30 • August 2018 NEWS SCOPE CEMENT The top 20 crushed stone producers accounted for 743 million metric tons, or 55 percent of 2016 U.S. output, according to a report U.S. Geo- logical Survey Commodity Specialist Jason Willet prepared from the most current shipment data available. He also finds that the top 100 operators' limestone and granite production totaled 1.02 billion mt, or 75 percent of 2016 industry shipments. The 294 leading companies in his survey, representing 20 percent of operators tracked, were responsible for 1.21 billion mt or 89 percent of output that year. Topping the list of 2016 crushed stone producers are Vulcan Materials Co., Martin Marietta Materials, Oldcastle Materials, Lehigh Hanson Inc. and LafargeHolcim, followed by Cemex USA, Rogers Group, Carmeuse Lime & Stone, Luck Stone and Lhoist North America. Three producers rounding out the top 20 are now part of larger peers: CRH/Oldcastle acquired Ash Grove Cement (12) and Mulzer Crushed Stone (20) in Spring 2017 and 2018 deals, while Martin Marietta closed on Bluegrass Materials (13) earlier this year. Lehigh maps four-year, $600M master plan for Indiana mill The most ambitious capital undertaking in the 11-year history of Lehigh Hanson Inc. entails a four-year, $600 million-plus moderniza- tion and expansion of the Lehigh Cement Co. Mitchell plant, aimed at increasing capacity from present 660,000-metric ton/year level; lowering energy usage and emissions per ton of finished cement; and, continuing to leverage the southern Indiana site's limestone riches. "The modernization of the Mitchell plant will enable us to pro- duce cement more efficiently and sustainably through the use of state-of-the-art technology and the latest in environmental controls and systems," says Lehigh Hanson CEO Jon Morrish. "The capabilities of the new plant will enable us to better serve our existing customer base in the Midwest while also expanding our reach in this growing market." Lehigh Hanson anticipates a mid-2019 completion of a per- mitting process with the Indiana Department of Environmental Management, leading into a 2020-2022 construction schedule. The producer has worked with local and state officials in recent years to develop additional infrastructure surrounding the mill, topped by a road connecting the property to Indiana Route 37—alleviating truck congestion in the center of town. Overall logistics will change as part of the modernization to accommodate additional rail activity supporting increased cement shipments. The Mitchell plant is strategic to Great Lakes and Ohio River Valley markets. TOP 20 STONE PRODUCERS
