Air Quality Standards Implementation Act of 2024

This bill amends the Clean Air Act to change how national air quality standards are implemented and reviewed. It extends the timeline for reviewing air quality standards from 5 to 10 years, requires consideration of economic impacts and feasibility when setting standards, and mandates that the EPA issue implementing regulations and guidance at the same time as new standards. It also gives states more time (up to 3 years) to correct deficiencies before federal plans are imposed, and adds wildfire mitigation measures as factors that can be considered in air quality designations. The bill directly affects states, local governments, and businesses that must comply with air quality regulations, particularly those in ozone and particulate matter nonattainment areas. These changes aim to create a more balanced implementation process that considers both environmental protection and practical economic considerations.
