State Implementation Plans (SIPs) are a collection of regulations that explain how a State will clean up polluted areas under the Clean Air Act. The states must involve the public in the approval process before a SIP is finalized. USEPA approves each SIP, and if it isn't acceptable, the USEPA can assume responsibility for enforcing the Clean Air Act in that State.

or responsible State Agency for the most up-to-date information.
