Road Salt Additive Pondered

TREMONT — The town is considering an additive to its road salt that would melt ice at temperatures as low as minus-30 degrees.

The rock salt now in use by the town’s snowplow crew does not work at temperatures below 18 degrees, town manager Millard Billings told selectmen Monday.


Another advantage of the additive is that the amount of salt used can be reduced by 30 to 50 percent, which would more than offset the cost of the additive, Mr. Billings said.

Selectmen agreed that the idea was worth exploring. Selectman Chris Eaton, who coordinates Tremont’s snowplowing efforts, said he would talk to the Southwest Harbor public works crew to find out how the additive is working in that town before selectmen make a decision on whether to purchase the additive.
