PENN HILLS (KDKA) – Emergency crews were called to Penn Hills for reports of a possible explosion and strange odor Tuesday morning.
According to officials at the scene, residents heard a crackling sound and smelled gas in the area of Althea Road around 10:30 a.m.
Residents initially feared it was coming from a Sunoco pipeline. As it turns out, JetJack was in the process of relining sewers with a polyvinyl substance on nearby Azalea Drive.
During that process, a cloud of smoke usually comes from the ground, which is accompanied by a polyvinyl chloride smell.
Emergency crews responded quickly to the scene, but no evacuations were ordered. The scene was cleared a short time later.
