This joint resolution seeks to overturn an Environmental Protection Agency rule that allows California to set its own pollution control standards for ocean-going vessels while they are docked at ports. Under the Congressional Review Act, Congress can disapprove federal regulations through this process, and if passed, the EPA rule would be eliminated and have no legal effect. The resolution was introduced by six Republican senators and targets a rule that was originally published in the Federal Register in October 2023. The measure affects shipping companies and ports that operate under California's environmental standards, as well as the EPA's authority to defer to state-specific pollution regulations for maritime vessels. No specific funding or implementation timeline is mentioned in the resolution itself, as its sole purpose is to eliminate the existing EPA rule through the congressional disapproval process.
