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.

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


Deadline date for signup is April 26th,2024.
Late applications will not get dust control until a later date and will be assessed a $10 fee by the County.

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 the Muscatine Counter Engineer’s Office.

Muscatine County Dust Control Regulations

Permit applications will be accepted by participating contractors and approved by Muscatine County until April 26, 2024. Applications made after April 26, 2024 will be subject to a $10.00 fee.

Dust control is permitted to be applied on a county road under the following conditions:

  • The firm/ contractor applying the dust control must be pre-approved by the Secondary Road Department. WASTE OIL IS NOT PERMITTED FOR DUST CONTROL.
  • The landowner/applicant must fill out a permit to apply a dust control product prior to any application of the product. A permit can be obtained through the contractor you choose. Please complete the necessary information and return the permit to your applicator. The applicator will return the permit to the Secondary Road Department for review and approval.
  • You (the applicant) are responsible for payment to the firm with whom you decide to have dust control and will be responsible for making the beginning and end of the dust control spot with approved signs/markers provided by the contractor.
  • You (the applicant), after dust control materials have been applied, are responsible for perpetually keeping the area free of potholes as they develop by filling them with like materials. Any complaints regarding the performance of the dust control product shall be directed to the contractor, not the County.

DEADLINES: Permit applications are due by April 26, 2024. The signs/markers should be up by May 1. The contractor will apply the product soon after, based on weather conditions. The flags must remain in place until October 15.

The Muscatine County Secondary Road Department has the responsibility to maintain the road system in the County. Following the application of dust control, grader operators will be instructed to avoid as much as possible blading the roads until October unless potholes develop, then Muscatine County reserves the right to blade the treated surface as deemed necessary to protect the traveling public.

Muscatine County reserves the right to scarify any treated surfaces and maintain them as rock roads. Muscatine County may, at any time it deems necessary, add rock, blade the road or revert any dust control to rock. All efforts will be made to save dust control spots; but, if in the opinion of the Department, work needs to be done, it will be done. Also, please note that in October your dust alleviation spot will be graded or rocked as needed for winter preparation.
