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.

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.
