Adopting emission standards for ocean-going vessels at berth.

HB 1689 requires Washington state to adopt California's existing emission standards for ocean-going vessels while docked at ports, directly affecting ports like Tacoma and Seattle and the surrounding communities disproportionately impacted by diesel pollution. The bill mandates the Department of Ecology to implement these standards, which require ships to use shore power instead of idling engines, reducing diesel particulate matter and greenhouse gases. Compliance would begin no earlier than January 1, 2028, with potential extensions of up to three years. This policy change aims to improve air quality in port communities, aligning with federal clean air act options and state funding for shore power infrastructure.
