CALGARY, Alberta, July 11 (UPI) -- A Canadian energy regulator said it was monitoring the status of oil and natural gas pipelines affected by June flooding in Alberta.
Parts of Alberta were under a state of emergency in June because of a 100-year flood event, which closed most of downtown Calgary for several days.
Canadian pipeline company Enbridge Energy said last week most of its pipeline systems tied to oil operations have returned to service, but at lower operating capacity.
Enbridge closed its Wood Buffalo pipeline system in northeast Alberta in June in response to a spill from its Line 37 pipeline from Fort McMurray.
The NEB said Wednesday it was "actively monitoring the impacts of flooding" to ensure pipelines under its jurisdiction were operating safely.
"Companies with pipelines in areas affected by flooding continue to monitor their systems and take action where appropriate," the regulator said. "There have been reported impacts from the flood involving exposed pipelines caused by erosion or rerouting of waterways."
About 750 barrels of oil spilled from Line 37. Enbridge said no potable water wells were affected by the release though some of the oil spilled into a small creek and a lake.
