State Implementation Plans (SIPs)

State Implementation Plans (SIPs) are comprehensive plans created by individual states in the U.S. to meet federal air quality standards set by the Environmental Protection Agency (EPA). They outline how each state will reduce air pollution from sources like factories, vehicles, and power plants to ensure clean, healthy air for residents. SIPs include specific regulations, programs, and measures tailored to the state's needs. Once approved by the EPA, these plans become legally enforceable and are regularly reviewed to ensure progress toward cleaner air.
