There was a release of potentially dangerous sour gas near a small community in northwestern Alberta, RCMP said Friday.

Police said the gas was released Friday afternoon by a plant near Bay Tree about 100 kilometres northwest of Grande Prairie.

First responders and energy industry safety staff determined the gas release happened once and does not pose an ongoing safety or health concern.

Police said they received lots of calls from people wondering if they should leave the area.

Monitoring equipment has not detected any more gas and there is no risk to public safety, RCMP added.

The Alberta Energy Regulator website says sour gas is natural gas that contains measurable amounts of hydrogen sulphide that smells like rotten eggs and is poisonous to humans and animals.
