The Saskatchewan Environmental Society wants Husky Energy to face provincial fines over a major oil spill last summer that jeopardized the drinking water of thousands of people.
About 225,000 litres of oil spilled last July when ground movement caused a Husky pipeline to leak near Maidstone.
About 40 per cent of the oil made its way into the North Saskatchewan River.
Peter Prebble, an environmental society spokesman, says the company violated provincial law by discharging a substance that could hurt the environment.
The society is urging the province to improve the Pipeline Act by ensuring more frequent inspections, upgrading pipelines near water and improving communication with affected communities if there’s a spill.
The government introduced amendments to the act last week to create new inspection audit powers and raise penalties to as high as $500,000 a day.
