What are the Federal regulations regarding volatile organic compounds (VOCs)?
The EPA has defined “VOC” very broadly. In effect, “any volatile compound of carbon” is classified as a VOC for regulatory purposes, unless specifically exempted. See 40 C.F.R. 51.100 (s). Individual states may have their own VOC definitions, including their own list of exemptions. Although state definitions (including exemptions) are generally the same as the EPA definition, a solvent user should be aware of the precise definition that applies in his or her state.
