States get more time to clean up regional haze, again
What happened
US environmental regulators are proposing to push back the deadline for states to submit plans for reducing regional haze. This means states will have an extra two years to develop their strategies for improving visibility in national parks and wilderness areas.
Why it matters
The Clean Air Act requires states to make "reasonable progress" toward natural visibility in national parks and wilderness areas. This rule change means states can delay showing how they will meet those goals. It extends a pattern of pushing back deadlines for environmental compliance, which effectively slows down the pace of air quality improvements.
The signal
Watch for how many states use the full extension period, and whether the new plans actually lead to faster improvements in air quality once they are submitted.
