Air Monitoring

The goals of the Air Monitoring Programare: to determine compliance with the ambient air quality standards; provide real-time monitoring of air quality; 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. For more detail about what we do, please explore the options below.

Special Sampling Projects


AirOhio provides near real-time air quality reporting of the monitoring network that is operated and maintained by Ohio EPA and Local Air Agencies working under contract with Ohio EPA. Air quality information is automatically retrieved from air monitors throughout the state and displayed in various reports.

Air Toxics

On Aug. 3, 2006, an amendment of Ohio Revised Code (ORC) 3704.03(F) became effective as a result of Senate Bill 265 of the 126th General Assembly. The amended statute identifies the requirements for reviewing new and modified air contaminant sources with air toxic emissions. Prior to this, Ohio EPA had an "Air Toxics Policy" often referred to as "Option A." The amended statute incorporated the use of Option A into law and also required Ohio EPA to promulgate a list of toxic air contaminants that would fall under this review requirement. On Dec. 1, 2006, Ohio EPA's list of toxic air contaminants became effective in Ohio Administrative Code (OAC) 3745-114-01. Ohio EPA recommended 303 compounds for the toxic air contaminant list based on a review of scientific evidence available. Below you will find information regarding air toxics in general and Ohio EPA's regulation of air toxics.

Air Monitoring Quality Assurance, Data and Reports

Quality Assurance

Ohio EPA Central Office, District Offices and Local Air Agencies all participate in Ohio’s quality assurance program to ensure Ohio is acquiring and distributing quality ambient air monitoring data. Ohio’s quality assurance program conforms to the requirements of 40 CFR Part 58, Appendix A and B and is the means by which Ohio manages the quality of the monitoring information it produces in a systematic, organized manner. It provides a framework for planning, implementing, assessing and reporting work performed by Ohio EPA and our partners and for carrying out required quality assurance and quality control activities. While monitoring organizations themselves perform a variety of quality assurance activities to ensure quality data is being routinely collected, Ohio also has quality assurance auditors that conduct independent quality assurance evaluations for ambient monitoring network activities.
