Although a steel mill is probably the last place you’d expect to be LEED certified, don’t be surprised when you visit Big River. There is indeed a LEED plaque hanging on our wall. In March of 2017, we became the first LEED (Leadership in Energy and Environmental Design) certified steel production facility in the nation thanks to our environmental sustainability efforts and energy efficiency performance. In addition to our mill building, the employee services building and warehouse have also received LEED certification.
