Apache officials are warning people not to venture west of One Island Lake after a well site was found to be leaking sweet gas.
Dawson Creek RCMP say they have been informed of the sweet gas leak southeast of the city early Wednesday morning.
The leak was at a well site in the Noel file off a resource road and west of One Island Lake.
Police say the leak was found by a water hauler who was working near the site.
They say the leak was determined to have been caused by a failed flange fitting and does not appear to be suspicious.
Sweet gas is different from sour gas in that it does not contain considerable amounts of hydrogen sulphide, which is what makes natural gas toxic.
The company has workers at the site trying to repair the leak but is asking the public to stay away from the area.
Apache officials say the leak should be capped within 12 to 24 hours.
The leak comes just more than one year after a sour gas leak at an Encana well site near Pouce Coupe in November 2009. Encana is currently facing two charges filed by the Ministry of the Environment in relation to the leak.
EnCana is charged with introducing business-related waste into the environment and failing to report a spill of a polluting substance.
