As part of U. S. Steel’s commitment to protecting biodiversity, we continued to follow the Biodiversity Management Plan developed in 2022 to manage biodiversity risks and adverse impacts at U. S. Steel’s Big River Steel Works. We are dedicated to respecting protected and conserved areas, and we will continue to manage potential adverse impacts on biodiversity. The plan provides guidance to environmental staff for monitoring our properties and designated mitigation areas to identify risks and ensure that our biodiversity program is effective.

Cleaning Up a River

In Mon Valley, U. S. Steel employees in the SteelSUSTAINABILITY employee resource group used a boat donated by a local marina to remove drums, other debris and miscellaneous garbage from the Monongahela River in front of the Irvin Plant, as part of a larger cleanup event. A total of 22,000 pounds of garbage were collected by all the facilities during the event.

On Track to Save Trees

U. S. Steel’s Big River Steel Works installed 13 miles of steel ties. Using 30,000 steel crossties and 28 sets of steel switch ties instead of wooden ties has saved the harvesting of 9,333 trees. Because trees capture carbon from the atmosphere, preserving those trees translates into 336 metric tons of carbon mitigation per year. Over the roughly century-long lifespan of steel ties, these ties will protect the removal of 33,600 metric tons of carbon from the atmosphere. The ties are made from 100% recycled content, and though their purchase price is slightly higher than wooden ties, steel ties require less labor, as well as less ballast material—a Scope 3 savings.
