EPA determined that the City of East Liverpool, Ohio and the neighboring Borough of Glasgow, Pennsylvania face an imminent and substantial public health endangerment from human inhalation of airborne manganese particles. Bell stores and processes ferrous and nonferrous materials, including manganese, at its raw products storage and material handling facility (Facility) located on the Ohio-Pennsylvania border. The settlement greatly reduces the likelihood that Bell's future manganese emissions will cause or contribute to a public health endangerment from inhaling airborne manganese particles. Under the settlement, Bell will implement a comprehensive package of injunctive relief to accomplish immediate and long-term reductions in fugitive manganese emissions in tandem with fenceline monitoring at the Facility. The injunctive relief includes ceasing the crushing of manganese until Bell installs and operates a baghouse on a crushing operation, installing doors on several of its storage buildings, restrictions on unloading manganese, upgrades to Bell's existing baghouses, and other fugitive dust control measures. The monitoring system provides for Bell conducting daily air sampling to determine the ambient manganese concentrations. When a monitor records manganese levels exceeding certain action levels for specified averaging periods, the consent decree requires Bell to conduct a Root Cause Analysis to determine all equipment or facility processes causing the elevated ambien
