Port Hope

At approximately 12:20 p.m. on 2022 June 21, a CNL contractor observed an oily substance leaking from a drill head involved in PHAI dredging work in the Port Hope Harbour. The substance was identified as a vegetable-based lubricant used in the drill head.

On discovery, work was stopped and absorbent booms were placed around the oil in the water to contain the spill. Additionally, absorbent pads were used to absorb the oil floating on the surface of the water. The cause of the leak was determined to be a faulty valve that was replaced immediately.

The volume of leaked oil that entered the harbor is estimated to be about 600 millilitres. The oil posed no hazard as it is an environmentally safe vegetable oil-based lubricant. CNL notified the appropriate regulatory agencies, including the Ontario Spills Action Centre and the Canadian Nuclear Safety Commission, as well as the Municipality of Port Hope.

At no time was there a risk to the safety of workers, the public or the environment.
