Parts of Greensburg had to be evacuated again today even as residents were allowed in to retrieve belongings.
Rescuers were working to shore up a slight leak on a 30,000-gallon rail car carrying anhydrous ammonia, a tank damaged in the tornado, said David Sternbenz, an official with the Topeka Fire Department.
While rescuers were working on it, they accidentally broke off a 2-inch valve, causing a serious leak. All incoming traffic into Greensburg has been stopped because of the leak.
They are bringing in a new valve from Dodge City but are trying to intercept the truck with a helicopter to bring the valve in faster.
The car was carrying 14,000 pounds of liquid.
People in the immediate area were evacuated.
