FAIRMONT, Neb. (AP) - The owners of a $22 million grain elevator in southern Nebraska where a silo collapsed last month hope to reopen the facility in time for this fall's harvest.

It might take several more weeks for investigators and structural engineers to determine why a silo collapsed at the elevator that opened last March near Fairmont, The Lincoln Journal Star reported (http://bit.ly/1k1dlUd ).

The grain elevator, owned by CPI of Hastings and the Lansing Trade Group of Overland Park, Kan., has seven other silos that appear to be intact.

"The engineers are reviewing it, and we're doing some other testing on the facility," Bob Fifield, of CPI, said. "But as of this time, we believe the rest of it is all safe and secure."

On Jan. 7, employees at the grain elevator noticed a crack forming in one of the 150-foot-tall silos. The silo collapsed, spilling thousands of bushels of grain, before employees could do anything. No one was injured.

Fifield said all the silos are being emptied as a precaution before demolishing the damaged silo. That grain is being moved to the company's other locations, and another company is salvaging the damaged silo's spilled corn by screening out dirt and rubble from the grain.

Fifield said the company has been able to keep all eight employees; five transferred to other CPI locations, three are working in Fairmont.
