Operational Period
October 23, 2016, 06:30 hours – October 23, 2016, 18:30 hours

Location
Seaforth Channel, approximately 11nm west of Bella Bella

Situation
The Tug Nathan E. Stewart and Barge DBL 55 ran hard aground on the rocks at 10/13/16 (01:13 PDT). The unit was located in Canadian Waters at 52.14.46N, 128.23.160W at the entrance to Seaforth Channel. The tug remains aground on Athlone Island, approximately 11.5 miles from Bella Bella by water. The barge was empty of cargo and was moved to dry dock in Vancouver Harbour. CCG was present when barge arrived and spoke with the barge master, who advised that a minimal amount of fuel was trapped in some of the folded hull. As the vessel was being lifted by the dry dock trace amounts of oil was released. The Port of Vancouver confirmed that there was no recoverable product. The tug is aground in shallow water and is partially submerged. The tug was loaded with 59,924 US gallons of diesel fuel. Kirby was able to confirm that 6554 US gallons of diesel fuel were pumped from the tug into tank 3 port on the barge before the pumps failed due to water in the engine room. A manifest of additional liquids aboard at 90% capacity has been prepared, consisting of the following: 639 US gals lube oil, 550 US gals hydraulic oil, 550 US gals gear oil, 969 US gals dirty bilge.

Reports

SAFETY (as of 08:00 hours, 23/10/16)
• At 14:30 a vessel, not associated with the response, encroached on the dive team within the containment boom and nearly caused an all-stop of operations. The CCGS Bartlett was able to contact the encroaching vessel and ask it to maintain a safe distance. The vessel promptly responded and dive operations were safe to continue.
• Safety protocols remain in place – as stated on previous situation reports.
• Footing issues have been reported at the Bella Bella fuel docks. Personnel are advised to be aware of footing and areas that could cause slips, trips and falls.

FISHERIES CLOSURE
• The fisheries closure for bivalve shellfish fisheries in the Seaforth Channel and Gale Passage remains in place.
• For more information contact: Elysha Gordon 250-756-7192

INCIDENT COMMAND POST
• The ICP continues to operate out of the Heiltsuk Nation Tribal Council chambers.

STAGING AREA
• Staging is available at the Bella Bella fuel dock and at Shearwater.
• On-water staging of equipment has been on barges around the response site

RESPONSE

23/10/16, 06:30 hours – 23/10/16, 18:30 hours
(CURRENT OPERATIONAL PERIOD and SITUATION as of 23/10/16, 08:00 hours)
• The GM Penman and Eagle Bay actively skimmed within the vicinity of the casualty.
• The current buster also skimmed within the vicinity of the casualty, towed by the Strategic TJ and Namgis First Nation landing craft.
• Vessels continued to maintain protective boom within Gale Passage and ensure that debris did not compromise its integrity.
• Helo overflights at 10:00 hours showed the double deflection boom at the mouth of Gale Creek was in place and holding, as well as the primary and secondary containment boom around the casualty.
• NASP overflights at 10:00 and 14:00 hours measured 0.1 litres and 0.3 litres of product around the casualty. No oil sheen was observed in the Gale Creek area and no marine mammals were observed.
• The second NASP overflight at 14:00 hours was cut short due to an engine warning light which forced the air-craft to return to base in Port Hardy to address the issue.
• Divers splashed at 10:00 hours (23/10/16). They inspected the spent lube tank and found that the plumbing above the tank was damaged and the bottom of the tank was open to the seafloor below. It was confirmed that there was no product in the tank. Forward of this tank is the bilge water tank, which was also severely damaged. The plumbing above however was in-tact and required hot-tapping.
• At 13:05 hours dive teams started pumping from the bilge water tank. The content of this tank was confirmed by samplers to be water. Sampling teams were present on the Central Coaster.
• The dive team then moved to the Lube Oil tank and started pumping. By 13:12 the entire tank had been emptied and 1204 litres of a lube oil, sea-water mixture was collected. At 14:37 hours teams started to pump the Hydraulic Oil Tank and completed the task by 15:31. By 15:35 the dive team had started to pump the gear oil tank.
• A small pocket of un-verified petroleum product was released from underneath the deck combing of the Nathan E. Stewart. The pocket of product, which had gone unnoticed during inspection dives, escaped as a result of an accumulation of expelled air from the divers which displaced the product, releasing it to the surface. The product was effectively contained within the primary containment boom and as of 15:30 was collected with sorbent pads.
• An additional layer of 1500’ of kepner boom has not yet been placed around the casualty and will remain as an operational objective for tomorrow’s day-time operational period (24/10/16).
• The CCGS Bartlett maintained its position as on-scene coordinator throughout the day and will trade off with the CCGS Tully at 18:30 hours.
• CCGS Tully remained on stand-by in Bella Bella and prepped for night operations.
• The Bella Bella 1 continued to provide assistance with personnel transfers.

23/10/16, 18:30 hours – 24/10/16, 06:30 hours
(NEXT OPERATIONAL PERIOD)
• The Eagle Bay and GM Penman will remain on scene throughout the evening, monitoring the casualty and surrounding area with the FLIR camera. Both vessels will be prepared to skim if required.
• The Burrard Cleaner #4 and Strategic TJ will tend to the primary and secondary containment boom around the casualty and continue to pick up product with sorbent pads.
• The CCGS Tully will provide on-scene coordination and support to on-water ops.
• The CCGS Bartlett will remain on stand-by and provide communication support to the CCGS Tully.
• The Central Coaster will be moved from the casualty site to Norman Morrison Cove, where it will be prepped for salvage operations.
