Penalty, for each violation, and each day a violation continues shall constitute a separate offense and shall be punished accordingly.
G.
A grease generator is liable to the Borough for any
expense, loss, or damage incurred by the Borough 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 Gibbsboro is authorized to promulgate
such rules and regulations as shall be reasonable and necessary to
carry out the provisions of this chapter according to its terms and
intent.
