Air Quality Permit Applications



Delaware state law requires air quality permits for equipment which has the potential to discharge air contaminants into the atmosphere. State regulations (7 DE Admin. Code, 1102) establish permitting procedures and requirements.

The Division of Air Quality suggests that applicants take advantage of a pre-application review process to ensure that final applications are both administratively and technically complete.

The table below lists permit application forms by type and sector. Users should download the forms to their hard drive prior to completing.

Applications should be mailed to the Division of Air Quality, along with required permit fees. All checks should be made payable to: State of Delaware.

Mail Application Forms to:

Division of Air Quality
State Street Commons, Suite 6A
100 West Water Street
Dover, Delaware 19904

Make checks payable to “State of Delaware”

First time applicants must complete an Environmental Permit Application Background Statement. Operators of stationary generators must register their equipment with the Division of Air Quality, regardless of whether that equipment requires a permit to operate. Please submit a separate information form for each generator. There is no fee for this notification form.
