Who do I contact to report a spill?
To Report Illicit Discharges Or Spills: Contact the Public Works Department at 425.486.2768 during business hours (Monday through Friday, 8 a.m. to 5 p.m.) or after hours, call the Police Department non-emergency number at 425.486.1254. 

If the spill is a direct hazard to human or environmental health, dial 911.  Be assured that all calls will remain anonymous and, if requested, you will not be contacted.  Thank you for being a part of our efforts to clean up our ground and surface water.
What do I do with extra paint?
You could donate it to a local school or other nonprofit organizations for projects.  For latex paint, you can add cat litter or sawdust to the container to dry out the remaining material and place it in your garbage for collection. 

To prevent the amount of remaining paint you have after a project you can use the paint calculator tool to calculate the amount of material to purchase.
