No person shall discharge, or cause to be discharged, any wastewater
from FSEs directly or indirectly into the public sewer without first
obtaining a FOG WDP pursuant to this chapter.
(Ord. 4683 § 1, 2008)
No FSE shall discharge FOG, or cause FOG to be discharged into the public sewer that causes an SSO, exceeds a concentration level set forth in Section
14.26.140 or that may accumulate and/or cause or contribute to blockages in the public sewer or the public sewer lateral which connects the FSE to the public sewer.
(Ord. 4683 § 1, 2008)
Any FSE determined by the director to have contributed to a
sewer blockage, SSO or any public sewer obstruction resulting from
the discharge of wastewater or waste containing FOG, shall be ordered
to install and maintain a grease interceptor, and may be subject to
a plan to abate the nuisance created by sewer line failures and blockages,
SSOs or any other public sewer obstruction. SSOs may cause threat
and injury to public health, safety, and welfare of life and property
and are hereby declared public nuisances. Furthermore, sewer lateral
failures and SSOs caused by FSEs alone or collectively, are the responsibility
of the private property owner, FSE, and individuals who are responsible
officers or owners of the FSE. If the director determines that the
public health and safety require the city to act immediately to contain
and clean up any SSO caused by blockage of a private or public sewer
lateral or system serving an FSE, or if the city so acts at the request
of the property owner or operator of the FSE, or because of the failure
of the property owner or FSE to abate the condition causing immediate
threat of injury to the health, safety, welfare, or property of the
public, the city's costs for such abatement may be entirely borne
by the property owner or the owner/operator of the FSE, and individuals
who are responsible officers or owners of the FSE and may constitute
a debt to the city, due and payable upon the city's request for reimbursement
of such costs depending upon the director's determination of the cause
of the SSO.
(Ord. 4683 § 1, 2008)
Every FSE shall implement BMPs in its operations, in accordance
with the requirements and guidelines established by the director,
to minimize the discharge of FOG to the grease control device and/or
the public sewer. Detailed requirements for BMPs shall be specified
in the FOG WDP and all FSEs are required, at a minimum, to comply
with the BMPs set forth therein as well as any additional BMPs established
by the director. BMPs may include, but are not limited to, kitchen
practices and employee training procedures that are essential in minimizing
FOG discharge to the public sewer.
(Ord. 4683 § 1, 2008)
FSEs are prohibited from doing any of the following:
A. Installing
food grinders in the plumbing system of new construction. All FSEs
that undergo a change in operations or remodeling shall remove any
existing food grinders concurrent with such change or remodeling,
except as otherwise expressly allowed by the director.
B. Introducing
any additives into an FSE's plumbing system, grease trap and/or grease
interceptor for the purpose of emulsifying FOG, biologically and/or
chemically treating FOG for grease remediation and/or as a supplement
to grease interceptor maintenance, unless a specific written authorization
from the director is first obtained.
C. Disposing
waste cooking oil into the public sewer or storm drain. All waste
cooking oils shall be collected and stored properly in receptacles
such as rendering bins, barrels or drums for recycling or other acceptable
methods of disposal.
D. Discharging
wastewater with temperatures in excess of 140 degrees Fahrenheit into
any grease control device, including grease traps and grease interceptors.
E. Discharging
wastes containing fecal materials from toilets, urinals, washbasins
or other fixtures to waste lines directed to grease interceptors and/or
other grease control devices, or vice versa.
F. Discharging
a FOG and solid materials removed from a grease control device to
the public sewer. Grease removed from grease interceptors shall be
waste hauled to an approved disposal site as part of the operation
and maintenance requirements for grease interceptors.
G. Operating
grease interceptors with FOG and solids accumulation exceeding 25
percent of the design hydraulic depth of the grease interceptor.
H. Discharging FOG and other pollutants above the local discharge limits set forth in Roseville Municipal Code Section
14.26.140.
(Ord. 4683 § 1, 2008)
Every FSE is required at the time of construction, remodel and/or change in operations to install, operate and maintain an approved type and adequately sized grease interceptor necessary to maintain compliance with the objectives of this chapter, subject to the variance and waiver provisions of Section
14.14.130. The grease interceptor shall be adequate to separate and remove FOG contained in wastewater from FSEs prior to discharge to the public sewer as determined by the then current Uniform Plumbing Code (UPC). Fixtures, equipment and drain lines located in the food preparation and clean up areas of any FSEs that are a source of FOG discharges shall be connected to the grease interceptor. Compliance shall be established as follows:
A. New
construction of FSEs. New construction of any FSE shall include complete
installation of an approved type and adequately sized grease interceptor,
with a minimum size of 1,000 gallons, prior to commencing discharges
of wastewater to the public sewer.
B. Existing
FSEs.
1. Any
existing FSE, which, in the director's determination, has caused or
contributed to grease-related blockage in the public sewer, has one
or more sewer laterals connected to hot spots and/or has contributed
significant FOG to the public sewer, shall be deemed to have reasonable
potential to adversely impact the public sewer and shall be required
to install grease interceptors within 180 days upon issuance of written
notification by the director.
2. Any existing FSE or FSE that changes ownership or that undergoes remodeling and/or a change in operations, as defined in this chapter, shall be required to install a grease interceptor or to obtain a variance or waiver in accordance with Section
14.14.130.
(Ord. 4683 § 1, 2008)
Any owner of a commercial property where FSEs are located or
their official designee shall be responsible for the installation
and maintenance of a grease interceptor serving multiple FSEs that
are located on a single parcel.
(Ord. 4683 § 1, 2008)
