Abstract:
State area designations reflect data from the prior three-year period as compared with the State ambient air quality standard for each pollutant. They are consistent with the designation criteria contained in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof.
The State PM2.5 designations layer is a polygon coverage showing area designations as required under Health and Safety Code section 39608. The designations are consistent with the criteria established in the California Code of Regulations, title 17, sections 70300 through 70306, and Appendices 1 through 3, thereof. There are three possible designation categories: attainment, nonattainment, and unclassified. The State area designations are reviewed annually and approved by the State Air Resources Board.
