Summary
What This Bill Does
This joint resolution uses the Congressional Review Act to overturn an EPA rule from January 2025 that allowed California to enforce its Omnibus Low NOX Regulation. That regulation set stricter nitrogen oxide (NOX) emission limits for heavy-duty trucks, buses, and nonroad engines such as construction and agricultural equipment, which other states could also adopt.
Who Benefits and How
Diesel engine manufacturers and heavy equipment makers benefit because they avoid the cost of developing engines that meet California's stricter NOX standards. Trucking companies, construction firms, and agricultural operations benefit by continuing to use existing equipment without retrofitting or replacing it. Fossil fuel companies benefit from continued reliance on conventional diesel engines.
Who Bears the Burden and How
Communities near highways, construction sites, and agricultural areas bear increased health burdens from continued higher levels of nitrogen oxide pollution, which contributes to smog and respiratory disease. Clean technology companies that had invested in low-NOX engine technologies lose a mandated market. California and states that adopted its standards lose their ability to enforce these stricter emission controls.
Key Provisions
- Disapproves and nullifies the EPA rule granting California a waiver for the Omnibus Low NOX Regulation (90 Fed. Reg. 643)
- Covers both on-road heavy-duty vehicles and nonroad engines (construction, agricultural equipment)
- Under the Congressional Review Act, the EPA cannot issue a substantially similar rule without future congressional authorization
