OLYMPIA FOG REGULATIONS

For the last several years, the City of Olympia has been working to develop educational efforts to help reduce and eliminate the discharge of fats, oils, and grease (FOG) into local sewer systems. Working in cooperation with LOTT Clean Water Alliance (Lacey, Olympia, Tumwater, and Thurston County), the city has been able to regularly survey its FOG-producing food service establishments (FSEs). By doing so, Olympia has been able to be extremely proactive in providing technical assistance and guidance to help local FSEs reach compliance and wastewater pretreatment standards outlined in OMC 13.20.

FOG Prohibitions and Grease Traps

Similar to other cities in Western Washington, Olympia’s Municipal Code has clear guidelines and regulations regarding Publicly Owned Treatment Works (POTWs) universally adopted by all of Thurston County. This includes prohibitions of waste discharge into POTWs, including but not limited to FOG. Per OMC 13.08.150 and OMC 13.20.050, the discharge of any waste or water containing FOG, regardless of accepted state and federal Maximum Concentration Limit, is prohibited.

Olympia Municipal Code also states that, at the discretion of the Executive Director and City, any waste producing business, have an appropriately sized grease trap installed and regularly serviced. Furthermore, all grease traps must be in compliance with not only City and State rules and regulations, but also those of the Uniform Plumbing Code. Grease Traps are an integral part of any effective water pretreatment plan. Regular service and maintenance of a grease trap will not only keep your business in compliance with Olympia and LOTT, but will also minimize damage, clogs, or blockage of your pipes, keeping your FSE running smoothly.

LOTT Clean Water Alliance Best Management Practices

The City of Olympia and LOTT have created comprehensive best management practices (BMPs) for FSEs and other FOG producing businesses to minimize waste discharge, particularly in regard to grease trap maintenance. If the level of FOG exceeds 25% of the tank capacity, ANY grease trap will become ineffective and waste will start to be discharged. How often you fully service your grease trap, however, can vary depending on the size of your grease trap and the rate at which your business produces waste. For lower volume grease traps, LOTT and the City of Olympia recommend skimming floating grease out of the trap at least once a week and thoroughly cleaning your trap every 1 to 2 months.
