Merrillville Indiana is a major commercial hub in Lake County — the most heavily industrialized county in Indiana with massive steel, chemical, and oil refinery operations. The BP Whiting refinery — one of the largest refineries in the Midwest — is nearby. Lake County sits within the Emergency Planning Zone of the Cook Nuclear Plant and the Fermi 2 plant in Michigan. The combination of nuclear proximity, refinery operations, and steel manufacturing creates one of the most complex industrial hazard environments in the Midwest.
