Air Quality

Available documents from the Vermont Air Quality and Climate Division:

Ozone •  PM_2.5 •  Fine/Coarse Speciation •  Carbon Monoxide • Nitrogen Dioxide • Sulfur Dioxide • Carbonyl and VOC •  PAH • BTEX 

The Air Monitoring Section maintains an air-quality monitoring program to measure ozone, nitrogen oxides, carbon monoxide, particulate matter, sulfur dioxide, volatile organic compounds, carbonyls and sulfate. There are monitoring stations in Underhill, Burlington (2/2024 temporary suspended), Rutland, and Bennington. Below is the configuration of Vermont's ambient air monitoring network for 2023.

Vermont Long-Term Monitoring (VLTM) of Acid Sensitive Lakes

The Air Quality & Climate Division (AQCD) requires that emissions from most regulated air pollution sources exhaust through an unobstructed, vertical stack of sufficient height to ensure appropriate upward dispersion of the exhaust, thus minimizing the ground level concentration of air pollutants where individuals may be exposed.

When a Facility submits certain information to the Air Quality & Climate Division, a responsible official of the Facility (see definition below) must attest to its accuracy.  This form is required for Permit Applications, Requests for Transfer of Ownership of a Permitted Facility, Annual Registration Submittals and Annual/Semi-Annual Compliance Reports.
