Stack Height and Rain Guard Guidance

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.

Certification of Information Accuracy

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.

Air Quality Impact Evaluation

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.

Frequently Asked Questions

Transfer of Permit Ownership

Transfer of Permit Ownership Procedures

The Air Quality & Climate Division  requires an amendment of an existing Air Pollution Control Permit whenever there is a change in ownership of a facility. The procedures that must be followed in amending the Permit depend on the degree of changes that will occur at the facility as a result of the change in ownership.

Permit Fees

The Air Permitting & Engineering Section of the Air Quality & Climate Division currently assesses permit application fees for issuance of Permits to Construct and Transfers of Permit Ownership.  No permit application fees are assessed for issuance of Permits to Operate unless modifications to the facility are proposed that require a Permit to Construct in which case the Permit to Construct fees then apply.  These fees are set forth in 3 V.S.A. 2822(j)(1)(A).
