The Environmental Protection Agency (EPA) is proposing to approve West Virginia's plan to address visibility issues caused by air pollution in national parks and wilderness areas, known as Class I areas. This decision reverses a previous proposal to disapprove the state's plan. The approval is based on West Virginia's measures to control emissions and the conclusion that no further actions are needed to improve visibility during the specified period. The EPA's decision reflects a change in their policy, suggesting that if current air conditions are below a certain improvement mark, states are meeting progress requirements.
Simple Explanation
The EPA thinks that West Virginia's plan to make the air clearer around special nature areas is good, even though they first said it wasn't. They changed their mind because they believe the air is getting better, so the plan can stay as it is.
