Martin Marietta Materials has applied for a conditional-use permit for
an underground limestone mine and variances for storage of explosive
materials on 480 acres of property in Anderson Township, Ohio. A mining expert witness for Martin Marietta Materials said the company will take various measures to reduce noise and dust pollution created by the proposed
mine. Bob Rysinski, production manager for the Ohio district of Martin Marietta Materials, explained the process of extracting limestone from the mine.
By coating sorting screens and material transfer chutes in urethane, Rysinski said there would be a significant reduction in noise. He said the plant would use a water spray during the crushing and sorting to control dust, as well as a wheel washing system to prevent trucks from transferring dust to public roads.
Tim Mara, a Cincinnati attorney who represents residents near the proposed mine site, challenged the validity of Rysinski's assessment because he could not provide empirical data.
