4. Community Feedback
No concerns raised specifically about cumulative effects
Concerns raised that are relevant to the cumulative effects assessment:
Project effects on Inuit land use activities: travel around railway, and harvesting;
Project effects on marine mammals;
Project effects on caribou;

6. Summary of Effects Assessment
VEC/VSEC
Characterization of Residual Effect(s)
Significance Rating
Terrestrial Environment
Majority of biophysical cumulative effects identified are associated with the potential future development scenario
Cumulative effects to wildlife as the result of climate change are not significant
Cumulative effects will occur to vegetation abundance, diversity, and health
Climate change is expected to result in an increase in vegetation biomass
Increased biomass provides minor offsetting effects
Vegetation species composition will change with the expansion of shrub and graminoid coverage due to climate change
Health effects on vegetation associated with dust deposition are not significant
Cumulative effects on vegetation are not significant
Phase 2 Proposal has minor effects on caribou that are manageable by mitigation
Majority of cumulative effects are related to minor contributions to habitat loss or sensory disturbance
Potential future development scenario has the potential to create cumulative effects to caribou
Regional exploration by Baffinland also creates disturbance outside of the PDA
Not significant
Human Environment
Cumulative socio-economic effects are largely positive, with adverse effects associated with the potential future development
Not significant, Significant (positive)
Atmospheric Environment
GHG emissions will contribute incrementally to global climate change
Air quality, noise and vibration, and landforms, soils, and permafrost have localized effects but no significant cumulative effects
Difficult to assess climate change effects
Freshwater Environment
Cumulative effects to water quantity could occur from water withdrawal from expanded camps during potential future development
Cumulative effects to water quality may occur from increased effluent during potential future development
Mitigation for water quantity and water quality to reduce effects
Offsetting measures and design changes will address the cumulative effects of potential future development on freshwater fish habitat
Marine Environment
Cumulative effects to marine ice, water, and sediment quality are not significant
Under the potential future development scenario, cumulative effects will result from ice breaking but are not significant
Ringed seals are affected by ice disturbance during potential future development
Narwhals, beluga, and bowhead whales in offshore Baffin Bay are affected by potential future development
Cumulative effects on Inuit land use from ice breaking and increased regional ship traffic may result from potential future development

9. Technical Recommendation Summary
Technical Recommendation Category
Main Issues
Recommendation IDs
Summary of Response and Discussion Items
Cumulative Effects
Information requested on potential cumulative effects of project alternatives
CIRNAC 18
Such an analysis would be hypothetical, and would not support a meaningful assessment of cumulative effects
Alternatives were evaluated in TSD 01, including their effects
Baffinland will work with CIRNAC to determine approach to consideration of potential cumulative interactions of project alternatives
Information requested on cumulative effects of water crossings
DFO
All crossings, temporary or permanent, will be modelled and designed according to requirements for fish passage. This information and design criteria will reduce potential for cumulative impacts with any other crossing structures on the same waterways.
Confirm that all CEA TCs are considered discussion items. No “Technical Recommendations Summary” slide(s) produced.

10. Technical Recommendation Summary
Technical Recommendation Category
Main Issues
Recommendation IDs
Summary of Response and Discussion Items
Cumulative Effects
Requests additional analysis of cumulative caribou habitat loss
GN 15
A revised CEA has been prepared and includes direct and indirect caribou habitat loss.
Recommendation to expand cumulative effects assessment to include Baffinland’s plans for future development
GN 26
Future development scenarios are not reasonably foreseeable, as per NIRB’s definition; therefore, expansion of CEA not required.
Additional clarity on project and cumulative shipping
PC 03
Additional discussion on the number of types of ships in the area has been provided in an updated CEA.
Additional information on the cumulative effects of wind turbines
QIA 02
Wind turbines have been removed from the Project.
“Revised CEA was to be ready for the technical meetings.”
