desig -- Recommended Area Designations for Revised Federal Ozone Standard
Posted: 08 Sep 2016 09:44:20
On October 1, 2015, the U.S. EPA revised the federal 8-hour average ozone standard, lowering the standard from 0.075 parts per million (ppm) to 0.070 ppm. ARB staff has prepared a Staff Report containing recommendations for area designations and associated boundaries in California based on ambient ozone air quality data monitored from 2013 through 2015. The Staff Report is available at: http://www.arb.ca.gov/desig/8-houroz/8-houroz.htm Additional information regarding federal ozone standard designations can also be found on the same website. California is in a drought emergency. Visit www.SaveOurH2O.org for water conservation tips.
