(Adds statement from Imperial Oil)
Sept 14 (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 (NYSE:XOM) XOM.N , said production at its 220,000-bpd Kearl oil sands site had restarted following the return to service of Polaris. 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. work on the pipeline will continue, while the cause of the leak remains under investigation, Inter Pipeline said.
