Summary
The EPA is allowing Montana to stop requiring special oxygenated fuels in Missoula during winter months, since the area now meets clean air standards for carbon monoxide pollution. This change simplifies fuel requirements for gas stations and drivers in the region while maintaining good air quality.
Key Points
- 1Missoula, Montana no longer needs to use special oxygenated gasoline blends in winter to reduce carbon monoxide pollution
- 2The city achieved and maintained clean air quality standards, so the stricter fuel requirement is no longer necessary
- 3Gas stations will have simpler fuel supply chains and potentially lower costs without needing to stock special winter fuel blends
- 4This is a limited maintenance plan, meaning the EPA will monitor air quality for the next 10 years to ensure pollution stays at acceptable levels
- 5If air quality worsens in the future, the oxygenated fuel requirement could be brought back
