According to DEP North-central Regional Director Nels Taber, the diesel spilled off the well pad and into a neighboring farmer’s field. “Talisman is extremely fortunate that it did not impact surface water or wetlands,” Taber told the press.
The company reported the spill to DEP, but has been unable to explain the cause.
According to the DEP press release, discharging the diesel fuel without a permit violates the Clean Streams Law, and failing to manage the waste properly violates the Solid Waste Management Act.
Cleaning up the spill required the excavation and removal of 3,800 tons of contaminated soil. It also meant collecting some 132,000 gallons of contaminated water - from which 450 gallons of diesel fuel was recovered. You can read the DEP press release here.
