Reactivity Program - VOC Exemptions

This page last reviewed January 26, 2016


The ARB defines "VOC exempt" compounds as those not expected to meaningfully contribute to ozone formation due to their low reactivity in the atmosphere. Obtaining a “VOC exemption” means that the ARB will add the compound to the list of exempt compounds in the VOC definition for the applicable regulation.
