Bill freezes diesel air rules for ten years.

What it does

This bill stops the EPA from making diesel engine air rules stricter for ten years. It keeps the air limits set in 2007 to 2010. The bill also protects three EPA guidance papers from 2025 and 2026. These papers describe how diesel engines can be changed. After ten years, any new rules must give makers five years to get ready. New rules must also weigh how much they cost makers and how they affect their work.

Who it affects

Diesel engine makers and truck makers gain from the freeze. They do not have to spend money on cleaner engines. People near highways, ports, and work sites breathe dirtier air for ten more years.

One thing to notice

The bill locks in old air rules for ten years. The EPA must think about maker costs and profits when it writes new rules after that.
