A. Businesses such as restaurants, cafes, lunch counters,
cafeterias, bars, clubs, hotels, hospitals, factories, school kitchens,
or other establishments that serve or prepare food where FOG may
be part of the waste stream shall have Grease Traps, Grease
Interceptors, or other approved pretreatment facilities in place to
prevent the discharge of FOG to the sewer system.
B. Such businesses shall have an approved and implemented FOG
Control Plan, and a business license for the business shall not be
renewed or issued without an approved plan being on file with the
city.
13.22.030 FOG Plan Requirements.

C. Increased volume of discharge (increased business) can
become a factor, regarding the efficiency of the grease trap(s). As
discharge volumes increase, the need for a larger grease trap(s) or

waste stream discharge is not maintained within City standards, a
pretreatment system upgrade will be required at the discharger's
expense.

frequency, by demonstrating that all solids and grease layers
reported over the previous twelve (12) months were less
than fifteen (15) percent of the interceptor's capacity. The

Plan to self-clear its grease trap(s) located inside a building
provided:

Businesses that operate automobile and truck repair facilities,
steam cleaning facilities for motorized equipment, car sales lots,
filling stations or any other establishment where petroleum-based
grease and oil may be introduced to the sewer system shall have
pretreatment facilities to prevent the discharge of oil and grease.
These pretreatment facilities must be oil/water separators or
