Fats, Oils and Grease (FOG)
Most clogged sewer pipes are caused by fats that have solidified.  It is tempting to pour fats and grease down the drain when they are warm and runny however when FOG cool, they congeal and make a thick gooey mass that clogs sink pipes and sewer drains.  All fats -- including butter, chicken fat, beef drippings, cooking grease, salad oil, and lard -- should be disposed of in the garbage can after being collected in a disposable container.  Don’t place more than 1 quart in your trash. 

Of Special Concern
Pouring FOG down your sink drain can cost homeowners money when their pipes have to be snaked out due to a blockage.  For the city, the costs and hazards of these blockages are substantial; FOG collects in sewer pipes and can cause backups and even push raw sewage into the streets and area streams. 

Disposal
Do not put any fats, cooking oil, grease or lard into your sink drain or down the toilet.  All FOG should be collected in a plastic container, frozen juice container, tin can or a thick plastic bag and placed in your garbage can.  Absorb extra grease with a paper towel before washing the pans.  Greases can also be wicked from the surface of liquids using paper towels or soaked up during cooking.  Simply place the COOLED paper towels into your regular garbage collection.  Always be aware that hot grease can cause burns!

Restaurants or backyard deep-fryers can generate substantial amounts of FOG.  Quantities over one quart may be taken to the Western Placer Waste Management Authority’s HHW Facility.
