In response to Assembly Bill 617 (C. Garcia, Chapter 136, Statutes of 2017), the California Air Resources Board (CARB) established the Community Air Protection Program to reduce exposure in communities most impacted by air pollution. Communities across the State are leading efforts to measure air pollution and develop strategies to reduce emissions in their neighborhood. Community Steering Committees, Community Members, Air Districts, and the California Air Resources Board (CARB) use community boundaries for the development and implementation of the Community Emissions Reduction Plans (CERP) or Community Air Monitoring Plans (CAMP). These community boundaries are developed by the Air Districts in close partnership with their Community Steering Committees.
