It shall be the policy of Davis County to permit the application of dust control agents for the control of fugitive dust on county gravel roads all pursuant to the provision of Chapter 318.8 of the Code of Iowa.

Certification shall state that the mixture meets or exceeds applicable DNR and EPA regulations. The following materials are approved for use as dust control.

Typical Dust Control Application - The typical dust control treatment will be a minimum of 20 feet wide. The dust control treatment schedule will be an initial treatment placed during the last two weeks of May and the second treatment placed in early August, weather permitting.

Marking Dust Control Area - Each location treated for dust control shall be marked with plastic flags provided by the contractor at no cost to Davis County. 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.

Permit Applications - The Contractor shall accept the dust control permit applications and collect the permit fee from the applicants.

Annual Permit Application - All persons desiring dust control services in Davis County shall apply for a dust control permit through a pre-approved contractor before May 1^st. Permit applications received on or after May 1^st shall be considered late applications. Dust control permit forms will be available from the pre-approved contractors or from Davis County Engineers website. Applicants are required to provide all information requested on the permit form and return it to the contractor accompanied by the permit fee. The contractor will then forward the permit application and fee to the Davis County Secondary Roads Department for review and approval.

Annual Permit for 2 treatments received before May 1^st:	$20.00
Annual Permit for 2 treatments received on or after May 1^st but before the completion of the first application date:	$45.00
Annual Permit received after the first application date, 1 treatment:	$20.00

If more than two (2) treatments are desired the County Highway Department must be notified and there will be a $20.00 fee for each additional treatment.

Dust Control Application - Application dates will be supplied to all contractors by February 1^st each calendar year by the Davis County Engineer's office. This schedule is designed to allow the secondary road crews adequate time to prepare the roadbed to the proper crown and grade by blading the road, and if necessary, adding rock. Residents should be aware that the dust control area may be bladed prior to the second treatment, if necessary, by the secondary road department.

Obligations of Applicant - It is the obligation of the applicant to keep all of the flags up marking the limits of the dust control area for the entire season. Grader operators will be instructed to avoid blading the marked dust control areas unless potholes over 1" in depth or washboarding develop.
