Our long-term vision is to create a landscape that sustains a healthy diversity of plants and animals, and supports a range of land uses. Our goals are to ensure the final reclaimed landscape has capability equivalent to that existing prior to development, is integrated with the surrounding area, establishes boreal forest upland and lowland communities, yields water suitable for return to the natural environment, and is planned in direct consultation with local, directly affected stakeholders, and Aboriginal communities of interest.
Because we progressively reclaim former mining areas as soon as they are available, rather than delay until the end of mine life, areas available for reclamation vary from year to year depending on the mine plan. Cumulative reclamation continues to increase annually.
Syncrude participates in the Mining Association of Canada’s Towards Sustainable Mining (TSM) initiative, and endorses its Mine Closure Framework. This framework outlines expectations regarding the closure of a mine, including a commitment to work with communities to develop closure plans and identify values that will be incorporated into reclamation objectives, and to research and innovate improved mine closure and monitoring technologies.
Syncrude adheres to the Alberta Environmental Protection and Enhancement Act, which requires us to return the land we use to a productive capability equivalent to that of the pre-disturbance landscape. A mine closure plan is submitted to the government every 10 years, with a mid-term update; a mine reclamation plan is submitted every three years, supplemented with annual progress reports. The most recent mine closure plan was submitted in 2016.
Each Syncrude Joint Venture Participant is liable for its share of financial security regarding the operation’s closure obligation. Information on the Mine Financial Security Program for coal and oil sands companies can be found on the website of the Alberta Energy Regulator.
Syncrude reclaimed 126 hectares in 2016 – 15 per cent more than target – and planted over 400,000 tree and shrub seedlings, which included six species of trees and 13 species of shrubs. Nine native species of grass were also planted or seeded.
More than 3.4 million m3 of surface soil, peat and subsoil material were salvaged in 2016 for use in reclamation, with LFH (leaf litter/fibric/humic, or the top layer recovered from the forest floor) material being placed directly to promote the most productive propagule germination of the native seed bank. Currently, in total, we have stockpiled over 80 million m3 of soil material to support ongoing reclamation activities.
Reclamation of our former East Mine is ongoing. This area is approximately 11.5 km2 in size and bordered by Highway 63 south of our main plant site. Reclamation began in 2000 using composite tails as the landform substrate, or underlying layer.
Construction of the 52-hectare Sandhill Fen research watershed was completed in 2012 and results to date are surpassing expectations. After four growing seasons, the plant community continues to develop and plant health is comparable to that found on a natural site. A 2015 vegetation diversity study showed that almost half of the wetland area is characterized by peat-forming species, and there are 87 plant and 23 moss species. As well, a wide variety of wildlife is inhabiting the watershed, including rodents, bats, frogs and birds.
The interdisciplinary, multi-university research program has made excellent progress towards understanding the water and carbon balance, and there is now evidence the ecosystem is becoming a net carbon accumulating system. Lessons learned are being shared with other members of Canada’s Oil Sands Innovation Alliance (COSIA).
We are now reclaiming 85-hectares immediately adjacent, named the Kingfisher area. It will feature both upland forest and wetland areas, and the reclamation strategy is being informed by lessons learned from the Sandhill Fen. Land-forming work commenced in 2015, and soil placement and vegetation planting is expected to be complete by 2018.
The two watershed systems will be interconnected, with the Sandhill Fen draining water into the Kingfisher’s wetland, which will in turn drain into the Mildred Lake reservoir and eventually into the Athabasca River.
Reclamation of the remainder of the East Mine continues with completion expected by 2022.
Reclamation of our former West Mine began in late 2012 using the method of capping fluid fine tails with water. This area is now capped with water and will be monitored as it evolves towards a fully functional, healthy aquatic ecosystem. Further discussion can be found in the Tailings chapter.
Syncrude invested approximately $69 million on research and development efforts in 2016; of this, over half was directed to environmental projects such as our reclamation research programs and collaborative efforts through COSIA.
We also provide financial grants to Canadian and U.S. universities to assist us in advancing oil sands reclamation science. Among those are:
