Statement of Policy

It shall be the policy of Scott County to permit the application of dust palliative agents for the control of dust on county rock roads. All pursuant to the provisions of Chapter 319.14 of the Code of Iowa (Obstructions in Highways).

Approved Materials

The following materials are approved for use as a dust control palliative:

  1. Lignosulfonate (Lignin or Tree Sap)*
  2. Calcium Chloride
  3. Magnesium Chloride
WASTE OIL IS NOT PERMITTED AS A DUST CONTROL PALLIATIVE.
The Iowa Department of Natural Resources and the Scott County Health Department will be notified if the use of waste oil is discovered.

Information about the application of Calcium Chloride / Lignosulfonate (Tree Sap) / Glycerin

Calcium Chloride / Tree Sap may be used and reapplied at the discretion of the permit holder depending on the weather. Following application of the dust palliative, grader operators will be instructed to avoid blading the roads until mid October of each year unless potholes develop, then Scott County reserves the right to blade the treated surface as deemed necessary to protect the traveling public.

After dust control materials have been applied the permit holder is responsible for perpetually keeping the area free of chuckholes by filling them with like materials as they develop. Scott County reserves the right to scarify any treated surface portions and to maintain them as rock roads. If in the County's opinion, proper maintenance has not been done by the permit holder, the County will scarify and blade the treated section.

The permit holder is responsible for marking the areas to be treated with signs or flags so that the areas to be prepared are clear to the grader operator. Signs and flags are available at the Scott County Engineer's Office & Secondary Road Maintenance Facility. The permit holders are asked to keep the signs or flags for use in future dust control seasons.
