Paying for response activities for the December 2025 significant atmospheric river and winter event.

HB 2181 allocates $690 million in excess climate commitment auction revenue to repair transportation infrastructure damaged by the December 2025 atmospheric river and winter storm event. It specifically funds cleanup, repairs, and restoration of Interstate 90, State Routes 2, 167, and 410, and other critical transportation systems affected by the emergency. The funding comes directly from the Climate Investment Account, as authorized by the Climate Commitment Act, and is tied to emergency proclamation 25-07. This bill uses existing climate revenue for immediate infrastructure recovery, without creating new taxes or altering broader climate program requirements.
