The locomotives, which will serve its Edgar Thomson mill and its Clairton coke facility in western Pennsylvania, represent an investment of more than US$2.3 million. They are expected to save 40,000 gallons of diesel annually and reduce airborne particulate matter (PM2.5) emissions by an amount equivalent to taking 7,000 gasoline-powered passenger vehicles off of the road. 

“Mon Valley Works is the first industrial site to deploy this technology to reduce small particulate matter emissions from its locomotive fleet,” said Scott Buckiso, U. S. Steel senior vice president and chief manufacturing officer. 

“Advancing our Best for All strategy means producing solutions that benefit our customers and communities, people and planet. This includes investing in technological advancements at our facilities.”
