Borough of Gibbsboro, NJ Disposal of Grease Interceptor Waste

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

UNDER-THE-SINK GREASE INTERCEPTOR

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.

§ 311-25 Applicability.

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:

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.

All shopping centers that have food processing facilities.

All food courts.

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.

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.

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.

§ 311-26 Compliance date.

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:

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.

Its interceptor allows a discharge of oil or grease in excess of 100 mg/l.

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.

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.

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.

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.

§ 311-27 Discharge criteria.

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.

None of the following agents shall be placed directly into a grease interceptor, or into any drain that leads to the interceptor:

Emulsifiers, de-emulsifiers, surface active agents, enzymes, degreasers, or any type of product that will liquefy grease interceptor wastes;

Any substance that may cause excessive foaming in the POTW; or

Any substance capable of passing the solid or semisolid contents of the grease interceptor to the POTW.

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.

Toilets, urinals, and other similar fixtures shall not discharge through a grease interceptor.

All waste shall only enter the grease interceptor through the inlet flow-control device, then the inlet pipe.

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.

§ 311-28 Requirements for grease interceptors.

All commercial and industrial facilities dealing with grease shall, at the permittees' expense and as required by the Borough of Gibbsboro:

Provide an adequately sized grease interceptor. Requirements for grease trap sizing and the design criteria are provided in Subsection B below.

Locate the interceptor in a manner that provides ready and easy accessibility for cleaning and inspection.

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.

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.

Allow demand inspection of the facility and of records by inspectors during reasonable hours.

Requirements for grease trap sizing and design criteria.

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.

Applicability: These requirements are applicable to all commercial food service establishments, including:

Those that are undergoing new construction.

Those that are undergoing interior remodeling to accommodate expansion or operational modifications.

Those that are undergoing changes of ownership/occupancy.

Facilities, which may be experiencing difficulty in achieving compliance with maintenance and/or wastewater discharge limitations.

Sizing requirements:

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.

Minimum acceptable grease trap/interceptor sizing shall be accomplished as follows:

Sizing according to formulas found in Subsection B(4) below.

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.]

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.)

Method 1 Uniform Plumbing Code Appendix A
Number of meals x waste flow x retention x storage = size requirement
Per peak hour (1) rate (2) time (3) factor (4) liquid capacity
Factors:
	1)	Number of meals served at peak operating hour (seating capacity) x peak factor, where
		a.	Peak factor for fast-food restaurant is 1.33
		b.	Peak factor for all other food service types is 1.00
	2)	Waste flow rate:
		a.	With dishwasher: 6-gallon flow
		b.	Without dishwasher: 5-gallon flow
		c.	Single-service kitchen: 2-gallon flow
		d.	Food waste disposer: 1-gallon flow
	3)	Retention times:
		a.	Commercial kitchen waste/dishwasher: 2.5 hours
		b.	Single-service kitchen/single serving: 1.5 hours
	4)	Storage factors:
		Fully equipped commercial kitchen:
		a.	8-hour operation = 1
		b.	16-hour operation = 2
		c.	24-hour operation = 3
		Single-service kitchen = 1.5
The Uniform Plumbing Code includes a built-in safety factor that can yield very large grease trap size specifications. At this time, the Borough is not requiring traps larger than 4,000 gallons. However, the minimum size shall be a 1,500-gallon, twin-compartment, reinforced concrete grease trap.

	Method 2 Five-Hour Detention/Peak Flow
	A.	Gallons of water used per hour of operation.
	B.	A x 0.75 = average "gray water" flow per hour.
	C.	B x 1.9 peak flow factor.
	D.	C x 5 hours detention = volume trap.
	Required volume of trap = A x B x C x D

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:

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.

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.

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.

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:

It is the responsibility of the customer (waste generator) to ensure compliance with the Borough of Gibbsboro discharge limitations.

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.

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.

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.

§ 311-29 Grease interceptor construction.

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.

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.

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.

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.

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.

§ 311-30 Service/inspection and monitoring ports.

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.

An inspection port shall be provided for the flow-control device regulating flow into the interceptor.

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.

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.

§ 311-31 Under-the-sink grease interceptors.

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.

General requirements.

The location of such interceptors shall be in as close proximity to the source of wastewater as physically possible.

The lid shall be secured to the body with a single bolt. No wing nuts or screws shall be permitted.

Baffle systems and all other internal pieces shall be removable to facilitate cleaning and replacement, but must be in place at all other times.

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.

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.

Installation requirements.

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.

There shall be sufficient clearance for the removal of the interceptor cover for cleaning.

Unless specifically approved by the Borough Engineer, runs of pipe exceeding 25 feet between fixture and interceptor shall not be permitted.

The interceptor shall not be installed in a waste line from a garbage grinder. Any garbage grinder waste shall bypass the interceptor.

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.

Maintenance requirements.

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.

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.

The grease generator shall maintain adequate documentation that the interceptor is appropriately cleaned and inspected.

§ 311-32 Requirements for interceptor waste generators.

Grease interceptor waste generators shall meet all applicable requirements regarding the accumulation, generation, and disposal of waste in Article II, Connection to System, of this Chapter 311.

§ 311-33 Interceptor maintenance.

Interceptor maintenance service contract.

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.

A contract shall at a minimum:

From the customer:

Contain the customer name, address and telephone number, and the name, address, and telephone number of the facility to be serviced if different.

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.

From the vacuum truck cleaning service:

Contain the vacuum truck company name, address, and telephone number.

Contain the name of a primary and secondary contact person.

[3]

Be signed and dated by an authorized representative indicating acceptance of the terms of the contract.

[4]

The name, address, and telephone number of the disposal site.

[5]

Additionally, the transporter shall provide a:

[a]

Certificate of insurance.

[b]

Certificate of assurance.

[c]

Certificate of indemnification.

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.

Required pumping frequency.

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.

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.

All interceptors shall be maintained by the grease generator at the grease generator's expense.

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.

Interceptor maintenance log.

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.

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.

Cleaning procedures.

The owner or an employee of the facility shall supervise the interceptor cleaning and shall be physically present and observe the entire cleaning operation.

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.

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.

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.

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.

Screening tests for such grease interceptor treatment products shall be designed by the CCMUA.

The results of screening tests shall be subject to technical review by the CCMUA.

Physically removed; or

Have all effluent pumped out, a straight line plumbed from the inlet to the outlet, and the remainder of the tank filled with soil or sand.

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.

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:

Physically removed; or

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

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.

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.
