Comparison: State vs. Federal
• Rules. Tennessee's air program is shaped by its state implementation plan (SIP). The SIP is a plan detailing the methods by which the state will implement, maintain, and enforce the National Ambient Air Quality Standards (NAAQS). As mandated by the federal Clean Air Act (CAA), each state must adopt and submit a SIP to the U.S. Environmental Protection Agency (EPA) for approval.
• Administration and enforcement. Tennessee's air program is implemented and enforced by the Tennessee Department of Environment and Conservation's (TDEC) Division of Air Pollution Control. The local air pollution control agencies implement and enforce the air program within their respective jurisdictions.
