       The 1-Hr Standard is the legal and enforceable EPA standard for ozone and an exceedance occurs at .125 ppm or higher.

       The standard is violated if the average number of 1-Hr exceedances, at any one monitor over a 3-year period of time is greater than one.

       All monitors in the Tulsa area are currently in compliance with the 1-hr ozone standard, with the 3-year average number of exceedances at the Skiatook (1999 2001) equaling exactly one.

The 8-hr Standard for Ozone is violated if the (4th highest 8-hr average)3-year average of at any one monitor exceeds .084 PPM. The Skiatook monitor is currently in violation of the 8-hr standard.

 

 

 

       8 Ozone Alert! Days were called. (15 Ozone Alerts called 2000 season)

       One exceedance of the 1-hour ozone standard the Keystone Monitor on July 26th. Since the Skiatook monitor did not have a 1-hour exceedance this year, the area is once again in compliance with the enforceable NAAQS for ozone. The 2000 season totaled four (4) 1-hour exceedances (3 at Skiatook monitor and 1 at Glenpool)

       The 8-hour health-based and non-enforceable standard for ozone was exceeded on 7 days during the season for a total of 12 separate 8-hour exceedances. (There were 10 days and 15 separate 8-hour exceedances last year)
