Prevent FOG From Entering Creeks and Streams Through Storm Drains

BMP Reason Benefits

Do not wash any kitchen equipment or food-bearing items outside.

This discharge will eventually reach the stormwater system and nearby streams.

The discharge of grease and oil to the storm drain system will degrade the water quality of receiving streams by adding biological and chemical oxygen demand to the stream.

Discharge of grease and oil to the storm drain might also result in legal penalties or fines.

Cover outdoor grease and oil storage containers.

Uncovered grease and oil storage containers can collect rainwater. Since grease and oil float, the rainwater can cause an overflow onto the ground. Such an overflow will eventually reach the stormwater system and nearby streams.

The discharge of grease and oil to the storm drain system will degrade the water quality of receiving streams by adding biological and chemical oxygen demand to the stream.

Discharge of grease and oil to the storm drain might also result in legal penalties or fines.

Locate grease dumpsters and storage containers away from storm drain catch basins.

The farther away from the catch basin, the more time someone has to clean up spills or drainage prior to entering the storm drain system.

Be aware of oil and grease dripped on the ground while carrying waste to the dumpster, as well as oil and grease that may ooze from the dumpster.

The discharge of grease and oil to the storm drain system will degrade the water quality of receiving streams by adding biological and chemical oxygen demand to the stream.

Discharge of grease and oil to the storm drain might also result in legal penalties or fines.

Use absorbent pads or other material to clean up spilled material around outdoor equipment, containers or dumpsters.

Do not use free flowing absorbent materials such as "kitty litter" or sawdust that can be discharged to the storm drain system.

Absorbent pads or materials can help clean up grease and oil that is spilled on the ground and prevent it from flowing to the storm drain system.

The discharge of grease and oil to the storm drain system will degrade the water quality of receiving streams by adding biological and chemical oxygen demand to the stream.

Discharge of grease and oil to the storm drain might also result in legal penalties or fines.

Routinely clean kitchen exhaust system filters.

If grease and oil escape through the kitchen exhaust system, it can accumulate on the roof of the establishment and eventually enter the storm drain system when it rains.

The discharge of grease and oil to the storm drain system will degrade the water quality of receiving streams by adding biological and chemical oxygen demand to the stream.

Discharge of grease and oil to the storm drain might also result in legal penalties or fines.
