Oilsands Spill: Imperial Fined $120K for Wastewater Overflow
12 Jun
Summary
- Imperial Oil fined $120,000 for a nearly 5.2 million litre wastewater spill.
- Sensors failed to account for sediment, causing the overflow incident.
- Indigenous communities expressed outrage over the spill and fines.
Imperial Oil faced a $120,000 penalty after a substantial overflow of nearly 5.2 million litres of oilsands wastewater occurred in early 2023 from its Kearl Lake facility. The company pleaded guilty to unauthorized release of industrial wastewater. The incident, which began around January 30, 2023, and lasted 24 hours, resulted in the wastewater freezing on the ground, not entering nearby tributaries like the Firebag River.
The overflow was attributed to a sensor system that did not accurately measure liquid levels due to accumulated sediment over years. This led to confusion regarding actual water levels in the storage pond. Imperial Oil stated that no water entered rivers and there were no adverse impacts on wildlife, while also noting past fines for separate spills at the same site.
Downstream Indigenous communities voiced strong dissatisfaction with the penalty, advocating for harsher consequences for corporate leadership. In response to the 2023 incident, Imperial Oil has invested approximately $2 million in remediation and system improvements, including upgraded alarms and automatic pump activation. A significant portion of the fine, $118,000, will fund environmental projects.
