Volatile organic compounds (VOCs) are emitted as gases from certain solids or
liquids, and are found in everything from paints and solvents to deodorants and
cosmetics. They are a major concern of EPA and
state air quality boards all over the United States. The Clean Air Act (CAA) is
the law that defines EPA's responsibilities for protecting and improving the
nation's air quality and the stratospheric ozone layer. However, state and local
governments do a majority of the work to meet the Act's requirements, which
includes approving permit applications for industries or chemical processes.
VOCs contribute to the formation of ground-level ozone, which is harmful to
human health and vegetation when present at high enough concentrations. If a
state falls out of compliance with air quality standards set by the federal CAA,
then the state will be required to submit a State Implementation Plan (SIP) for
achieving and maintaining federal air quality standards, including the standard
for ozone. TSG is highly experienced in VOC compliance issues, including
assisting states to meet the requirements outlined in a SIP.
