The Washington County hazardous materials team responded to a chemical leak Wednesday evening along Low Hill Road (Route 88) in Centerville Borough, near Vestaburg.
Jeff Yates, Washington County public safety director, said a man was transporting old anhydrous ammonia cylinders when they fell over in his truck. Yates said a small amount of the chemical, which turns into gas when it is released into the atmosphere, leaked out. Yates said anhydrous ammonia is a concentrated form of ammonia, and that the cylinders in questions would have been used for farm fertilization purposes.
Yates said the incident happened about 7 p.m. and at no time were neighboring residents at risk.
Yates said the man pulled off Route 88 across from the old Frac Tech Services facility that sits along the Monongahela River, and the incident was not connected to the site.
Route 88 was closed for roughly one hour while crews worked to secure the tanks.
