Black Hawk County Policy on the Application of Fugitive Dust Control Agents

STATEMENT OF POLICY

It shall be the policy of Black Hawk County to allow private and/or commercial application of various fugitive dust control agents to the unpaved secondary roads under the jurisdiction of the Black Hawk County Engineer.

A permit is required pursuant to the provisions of Chapter 319.14 of the Code of Iowa (Obstructions in Highways).
Permit applicants assume the full responsibility for and any liability resulting from this work on a public roadway.

IMPLEMENTATION OF POLICY

Persons desiring to apply these agents shall contact an approved applicator prior to April 15th.

By April 15th the applicator shall provide the County with a list of locations where dust control has been requested for the season. The list shall provide the resident’s name, address, agent to be use, and length of requested application.

The applicator shall provide the County with a current Material Safety Data Sheet (MSDS) for the material to be applied.

The applicator shall provide the County with a Certificate of Insurance conforming to the County’s requirements. A statement of the current requirements is available from the County Engineer’s Office.

The applicator shall provide proper traffic control and signing during and after the application as specified in Attachment #1.

Application of dust suppressant is not allowed on Sundays, Holidays, or between sunset and sunrise.

Upon the County Engineer’s approval the County will issue a permit to the resident who has requested application of an approved dust control agent.

All financial obligation for the cost of dust control is between the resident and the applicator.

Roadbeds will be prepared for dust control by May 15th unless extreme weather, wetness, or frost conditions make this impossible. In that case the county will notify the applicator.

Maintenance Operators are to avoid blading treated sections of road for as long as the road remains in good condition. In many cases dust control can be left undisturbed for the season providing the resident fills any potholes that develop with loose rock from the road. However, if potholes or other deterioration of the treated area reaches the point of being an immediate hazard to traffic, the County, upon the order of the County Engineer or Road Superintendent, will blade and repair the treated area without notice or compensation to the resident. Repair by the county will consist of scarifying the treated area and maintaining it as a granular surfaced road. Maintenance Operators will blade treated sections if they become slippery.

After October 1st the County will resume regular rock road maintenance on treated areas as deemed to be in the best interest of public travel. If a chip seal treated area is determined to be in good enough condition it will not be bladed.
