|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, Coast Guard 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. Unified Command consists of Canadian Coast Guard, Mowachaht/Muchalaht First Nation, and BC Ministry of Environment and Climate Change Strategies.
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 were 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.
CCG has reissued the Transport Canada National Aerial Surveillance Program (NASP) flight tasking of the area. Upwelling is being monitored via on-water assets and Remotely Piloted Aircraft System (RPAS).
Resolve Marine, the company who completed the Technical Assessment (TA) at the wreck site, arrived in Nootka Sound on April 18, 2021 on the vessel, Atlantic Condor. Hull was scrubbed, hull thickness was measured, and a patch was put in place over a 11 m gash on the starboard side. The Technical Assessment operation was completed on May 4th.
The Technical Assessment found two tanks containing heavy fuel oil, one tank with marine diesel oil, and one tank with mixed oil product on board the vessel. The amount of fuel is estimated to be approximately 147 cubic metres based on the total volume of the tanks, however that amount may be less if the internal tank walls have been compromised.
Resolve Marine Group will use a process called “hot tapping” to reduce the volume of fuel in the tanks. This process involves drilling a hole in the fuel tank from the outside, attaching a valve, and pumping the fuel out of the tank through a hose attached to the valve. Given the nature of the operation, there is a small risk of a larger release of oil. CCG and partners are prepared to address this should it arise, and will continue to be on-site and ready to respond if necessary.
The Atlantic Condor arrived on site on June 15, and bulk oil removal is expected to completed by the end of June.
Daily preventative actions are being taken to contain the immediate threats and prevent long-term impacts to the environment. Large amounts of off-shore boom have been placed to assist with heavy fuel oil containment. South of the wreck site, deflection booming has been set up. Ten Geographic Response Strategies (GRS) are currently implemented across ecologically sensitive areas.

Incident Management Team (IMT): UNIT UPDATES
Summary: In-field operations are using a combination of floating, sub-sea and aerial resources to meet incident objectives. 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 the upwelling of oil are challenges 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 Unified Command 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.
- Modelling frequency will be reduced to once daily and be issued each morning until the end of the week (2021-06-28)
- Providing recommendations for prioritization of GRS removal (2021-06-27)
- DFO marine mammal rescue and Focus Wildlife are preparing for demobilization (2021-06-27)
- Focus Wildlife deployed noise cannon to scare birds near containment boom (2021-06-23)
- One oiled Surf Scoter was observed near the eastern shore of the Zuciarte channel. Capture was attempted but unsuccessful; ongoing monitoring for potential capture was recommended as the effects of oiling will likely be fatal for the bird (2021-06-23)
- Two spill trajectory models are being provided/updated twice daily, one includes booming and one does not. The modelled product was switched from diesel and lube oil to heavy fuel oil(2021-06-21)
- Crews rescued a Hooded Merganser chick on June 18 from the shoreline south of the RoBoom. It was not oiled and was supposed to be transferred to a local rehab centre for care but did not survive due to environmental exposure / separation from its brood (2021-06-21)
