Dallas-Fort Worth gets new rules for industrial air pollution, 15 years after the problem was identified
What happened
US environmental regulators are approving Texas's plan to control smog-forming pollution from large industrial sources in the Dallas-Fort Worth area. This means facilities like power plants and factories will need to use updated technology to reduce nitrogen oxide emissions.
Why it matters
The Dallas-Fort Worth area has struggled with ozone pollution for years. This approval means that industrial facilities in the region must finally implement "reasonably available control technology" to cut down on smog. It sets a new baseline for air quality enforcement in a major metropolitan area.
The signal
Watch for the specific emission reduction numbers reported by industrial facilities in Dallas-Fort Worth over the next 12-24 months, and whether local air quality measurements show improvement.
