Oil from a Husky Energy pipeline has spilled into the North Saskatchewan River upstream from Maidstone.
Ralph Bock of the Environment Ministry says Husky has told government officials between 200 and 250-thousand litres spilled.
Bock says the release has been contained, and Husky has deployed booms near Paynton to capture anything coming downstream.
City officials in North Battleford, which draws its water supply from the North Saskatchewan River downstream from the spill, says they will be taking water samples and monitoring to see if the flow reaches the city
On Thursday, officials announced – through an email release – the breach was reported on a Husky Energy line upstream of Maidstone in the morning.
It says Husky has activated an emergency response team.
Husky says it has shut the line and is working closely with neighbours and municipalities.
There is no information on how much oil has spilled.
