Pipeline leaks oil onto First Nations land near Stoughton, Saskatchewan

A pipeline has leaked 200,000 litres of oil in an aboriginal community near Stoughton in the Saskatchewan province of Canada.

The spill occurred on First Nations land and its cause is yet to be determined.

Once the leakage was discovered, the pipeline was shut down and the oil spill has been completely contained.

The spill spread to 20km radius, reported CBC News.

According to the provincial government, the spill has not affected the quality of air, water, agricultural land or wildlife.

The cleanup of the leakage, led by Calgary-based Tundra Energy Marketing, has led to the recovery of 170,000 litres of oil.

According to Economy Ministry's petroleum and natural gas division assistant deputy minister Doug MacKnight, the area where the leak has occurred, there are several pipelines and until the site is dug up on Wednesday, it will be difficult to ascertain the firm held responsible. However, there are speculations Tundra's pipeline could have leaked.

Tundra was quoted by Reuters as stating that it is cooperating with government and will ensure 'the affected land is restored appropriately'.

Tundra is a privately held unit of Canadian-based grain trading and energy group James Richardson and Sons.

A few months ago, Husky Energy’s pipeline leaked 225,000 litres of oil in a major city at Saskatchewan. This leak impacted the water supply for two cities.

Pipelines enable transport of oil from provinces of Alberta and Saskatchewan to the coastal regions.
