The bill establishes new authority for qualified cargo and passenger ports in Washington state, emphasizing their role in supporting economic development and trade infrastructure. It recognizes the importance of these ports in coordinating and implementing actions with one another, granting them specific powers related to cargo and passenger transportation while providing immunity from federal antitrust laws. This aims to restore parity between these ports and the marine carrier industry, which already enjoys similar legal protections.

A new section is added to chapter 53.08 RCW, defining "qualified cargo and passenger port" and outlining their powers to collaborate on various operational matters, including rates, rules, and facility management. The section stipulates that these ports can meet and discuss issues of mutual interest, enhancing their ability to operate effectively. Importantly, this new authority is set to expire ten years after its effective date, ensuring a review of its impact and relevance in the future.
