3:50 p.m.

A Wisconsin milling company is disputing federal labor officials’ decision to levy a $1.8 million fine in connection with a fatal plant explosion.

The Didion Milling Co. plant in Cambria exploded on May 31. Five workers died. The Occupational Safety and Health Administration announced Friday that a preventable accumulation of grain dust probably caused the explosion and proposed fining the company $1.8 million.

Didion has 15 days to comply to challenge the fine. Company officials issued a statement Friday saying they don’t agree with OSHA’s conclusions or the penalty’s severity. They say they’re working with their attorneys to determine how to proceed.

They added they plan to build a new plant with state-of-the-art safety systems.

Federal labor officials say a Wisconsin milling company should pay $1.8 million in fines for failing to prevent a fatal plant explosion earlier this year.

The Didion Milling Co. plant in Cambria exploded on May 31. Five workers were killed.

The Occupational Safety and Health Administration issued a news release Friday saying that an accumulation of highly combustible grain dust likely caused the explosion. OSHA officials said the explosion was preventable and proposed $1.84 million in fines.

The company has 15 days to comply with the fine, request a conference with OSHA officials or contest the findings before the Occupational Safety and Health Review Commission.

A Didion spokeswoman didn’t immediately reply to an email seeking comment.
