Officials are also trying to make it easier for road crews to cut back on salt. Minnesota is a leader here. Since 2016, the state has run a “smart salting” program to train public road crews and private maintenance workers to apply salt without wasting any, helping organizations cut their usage by between 30% and 70% per the state pollution control agency. Minnesota also has policies limiting the deployment of salt on residential streets, like Davenport is trialing. The state’s legislature is now considering a bill that would protect professional salt-appliers and homeowners from legal liability for accidents if they use too little—a factor advocates say has prevented people from using salt sparingly in the past.
