Investigating the potential of thecamoebians (testate amoebae) as bio-indicators of impact of oil sands mining operations on freshwater environments in Northeastern Alberta, Canada

Thecamoebian (testate amoeba) species diversity and assemblages in reclamation wetlands and lakes in northeastern Alberta respond to chemical and physical parameters associated with oil sands extraction. Ecosystems more impacted by OSPM (oil sands process-affected material) contain sparse, low-diversity populations dominated by centropyxid taxa and Arcella vulgaris. More abundant and diverse thecamoebian populations rich in difflugiid species characterize environments with lower OSPM concentrations. These shelled protists respond quickly to environmental change, allowing year-to-year variations in OSPM impact to be recorded. Their fossil record thus provides corporations with interests in the Athabasca Oil Sands with a potential means of measuring the progression of highlyimpacted aquatic environments to more natural wetlands. Development of this metric required investigation of controls on their fossil assemblage (e.g. seasonal variability, fossilization potential) and their biogeographic distribution, not only in the constructed lakes and wetlands on the oil sands leases, but also in natural environments across Alberta.

EVALUATING THE OIL SANDS RECLAMATION PROCESS: ASSESSING POLICY CAPACITY AND STAKEHOLDER ACCESS FOR GOVERNMENT AND NON-GOVERNMENTAL ORGANIZATIONS OPERATING IN ALBERTA’S OIL SANDS

By employing interpretive policy analysis this thesis aims to assess, measure, and explain policy capacity for government and non-government organizations involved in reclaiming Alberta's oil sands. Using this type of analysis to assess policy capacity is a novel approach for understanding reclamation policy; and therefore, this research will provide a unique contribution to the literature surrounding reclamation policy. The oil sands region in northeast Alberta, Canada is an area of interest for a few reasons; primarily because of the vast reserves of bitumen and the environmental cost associated with developing this resource. An increase in global oil demand has established incentive for industry to seek out and develop new reserves. Alberta's oil sands are one of the largest remaining reserves in the world, and there is significant interest in increasing production in this region. Furthermore, tensions in several oil exporting nations in the Middle East remain unresolved, and this has garnered additional support for a supply side solution to North American oil demands. This solution relies upon the development of reserves in both the United States and Canada. These compounding factors have contributed to the increased development in the oil sands of northeastern Alberta. Essentially, a rapid expansion of oil sands operations is ongoing, and is the source of significant disturbance across the region. This disturbance, and the promises of reclamation, is a source of contentious debates amongst stakeholders and continues to be highly visible in the media. If oil sands operations are to retain their social license to operate, it is critical that reclamation efforts be effective. One concern non-governmental organizations (NGOs) expressed criticizes the current monitoring and enforcement of regulatory programs in the oil sands. Alberta's NGOs have suggested the data made available to them originates from industrial sources, and is generally unchecked by government. In an effort to discern the overall status of reclamation in the oil sands this study explores several factors essential to policy capacity: work environment, training, employee attitudes, perceived capacity, policy tools, evidence based work, and networking. Data was collected through key informant interviews with senior policy professionals in government and non-government agencies in Alberta. The following are agencies of interest in this research: Canadian Association of Petroleum Producers (CAPP); Alberta Environment and Sustainable Resource Development (AESRD); Alberta Energy Regulator (AER); Cumulative Environmental Management Association (CEMA); Alberta Environment Monitoring, Evaluation, and Reporting Agency (AEMERA); Wood Buffalo Environmental Association (WBEA). The aim of this research is to explain how and why reclamation policy is conducted in Alberta's oil sands. This will illuminate government capacity, NGO capacity, and the interaction of these two agency typologies. In addition to answering research questions, another goal of this project is to show interpretive analysis of policy capacity can be used to measure and predict policy effectiveness. The oil sands of Alberta will be the focus of this project, however, future projects could focus on any government policy scenario utilizing evidence-based approaches.

Integrating vitrinite reflectance, rock-eval pyrolysis, flourescence microscopy and palynology of the Athabasca oil sands, Kearl Lake area, northeastern Alberta

Three cores from the Kearl Lake Oil Sands area within the Athabasca deposit of northeastern Alberta have been analyzed to understand the thermal history of the McMurray and Clearwater formations of the Lower Cretaceous Mannville Group. The approach involves the integration of vitrinite reflectance (VR), Rock-Eval pyrolysis, fluorescence microscopy, and palynology. Mean VR varies between 0.21 and 0.43% Ro and indicates thermally immature levels equivalent to the rank of lignite to sub-bituminous coal. Although differing lithologies have influenced VR to some extent (i.e., coals and bitumen-rich zones), groundwater influence and oxidation seem not to have measurably altered YR. Rock-Eval analysis points to Type III/IV kerogen, and samples rich in amorphous organic matter (ADM) show little to no fluorescence characteristics, implying a terrestrial source of origin. Palynology reveals the presence of some delicate macerals but lack of fluorescence and abundant ADM suggests some degradation and partial oxidation of the samples.

Development of An Enhanced Oil Sands Fluid Tailings Generation Model

Bitumen extraction from surface-mined oil sands results in the production of large volumes of Fluid Fine Tailings (FFT). Through Directive 085, the Province of Alberta has signaled that oil sands operators must improve and accelerate the methods by which they deal with FFT production, storage and treatment. This thesis aims to develop an enhanced method to forecast FFT production based on specific ore characteristics. A mass relationship and mathematical model to modify the Forecasting Tailings Model (FTM) by using fines and clay boundaries, as the two main indicators in FFT accumulation, has been developed. The modified FTM has been applied on representative block model data from an operating oil sands mining venture. An attempt has been made to identify order-of-magnitude associated tailings treatment costs, and to improve financial performance by not processing materials that have ultimate ore processing and tailings storage and treatment costs in excess of the value of bitumen they produce. The results on the real case study show that there is a 53% reduction in total tailings accumulations over the mine life by selectively processing only lower tailings generating materials through eliminating 15% of total mined ore materials with higher potential of fluid fines inventory. This significant result will assess the impact of Directive 082 on mining project economic and environmental performance towards the sustainable development of mining projects.

MATURE FINE TAILINGS (MFTs): A STUDY OF COMPRESSIVE STRENGTH AND RHEOLOGICAL PROPERTIES OF ATHABASCA OIL SANDS PETROLEUM MINING WASTE APPLIED IN CONCRETE MIXTURES

This study investigates the compressive properties of concrete incorporating Mature Fine Tailings (MFTs) waste stream from a tar sands mining operation. The objectives of this study are to investigate material properties of the MFT material itself, as well as establish general feasibility of the utilization of MFT material in concrete mixtures through empirical data and visual observations. Investigations undertaken in this study consist of moisture content, materials finer than No. 200 sieve, Atterburg Limits as well as visual observations performed on MFT material as obtained. Control concrete mixtures as well as MFT replacement mixture designs (% by wt. of water) were guided by properties of the MFT material that were experimentally established. The experimental design consists of compression testing of 4”-diameter concrete cylinders of a control mixture, 30% MFT, 50% MFT and 70% MFT replacement mixtures with air-entrainer additive, as well as a control mixture and 30% MFT replacement mixture with no air-entrainer. A total of 6 mixtures (2 control mixtures, 4 replacement mixtures) moist-cured in lime water after 24 hours initial curing were tested for ultimate compressive strength at 7 days and 28 days in accordance to ASTM C39. The test results of fresh concrete material show that the addition of air-entrainer to the control mixture increases slump from 4” to 5.5”. However, the use of MFT material in concrete mixtures significantly decreases slump as compared to controls. All MFT replacement mixtures (30%, 50%, and 70%) with air-entrainer present slumps of 1”. 30% MFT with no air-entrainer presents a slump of 1.5”. It was found that 7-day ultimate compressive stress was not a good predictor of 28-day ultimate compressive stress. 28-day results indicate that the use of MFT material in concrete with air-entrainer decreases ultimate compressive stress for 30%, 50% and 70% MFT replacement amounts by 14.2%, 17.3% and 25.1% respectively.

Développement de nouveaux polymères amphiphiles comme floculants versatiles pour le traitement de l’eau issue de l’industrie pétrolière

Les polymères hydrosolubles sont utilisés dans diverses industries pour permettre la floculation, soit une séparation solide-liquide de particules présentes en suspension colloïdale. Afin de réduire les impacts environnementaux de l’exploitation des sables bitumineux en Alberta, l’industrie est à la recherche de nouveaux moyens et procédés pour traiter les résidus miniers permettant de séparer les matières solides et de récupérer l’eau. L’objectif des travaux présentés est d’améliorer la floculation, la densification et la déshydratation de ces résidus miniers aqueux par de nouveaux polymères synthétiques. Des homopolymères d’acrylamide de différentes masses molaires ont été synthétisés pour étudier l’influence de la masse molaire sur l’efficacité de floculation. Le taux initial de sédimentation (TIS) est le paramètre qui fut utilisé afin de comparer l’efficacité de floculation des différents polymères. Il a été possible de confirmer l’importance de la masse molaire sur l’efficacité de floculation et de déterminer une masse molaire minimale d’environ 6 MDa pour des polyacrylamides, afin d’obtenir l’efficacité de floculation maximale de suspensions colloïdales principalement composées de kaolin. Afin d’étudier l’effet des charges sur l’efficacité de floculation, des polymères anioniques et cationiques ont été synthétisés. Une série de copolymères d’acrylamide et d’acide acrylique ont été synthétisés comme polymères anioniques et deux séries de copolymères ont été synthétisés comme polymères cationiques, soit des copolymères d’acrylamide et de chlorure de diallyldiméthylammonium et des copolymères de 4-vinyl pyridine et de 1-méthyl-4-vinyl pyridinium. Il a été démontré que les charges anioniques des polymères avaient peu d’influence sur l’efficacité de floculation et que leur comportement en présence de sels était différent de ce que prévoyait la littérature. Il a aussi été démontré que les charges cationiques des polymères n’améliorent pas l’efficacité de floculation. Par la suite, des séries de copolymères amphiphiles, avec des monomères d’acrylamide, de N-alkylacrylamides et d’acrylonitrile, ont été synthétisés, pour étudier l’effet du caractère amphiphile sur la déshydratation des résidus miniers. Le pourcentage de déshydratation nette est le paramètre qui fut utilisé afin de comparer l’efficacité de déshydratation des différents polymères. Il a été possible de développer des copolymères amphiphiles qui améliorent l’efficacité de déshydratation par rapport à des homopolymères d’acrylamide. Il ne fut pas possible de déterminer une tendance entre la balance hydrophile/hydrophobe des copolymères amphiphiles et l’efficacité de déshydratation.

When petro-capitalism comes knocking: community interpretations and responses to the Gros Morne fracking controversy

With the depletion of conventional oil and gas sources, the world is turning to what Urry terms “tough oil,” such as oil from the Alberta oil sands and Arctic. Fracking is a prominent example of this. Situated within an environmental justice framework, I analyze community interpretations and responses to proposed fracking development near Gros Morne National Park, Newfoundland, Canada. Based on data generated from interviews, field observations and content analysis of texts, my findings suggest that how residents view rural place is highly significant in influencing supportive or oppositional positions on fracking. Proponents picture place as a resource extraction landscape, whereas opponents understand place as a restorative landscape for leisure/tourism activities. Through debates about fracking, place is contested and re-imagined. In many ways, fracking is a struggle over who has the power to define the meanings and characteristics of rural community in an era of tough oil and significant rural change.
