US steel maker Commercial Metals Company announced that the Maricopa County Air Quality Department on April 23 granted it an operating air permit, enabling the Company to begin construction of its third technologically advanced micro mill, the second at its Mesa in Arizona site. CMC’s Executive Vice President and Chief Operating Officer Tracy Porter said "Receiving the air permit is an important milestone in our latest micro mill project, which we have named Arizona 2. 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."

Porter added "Once completed, Arizona 2 will be the first micro mill in the world to produce merchant bar as well as rebar, and will employ the latest in 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. We are excited by Arizona 2''s potential and the operational efficiencies, network flexibility, market access, and environmental benefits it will provide.”
