Oil Sands Environmental Management Bibliography

The Cumulative Environmental Management Association (CEMA)partnered with the Oil Sands Research and Information Network (OSRIN) to create the new Oil Sands Environmental Management Bibliography, which includes documents relevant to the environmental management of oil sands development in Alberta. The majority of the documents focus on the mineable oil sands in the Athabasca deposit, though some documents relate to in-situ developments. This bibliography was last updated in November 2014.

Land-use/Land-cover Classifications of the Cold Lake Oil Sands Area Derived from 2013 Landsat Imagery (Image data, Tiff format)

Authors
Year of Publication: 2009

Abstract:
The Cold Lake oil sands area, Township 56 to 69, Range 1 to 11, west of the 4th Meridian, falls within the Lower Athabasca Regional Plan (LARP). As part of Alberta's Land-use Framework, LARP was developed in 2012 to set the stage for robust growth, vibrant communities and a healthy environment within the region. One of its implementation objectives is to balance the economic development of oil sands and impacts on ecosystem and environment. This is to be achieved through enhanced science-based monitoring for improved characterization of the environment and collection of the information necessary to understand cumulative effects. This land classification raster dataset is derived from 2013 Landsat imagery. It contains 13 classes: 0 - unclassified, 1 - exposed land/cut blocks/harvested areas, 2 - water bodies, 3 - transitional bare surfaces, 5 - mixed developed areas, 6 - developed areas, 7- shoal, 8 - shrub land, 9 - grassland, 10 - agriculture areas, 11 - coniferous forest, 12 - broad leaf forest, 13 - mixed forest, and 14- fire scar.

Landscape restoration after oil sands mining: Conceptual design and hydrological modelling for fen reconstruction

Year of Publication: 2010

Abstract:
Extraction of oil sands in the relatively dry Western Boreal Plains near Fort McMurray, Alberta, destroys the natural surface cover including fen peatlands that cover upto 65% of the landscape. Industry and environmental monitoring agencies have questioned the ability to reclaim fen peatlands in the post-mine landscape. This study proposes a conceptual model to replace fen systems with fen peat materials supported by groundwater inflow from a constructed watershed. A numerical model is used to determine the optimum system geometry, including the ratio of upland to fen area, thickness and slope of sand materials, and thickness of peat and of the liner that would result in flows that sustain peat wetness to a critical threshold soil water pressure of −100 cm of water at a peat depth of 10 cm. We also test the sensitivity of the system to variations in the value and spatial configuration of the hydraulic conductivity (K) of locally available materials. The optimal conditions were achieved using an upland area at least twice that of the fen, underlain by a sloping (3%) layer of fine-grained material with hydraulic conductivity (K) of 10−10 m/s, that maintains lateral groundwater flow in a sand layer with K of 10−4 to 10−5 m/s. Using daily climate inputs that included 1998, the driest summer on record, the model suggests that adequate wetness can be sustained in the fen for the growing season, and that the extent of water table recession was similar to undisturbed systems during that period.

Landscapes of perception: Reclaiming the Athabasca oil sands and the Sydney tar ponds

Authors Dance, A. T.
Year of Publication: 2013

Abstract:
This interdisciplinary project offers new insights into the reclamation history of two of the most controversial and contaminated sites in Canadian history: the Sydney tar ponds and coke ovens and the Athabasca oil sands. It argues that Canada’s natural resource-dependent economy, combined with jurisdictional uncertainty, created a hesitant, fragmentary site cleanup regime, one that left room for different ideas about landscapes to shape and even distort reclamation’s goals and processes. In the absence of substantive reclamation standards and legislation, researchers struggled to accommodate the unique challenges of the oil sands during the 1960s and 1970s. Ambitious goals for reclamation faltered, and even the most successful examples of oil sands reclamation differed significantly from the pre-extraction environment; reclamation was not restoration. Planners envisioned transforming northeastern Alberta into a managed wilderness and recreation nirvana, but few of these plans were realised. The Sydney tar ponds experience suggests that truly successful reclamation cannot exist unless past injustices are fully acknowledged, reparations made, and a more complete narrative of contamination and reclamation constructed through open deliberation. Reclamation, after all, does not repair history; nor can it erase the past. Effective oil sands reclamation, then, requires a reconsideration of the site’s past and an acknowledgement of the perpetuated vulnerabilities and injustices wrought by development and reclamation.

Larval fish toxicity of sediments waters groundwaters and snow melt waters from the oil sands area

Year of Publication: 2013

Abstract:
As part of the Joint Canada-Alberta Oil Sands Monitoring Plan, the toxicology of natural and oil sands related environmental samples was studied. One of the goals of the toxicity tests is to examine pathways and sources of contaminants that may be causing effects in wild fish and invertebrates. Samples were collected from sites where wild fish health assessments and invertebrate communities were assessed. In this way, linkages could be made between wild invertebrates and fish, in comparison to controlled studies of lab fish exposed to certain components of the environment (sediment, water, groundwater, and snowmelt). Embryo-larval fathead minnows were used to assess the chronic toxicity of the following environmental samples: river sediments, river waters, groundwaters, snow melt waters, spring freshet waters, and suspended sediments collected in the vicinity of the Canadian oil sands. Samples were collected in 2009- 2013 from rivers near oil sands processing facilities along the Athabasca River and tributaries in areas of oil sands development, and compared to samples collected far from sites of oil sands mining and processing. Fertilized fathead minnow eggs were exposed for 21 days (through hatch to 7-15 days post-hatch) to samples in dose- response gradients. Most environmental samples caused no effects in larval fish in 21 day assays. Samples that caused effects in larval fathead minnows were several snow melt samples, several groundwaters, sediments from the Steepbank and Ells Rivers, and waters from the Muskeg River. Some of the toxic samples were from sites close to industry (Steepbank River sediments, snow samples close to stacks, Muskeg River waters). Other samples (groundwaters, Ells River waters) showed toxicity far from oil sands activities, with effects in lab fish seen at “background’ sites where natural oil sands weathering or water movement thru bitumen occurs. Samples were analyzed for naphthenic acids, PAHs, C1-C4 alkylates PAHs, and metals. Sites where sediments and waters were toxic in lab fish bioassays are being assessed to determine whether wild young-of-year fish are abundant and growing normally in these areas of potentially toxic sediments or waters. The results of this work will help guide future studies and locations to sample wild fish and invertebrates to fully assess environmental health in the oil sands area.

Leaching of vanadium and other metals from Athabasca oil sands coke and coke ash

Year of Publication: 1979

Abstract:
Flexicoker coke derived from Athabasca Oil Sands bitumen contains a number of heavy metals, including vanadium, nickel, iron and titanium, which are susceptible to extraction by hydrometallurgical procedures. The leaching behaviour has been studied as a function of pH, temperature and the presence of salts and redox agents. Greater than 50% extraction of the vanadium, iron and nickel can be achieved by acid leaches, but only about 20% of the titanium can be extracted. Weakly acidic leaches extract about 30% of the nickel content but no significant amounts of the other metals. If cokes derived from Athabasca Oil Sands bitumen by the flexicoking process or the conventional delayed-coker coking process are combusted at temperatures below 500 °C, the vanadium and nickel values in the residual ash are readily susceptible to acid leaching.

Legacy of a half century of Athabasca oil sands development recorded by lake ecosystems

Year of Publication: 2013

Abstract:
The absence of well-executed environmental monitoring in the Athabasca oil sands (Alberta, Canada) has necessitated the use of indirect approaches to determine background conditions of fresh- water ecosystems before development of one of the Earth’s largest energy deposits. Here, we use highly resolved lake sediment records to provide ecological context to ∼50 y of oil sands development and other environmental changes affecting lake ecosystems in the re- gion. We show that polycyclic aromatic hydrocarbons (PAHs) within lake sediments, particularly C1-C4–alkylated PAHs, increased signif- icantly after development of the bitumen resource began, followed by significant increases in dibenzothiophenes. Total PAH fluxes in the modern sediments of our six study lakes, including one site ∼90 km northwest of the major development area, are now ∼2.5–23 times greater than ∼1960 levels. PAH ratios indicate temporal shifts from primarily wood combustion to petrogenic sources that coincide with greater oil sands development. Canadian interim sediment qual- ity guidelines for PAHs have been exceeded since the mid-1980s at the most impacted site. A paleoecological assessment of Daphnia shows that this sentinel zooplankter has not yet been negatively impacted by decades of high atmospheric PAH deposition. Rather, coincident with increases in PAHs, climate-induced shifts in aquatic primary production related to warmer and drier conditions are the primary environmental drivers producing marked daphniid shifts af- ter ∼1960 to 1970. Because of the striking increase in PAHs, elevated primary production, and zooplankton changes, these oil sands lake ecosystems have entered new ecological states completely distinct from those of previous centuries.

Legal and policy responses to environmental offences in relation to the Alberta oil sands

Authors Nwapi, C.
Year of Publication: 2012

Abstract:
Media reports about the environmental effects of oil sands development have engendered public scrutiny of environmental enforcement in the Alberta oil sands. In an article captioned “The Canadian Oil Boom: Scraping Bottom”,1 the National Geographic featured a horrific but vivid image of the environmental risks associated with the oil sands. Environmentalists say there is growing scientific evidence that oil sands extraction produces more carbon dioxide than traditional oil extractions produce.2 Last February, a group of Nobel laureates urged European leaders to support European Union’s proposal to categorize fuel from oil sands as “highly polluting”.3 In their words, “[t]ar sand development is the fastest growing source of greenhouse gas emissions in Canada, and threatens the health of the planet.”4 In a letter to Canada’s Prime Minister Stephen Harper, the laureates demanded that as the Prime Minister has called climate change one of mankind’s biggest problems, he should translate his words into deeds by halting further expansion of the oil sands.5 One observer has noted that even “oil-obsessed” United States deferred its plans for the Keystone XL pipeline that would have increased the amount of oil sands produced by Canada for onward transportation to the US.6 Although the EU’s vote ended in a deadlock, due in large part to intense lobbying by Canada with threats of a trade war with the EU,7 objections to the oil sands remain nevertheless. The purpose of this article is to review the environmental enforcement culture in Alberta with a view to ascertaining what mechanisms are in place in Alberta for responding to the commission of environmental offences, especially in the context of the oil sands, and the extent to which those mechanisms are being used.

Levels of polycyclic aromatic hydrocarbons and dibenzothiophenes in wetland sediments and aquatic insects in the oil sands area of northeastern Alberta, Canada

Year of Publication: 2008

Abstract:
An immense volume of tailings and tailings water is accumulating in tailings ponds located on mine leases in the oil sands area of Alberta, Canada. Oil sands mining companies have proposed to use tailings- and tailings water-amended lakes and wetlands as part of their mine remediation plans. Polycyclic aromatic hydrocarbons (PAHs) are substances of concern in oil sands tailings and tailings water. In this study, we determined concentrations of PAHs in sediments, insect larvae and adult insects collected in or adjacent to three groups of wetlands: experimental wetlands to which tailings or tailings water had been purposely added, oil sands wetlands that were located on the mine leases but which had not been experimentally manipulated and reference wetlands located near the mine leases. Alkylated PAHs dominated the PAH profile in all types of samples in the three categories of wetlands. Median and maximum PAH concentrations, especially alkylated PAH concentrations, tended to be higher in sediments and insect larvae in experimental wetlands than in the other types of wetlands. Such was not the case for adult insects, which contained higher than expected levels of PAHs in the three types of ponds. Overlap in PAH concentrations in larvae among pond types suggests that any increase in PAH levels resulting from the addition of tailings and tailings water to wetlands would be modest. Biota-sediment accumulation factors were higher for alkylated PAHs than for their parent counterparts and were lower in experimental wetlands than in oil sands and reference wetlands. Research is needed to examine factors that affect the bioavailability of PAHs in oil sands tailings- or tailings water-amended wetlands.

Lidar observation of plume dispersion in northern Alberta

Year of Publication: 1979

Abstract:
The particulate plume from the power plant of Great Canadian Oil Sands, Ltd. was observed using a mobile laser radar (LIDAR). Thirteen Eulerian average cross sections were obtained from which the horizontal and vertical dispersion coefficients, plume rise and plume bearing were derived. The methodology for extracting these parameters from LIDAR scans is presented. Comparison with Gaussian plume formulae show valley effects and wind shear under stable regimes to be important for this region.

Life after NRBS: A proposal for interjurisdictional management of the Peace Athabasca and Slave River basins

Authors Stager, J.
Year of Publication: 1995

Abstract:
The Board of the Northern River Basins Study posed a series of questions as a basis for meeting its mandate. Question16,whichaddressedthefuture,asked"Whatformofinterjurisdictionalbodycan be established, ensuring stakeholders participation fo r the ongoing protection and use o f the river basins?" This paper summarizes the working background for an answer. It sets the stage by proposing seven principles to crystallize the work of the Study, and in a similar number of goals, suggests what kind of river system is wanted. It then reviews models of other organizations structures used in similar situations. The uniqueness ofthe NRBS region makes it awkward to import something from outside. To make the case, special features about science and monitoring in the Basins, the overlap of special legislative conditions, and the roles of stakeholder, the public at large and First Nations are all examined to provide the background against which to decide. After considering preliminary results o f a stakeholder and household survey which firmly supported the establishment o f some post-NRBS infrastructure, the paper concludes that Question 16 is indeed legitimate and needs an answer. Progress towards an answer is materially helped by a study by Steven Kennett and Owen Saunders (see references). Their pattern of thinking is applied to the NRBS situation and a series of conclusions offered as a basis for advancing an administrative strategy to recommend to the Board. In approaching these recommendations, a choice is exercised to propose a fairly firm and tightly constructed option, which might seem rigid but is calculated to be responsive to the very broad range of scientific and semi-political issues that are judged unique to this region. Furthermore, it seeks to be sensitive to constraints faced by present governments both in thinking and resources. A two-tiered model is advanced, described through twenty-six separate recommendations. Based upon an Agreement between relevant governments, the first tier is a Board, with fairly broad representation that is seen as concerned mainly with interjurisdictional, whole river basin management. With due consideration, supported by research and public advice, this offers direction to the governments that created the Board. Separate from and independent of the Board, but within the Agreement, is a Committee, again, broadly representative of governments, First Nations, stakeholders and public, to oversee the stewardship of the management functions. Both units are seen to be economical in size and funded by partners in the Agreement. It is suggested that this be tried for five years, and reviewed thereafter. The proposal is designed so that it could fit within the Transboundary Management Agreement for Mackenzie River Basin which has been negotiated, but not yet signed. Appended to the paper, as an example, is a Draft Agreement of the type which the governments of Alberta, Northwest Territories, and Canada might conclude to meet the needs of the recommended structures.

Life cycle energy and greenhouse gas emissions from transportation of Canadian oil sands to future markets

Authors Tarnoczi, T.
Year of Publication: 2013

Abstract:
Oil sands transportation diversification is important for preventing discounted crude pricing. Current life cycle assessment (LCA) models that assess greenhouse gas (GHG) emissions from crude oil transportation are linearly-scale and fail to account for project specific details. This research sets out to develop a detailed LCA model to compare the energy inputs and GHG emissions of pipeline and rail transportation for oil sands products. The model is applied to several proposed oils sands transportation routes that may serve as future markets. Comparison between transportation projects suggest that energy inputs and GHG emissions show a high degree of variation. For both rail and pipeline transportation, the distance over which the product is transported has a large impact on total emissions. The regional electricity grid and pump efficiency have the largest impact on pipeline emissions, while train engine efficiency and bitumen blending ratios have the largest impact on rail transportation emissions. LCA-based GHG regulations should refine models to account for the range of product pathways and focus efforts on cost-effective emission reductions. As the climate-change impacts of new oil sands transportation projects are considered, GHG emission boundaries should be defined according to operation control.

Life cycle greenhouse gas emissions of current oil sands technologies: GHOST model development and illustrative application

Year of Publication: 2011

Abstract:
A life cycle-based model, GHOST (GreenHouse gas emissions of current Oil Sands Technologies), which quantifies emissions associated with production of diluted bitumen and synthetic crude oil (SCO) is developed. GHOST has the potential to analyze a large set of process configurations, is based on confidential oil sands project operating data, and reports ranges of resulting emissions, improvements over prior studies, which primarily included a limited set of indirect activities, utilized theoretical design data, and reported point estimates. GHOST is demonstrated through application to a major oil sands process, steam-assisted gravity drainage (SAGD). The variability in potential performance of SAGD technologies results in wide ranges of "well-to-refinery entrance gate" emissions (comprising direct and indirect emissions): 18-41 g CO(2)eq/MJ SCO, 9-18 g CO(2)eq/MJ dilbit, and 13-24 g CO(2)eq/MJ synbit. The primary contributor to SAGD's emissions is the combustion of natural gas to produce process steam, making a project's steam-to-oil ratio the most critical parameter in determining GHG performance. The demonstration (a) illustrates that a broad range of technology options, operating conditions, and resulting emissions exist among current oil sands operations, even when considering a single extraction technology, and (b) provides guidance about the feasibility of lowering SAGD project emissions.

Life cycle greenhouse gas emissions of current oil sands technologies: Surface mining and in situ applications

Authors Sleep, S.
Year of Publication: 2012

Abstract:
Life cycle greenhouse gas (GHG) emissions associated with two major recovery and extraction processes currently utilized in Alberta's oil sands, surface mining and in situ, are quantified. Process modules are developed and integrated into a life cycle model-GHOST (GreenHouse gas emissions of current Oil Sands Technologies) developed in prior work. Recovery and extraction of bitumen through surface mining and in situ processes result in 3-9 and 9-16 g CO(2)eq/MJ bitumen, respectively; upgrading emissions are an additional 6-17 g CO(2)eq/MJ synthetic crude oil (SCO) (all results are on a HHV basis). Although a high degree of variability exists in well-to-wheel emissions due to differences in technologies employed, operating conditions, and product characteristics, the surface mining dilbit and the in situ SCO pathways have the lowest and highest emissions, 88 and 120 g CO(2)eq/MJ reformulated gasoline. Through the use of improved data obtained from operating oil sands projects, we present ranges of emissions that overlap with emissions in literature for conventional crude oil. An increased focus is recommended in policy discussions on understanding interproject variability of emissions of both oil sands and conventional crudes, as this has not been adequately represented in previous studies

Life history variation of inconnu (Stenodus leucichthys) and burbot (Lota lota), lower Slave River, June to December, 1994

Year of Publication: 1996

Abstract:
To determine the life cycle and demographic characteristics of the inconnu, Stenodus leucichthys, and burbot, Lota lota in the Slave River, Northwest Territories, we sampled between June and December, 1994. Inconnu are migratory utilizing the Slave River for spawning. They were most abundant in the river in late September and October. Based upon thegonadosomaticindex, inconnuprobablyspawninmid-tolate-OctoberintheSlaveRiver. Burbot appear to be highly sedentary in the open water season because few were caught until December under ice cover. Inconnu had faster growth rates and earlier age-at-maturity ( ages 5-7 for males and 7-9 for females) than more northerly inconnu populations. In contrast, burbot matured later (age 5) and grew more slowly than other populations. Inconnu mean fecundity-at-age was between 108,086 to 124,493 eggs per female. Based on the demographics of the two species in the Slave River, inconnu would be more vulnerable to environmental change.

Limitation of fluorescence spectrophotometry in the measurement of naphthenic acids in oil sands process water

Year of Publication: 2013

Abstract:
Fluorescence spectrophotometry has been proposed as a quick screening technique for the measurement of naphthenic acids (NAs). To evaluate the feasibility of this application, the fluorescence emission spectra of NAs extracted from three oil sands process water sources were compared with that of commercial NAs. The NAs resulting from the bitumen extraction process cannot be differentiated because of the similarity of the fluorescence spectra. Separation of the fluorescent species in NAs using high performance liquid chromatography with fluorescence detector proved unsuccessful. The acidic fraction of NAs is fluorescent but the basic fraction of NAs is not fluorescent, implying that aromatic acids in NAs give rise to the fluorescent signals. The concentrations of NAs in oil sands process water were measured by Fourier transform infrared spectroscopy (FTIR), fluorescence spectrophotometry and ultra high performance liquid chromatography-time of flight/mass spectrometry (UPLC-TOF/MS). Commercial Merichem and Kodak NAs are the best standards to use when measuring NAs concentration with FTIR and fluorescence spectrophotometry. In addition, the NAs concentrations measured by fluorescence spectrophotometry are about 30 times higher than those measured by FTIR and UPLC-TOF/MS. The findings in this study underscore the limitation of fluorescence spectrophotometry in the measurement of NAs.

Linkage of annual oil sands mine plan to composite tailings plan

Authors Kalantari, S.
Year of Publication: 2011

Abstract:
One of the major issues in the current oil sands waste management techniques is a lack of a direct linkage between the long-term mine plans and the quantity of the tailings produced downstream. This research is focused on developing a linkage between oil sands long-term mine plans and the final composite tailings (CT) produced to assist the oil sands production process to be in compliance with the regulations set by Directive 074. A series of mass-balance relations between the ore tonnage and the final CT tonnage were developed. This was followed by the development of a code to employ the mass-balance relations in reporting the CT production schedule using the long-term mine plan. To capture the uncertainties associated with the CT production process, a stochastic simulation model was developed. Finally, sensitivity analysis was carried out to capture the sensitivity of the CT tonnages produced to the fluctuations of the input variables.

Liquid chromatographic resolution of various isomers in oil sands process water by extended column length and elevated temperature

Year of Publication: 2013

Abstract:
Qualitative and quantitative analyses of surface mining OSPW from the Canadian Athabasca region poses a great technical challenge due to the wide variety of isomers (i.e. >200,000 individual compounds are estimated) that have proven difficult to separate by current LC-based methods. In this study, we established a high separation efficiency method by coupling several columns at high temperature, and by using the ultra-high resolution Orbitrap detector to better understand the structure of isomers that are resolved. Results showed that the theoretical plates on each column were approximately 26000 at 30°C at a flow rate of 0.5ml/min, and that plate counts remained constant at different temperatures (30°C and 60°C). At 60°C, four XSELECT CSH C18 XP columns (130Å, 2.5μm, 3mm×150mm) could be coupled to generate 105,000 effective plates at a back pressure of 718 bar. The method was tested with OSPW sample using Thermo ScientificTM Orbitrap Elite, the Trennzahl (TZ) for adjacent peaks increased from 2.4 to 5.5with the retention time extending from 9 min to 39 min, providing improved resolution of isomers for various chemical groups in OSPW.
