Work in the harbour is expected to continue until January or until the weather makes it difficult to continue. The placement of sand, gravel, cobble and rocks in the corners of the turning basin is expected to provide habitat diversity, shelter for various fish species and promote the growth of aquatic plants. In addition, following the remediation phase, the harbour will undergo habitat restoration that includes improved habitat for fish and other species that exist in that region. With the cleanup of the Port Hope Harbour completed, the expectation is that the site will be removed from the Great Lakes Areas of Concern. CNL has provided regular updates to all relevant regulators during the dredging activities at the Port Hope Harbour, and will continue to do so. As the recovered fish were discovered in the sediment dewatering area, CNL staff and contractors are unable to place the fish back into the harbour as this would constitute a safety concern for project staff. These are bottom dwelling fish that were not recovered during previous electrofishing campaigns, and which have remained in the inner harbour.
Dredging activities are carefully monitored for potential impacts that were identified during the Environmental Assessment and additional mitigation measures are put in place as needed.Įarly on in the dredging process, some fish were found in the sediment processing area, mainly identified as catfish. Previous electrofishing campaigns have resulted in over 6,000 fish of varying species being safely removed and relocated to Lake Ontario outside the Inner harbour work area.
This is performed annually to support the dredging activities and ensure that the work is protective of aquatic life. So far, almost 9,000 tonnes of dewatered material has been solidified and transported successfully for long-term storage.ĭe-fishing of the inner harbour is currently underway.
Hydraulic dredging of the sediments is expected to start later this year and the barges will facilitate the transition from an excavator to a dredge pump. Barges are used to assist in this process, particularly to store the dredged material as well as host the dredging equipment during in-water work. The sediment is then dewatered before being transported for storage at the Long-Term Waste Management Facility. This type of dredging facilitates the removal of large objects from the water and is also being used to remove contaminated sediment using a clam shell bucket. The PHAI cleanup of the Port Hope Harbour is well underway, with mechanical dredging of the approach channel and turning basin in progress. Port Granby Long-Term Waste Management Facility.
