CLAIRTON, Pa. -- The Latest on a fire at U.S. Steel coke plant (all times local):
U.S. Steel says it has resumed normal operations at its coke plant outside Pittsburgh after fire knocked out an air pollution control system.
The company said in a statement late Monday that it has completed repairs at the Clairton coke plant following a small electrical fire almost 16 hours earlier. U.S. Steel says equipment used to remove sulfur dioxide is now working again.
It was the second fire at the facility in six months. A Christmas Eve fire caused $40 million in damage and significant releases of sulfur dioxide, a pungent byproduct of fossil fuel combustion that can make it hard to breathe.
U.S. Steel says air quality monitors did not detect elevated levels of sulfur dioxide after Monday's mishap.
Health authorities are threatening to shut down U.S. Steel's suburban Pittsburgh coke plant unless it comes into compliance with air emissions standards.
The Allegheny County Health Department issued an emergency order Monday after a fire at the steel producer's coke works in Clairton knocked out equipment used to remove toxic gases.
Health officials say U.S. Steel must submit a plan within 24 hours and achieve compliance with emissions limits for hydrogen sulfide and sulfur dioxide within 20 days.
The health department says air monitors have not detected elevated sulfur dioxide levels from the early-morning fire. Officials say residents should be aware of the potential for elevated levels of the gas but don't yet need to take precautions.
Health officials in western Pennsylvania say a fire at U.S. Steel's Clairton Coke Works has shut down pollution control systems, and residents are being warned about possible elevated levels of sulfur dioxide.
The Allegheny County health department says fire in an electrical breaker panel shortly after 4:30 a.m. Monday shut down three control rooms, and two still down house equipment used to operate pollution controls, including desulfurization.
Officials say the elderly, parents of children and people with respiratory conditions should be aware that elevated levels of sulfur dioxide are possible.
U.S. Steel says it is taking mitigation steps such as replacing coke oven gas with natural gas and flaring while the damage is being repaired.
The same two control rooms were damaged in a $40 million Christmas Eve fire.
