County policy allows residents to apply approved dust suppressing materials to gravel roads. Residents are responsible for all payments to the contractor. There is no charge for the permit.

If you plan to have a dust suppressant applied to the road, please contact an approved contractor immediately. For a list of approved contractors and more information on the county’s dust control policy see “Dust Control” on the website http://www.co.black-hawk.ia.us/222/Dust-Control.
The deadline to sign up is Wednesday, April 12, 2017 unless an earlier deadline is stated by the contractor.
If you have questions, please call the Black Hawk County Engineer’s Office at 319-833-3008.
