Ensuring that hazardous materials (HazMat) and solid waste encountered or generated by our transportation projects are handled in a manner that is cost effective, environmentally responsible, and protective of agency cleanup liability is an important aspect of our work. Successful management of HazMat stems from early planning and coordination between Washington State Department of Transportation (WSDOT) staff, contractors and regulators.

Training

We provide online training for WSDOT staff who review Spill Prevention, Control, and Countermeasures Plans. WSDOT staff can access the course through LMS by searching for the course title, “WSDOT ENV: Spill Plan Reviewer Training (OLT).”

When conducting environmental work, the Washington State Department of Transportation (WSDOT) follows all state, federal, and local rules and regulations. The following resources, organized alphabetically, are a few of the most common governing requirements: 

Learn how to determine if your site needs hazardous waste sampling prior to construction, how to request sampling by certified personnel, and how to document hazardous materials considerations for your site.
Find information about Spill Prevention, Control, and Countermeasures Plans (SPCC), which are required for many construction projects, as well as what to do if your project experiences a spill or encounters contamination. This page compiles all the necessary resources for SPCC creation and implementation.
Construction projects handle many different types of hazardous waste through reuse, recycling, and disposal avenues. Find out about options and requirements for handling your project’s waste here.
Underground storage tanks (UST) on project sites may be known prior to construction or encountered during earthwork. Find instructions to ensure all USTs and releases from them are handled properly.
