Residential Dust Control

When you spread LIQUIDOW™ Liquid Calcium Chloride on unpaved roads, a lot of problems clear up.

*LIQUIDDOW™ – Trademark of Occidental Chemical Corporation.

Dust control is not dust elimination.
Calcium Chloride attracts moisture, and this is what makes it an excellent dust control product. LIQUIDOW™ is produced from natural brine deposits found underground, so it is safe for the environment.

Marion County requires a permit for dust control applications. Binns & Stevens will submit that permit for you.

APPLICATION DEADLINE: April 15th, 2024 and June 15th, 2024 – No Late Applications will be accepted. 
This allows the county time to process the permit applications and prepare the roads for dust control. If you miss the deadline, you will not be able to get dust control this year. 

Due to weather, road, and traffic conditions, two applications are recommended. A minimum length of 400 feet is REQUIRED.


Please have area to be treated clearly flagged and visible at each end for the ENTIRE season (May to October). If flags are not visible, drivers will use their own judgment for location. PLEASE NOTE: All spots will be measured. Any footage flagged over the amount ordered will be billed to the customer. If you are unsure of flag distance and do not want more than ordered, please indicate that on the application.

Flags are available at all Marion County Shops. If flags are not visible, drivers will use their own judgment for location. If you are unsure of the flag distance and do not want more than ordered, please write that in the Special Instructions section of the permit application below.
