The goals of the Air Monitoring Section are: to determine compliance with the ambient air quality standards; provide real-time monitoring of air pollution episodes; provide data for trend analyses, regulation evaluation and planning; and provide daily information to the public concerning the quality of the air in high-population areas, near major emission sources and in rural areas.

Availability of Draft for Comment– Draft May 2016 Canadian Wildfire Ozone and PM2.5 Exceptional Event Demonstration
The Ohio Environmental Protection Agency (Ohio EPA) is soliciting comments regarding Ohio’s revised Exceptional Event demonstration showing that the plume from the Canadian wildfire which took place in May 2016 near Fort McMurray, Alberta adversely affected ozone and PM2.5 data in a regulatory significant way at several monitors in Ohio such that the data from May 24-25, 2016 should be excluded from regulatory determinations. The Exceptional Events rule applies to data showing an exceedance of a standard which may affect regulatory determinations regarding attainment designation status or other actions by the Administrator. Exclusion of the May 24-25, 2016 data may impact designations for the 2015 ozone standard or have regulatory significance for other actions by the Administrator, including future clean data determinations, redesignations, violations of the 2008 ozone standard, triggers of contingency measures under the 2008 ozone NAAQS, violations the 2015 ozone NAAQS, or violations of the PM2.5 NAAQS.
Ohio EPA will be accepting comments on the draft Exceptional Events demonstration through Wednesday, September 27, 2017. Please see the public notice for information on how to submit comments.
