A. Fats, Oils, Grease, and Sand Interceptors are necessary and shall be
installed, maintained, and used by every Commercial and Industrial property owner and
possessor, and each POTW user in the City, unless specifically exempt by the control
authority, for the proper handling of wastewater containing excessive amount(s) of FOG
or sand; except that such interceptors shall not be required for residential users. All
interceptor units shall be of a type and capacity approved by the POTW control authority
City plumbing inspector or the State of Wisconsin, and shall be so located to be easily
accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned,
and repaired by the user at their expense.
B. All Commercial and Industrial properties, POTW users, and plumbing
installations, other than residential dwelling units, where FOG or similar waste products
of cooking or food are introduced into the POTW shall provide interceptors in
accordance with this Chapter and other applicable laws and regulations. All drains and
drain piping carrying FOG shall be directed through one or more interceptors in
accordance with the State and City plumbing code.
C. New plumbing systems. Notwithstanding the State and City plumbing
codes, every new Commercial and Industrial property and POTW user plumbing system
which discharges to the POTW shall be provided with one or more grease and/or sand
interceptors.
2
1 . Altered or remodeled plumbing systems. Notwithstanding the State
and City plumbing codes, every existing Commercial and Industrial
property and POTW user plumbing system that discharges to the
POTW which is altered or remodeled as to that part of the plumbing
system which discharges from kitchens or food processing area shall
be provided with one or more approved interceptors.
2. Existing Installations. The POTW control authority or City plumbing
inspector may require the installation of an exterior or interior grease or
sand interceptor for existing plumbing installations where the waterway
of a drain system or sewer system is reduced or filled due to sand or
congealed grease, or where sand or congealed grease impairs the
proper functioning or the sewer system.
3. Exterior grease interceptors shall receive the entire waste discharge
from kitchens or food processing areas. Every exterior interceptor shall
be designed, constructed, and installed in accordance with the
standards contained in the State and City plumbing codes, as from
time to time amended or renumbered.
4. No POTW user may intentionally or unintentionally allow the direct or
indirect discharge of any FOG of animal or vegetable origin into the
POTW system in such amount(s) as to cause interference and/or harm
of any kind with or to the City wastewater collection or treatment
system, or as to cause one or more pollutants to pass through the
treatment works into the environment.
5. All users with a grease and/or sand interceptor must adhere to all the
requirements, procedures, and detailed record keeping to ensure
compliance with the requirements of this Chapter. All users shall
maintain such records for not less than seven (7) years and every user
shall render the records available for inspection by a representative of
the POTW during normal business hours. An accurate, complete, and
daily updated maintenance log shall be kept by every user that
indicates, at a minimum:
(a) Date the interceptor was serviced.
(b) Name of person or company servicing the interceptor.
(c) Method of cleaning.
(d) Disposal method of FOG or sand.

6. Cleaning Schedules:
(a) Grease and Sand interceptors shall be cleaned as often as
necessary to ensure that sediment and floating materials do
not accumulate to impair the efficiency of the interceptor; to
ensure the discharge is in compliance with local discharge
limits as identified in COJ ordinance 13.16.100(3); and so
that no visible grease is observed in the discharge.
(b) Grease interceptors shall be completely evacuated not less
than every thirty(30) days, or more frequently when:
(i) Twenty-five percent (25%) or more of wetted height of
the grease interceptor, as measured from the bottom of
the device to the invert of the outlet pipe, contains
floating materials, sediment, fats, oils, or greases; or
(ii) The discharge exceeds BOD, TSS, FOG, PH, or other
pollutant levels established by the POTW; or if there is a
history of non-compliance.
7. Any Person who owns or operates a grease interceptor may submit to
the POTW a request in writing for an exception to the thirty (30) day
cleaning frequency of their grease interceptor. The POTW may grant
an extension for required cleaning frequency on a case-by-case basis
when:
(a) The grease interceptor owner/operator has demonstrated
that the specific interceptor shall produce an effluent,
based on defensible analytical results, in consistent
compliance with established local discharge limits such
as BOD, TSS, FOG, and other parameters as determined
by the POTW, or
(b) Less than twenty-five percent (25%) of the wetted height
of the grease interceptor, as measured from the bottom
of the device to the invert of the outlet pipe, contains
floating materials, sediment, fats, oils, or greases.
8. Prohibited Practices:
4
No Person shall introduce, permit, or cause the introduction of any
surfactant, solvent, or emulsifier into a grease interceptor. Surfactants,
solvents, and emulsifiers are materials which allow the grease to pass
from the grease interceptor into the collection system and include, but
are not limited to, enzymes, soap, diesel, kerosene terrene, and other
solvents.
13.17.040 Compliance Monitoring.
A. Right of Entry:
1 . A representative of the POTW shall have the right to enter the premises of
any user or potential user during normal business hours (7:00 o'clock a.m.
to 3:00 o'clock p.m. Monday — Friday) to determine whether the user is
complying with all requirements of this Chapter and any wastewater
discharge permit or order issued hereunder. Every user shall allow
representatives of the POTW ready access to all parts of the premises at
all times for the purposes of inspection, sampling, records, examination,
coping, remediation, and the performance of any additional duties. Every
user shall have the appropriate tools and staff available to open an interior
grease trap for inspection at all times.
2. Where a user has security measures in force which require proper
identification and clearance before entry is allowed into its premises, the
user shall make necessary arrangements with its security guards so that,
upon presentation of suitable identification, the representative(s) of the
POTW shall be permitted to enter without delay for the purposes of
performing specific responsibilities under this Chapter and otherwise.
3. The POTW shall have the right to set up on the user's property, or require
installation of, such device(s) as are necessary or desirable to conduct
sampling and/or metering of the user's operations under this Chapter. The
costs hereunder shall be at the user's expense.
4. The POTW may require the user to install monitoring equipment as
necessary or desirable to the POTW. The user facility's sampling and
monitoring equipment shall be maintained at all times in a safe and proper
operating condition by the user at its own expense.
5. Any temporary or permanent obstruction to safe and easy access to the
user's facility to be inspected and/or sampled shall be promptly removed
5
•
by the user at the written or oral request of a representative of the POTW
and shall not be replaced. The costs of clearing such access shall be
borne by the user.
6. Unreasonable delay, any obstruction, any hindrance, and any denial in
allowing the POTW access to the user's premises shall be a violation of
this Chapter.
13.17.050 Violations and Enforcement Action.
A. Violation of any and all provisions of this Chapter include, but are not
limited to, failure to clean or pump grease control equipment, failure to maintain grease
control equipment including installation of properly functioning effluent-T and baffles,
failure to install grease control equipment, failure to control FOG discharge, failure to
certify the grease interceptor, being responsible for a sewer line obstruction, being
responsible for a sanitary sewer overflow and using additives so that FOG is diluted or
pushed downstream from connection, and each and every breach of any other provision
set forth in this Chapter.
B. Whenever the City determines that a grease interceptor is in need of
installation, pumping, repairs, maintenance, or replacement, a noncompliance
notification or notice of violation (NOV) shall be issued stating the nature of the
violation(s) and timeframe for corrective measures.
C. If the user fails to initiate action or fully comply with a requirement or
notice, a second notice shall be issued and additional fees assessed. Fees may include
costs associated with service calls for sewer line blockages, line cleaning, camera
trucks, line and pump repairs, including all labor, material, and equipment. Further
noncompliance may result in the discontinuance of the user's facility water service
and/or wastewater service.
D. Immediate discontinuance of water service and/or wastewater service may
be implemented by the City if the user or facility, in the sole determination of a
representative of the POTW and/or City plumbing inspector, present(s) an imminent
endangerment to the health or welfare of persons, the public, or to the environment; or
causes or potentially causes: a stoppage or excessive maintenance to the sanitary
sewer system, significant interference with the Wastewater Treatment Plant, or an
actual or potential violation of any City condition of its permit. Service shall be
reinstated when such conditions have been eliminated as determined by the City.
E. If an inspection or field investigation determines that any fats, oils, and
grease interference or blockage in the sewer system, a sewage pumping station, or the
Wastewater Treatment Plant is caused by a particular user, then that user shall
6
reimburse the City the costs, fees, and expenses of all labor, equipment, supplies, and
disposal incurred by the City to clean the interference or blockage. Failure to reimburse
the City for all such costs, fees, and expenses may result in the termination of water
service and/or wastewater service to that user."
