OLD TOWN, Maine — Officials with the Occupational Safety and Health Administration confirmed they are investigating a fatal incident that happened Tuesday afternoon at the mill in Old Town.

Karen Billups, assistant area director for OSHA, said Tuesday the agency is preparing to start an investigation into an incident at the Expera mill, which was reported about 2:30 p.m. She said OSHA was told one person was killed.

“We are just starting the investigation,” Billups said, declining to say more about what may have happened.

Expera spokeswoman Addie Teeters said in a brief statement Tuesday afternoon that the person involved in the incident was a contractor, not a regular mill employee.

Attempts to reach police, mill and city officials for further information have been unsuccessful.

There have been more than 180 fatal occupational injuries in Maine since 2005, according to Maine Department of Labor statistics. Data do not include the number of fatal injuries in 2014 or to this point in 2015, as the report hasn’t been updated.

The formerly shuttered mill was acquired by Expera Specialty Solutions of Kaukauna, Wisconsin, late last year. The company reopened the former Old Town Fuel & Fiber pulp mill in January and began producing pulp again.

All 180 mill employees were rehired and put back to work by Expera, about six months after they got layoff notices from Old Town Fuel & Fiber.

Old Town police and fire personnel have been joined by a hearse as of 4:30 p.m. at the mill.
