FRANKFORT — The harsh winter season has Kentucky officials looking for ways to conserve dwindling salt supplies.
Officials say less than 150,000 tons of salt are on hand with more winter left.
On average, the Transportation Cabinet uses 200,000 to 250,000 tons of salt a year. So far this winter, crews have spread more than 300,000 tons.
As a result, when conditions permit, crews will rely more on plowing and less on treatment with salt.
Officials say salt reserves across Kentucky are dwindling. Even the state's largest reserve, at the Louisville Mega Cavern, has been tapped.
The cabinet started this winter with a 60,000-ton emergency reserve inside Mega Cavern.
As of Friday, the reserve was down to 26,000 tons. And the 12 districts of the Department of Highways had requested 18,000 tons of the reserve to replenish supplies.
