DISCHARGE OF FATS, OILS AND GREASE (FOG) INTO THE WASTEWATER
COLLECTION AM) TREATMENT SYSTEM OF THE CITY OF WEST MEMPHIS;
AND FOR OTHER PURPOSES.
Section 1. Scope and Purpose.
The objective of this ordinance is to aid in preventing the introduction and accumulation of fats,
oils and greases into the City of West Memphis wastewater system which will or tend to cause or
contribute to the sanitary sewer blockages and obstructions. Food Service Establishments and
other industrial and commercial Establishments generating wastewater containing fats, oils and
greases are subject to this ordinance. This ordinance regulates such users by requiring that grease
interceptors/traps and other approved strategies be installed, implemented and maintained in
accordance with the provisions hereof. All interceptors/traps shall be of a type and capacity
approved by the Governing Board. Where a grease interceptor/trap currently exists or is required
by the Governing Board, the owner, leaseholder or operator at his expense shall maintain it for
continuous, satisfactory and effective operation.
The intent of this ordinance is to ensure compliance with the City of West Memphis NPDES Permit
which is required by the Arkansas Department of Environmental Quality (ADEQ)and the United
States Environmental Protection Agency (EPA). This ordinance is in no way intended to discourage
development, but rather to protect the facilities and the City's infrastructure as it relates to the
City's wastewater collection and treatment system.

cause interference or pass through.
Fats, oils, or greases of animal or vegetable origin in concentrations greater than 100 mg/L as
identified by Environmental Protection Agency (EPA)approved methods.
Section 4. Grease Interceptor/Trap Installation, Sizing.
Grease interceptors/traps shall be installed and maintained at the user's expense, when a user
operates a Food Service Establishments (FSE). Grease interceptors/traps may be required in non-
cooking or cold dairy and frozen foodstuffs establishments and other industrial or commercial
establishments when the establishment generates wastewater containing fat or grease and the
Director of Environmental Quality determines an interceptor/trap is necessary to prevent
contribution or accumulation of grease to the collection and treatment system.
When a grease interceptor/trap is required,a detailed plumbing fixture plan must be submitted.
All grease interceptors/traps shall be designed according to minimum standards of the Arkansas
Plumbing Code, Chapter (Traps, Interceptors and Separators), and be of a type, capacity,and
location approved by the Director of Environmental Quality

at their expense. All grease interceptors/traps shall be routinely maintained to prevent the
discharge of any water or waste containing fats, oils, and grease whether emulsified or not, in
excess of 100 mg/L or containing substances which may solidify or become viscous at temperatures
between thirty-two (32) degrees and one hundred fifty (150) degrees Fahrenheit and (0 degrees-
65 degrees Celsius) to the City's collection system.
Any Food Service Establishment whose effluent discharge to the wastewater collection system is
determined by the Director of Environmental Quality to cause interference in the conveyance or
operation of the collection system may be required to sample its grease interceptor/trap discharge
and have it analyzed for oil and grease at the expense of the owner, lease-holder or operator.
Results of such analyses shall be reported to the Director of Environmental Quality.
All grease interceptors/traps shall be serviced and emptied of accumulated waste content as
required in order to maintain minimum design capability or effective volume on the
interceptor/trap, but not less often than every ninety (90) days. This must be done by a licensed
hauler. The required maintenance frequency can be changed by the Director of Environmental
Quality upon written notification from the property owner or food service establishment.
The property owner and/or Food Service Establishments owner/operator shall be responsible for
ensuring that no waste or wastewater pumped from the grease interceptor/trap is reintroduced

considered acceptable interceptor/trap maintenance practices and shall not be used as an
alternative to the pumping of said interceptor/trap.
All grease interceptors/traps shall be maintained in efficient operation at all times by the property
owner and/or Food Service Establishment at the property owner and/or Food Service
Establishment's expense.
If an obstruction of the City's sewer main occurs that causes a sewer overflow to the extent that
an impact on the environment is realized and that said overflows or failure of the collection system
to convey sewage can be attributed in part or in whole to an accumulation of grease in the City's
sewer mains, the Director of Environmnetal Quality will take appropriate enforcement action, as
stipulated in the City's Sewer Use ordinance,against the generator or contributor of such action.
Food Service Establishments whose operations cause or allow excessive fats, oils and grease to
discharge or accumulate in the City's wastewater collection system shall be liable to West Memphis
Utility for costs related to service calls for line blockages, line cleaning, line and pump repairs, etc.

shall be a violation of this ordinance and the City of West Memphis Sewer Use ordinance.
All grease interceptors/traps shall be subject to review, evaluation and inspection by Utility
personnel during normal working hours. Inspections will determine proper maintenance, change in
operation, proper records and files, ability of interceptor/trap to prevent grease from entering the
system and any other factors pertaining to grease management. The Director of Environmental
Quality reserves the right to make determinations of interceptor/trap condition and adequacy
based on review of all information regarding the interceptor/trap performance and required
cleaning, maintenance, modification or replacement. The City may require that the Food Service
