SUBJECT: Amend TMC Chapter 14 Sewer Discharge to Address Fats, Oils and Greases
ISSUE
Amend and update Chapter 14 of the TMC for unlawful discharge of fats, oils, and greases into
the City's sanitary sewer system.
BACKGROUND
The Federal Clean Water Act prohibits the discharge of fats, oils, and greases (FOG) and King
County Metro does not allow these illicit discharges into the sewer treatment plant. The
discharge of FOG from animal or vegetable origin can block sewer lines. As grease cools, it
adheres to the walls of pipes and eventually obstructs the flow. Food service establishments like
restaurants, cafeterias, and commercial kitchens contribute grease to the sewer system as well
as multi family residential areas. Consequently, additional maintenance is needed to keep
sewer pipes clear.
The highest area of grease is in the Central Business District and is concentrated around the
largest number of restaurants on Southcenter Parkway. Accumulations of FOG are not only
troublesome for pipes but affects sewer lift stations. The grease floats to the surface and has a
tendency to build up in the wet well. A grease `cake' forms and continues to accumulate and it
interferes with the depth gauge readings of the level transducer. The sewer crew will remove
grease twice a month or more as needed.
Restaurants and food preparation establishments are currently required to have grease
interceptors on their kitchen waste lines. Older businesses have been required to retrofit an
interceptor when they apply for a tenant improvement permit. Maintenance and pumping of the
interceptor should be every 1 to 3 months. The City does not have the resources to inspect
private interceptors but can request a schedule of grease interceptor maintenance from the
business. Procedures are needed so that new managers become aware of the requirements.
The Council is being asked to approve this ordinance amending Chapter 14 and consider this
item at the July 13, 2009 Committee of the Whole meeting and the subsequent July 20, 2009
Regular Meeting.

C. NPDES Program Consultant Selection and Agreement
Staff is seeking full Council approval of a consultant agreement with R.W. Beck in the amount of
$24,502 for assistance in adopting a new surface water storm design manual and supporting
documents in order to be in compliance with National Pollutant Discharge Elimination System
(NPDES) Phase II Stormwater requirements.
Per NPDES requirements, the City must adopt a stormwater manual which is equivalent to the 2005
Department of Ecology's Surface Water Design Manual by February 15, 2010. A six -month
extension was granted to all cities from the original due date of August 15, 2009.
R.W. Beck, chosen from the City's current Consultant Roster, will perform professional services to
assist the City in updating relative ordinances, development guidelines, and design and construction
standards to adopt the 2009 King County Surface Water Design Manual with modifications as the
City's own manual. This is anticipated to be a lengthy and detailed process.
Although this item is slightly under the Council approval threshold of $25,000, staff opted to bring
the item forward for approval since any contract changes or supplemental agreements could push the
contract over the approval threshold.
Committee members noted that this requirement is an unfunded mandate. UNANIMOUS
APPROVAL. FORWARD TO JULY 13 COW FOR DISCUSSION.
D. Ordinance Amending TMC Chanter 14 Sewer Discharge of Fats. Oils and Greases
Staff is seeking full Council approval to amend and update the Tukwila Municipal Code (Chapter 14)
relative to the unlawful discharge of fats, oils and greases into the City's sanitary sewer system.
Major changes outlined in the draft ordinance include: an increased emphasis on grease, addition of
an enforcement section and interceptors, and definitions of fats, oils and greases. It is anticipated that
these changes will decrease the maintenance needed to keep City sewer pipelines clear as well as
reduce grease levels in the Central Business District.
Staff noted that an updated copy of draft ordinance reflecting all changes, via strikeout and
underlining, will be included in the July 13 COW agenda packet. UNANIMOUS APPROVAL.
FORWARD TO JULY 13 COW FOR DISCUSSION.
