No food service establishment (FSE) shall discharge or cause
to be discharged into the sewer system polar or nonpolar FOG that
exceeds a concentration specified in Sec. 70-86 or a lower concentration
that accumulates and/or causes or contributes to blockages in the
sewer system or at the sewer system lateral which connects the food
service establishment to the sewer system.
In additions to the prohibitions found in Sec. 70-86, the following
prohibitions shall apply to all food service establishments:
(1)
Discharge of wastes through food grinders and/or garbage-disposal-type
devices to sewer lines intended for grease control device service
is prohibited unless an appropriately sized solids trap is installed
immediately after such grinder or device.
(2)
Discharge of food waste, including food grinder waste that cannot
pass through a one-quarter-inch sieve, is prohibited.
(3)
Discharge of wastes that do not require separation (e.g., urinals,
toilets, wash basins, etc.) to sewer lines intended for grease control
device service is prohibited.
(4)
Introduction of any additives into a food service establishment's
wastewater system for the purpose of emulsifying FOG or biologically/chemically
treating FOG for grease remediation or as a supplement to interceptor
maintenance is prohibited, unless a specific written authorization
from the Director is obtained prior to use.
(5)
Disposal of bulk waste cooking oil into drainage pipes connected
to the POTW, with or without a grease interceptor, is prohibited.
To the extent practical, all waste cooking oils shall be collected
and stored properly in receptacles such as barrels or drums for recycling
or other acceptable methods of disposal.
(6)
Discharge to the POTW of any waste and solid materials removed from
a solids interceptor is prohibited. Solids removed from solids interceptors
shall be disposed of according to applicable regulations.
(a)
All food service establishments, including L-FSEs, shall comply with
applicable provisions specified in Division 4 of this article. A limited
food service establishment, as defined in this article, may or may
not be required to install a grease control device. The Director will
make such determinations on a case-by-case basis.
(b)
General compliance shall be established as follows:
(1)
New construction/tenant finish food service establishments.
New construction FSEs shall include and install one or more grease
control devices as approved by the Director or his/her designee prior
to commencing discharges of wastewater to the POTW, unless otherwise
specified. Potential FSE spaces and tenant finish FSE spaces shall
provide space and plumbing segregation for the future installation
of one or more grease control devices for each tenant space prior
to commencing discharges to the sewer system as determined by the
Director.
(2)
Existing food service establishments.
a.
For existing food service establishments with existing grease
control devices, the grease control device shall be properly operated
and maintained in accordance with manufacturers' instructions and
established BMPs.
b.
Existing food service establishments with grease control devices
which have caused or contributed to grease-related blockage(s) in
the sewer system, or which have sewer laterals connected to "hot spots,"
or which contribute significant FOG to the POTW based on inspection
or sampling may be required to service and clean their grease control
devices on a modified, more frequent schedule as determined by the
Director.
c.
Existing food service establishments without grease control
devices which have caused or contributed to grease-related blockage(s)
in the sewer system, or which have sewer laterals connected to "hot
spots," which contribute significant FOG to the POTW based on inspection
or sampling as per Sec. 70-242, may be required to install an appropriately
sized grease control device.
d.
Food service establishments that undergo remodeling or a change
in operations, as defined in this article, may be required to install
an appropriately sized grease control device.
(3)
Except for specifically identified L-FSEs, all FSEs shall have
a FOG control plan.
(4)
A FOG control plan shall be a written plan that includes the
four minimum elements. In all cases, a copy of published documents,
including manufacturers' publications, may be used to satisfy the
requirements of a FOG control plan. The four minimum elements of a
FOG control plan are as follows:
a.
Written best management practices (BMPs) as identified in Sec.
70 Sec. 70-255(1)b through e.
b.
Written maintenance and operating procedures for each grease
control device, including the maintenance and cleaning schedule.
c.
Written disposal practices for recovered liquid and solid FOG.
d.
Written training program, training schedule, and topics to be
covered during training.
Separate grease control devices shall be installed at food service
establishment located on a single real property parcel unless otherwise
approved by the Director. Maintenance of grease control devices shall
be the responsibility of the FSE operator unless a lease or other
contractual document specifies otherwise.
(a)
Food service establishments found to have contributed to increased
sewer maintenance due to FOG discharges, a sewer blockage, SSO or
any POTW interferences resulting from the discharge of wastewater
or waste containing FOG may be ordered to take steps deemed necessary
by the Director to prevent future problems, including, but not limited
to, the installation and maintenance of a grease control device, and
may be subject to a more restrictive operation and maintenance plan
to abate the nuisance and future problems. Furthermore, sewer lateral
failures and SSOs occurring within the limits of private property
caused by food service establishments, alone or collectively, are
the responsibility of the private property owner or FSE(s).
(b)
If the City must act immediately to clear a sewer blockage or contain
and clean up an SSO caused by blockage of a private or public sewer
lateral or system serving a FSE, or acts at the request of the property
owner or operator, the City's costs for such abatement shall be entirely
borne by the property owner or operator, and shall constitute a debt
to the City.
