DECATUR, Ala. - An industrial plant near Decatur is about to undergo an expansion worth almost $100 million.

BP Amoco Chemical Co. says it will invest $95 million in the factory to improve production of three chemicals used for manufacturing.

Demand for the chemicals is up partly because they are used to produce plastic beer bottles and tire cord, which also are increasing in demand.

The Decatur Industrial Development Board unanimously approved tax abatements for the expansion.

While construction work could help the economy over three years of work, the expansion won't add jobs at the plant.
