8 Ozone Alert! Days were called. (8 Ozone Alerts also called in 2001 season)

1-Hour Standard: No exceedances of the 1-hour ozone standard. The Skiatook monitor’s three exceedances in 2000 no longer provide the ‘near-non-attainment’ threat we assumed both last year and this year.

8-Hour Standard: The 8-hour health-based standard for ozone was exceeded on 6 days during the season for 11 separate 8-hour exceedances. Our 3-year design value (the averaged 4th highest 8-hr reading) continues to improve – ending the year with a .087 ppm (.084 ppm standard) Next season, if the Skiatook monitor records levels no higher than those of this (.083 4^th highest) and last year (.084 4^th highest), the Tulsa area could be in full compliance with the new standard.
