The estimated volume of the leak is 5,000 bbl.

TransCanada is providing updates to state and federal regulators, including the US Pipelines & Hazardous Materials Safety Administration and the National Response Center.

The company expects Keystone to remain shut from Hardisty, Alta., to Cushing, Okla., and Wood River-Patoka, Ill., while response is under way. Keystone MarketLink, between Cushing and the Gulf Coast, continues to operate normally.

Nebraska’s Public Service Commission is scheduled Nov. 20 to release its decision on passage of the system’s Keystone XL expansion through the state.
