In order to provide for the public health and welfare, to ensure
the adequate maintenance and operability of the wastewater collection
and treatment infrastructure, and to comply with the laws and regulations
of the State of Oregon, and the United States, it is necessary to
set uniform requirements for all users of the City's sanitary
sewer system to include, but not limited to, the following:
(A)
To establish the appropriate authority for the City to condition
or deny discharges to the City sewer system;
(B)
To prevent the introduction of excessive amounts of grease into
the City sewer system;
(C)
To prevent the clogging or blocking of the City sewer lines
due to grease buildup that cause backup and flooding of streets, residences,
and commercial buildings;
(D)
To implement a set of procedures to recover the costs incurred
when grease blockages require the City to engage in cleaning and maintenance
of sewer lines and the disposal of grease blockages;
(E)
To implement a procedure to recover costs from the parties responsible
for contributing waste products to the City system for the cost of
any liability incurred by the City for damage caused by grease blockages
resulting in the flooding of streets, residences, or commercial buildings;
(F)
To establish enforcement procedures for violations of any part
or requirement of this section; and
(G)
To establish the authority for the City to carry out routine
and nonroutine monitoring (sampling and inspections) of the grease
traps of any food service facility either in the City or outside,
that contributes waste products that enter the City system.

(A)
General Requirements. Except as provided otherwise in this subsection,
grease interceptors and/or traps shall be provided by the food service
facility owner to prevent FOG from entering the sanitary sewer system.
The owner shall provide documentation and/or calculations on all sizing
and model selections to Yamhill County Building Department for approval
prior to installation. The grease interceptor or trap shall be easily

grease interceptor or trap users must provide manufacturer's
capacity data and an estimate of the product rate at the facility
that is within the capacity of the grease interceptor or trap to be
approved by the Yamhill County Building Department.
(B)
Existing Facilities. For the purposes of sizing and installation
of grease interceptors/traps, all food service facilities existing
within the City's sewer system service area, whether within,
or without, the City limits, prior to the effective date of the ordinance
codified in this section shall be allowed to operate and maintain
existing grease interceptors/traps provided their grease interceptors
or grease traps are maintained in efficient operating conditions.
Except as provided otherwise in this subsection, on or after
the effective date of the ordinance codified in this section, the
City shall require an existing food service facility to install, operate,
and maintain a new grease interceptor or trap that complies with the
requirements of this section or to modify, repair, or replace any
noncompliant interceptor or trap within 90 days of written notification
by the City when any one or more of the following conditions exist:
(1)
The facility does not have a grease interceptor or trap;
(2)
The facility has an undersized, nonrepairable, or defective
grease interceptor or trap;
(3)
Remodeling of the food preparation or kitchen waste plumbing
system is performed which requires a building permit to be issued
by the City; or
(4)
The existing facility does not have plumbing connections to
a grease interceptor or trap in compliance with the requirements of
this section, or current building codes.

sewer line between all fixtures which may introduce grease into the
sewer system and the connection to the City's wastewater collections
system. Garbage disposals, dishwashers, and restrooms shall not be
plumbed to the grease interceptor. Automatic hood washers, floor drains
in food preparation and storage areas shall be plumbed to the grease
interceptor. Sanitary facilities (restrooms) shall not be plumbed
to the grease interceptor under any circumstance.
(D)
Pre-existing Operations. A food service facility operating prior
to the effective date of the ordinance codified in this section may
apply for an exception to the requirement that it install a grease
interceptor or grease trap under the following conditions:
(1)
That application be made in writing to the City requesting an
exemption;
(2)
That an exemption be granted only for a food service facility
that produces a minimal amount of FOG;
(3)
That the determination that a minimal amount of FOG is being
produced shall be based on a comparison of the food service facility's
production of FOG as compared to all food service facilities subject
to the provision of this section. In determining the production of
FOG relative to other food service providers, inferences may be drawn
from a comparison of the total amount of discharge to the wastewater
system, the volume of products likely to produce a heavier concentration
of FOG, and the active employment of practices that remove FOG prior
to its discharge to a grease trap or grease interceptor;
(4)
That the burden or proof is on the food service facility's
owner/operator;
(5)
That the intention of this exception is to provide relief only
to those whose production and discharge of FOG would not constitute
more than a minor contribution to the system;
(6)
That the food service facility's owner/operator consents
to an annual review and inspection at which it shall be determined
whether the food service facility has implemented changes that increase
its production of FOG; and
(7)
That the exception may be unilaterally revoked pursuant to any
requirement of the State of Oregon, or the United States whose effect
is to require a grease trap or grease interceptor.
(Ord. 541, 1/10/2024)
(A)
Maintenance. All grease interceptors and grease traps shall
be continuously maintained in satisfactory and effective operational
condition by the discharger at the discharger's expense. Typically
maintenance consists of the removal of floatable solids and settleable
solids collected in the grease interceptor/trap; and the cleaning
of the walls and piping.
(B)
Routine Maintenance Schedules. The discharger is responsible
for establishing a routine maintenance schedule that includes the
routine removal of floatable and settleable solids and cleaning of
the interceptors/traps. The maintenance frequency should be such that
the interceptor/trap does not allow fats, oils, grease, and food solids
to leave the interceptor and enter the City sewer collection system.
The amount of time between pumping and cleaning services is dependent
on the volume of wastes discharged, the volume of the interceptor/trap,
and the physical integrity of the interceptor/trap structures and
piping. It is the discharger's responsibility that the interceptors/traps
are routinely inspected and repaired as needed.
(C)
Record Keeping Requirements. The discharger is responsible for
maintaining appropriate maintenance records that document the routine
pumping, cleaning, and repairs made to interceptors and traps. Where
the discharger hires a grease trap service company to clean the interceptor/trap
and remove and dispose of the accumulated grease and solids, a copy
of the pumping manifest or billing must be retained with the maintenance
records. Where the discharger does not hire a grease trap service
company the discharger shall maintain a receipt for proper disposal
of the accumulated FOG and solids. All maintenance records should
include at a minimum the following information:
(1)
Name of facility;
(2)
Date service performed;
(3)
Total volume of the interceptor/trap;
(4)
Total volume of material removed from the interceptor/trap;
(5)
List of all deficiencies identified from an inspection of the
empty interceptor/trap;
(6)
Name and address of the grease trap service company;
(7)
Name and address of final disposal site;
(8)
Signature of the grease trap service company employee performing
the work, if applicable;
(9)
Signature of the discharger's employee observing and accepting
the services;
(10)
Receipt for payment for proper disposal of FOG and solids, if
such services are not provided by a grease trap service company.
(D)
Record Retention. All grease interceptor/trap maintenance records
shall be retained for a period of no less than three years. These
records shall be retained at the food service facility and shall be
made available for inspection by the City.
(Ord. 541, 1/10/2024)
Storage, handling, transportation, and disposal of all wastes
from interceptors/traps shall be performed in accordance with applicable
Federal, State, and local regulations that pertain to the type and/or
class of waste. Materials removed from waste interceptors/traps must
be disposed of at State of Oregon Department of Environmental Quality
(DEQ) designated locations for those specific type wastes. Materials
removed from waste interceptors/traps shall not be discharged to the
City sanitary sewers or storm drains.
(Ord. 541, 1/10/2024)
Dischargers are encouraged to collect excess oil and grease
from deep fat fryers, pots, and pans prior to washing. This waste
grease and oil should be collected and stored in appropriate containers
that are appropriately labeled. The collected waste grease and oil
should be collected by a waste grease service company for disposal.
In no case shall the discharger dispose of deep fat fryer oils and
other collected waste greases and oils by discharge to the grease
interceptor/trap or to the City sewer system.
(Ord. 541, 1/10/2024)
The discharger shall clean up all spilled grease and oil using
appropriate tools including a mop and bucket. Bucket contents may
be discharged to the grease interceptor/trap, and solid greases and
oils that can be manually picked up should be held in the waste grease
collection containers for final disposal. In no instance shall spilled
grease and oils be washed to the stormwater drains. If the City is
required to clean up a grease and oil spill generated by a discharger,
the City is authorized to assess cost recovery fees to the discharger
for all reasonable documented costs associated with the clean-up.
(Ord. 541, 1/10/2024)
The use of chemicals, emulsifying agents, enzymes, microorganisms, and/or other additives that are added to the grease interceptors/traps to reduce or eliminate the pumping and cleaning of the interceptor/trap is prohibited. Dischargers currently using a chemical or other additive must halt such use immediately on the effective date of the ordinance codified in this section or be subject to citation and fine under Section 3.66.110 of this Chapter.
(Ord. 541, 1/10/2024)
The City, employees of the City, or authorized agents of the
City, have the authority to enter the property of the discharger to
conduct inspections of the entire facility, including the interceptors,
traps, cooking and storage areas, restrooms, offices, service areas,
and other areas of the facility. The City is also authorized to collect
samples of any waste stream, including the discharge from the facility
and the interceptors and traps. The City may obtain search warrants
for inspection and sampling purposes. Failure to grant access may
result in the suspension of sewer and water services provided by the
City.
(Ord. 541, 1/10/2024)
A person failing to comply with the provisions of this section is subject to the short form uniform citation and complaint method and enforcement procedures within Chapter 1.08 of this code. In addition to these enforcement actions the City is authorized to take the following actions to achieve compliance to this section:
(A)
Mandatory Interceptor/Trap Service. The City may issue an order
requiring the discharger to conduct interceptor/trap maintenance services
within a mandatory time period. The cost of the services shall be
the direct responsibility of the discharger.
(B)
Mandatory Interceptor/Trap Service Schedule. The City may impose
a mandatory pumping and cleaning schedule to assure the proper maintenance
of an interceptor not properly maintained by the discharger. The cost
of the services shall be the direct responsibility of the discharger.
Mandatory service schedules may cover a time period of up to three
years.
(C)
Cost Recovery. The City may assess the discharger the amount
of those expenditures made by the City to clean up or prevent sewer
blockages and overflows caused by the discharge from that discharger.
The City may also recover costs associated with any testing performed
for reasons associated with violations or repeat offenders.
(D)
Civil Penalties. A person found to have committed a violation
of this title shall be assessed a penalty of not more than $500.00
per day per violation, for violations of this section.
(E)
Emergency Suspensions. The City may immediately suspend a discharge
and/or water services, after informal notice to the discharger, whenever
such suspension is necessary to stop an actual or threatened discharge
which reasonably appears to present or cause an imminent or substantial
endangerment to the health or welfare of persons.
(Ord. 541, 1/10/2024)
The application of best management practices that have been
developed to minimize the adverse impacts of fats, oil, and grease
discharge is encouraged for all food service facilities and businesses
in the City. The City suggests that food service facilities become
familiar with and implement those practices published in Chapter 3
of the Oregon Association of Clean Water Agencies publication, "Fats,
Oil and Grease Best Management Practices Manual."
