Texas air pollution rules now satisfy 'good neighbor' requirements for sulfur dioxide
What happened
US environmental regulators have approved Texas's plan to control air pollution that crosses state lines. This means Texas is now officially compliant with federal clean air rules for sulfur dioxide emissions.
Why it matters
The Clean Air Act requires states to prevent their pollution from harming air quality in other states. This approval means Texas has demonstrated it meets this "good neighbor" provision for sulfur dioxide. It removes a potential point of contention between Texas and downwind states regarding this specific pollutant.
The signal
Watch for any legal challenges from environmental groups or neighboring states that might dispute this approval.
