(a) Purpose. The purpose of this section is to control discharges into the public sewerage collection system and wastewater treatment plant that interfere with the operations of the system, cause blockage and plugging of pipelines, interfere with normal operation of pumps and their controls, and contribute waste of a strength or form that either causes treatment difficulties or is beyond the treatment capability of the wastewater treatment plant.
(b) Definitions.
(1) Grease - Material composed primarily of fats, oil, and grease (FOG) from animal or vegetable sources. The terms fats, oil, and grease shall be deemed as Grease by definition. Grease does not include petroleum based products.
(2) Grease Trap -A device for separating and retaining waterborne greases and grease complexes prior to the wastewater exiting the trap and entering the sanitary sewer collection and treatment system. These devices also serve to collect settable solids, generated by and from food preparation activities, prior to the water exiting the trap and entering the sanitary sewer collection and treatment system.
(3) Food Service Facilities - Those establishments primarily engaged in activities of preparing, serving, or otherwise making available for consumption foodstuffs and that use one of more of the following preparation activities: cooking by frying (all methods), baking (all methods), grilling, sauteing, rotisserie cooking, broiling (all methods), boiling, blanching, roasting, toasting, or poaching. Also included are infrared heating, searing, barbecuing, and any other food preparation activity that produces a hot, non-drinkable food product in or on a receptacle that requires washing, These facilities include restaurants, cafeterias, hotels, motels, hospitals, nursing homes, schools, grocery stores, prisons, jails, churches, camps, caterers, manufacturing plants, or any other sewer users as determined by the Town's Wastewater Collection System Superintendent (WCSS) who discharge applicable waste.
(4) User - Any person or establishment including those located outside the jurisdictional limits of the Town who contributes, causes, or permits the contribution or discharge of wastewater in the Town's wastewater collection or treatment system, including persons who contribute such wastewater from mobile sources, such as those who discharge hauled wastewater.
(5) Oil/Water Separator - An approved, industry standard system that is specifically designed, and manufactured to separate oil from water. The system shall allow the oil to be collected and removed on a regular basis as to prevent it from being discharged into the wastewater collection system. Only oil/water separators manufactured for that specific operation will be approved. Adequate support literature from the manufacturer will be required so as to allow a proper review by the WCSS.
(c) Control Plan for (FOG) and Food Waste.
(1) Any new construction, renovation or expansion of Food Service Facilities shall be required to submit to the Town a FOG and food waste control plan that will effectively control the discharge of undesirable materials into the wastewater collection system.
(2) Any existing Food Service Facilities shall also be required to submit a FOG and food waste control plan that will effectively control the discharge of undesirable materials into the wastewater collection system. Existing facilities shall not be exempt from the requirement of this article. There will be no "Grandfathering".
(d) General Criteria.
(1) Installation Requirements. All existing, proposed, or newly remodeled Food Service Facilities that are tied onto our sanitary sewer lines service area shall be required to install, at the user's expense, an approved, properly operated and maintained grease trap.
(2) Sanitary Sewer Flows. Sanitary sewer flows from toilets, urinals, lavatories, etc. shall not be discharged into the grease trap. These flows shall be conveyed separately to the sanitary sewer service lateral.
(3) Floor Drains. Only floor drains which discharge or have the potential to discharge grease shall be connected to a grease trap.
(4) Garbage Grinders/Disposers. It is recommended that solid food waste products be disposed of through normal solid waste/garbage disposal means. If a grinder/disposal is used it must be connected to the grease trap. The use of grinders is discouraged since it decreases the operational capacity of the grease trap and will require an increase pumping frequency to ensure continuous and effective operation.
(5) Dishwashers. Commercial dishwashers must be connected to the grease trap. Dishwashers discharge soap and hot water which can melt grease and allow it to pass through an undersized grease trap. Traps must be sized accordingly to allow enough detention time to allow water to cool and grease to solidify and float to the top of the trap.
(6) Location. Grease traps shall be installed outside the building upstream from the sanitary sewer service lateral connection. This will allow easy access for inspection, cleaning, and removal of the intercepted grease at any time. A grease trap may not be installed inside any part of a building without written approval by the WCSS.
(7) Pass Through Limits. No user shall allow wastewater discharge concentration from grease trap to exceed 100MgPL (milligrams per liter) as identified by EPA method 413.
(e) Design Criteria.
(1) Construction. Grease traps shall be constructed in accordance with The Town of Eleanor's standards and shall have a minimum of two compartments with fittings designed for grease retention. All grease removal devises or technologies shall be subject to the written approval of the WCSS or Plant Superintendent. Such approval shall be based on demonstrated removal efficiencies of the proposed technology.
(2) Access. Access to grease traps shall be available at all times, to allow for their maintenance and inspection. Access to trap shall be provided by two manholes (one on each compartment) terminating at finished grade with cast iron frame and cover.
(3) Load-Bearing Capacity. In areas where additional weight loads may exist, the grease trap shall be designed to have adequate load-bearing capacity. (Example: vehicular traffic in driving or parking areas).
(4) Inlet and Outlet Piping. Wastewater discharging to a grease trap shall enter only through the inlet pipe of the trap. Each grease trap shall have only one inlet and one outlet pipe.
(5) Grease Trap Sizing. The required size of the grease trap shall be calculated using EPA-2 model. All grease traps shall have a capacity of not less the 500 gal. nor exceed a capacity of 3,000 gal. If the calculated capacity exceeds 3,000 gal., multiple units plumbed in series shall be installed.
(f) Grease Trap Maintenance.
(1) Cleaning/Pumping. The user at the user's expense shall maintain all grease traps to assure proper operation and efficiency and maintain compliance with the Town's Pass Through Limits. Maintenance of grease trap shall include the complete removal of all content, including floating materials, wastewater, and bottom sludge and solids. This work shall be performed by a qualified and licensed hauler. Decanting or discharging of removed waste back into the trap from which it was removed or any other grease trap, for the purpose of reducing the volume to be disposed, is prohibited. This service shall also include a thorough inspection of the trap and its components. Any needed repairs shall be noted. Repairs shall be made at the user's expense.
(2) Cleaning/Pumping Frequency. The grease trap must be pumped out completely a minimum of once every four months, or more frequently, as determined by the WCSS, as needed to prevent carry over of grease into the sanitary sewer system.
(3) Disposal. All waste removed from each grease trap must be disposed of at a facility approved to receive such waste in accordance with the provisions of this program. In no way shall the pumpage be returned to any private or public portion of the Town's sanitary sewer collection system. All pumpage from grease traps must be tracked by a manifest, which confirms pumping, hauling, and disposal of waste. The customer must obtain and retain a copy of the original manifest from the hauler.
(4) Maintenance Log. A grease trap cleaning/maintenance log indicating each pumping for the previous 24 months shall be maintained by each Food Service Facility. This log shall include the date, time, amount pumped, hauler, and disposal site and shall be kept in a conspicuous location of inspection. Said log shall be made available to the WCSS or his representative upon request.
(5) Submittal of Records.
A. Each user shall submit all cleaning and maintenance records to the WCSS. The maintenance records shall include the following information:
1. Facility name, address, contact person, and telephone number.
2. Company name, address, telephone number, and contact name of person responsible for performing the maintenance, cleaning, pumping, or repair of grease trap.
3. Types of maintenance performed.
4. Dates maintenance was performed.
5. Date of next scheduled maintenance.
6. Copes of manifests.
7.
B. The user shall be required to submit maintenance records to the WCSS on a biannual basis (twice per year). Records shall be submitted by March 1st and September 1st of each year. The records shall be submitted to: The Town of Eleanor, Attn: Wastewater Collection System Superintendent, P.O. Box 185, Eleanor, WV 25070
C. The WCSS will perform periodic inspections of these facilities and shall notify the user of any additional required maintenance or repairs. Upon written notification by the WCSS, the user shall be required to perform the maintenance and records of said maintenance within 14 calendar days. Upon inspection by the WCSS, the user may be required to install, at his own expense, additional controls to provide a complete system which prevents discharges of undesirable materials into the wastewater collection system.
(g) Additives. Any biological additive(s) placed into the grease trap or building discharge line including but not limited to, enzymes, commercially available bacteria, or other additives designed to absorb, purge, consume, treat, or otherwise eliminate fats, oils, and grease shall require written approval by the Plant Superintendent, or WCSS prior to use. The use of such additives shall in no way be considered as a substitution to the maintenance procedures required herein.
(h) Chemical Treatment. Chemical treatments such as drain cleaners, acid, or other chemical solvents designed to dissolve or remove grease shall not be allowed to enter the grease trap.
(i) Sand, Soil, and Oil Interceptors. All car washes, truck washes, garages, service stations, car and truck maintenance facilities, fabricators, utility equipment shops, and other facilities (as determined by the WCSS) that have sources of sand, soil, and oil shall install effective sand, soil and oil traps, interceptors, and/or oil/water separators. These systems shall be sized to effectively remove sand, soil, and oil at the expected flow rates. These systems shall be, at the user's expense, cleaned or pumped on a regular basis to prevent impact upon the wastewater collection and treatment systems. Users whose systems are deemed to be ineffective by the WCSS shall be asked to change the cleaning frequency or to increase the size of the system. Owners or operators of washing facilities will be required to prevent the inflow of detergents and rainwater into the wastewater collection system. Oil, water separator installations shall be required at facilities that accumulate petroleum oils and greases and at facilities deemed necessary by the WCSS.
(j) Laundries. Commercial laundries shall be equipped with an interceptor with a wire basket or similar device, removable for cleaning, that prevents passage (into the wastewater collection system) of solids ½ inch or larger in size such as rags, strings, buttons, or other solids detrimental to the system.
(k) Control Equipment. The equipment of facilities installed to control FOG, food waste, sand, soil, oil, and lint must be designed in accordance with the Plumbing Code, the WV Department of Environment and Conservation guidelines, most current engineering standards, or other applicable guidelines approved by the WCSS. Underground equipment shall be tightly sealed to prevent inflow of rainwater and shall be easily accessible to allow regular maintenance and inspection. Control equipment shall be maintained by the owner and/or operator of the facility as to prevent a stoppage of the wastewater collection system, and the accumulation of FOG, food waste, sand, soil, oil and lint in the collection lines, pump stations, and wastewater treatment plant. If the Town of Eleanor is required to clean out the wastewater collection lines, as a result of a stoppage resulting from poorly maintained control equipment (or lack thereof) the owner or operator shall be required to refund the labor, equipment, materials, and any overhead costs to the Town including any fines incurred due to any sanitary sewer overflow due directly to the stoppage. The Town retains the right to inspect and approve any and all installations of control equipment.
(l) Alteration of Control Methods. The Town of Eleanor, through the WCSS, reserves the right to request additional control measures if existing control equipment is shown to be insufficient to protect the wastewater collection system and wastewater treatment plant from interference due to the discharge of FOG sand, soil, lint, or any other undesirable materials.
(m) Enforcement and Penalties. Any person who violates this ordinance, in part or whole, shall be subject to a written warning for the first violation, a $1,000 civil penalty for the second violation, a $1,500 civil penalty for the third violation, and a $2,000 civil penalty for the fourth violation within a two- year period. Consistent violations will result in a $500 increase in civil penalty and may result in termination of service.
