|Incident:||BLIGH ISLAND SHIPWRECK|
|Incident Start Date||DECEMBER 3, 2020|
|Location:||BLIGH ISLAND, VANCOUVER ISLAND|
|As a result of a number of sightings of sheening and oiling in the vicinity of Bligh Island / Zuciarte Channel, CCG confirms that the shipwreck of the M/V Schiedyk, a 483 ft bulk carrier that sank in 1968, has started to release oil.
The situation escalated between Dec 4-6, and heavy oil was observed on the water and staining rocks on the shoreline. As a result the Canadian Coast Guard (CCG) contracted the Western Canada Marine Response Corporation (WCMRC) to deploy to the area. CCG has established an Incident Command System (ICS) for this incident, with CCG as the Federal Incident Commander in this Unified command alongside BC Ministry of Environment and Climate Change Strategy and the Mowachaht/Muchalaht First Nation.
Remotely operated vehicle (ROV) operations report that the product is seeping from more than one location and that vessel is resting hull-up in 350–400 ft (100 –120 m) of water. M/V Schiedyk was carrying approximately 1000 tons of grain and pulp when it grounded.
Fuel samples have been sent to Environment and Climate Change Canada’s Pacific Environmental Science Center (PESC) and Emergencies Science and Technology Section (ESTS) laboratories from forensic chemistry and fate and behavior modeling. Oil sampling test results indicate oil is similar to historical Bunker “C” type. Rate of oil upwelling is estimated at approximately 1 – 4 L per hour, with an occasional increase to approximately 11 – 13 L per hour due to weather conditions.
Daily preventative actions are being taken to contain the immediate threats and prevent long-term damage to the environment.
The incident public website is updated regularly.
CCG has cancelled the Transport Canada National Aerial Surveillance Program (NASP) flight tasking of the area. Overflights will be scheduled on an as-needed basis going forward. Upwelling is being monitored via Remotely Piloted Aircraft System (RPAS). Drone operations continue. Air Nootka is also conducting daily overflights. DFO’s Speed Air will also conduct overflights three times a week during the technical assessment.
Large amounts off-shore boom has been placed to assist with heavy fuel oil containment. South of the wreck site deflection booming has been set up.
Geographic Response Strategy (GRS) booms have been implemented across ecologically sensitive areas.
DFO Marine Mammal Rescue and Focus Wildlife are on site and have been monitoring and assessing wildlife around Nootka Sound. Impacts to wildlife have been minimal to date.
Resolve Marine Group, the company who is completing the Technical Assessment (TA) at the wreck site, arrived in Nootka Sound on April 18, 2021 on the vessel Atlantic Condor.

Incident Management Team (IMT): UNIT UPDATES
Summary: In-field operations to meet incident objectives are using a combination of floating, sub-sea and aerial resources. These resources provide direction daily, and conduct assignments like Aerial Observation, Protection Booming, Wreck Assessment, surface oil collection and recovery, as well as marine mammal and wildlife assessment. Operations staff are working out of Nootka Sound and Gold River, and following integrated Safety, Communications, and Logistical plans. Planning for these tactical operations is risk-based, and determined through a planning cycle. Equipment such as storage tanks/bins, consumable like Personal Protective Equipment (PPE) and sorbents, as well as additional equipment for contingencies, are stored at the incident staging area near Gold River. Weather, remoteness, and a consistent upwelling of oil continue to challenge in-field operations.

Summary: This incident has challenged the Incident Command Post to find innovative ways to support responders at the remote incident site while also following COVID protocols. CCG and industry have integrated to bolster the existing communication network in the area to ensure responders have a safe and dependable means to communicate with each other and the virtual Incident Command Post. By cascading private/government equipment throughout Western Canada, responders have the on-water pollution counter measure equipment required. The current lack of tourism in the area allows responders to utilize lodging that had been shut down for the off-season.

Environmental Unit (EU): UPDATES
Summary: All measures taken by the Incident Command Post utilize the Precautionary Approach and focused on minimizing damages and maximizing efforts. This approach to incident management relies on the Environmental Unit, which is comprised of Federal, Indigenous, Provincial and industry technical specialists and makes environmental-related recommendations to Unified Command that represents the interests of all contributing Environmental Unit members. An example of an ongoing agenda item for the Environmental Unit is the regular review and update of the ICS 232, a form that documents and prioritizes the Resources at Risk. Operations then use this prioritized list of environmental, economic and cultural sensitivities to build strategies and tactics to prevent damages. These proposed tactics are presented to the Unified Command for approval.
- DFO Marine Mammal team reports 20 Humpback whales spotted going in various directions southwest of Nootka Sound. (2021-04-26)
- Focus Wildlife reports no oiled wildlife observed. Monitoring efforts focused on Zuciarte Channel, the Spanish Pilot Group and the Hanna Channel. Particular focus was given to the east and west shorelines of Zuciarte Channel. Significant aggregations observed today include 200 Western Grebes dispersed south of the entrance to Zuciarte Channel. Also a raft of 10 Common Loons was observed in the Spanish Pilot Group. Observations totaled approximately 500 individuals. (2021-04-25)
