The boiler house at at the deactivated Hatfield’s Ferry Power Station near Masontown in Monongahela Township, Greene County, was imploded at about 11 a.m. Friday morning.

The FirstEnergy plant was built in the late 1960s and closed in 2013. The boiler house contained the three power-generating turbines and was the last remaining major structure on site.

The 250-foot tall building fell without incident.

FirstEnergy spokesperson Todd Meyers said the plant is being removed to ready the property for a return to productive economic use, though there are no concrete plans for the site.

The larger and taller structures on the 236-acre site were already demolished this year by the company. Two concrete hyperbolic cooling towers — 500 and 550 feet tall — were imploded June 8. Three emissions stacks — two 700 feet tall and one 540 feet tall — came down March 4.
