US Mine Safety and Health Administration spokesperson Amy Louviere told ILN that 40-year-old Jason Stacey was welding at the Superior Cleaning Plant in Maitland when he died about 9am local time Wednesday. Investigators believe the welding unit caused the electric charge.

State Office of Miners’ Health, Safety and Training spokesperson Leslie Fitzwater added in an ILN interview that the foreman and welder was an employee of Illinois-based independent contractor Mike Dover Corporation.

Stacey, who had 12 years of experience, had worked at the facility for 15 months.

Both agencies have commenced investigations into the cause of the incident, and MSHA District 12 issued a 103(j) order to suspend work until a review can be done.

Neither spokesperson confirmed which mine or mines the facility serves, though Fitzwater did note that the plant was undergoing renovation and not currently processing coal.

Superior Cleaning is owned by Superior Processing.

Stacey’s death is the fourth in West Virginia this year, and the 12th in the US.
