The Undersea Cable Protection Act of 2025 prohibits the National Marine Sanctuaries Act from requiring additional authorizations for undersea fiber optic cables that already have federal or state permits. It directly affects cable operators who have obtained licenses, leases, or permits from any federal or state agency for cable installation or maintenance in national marine sanctuaries. The bill prevents the Secretary from blocking or demanding new permits for these cables once they have valid existing authorization. This simplifies regulatory processes by eliminating redundant federal oversight for cables already approved by other agencies.
