Cut Through the FOG when planning or building a food service establishment

Grease TrapThe city’s Cut Through the FOG effort requires food service establishments to install grease interceptors in all new construction or renovations, or when there are changes in tenancy or ownership. Under City Code 17.34.050 and Oregon Specialty Plumbing Code, food service establishments are not authorized to discharge fats, oils and grease (FOG). The new rules state that all FOG conveyance lines must be connected to a grease interceptor aiming for zero FOG and food waste discharge to the city’s sanitary sewer system. Grease interceptors must be cleaned and maintained per manufacturer’s specifications and city staff will inspect them regularly to ensure compliance.
