U.S. Environmental Protection Agency Region 5 has cited United States Steel Corp. for alleged clean-air violations at the company's Gary Works, Gary, Ind.
EPA alleges U.S. Steel modified two hot-metal desulfurization units without getting required permits and lowest-achievable emission rates, increasing sulfur dioxide emissions in an area that does not meet air quality standards. In addition, it failed to obtain required sulfur dioxide reductions from other air-pollution sources to offset its increased sulfur dioxide emissions.
These are preliminary findings of violations. To resolve them, EPA may issue a compliance order, assess an administrative penalty or bring suit against the company.
U.S. Steel has 30 days from receipt of the notice to request a meeting with EPA to discuss the allegations and how to resolve them.
"EPA's mission is to protect public health and the environment," said Region 5 Administrator Thomas V. Skinner. "We will take whatever steps are needed to ensure compliance with the Clean Air Act."
