Wapello County

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.

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

You may obtain the fluorescent lime green flags at Binns & Stevens or at the Secondary Road Department (with proof of application).

Due to weather, road, and traffic conditions, two applications are recommended. A minimum length of 300 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.


Any person desiring to have dust control on a section of road under county jurisdiction shall abide by the following
policies. All persons desiring dust control services in Wapello County shall apply for a dust control permit through a preapproved
contractor by May 1st, 2023. Dust control permit forms will be available from the pre-approved contractors.
Applicants are required to provide all information requested on the permit form and return it to the contractor. There
will be no fee for the Wapello County Dust Control permit. Payment for the dust control treatment will be made directly
to the chosen contractor. Contractors will forward the permit application to the Wapello County Secondary Road
Department for review and approval.

The normal, minimal treatment available will be 300 linear feet with the treatment being applied in one or two separate
applications. Scheduling of these applications will be the responsibility of the resident-selected contractor. Wapello
County will prepare the site prior to the application by the chosen contractor, depending on the need to do so. The dust
control treatment schedule will be an initial treatment placed May 22nd – June 2nd, 2023 and the second treatment
placed July 24th – August 4th, 2023 weather permitting. Wapello County reserves the right to extend these dates
according to weather and road preparation.

Each location treated for dust control shall be marked with 4 fluorescent lime green plastic flags provided by the
contractor and also available at the Wapello County Secondary Road Department (proof of application will be required
to obtain flags at the Secondary Road Department). The flags shall be placed on both sides of the road at each end of
the dust control area and embedded in the road shoulder, at the break of the slope. The flags shall be placed at the time
of permit application. It is the obligation of the applicant to keep all flags in place, marking the limits of the dust control
area for the entire season – failure to do so may result in loss of dust control. Grader operators will be instructed to
avoid blading the marked dust control areas unless potholes over 1” in depth or washboarding develops.

It is the responsibility of the Wapello County Secondary Road Department to maintain the road system in Wapello
County. If the road has deteriorated to the point where its condition constitutes an immediate hazard to traffic in the
judgment of the county Engineer or his designee, it will be bladed immediately, with no compensation to the
resident. In October, the county will prepare the dust control areas for winter, which may include scarifying, blading
and placing additional rock for surfacing.

All questions regarding dust control and material used should be directed to the contractors at the phone number
shown below.

Wapello County will not guarantee the effectiveness of the dust control treatment, and any complaints concerning the
quality will have to be handled between the resident and the contractor they selected.
