Nebraska will be losing 500 jobs with the closing of the Tenneco plant in Cozad, but a company spokeswoman says sales could force production increases at the Seward plant.

On Tuesday, Tenneco said the Cozad shock-absorber plant would close by the end of 2010.

Spokeswoman Jane Ostrander at Tenneco's headquarters in Lake Forest, Ill., said Wednesday that the closing won't affect operations in Lincoln and Seward.

The Lincoln plant makes exhaust systems for Harley-Davidson and has about 100 workers.

She said the Seward plant, with 500 workers, is important for Tenneco's emissions-control business, "and we hope that it will grow with our growing commercial-vehicle business."

Ostrander says there are no specific plans and no timetable.
