LOCOMOTIVES Act

This bill (S 1779, the LOCOMOTIVES Act) amends the Clean Air Act to prevent states from setting their own emissions standards for locomotives and engines used in locomotives. It specifically removes exemptions for smaller nonroad engines and clarifies that all locomotives engaged in commercial railroad transportation (as defined by federal law) fall under federal emissions regulations, not state rules. The key provision eliminates state authority over emissions standards for locomotives used in commerce, making federal EPA regulations the exclusive standard. This directly affects railroad companies operating locomotives and the Environmental Protection Agency, which would enforce the uniform federal standards.
