RIVER FALLS, Wis. (AP) -- A River Falls company is facing $137,000 in potential fines following a trench collapse last year that killed a 19-year-old worker.

The Occupational Safety and Health Administration Five issued five citations this week against Gordy's Pumping Service.

OSHA says the victim and another worker were working in a 6-foot-deep trench in November when one wall caved in. The other worker wasn't hurt.

The agency levied five safety violations, including one for failing to take proper precautions to prevent a trench collapse. Gordy's has 15 business days to comply with the fines, contest the citations or request a conference with OSHA.

A message left with the company was not immediately returned.
