An underground coal refuse fire at the site of a soon-to-be-shuttered glass factory in western Pennsylvania may be spreading, officials said.
Workers said they saw fire shooting up through the ground behind the Pittsburgh Glass Works (PGW) plant in East Deer Township last Thursday.
Two pockets of smoke were visible rising from the ground behind the plant Friday morning, they said.
PGW, the current owner, “discovered visual embers and flame in a small crack in the soil about 30 or 40 yards away from its auto glass production building. The crack was approximately 5 to 6 feet in length and 2 to 3 inches wide,” the company said.
Since last September, the company has been investigating an ongoing fire under the plant caused by coal refuse apparently used as backfill at the site many years ago.
Officials said workers suppressed the flames and are clearing vegetation from the area.
Indoor air quality will be monitored inside the plant, where the company has had to address localized hot spots on the interior concrete floor since last year.
Operations at the 135-year-old automotive glass manufacturing site formerly owned by PPG are to end after this week as production is moved to other sites. PGW has said the Creighton plant is outdated and its manufacturing capacity is above market demand. About 160 remaining employees are to be laid off.
The fire has been investigated by the state Department of Environmental Protection and the federal Occupational Safety and Health Administration, but details on a plan to extinguish the fire haven’t been made public.
Tony Taliani, chairman of the township commissioners, said he is disturbed the fire discovered about 10 months ago is still burning, and said the company hasn’t shared information about its plans for the fire and the site. He said he plans to reengage federal, state and county agencies on the issue. PGW said it would keep employees, neighbors and community leaders updated.
