We are a consensus-driven organization focused on assisting air quality agencies and personnel with implementation and technical issues associated with the federal Clean Air Act. AAPCA was created in the fall of 2012 when several states initiated discussions to form an association of state air quality agencies interested in creating a technical forum where ideas, information, and best practices could be shared when meeting our common goal of improving air quality and ensuring environmental protection. Our members work collaboratively on behalf of states and the communities they protect to act as a conduit for and provide feedback to federal regulators on air quality rules that have significant impacts across the entire nation. We invite you to explore this site and connect with AAPCA's members.
