The sewage flowing into the City’s wastewater treatment plant currently has high levels of fats, oils and grease which is causing problems with treating the wastewater prior to discharge to the Columbia River.
These problems may lead to violations of water quality standards and pollution of the river resulting in closures of local beaches. The City could be fined by the State for violations.
The primary source is largely generated by food service facilities (schools, community meal centers, food carts, markets, restaurants).
However, residential units also contribute to the problem, hence this notification.
Common Sources of Fat, Oils, and Grease (FOG):
- Fried foods
- Baked goods
- Cooked meats
- Butter and other dairy products
- Gravy and sauces
- Mayonnaise and salad dressings
- Food scraps
What is the big deal?
If fats, oils, and grease drain into the sewer system, they can cause treatment failures, slow draining pipes, clogged pipes, and even sewer backups causing costly private property damage.
Failure to maintain a grease interceptor/trap can lead to fines from the city. Save your money and follow some simple practices that can save your home or your business time and money while protecting Mosier’s sewer system.
Food Service Establishment (FSE)
Oregon Plumbing Specialty Code (OPSC) defines an FSE as a facility that engages in activities of preparing or serving food or beverage for consumption either on or off the premises including, but not limited to, restaurants, cafes, food carts, commercial kitchens, caterers, hotels/motels, prisons, correctional facilities, nursing homes, care institutions.
These establishments are responsible for the installation and maintenance of grease interceptors/traps. The city engineer, at his sole discretion, may require any discharger identified by repeated maintenance problems, to provide an appropriate FOG control plan approved and implemented prior to the renewal or issuance of a business license. The City will issue fines to repeat offenders.
Best Management Practices for All Mosier Residents
Best management practices are activities that manage and control the disposal of FOG. There are some simple steps you can take to reduce your addition of FOG to the sewer system.
