The Vermont Air Quality & Climate Division (AQCD) of the Department of Environmental Conservation (DEC) consists of a Permitting & Engineering Section.  In addition to the implementation of the two permitting programs noted below, the Section provides technical and engineering assistance to the AQCD on a broad range of air pollution issues, including estimation and evaluation of criteria, toxic and greenhouse gas emission from stationary sources, evaluation of emission controls and reduction measures for stationary sources, state and federal regulatory interpretation, facility and public outreach, and regulation development.

The AQCD Permitting & Engineering Section implements two permitting programs for the control of air pollution from stationary sources: Permits to Construct, which are required prior to commencing construction or modification of an air pollution emitting facility to ensure necessary emission controls are designed and built into the project from the beginning, and Permits to Operate, which incorporate all air pollution related requirements a facility is subject to and is renewed every 5 years to keep it up-to-date with any new requirements. Both permit programs incorporate the respective federal Clean Air Act permit program requirements for Permits to Construct and Permits to Operate that Vermont is delegated by the U.S. EPA to implement. Thus a facility need only obtain the applicable state air permits and need not obtain separate air permits from the federal U.S. EPA.

Examples of permitted air pollution emitting facilities include: incinerators, boilers for space or process heating, stationary diesel engines such as used for generators or compressors, stationary engines used to generate power from landfills or anaerobic digesters, electric utility power plants, bulk gasoline storage (not including retail gasoline dispensing stations) and industrial processes such as wood furniture manufacturing, spray coating operations, dust generating activities, metal plating operations, plywood and veneer manufacturing, concrete cement batching, hot mix asphalt production, and mineral mining and processing operations such as rock crushing and/or screening operations.  The Vermont Air Pollution Control Regulations Section 5-401 broadly defines those air contaminant sources and respective thresholds, if any, requiring an air permit.

The permit review process is intended to ensure both new and existing emission sources are properly designed and operated with effective emission control measures.  This includes identifying the type of pollution from each emission source, the composition of the pollution, where in the process it may be emitted, what form it may be emitted (e.g. gaseous or particulate), whether it is directly emitted (e.g. dusts, solvents) or chemically formed or altered (e.g. combustion or reaction intermediaries), evaluating emission control and reduction options, calculating the quantities and concentrations of the pollution emitted, evaluating the impacts of those emissions, and writing effective permits to ensure proper emission control and measurable means of ensuring compliance.

Want to check on the application status of a permit?

Information pertaining to the review status of individual permit applications deemed administratively complete after January 1, 2018 may be obtained from the Agency of Natural Resources' Environmental Notice Bulletin. Applications that were deemed administratively complete prior to January 1, 2018 will still be posted to the Agency's old ENB interface.

Need help determining which state permits you may need?

The DEC Environmental Assistance Office provides general permit assistance through Permit Specialists located in the Agency of Natural Resources' (ANR) five regional offices. The Permit Specialist's primary job duty is to serve as the initial state contact for applicants and assist them in identifying all necessary state permits or approvals for any given project. This allows applicants to make informed business decisions about the cost and length of time required to comply with all state regulations. This also increases the likelihood that projects will meet requirements ensuring environmental and public health protection.

Need help applying for an Air Permit?

Guidance for applying for a Construction Permit can be found on our Construction Permit Guidance Page. Some permitting and compliance testing scenarios may require professional assistance from consultants familiar with the regulations and appropriate emission control technologies. A list of consultants can be found  at Air Permitting & Testing Consultants.  An essential reference for determing allowable emissions is the US EPA's Technology Transfer Network Clearinghouse for Inventories & Emissions Factors. You may also find answers to your questions in our Frequently Asked Questions (FAQ). If you have other questions or would like to comment on any of these topics, you may contact the Permitting & Engineering Section Manager via email:  Doug Elliott , Permitting & Engineering Section Chief or phone: (802) 377-5939
