The ETAP podcast – a technical service program for state departments of transportation provided by the American Association of State Highway and Transportation Officials – explores a wide array of environmental topics that affect transportation and infrastructure programs.

In this episode, Tony Bush (above) – stormwater branch manager for WSDOT – explains how the agency historically managed stormwater runoff from a safety and road preservation perspective and how it then later built in environmental stewardship and regulatory practices to support that stewardship into its processes.

Bush also goes into a current WSDOT research effort regarding the environmental impact of a contaminant called 6PPd-quinone from old vehicle tires and how that contaminant might affect salmon populations. To listen to this episode of the ETAP podcast, click here.
