ENVIRONMENT

BIODIVERSITY

We respect the biodiversity of areas surrounding our operations.

Whether within our plants or through our raw material mining operations, U. S. Steel's footprint stretches over a large portion of the countries where we operate. Within that expanse, we operate in a variety of environments that each have different climates, flora, and fauna. It is our responsibility to respect the environments surrounding our operations and maintain their biodiversity. Because each site is unique, we tailor operating procedures and protection plans to minimize the impacts to biodiversity.

  • We consider the impacts on wildlife, including protected species (such as the northern long-eared bat and the Karner blue butterfly) when applying for construction and operating permits.
  • We develop and promote the development of wildlife habitats on and around our facilities.
  • We remediate and restore former U. S. Steel properties, allowing them to be used for new residential, commercial and industrial purposes.

FLIGHT OF THE EAGLET

In July 2024, a young bald eagle named Lucky launched itself from a tree branch into its first flight — thrilling the eaglet’s more than 2 million fans.

Lucky is the most recent star of the eagle family that nests at U. S. Steel’s Mon Valley Works Irvin Plant in West Mifflin, Pennsylvania. Cameras near the nest have provided a live video feed of the family’s activities after the original eagle couple, Claire and Irvin, first took up residence there in 2013. Lucky was the pair’s seventh eaglet to be hatched there.

Lucky — whose name had been picked in a fundraising contest cosponsored by U. S. Steel and the Tamarack Wildlife Center — was 77 days old at the time of that first flight. The event was marked by a spate of media coverage in the Pittsburgh area, calling attention to the plant’s wildlife-protection efforts.
