Did you know about Road Salt?
In 2022 York DPW responded to 13 severe winter storm events in addition to the typical daily weather conditions expected throughout the winter season. To help keep our roads safe and drivable last year, York DPW purchased over 4,000 tons of road salt.
Sodium chloride (NaCl), or road salt, remains the most used and most cost-effective material for clearing roads. However, when it’s really cold, sodium chloride loses effectiveness at temperatures below 15 degrees F. Salt used with physical snow removal (plowing) remains the dominant winter snow and ice road treatment method throughout the state of Maine.
Some communities may add sand to help increase traction and prior to 2006, it was standard to treat roads with a salt and sand mix. Since then both MaineDOT and Maine Turnpike Authority have discontinued sand use on state roads for environmental and cost reasons. Sand has no melting properties and washes off the road to fill culverts and impact surface waters, and it can contribute to particulate emissions in urban areas as it is blown. The cost of cleaning up the excess sand in the spring can be high. Therefore, sand use has declined both statewide and nationwide.
