Authorities continue their efforts to determine what caused the fire that damaged a Lowndes County containerboard mill late Monday night.

Around 11:56 p.m., Lowndes County Fire Rescue and the Valdosta Fire Department were dispatched to Packaging Corporation of America, along with emergency medical services, said Lowndes County Fire Rescue Captain Ken Carter.

An emailed press release from Roger Willis, PCA human resources director, stated that the fire was possibly caused by electrical wiring.

The release also stated that the fire was confined to the ceiling area of the turbine generator room and more would be known after an investigation is complete.

There were no reported injuries. According to the press release, no other damage was reported.

Also, the press release stated that the blaze is not expected to impact PCA’s facility expansion, which broke ground in 2010. T

he project includes a new recovery boiler, which will replace three boilers built in 1953, as well as a turbine generator and paper machine drying efficiency improvements. The new equipment is reportedly pollution-controlled, and a large percentage of it produces self-sustained, green energy.

In a telephone interview Tuesday, Willis said that the incident will not affect the employees working at the mill. The director declined to say how many employees actually worked in the area of the mill that sustained fire damage: “I am not at liberty to say. Everyone is still working. No one is out of a job. We are in the process of making necessary repairs to the wiring, and when completed, we will start up the mill.” Carter said firefighters battled the blaze from 11:56 p.m. Monday until 3:52 a.m. Tuesday.
