Federal air quality rules will pause for a California county that met its deadline
What happened
US environmental regulators are proposing to suspend some air quality rules for a county in California. This happens because the county met its deadline for reducing fine particulate matter in the air.
Why it matters
When an area fails to meet federal air quality standards, it faces strict rules to clean up its air. This proposal means a California county will no longer have to follow some of those rules. Local governments and businesses in Plumas County will have less pressure to implement costly pollution controls, even though the area still carries the 'nonattainment' label.
The signal
Watch whether the state of California requests a full redesignation for the area, which would remove the 'nonattainment' label entirely.
