Rhode Island must now show how it will clear the air for national parks
What happened
US environmental regulators are approving Rhode Island's plan to reduce haze that affects visibility in national parks. This means the state has a formal strategy to clean up its air, which will be reviewed periodically.
Why it matters
Every state must show how it will improve air quality in national parks and wilderness areas. This document means Rhode Island's plan is now officially on the books. It sets a baseline for future enforcement and progress checks on regional haze.
The signal
Watch for Rhode Island's next progress report to see if the state is actually meeting its haze reduction targets.
