Initial reports Thursday said only about 1,000 gallons had leaked from one tanker.
David Pidgeon, Norfolk Southern spokesman, estimated that between 3,500 and 4,500 gallons of viscous “heavy” crude oil leaked from four tanker cars after the derailment. Pidgeon said most of the oil ended up in an MSI Corp. parking lot. None of it made it into the Kiski River.
In Thursday’s cold temperatures, the oil congealed soon after hitting the snow and workers were removing the oil and contaminated soil for proper disposal.
