Bill overview
This bill, the LOCOMOTIVES Act, aims to prevent states from creating their own regulations for emissions from existing locomotives and engines. It specifically modifies the Clean Air Act to limit state authority over these types of engines, focusing on those used in commerce, particularly for railroad transportation. The bill seeks to reduce potential barriers to interstate commerce related to locomotive emissions standards. It clarifies the definition of ‘commerce’ to include common carrier railroad transportation.
