CMC Granted Air Permit for Arizona Micro Mill

May 13, 2021

Commercial Metals was granted approval for an operating air permit that clears the way for construction of its micro mill in Mesa, Ariz.

“Receiving the air permit is an important milestone in our latest micro mill project, which we have named Arizona 2,” said Tracy Porter, Executive Vice President and Chief Operating Officer. “With the permit in hand, we can now begin construction in preparation for installation of the mill equipment, which we ordered last year. We still anticipate commissioning to occur during the spring of 2023.”

The Mesa micro mill will be the third for Commercial Metals and the second at the Arizona site. It will be the first micro mill capable of producing merchant bar as well as rebar and will use environmentally friendly steelmaking technology.

“The plant’s capability to directly connect to an on-site renewable energy source, a first in North America, will further enhance the low emissions and highly efficient energy consumption of the micro mill process,” said Porter. “We are excited by Arizona 2’s potential and the operational efficiencies, network flexibility, market access and environmental benefits it will provide.”
