The majority of states regulate VOCs because the release of these into the environment can, under certain conditions,
contribute to the formation of ground level ozone. Ozone while a good thing in the upper atmosphere is a bad thing at ground level, causing respiratory distress and even death for those members of the population weakened by respiratory illness or age. The Environmental Protection Agency, in conjunction with state agencies throughout the USA, has set ozone standards. It is these standards that are driving states to regulate VOCs in an effort to decrease the high ozone levels.
