Visit our Burning page for more information on how to obtain a burn permit, burning activities, and to learn about our Burn Cleaner, Burn Better campaign.
Dust Control Permit
The department issues dust control (or earthmoving) permits when earthmoving operations disturb an area greater than one tenth of an acre of land (0.1 acre or 4,356 square feet). Earthmoving operations are activities that use any equipment that may generate fugitive dust. Some examples include blasting, cutting and filling, demolition, drilling, excavating, grading, leveling, trenching, and weed abatement by discing or blading.
