Propane has leaked from the Irving Oil facility off Pleasant Street in Dartmouth, but a fire official says there's little risk to the public.
The area does smell like propane and there is a plume that's dispersing over Halifax Harbour.
Fire division commander Scott Shaffner said the leak was large at the beginning, but that it's "settled down quite a bit."
"It’s a very small leak now," he said. "They've isolated the issue and the amount coming out posses a very low risk at this point in time.”
The problem was spotted Wednesday morning by workers at the facility and firefighters were called.
