MINE GEOTECHNICAL AND GEOLOGY 9 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 1 INTRODUCTION
This report contains information required for annual fluid tailings management reporting for Jackpine Mine (JPM) and is prepared by Canadian Natural Upgrading Limited (Canadian Natural) in accordance with the October 12, 2017, edition of Directive 085: Fluid Tailings Management for Oil Sands Mining (D085), provided under the Oil Sands Conservation Act. As required in the directive, this Fluid Tailings Management Report (FTMR) is prepared annually for the Alberta Energy Regulator (AER). Data collected between nominally July 1, 2018 and June 30, 2019 (corresponding to the mid-year Annual Tailings Investigation) are presented and related to metrics and targets as approved under the JPM Fluid Tailings Management Plan (FTMP) (for AER Commercial Scheme Approval No. 9756H, as amended). This includes operational data, results of the 2019 Annual Tailings Investigation (ATI), and supplementary data related to specific tailings technologies in operation and development at JPM.
It should be noted that this report has changed from a December 31 (year-end) to a June 30 (year-end) as per the requirement changes outlined in the letter received by Canadian Natural from the AER on January 27, 2020.
MINE GEOTECHNICAL AND GEOLOGY 10 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 2 TAILINGS MANAGEMENT ACTIVITIES
Tailings are currently stored in the External Tailings Facility (ETF) and Fluid Cell 1 (FC 1) at JPM. The ETF consists of three storage areas called Dedicated Disposal Area 1 (DDA 1), Sand Cell 1 (SC 1), and Sand Cell 2 (SC 2), as illustrated in Figure 1. This section provides information relevant to tailings management activities that occurred in these areas during the reporting period.
2.1 AER Required Fluid Tailings Accounting Fluid Tailings (FT) volumes at JPM, as they relate to the approved requirements laid out in Commercial Scheme Approval No. 9756H (as amended), are included in Appendix B, both in tabular and graphical forms.
2.2 Management Level Jackpine Mine is currently operating under “Management Level 1”, based on the measured FT volumes presented in Appendix B, as per Table 1 of D085. As such, the following managerial actions are being executed:
An annual review of the interpretation of the ATI is performed to ensure effective reporting and provide verification that targets are achieved. Trends in historic data are annually reviewed and used to calculate and refine parameters used for tailings modelling and planning purposes. Continued investment in tailings treatment technology development is in place. All standard regulatory requirements continue to be fulfilled.
2.3 Dedicated Disposal Area 1 Dedicated Disposal Area 1 is the primary destination for treated tailings at JPM. Thickened Tailings (TT) and centrifuge product are both discharged in the northwest corner of DDA 1. The centrifuge product is discharged from two separate sets of lines that deliver centrifuge product and centrate (water removed in centrifuges). Dedicated Disposal Area 1 also receives Coarse Sand Tailings (CST) that is used for dyke construction and the formation of CST beaches. The Beach Above Water (BAW) portions of these beaches are consistent in composition and strength to conventional CST beaches; however, the Beach Below Water (BBW) portions have been noted to contain significant amounts of fines that have been re- entrained into the beach from the pond fluid. Coarse Sand Tailings were primarily beached from the western edge of the pond and from the northwest corner during the reporting period. Dedicated Disposal Area 1 receives water from the seepage pond and FC 1 depending on water management requirements.
The FT and water that are generated from these depositional activities were previously transferred from the southeast corner of DDA 1 into SC 1 via a pumping system. Towards the end of 2018, the pond level rose sufficiently to produce flow through a channel excavated between DDA 1 and SC 1. Fluid can now flow to SC 1 through this open channel. The FT may contain fines from CST beaching, runoff from TT deposition, and some centrifuge product. During 2020, the cross-dyke separating DDA 1 and SC 1 will be overtopped. The two ponds will be merged for reporting purposes at that time; however, for planning purposes, they are already considered one pond as reclaim water produced in DDA 1 reports directly to SC 1. The locations of these fluid transfer systems are shown in Figure 2.
MINE GEOTECHNICAL AND GEOLOGY 11 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020
2.4 Sand Cell 1 Coarse Sand Tailings continues to be discharged into SC 1 to form conventional CST beaches. Both FT and water have been flowing into SC 1 from DDA 1 through a channel located in the southwest corner of the pond. Some seepage water is also pumped back up into SC 1 from the seepage pond. Water from SC 2 is also periodically transferred into SC 1 to maintain required pond levels in SC 2.
Fluid Tailings from SC 1 are constantly dredged to provide feed for the centrifuge operation. Reclaim water is also taken from SC 1, almost 70% of which is transferred to Muskeg River Mine (MRM) to be recycled back into the Froth Units that treat JPM froth, while the remainder is used by the JPM extraction plant. The locations of these fluid transfer systems are shown in Figure 2.
2.5 Sand Cell 2 Coarse Sand Tailings are discharged into SC 2 to develop cell constructed beaches and form conventional CST beaches along the northern, eastern, and southern perimeters of the cell. A dredge installed in the northwest corner of the SC 2 pond transfers water and FT to SC 1. Fluid transfer to SC 1 is conducted regularly to maintain pond elevations in SC 2. The locations of these fluid transfer systems are also shown in Figure 2.
2.6 Fluid Cell 1 Fluid Cell 1 was used for water and FT storage during the reporting period. Fluid Tailings was transferred from SC 1 in the latter half of 2016; however there were no transfers during the reporting period. The FC 1 reclaim system has been in operation since the last quarter of 2017 and continues to transfer water to DDA 1. The location of this fluid transfer system is shown in Figure 3.
MINE GEOTECHNICAL AND GEOLOGY 12 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 3 ANNUAL TAILINGS INVESTIGATION PROGRAM
The 2019 ATI program was conducted at JPM from July 9, 2019 to September 5, 2019. The investigation consisted of sampling locations, Cone Penetration Testing (CPT) locations, mudline measurements, instrument installations and drop soundings across the DDA 1, SC 1, SC 2, and FC 1 tailings ponds. Table 1 summarises the testing activities performed in the 2019 ATI. Figure 4 provides plan views of the testing locations for each JPM tailings pond.
Testing Activity Number Performed Sampling Location 73 CPT 55 Drop Sounding(a) 187 (a)ConeTec CT09
Table 1: Activities Performed for ATI
3.1 Laboratory Testing A laboratory testing program was conducted on samples collected during the ATI to characterize the JPM tailings deposits. The laboratory testing included:
Moisture Content (MC); Dean Stark (DS); 75 μm and 44 μm mineral solids fraction using wet sieve (WS); Methylene Blue Index (MBI); and Total Suspended Solids (TSS) on Clear Water Zone (CWZ) samples. A total of 1,296 samples from the annual tailings investigation were tested. All testing was conducted in accordance with Canadian Natural’s standard laboratory testing procedures and American Society for Testing and Materials (ASTM) standards. Further information on Canadian Natural’s tailings investigation standard working procedures is detailed in Muskeg River Mine and Jackpine Mine Tailings Measurement Plan (Canadian Natural, 2018).
As indicated in the SIR response submitted to the AER on December 6, 2019, Canadian Natural does not perform routine analysis to characterize the tailings clay fraction beyond MBI, which is only performed on FT samples to inform treatment efficacy.
3.2 Survey As-built and LIDAR surveys were used with pond measurements conducted during the time of the ATI to model the volumes of tailings deposits. Original ground surveys were used to supplement the pond survey data as required. Further details of this process and the interpretation of the survey data for the reporting period are further outlined in the following sections.
3.3 Classification of Treated Tailings, Fluid Tailings, and Clear Water Zone Canadian Natural generally classifies oil sands tailings into three main types: solid tailings, FT, and CWZ. Definitions of the tailings types, the different tailings zones, and the in situ measurement techniques used to delineate them are described in the glossary of terms (Section 15).
MINE GEOTECHNICAL AND GEOLOGY 13 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020
3.4 Methodology to Address Uncertainty in Data There are sources of uncertainty throughout the process of data collection and interpretation that lead to some variability in annual reported volumes. Critical points of uncertainty and the approach used to minimize that uncertainty are described below.
3.4.1 Pond Surfaces A single recorded pond elevation may not be adequate for the purposes of quantifying the amount of FT in ponds where solids are present at the surface of the pond; LIDAR survey is used to determine the top surface of the pond in this case. This is currently the case for the DDA 1 because the date of the LIDAR survey may not align with the nominal date of the pond investigation.
The data is reviewed on a case-by-case basis to minimize potential sources of error. LIDAR measurements of the pond surface, taken close to the date of the survey, are compared to the monitored pond level and the surface elevations taken during the survey. The LIDAR is then used to describe the pond surface if there is no significant difference in the elevations. The LIDAR can be adjusted or a simplified pond surface can be constructed from the surveyed pond elevations taken at the time of the CT09 soundings, if the elevations are significantly different. The LIDAR surface becomes the preferable measurement option because the result of surveyed pond elevations can potentially be at a lower resolution surface.
3.4.2 Date Reconciliation Average nominal survey dates are determined for each pond because pond investigations can take up to a month in larger ponds. This date is then used to linearly interpolate back or project forward to a nominal overall survey date. The adjusted values are then summed to determine the total reconciled volume. In cases where significant FT transfers have occurred; monitoring data is used instead of simple linear interpolation. The following points should be noted:
The volumes presented in this report are date reconciled to June 30, at the end of the reporting period, to allow for simple reporting and to minimize the potential error of trying to reconcile volumes to the end of the calendar year. Fluid Tailings transfers are monitored based on flow density; and reconciling for dilution at the source pond and settling at the destination pond can be challenging.
3.4.3 Transitional Materials Soft materials with strengths on the boundary between soil behaviour and fluid behaviour have been identified on the BBW face of several deposits. CT09 refusal is correlated to a strength of approximately 5 kPa; however, some zones of this soft material with strength up to 10 kPa may be considered “potentially mobile” depending on their location and planned deposition in that area. Canadian Natural therefore flags any soft material between 2 and 10 kPa as “on the boundary” and assess these zones on a case-by-case basis. The specific instances of these materials and how they are interpreted are described in Section 4.1. In order to address uncertainty driven by the presence of this material, a conservative approach is taken. The following points should be noted:
The transitional materials are classified as a separate material for the purposes of characterization and monitoring, but are considered fluid in this report. Pond bottom is sometimes derived from CPT where the CT09 tool may encounter refusal prematurely (e.g., bitumen mats). Additional CPTs are planned wherever this material is expected.
MINE GEOTECHNICAL AND GEOLOGY 14 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 4 MODELLING
Data obtained from the ATI was used to generate the pond bottom surface, mudline surface definitions, and to create a three-dimensional classification of treated tailings, FT, and CWZ for each pond. Figures 5 and 6 illustrate the pond bottom contours and mudlines for DDA 1, SC 1, SC 2, and FC 1, respectively. The profile views of the different tailings zones for the tailings ponds are shown in Figures 7 and 8.
Block models were generated using the surface definitions mentioned above and individual block properties were subsequently estimated using laboratory test results. The block models were then used to quantify the mass of fines in the FT. The results were used to compare to growth estimates that were generated by tailings planning models. This comparison was used to support the annual tracking of fines in each tailings deposit and the determination of the amount of fines in treated tailings and FT. Sections are generated from the block models that show the variability in both solids content and fines content are provided in Figures 9 through 12.
4.1 Pond Bottom and Mudline Interpretation Fluid Tailings volumes were calculated based on Canadian Natural’s tailings measurement guidelines which are consistent with those outlined in the Guideline for Determining Oil Sands Fluid Tailings Volumes (COSIA, 2015) and Section 5 of the Muskeg River Mine and Jackpine Mine Tailings Measurement Plan (Canadian Natural, 2018). Pond bottom surfaces were modelled and reviewed against previous surveys, laboratory sampling, satellite imagery, and any additional available data in an effort to produce a representative fluid inventory. Commentaries relating to the interpretation of the available data are outlined below.
4.1.1 DDA 1 TT Mixed Tailings Deposit The BBW slope of the TT deposit continues to progress farther into the pond as deposition continues. The BBW slope is composed of a material with strengths that indicate soil behaviour overlain by a softer material. This softer material has strengths in a range that can produce inconsistent results with the CT09 tool. Cone Penetration Testing is used to determine the bottom of this soft material, and it is classified as a fluid for the purposes of reporting. For monitoring purposes, this material is classified and modelled as a separate material referred to as the Transition Zone (TZ), as initially identified in 2015. It is suspected that a significant portion of the TZ may be subject to mixing and entrainment into infilled CST material; this continues to be closely monitored until it is determined that it is on a trajectory towards reclamation objectives or meets Ready-to-Reclaim (RTR) criteria.
4.1.2 Centrifuge Product The centrifuge product in DDA 1 was investigated during the ATI. The centrifuge BAW forms in the northwest corner of DDA 1 and data indicates that the centrifuge BBW deposit extends across the southern portion of the pond. The centrifuge product appears to be non-segregating from the point of deposition onto the beach. Investigation in the area of the centrifuge deposition also indicates that centrifuge product is ‘mixing’ with the CST beach being formed along the west side of DDA 1. This mixing process resulted in high fines layers within the CST beach. The nature of this behaviour has led to the following modelling approach.
Pure centrifuge product, both BAW and BBW, has been modelled as FT for 2019 based on continued monitoring and the fact that it did not refuse the CT09 tool.
MINE GEOTECHNICAL AND GEOLOGY 15 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020
Mixed centrifuge product and CST, with similar characteristics to other transitional materials in the DDA 1 were classified as TZ and are currently reported as FT. Mixed centrifuge product entrained in CST beach (creating a fines-enriched sand deposit) is considered beach.
4.2 Mass of Fines Estimation The mass of fines within the fluid bodies and the treated tailings deposits are determined based on an estimation produced through the creation of block models using Maptek’s “Vulcan” engineering software. This section outlines areas of special interest encountered during the process of calculating the mass of fines across the site.
4.2.1 Transition Zone Material The estimation of the mass of fines in the FT is performed assuming that the tailings have settled into essentially uniform horizontal layers. Review of the data in the DDA 1 indicates that the TZ, despite its low strength and fluid-like behaviour, does not form uniform horizontal layers. As a result, the TZ has been estimated separately from the rest of the DDA 1 FT.
4.2.2 Centrifuge Product Entrained in CST Beaches As described in the previous section, an appreciable amount of centrifuge product has been entrained into the CST beaches formed along the west side of DDA 1. Due to the complex geometry of the inter-bedding and mixing, validation of the full block model estimation of the mass of fines entrained within this material is challenging to quantify.
MINE GEOTECHNICAL AND GEOLOGY 16 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 5 TAILINGS DEPOSITS
5.1 Beaching Operations and Performance
Coarse Sand Tailings were deposited in all ponds except FC 1 in 2019, with a focus on DDA 1 and SC 1 during the reporting period. Cell construction was utilized to continue dyke raises and maintain containment as necessary. Design beach lengths were monitored and maintained as specified in the individual dyke designs, and are annually reported on. Ongoing structural performance and construction monitoring are reported to the AER as per the requirements of the dam and canal safety regulatory framework.
As noted previously, beaching operations in DDA 1 are producing a deposit that is characteristically different from beaching operations in other ponds. This has largely been attributed to the presence of centrifuge product and TT and the high ratio of BBW deposition to BAW deposition. This deposition methodology in DDA 1 has resulted in significant fines capture. The extent of the fines capture continues to be evaluated and increased density of investigation is planned in this material to better understand the impact to CST beach performance and site fines capture.
5.2 Centrifuge Deposits Centrifuge deposits are formed through the deposition of centrifuge product. SC 1 is the primary source for untreated FT at JPM and centrifuge product is currently disposed of in DDA 1 exclusively. The following section presents details on the operation of centrifuge product in DDA 1. As the centrifuge RTR criteria has currently not been approved and is subject to alteration, no commentary on performance is provided. Production summaries and monitoring are still provided in Section 8.2.
5.2.1 DDA 1 Centrifuge Operation The centrifuge deposit in DDA 1 is formed via hydraulic deposition from the northwest corner of the pond. The centrifuge product flows and fills a large portion of the pond. The centrifuge product may be subject to mixing with runoff from TT deposition and some FT. Strength gain has been noted as flow ceases and the effects of aging and consolidation begin, and efforts to monitor these effects are ongoing. A significant portion of the centrifuge product appears to be progressively consumed/mixed into the CST beach. As noted previously this material is considered as a fines-enriched sand deposit and is separate from ‘pure’ centrifuge product as both its strength and consolidation behaviours are different.
Pure centrifuge deposit has been included in the FT inventory as per the 2016 FTMP approval condition and the Guideline For Determining Oil Sands Fluid Tailings Volumes (COSIA, 2015). Its properties are therefore also included in the FT model for DDA 1 and are included in Sections J1 through J3 in Figures 9 and 11.
5.3 Thickened Tailings Mixed Deposits Thickened Tailings mixed deposits at JPM are formed from TT slurry mixed with periodic CST deposition in DDA 1.
5.3.1 DDA 1 TT Mixed Deposit Operation and Performance Thickened Tailings are deposited in the northwest corner of DDA 1 (see Figure 2). Coarse Sand Tailings has been deposited into DDA 1 from various locations along the north and west dykes, resulting in the current deposit that is a combination of TT and CST. Thickened Tailings deposition also produced a zone
MINE GEOTECHNICAL AND GEOLOGY 17 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 of treated FT on the BBW slope of the TT deposit that has been classified as TZ. The performance of the TT deposit TZ is being monitored to identify if it is on a trajectory towards reclamation outcomes or meets the required RTR criteria. This material is not included in performance monitoring and is currently accounted in the FT inventory.
Information regarding the TT mixed deposit formed in DDA 1 during the reporting period is included in Table 2. The TT mixed deposit did not account for the entire beach formed in DDA 1 and is approximate because the exact flow patterns of the TT and CST below the pond surface are based on engineering judgment.
Data regarding older deposit already having achieved the required RTR was presented in the 2018 FTMR. Additional data relating to new deposit and monitoring, including observed undrained shear strengths, pore pressures, and effective stress for a representative section of the TT deposit are displayed in the section J2-J2’ provided in Figures 13a through 13e. As per the SIR response submitted to the AER on December 6, 2019, No MBI or information on clay fraction has been provided in this package.

5.4 Atmospheric Fines Drying Deposit Atmospheric Fines Drying (AFD) is a thin lift FT treatment technology. Deposits can be formed in the treatment location or the treated solid tailings can be hauled into dumps.
5.4.1 SC 2 AFD Pilot Deposit Operation and Performance A pilot scale AFD operation was conducted on the beach of SC 2 in the previous reporting period, as per the notification titled “Modified Atmospheric Fines Drying Pilot” provided to the AER April 2, 2018. No additional AFD material was produced at JPM in this reporting period; however, some investigatory work was performed on the AFD material produced in 2018. Details and data regarding this work are provided in the Tailings Research and Development summary provided in Appendix D.
5.5 Settlement and Consolidation Settlement and consolidation are not directly tracked in active deposits. Settlement gauges are installed as deposits reach their ultimate height (at the end of deposition) and direct monitoring of settlements are used for closure designs. During active deposition, settlement and consolidation are monitored by tracking the annual change in solids content (presented in the tables above).

6.6 Settlement and Consolidation Settlement and consolidation of FT are not directly tracked in active ponds due to the complexity and inaccuracy inherent in measuring and calculating these values. Estimations of the impact of settlement and consolidation are produced on a planning level, based on laboratory testing (Large Strain
MINE GEOTECHNICAL AND GEOLOGY 20 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020
Consolidation testing). These laboratory estimates of FT are implemented in planning models to support accurate calculation of CWZ volumes. Effects such as wave action, active dredging, dilution during transport, and the entrainment of coarse material all combine to make any laboratory derived estimate of consolidation have some degree of error. Due to these factors, Canadian Natural has excluded the impact of settlement and consolidation for the purpose of annual reporting, to ensure conservatism in the JPM FTMP, and to provide more reliable long-term estimates of required storage in primary FT storage areas.
MINE GEOTECHNICAL AND GEOLOGY 21 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 7 TAILINGS WATER
The following section provides information regarding management of water at JPM. This includes a water balance, current inventories, and an environmental characterization of pond water. The pond water contains hydrologic water (precipitation and surface runoff), recycled process water, seepage well interception water and water released from both FT and treated tailings deposits during consolidation.
7.1 Site Water Balance Water from the Athabasca River is pumped from the river water pump house to the Raw Water Pond and the Recycle Water Pond, which are located at MRM. In 2019, 18.72 MCM of water from the Athabasca River was used at the Albian site with 12.86 MCM sent to the Raw Water Pond and 5.85 MCM diverted to the Recycle Water Pond. The river water intake is allocated to MRM and JPM usage. The usage split of fresh water was 11.54 MCM allocated to MRM and 7.18 MCM to JPM.
Of the 7.18 MCM of river water allocated to JPM usage, 2.54 MCM was pumped to the Raw Water Pond and the remainder of 4.64 MCM was diverted to the Recycle Water Pond. Of the 2.54 MCM of water from the Raw Water Pond allocated to JPM, 0.39 MCM was designated as tributary re-charge for Jackpine Creek, 0.40 MCM for the JPM Potable Water Treatment Plant (PWTP), and 1.74 MCM for JPM extraction plant usage. The raw water system provides water to the following systems:
Gland water system for JPM and MRM Boiler feed water makeup for JPM Chlorinated boiler feed water makeup for MRM Chlorinated water for ATCO’s cogeneration unit Fire water JPM Potable Water Treatment Plant Exfiltration Gallery
The JPM PWTP supplied 0.13 MCM of potable water for use at MRM.
The recycle water system is designed to maximize the reuse of on-site process affected water to minimize the use and import of fresh water from the Athabasca River. Utilities provide hot and cold recycled water for a variety of uses. 37.41 MCM of water was allocated to JPM from the Recycle Water Pond as hot water for use in the JPM plant in 2019.
Reclaimed water from MRM and JPM tailings are the main water sources for the Recycle Water Pond. A total of 36.67 MCM of water was reclaimed from JPM tailings in 2019 and sent to MRM for reuse. In addition, 16.96 MCM of water was reclaimed from JPM tailings and sent to the JPM extraction plant.
In addition to river import, JPM accounted for the following external sources of water in 2019:
1.72 MCM of water from precipitation and surface runoff 6.97 MCM of water from aquifer depressurization, and seepage well interception wells 3.96 MCM of connate water (i.e., water in ore) which reported to the JPM ore preparation plant
MINE GEOTECHNICAL AND GEOLOGY 22 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020
JPM accounted for the following losses of water in 2019:
1.03 MCM of water evaporated from the JPM tailings based on temperature differentials from CST deposition 4.51 MCM of water transferred from JPM to MRM from the JPM froth sent to the froth treatment plants on the MRM site; this water reports to the TSRU tailings streams for deposition into In-Pit Cell 3
The JPM tailings ponds gained 12.70 MCM of water that includes clear water inventory and water trapped in tailings pore spaces in both the fluid and deposits. ETF seepage of 1.15 MCM water was also directed back to JPM tailings ponds in 2019.
A schematic detailing the 2019 water balance for JPM is provided in Appendix B.
7.1.1 Clear Water Inventory As shown in Table 10, the actual total clear water volume at JPM at the end of 2019 was 16.1 MCM. This was lower than the planned volume of 17.6 MCM from the FTMP submission due to some operational changes. The actual volume of water in FC1 was 7.4 MCM at the end of 2019, versus the planned volume of 0.8 MCM. The actual volume in the ETF, consisting of the DDA 1, SC 1 and SC 2 was 8.7 MCM versus the planned volume of 16.8 MCM.

The JPM seepage water management system that was designed to control the flow of process affected fluid under the ETF was modified and began directing flow to FC 1 in May 2017 (previously was directed to ETF). The water from the Lean Oil Sands Pond and mine water to the Crushing and Conveying Pond and Crusher Sump were directed to FC 1. FC 1 receives water from the Pleistocene Channel Aquifer wells as well as from several Basal and Middle McMurray ground water wells. The FC 1 reclaim water system was commissioned to transfer water to the ETF (DDA 1) in November 2017 to supply water for process requirements.
The primary process water reclaim system was maintained in the ETF in 2019. This system provides reclaim water to the JPM extraction plant and transfers water to the Recycle Water Pond. The water inventory in the ETF increased starting in 2018 to support merging of DDA 1 and SC 1 tailings cells. All tailings deposition in 2019 occurred in the ETF.

7.2 Water Quality Results Water quality samples are periodically taken from the tailings ponds for laboratory testing and annual reporting to the AER. Appendix C presents the average and standard deviation of key characterization analytes of the recycle water pond, reclaim water ponds, and each of the tailings ponds at MRM and JPM. These figures and expanded data and analysis on Albian water quality are published in the 2019 Albian Sands Environment Report (CNRL 2020).
MINE GEOTECHNICAL AND GEOLOGY 24 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 8 EXISTING TAILINGS TECHNOLOGY SUMMARY
Fluid Tailings treatment options are currently being assessed for Canadian Natural’s operations. Details pertaining to treatment options are outlined in the document previously submitted by Shell Canada Limited to the AER titled Jackpine Mine Fluid Tailings Management Plan (SCE, 2016). The two primary strategies for FT management during the reporting period were TT and centrifuge technologies. The following sections describe the annual performance of these strategies.
8.1 Thickened Tailings The TT operation at JPM consists of one thickener that treats hydro-cyclone overflow from the extraction process and forms TT mixed deposits at JPM. DDA 1 exclusively receives the TT slurry.
8.1.1 Thickened Tailings Production Table 11 shows TT slurry volumes for the reporting period.

Table 12: TT Process Monitoring
8.2 Centrifuge Product Centrifuge product is FT dewatered by the centrifugation process. This process extracts water and increases the tailings yield strength, accelerating the process of dewatering required to achieve a solid tailings. Centrifuge product at JPM is currently being produced by four centrifuge units, in operation since 2014, located along the perimeter road west of the DDA 1 (as shown in Figure 2). These centrifuges are fed by FT dredged from SC 1 with the resulting centrifuge product deposited into the northwest corner of DDA 1.

A summary of Canadian Natural’s tailings research has been prepared and is included in Appendix D. The research projects undertaken by Canadian Natural’s Process Innovation group have been designed to provide information to allow the selection of tailings technologies for commercial implementation. Tailings research is also used in the development of Canadian Natural’s tailings plans, including Canadian Natural’s FTMPs, which enables Canadian Natural to explore continuous improvement.
Canadian Natural continues to refine its tailings technologies and depositional strategies. The following efforts were made to improve the state of Canadian Natural’s tailings:
FT Consolidation: Casing Project Soft Deposit Capping: Centrifuge Cake Test Cell Geotube Pilot FT Pressure Filtration Pilot Modified Atmospheric Fines Drying Strategy
Appendix D includes tailings technology research performed in support of tailings operations at MRM and JPM, and excludes any research performed by Canadian Natural for Horizon Mine.
MINE GEOTECHNICAL AND GEOLOGY 27 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 10 ENVIRONMENTAL MONITORING (SUB-OBJECTIVE 2)
In April 2020, Canadian Natural submitted MRM’s 2019 Annual Groundwater Monitoring Report to AER. This report summarized the 2019 groundwater monitoring activities and results for JPM. The objectives of the groundwater monitoring program at JPM is to establish groundwater baseline conditions, evaluate for potential changes in groundwater quantity (groundwater elevations) and groundwater quality (chemistry), and assess the potential impact of JPM on groundwater quantity and quality.
With respect to groundwater quantity, no significant changes were measured during the monitoring period in reference (January to December 2019). The exceptions to this summary are significant drawdowns measured in the basal aquifer, near depressurization wells. These drawdowns are expected to recover when depressurization wells are turned off.
With respect to groundwater quality, the sampling and testing results of the 2019 monitoring period indicate that at the majority of site monitoring wells, no significant variations in groundwater chemistry have been detected, which will require groundwater remediation. Based on the monitoring results, indicator parameters tested in monitoring wells generally fall within the baseline (pre-mine) and historical background chemistry ranges. However, the concentrations recorded at some specific monitoring wells are new highs or lows, which exceed control limits. However, the concentrations recorded at some specific monitoring wells are new highs or lows, which exceed control limits. At these well locations, the groundwater response plan steps will be followed in investigating these variations.
These results indicate that no significant impacts were detected at JPM, during the 2019 groundwater monitoring period.
Hydrogeological monitoring data is collected throughout the site at critical locations to monitor the Environmental impact of mining operations to the groundwater. This data is provided in Appendix E, in line with subject matter requested by the AER in their Supplemental Information Request (December 18, 2019).
Canadian Natural will continue to perform JPM groundwater monitoring and reporting activities, in accordance with the Approval.

A summary of stakeholder engagement activities performed over the reporting period is included in Appendix F and includes engagements performed in support of tailings operations at MRM and JPM.
Also included are responses to stakeholder feedback from the 2018 FTMR.
MINE GEOTECHNICAL AND GEOLOGY 29 Canadian Natural Jackpine Mine Fluid Tailings Management Report AER 2020 12 CLOSURE
This report was compiled by various authors in the various disciplines to meet the requirements of Directive 085. Data collected to inform this report adheres to the procedures and methods described in the Muskeg River Mine and Jackpine Mine Tailings Measurement Plan (Canadian Natural, 2018) and guidelines provided in the Guideline for Determining Oil Sands Fluid Tailings Volumes (COSIA, 2015).
Based on the currently available data, and current projections, JPM continues to be operated based on the plan laid out in the Jackpine Mine Fluid Tailings Management Plan (SCE, 2016).
Ongoing efforts continue to be focused on evaluating the mechanisms responsible for the variability in fines capture observed throughout the site, improving and optimizing the currently operational tailings treatments, and developing novel treatments. A particular focus will be given to fines captured in DDA 1 beach through CST deposition into the centrifuge deposit to better understand mechanisms leading to observed fines capture in that pond. Current progress in these areas indicates JPM will meet the requirements laid out in the Commercial Scheme Approval No. 9756H (as amended).

Fluid Tailings
Fluid Tailings (treated or non-treated tailings) are the discard from bitumen extraction facilities containing more than 5% (mass) suspended mineral solid and having an undrained shear strength less than 5 kPa. The ConeTec CT09 tool is used to determine the approximate hard bottom surface during the ATI.
The 5% solids content mark is defined as the mudline and is determined by using a Geoforte density plate calibrated to a specific gravity of 1.05. Fluid below the mudline is classified as FT.
As accounted in this report, the FT inventory includes some treated material that has not yet exceeded the undrained shear strength requirement.
Clear Water Zone
The CWZ is the supernatant fluid above the mudline. Water above the mudline is recycled to the extraction plant.
Solid Tailings
Solid tailings are fine tailings deposits having an undrained shear strength greater than 5 kPa. Solid tailings at JPM include BBW and BAW deposits formed from the discharge of CST, TT, and WT streams.
Available Storage
Available storage is the volume available between the projected pond and Beach Above Water surface and the planned freeboard elevation for a given period.

C-1 Industrial Wastewater Characterization
Canadian Natural’s industrial wastewater consists of recycled water, seepage water, water from mine dewatering activities, and groundwater from mine pit depressurization activities. Table C1 and Table C2 provides a summary of industrial wastewater holding facilities at Muskeg River Mine and Jackpine Mine, respectively. Wastewaters are stored onsite within a closed-circuit water management system. Water is reclaimed from in-pit cells and the External Tailings Facility (ETF) by a network of perimeter pumps. The wastewater is pumped to the recycle water pond for reuse in plant operations. Seepage water from the ETF is captured in a perimeter ditch, directed into a seepage collection pond, and then pumped back into the ETF. Precipitation and meltwater greatly influence the chemistry of recycled water, as it may spend time in the tailings pond’s perimeter ditching system before returning to the ETF.

Figure C1 presents the average and standard deviation of key characterization analytes of the recycle water pond, reclaim water ponds, and each of the tailings ponds at MRM and JPM. The recycle water pond and reclaim water ponds values are key water quality variables, as is their standard deviation for MRM and JPM recycled water throughout the period of mine operations, from 2010 to 2019.
The water composition of the recycle water pond and each of the tailings ponds at MRM and JPM are included in the Figure C2. The Raw Water Pond (RWP) is used to contrast the compositions of major ions. The RWP is typically much lower than the tailings ponds with the exception of calcium and magnesium.
Figure C1 - Industrial Wastewater Characterization: Tailings Ponds Box Plots, 2006- 2019
Changes of ionic composition in the tailings ponds reflect the composition of the ore being mined. The ionic composition of the RWP is stochastic due to the natural variability in the Athabasca River. Sulphate does appear to be increasing in the tailings ponds.

1.0 FFT Consolidation: Casing Project
1.1 Overview Canadian Natural has been conducting an integrated program of testing, the Tailings Consolidation Casing Experimental Pilot Project (TCCEPP), to measure the consolidation properties that govern storage and settlement of tailings. The initial program included a series of tests to account for the possibility that the size of the test specimen could influence the measured consolidation behaviour. The tests spanned a range of effective stresses and overall sample volumes. The representative properties have been used to scale up modelling to compare the performance of tailings treatment options for field-scale deposits. The field-scale predictions are used to investigate the impact that treatment technologies may have on reclamation objectives (e.g., parameters such as tailings and water volumes, time for consolidation, and the expected amount of settlement).
The current update on the 2019 TCCEPP activities continues the multi-year performance monitoring of the casings. Detailed performance data, including consolidation, is not described in this report, but results will be disclosed in upcoming releases documenting the performance.
1.2 Objective The objective of the TCCEPP is to refine existing assumptions regarding the self-weight consolidation behaviour of various tailings treatments; supported by numerical modelling, the results from this project will enable improved technology selection.
The project will meet this objective by monitoring the performance of the casings through: Increasing deposit thickness beyond those associated with laboratory-scale initiatives, enabling evaluation of consolidation at self-weight stress states approaching those experienced in the field Evaluating scale-up of tailings mixing systems beyond lab scale Providing opportunities to evaluate multiple draining and/or loading scenarios Consolidation modelling sensitivity analysis using various boundary conditions
1.3 Monitoring & Sampling Campaigns The monitoring of each casing continued through 2019 to provide the data needed to evaluate consolidation. Key measurements include fluid level, mudline, pore pressure, total stress and geophysical properties.
Instrumentation data is used in conjunction with manual mudline measurements and data from sampling campaigns to analyze consolidation performance.

1.4 Planned 2020 Activities Performance monitoring of the TCCEPP is planned to continue through 2020 as part of the multi-year monitoring campaign. The resulting data will be used as it becomes available to refine current assumptions about consolidation behaviour and to aid in numerical modelling for various tailings treatments. Furthermore, the TCCEPP's multi-year evaluation provides an opportunity for modifying select casings to evaluate de-watering with under-drains, wicks or other methods, and for the application of surcharges.
Numerical modelling back analysis has been conducted for seven of the eight casings. The consolidation properties have been evaluated and used in the selection of representative compressibility and hydraulic conductivity parameters for the different tailings treatment scenarios. Preparation of the 2019 TCCEPP Monitoring and Performance report is already in progress with the assistance of consultants and is expected to be complete in Q2 2020.

2.0 Modified Atmospheric Fines Drying
2.1 Overview Atmospheric Fines Drying (AFD) has been used at Canadian Natural for several years and is currently one of the FFT treatment technologies in commercial operation. The option of placing flocculated FFT onto tailings beaches and after drying and a full freeze/thaw cycle has been completed placing another lift on top of the previous deposit. In this manner, the high cost of re-handling the dried AFD material to a dump location is minimized as the material is left in place and ultimately becomes part of the dry tailings structure, a process referred to as Modified Atmospheric Fines Drying (MAFD).
In 2018, modified AFD was deposited on the NE portion of the SC 2 BAW area for drying. The depositional behaviour, initial dewatering and atmospheric drying were monitored.
In 2019, samples were collected to determine the effect of the freeze-thaw cycle and the material properties before capping.
In 2020, the MAFD deposit will be capped by coarse sand tailings. Field testing and sampling are planned to determine the capping performance.

3.0 Soft Deposit Capping: Centrifuge Cake Test Cell
3.1 Overview The JPM centrifuge test cell was constructed in the fall of 2015 and filled with centrifuge cake in January 2016. A site investigation was completed in August of 2016, and since the centrifuge cake deposit was not deemed strong enough to support a cap, no additional work was performed in 2016 aside from ongoing dewatering of ponded water within the cell. The activities after 2017 have focused on exploring potential strength and consolidation improvement options.
The centrifuge cake deposit surface was divided into a number of segments, including one control area (blank zone) and other areas that were used for the evaluation of different vegetation species and wick drain installation. The deposit was continuously monitored using the installed instrumentation and regular surveying of settlement plates.
The 2019 field work included the following activities: A vegetation survey, leaf biomass sampling, and root sampling (performed by NAIT) Shallow and deep centrifuge cake sampling and laboratory testing (performed by BGC) Hand vane shear testing and field tensiometer measurements of shallow cake deposit (performed by BGC) In-situ ball penetration testing (BCPT), electronic vane shear testing (eVST) and cone penetration testing (CPT) (performed by ConeTec)

4.0 Geotube Pilot Program
4.1 Overview Canadian Natural is assessing the feasibility of geotubes (or geobags) in the context of creating terrestrial, out-of-pit, reclamation features with treated fluid fine tailings (FFT). Several small scale field trials have been undertaken in the past, culminating with a large-scale demonstration that was completed in the fall of 2018. The objective of the program was to assess and demonstrate the commerciality, including economic feasibility, of geobags in FFT service. Specifically, the following key components were evaluated. Scaling Factors o Assess the effect of geobag size on dewatering performance Stackability o Assess the safety, required conditions and labour associated with stacking geobags Chemical Treatments o Assess the effect of various chemical treatments and mixing arrangements on dewatering performance, geotechnical performance, and release water quality
The program which was conducted at MRM, involved the design, construction, filling, and initial performance monitoring of 11 geobags filled with oil sands fluid fine tailings (FFT) treated with various chemicals (“recipes”). In total, six different recipes were used to treat the FFT. The recipes varied by the coagulant dosage, polymer type and dosage, FFT/chemical mixing arrangement (spool, static or dynamic mixing), and the initial target FFT solids content that was fed to the geobags.
All of the FFT used in the program was sourced from the MRM External Tailings Facility (ETF).
In addition to evaluating different recipes, four different geobag sizes, ranging from pilot small to commercial long, were used in the program. The different sizes were used to evaluate scaling factors related to geobag size. Stackability of the geobags was evaluated by stacking one of the geobags on top of two other geobags.
During pilot operation (i.e. periods of geobag filling), the process was monitored through in-line instrumentation and daily sampling of key process streams. The geobags were also monitored during filling and afterwards through daily geobag height surveying, geotechnical investigations (core sampling and VST), and instrumentation (TPCs, VWPs, and thermistors).
Canadian Natural Tailings Research & Development: Summary of 2019 Tailings Projects 8 Canadian Natural – Muskeg River Mine and Jackpine Mine Summary of 2019 Tailings Projects AER 2020
Throughout the course of the pilot, a total, 6,962 dry tonnes of FFT was treated and poured into the geobags.
Detailed performance data, including field sampling campaigns and determination of dewatering performance and consolidation within the geobags, have continued in 2019. This data will be the foundation of technology performance assessment and a performance report currently being prepared (to be complete by May 2020).
The findings from the performance assessment will be evaluated to decide whether another investigation is necessary for spring 2020, after a second freeze-thaw cycle.

5.0 FFT Pressure Filtration Pilot
5.1 Overview The filter press is a well-known technology that delivers rapid water recovery from fluid fine tailings (FFT) by mechanically pressing water out of the fine clay slurry to form a dense cake suitable for immediate transport to a reclamation area. The added step of chemically treating the FFT before mechanical filtration is a crucial part of the process.
This multi-year project culminated in a large-scale pilot that aimed to deliver the information required to design a full commercial plant, including: the effect of a live and variable FFT feed on the operating parameters and the final products; throughput as defined by filtration cycle times and product quality; optimal chemical amendment dosages, types (flocculation and coagulation) and injection locations; the effect of shear on the treated FFT feed; evaluation of the feed solids concentration and value of partial dewatering of the slurry prior to filtration; testing of the filter cake handling and discharge system; evaluation of the effect of bitumen on the process; evaluation of cloth durability, blinding and lifetime of the cloth; the preliminary capital and operating costs of the technology; and geotechnical evaluation of a large filter cake deposit
5.2 2019 site pilot program The site pilot consisted of two 10 m3 scale presses complete with 100 chambers of two-metre by two- metre area and thicknesses varying from 25, 30, and 35 mm. One of the presses was equipped with a membrane squeeze technology. The plant had multiple options for feed conditioning prior to the filtration step and initial dewatering options.
The main key performance indicators for the site pilot were the cake solids content with corresponding shear strength and the filtrate quality.
The 2019 site pilot program was completed in September 2019. It has provided results and confirmed previous assumptions to inform the commercial design assumptions. In summary, the main findings of the pilot program include (these will be included in the performance report which is currently being written: the FFT filter press technology is reliable and can be operated continuously at a commercial scale;
Canadian Natural Tailings Research & Development: Summary of 2019 Tailings Projects 10 Canadian Natural – Muskeg River Mine and Jackpine Mine Summary of 2019 Tailings Projects AER 2020
chemical treatment of the FFT feed (flocculation and coagulation) is required for the success of the technology; there was no significant effect of shearing the feed (using a centrifugal pump) on the produced cake or filtrate observed; the minimum filtration pressure requirements of 700 kPa was confirmed (the use of the membrane squeeze did not add significant benefit) production cake consistently reached 60% solids content with 45 min. of press time (one hour cycle time); and the deposit material placed was immediately trafficable with a D6 dozer
The pressure filtration technology is able to immediately produce “upland reclamation ready” products from FFT.
Solids content achieved in the filter press cakes ranged from 50-70% by weight throughout the project. An average of 63% solids by weight was achieved over the ~215 runs performed over July and August 2019. The corresponding in-situ peak shear strength ranged from 15 to 40 kPa, measured with an electronic field vane.
The advantage of the filter press technology is the production of a final product suitable for earthworks. There will be minimal additional consolidation of these deposits. The quality of the filtrate was very good in terms of low total suspended solids; however, due to the addition of coagulant, it may require chemical treatment depending on the final destination of the filtrate stream.
Detailed factual and performance reports are currently being written with the help of Barr Engineering. The reports are scheduled to be available to the public in May 2020.

TECHNICAL MEMORANDUM
Date: April 28, 2020 Subject: Supplemental Information - 2019 Annual Tailings Management Reports for MRM and JPM Revision: Rev. 2 From: Bernard Dzirasah, P.Geo., M.S., M.Sc., B.Sc. Mine Hydrogeologist, Canadian Natural, Albian Sands.
Reviewer Gary Baldwin, P.Eng. & P.Geol., Lead Geologist, Canadian Natural, Albian Sands.
APEGA PERMIT NUMBER: P6872
1.0 TERMS OF REFERENCE 1. Canadian Natural Upgrading Limited, CNUL, (Canadian Natural) is majority owner and operator of Muskeg River Mine (MRM) and Jackpine Mine (JPM). MRM and JPM operate under the Environmental Protection and Enhancement Act (EPEA) Approval Numbers 20809-02-00 and 00153125-01-00 respectively (as amended). The MRM and JPM operations also fall under Directive 085 (Fluid Tailings Management for Oil Sands Mining Projects). 2. Following CNUL’s submission of the “2018 Annual Tailings Management Reports for MRM and JPM”, in April 2019 (under Directive 085), the Alberta Energy Regulator (AER) issued revised supplemental information requests (SIRs) on hydrogeology on December 18, 2019 (Attachment 1), in line with AER’s meeting with the Canadian Association of Petroleum Producers (CAPP) held on November 18, 2019. CNUL provided the requested information in a technical memorandum dated January 31, 2020. 3. This technical memorandum is intended to provide supplemental information to the AER regarding the subject matter covered in the December 18, 2019 SIRs. This memorandum accompanies CNUL’s “2019 Annual Tailings Management Reports for MRM and JPM”.
2.0 MRM SUPPLEMENTAL INFORMATION
In line with AER’s SIRs issued on December 2019, regarding monitoring well location map, rationale for design of monitoring network, monitoring data, and a statement as to whether the RTR objective are being met, CNUL provides the following supplemental information:
The requested map is shown in Figure 1-1.
Supplemental Information - 2019 Annual Tailings Management Reports for MRM and JPM Page 1 of 3
CNUL’s monitoring well network is designed for holistic monitoring of the MRM mine pit (and its backfill content) as a whole, rather than for each individual in-pit cell. To this end, the monitoring well network has individual wells targeting each aquifer beneath or around the mine pit as a whole (Basal aquifer and Quaternary aquifer), as approved under EPEA. In-pit Cells 1, 2 and 3 (IPC1, IPC2, and IPC3) are treated tailings deposits located within the MRM mine pit, Figure 1-1, separated by in-pit dykes. Since the monitoring well network is designed to monitor the mine pit (as a whole), the same monitoring well network monitors each deposit. This design provides suitable monitoring and evaluation of RTR status, given that monitoring covers all potential contaminant migration paths for the entire backfilled mine pit. This approach is effective for long term environmental monitoring, in that, even if the initial anticipated contaminant flow directions for each deposit was not accurately predicted, or technology changes result in different mining or tailings deposition methods, or if changes in groundwater gradients result in change in flow directions, the mine pit monitoring network will remain equally effective.
The requested summary table is presented in Tables 1A, 1B, 1C and 1D, updated with the most recent 2019 monitoring results.
Table 1A presents the chemistry results for hydrocarbons. Hydrocarbons are potential sources of contaminants within treated tailings. For this reason, hydrocarbons are identified under EPEA as contaminants of potential concern. Therefore, hydrocarbon concentrations are monitored in groundwater around the in-pit cells (mine pit), including downgradient locations. Based on the groundwater monitoring results (Table 1A), hydrocarbons are generally non- detect (see laboratory results preceded by “<”), or detected at low concentrations below Alberta Tier 1 Soil and Groundwater Remediation Guidelines. Based on Table 1A, there are no trends or exceedances of limits set under the project’s EPEA approval, with respect to hydrocarbons.
Table 1B presents the chemistry results for dissolved metals. Dissolved metals are potential sources of contaminants within tailings. For this reason, dissolved metals are identified under EPEA as contaminants of potential concern which must be monitored. Based on the groundwater monitoring results (Table 1B), dissolved metals are generally non-detect (see laboratory results preceded by “<”), or detected at low concentrations, except in few cases where concentrations are naturally higher than Alberta Tier 1 Soil and Groundwater Remediation Guidelines (see yellow highlighted values in table). These exceptions are natural, and can be seen in some results collected at initial data. Based on Table 1B, there are no trends or exceedances of limits set under the project’s EPEA approval, with respect to hydrocarbons.
Table 1C presents the chemistry results for routine parameters and select indicators (including select metals and hydrocarbons). Significant changes in routine parameters such as pH could indicate potential impacts. For this reason, routine parameters are identified for monitoring under EPEA. Based on the groundwater monitoring results (Table 1C), these constituents are detected at low concentrations, except in some cases where the concentrations are higher than Alberta Tier 1 Soil and Groundwater Remediation Guidelines (see yellow highlighted values in table). These are largely due to naturally high concentrations in the baseline or localized natural hardwater precipitates in some wells. Based on Table 1C, there are no trends attributable to tailings impacts, and the fluctuations in some routine parameters do not pose limitations to reclamation or RTR status of the treated tailings in IPC1, IPC2, and IPC3.
Table 1D presents field-measured parameter results for sampling programs associated with Tables 1A through 1C. The table indicates that some of the Quaternary wells on the east side of tailings cells (IPC1, IPC2, and IPC3) have sometimes been dry, either preventing sampling altogether or allowing sampling low water volumes that may be higher in concentration with respect to natural hardwater mineral precipitates.
Based on out groundwater chemistry results, IPC1, IPC2, and IPC3 deposits are still meeting RTR criteria with respect to groundwater conditions.

3.0 JPM SUPLEMENTAL INFORMATION In line with AER’s SIR’s issued on December 2019, regarding monitoring results, compliance and concluding statement as to whether RTR objectives are being met, CNUL provides the following supplemental information:
While the process-affected water (PAW) indicator parameters tested in the shallow and deep Quaternary seepage management system (SMS) wells in the ETF area were within the baseline (pre-ETF) chemistry ranges, there were some variations within the upper and lower ends of the range, some of which exceeded the mean, and trend toward the higher ends of the range. In accordance with the site’s EPEA approval, control limit exceedances call for investigation (including verification, confirmation, delineation, quantification and mitigation/remediation). The control limit exceedances mentioned in the annual groundwater report did trigger increased monitoring (for verification), but there are no confirmed or delineated groundwater impacts. We note that the JPM ETF has a seepage management system designed (as approved), which is operated to mitigate any seepage or fluctuations in groundwater parameters. Such fluctuations in some groundwater parameters are common and do return to within control limits, as the seepage management system is operated to extract seepage. So that, no groundwater impacts are identified at this time. In particular, the control limit exceedances indicated have been attributed to naturally occurring phenomena, emanating from the natural hardwater precipitates of calcite and gypsum, as stated in the results interpretation section of the annual report referenced. For example, we noted control limit exceedances in monitoring well SH06-4030B, with respect to calcium and sulphate. But this well’s water is naturally supersaturated with respect to the minerals calcite (calcium carbonate) and gypsum (calcium sulphate), which often precipitates on well screens naturally, as is the case in hardwater environments. Specifically, in 2018, calcium levels in the ETF (potential SOURCE of contaminants) ranged from 42-55 mg/L; but the calcium levels in monitoring well SH06-4030B is as high as 370 mg/L (see Table 1E), which is at least six (6) times the values at the ETF source. A 42-55 mg/L source could not cause a 370 mg/L contamination, further supporting natural precipitates in the well, rather than a contaminant plume from the ETF. Similarly, in 2019, calcium levels in the ETF ranged from approximately 50-59 mg/L (see SC1 and SC2 results, Table 1E); but the calcium levels in monitoring well MW10-001C is as high as 206 mg/L (Table 1E), which is at least three (3) times the values at the ETF source. A 50-59 mg/L source could not cause a 206 mg/L contamination, further supporting natural occurrence. The well water is naturally higher than the potential SOURCE, in these cases. Based on the groundwater monitoring results in reference, the treated tailings deposits in the JPM ETF still meet RTR criteria with respect to groundwater conditions.

Canadian Natural Upgrading Ltd. Muskeg River Mine – 2018 Annual Tailings Management Report Supplemental Information Request – Hydrogeology
Dear Mr. Wytrychowski:
The Alberta Energy Regulator (AER) met with the Canadian Association of Petroleum Producers (CAPP) on November 18, 2019 to review the hydrogeology-related question of the Oil Sands 2018 Annual Tailings Management Report Supplemental Information Requests, originally issued in industry on September 13, 2019.
The following question replaces Question No. 9 from the Supplemental Information Request. In order for the AER to continue its review of the 2018 submission. The AER requires a response from Canadian Natural Upgrading Ltd. (CNUL) by January 31, 2020,
1. CNUL provided some groundwater monitoring results for the External Tailings Facility (ETF) at Muskeg River Mine, however information was not provided for the IPC1, IPC2, and IPC3 treated tailings deposits. The AER requires additional information to complete the groundwater review for the 2018 annual report.
Operator measurement system plans detailing groundwater monitoring commitments for ready to reclaim (RTR) deposits have not undergone detailed review by the AER. However, in order to monitor environmental performance of treated tailings, the operator is required satisfy subobjective 2 and must provide a summary of groundwater conditions for all current deposits containing treated tailings reported as achieving RTR status (deposit) within the Annual Fluid Tailings Management Report, Section 6.2, Environmental Monitoring Results page 25.
a. The summarized results for ICP1, ICP2 and ICP3 must include:
i. a map of each deposit identifying the location(s) and name(s) of the groundwater monitoring well(s) designed to identify any groundwater contamination from each respective deposit, or
If the deposit is not monitored individually, rationalize why monitoring results for multiple deposits, or contaminant sources, will provide suitable data required for the evaluation of RTR status for that specific deposit.
ii. a table summarizing the groundwater quality results downgradient of the deposits identified in part (i). Identify trends and any exceedances of limits set under the project’s EPEA Approval.
1
iii. a clear statement, referencing the table in ii, and conveying if the deposits are still meeting RTR criteria with respect to groundwater conditions.
If you have any questions, contact Eric Chiu at (403) 297-2889 or [email protected].
Sincerely,
Eric Chiu cc: Hannah LaPlante, AER

MINE GEOTECHNICAL AND GEOLOGY Canadian Natural 2019 MRM and JPM Fluid Tailings Management Report April 2020
Stakeholder Engagement
On October 10, 2019, Canadian Natural held a one‐day technical tailings forum with Indigenous stakeholder communities to discuss the 2018 Annual Fluid Tailings Management Reports (TMR) submitted to the Alberta Energy Regulator (AER) on April 30, 2019, for Muskeg River Mine (MRM) and Jackpine (JPM). Based on feedback from the 2018 tailings engagements, Canadian Natural held one collective multi‐ stakeholder Tailings Forum instead of meeting individually with each stakeholder as in 2018. Stakeholders included in the 2019 Tailings Forum were identified as those having a Sustainability Agreements or Community Building Agreements with MRM and JPM, or were invited to the Horizon Tailings Forum to continue alignment across Canadian Natural.
The Stakeholder communities commissioned various consultants or representatives to review the MRM and JPM 2018 TMRs and attended the forum on their behalf. The following stakeholder communities were represented:
Athabasca Chipewyan First Nation (ACFN) Fort Chipewyan Métis Local #125 (ML #125) Fort McKay First Nation (FMFN) Fort McKay Métis Nation (formerly Fort McKay Métis Community Association / Fort McKay Métis Local #63) (FMMN) Fort McMurray Métis Local #1935 (ML 1935) Fort McMurray #468 First Nation (FMFN#468) Mikisew Cree First Nation (MCFN) The 2019 Tailings Forum was held in Fort McMurray and focused on providing an overview of the information in the MRM and JPM 2018 TMRs and answering questions Stakeholders had on tailings management. As previously communicated to Stakeholders, in the Agenda, sent prior to the forum, the information presented was Directive 085 focused. Additional questions/topics out of the scope of Directive 085 brought forward by Stakeholders were either discussed or Canadian Natural agreed to respond later.
Information presented during the forum included: Overview of the MRM and JPM 2018 Annual TMRs; Current Tailings Activities at MRM and JPM including pond status, fluid profile and ready‐to‐ reclaim criteria for both the external tailings facilities and in‐pit storage facilities; Site wide water accumulation and water management; and Update on ongoing tailings technology research and tailings development areas.
During the forum, a list of action items and concerns were maintained. The forum participants collectively reviewed the list at the end of the meeting. Any outstanding concerns that were not addressed during the forum were recorded and followed‐up at a later time.
Following the 2019 Tailings Forum, Canadian Natural requested feedback on forum format and structure. A copy of the forum’s minute notes were also provided to Stakeholders for approval and/or comment.

Following the forum, each consultant also prepared a report for the communities that included additional questions and request for information regarding MRM and JPM tailings management and other environmental concerns. These reports were submitted to Canadian Natural to address. Canadian Natural will respond to the reports with a technical memo to Stakeholders.
Stakeholder’s concerns and feedback from the forum and Canadian Natural’s responses are included in Table C‐1. Stakeholder feedback received specifically on the 2018 TMRs have been included in Table C‐1.

Is radiation monitoring performed around tailings? Canadian Natural does conduct Naturally Occurring Radioactive Materials (NORM) testing around tailings ponds specifically when there is a TSRU deposit (NORMs have not been identified in any other tailings material to date). If the deposit material is wet/saturated, there is no concern for NORM and once TSRU material is capped there is no concern. Currently all sites of concern on the MRM ETF have been capped and the areas along the access road are all under the threshold for NORMs.
