State officials say a lot less paper making chemical leaked from two train cars that overturned into the Penobscot River in Bucksport than originally estimated. The Department of Environmental Protection says about 100 to 1-thousand gallons spilled. At first officials thought it might be as much at 6-thousand gallons.The Pan Am Railways train was headed to the Verso Paper Mill when four of its cars derailed Friday night. We’re told the chemical that spilled is a form of liquid latex that’s used to help coat paper during production and it’s typically diluted with water.The two tanks with the latex were emptied yesterday.The other two are being drained today.Officials say over the next few days, three of the four train cars will be moved into the river and pulled out by a crane. The fourth will be lifted up the embankment.
