Building Permit Department.
2. 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:
a. The facility does not have a grease interceptor or trap;
b. The facility has an undersized, nonrepairable, or defective grease
interceptor or trap;

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.
4. 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:
a. That application be made in writing to the Community Development
Director or designee prior to November 1, 2008 requesting an exemption;
b. That an exemption be granted only for a food service facility that
produces a minimal amount of FOG;
c. 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;
d. That the burden or proof is on the food service facility's owner/operator;
e. 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;
f. 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;
g. That the determination of the Community Development Director or designee
may be appealed by the food service facility owner/operator to the
City Manager within five working days of the date it is mailed; and
h. That the exception may be unilaterally revoked pursuant to any requirement
of the State of Oregon, Clackamas County Service District No. 1, or
the United States whose effect is to require a grease trap or grease
interceptor.
E. Maintenance
of Grease Interceptor/Trap Required
1. 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.
2. 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.
3. 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:
c. Total volume of the interceptor/trap;
d. Total volume of material removed from the interceptor/trap;
e. List of all deficiencies identified from an inspection of the empty
interceptor/trap;
f. Name and address of the grease trap service company;
g. Name and address of final disposal site;
h. Signature of the grease trap service company employee performing
the work, if applicable;
i. Signature of the discharger's employee observing and accepting the
services;
j. Receipt for payment for proper disposal of FOG and solids, if such
services are not provided by a grease trap service company.
4. 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.
F. Disposal
of Wastes From Interceptors and Traps
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.
G. Collection,
Storage, and Disposal of Waste Grease and Solids
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.
H. Clean
up of Spilled Grease and Oil
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. In the event that
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.
I. Use
of Chemicals and Other Additives
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 subsection
K of this section.
J. Right
of Access
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 wastestream, 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.
K. Enforcement
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:
1. 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.
2. 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.
3. 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.
4. Civil
Penalties
A person found to have committed a violation of this title shall
be assessed a penalty of not more that $500 per day per violation,
for violations of this section.
5. 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.
L. Best
Management Practices
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."
(Ord. 1972 § 1, 2007; Ord. 1985 § 2, 2008; Ord. 1990 §§ 1, 2008)
A. Users
of sanitary sewer service shall be charged such fees as are established
by resolution of the City Council.
B. When
a sewer system user has industrial or commercial waste of unusual
strength or character, the City reserves the right to reject the application
for service, to require certain pretreatment of such waste or require
the sewer system user to pay such charges as may be fixed by the City
for such waste disposal.
C.
1. The
City shall prepare and mail billings for sanitary sewer services on
the last business day of each month. Payment is due by the 15th of
the month following the billing date. An account is delinquent if
the City does not receive full payment by 5:00 p.m. on the last business
day of the month immediately following the billing date.
2. A
delinquent fee in an amount established by resolution of the City
Council shall be added to all delinquent accounts.
3. The
City shall charge a fee of 10% per year on all accounts that remain
delinquent for more than three months to cover interest and collection
costs.
4. The
Finance Director (or designee) is authorized to determine what constitutes
a de minimis account balance and to waive the penalties in paragraphs
2 and 3 of this subsection in de minimis or extenuating circumstances.
5. The City may require deposits prior to providing sanitary sewer service or in lieu of a deposit, obtain a signed agreement from the property owner, whether the user of the system or not, that they will be ultimately liable for the user charges and that the City may use a lien as one method to secure payment if the charges are not paid. However, the City may not require a property owner to sign such an agreement. The lien attaches to real property and may be enforced pursuant to Section
13.04.130.
6. In addition to other lawful remedies, the Finance Director may enforce the collection of charges authorized by this chapter by withholding delivery of water to any premises where the sanitary sewer service fees are delinquent or unpaid, following the procedures and standards for shutting off water service for nonpayment of water bills as provided in Chapter
13.04. However, the Finance Director shall not deny or shut off water service to any subsequent tenant based upon an unpaid claim for services furnished to a previous tenant who has vacated the premises.
