U.S. Environmental Protection Agency Region 5 recently cited Companhia Siderurgica Nacional LLC for alleged clean-air violations at the company's Terre Haute, Ind., facility.

Hydrochloric acid is corrosive to the eyes, skin and mucous membranes. Inhalation may cause coughing, hoarseness, inflammation and ulceration of the respiratory tract, and chest pain.

Newly processed stainless steel is pickled, or bathed in hydrochloric acid, to remove its outer layer and improve its corrosion resistance.

EPA alleges CSN emitted more hydrochloric acid from its pickle line than is allowed by federal regulations during a test done in March 2003.

"EPA's mission is to protect public health and the environment," said Acting Regional Administrator Bharat Mathur. "We will take whatever steps are needed to ensure compliance with the Clean Air Act."

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. The company has 30 days from receipt of the notice to meet with EPA to discuss resolving the allegations.
