The bill amends the Clean Air Act, impacting air quality monitoring data affected by natural events or human activities to mitigate wildfire risk. It redefines "exceptional event" to include human activities related to wildfire risk mitigation and provides exclusions. It also details the definition of "action to mitigate wildfire risk" and sets requirements for notifications, regional analysis, and transparency. Additionally, it emphasizes the role of wildfire risk mitigation actions in reducing the frequency and magnitude of wildfires. Furthermore, it establishes criteria and procedures for States to petition the exclusion of air quality data influenced by exceptional events or actions to mitigate wildfire risk from certain determinations by the Administrator.
