Climate advocates said the climate action plans for both companies look similar, and neither is particularly ambitious.

Gov. Eric Holcomb said the sale of U.S. Steel to a Japanese company reflects the need to remain competitive in a global marketplace.

A Northwestern steel plant announced plans to delay relining a blast furnace in Burns Harbor, Indiana. This comes after calls from advocates to abandon its plan to lock in “dirty” steel techniques.

Indiana is a powerhouse for steel manufacturing more than a quarter of all U.S. steel is made here. But the state could lose that title if it doesnt transition to a greener way of making steel. Thats according to a new report by the American Council for an Energy-Efficient Economy and the Citizens Action Coalition of Indiana.

A report by the Indiana Department of Environmental Management this week says U.S. Steel violated its permit when it released excess iron into a Lake Michigan waterway last month, causing it to turn a rusty color.

U.S. Steel Midwest idled the plant in Portage, about 30 miles east of Chicago, as a precaution after it said a wastewater treatment facility experienced “an upset condition” that sent the rusty colored plume containing elevated levels of lead into the Burns Waterway on Sunday.

State and federal environmental agencies are working with U.S. Steel to investigate the cause of the leak and find out if it's harmful.

A federal judge has approved a revised settlement with U.S. Steel, more than four years after one of the steelmaker's Indiana plants discharged wastewater containing a potentially carcinogenic chemical into a Lake Michigan tributary.

A parks advocacy group says U.S. Steel's revised consent decree doesn't ensure protections for Indiana Dunes National Park.

The company reported the release to the Indiana Department of Environmental Management on Wednesday night.
