1. 1.    Introduction

The Dust Management Plan describes the measures used by Canadian Natural Upgrading Limited (Canadian Natural) to mitigate dust emissions at Muskeg River Mine (MRM) and Jackpine Mine (JPM). The Dust management plan and has been prepared to comply with the Alberta Environmental Protection and Enhancement Act (EPEA):

• Approval 20809-02-00, Condition 4.1.44-45; and
• Approvals 00153125-01-00, Condition 4.1.49-50.

In general, the two conditions require the plan identify and describe the sources and activities at each mine site which have the potential to cause dust particles to be suspended in the air. It also describes the actions taken to monitor and minimize dust emissions and the effectiveness of existing dust control strategies.

The Dust Management Plan has been developed considering current Best Management Practices (BMP) in the Oil Sands Region. The Dust Management Plan is subject to on-going review and utilizes adaptive management principles, which require updates to the plan as appropriate.

The adaptive management approach includes:

• clearly defined management objectives to guide decision-making
• exploring alternatives to meet management objectives
• predicting the outcomes of alternatives based on the current state of knowledge
• implementing one or more of these alternatives
• monitoring to learn about the impacts of management actions
• using the results to update knowledge and adjust management actions.

1.1  Background

Canadian Natural MRM and JPM are located about 70 km north of Fort McMurray, Alberta and approximately 500 km northeast of Edmonton. Fort McKay is the closest community, located about 5 km west of the MRM and 15 km west of JPM. Both MRM and JPM consist of an open pit mine, tailings storage areas, bitumen processing and associated infrastructure.

The predominant features in the area are the Athabasca River which runs north to south and the Muskeg River running from the northeast to the southwest and connecting to the Athabasca River south of Fort McKay. Both rivers are surrounded by wide river valleys. The elevation of the mines range from approximately 275 to 325 meters above sea level. Vegetation in the area

3

consists primarily of aspen, poplar, white spruce and jack pine in upland areas and black spruce, tamarack, and willow in wetland areas. The terrain is level to undulating.

Temperatures average -19°C during the winter months and +17°C during the short summer season. Annual average precipitation is 456 mm that falls mainly in the summer months. The average annual snowfall is 156 cm, with snow covering the landscape five to seven months of the year. Precipitation is highest from May to September, with an average of 62.5 mm per month during this period.

Prevailing winds in the area are predominantly from south–southwest and north–northeast, as reported from the Wood Buffalo Environmental Association’s (WBEA) ambient air monitoring station number 9 (AMS9). Though both valley features surrounding the mines are broad and the hills are several kilometers away, the features have the potential to disrupt wind flow patterns and channel the flow in the direction of the valley. Given the mines’ position in the Muskeg River valley, a strong north-west to south-east trend is observed at the onsite wind monitoring station presently operating at the Project. This trend, combined with the north to south wind trend resulting from the Athabasca River valley are likely to influence dispersion of air emissions.

1.2  Canadian Natural’s Environmental Policy

Environmental protection is a fundamental value of Canadian Natural. This dust management plan incorporates the core values of Canadian Natural’s environmental policy and is within the framework of Canadian Natural’s Environment Management System (EMS).

• Provide strong leadership and promote a participative culture to proactively identify, assess and manage environmental risks and associated impacts;

• Strive to reduce the impacts of our activities through adaptive management while considering social and economic factors;

• Reduce the environmental footprint of our activities by continually improving energy efficiency, managing greenhouse gases, air emissions, water use and other resources; reduce and recycle waste materials and preserve and restore natural biodiversity through closure planning and reclamation;

1. 2.    Identification of Potential Sources

2.1  Dust Characterization

Dust consists of particles with small aerodynamic diameters (ranging from 1 -100 µm) originating from natural or anthropogenic sources that are suspended into the atmosphere under various conditions. Fugitive dust is among the largest fractions of PM2.5 and PM10 (particles with diameter less than 2.5 µm and 10 µm, respectively) emissions in Alberta (Environment Canada, 2014).

Wind speed, temperature, precipitation, humidity, and indirectly soil moisture content can influence the amount of particulate material suspended in the atmosphere. The distance travelled by dust emissions will depend on the particle size, wind speed, and turbulence. Smaller dust particles will stay airborne for longer periods and disperse over a wider area. Strong and turbulent winds will also keep larger particles airborne for longer periods of time.

Depending on its composition, suspended dust particles can have potential adverse effects on the air, water, vegetation, and human health.

2.2  Dust Generation

Fugitive dust particles suspended in the air can result from windblown generated dust or mechanically generated dust. Windborne dust occurs when there is turbulent air on erodible surfaces because of the wind’s velocity reaching a specific threshold. Mechanically generated dust is a result of the pulverization and abrasion of surface material due to mechanical force such as vehicle traffic.

Weather conditions have a major impact on the amount of dust mobilized. Precipitation, temperature, and evaporation conditions can affect the moisture of the material being disturbed and have an indirect effect on the amount of dust generated. Dust generation is more prevalent in the summer and fall months when conditions are dry and windy. During the winter, the roads

5

are frozen with dust particles bound in the surface. Thawing and rainfall in the spring maintains the moisture in the road surfaces and limits the emission of dust particles in the air.

2.3  Dust Sources and activities generating fugitive dust

In general, the dust generating mechanisms are:

1. Wind Erosion

Wind-generated dust occurs when wind speed exceeds the erosion threshold velocity of the underlying surface. Under these conditions, large particles are dislodged by shear forces and move and creep across the surface. These particles, by their movement, or skipping motion, can dislodge smaller particles, which then remain suspended in the air. The surface impacts also re-arrange the surface exposing new particles that may contribute further to this process.

1. Material Handling

Mechanical material handling processes generating dust include movement such as loading and unloading, screening operations, dropping operations such as conveyor transfer points, stacking and reclaiming. The amount of dust generated from these processes is usually not primarily dependent on the wind speed. The highest dust levels occur downwind under light wind conditions where dust plumes are relatively undispersed.

1. Vehicular Movement

Wheel / track generated dust occurs when the road surface is impacted by the passage of vehicles (mine equipment and light vehicles) and loosened particulate matter is uplifted by the turbulent air behind the vehicle. Heavy vehicles and high speeds will produce higher emissions than light vehicles and low speeds. This effect is enhanced when vehicles are travelling over roads with heavy particulate loading, usually around areas where unsealed roads intersect sealed roads (paved).

The dust exposure areas and location of dust emission concerns at MRM and JPM are listed below (a map of locations is provided in Appendix A: Dust Emission Sources Map):

• Haul roads
• Paved roads
• Unpaved utility roads
• Tailings storage areas
• Mine stripped areas (vegetation and organic soils removed)

6

• Mine pit
• Overburden stockpiles
• Reclamation material stockpiles
• Aggregate quarry areas

2.3.1  Road Dust

Active mining areas are a major source for dust emissions, as they are open pit mines that, in addition to altering the wind patterns, expose surfaces to wind erosion by removing vegetation. Within the active mining areas, heavy haul trucks and other large mining equipment exert a great degree of force on the haul roads resulting in the pulverization and abrasion of surface material creating road dust.

Unpaved utility roads are also a source of dust emission. The vehicle size, speed, and the number of vehicles on the road all influence the amount of dust generated. Smaller, lighter vehicles generate less dust emissions than heavier equipment that exert a greater force on the road. The heavier and faster a vehicle moves the more dust that will be generated. Even without vehicle traffic, wind-borne dust will become airborne if the road surface is dry and the wind speed is high. Although paved surfaces are expected to generate limited dust, dust can be generated if debris such as clay and gravel accumulate on the roadway.

2.3.2  Tailings Storage Areas (External Tailings Facility and In Pit Tailings Storage)

Tailings material is wet during disposition and is maintained wet due to continuous elevation of the tailings water level. Fine-grained particles in the tailings material are suspended in the fluid and are normally submersed; therefore not readily affected by wind erosion. Although the beach areas above the water level have the potential to dry out, these areas are mainly coarse sand material, which has minimal potential to be suspended in the air.

Similar to other unpaved roads within the mining areas, roads on top of the tailings dykes at JPM and MRM can emit dust because of vehicle traffic and drier conditions.

2.3.3  Overburden and Reclamation Material Stockpiles

Surface disturbance during the stripping of overburden and reclamation material has the potential for dust to be emitted. In addition, the transport and placement of the material can result in dust generation. Once stockpiled, dust can be generated by wind velocities that suspend particles in the air.

7

2.3.4  Aggregate Mining Areas

The MRM Sharkbite area contains a gravel pit that provides sand and gravel for road and dyke construction activities at MRM and JPM. Sand and gravel extraction including gravel crushing and conveying release dust into the air. In addition, stockpiles of this aggregate material can be a source of dust if wind velocities suspend particles in the air.

1. 3.    Dust Control and Mitigation

Various dust control measures can mitigate dust generation at the source although not all dust mitigations have the same effectiveness. Table 2 provides a list of common dust control measures and their effectiveness.

Table 2: Dust Control Measures Efficiencies

Source: US EPA, AP-42, 5th Edition “Compilation of Air Pollutants Emission Factor, Volume 1: Stationary Point and Area Sources”

As outlined in Table 3, MRM and JPM use various control measures to minimize dust emissions. Each mitigation measure is focused on reducing dust particles being emitted into the air and/or reducing activities that generate dust.

Table 3 – Muskeg River Mine and Jackpine Mine Dust Mitigation

3.1  Surface Watering

Surface watering to minimize surface disturbance is a key control method to mitigate dust emissions at MRM and JPM. Increasing the moisture content of unpaved roads and gravel piles binds the finer material together forming larger, heavier particles that are less likely to become airborne. Both MRM and JPM use water trucks in the active mine areas, gravel aggregate areas and around the plant site to maintain adequate moisture content. The effectiveness of surface watering is dependent on environment factors, including humidity levels and wind speed in addition to traffic volume and vehicle size and speed on the roads. Mine haul roads and unpaved utility roads are sprayed twice daily with water during the dry summer and fall months and more frequently during dry and windy conditions.

3.2  Control of vehicle traffic

At MRM and JPM, restricted vehicle traffic and enforcement of speed limits on haul roads and other unpaved and paved roads throughout the mine sites are used to reduce dust emissions. Depending on the environmental conditions (hot temperatures and high winds) and potential for excess dust emissions, haul road speed limits are further reduced when required.

9

3.3  Road Design and Maintenance

Proper construction of haul roads are an important consideration for effective dust control. At MRM and JPM, haul roads are structurally designed to withstand the impact of heavier equipment and to reduce road degradation both of which can lessen the potential for fine particle exposure and dust emissions. In addition, equipment is designated each shift for maintaining road conditions. Debris on paved roads is removed as required using road cleaning and street sweeping equipment.

3.4  Material Handling

At MRM and JPM movement of overburden and reclamation material is managed to minimize handling. Suitable overburden material is used in dyke construction while material not suitable for dyke construction is used for road construction or stored in overburden disposal areas for future reclamation. Overburden disposal areas and Reclamation Material Stockpiles (RMS) are strategical located as to reduce the haul distance from the active stripping area. In addition, most of the reclamation material salvage operations are conducted during the winter months on frozen down roads further reducing the potential to mobilize dust.

During dyke and overburden disposal area construction, dust generation is controlled through compaction of surface material. To aid in erosion control, portions of structures are also assessed for progressive reclamation as construction continues to final elevation. Stockpiles not in use after one year are assessed for revegetation.

3.5  Reclamation

Reclamation material such as subsoil, topsoil and peat is salvaged and stored in accordance to the EPEA Approval’s 00153125-01-00 and 20809-02-00, as amended. Reclamation material is either directly placed onto the landform or stockpiled for future use as outlined in the Annual Reclamation Progress Tacking Reports, submitted to the Alberta Energy Regulator (AER) in April of each year. At JPM and MRM, Reclamation Material Stockpiles (RMS) rely on natural regrowth to provide a rooting mat control to restrict erosion. This technique of encouraging natural vegetation not only returns additional seed stock, but also acts as dust control.

Canadian Natural will proceed with progressive reclamation at MRM and JPM as individual landforms are no longer required for the operation.

3.7 Chemical suppressants

At this point in time, chemical dust suppressants are not used at MRM and JPM. However, SOILTAC, a soil stabilizer and dust control agent, has been an internally approved Safety Data

10

Sheet (SDS) dust suppressant that can be used at Canadian Natural if required and appropriate. SOILTAC is a milky white liquid (transparent once cured) that can be deployed to control dust, erosion, and stabilize soil. Industries that utilize this chemical include construction, mining, military, municipal, oil and gas, and transportation. The SDS classifies SOILTAC as not dangerous for the environment.

Canadian Natural requests that SOILTAC and water be authorized by the Director to use at MRM and JPM for dust control, if and when required, as per clause 4.1.47 (MRM) and clause 4.1.52 (JPM). SOILTAC would be used when conditions require a higher level of control and the volumes and locations will be reported in the EPEA annual report. If any additional dust suppressants or chemicals are intended to be used on roads or lands for the purpose of dust management, Canadian Natural will submit an authorization request in writing to the Director prior to use.

1. 4.    Dust Monitoring and Contingency Plan

PM2.5 particulate matter, of which fugitive dust is one source, is measured continuously at WBEA’s AMS 9. Located along the southwest edge of MRM between the mine and Ft. MacKay, any exceedance of ambient air quality objectives (Alberta Environment and Parks, Ambient Air Quality Objectives) is reported immediately to Canadian Natural and appropriate regulatory agencies. Canadian Natural is required to follow up on the verbal report with a written report detailing site conditions, potential sources, and mitigation measures employed. In addition, WBEA publishes an annual report detailing the monitoring results for all stations in their network that is submitted to required regulatory agencies.

PM10, PM2.5 and Total (less than 100 µm) Particulate Matter (TPM) are reported annually to the National Pollutant Release Inventory (NPRI).

Dust emissions are monitored within the mine and plant site areas by visual assessment. Visual assessments of key source areas are completed twice daily during summer and fall months and occur more frequently during dry and windy conditions. When current mitigation measures are identified to be insufficient during visual assessments, contingency actions will be taken to mediate dusty conditions. Contingency actions include more frequent surface watering, addition of an authorized chemical suppressant, further reduced vehicle speed, and reduced or ceased material handling activities. Surface watering activities are recorded on the Site Services daily shift log.
