The U.S. Department of Labor's Occupational Safety and Health Administration has cited Superior Refining Company LLC for failing to control the use and release of highly hazardous chemicals after an explosion and fire injured several employees.
The company faces $83,150 in proposed penalties.
Investigators cited the refinery for eight serious violations of OSHA's process safety management procedures.
"Ensuring the mechanical integrity of critical equipment used during the refinery shutdown operation could have prevented this incident," said OSHA Eau Claire Area Office Director Mark Hysell. "Superior Refining Company LLC has been working cooperatively with OSHA to ensure a comprehensive process safety management program is implemented at the facility before resuming production."
The company has 15 business days from receipt of the citations and penalties to comply, request an informal conference with OSHA's area director, or contest the findings before the independent Occupational Safety and Health Review Commission.
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to help ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance.
