Criteria used for dispensing Calcium Chloride on County and Unorganized Township roads for dust control
Roads must have a minimum Annual Average Daily Traffic (AADT) count of 50 cars per day to have chloride applied in front of homes. Medical exemptions for symptoms such as emphysema or asthma are taken into consideration if documentation from a physician can be provided.
Roads that have a AADT count that exceeds 200 cars per day will receive solid dust control. Solid dust control is the continuous application of Calcium Chloride to the road surface. On stretches of road that are not populated, but meet the solid dust control standards, Calcium Chloride will not be applied to the road surface to save on product costs.
