SUNCOR ENERGY INC. Base Mine Extension - Project Summary Table February 2020

EXECUTIVE SUMMARY Suncor Energy Inc. (Suncor) is submitting a proposal to develop the Base Mine Extension Project (the Project). All plausible pathways to address global emissions need energy from fossil fuels and Suncor views Canada’s world class, strategic oil sands resource as a key part of the energy future for decades to come. Commensurate with Canada’s ambitions, Suncor is committed to a long-term strategy of reducing absolute emissions. With the innovation we are known for, Suncor can provide the world with trusted low carbon energy. Suncor has invested billions of dollars in infrastructure that produces value added products to meet the energy needs of Albertans and Canadians. This Project is necessary to continue to add value with this infrastructure. The bitumen from this project will be used to supply the existing upgraders at Suncor’s Oil Sands Base Plant operations (Base Plant), when the existing mines are depleted. The Project is adjacent to Base Plant and includes an open pit mining operation and extraction facilities. Production is expected to be nominally 225 thousand barrels per day of replacement bitumen during its estimated 25-year operational life. The Project application will be based on best-available technology. In parallel, Suncor is developing new technologies, such as non-aqueous extraction. These new technologies have the potential to significantly reduce the overall footprint, reclamation timeline, and GHG emissions of mining and will be incorporated as appropriate. In addition, Suncor will concurrently be aggressively pursuing paths to reduce emissions in other areas of its business and in ways that sequester carbon and produce net benefits. Significant socioeconomic benefits and opportunities for Indigenous communities, local communities, the Province of Alberta, and Canada are expected to be generated by the Project. The benefits include:  continued generation of municipal, provincial, and federal tax and royalty revenue;  direct and indirect local and national employment; and  investment in innovation and technology development. Production is anticipated post this decade to support continued operations of existing infrastructure as production transitions from the existing mines to the Project. Suncor is committed to working with regulators, governments, Indigenous communities, and stakeholders to seek approval for this Project, while ensuring we are caring for each other and the earth, with a view to the long-term interests of Canada and its Peoples.

Project Description Suncor Energy Inc. (Suncor) is proposing to develop the Base Mine Extension Project (the Project) to sustain the supply of bitumen to the existing upgraders at Suncor’s Oil Sands Base Plant operation (Base Plant) as the mineable bitumen resource is depleted. The Project includes an open pit mining operation supplying oil sands to new bitumen froth production facilities, from which bitumen froth will be delivered by pipeline to Suncor’s existing Base Plant facilities where further processing occurs including upgrading into various product blends for market. The Project is located adjacent to Base Plant and north of the city of Fort McMurray, Alberta, within the Regional Municipality of Wood Buffalo (Figure 1) in Township 92, Ranges 9-11, West of the 4th Meridian; Township 91, Ranges 9-11, West of the 4th Meridian; and Township 90, Ranges 9-11, West of the 4th Meridian. The Project will include mining and tailings management operations (including an external tailings area), an ore preparation plant, primary extraction plant, surface and groundwater management systems, and reclamation and closure activities. The Project will integrate with existing water, power, heat and fuel utilities and use existing approved secondary extraction and upgrading facilities at the Suncor Base Plant. Infrastructure associated with the Project includes plant site buildings, mining infrastructure, and related linear infrastructure. The Project will include buildings to accommodate direct staff and support services on the Project footprint. Maintenance and emergency services will have facilities on the Project footprint intended to provide the majority of support services required. Some existing support services may remain located at the Suncor Base Plant. Figure 2 provides the preliminary location of these facilities and infrastructure. Some of the pipelines and the power lines required for the Project are part of the existing Suncor Base Plant Alberta Oil Sands Conservation Act approved scheme (Approval No. 8535N). For those not covered under existing approvals, Suncor will make specific applications under the Alberta Pipeline Act and the Alberta Hydro and Electric Energy Act and other relevant legislation prior to project construction.

Land Uses The Project is located within the Lower Athabasca Region of Alberta primarily on Crown lands that are administrated under the Alberta Public Lands Act. The current zoning designation for the Project development area is rural district. The Project development area includes a number of existing land uses, including oil and gas, recreation (including fishing, hunting, using all-terrain vehicles, snowmobiling and canoeing), trapping, traditional uses, and timber harvesting. The Project development area contains both privately owned and Provincial Crown surface rights. Geological exploration drilling has taken place within the Project development area since the 1940s. Environmental Setting The Project is located in the Central Mixedwood natural subregion that is spatially the largest in the province covering 25 percent of Alberta’s land area. The cool boreal climate regime is conducive to the growth of mixed aspen-spruce forests. The Central Mixedwood subregion contains a significant component of wetlands in poorly drained areas. The topography of the project area generally has subdued relief, with nearly level to gently rolling topography. Much of the Project area was impacted by a wildfire that burned through the area in May 2016. Project area/regional valued components identified previously include:  Sport and forage fish species such as Arctic grayling, burbot, goldeye, lake whitefish, mountain whitefish, northern pike, yellow perch, longnose sucker, white sucker, brook stickleback, emerald shiner, fathead minnow, brassy minnow, finescale dace, flathead chub, lake chub, northern redbelly dace, pearl dace, trout-perch, spoonhead sculpin and slimy sculpin;  Terrestrial vegetation including white spruce, jack pine, aspen or mixed stands of aspen, white spruce, balsam poplar and/or white birch;  Forested and non-forested wetlands types; and  Old growth forest areas.  Valued wildlife species include those of ecological significance or with status both nationally and provincially, including moose, black bear, beaver, muskrat, fisher, lynx, woodland caribou, Canadian toad, ducks and geese, old growth forest birds, marsh birds (e.g., yellow rail), mixedwood forest birds, boreal owl and whooping crane. Socioeconomic Characteristics Development of the Wood Buffalo region, and Fort McMurray in particular, has been tied to the development of the oil sands. Prior to commercial development of the oil sands industry, the region’s economy was reliant on its function as a transportation thoroughfare to regions further south, and on traditional resource industries such as hunting, fishing, trapping and forestry. Large-scale development in the region began in the mid-1960s and led to several significant changes over the next five decades. The RMWB is a relatively large and diverse municipality, principally comprised of:  Fort McMurray, a regional service centre with a diverse permanent population of approximately 72 thousand in 2018  smaller rural communities with a combined diverse permanent population estimated at approximately three thousand in 2018  a relatively young population  a shadow population estimated at over 36 thousand, with roughly 90 percent of this population housed in temporary worker dwellings (i.e., camps)  an on-reserve population estimated at just over 1,700 in 2016

Fort McMurray has grown over time from a relatively small, isolated northern town with few amenities into one of Alberta’s larger urban centres. This transition means that the breadth and nature of services and infrastructure in the community have also grown. Today, Fort McMurray offers a range of health, education, social, recreation, and cultural amenities and services that are commensurate with a community of its size. In addition, several of the hamlets within the Regional Municipality of Wood Buffalo also have local community and recreation facilities to support residents in those communities. Potential Issues or Impacts and Potential Adverse Affects Potential environmental issues or impacts and potential adverse effects that may result from the Project development include:  potential impacts to waterbodies, watercourses, water quality and water quantity during operations and at closure, including potential impacts to water access and navigation  potential impacts to quality and quantity of fish and fish habitat during operations and at closure  potential impacts to the wildlife and wildlife habitat during operations and at closure  potential impacts to ecosystems and harvesting areas, such as, loss of traditional use plants and vegetation and reduced quantity of wildlife in harvesting areas  potential impacts to air quality, including odours, noise and dust from operations  potential impacts to health status and Indigenous community health  potential impacts to Indigenous communities, culture and heritage resources, including the inability to practice and pass on Indigenous culture, laws, customs and knowledge  potential impacts on Indigenous communities’ sense of wellbeing, remoteness, solitude, privacy and safety  potential impacts to aesthetics including light pollution Suncor is preparing an Environmental Impact Assessment for the Project Application, which will be a comprehensive assessment of environmental effects in both the local and regional study areas associated with the Project. Suncor will be seeking regulatory approvals under the Environmental Protection and Enhancement Act, Water Act, Public Lands Act and Oil Sands Conservation Act, Navigation and Protection Act and the Fisheries Act. Engagement with the Impact Assessment Agency of Canada will occur to understand Impact Assessment Act requirements. Environmental management and monitoring programs in place at Base Plant will be expanded to accommodate the development and operation of the Project.
