What is a spill?

A spill is an active discharge where there is an imminent threat to human health or the environment. Spills may include such events as paint, oil, pesticide, antifreeze, and sewage spills near a catch basin. 

What if I cause a spill? 

Report it. Mountlake Terrace code requires that as soon as an individual has information of any known or suspected release of materials which are resulting or may result in illegal discharges or pollutant they shall take all necessary steps to ensure discovery, containment, and cleanup. The individuals shall notify the emergency response program no later than the next business day. 

In the State of Washington, there are mandatory reporting requirements for spills. Please visit the Department of Ecology reporting page for more information on mandatory reporting requirements. 

When you contact the Spill Control Hotline have the following information available: 

  • An address or cross streets 
  • The material that has spilled 
  • The estimated volume of material that spilled
  • What time the spill occurred or when you first observed it
  • Contact information (name and phone number)

Have a spill plan in place

If you are a business, chances are you are required by the Mountlake Terrace Code to have a spill plan and a spill kit on hand to deal with the types and volumes of materials you store on site.
