NEW CANAAN — Winter is coming and the Department of Public Works and the Board of Selectmen are making preparations to keep roads clear and safe for drivers.

The selectmen approved a request from Public Works last week that would allow for the purchase of up to 13,500 gallons of Liquid Ice-B-Gone from Innovative Surface Solutions and up to 3,000 tons of Mortons Salt for $17,550 and $258,540, respectively.

According to the assistant director of Public Works, the Ice-B-Gone is used as a supplement to salting the roads. The melting agent can be sprayed directly onto the salt itself or onto pavement to prevent ice and snow from bonding and eliminate black ice.

“It kind of increases the temperature range that salt can work at,” Assistant Director Tiger Mann told the board at their Nov. 9 meeting.

The first order of salt will not be placed until a full shed left over from last year is used, Mann said.

“Last year was a bit light,” Mann explained.

Director of Public Works Michael Pastore explained that 2016 saw only 29 inches of snow, as compared with about 60 each of the previous two years.

Mann said the town must purchase, at minimum, 1,500 tons of salt, but in a normal year about twice that amount is used over the course of a winter.
