Air Monitoring Section

The Air Monitoring Section operates the division’s statewide ambient air monitoring network for the measurement of EPA criteria pollutants- ozone, particulate matter, nitrogen oxides, carbon monoxide and sulfur dioxide, as well as meteorological parameters such as wind speed and direction, temperature, barometric pressure, precipitation and solar radiation.  The air monitoring network includes sampling and analyses for numerous air toxics compounds including many volatile organic compounds such as benzene and 1,3-butdiene, carbonyl compounds such as formaldehyde and acetaldehyde, toxic metals such as lead and arsenic, and semi volatile organic compounds such as naphthalene and benzo (a) pyrene.  Monitoring sites within the network are participants in EPA National Networks such as SLAMS (State and Local Air Monitoring Stations), NCORE (National Core Monitoring Stations), NATTS (National Air Toxics Trends Stations), IMPROVE (Interagency Monitoring of Protected Visual Environments) and CSN/STN (Chemical Speciation Trends Network)


In accordance with federal EPA regulation, 40 CFR Part 58, Subpart B §58.10, the Vermont Air Quality & Climate Division is required to submit to EPA by July 1, 2023, an air monitoring network plan for the State of Vermont. The regulation requires that the plan be posted for public inspection 30 days prior to submission.
