Dust Abatement & Road Stabilization
Bonner County Policy for Application of Dust Abatement Materials - Ordinance 409
When magnesium chloride has been applied, please drive accordingly until it is dry.
Magnesium chloride is water based and can be removed with water pressure.
Dust Control / Road Stabilization Information for Residents
- All three districts began applying magnesium chloride the 3rd week of May
The program includes 250 miles or 64% of County maintained gravel roads. Gravel is stabilized to reduce routine maintenance. This also reduces fugitive dust by 50% to 80%. 100% dust elimination is not feasible.
Product is typically applied by Road & Bridge crews during late May & June. This product MUST last all summer without re-application. Rain over 0.10 inches helps rejuvenate dust control.
Due to budget constraints, roads must have over 100 average daily traffic counts to be considered for the program. Road & Bridge conducts formal traffic counts annually where deemed necessary. That amount of traffic wears down gravel causing a 10-year rehabilitation cycle. Annual dust control cost is about equal to replacement gravel cost. Tax dollars are spent effectively.
County maintained gravel roads not in the program may receive dust control at the expense of private parties. Residents may hire a licensed and bonded contractor to apply dust control. Contractors MUST secure a permit from Road & Bridge prior to applying dust control on County maintained gravel roads.

Road & Bridge cannot be hired to apply dust control for private parties.
Privately maintained roads are NOT eligible for the Road & Bridge dust control program. If Road & Bridge does not plow snow off your road, then we will not apply dust control to your road.
