Salt vs Brine - towns debate the switch

PORTLAND (WGME) -- There is a piece of legislation up for discussion in Augusta that could impact how roads are treated during snow storms. 

At the center of the debate is how much salt is used on Maine roads in the winter and the environmental impact that salt has on ponds, rivers and streams.

The Maine DOT and the Maine Turnpike Authority use a pretreatment brine.  It's a liquid mix of salt and water which is put on the roads hours before a storm arrives.  It is said to cut down on the use of rock salt and is more environmentally friendly. 

The state has asked towns to incorporate the use of brine as well, but it is a costly change.  Town roads make up abut 80% of the roads in the state.
