Williams said the DOT has reduced its salt usage by at least 20 percent since the program began nearly a decade ago.
Salem received nearly $200,000 from the state this year to buy two new dump trucks and salt-spreading equipment, Town Manager Keith Hickey said.
“It’s a nice benefit to be able to take advantage of the grants,” he said. “It will allow us to save some money and reduce the effect on the environment. We are happy to participate. “
Two bodies of water particularly vulnerable to salt-contaminated runoff from I-93 are Canobie Lake and Cobbetts Pond.
Derek Monson of Windham, a leader of the Cobbetts Pond Improvement Association, has said the I-93 project has created problems with stormwater runoff.
He said offering grant money to communities and land trusts would be beneficial.
“I think it’s a good start, but there’s a long way to go,” he said. “Every bit helps.”
The deadline to apply for the money is Dec. 13.
