OMAHA, Neb. (AP) — A livestock feed company has agreed to pay $78,000 in penalties related to last year’s collapse of International Nutrition’s Omaha plant that killed two workers.

The Labor Department’s Occupational Health and Safety Administration announced the settlement Wednesday. Originally, regulators had sought nearly $121,000 in penalties.

As part of the agreement, International Nutrition agreed to hire a consultant to ensure the new plant it is building will comply with all OSHA standards. The company makes nutritional products that are added to livestock and poultry feed.

Federal safety investigators determined that overloaded storage bins on the roof of the plant caused the January 2014 collapse, killing 47-year-old David Ball and 53-year-old Keith Everett. Several other workers were injured, and four were trapped in the rubble and had to be rescued by firefighters.
