DFW NONATTAINMENT AREA Historical Trend for 8-Hour Ozone Standard Source: NCTCOG Transportation Dept – October 2007 *Attainment Goal - According to the US EPA National Ambient Air Quality Standards, attainment is reached when, at each monitor, the three-year average of the annual fourth-highest daily maximum 8-hour average ozone concentration is less than 85 ppb Consecutive 3-Year Periods Highest Average at any Given Monitor (ppb) Current Standard* < 85 ppb EPA Proposed Standard (between 70 & 75 ppb) 6
