2008-09 Stakeholder Workgroup

In 2008, Ecology established an external stakeholder workgroup to facilitate a collaborative effort with the regulated community and environmental interests to develop a more effective industrial stormwater general permit program. The committee addressed a broad range of related issues, including stormwater research and development, education and outreach, compliance inspections and enforcement.

More information on the Stakeholder Workgroup is available on our 2008-09 Stakeholder Workgroup page at
