EPA Cites U.S. Steel For Clean-Air Violations

U.S. Environmental Protection Agency Region 5 has cited U.S. Steel Corp. Great Lakes Division for alleged clean-air violations at the company's steel mill at 1 Quality Drive, Ecorse, Mich.

EPA alleges that U.S. Steel failed to apply for a permit to prevent significant deterioration of air quality for hot metal desulfurization units that it installed in 1985.

EPA said the violations began in 1985 and will continue until the company gets its permit and installs the best available air pollution control technology.

EPA calculates that the company's desulfurization process has resulted in a net increase in sulfur dioxide emissions of at least 57 tons a year.

Companies must get permits that restrict emissions from their plants before they can modify them in ways that increase emissions if the plants are located in areas that already comply with all national outdoor air-quality standards. These permits are designed to prevent deterioration of air quality in areas with clean air.

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 meet with EPA to discuss resolving the allegations.
