Summary
The EPA has approved Indiana's request to remove the Huntington area from the list of regions that don't meet federal air quality standards for sulfur dioxide pollution. This means the area has improved its air quality enough to meet clean air requirements, and Indiana must now maintain these improvements through an ongoing maintenance plan.
Key Points
- 1Huntington, Indiana is no longer classified as a nonattainment area for sulfur dioxide, meaning the air quality has improved to acceptable federal levels
- 2Indiana must implement a maintenance plan to ensure sulfur dioxide pollution stays at acceptable levels for at least 10 years
- 3The redesignation reflects progress in reducing industrial emissions and improving public health in the Huntington region
- 4If pollution levels rise again in the future, the area could be reclassified as nonattainment, triggering stricter regulations
- 5This change allows the area to face fewer air quality restrictions going forward, assuming the state successfully maintains current pollution levels
