An Ordinance Pertaining to the Installation of Grease Interceptors
And Amending Section 3.10 of the City Code
INTRODUCTION:
Attached is ordinance No. , an ordinance pertaining to the requirement of grease
interceptor installation in establishments that prepare food and amending Section 3.10 of
the City Code.
BACKGROUND:
The City created a sanitary sewer policy in April 200S which established guidelines for
maintenance and inspection of the system, an,emergency response, reductions to
inflow/infiltration, training, work schedules, weather conditions, and documentation. This
was created on the recommendation from the League of MN Cities.
The League is also recommending that cities require grease interceptors for places that
prepare food for the public. These include schools, restaurants, cafes, dining rooms,
hotels, motels, bars, taverns, or related businesses. These entities all produce grease.
Generally this grease is washed down the drain as a liquid when it is hot. After it enters
our sewer system, it cools and hardens which reduces or even blocks sewage flow
resulting in a sewer backup.
Our code currently states that it is unlawful to discharge "water or waste which contains
more than 1 ppm. by weight of fat, oil or grease" (Section 3.10 Subd. S). Requiring
grease interceptors would prevent this illegal grease from entering our system. The
interceptor would be located between the plumbing from dishwashers/sinks and our
system. The interceptor would separate grease/oil from allowable discharge, The grease
is stored in the interceptor until the owner provides regular maintenance and cleaning
where the grease will then be properly disposed.
Attached is a copy of the Loss Control Memo from the League of MN Cities. The main
reason that the League is recommending requiring grease interceptors is to reduce the
city's liability in the event of a sewer backup, According to the memo, cities can be held
liable ifthey do not attempt to mitigate grease problems in the sanitary sewer system.
Many cities have already implemented grease interceptor ordinances including
Bloomington, Mankato, Montrose, Woodbury, and Jordan.
AL TERNA TIVES:
1. Adopt Ordinance No. " an ordinance pertaining to the installation of grease
interceptors and amending Section 3.10 of the City Code.
2. Deny Ordinance No.
3. Table for additional information,
RECOMMENDATION:
Staff recommends alternative No.1, to adopt Ordinance No.
