Color Coding:
• Monitors in red were operational prior to 2000
• Monitors in blue began operation in 2000
• Monitors in green began operation after 2000
Note: • 2013 values
were updated on September 4 and are subject to change by the end of the ozone season.

DFW Eight-Hour Ozone Regulatory Design Values Current Monitors That Began Operation Before 2000
Monitored regulatory ozone design value (DVR): three-year rolling average of the fourth highest reading per year. Example: The 2012 monitored design value is an average of the fourth highest monitored levels from 2010, 2011, and 2012.
