VOC include any compound of carbon that participates in atmospheric photochemical reactions, excluding:
- Ammonium carbonate
- Carbon dioxide
- Carbon monoxide
- Carbonic acid
- Metallic carbides or carbonates
The compounds that KDHE has designated as having negligible photochemical reactivity are listed within Kansas Administrative Regulation (K.A.R.) 28-19-201(b) (PDF). Emissions of these compounds do not have to be reported as a VOC, although some of these compounds are hazardous air pollutants (HAPs) and must be reported as HAPs.
