Dust control is a method of stabilizing the light materials on the surface of a gravel road.  Once applied, the dust that would normally be generated from passing vehicles is minimized.

Thorhild County residents who live beside county gravel roads are eligible for new and/or maintenance applications of either oil or calcium dust suppression product.  Following the completion of the Application for Dust Control form and a prepayment of the calculated fee, Thorhild County will apply dust control product to the identified road surface.  Please note that the scheduling of this work will be subject to the County's regular dust control program priorities and will be combined with other requests in the same geographical area as much as possible to maximize cost effectiveness.
