Executive Summary: This report accompanies a GIS-based decision support tool and database that are intended to facilitate the Strategic Environmental Assessment (SEA) of oil and gas leasing options for a portion of the Beaufort Sea. These products were produced for the Department of Indian and Northern Affairs Canada (INAC) - Northern Oil and Gas Branch (NOGB) to aid the NOGB in meeting their commitments associated with management of oil and gas resources on federal land and the provision of hydrocarbon development opportunities in the North, while ensuring environmental protection. The SEA will assist managers and decision-makers in choosing appropriate processes and actions to responsibly manage the opening of offshore areas petroleum industry activities. The study area and analytical resolution was defined using the oil and gas leasing grid within the Beaufort Sea. The study area has been the scene of oil and gas exploration activity since 1957. Oil was first discovered at Atkinson Point in 1969 and major gas fields in the early 1970s. Such finds spurred the proposal of the Mackenzie Valley Pipeline in 1974 and the addition of exploration and investment offshore. Exploration and drilling continued both onshore and offshore until the mid 1970s with the release of the Berger Report, which recommended a 10-year moratorium on the construction of the pipeline. After the release of the Berger Report, the pace of onshore activity declined but offshore exploration escalated in the 1980s. Offshore exploration was facilitated with innovative operating techniques and new offshore platforms that extended the ability to operate in the short open-water season and ice. With the minor exception of the small onshore gas field at Ikhil, no oil or gas has been commercially produced in the area. The preparation of the GIS-based decision-support tool for the study area required the completion of a series of inter-related steps. The steps included: 1. identification and review of potential and final valued ecosystem components (VEC) and valued socio-economic components (VSEC); 2. the review of past, present and potential oil and gas development activities in the region, and the residual effects of these activities; 3. the preparation of sensitivity layers for the VEC and VSEC; 4. the preparation of the geo-economic layer; and 5. the development of decision-rules around the sensitivity layers. A key aspect of the decision-support tool development was the selection of Valued Ecosystem Components (VECs) and Valued Socio-Economic Components (VSECs). Following a review of selected literature, Community Conservation Plans, the VECs chosen for this project include polar bear, beluga whale, ringed seal and migratory birds. When choosing the particular VECs, the project team identified species at risk or species that had high ecological, social, cultural or economic value. All the VECs selected also play an important social, cultural and economic role for the Inuvialuit Settlement Region (ISR) communities, which include Aklavik, Inuvik, Tuktoyaktuk, Ulukhaktok, Sachs Harbour, and Paulatuk. The hunting and trapping of polar bears, beluga whales, ringed seals and migratory birds were identified as the crucial socio-economic and cultural component. To sustainably manage their resources, the Inuvialuit communities designated special areas and recommended land use practices in their community conservation plans (CCPs), depending on the significance and sensitivity of cultural or renewable resources. The VSEC of hunting was selected to be included in the decision support tool because the activity of hunting and the species hunted are susceptible to changes in association with oil and gas activities. The CCPs were used as the basis of the VSEC sensitivity scores. The geo-economic layer components of the deci sion-support tool were based on an INAC-developed scorecard rating system for each grid cell in the study area. Each grid cell was scored based on geological factors, economic factors, and uncertainty. The sensitivity layers are a composite of various pieces of relevant ecosystem (habitat use and availability) and socio-economic information. In their compiled state, they form a sensitivity layer. In some situations there was an intersection of more than one sensitivity rating within a single grid cell. Decision rules were developed to assign the overall sensitivity rating for those grid cells. The rules allow for various levels of conservativeness to be considered related to the sensitivity ratings for a grid cell. Three decision rules were applied in calculating a grid rating, (grid assigned maximum score of scores present, grid assigned mean score of scores present, and grid assigned max value of scores present if 90% of the area of the grid is covered by the max score). This report presents the most conservative scores for the grids. The ability to compare conservativeness is embedded within the decision support tool options. A sensitivity map was developed for each VEC and VSEC. The sensitivity scores provide a relative appreciation of the biological (highlights the most vulnerable and sensitive areas, seasonal distribution, and provides information on the potential response to change resulting from hydrocarbon development), social or economic values within grid. This information can be used by INAC-NOGB as well as other users to manage activities within that grid by providing a better understanding of the sensitive areas within a region. Management options to be applied by NOGB are yet to be determined. The Strategic Environmental Assessment process that is to be undertaken by the Branch will involve the development of leasing management options. This decision-support tool has been designed to eventually support the inclusion of more VECs and VSECs as the geographic information becomes available. The tool could also be used to evaluate potential cumulative effects resulting from oil and gas activity in the region at a strategic level. Preliminary work was completed on a summary of residual effects associated with offshore oil and gas activity (effects that persist after the application of mitigation) that could act in a cumulative fashion to impact the environment and social structure of the region. This work needs to be further refined and confirmed but has been included in an appendix of this document. (Au)
