EnvironmentHealthcare

Summary

This regulation sets deadlines for states to submit plans showing how they will improve air quality in areas that have failed to meet federal ozone pollution standards. The rule ensures that regions with unhealthy air take action to protect public health, particularly for children, seniors, and people with respiratory conditions.

Key Points

  • 1States must submit air quality improvement plans by specific deadlines for areas that have been reclassified as not meeting federal ozone standards
  • 2The regulation applies to regions where ground-level ozone pollution exceeds safe levels, typically caused by vehicle emissions and industrial activity
  • 3States must show concrete steps they will take, such as reducing emissions from cars and factories, to bring air quality back to healthy levels
  • 4The deadline varies based on how badly each area is polluted, giving severely polluted areas less time to implement solutions
  • 5Failure to submit an acceptable plan or meet requirements can result in federal intervention and stricter pollution controls imposed by the EPA
