WHITING, Ind. — BP America Inc. has paid $332,250 in fines after state regulators found more than a dozen safety violations at its oil refinery along Lake Michigan two years ago.

The Indiana Occupational Safety and Health Administration initially announced $384,250 in fines in November 2006, but an agency review board last summer downgraded or dropped half of the 14 original violations and reduced the accompanying fines by $52,000.

BP spokesman Tom Keilman said the company believes it has corrected all of the safety violations found by inspectors. A state report said violations at the 1,700-worker refinery included untested fire hoses, outdated safety procedures and broken equipment.

"We were pleased that BP was able to work with Indiana OSHA to reach a final conclusion to this matter," he said.

The 2006 inspection of the Whiting refinery was prompted by an explosion the year before at BP's refinery near Houston that killed 15 people and injured more than 170. The U.S. Chemical Safety and Hazard Investigation Board found BP fostered bad management at the plant and that company cost-cutting moves were factors in the explosion.

Sean Keefer, deputy commissioner of the Indiana Department of Labor, said the agency and IOSHA were satisfied with BP paying the $332,250 fine and the safety improvements that were made.

"The BP refinery is a safer place to work," he said.

State records show that the hazards identified at the refinery were corrected by July 2007. The settlement between the state and BP was resolved this July and the case closed in October.

BP began construction work in May on a $3.8 billion project to upgrade the 119-year-old refinery to process heavy high-sulfur Canadian crude oil. BP has said the expansion will boost the refinery's production of gasoline, diesel fuel and jet fuel by 15 percent to about 4.7 billion gallons a year.
