Available documents from the Vermont Air Quality and Climate Division:

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.

An Air Quality Impact Evaluation (AQIE) is an evaluation, using approved computer models, of the ambient air quality impacts that the public may be expected to be exposed to due to air pollution emissions from one or more facilities.  The pollutants emitted by the facility, the emission rates, stack parameters (e.g. heights, flow rates, temperature), building parameters, terrain, and meteorology are all taken into account to predict potential ambient impacts caused by the facility.  An AQIE may be conducted for criteria pollutants (e.g. CO, NOx, PM, SO2) or hazardous air contaminants (e.g.
