Cold Weather Diesel Reliability Act of 2026
Refreshed 4 h ago
Introduced 2025-11-06Topic: environmentSummary
AI-generated summary, report an errorThis bill would require the Environmental Protection Agency (EPA) to change its Clean Air Act rules within 180 days so that diesel vehicle and engine makers may turn off emissions-related engine slowdowns (derates) or shutdowns when the outside temperature is 20 degrees Fahrenheit or colder. The engine would have to return to normal operation once temperatures rise above 20 degrees. Only the manufacturer, and no other party, could turn off these functions. The bill would also let manufacturers permanently turn off these functions on farm equipment and on vehicles mainly operated north of 59 degrees north latitude. It states that it does not waive compliance with any Clean Air Act emissions standard.
