Reducing environmental impacts associated with the operation of certain ocean-going vessels.

HB 1652 requires ocean-going vessels operating within three nautical miles of Washington's shoreline to use low-sulfur fuel (max 0.1% sulfur) in all engines and auxiliary boilers starting January 1, 2028. It directly affects commercial vessels over 400 feet long, over 10,000 gross tons, or equipped with large marine engines, excluding tugboats and tank vessels meeting specific size criteria. The bill mandates detailed record-keeping of fuel types, sulfur content, and fuel-switching procedures during port visits. These requirements aim to reduce harmful air pollution from vessel emissions near Washington communities and shorelines.
