At approximately 12:00 p.m. on 2019 Jan. 8, CNL identified a sheen on the water beside a barge being used for PHAI work in Port Hope Harbour. On discovery, absorbent pads were immediately used to remove the sheen, and an absorbent boom was deployed around the barge as a precaution. It was determined that the sheen likely resulted from a very small volume – less than one litre – of hydraulic fluid being washed into the water during barge deck cleaning.
CNL notified the appropriate regulatory agencies, including the Ontario Spills Action Centre and the Canadian Nuclear Safety Commission.
At no time was there a risk to the safety of workers or the public.
