Executive Summary: To help guide development in the Canadian Arctic, Indian and Northern Affairs Canada (INAC) developed the Petroleum and Environmental Management Tool (PEMT). The online tool maps the sensitivities of a variety of Arctic features, ranging from whales to traditional harvesting, across the Arctic. The tool is intended to aid government, oil and gas companies, Aboriginal groups, resource managers and public stakeholders in better understanding the geographic distribution of areas which are sensitive for environmental and socio-economic reasons. This document explores two approaches to estimate the relative risk associated with the environmental effects of development activities. It focuses on four Valued Components (VCs): 1. Bowhead whale, 2. Toothed whale, 3. Think-billed murre, 4. Commercial fisheries. Section 2 describes a simple approach for estimating the risk of Project effects. This approach could be adapted, and as appropriate, integrated into the PEMT. Section 3 provides a simple model to estimate the risk of potential cumulative effects. The analyses focus on the offshore areas associated with the Eastern Arctic. It is important to note that the model developed here is not intended to be a full analysis of cumulative effects. Rather, it is intended to be a tool for exploring the potential effects of different development scenarios on different VCs. The results described here suggest that the cumulative effects of development on VCs vary considerably. At one end of the spectrum, bowhead whales are sensitive to development, particularly underwater noise. Relative to routine shipping and drilling activities, seismic operations are expected to contribute the most to cumulative effects. Seabirds such as thick-billed murre can be sensitive to disturbances to their breeding colonies, particularly if aircraft come in very close proximity (although this should generally be avoided as a result of routine flight rules). Compared with bowhead whales, they are much less sensitive to the routine effects of oil and gas development. The commercial turbot fishery falls in between these two extremes. This is a deep water fishery often conducted in depths of 1,000 m or greater. The depth of the fishery in conjunction with the pelagic and migratory nature of turbot reduces the potential for effects on this species from routine oil and gas activities, as well as the potential for cumulative effects. The largest potential for cumulative effects on the commercial turbot fishery is from space conflicts between fishing vessels, and where there is both operating seismic and drill ships. Space conflicts occur when a fishing vessel is unable to access a fishing location due to the presence of either an operating seismic vessel or locations of operating drill ships. The increase in any of the number of fishing vessels, seismic and drilling vessels or all three could potentially lead to increased cumulative effects on the fishery. Overall, the potential for cumulative effects based on the scenarios studied ranged from low to nil. What are the implications for development in the Arctic? Would the development scenario described above put any of the VCs at risk? That question is easiest to answer when there are clear thresholds separating an acceptable environmental effect from one that is not. Thresholds may be ecological (e.g., habitat availability, the viability of a wildlife population), physical (e.g., concentration of contaminants), political (resource management objectives related to a given environmental effect) or social (e.g., acceptable perceived change). Unfortunately, clear thresholds are generally not yet available. For that reason, the analysis is limited to the relative risk of cumulative effects. Despite the limitation, these approaches can be valuable. Both are easy to update as new information becomes available, making them easy to modify and improve. As information on relative importance of environmental effects on a VC (e.g., how probable they are, or how far from a source they extend), the sensitivity of different regions of the Arctic, or thresholds above which environmental effects become problematic becomes available it can easily be incorporated. The model can also be very easily modified to explore and compare the potential effects of different development scenarios. This iterative and exploratory approach could be used to generate discussion on the merits of different development options. It may also focus attention on what information would best contribute to a better understanding of cumulative effects. Both should benefit resource management in the Arctic. (Au)
