Arkansas gets US environmental regulator approval for its haze reduction plan
What happened
The US environmental regulator is proposing to approve Arkansas' plan to reduce regional haze. This means Arkansas has a path forward to meet federal visibility protection standards for national parks and wilderness areas.
Why it matters
States must submit plans to reduce haze that obscures views in national parks and wilderness areas. This approval means Arkansas' approach to controlling pollution from power plants and other sources is acceptable to federal regulators. It sets a precedent for how other states might structure their own plans to meet these federal requirements.
The signal
Watch for the final approval of Arkansas' plan and how quickly other states with similar pollution sources follow suit.
