Existing law requires the State Air Resources Board to prepare a statewide strategy to reduce emissions of toxic air contaminants and criteria air pollutants in communities affected by a high cumulative exposure burden that includes an assessment and identification of those communities. Existing law requires the state board, based on the assessment and identification, to select locations around the state for preparation of community emissions reduction programs. Existing law requires the regional air quality management district or the regional air pollution control district encompassing the location selected by the state board, within one year of selection, to adopt a community emissions reduction program to achieve emissions reductions for the location selected using cost-effective measures, as provided.
