US Steel plans to spend $750 million to revitalise its historic Gary, Indiana, mill complex, Kallanish reports.

The minimum $750m will be spent over five years on "... new, state-of-the-art production equipment, machinery, and modernising technology to better serve customers in the automotive, energy, industrial, metal building components, home construction, appliance and container industries," according to a company release.

Initial construction of the Gary mill complex wrapped up in 1908. It was the world's largest steel mill in the early part of the 20th century, and it remains the US' largest integrated mill at 7.5m short tons/year.

The project's funding is recieving a boost from the Indiana Economic Development Corporation, which is offering $10m in tax credits over 10 years, in addition to up to $2m for worker training. The city of Gary is also offering $35m over 25 years in a public-private partnership.

“We are pleased to be making this significant investment at Gary Works, which will improve the facility’s environmental performance, bolster our competitiveness and benefit the local community for years to come,” says US Steel ceo David Burritt. “Through the skill and determination of our employees, support from the state and city, without which this project would not be possible, and favorable trade policies with the strong section 232 national security action on steel imports, we are experiencing a renaissance at US Steel."
