Following heavy rain in the week of June 10, a small PHAI workboat tethered in the Port Hope Harbour became submerged with wave action. During work to remove the submerged boat on June 17, approximately 250 mL (about 1 cup) of oil leaked from the motor.
Hydrophobic booms were deployed prior to start of the work to remove the boat. These successfully contained the spill and hydrophobic absorbent pads were used to clean the spill, recovering all the oil.
The pads and boom were disposed of following appropriate handling procedures. The boat was then stored onsite with a spill pool in place to capture any additional leaks. The boat has since been removed from the site.
CNL notified the appropriate regulatory agencies, including the Ontario Spills Action Centre, the Canadian Nuclear Safety Commission, and the Municipality of Port Hope.
