Vermont's plan to clear regional haze gets US environmental regulators' approval
What happened
US environmental regulators are proposing to approve Vermont's plan to reduce regional haze. This means Vermont can move forward with its long-term strategy to improve visibility in national parks and wilderness areas.
Why it matters
Every state must submit a plan to clean up regional haze, which is air pollution that obscures views in national parks and wilderness areas. This approval means Vermont's approach meets federal standards for the next decade. It sets a precedent for how other states might structure their own plans to meet these ongoing clean air requirements.
The signal
Watch for similar approvals or rejections of regional haze plans from other states, which will show how strictly US environmental regulators are enforcing these requirements.
