Have a leaky vehicle? Even a single drop on your driveway can mean a shorter lifespan for your car. Leaks are the largest polluters of Puget Sound, so letting your vehicle leak has a major impact on the health of our local waters. Whether you're driving in a leaky vehicle or doing any maintenance in your driveway or street, you should understand what's legal and what's not.
"It shall be prohibited and in violation of this chapter for any person or entity to:
A. Throw, drain, or otherwise discharge, cause or allow others under its control to throw, drain or otherwise discharge into the municipal storm drain system and/or surface and ground waters any materials other than storm water. Examples of prohibited contaminants include but are not limited to the following:
...3. Petroleum products including but not limited to oil, gasoline, grease, fuel oil and heating oil.
4. Antifreeze and other automotive products.
5. Metals in either particulate or dissolved form."
So what does that mean?
It means you can't knowingly let auto fluids leak from your vehicle onto the street. If you know you have a leaky vehicle or are doing maintenance, always use or drop cloth or appropriate container under your vehicle when it's parked to ensure any dripping fluids are contained.
