Environment Canada has been monitoring ambient air in the oil sands region for polycyclic aromatic compounds (PACs) since December 2010. Ambient air samples collected using the established protocols and schedule of the National Air Pollution Surveillance (NAPS) program are termed active PAC samples. Active sampling is done at three sites (Mannix [AMS5], Lower Camp [AMS11] and Fort McKay South [AMS13], Alberta). Ambient air concentrations in the oil sands region can be used to evaluate regional differences in PAC concentrations and can be compared with levels of PACs measured in other parts of Canada and to ambient air quality objectives.
Air emissions from oil sands development can come from a number of sources including industrial smokestacks, tailings ponds, transportation, and dust from mining operations. Air quality monitoring under the Joint Canada-Alberta Implementation Plan for the Oil Sands is designed to determine the contribution of emissions from oil sands activities to local and regional air quality and atmospheric deposition both now and in the future. Ambient air quality data include:
Filter Pack (24-hour integrated concentrations of particle-bound SO2-4, NO-3, Cl-, NH+4, Ca2+, Mg2+, Na+, K+ and gaseous SO2 and HNO3 collected daily by the Canadian Air and Precipitation Monitoring Network)
Total Gaseous Mercury (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network and Prairie and Northern Region)
Atmospheric speciated mercury (Hg) (2-hour average concentrations of gaseous elemental Hg (GEM), reactive gaseous Hg (RGM), and Hg on PM2.5 (total particulate Hg - TPM)
Comprehensive set of measurements collected from an aircraft (various time resolutions) covering an area of 140,000 km2 over the oil sands region
Comprehensive set of measurements collected from the Fort McKay Oski-ôtin monitoring site
Ozone (hourly mixing ratios measured by the Canadian Air and Precipitation Monitoring Network)
Ozone Vertical Profiles (ozone mixing ratios as a function of height) measured by the Canadian Ozone Sonde Network
Aerosol Optical Depth (measure of the degree to which the presence of aerosols in the atmosphere prevents the transmission of light, from the ground to the top of the atmosphere) measured as part of the AErosol RObotic CANadian (AEROCAN) network
Satellite overpass data have a relatively high spatial resolution over the Oil Sands region to produce images and geo-referenced data of nitrogen dioxide (NO2) and sulphur dioxide (SO2) “vertical column density” (which correlates with surface concentration)
Air emissions from oil sands development can come from a number of sources including industrial smokestacks, tailings ponds, transportation, and dust from mining operations. Air quality monitoring under the Joint Canada-Alberta Implementation Plan for the Oil Sands is designed to determine the contribution of emissions from oil sands activities to local and regional air quality and atmospheric deposition both now and in the future. Source emission data include:
Compiled and assessed information from existing emissions inventories to enhance the quality of high resolution forecasts and simulations of air quality in the oil sands region;
Estimates of potential emissions to the air from tailings ponds analysed for reduced sulphur compounds (RSC), volatile organic compounds (VOC) and odour perceptibility.
Environment and Climate Change Canada has been monitoring ambient air in the oil sands region for polycyclic aromatic compounds (PACs) using passive air samplers since November 2010. Ambient air samples collected using the established protocols of the Global Atmospheric Passive Sampling (GAPS) Network are termed passive PAC samples. Passive samplers are deployed for two-month periods across a network of 17 sites that are maintained by the Wood Buffalo Environmental Association. Average PAC levels across the passive sampling sites in the oil sands region are comparable to urban/sub-urban levels across Canada and are elevated compared with background rural sites in Canada.
Assess the importance of atmospheric deposition of contaminants as a contributor to ecological impacts of oil sands development and identify sources.
• Use snowpack measurements sampled across a gridwork to develop maps of winter-time atmospheric contaminant loadings for the region ~100 km from the major upgrading facilities
• Assess long-term trends in winter-time atmospheric deposition
• Determine the potential impact of wintertime snowpack mercury loads on tributary river water mercury concentrations (Spring Freshet) using Geographic Information System and hydrological modelling approaches
• Compare snowpack loadings to those obtained from precipitation monitoring and compare spatial patterns to PAC air measurements obtained from passive sampling network
Lake sediment cores were collected from several locations in Canada as part of the historic mercury and heavy metal deposition trend, analysis, and research component of the Clean Air Regulatory Agenda/Climate Change and Air Pollutant (CARA/CCAP) and Oil Sands Monitoring (OSM) programs. The reason sediment core analysis is used for research purposes is the bottom of a lake can act as a record of the contaminants and all other materials which have fallen into the lake over time. The lake water acts as both a sorting device and as a preservative since the deposits fall in chronological order and if not subject to dredging are not normally otherwise disturbed by humans. In areas where depositional histories are complex, including changing contributions from local, regional and global sources, multiple dated lake sediment cores are useful tools for examining response of not only aquatic ecosystems, but their surrounding landscapes through time to changing emission/deposition scenarios.
Environment and Climate Change Canada (ECCC) has been monitoring trace metals in fine particulate matter (PM2.5) in the oil sands region since December 2010. Active PM2.5 sampling is collected at the Wood Buffalo Environmental Association (WBEA) Air Monitoring Stations: Mannix (AMS5), Lower Camp (AMS11) and Fort McKay South (AMS13; until March 2015), using the established protocols and schedule of the National Air Pollution Surveillance (NAPS) Program. In 2015, sampling began for PM2.5 and PM10-2.5 (coarse fraction) at the Fort McKay (AMS1), Wapasu (AMS17) and Stony Mountain (AMS18) sites. The data from the measurements conducted so far show that concentrations of metals decrease with distance from the main surface mining and upgrading activities, and that the crustal elements iron, silicon, aluminum, and calcium are present in greater abundance than other metals detected.
This Joint Oil Sands Monitoring Air Emissions Inventory (Inventory) for the oil sands region is part of the Joint Oil Sands Monitoring Program Emissions Inventory Compilation Report (Report). The Inventory is based on a synthesis of available information from several existing inventories and related emissions data sources compiled up to October 31, 2014. The Inventory also includes input files for the Sparse Matrix Operator Kernel Emissions (SMOKE) emissions processing system, in order to allow users to create gridded input emissions files for air quality modelling. This Inventory was developed to enhance the quality of Environment and Climate Change Canada’s high resolution forecasts and simulations of air quality in the oil sands region.
Patterns of wet deposition of the nitrate/sulfate/ammonium ion across eastern Canada and the United States are based on measurements of precipitation depth and nitrate/sulfate/ammonium concentrations in precipitation samples. These measurements were collected and quality controlled by their respective networks: in Canada, the federal Canadian Air and Precipitation Monitoring Network (CAPMoN) and provincial or territorial networks in Alberta, New Brunswick, the Northwest Territories, Nova Scotia, Ontario and Quebec. In the United States, wet deposition measurements were made by two coordinated networks: the National Atmospheric Deposition Program (NADP) / National Trends Network (NTN) and the NADP/Atmospheric Integrated Research Monitoring Network (AIRMoN). Total annual deposition from each site was screened for completeness using the following criteria: (1) Precipitation amounts were recorded for >90% of the year and >60% of each quarter, and (2) a nitrate/sulfate/ammonium concentration was reported for >70% of the precipitation measured over the year and for >60% of each quarter.
Concentrations of Polycyclic Aromatic Hydrocarbons and Total Petroleum Hydrocarbons in Tailings Pond Water in the Oil Sands Region – September 2013
To evaluate evaporation from tailings ponds as a potential source of emissions of pollutants to air, bulk water samples were collected from 8 locations in two ponds at a single facility in the oil sands region over two days in September 2013. Chemical measurements of polycyclic aromatic hydrocarbons (PAHs) and total petroleum hydrocarbons (TPH) were made. PAH data are reported for the sixteen species identified as priority pollutants by the US EPA. TPH refers to the total amount of hydrocarbon compounds.
