Inter Pipeline restores Polaris services after leak

(Reuters) - Canada's Inter Pipeline Ltd IPL.TO said on Monday it had restored services to its Polaris pipeline after a leak caused an outage to a part of the system.

The oil pipeline operator said the Alberta Energy Regulator approved the installation of a 400-meter bypass pipeline that enables the western portion of Polaris to transport diluent to customers north of Fort McMurray.

The 865,000-barrel-per-day (bpd) pipeline supplies ultralight oil from Edmonton, Alberta to oil sands sites to be blended with bitumen for transport.

Imperial Oil Ltd IMO.TO, a company majority owned by U.S. major Exxon Mobil Corp XOM.N, said production at its 220,000-bpd Kearl oil sands site had restarted following the return to service of Polaris.

Inter Pipeline detected the leak in its system late last month and reported a spill of 90 cubic meters (566 barrels) of light oil, 80 meters from a wetland and one kilometer from the Clearwater River.

Repair work on the pipeline will continue, while the cause of the leak remains under investigation, Inter Pipeline said. (
