The Environmental Protection Agency (EPA) has approved parts of California's plan to meet air quality standards in the Coachella Valley for ozone levels set in 1997. They approved demonstrations showing reasonable progress and efforts to offset vehicle emissions. The decision follows public comments and reviews of the plan, confirming the approach is scientifically valid and doesn't delay attainment of air quality goals. The action is consistent with the Clean Air Act and doesn't add new requirements beyond those already established by California law.
Simple Explanation
The EPA is happy with how California is trying to make the air cleaner in the Coachella Valley by reducing smog, especially from cars, and says they are doing a good job following the rules from a while ago.
