LCW Deicing Salt Reduction​

Recommended Best Management Practices include:

 

 Anti-icing; apply product before or just as the storm starts. This prevents or weakens the bond of ice to pavement. By being proactive and not reactive, applicators are able to provide safer surfaces sooner, save money and protect the environment. Studies have shown it costs up to 6 times more to melt ice and snow from the top down then bottom up.

​

 Incorporate reduced salt application zones on roads near stream crossings, known vernal pools, wetlands and lakes.

 

 Apply product at the recommended vehicle speed, spreaders are most effective at 25 mph.

 

 Pre-wet or apply a salt-brine, this is a cost-effective anti-icing technique that sticks to the road surface.

 

 Utilize a Road Weather Information System (RWIS) linked to road temperature sensors and on-board monitoring software. By tracking application rates and current real-time weather, applicators can make adjustments and reduce waste.

 

 Insure all applicators (both public employees and private contractors) are trained in proper techniques, calibration and environmental risk assessment. States that have implemented successful road salt reduction strategies have made private applicator certification  through legislation.

 

 Assess chemical alternatives. Some contain higher levels of phosphorus and potentially can lower the dissolved oxygen within waterways causing anoxic conditions.

 

 Insure all applicators have written winter roads management plans that include level of service.

 

 Educate drivers to impact their behavior.

 

The reduction in application of road salt can be achieved without impacting the level of service provided if Best Management Practices are followed. We all would like to see a reduction in costs to our towns and the state, thus a reduction in costs to the public and the increased protection of our natural resources.
