Assessing the Cost-Effectiveness of Wyoming's CMAQ Unpaved Road Dust Suppression Program, Year 1

The objective of this study is to quantify the benefits of the use of congestion mitigation and air quality (CMAQ) funds to provide Wyoming counties with funding to apply dust suppressants to their unpaved roads. There are several benefits from the use of dust suppressants. There is the environmental benefit of reduced fugitive dust emissions from unpaved roads. Maintenance costs are generally reduced on treated roads since maintenance isn't needed as often and gravel isn't lost as quickly so it doesn't need to be replaced as often. Finally, treated roads generally provide the user with a higher quality road surface with less raveling, loose aggregate and washboards, all of which can contribute to a loss of vehicle control. Both these improvements in road surface quality and the improved visibility that arises from reductions in dust make unpaved roads safer when they are treated. The goal of this project is to determine the value of the reductions in fugitive dust emissions which are realized by using different dust suppressants and application methods in different situations. By determining the benefits realized in different situations, the results of this study will allow for cost - effective allocation of CMAQ funds in the future. On a broader scale, this study will provide information that will allow for more cost-effective use of road dust suppressants in general.
