State Implementation Plan (SIP)

The federal Clean Air Act requires each state to develop a State Implementation Plan (SIP) that outlines the state's strategy for controlling air pollution for each of the National Ambient Air Quality Standards (standard). A SIP is a plan that can include a narrative, models, regulations, programs, and other technical documentation that a state presents as evidence of its efforts to address air pollution and maintain good air quality.

The Clean Air Act requires states to involve the general public and industry through public hearings and opportunities to comment on the development of each state plan. States then submit the initial SIP or SIP revision to EPA for approval. Once approved, the SIP is enforceable by the state and EPA.
