Aerial Spraying
To spray an approved pesticide over a city, approval must be given by the Department.
Questions may be addressed to the North Dakota Department of Environmental Quality at 701-328-5153, or email Liz Trythall (ektrythall@nd.gov).
The rules pertaining to aerial spraying are contained in Chapter 33.1-15-10 of the North Dakota Air Pollution Control Rules.
-
Establish whether the proposed application is aerial, and if it is, intended to occur over a populated area. Ground fogging or aerial applications over rural areas do not require approval from the Division of Air Quality; only certification and training from the NDSU Extension Office, State Ag Department and/or FAA and the State Aeronautics Board.
-
Spraying must be done by a certified aerial applicator. Certification is through the NDSU Extension Office. Aerial sprayers must also be registered with the FAA and the State Aeronautics Commission.
-
Spraying must be done with ultra low velocity (ULV) spraying equipment. (Very few crop sprayers are so equipped.)
-
Only EPA registered pesticide may be used unless waived by a public health emergency declaration. Chemical pesticides are the most common for mosquitoes. Biological pesticides are common for cankerworms.
-
The applicant must establish a means for notifying the public of when the spraying is to take place, so that at-risk individuals can take precautions.
-
All spraying must be done in accordance with FAA guidelines and follow reasonable procedures to minimize negative environmental impacts. Considerations include, but are not limited to: time of day, day of week, ambient temperature, wind speed/direction and proximity to shorelines and other natural resources.
