Environmental Road Salt Application

Environmental Road Salt Application chloride levels were reduced by half when best practices were employed. A recent comprehensive study by environmental researchers at the University of Waterloo and Environment Canada, examined whether the best practices as outlined in Canada’s Road Salt Code of Practice actually delivered the improved environmental outcomes they promised. The answer was… Read more »


Economic costs of poor snowfighting

Economic costs of poor snowfighting According to a Global Insight study: • A one-day major snowstorm can cause a state $300-$700 million in direct and indirect costs. • The economic impact of snow-related closures far exceeds the cost of timely snow removal. • Snow related shutdowns harm hourly workers the worst. Recently, the American Highway… Read more »

Safe Winter Roads Protect Lives

When winter roads become impassable, ambulances, fire engines, police and other emergency vehicles can’t perform their life-saving services. That’s bad enough, but the risk to life and limb goes far beyond the inability to respond to emergencies. More than 116,000 Americans are injured and over 1,300 are killed on snowy, slushy or icy pavement every… Read more »

Minimizing the Environmental Impacts of Deicing

Guelph University Research Review • During certain periods, snowmelt can contain elevated salt levels • Snowmelt runoff from major stormwater outfalls can be collected • Recycling will reduce chloride peaks in the streams without adversely affecting road safety The Salt Institute has long supported research in a broad area of study supporting environmental protection. One… Read more »


Deicing and the Environment

The best salt management practices assure that any negative impacts of using road salt are minimized, while at the same time ensuring the safety and mobility standards required of effective winter maintenance. This includes minimizing the environmental stress road salt can cause. Modern roadways themselves are not a natural feature of the environment and are… Read more »

Safety measures in transportation planning

Safety measures in transportation planning   As the old saying goes, “Failing to plan is planning to fail.” So true. The Federal Highway Administration has a new Primer on Safety Performance Measures for the Transportation Planning Process. This research paper introduces the concept of integrating safety performance measures into the transportation planning process. It outlines… Read more »


People expect clear roads

People expect clear roads The Illinois Policy Institute recently released a report assessing snowfighting effectiveness in Chicago; it is entitled “Ready for the Snow? Gauging Illinois’s performance on a critical core service.” People expect clear roads during wintertime – and they want the roads cleared in a timely fashion. If government fails to meet expectations,… Read more »
