Reactivity Program - VOC Exemptions
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.
