The US Environmental Protection Agency Region 5 has reached an agreement with Lehigh Cement Co. on alleged clean-air violations at the company’s Portland cement plant at 121 N. First St., Mitchell, Ind.
 
The agreement, which includes a $74,700 penalty, resolves EPA allegations that Lehigh violated national emission standards for hazardous air pollutants for Portland cement plants and its state operating permit by discharging excessive amounts of particulates (dust, soot, ash) from one of its clinker coolers.
