This legislation extends the authorization for appropriations under the Dingell-Johnson Sport Fish Restoration Act, pushing the sunset date from 2026 to 2031. This ensures continued financial support for crucial sport fish restoration and recreational boating safety initiatives. The bill also modifies the funding structure for Interstate Fisheries Commission activities, allowing for a greater allocation based on a percentage of the annual appropriation or a minimum of $200,000. A key provision expands the definition of eligible boating infrastructure projects to include the construction, renovation, or maintenance of alternative fuel facilities for transient nontrailerable recreational vessels. This includes specific definitions for "alternative fuel station facility," "alternative marine fuels," and "drop-in fuels." Furthermore, the bill amends the Internal Revenue Code to significantly reduce the excise tax rate on portable, electronically-aerated bait containers from 10 percent to 3 percent, effective for sales occurring after the Act's enactment.
