Calgary-based Bonterra Energy Corp’s crude oil pipeline ruptured and spilled approximately 10,000 gallons (40,000 liters/250 barrels) of crude oil into Alberta creek, Alberta Energy Regulator said.
According to Alberta Energy Regulator, the spill occurred 14 kilometers (8.7 miles) south of Drayton Valley, Alta last week and the line was shut in and depressurized, and that containment booms were installed. Also regulators said that no impacts to wildlife were reported.
The company said in a news release that it began investigating a problem with the pipeline at 8 a.m. Thursday, and at 1 p.m. it discovered a rupture that was leaking into Washout Creek. The cleanup and recovery is expected to continue for the next three weeks.
As an extra precaution, Bonterra has placed additional booms where the Washout Creek meets the North Saskatchewan River, which is the source of Edmonton's water supply. The company is removing the oil with booms and vacuums, and is mitigating the effect on wildlife by setting up barriers as well as visual deterrents that include having people present.
