Development of Application Rate Guidelines for Winter Storm Management Chemical Additives in Use by ADOT through an Ambient Monitoring System

The application of anti-icing and deicing chemicals by the Arizona Department of Transportation (ADOT) has become one of their most effective winter storm management measures. It is widely known that chemical additives related to winter storm management activities can impact water quality and soil salinity. The primary factors in determining environmental impacts resulting from the use of chemical additives are the type and amount of chemicals used. An increase in the amount of chemical additive applied to a transportation corridor equates to an increased potential for additives in pavement runoff and snowmelt. Yet, the total amount of chemicals used will depend largely on the number and severity of winter storms being managed. Unfortunately, the over-application of the chemical additives can often result in environmental impacts. This research will recommend initial application rate guidelines, implement a winter storm management record keeping system of chemical usage and storm events along transportation corridors, and define how best to evaluate that information to minimize potential environmental impacts. The focus of the research will be to identify trends indicating the accumulation of chemicals along transportation corridors and observed or potential impacts to natural resources associated with these accumulations.
