RE: Plan Check BLD2006845 Old Milltown Remodel at 201 5 Ave South
Dear Mr. Allen,
The following should help clarify grease removal equipment requirements for the Old Milltown
tenant improvement:
For existing facilities: Subject to the
provisions of this subsection, food service facilities operating prior
to February 16, 2004, shall be permitted to install, operate, and
maintain grease traps that are properly sized and installed
according to the City’s guidelines in lieu of grease interceptors.
However, the Director may, in his or her sole discretion, require an
existing facility to install a grease interceptor if the facility meets
one or both of the following conditions: (1) continues to deposit
FOG in the wastewater collection system; or (2) repeatedly
violates BMPs or maintenance standards.
For new facilities: After February
16, 2004, food service facilities which are newly proposed or
constructed, or existing facilities which will be expanded or
renovated to include a food service facility where such facility did
not previously exist, shall be required to install, operate and
maintain a grease interceptor.
The Director may, in his or her sole
discretion, allow new facilities to install a grease trap instead of a
grease interceptor according to the following criteria:
i. A grease trap may be utilized
instead of a grease interceptor if it is demonstrated to the
satisfaction of the Director that the installation of a grease
interceptor is physically impracticable. For purposes of this
determination, “physically impracticable” shall include, but is not
necessarily limited to, the following conditions: (1) the lack of
available space on the premises; (2) unavoidable interference from
underground utilities or structures; and (3) topographical
conditions such as slope that unavoidably prevent installation of a
grease interceptor.
ii. A grease trap may be utilized
instead of a grease interceptor if both of the following conditions
are present: (1) the City’s interceptor sizing formula results in a
required capacity of 500 gallons or less for the facility; and (2) the
facility has a seating capacity of 60 or less; provided, that if either
condition subsequently ceases to exist, the Director may require
said facility to install a grease interceptor.
This means if a food service facility uses Provinces without major modification, it is
grandfathered in and can use a properly sized grease trap. If there is a major modification, such
as the walls being moved or the kitchen being relocated, I would interpret that to be a new
facility and it would not be eligible to be grandfathered.
Please revise plans and resubmit accordingly.
Sincerely;
Jon Lein
