Marine Shipping Regulations Principle pieces of legislation protecting arctic waters: Arctic Waters Pollution
Prevention Act - provides measures to prevent pollution from ships
Canada Shipping Act – makes the owners and/or operators of vessels responsible and liable for their vessels and the consequences of its operations

Key NIRB Issues
Issue (h) – Potential impacts to marine mammals and Inuit harvesting, including movement through the marine environment, resulting from proposed year-round shipping and associated ice breaking, noise and wake effects
Issue (i) – Potential for transboundary impacts associated with proposed shipping activities

Shipping Operations
10 to 12 ore carriers completing 102 round trips every year
Equates to a vessel passing in the shipping lane on average every 1.8 days
Vessels will be approximately 330 meters long, 50 meters wide and 20 meters below water surface when loaded
Vessels can travel at 14.5 knots and 7 knots in open water and ice cover respectively

Typical of Ship Design
Fuel tanks positioned 2 meters from outside edge of ship – greater than regulatory standard
Fuel tanks will be double lined Diesel engines - superior efficiency Noise minimized to improve efficiency and
reduce damage to propeller Ballast treatment – will meet International
and Canadian regulatory standards

Shipping Route

Route Selection Comprehensive Inuit knowledge studies influenced
route selection Designed to avoid traditional resource use areas Designed taking bathymetry and ice conditions into
account Fednav engaged to develop shipping options, decades
of experience in operating ice-breaking bulk carriers in Arctic
Bathymetry program ensures adequate depth for safety

Technical Advantage – Steensby Port
Distance from Deposit No 1 to Steensby is 150km, less than half the distance to Nuvuit
Several alternate rail routes to Steensby considered

Technical Disadvantage – Nuvuit
Construction challenges: unstable ground Additional facilities and
airstrip mid rail stream crossings rock cuts, bridges, tunnels 2 more years to construct –
safety, cost Shallow water (government
depth readings)

Shipping Schedule
The viability of the Project depends on the constant supply of iron ore to overseas markets requiring shipping on a 12 month/ per year basis
FEIS concludes year round shipping will not have significant effects (see below)
Tiered approach to adaptive management Potential for route alteration, vessel speed,
periodic shipping suspensions

Ballast Water Management
BIMC committed to exceeding standards required by Ballast Water Control and Management Regulations
Will conduct both a mid-ocean exchange and use an IMO and Transport Canada approved Ballast Water Treatment System (BWTS)
Ballast water to be exchanged in mid-North Atlantic Ocean, part of same ocean regime as Steensby Port
Exchanged ballast water will then be treated onboard the vessel. Treatment will involve.

Ballast Water Management In response to QIA Technical Review Comments, a comprehensive Ballast
Water Dispersal Modelling report for Steensby Port was commissioned in December 2011 Ballast water will be almost entirely flushed out of Steensby every open
water season Ballast water concentrations are low throughout the port, even where
discharge rates doubled
Ballast water monitoring plan will be developed and incorporated into Environmental Monitoring Program Water surrounding ports: monitor non-native organisms, water
chemistry data, phytoplankton analysis Onboard sampling of residual sediment in ballast tanks

Summary of Predictions
Routine shipping will not have significant negative effects on populations of marine mammals.
The project will not have significant transboundary effects in Nunavik or in Davis Strait (FEIS Volume 9, Section 4.0).
The project will not have significant cumulative effects (FEIS Volume 9, Section 1.4.4) .
Predictions to be verified by monitoring research (discussed later).

This is not a novel situation. Marine mammals are exposed to shipping all over the world. Some examples Bowheads and belugas in the Beaufort
Sea Gray whales along W Coast of North
America Humpback whales off Australia

Bowhead population increased at the rate of 3.4% per year from 1978 to 2001 (Zeh and Punt 2005)
Beluga population stable or probably increasing (Hill and DeMaster 1998)

Gray Whale Population and Shipping
18,000 km round-trip migration During spring migration, northbound
females accompanied by 1-3 month-old calves
During the peak migration periods, approximately 3,000 ships enter and leave ports along route
Population increasing at rate of 2.5%/yr

Industry vs. Whale Population Growth
West Population Seismic – 250,000 km Offshore Wells - 291 Offshore Platforms – 49 Shipping – 5,578 port calls Whale Watching PAX = 46,717 Population Growth = ~12% per year
East Population Seismic – 0 Wells – 0 Platforms – 0 Shipping – 10,850 port calls Whale Watching PAX = 548,974 Population Growth = ~11% per year

Risk of Ship Strikes (1)
The FEIS predicts that there is a very low risk of the ships striking marine mammals
The low risk of a ship strike is because the species of marine mammals in the arctic are known to avoid moving vessels

Risk of Ship Strikes (2)
DFO conducted an analysis of the numbers of whales that could be struck if they took no evasive action when a ship approached
However, all evidence indicates that marine mammals move out of the way of approaching vessels
There is only one situation where there may be a risk of a ship strike

Study Techniques
Aerial Surveys to document changes in mammal numbers and distribution
Hydrophones to document ship noise Directional Arrays to document and
locate mammal calls as ships approach UAVs (unmanned aerial vehicles) to
quietly circle mammals and watch behaviour as ships approach and pass

Program to continue for several years to examine long-term effects and to determine whether habituation will occur
Appropriate statistics will be applied and developed, as necessary
Three season/area/species combinations will be selected for study

Project Activity Mitigation Measure Species
Vessel traffic to/from Steensby Port, including ice management at the dock
• Reduce vessel idling • Minimize footprint of ice disturbance • Reduce vessel speed in ice • Markers along shipping lane in
landfast ice • Vessel designed to limit noise output • Marine mammal observers to be on
select vessels to identify response and behaviours from shipping activities by marine mammals
Ringed Seal, Bearded Seal, Walrus, Beluga, Narwhal, Bowhead Whale
Commence ice breaking activity prior to period of lair and breathing hole creation
Ringed Seal, Bearded Seal
Maintain constant course and speed when possible
