What happened

A mechanical failure in an overfill system released nearly 7,000 litres of diesel outside Qulliq Energy Corporation's power plant in Rankin Inlet. QEC said the spill was contained and began repairing the equipment and remediating affected soil, with heavy machinery operating around the plant. The government-owned utility publicly disclosed the incident on 24 July, nearly a week after the spill. Nunavut's 25 communities depend on local diesel generation, making the territorial utility's power-plant fuel systems critical infrastructure even where electricity supply is not interrupted.
