The Western Kentucky Coal Co.’s Genesis mine in Centertown, Kentucky, issued WARN notices to employees in late December. The company said it planned for a mass layoff and plant closing on February 24. This will affect 250 employees.

The mine produced 2.4 million short tons of coal in 2018, according to the Mine Safety and Health Administration.

The decision comes after parent company Murray Energy filed for Chapter 11 bankruptcy in October.
