Private Dust Control

Applying dust suppression/control can reduce the impact of dust created by traffic on gravel roads. The cost to apply dust suppression is covered by the resident, and the fees and charges vary based on the type of suppressant used and the length of application. See the application form for options available. 

There are two intake periods for Private Dust Control: May and August. 

• Typically the spreading begins as weather and road conditions permit.

Residents may choose which suppressant product they want to be applied on the County road at their residence and pay the difference in cost.

At its sole discretion, Lamont County may undertake work on any treated areas to maintain a safe driving surface. Additionally, we cannot guarantee the level of dust suppression as a result of the application of dust suppression products.

Types of Dust Suppression

Calcium Chloride used as a dust suppressant ($700 - minimum 122m; $175 for 30m increments for additional treatment):

• Applied by blending into the surface gravel.
• Combines with water to suppress dust.
• There is no guarantee as to the level of dust suppression or lifespan.
• Contains a rust inhibitor within the solution to reduce impacts to vehicles.

This product is maintained at the discretion of the County, during the current season of the application.

Mineral Oil (MG30/Magnesium Chloride) used as a dust suppressant ($800 - minimum 122m; $200 for 30m increments for additional treatment):

• Repels water off the road surface.
• Does not combine with water. It is not calcium or salt based.
• It is applied as a thin film on the road surface and takes 24-hours to settle. The road is drivable during this time.
• Applied once during the spring, mineral oil can be graded lightly to maintain a good driving surface during the season.
