EPA: Plant Trumbull’s most toxic

According to the U.S. Environmental Protection Agency’s annual Toxics Release Inventory issued on Tuesday, Warren Steel Holdings contributed the largest amount of emissions of any organization in the Mahoning Valley.

The company, at 4000 Mahoning Ave. N.A. in Warren, produced 1,062,319 pounds of emissions in 2012. Of that total, 314,788 pounds were released into the air, water or land, while the rest were removed from the plant site.

The EPA reported that zinc (76 percent) was the primary chemical released.

According to the EPA, the top five toxin producers in Trumbull County were Warren Steel Holdings, followed by Niles Power Plant (78, 770 pounds), Arcelormittal Warren (62,130), the General Motors Corp. Lordstown Complex (60,630) and Warren-based Novelis Corp. (57,060).

The EPA reported that a total of 120.1 million pounds of toxins were produced in Ohio during 2012, with Trumbull County accounting for 0.88 percent of the total releases statewide.

“People deserve to know what toxic chemicals are being used and released in their backyards, and what companies are doing to prevent pollution,” EPA Administrator Gina McCarthy said in a prepared statement. “By making that information easily accessible through online tools, maps and reports, TRI is helping protect our health and the environment.”

A request for comment from Warren Steel Holdings was not returned Wednesday.
