EXECUTIVE SUMMARY The ACA management zone contains a region parallel to the Edmonton Census Metropolitan Area as shown in Figure 1 of the main report. The air monitoring network consists of a continuous monitoring network, an intermittent particulate monitoring network, and a passive monitoring network. Figure 2 of the main report presents the locations of the continuous air monitoring stations. The ACA management zone contains nine continuous monitoring stations. The continuous network measures sulphur dioxide (SO2), hydrogen sulphide (H2S), nitrogen oxides (NO, NO2, NOx), carbon monoxide (CO), ozone (O3), total hydrocarbons (THC), methane (CH4), non‐methane hydrocarbon (NMHC), particulate matter (PM2.5 and PM10), ambient temperature (ET), relative humidity (RH), wind speed (WS) and wind direction (WD). In 2013, the annual instrument uptime for the continuous monitoring parameters exceeded 90% requirement of the Alberta Air Monitoring Directive (AMD), with the exception of 89.5% for PM2.5 at the Edmonton South Station. Table ES‐1 summarizes the annual average concentrations for the year of 2013. There were seven (7) exceedance events for H2S, as well as twenty‐five (25) exceedance events for PM2.5. The Sherwood Park, Gold Bar, Beverly, and Woodcroft stations also measure 24‐hour intermittent samples for particulate matter every six days following the sampling schedule of the National Ambient Pollution Surveillance Network (NAPS, Environment Canada). The intermittent monitoring program measures 24‐hour average concentrations for PM2.5, PM10, and TSP using dedicated air samplers. Table ES‐2 summarizes the monitoring results for 2013. There were four (4) exceedance events for 24‐hour average PM2.5 in 2013. The Woodcroft station also recorded four (4) exceedance events for 24‐hour average TSP, attributed to construction activities near the station. The ACA passive network includes six monitoring sites as shown in Figure 3 of the main report. Each site monitors 30‐day average concentration for SO2, NO2, and O3. Table ES‐3 summarizes the annual average concentrations results for 2013. There were no exceedance events in 2013.

1.0 Introduction The Alberta Capital Airshed (ACA) is a not‐for‐profit, multi‐stakeholder organization that is looking forward to monitor and provide public information on air quality, as well as to develop recommendations regarding air quality management and monitoring. In addition, ACA facilitates dialogue among the community, industry, and government for managing air quality within an area that parallels the Edmonton Census Metropolitan Area (see Figure 1). ACA is one of nine airsheds in Alberta, who together serve as an air monitoring partnership for Albertans. One of ACA’s primary roles is to gather the information from air quality monitoring conducted by other groups (e.g., municipal, industry, institutions) and ensures all stakeholders, including the public, has access to it.

1.1 ACA Mission and Vision ACA Vision: Residents within the Alberta Capital Airshed region live, work, and play in a safe and healthy environment with clean air that has no measurable short or long term adverse effects on people, animals or the environment. ACA Mission: To provide easily accessible, high quality data and expertise vital to develop comprehensive air quality management plans – clean air solutions that keep our air clean.

1.2 ACA Air Monitoring Network The ACA air monitoring network includes a continuous monitoring network, an intermittent particulate monitoring network and a passive monitoring network. The ACA management zone currently contains nine continuous air monitoring stations. The air monitoring stations are operated by the Strathcona Industrial Association (SIA), Lehigh Cement Ltd. and Alberta Environment and Sustainable Resource Development (AESRD). Figure 2 illustrates the locations of the continuous monitoring stations. The measured air quality parameters are summarized in Table 1. Among the continuous monitoring stations, the Sherwood Park, Gold Bar, Beverly, and Woodcroft stations also measure 24‐hour intermittent samples for particulate matter every six days following the sampling schedule of the National Ambient Pollution Surveillance Network (NAPS, Environment Canada). The intermittent monitoring program measures fine particulate matter (PM2.5) at all four stations. In addition, the Woodcroft station also measures inhalable particulate matter (PM10) and total suspended particulate matter (TSP). The ACA passive monitoring network consists of six sampling sites operated by the SIA. Figure 3 illustrates locations of the passive monitoring sites. Each site measures 30‐day average for SO2, NO2, and O3. Passive samples are collected on a monthly basis.

2.0 Summary of Air Monitoring Data

2.1 Summary of Exceedances above the AAAQO’s The ACA air monitoring network measures air pollutant concentrations to indicate the general quality of air in the airshed zone. Ambient air quality data is used to investigate the trends in air quality resulting from emissions of anthropogenic sources (industry, motor vehicles, etc) and natural biological processes (such as forest fires, decomposition of organic matter, etc). Table 2 summarizes the number of exceedances above the Alberta Ambient Air Quality Objectives (AAAQO) for the year 2013. For the continuous monitoring network, there were seven (7) exceedance events for 1‐hour H2S, and twenty‐five (25) exceedance events for 24‐hour PM2.5. The H2S exceedance events were recorded at the Beverly and Gold Bar stations. The PM2.5 exceedance events were primarily recorded in the winter, with the exception of three (3) exceedances in May and two (2) in August. The winter exceedances could be associated with impaired dispersion conditions when the atmosphere was stable, such as during a temperature inversion. For the intermittent monitoring network, there were four (4) exceedance events for intermittent 24‐hour PM2.5 and four (4) exceedance events for 24‐hour TSP. The PM2.5 exceedance events were attributed to a winter temperature inversion; the TSP exceedances at the Woodcroft station were attributed to construction activities in the nearby gravel parking lot.

2.2 Wind Data Summary Wind speed and wind direction are important factors that influence regional air quality. The diffusion and dispersion of air pollutant emissions are greatly impacted by variations in wind speed and corresponding air turbulence. Different degrees of turbulence are created by variable mixing conditions due to the vertical gradient of ambient temperatures and terrain roughness unique to each station. Figure 4 presents the wind roses at the ACA continuous monitoring stations. The prevalent winds in this area were primarily from the southern sectors, and to a lesser frequency from the northwest directions. The Elmjay station typically recorded a higher wind speed than the other stations, potentially due to the open, flat terrain near this station. The detailed frequency distribution table and wind roses are presented in Appendix I: AMD Summary Tables.

2.3 Continuous Air Quality Data

2.3.1 Sulphur Dioxide (SO2) Sulphur dioxide is a colourless, non‐flammable gas with a pungent odour. Natural sources include volcanoes, biodegradation of organic matter, and solar action on seawater. The primary anthropogenic sources of SO2 include fossil fuel combustion, petroleum refining, and smelting sulphide ores. Exposure to SO2 results in numerous effects to the pulmonary system. Healthy subjects exhibit increased airway resistance and bronchoconstriction, decreased maximum expiratory flow and decreased pulmonary function. Asthmatic subjects exhibit similar symptoms but also report increases in asthma symptoms, wheezing, chest tightness, and difficulty breathing. Sulphur dioxide affects vegetation as a result of acute and chronic exposures. Acute exposure to high concentrations of sulfur dioxide can produce injury in the form of foliar necrosis. Long term exposures to low concentration of SO2 have been shown to affect metabolic activity. The current Alberta Ambient Air Quality Objectives (AAAQO) for sulphur dioxide are:

• 1‐hour average AAAQO = 172 ppb • 24‐hour average AAAQO = 48 ppb • annual average AAAQO = 8 ppb

Table 3 presents the summary statistics for 1‐hour average concentrations for SO2 for the ACA monitoring stations. The annual average concentration was 1 ppb. The maximum 1‐hour average concentration of 76 ppb and the maximum 24‐hour average concentrations of 19 ppb were both recorded at the Beverly station. Table 4 summarizes the number of exceedances of the Alberta Ambient Air Quality Objectives. There were no exceedance events for the 1‐hour, 24‐hour, and annual average concentrations in 2013. Figures 5 to 11 present pollutant roses for 1‐hour average SO2 for the ACA monitoring stations. The pollutant roses indicate that SO2 concentration was predominantly less than 5 ppb. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that more than 90% of the time the 1‐hour average SO2 concentration was less than 5 ppb. Figure 12 compares the annual average SO2 concentrations for fifty‐two (52) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 5th, 6th, 8th, 11th, 20th, 22nd and 32nd places. A higher concentration tends to be recorded in the areas with heavy industry and energy operation facilities.

2.3.2 Hydrogen Sulphide (H2S) Hydrogen sulphide is a colourless, flammable gas that can be identified by humans at relatively low concentrations. It is characterized by a rotten egg odour. Hydrogen sulphide is extremely hazardous and toxic. The gas occurs naturally in coal pits, sulphur springs, gas wells, and biodegradation of sulphur‐containing organic matter. It is commonly existent in places such as sewers, sewage treatment plants, and manure stockpiles. Industrial sources of hydrogen sulphide include petroleum and natural gas extraction and refining, pulp and paper manufacturing, rayon textile production, leather tanning, chemical manufacturing, and waste disposal. Hydrogen sulfide is a highly toxic and flammable gas. It is heavier than air and tends to accumulate at the bottom of poorly ventilated spaces. Although very pungent at first, it quickly deadens the sense of smell. Potential victims may be unaware of its presence until it is too late. The current AAAQO for hydrogen sulphide are:

• 1‐hour average AAAQO = 10 ppb • 24‐hour average AAAQO = 3 ppb

Table 5 presents summary statistics for 1‐hour average concentrations for H2S for 2013. The annual average concentrations for H2S ranged between <1 ppb and 1 ppb. The highest 1‐hour average concentration of 14 ppb was recorded at the Beverly station. The highest 24‐hour average concentration of 3 ppb was recorded at all stations. Table 6 summarizes the number of exceedance events for the year 2013. There were seven (7) exceedance events for 1‐hour AAAQO. The exceedance events were detected at the Beverly station and Gold Bar station: • The Beverly station detected six (6) exceedance events for 1‐hour average H2S. During the exceedance events,

wind speed was low (<4km/hr), generally from southwest and south‐southwest directions. • The Gold Bar station detected one (1) exceedance event for 1‐hour average H2S. During the exceedance event,

wind speed was calm (<1km/hr), from the north‐northeast direction. Figures 13 to 17 present pollutant roses for 1‐hour average H2S. The pollutant roses indicate H2S concentration in the ambient air was predominantly less than 1 ppb at all stations. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 90% of the time the 1‐hour average H2S concentration was less than 1 ppb, with the exception of the Beverly station (84.3%), and the Sherwood Park station (76.8%). Figure 18 compares the annual average H2S concentrations for eighteen (18) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 3rd, 4th, 6th, 10th, and 14th places.

2.3.3 Nitrogen Dioxide (NO2) Nitrogen dioxide is a reddish‐orange‐brown gas with an irritating, pungent odour. Nitrogen dioxide is corrosive, highly oxidizing and non‐combustible. Nitrogen dioxide occurs naturally in the environment as a result of forest fires, atmospheric lightning discharges, and biodegradation of nitrogen containing compounds. Anthropogenic sources of NO2 are mainly from combustion processes, such as vehicles emissions, coal combustion, and industrial processes. Acute exposure to NO2 of 2 ppm or lower can cause airway inflammation and alterations in lymphocytes appearance in healthy individuals; individuals with asthma have a greater sensitivity to acute exposures. Pre‐exposure to NO2 can increase the responsiveness of mildly asthmatic individuals to inhaled allergens. The effects on vegetation are dependent on a number of factors, for example sensitivity of the species, duration and concentration of the exposure, and stage of growth when exposed. Some of the effects that have been observed include: increase in shoot to root ratio, which results in drought susceptibility; decreased growth; increased shoot nitrogen, which leads to increased susceptibility to pathogen and insect attack; and advanced bud‐break, which could lead to frost damage. The current AAAQO for nitrogen dioxide are:

• 1‐hour average AAAQO = 159 ppb • annual average AAAQO = 24 ppb

Table 7 presents the summary statistics for 1‐hour average concentrations for NO2 for 2013. The annual average concentrations ranged between 11.4 ppb to 18.0 ppb. The maximum 1‐hour average concentration of 118.1 ppb was detected at the Edmonton East station. The maximum 24‐hour average concentration of 58.9 ppb was detected at the Edmonton Centre station. Table 8 summarizes number of exceedances for the year of 2013. There were no exceedance events recorded in the ACA monitoring network. Figures 19 to 24 present pollutant roses for 1‐hour average NO2. The pollutant roses indicate NO2 concentration was predominantly less than 30 ppb at all stations. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 85% of the time the 1‐hour average NO2 concentration was less than 30 ppb, with the exception of the Edmonton Centre station (83.8%). Figure 25 compares the annual average NO2 concentrations for forty‐three (43) monitoring stations in Alberta. The concentrations for the ACA air monitoring stations were ranked high among the stations. Four of the ACA monitoring stations were ranking among the top five stations in the province (1st, 3rd, 4th, and 5th), with the exception of the Sherwood Park station in 10th place, and the Edmonton South station in 11th place. A higher concentration of NO2 tends to be recorded in large cities due to traffic emissions, as well as industrial areas where more combustion sources are present.

2.3.4 Ozone (O3) Ozone is a highly reactive, colourless gas that is normally present in the troposphere as a result of naturally occurring photochemical and meteorological processes. It has a sharp odour that can often be detected around running electric motors, after lightning storms, and newly mown hay. The effects of ozone are dependent on where it exists. Stratospheric ozone protects the earth from UV light, but ozone can be toxic in the troposphere. Ground level ozone is formed through complex chemical reactions between precursor pollutants, e.g. volatile organic compounds and nitrogen oxides, in the presence of heat and sunlight. Changing weather patterns also contribute to yearly variations in ozone concentrations. Ozone also can be transported into an area from pollution sources hundreds of miles upwind. Potential short‐term effects for ozone exposure include pulmonary function reductions, increased airway sensitivities, and airway inflammation. The primary short‐term injury is to the lungs, which is characterized by lung congestion, fluid build‐up, and bleeding. Inhalation may initiate, accelerate, or exacerbate respiratory tract disease of bacterial or viral origin. Discomfort to individuals may involve coughing, dryness of throat, mucous membranes, and of the nose and eyes following exposures of high concentrations for short duration. The current AAAQO for ozone is:

• 1‐hour average AAAQO = 82 ppb Table 9 presents the summary statistics for 1‐hour average concentrations for O3 for 2013. The annual average concentrations ranged between 18 ppb to 25 ppb. The maximum 1‐hour average concentration of 72 ppb and the maximum 24‐hour average concentration of 51 ppb were both detected at the Edmonton South station. Table 10 summarizes the number of exceedances for the year of 2013. There were no exceedance events recorded in the ACA monitoring network. Figures 26 to 29 present pollutant roses for 1‐hour average O3. The pollutant roses indicate O3 concentration in the ambient air was predominantly less than 40 ppb at all stations. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 85% of the time the 1‐hour average O3 concentration was less than 40 ppb, with the exception of the Edmonton South station (84.1%). Figure 30 compares the annual average O3 concentrations for thirty‐two (32) monitoring stations in Alberta. The concentrations for the ACA air monitoring stations were low in the province. The annual average concentrations of the ACA monitoring stations were ranked the 20th, 24th, 26th and 31st places. A lower concentration of O3 tends to be recorded in the areas that have more anthropogenic emission sources, indicating the effects of ozone titration.

2.3.5 Carbon Monoxide (CO) Carbon monoxide is a colourless, odourless, and tasteless gas that is slightly lighter than air. In the presence of oxygen, carbon monoxide burns with a blue flame, producing carbon dioxide. Carbon monoxide is produced from the partial oxidation of carbon‐containing compounds. It forms when there is not enough oxygen to produce carbon dioxide, such as when operating a stove or an internal combustion engine in an enclosed space. Carbon monoxide is toxic to humans and animals when exposed at high concentrations. Carbon monoxide mainly causes adverse effects in humans by combining with hemoglobin to form carboxyhemoglobin in the blood. This prevents hemoglobin from releasing oxygen leading to hypoxia. Exposures to a high concentration can lead to significant toxicity of the central nervous system and even death. Symptoms of mild acute poisoning include light headedness, confusion, headaches, vertigo, and flu‐like effects. Chronic exposure to low levels of carbon monoxide can lead to depression, confusion, and memory loss. The current AAAQO for Carbon monoxide are:

• 1‐hour average AAAQO = 13 ppm • 8‐hour average AAAQO = 5 ppm

Table 11 presents the summary statistics for 1‐hour average concentrations for CO. The annual average concentration was 0.2 ppm. The maximum 1‐hour average concentration of 1.6 ppm was detected at the Edmonton South station, and the maximum 8‐hour average concentration of 1.1 ppm was detected at the Edmonton Centre station. Table 12 summarizes the number of exceedances for the year of 2013. There were no exceedance events recorded in the ACA monitoring network. Figures 31 to 33 present pollutant roses for 1‐hour average CO. The pollutant roses indicate CO concentration in the ambient air was predominantly less than 1 ppm. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 99% of the time the 1‐hour average CO concentration was less than 1 ppm. Figure 34 compares the annual average CO concentrations for eleven (11) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 2nd, 5th, and 9th places. A higher concentration of CO tends to be recorded in large cities, indicating a potential link with traffic emission sources.

2.3.6 Hydrocarbons (THC, CH4, and NMHC) Hydrocarbons refer to a broad family of chemicals that contain carbon and hydrogen atoms. This includes a number of organic compounds. Sources of hydrocarbons include vegetation, natural biological processes, industrial emissions, transportation, and leisure activities. The total hydrocarbon analyzers employed in the ACA network are unable to differentiate individual hydrocarbon compounds and are limited to the total hydrocarbons (THC) and non‐methane hydrocarbons (NMHC). Currently, there is no ambient air quality objective in Alberta for these hydrocarbons. The typical background THC concentration in Alberta has been reported between 1.9 to 2.4 ppm. Table 13 presents the summary statistics for 1‐hour average concentrations for hydrocarbons. The annual average THC concentrations ranged between 2.0 ppm and 2.4 ppm. The maximum 1‐hour average concentration of 10.3 ppm was detected at the Edmonton East station, and the maximum 24‐hour average concentration of 5.2 ppm was detected at the Beverly station. Methane was the major component of THC for the ACA stations; non‐methane hydrocarbons (≤ 0.2 ppm annual average) only accounted for less than 10% of THC. Figures 35 to 39 present the pollutant roses for 1‐hour average THC. The pollutant roses indicate THC concentration in the ambient air predominantly ranged between 1 ppm to 3 ppm. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 99% of the time the 1‐hour average THC concentration was less than 3 ppm, with the exception of the Beverly station (92.5%) and the Edmonton East station (94%). Figures 40 and 41 present the pollutant roses for 1‐hour average CH4. Because CH4 is the major component of THC, the pollutant roses are similar to THC roses. CH4 concentrations primarily ranged between 1 ppm to 3 ppm. The concentration distribution tables (Appendix I: AMD Summary Tables) indicate that greater than 99% of the time the 1‐hour average CH4 concentration was less than 3 ppm. Figures 42 and 43 present the pollutant roses for 1‐hour average NMHC. The pollutant roses indicate that NHMC concentration in the ambient air was predominantly less than 1 ppm. The concentration distribution tables (Appendix I: AMD Summary Tables) indicate greater than 95% of the time the 1‐hour average NMHC concentration was less than 1 ppm. Figure 44 compares the annual average THC concentrations for thirty‐two (32) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 4th, 14th, 15th, 18th and 26th places. The WBEA area detected the highest THC concentrations in the province.

2.3.7 Particulate Matter (PM2.5 and PM10) Airborne particulates are tiny pieces of solid or liquid matter suspended in the atmosphere. Respirable particulates are fine particles that have the potential to affect human health. Particles with aerodynamic diameters between 2.5 and 10 micrometers are generally removed from inspired air in the nose and throat. Particles that are smaller than 2.5 micrometers (PM2.5) can penetrate into the lungs and are generally referred to as respirable or fine particulate matter. Particles that are between 2.5 microns and 10 microns are generally referred to as inhalable or coarse particulate matters. The total mass concentration of the fine and coarse portions is referred to PM10, or particulate matter smaller than 10 microns aerodynamic diameter. These particles may originate from soil, road dust, agricultural dust, smoke, forest fires, traffic emissions, and industrial sources. Alberta does not have an ambient air quality objective for PM10. The current AAAQO for PM2.5 is:

• 24‐hr average AAAQO = 30 μg/m3 Table 14 presents the summary statistics for 1‐hour average concentrations for particulate matter. The annual average PM2.5 concentrations ranged between 6 µg/m

3 and 11 µg/m3. The maximum 1‐hour average concentration of 449 µg/m3 and the maximum 24‐hour average concentration of 76 µg/m3 were both detected at the Edmonton East station. The ACA network monitors PM10 at the Edmonton South station. The annual average PM10 concentration was 13 µg/m3. Both the maximum 1‐hour average (136 µg/m3) and the maximum 24‐hour average (54 µg/m3) were detected on May 6, 2013. Table 15 summarizes the number of exceedances for the year of 2013. There were twenty‐five (25) exceedance events for 24‐hour PM2.5 for the ACA monitoring program. The PM2.5 exceedance events were primarily recorded in the winter, with the exception of three (3) exceedances in May and two (2) in August. The winter exceedances could be associated with impaired dispersion conditions when the atmosphere was stable, such as during a temperature inversion. Figures 45 to 48 present pollutant roses for 1‐hour average PM2.5. The pollutant roses indicate PM2.5 concentration in the ambient air was predominantly less than 20 µg/m3 at all stations. The detailed pollutant data is presented in Appendix I: AMD Summary Tables. The concentration distribution tables indicate that greater than 90% of the time PM2.5 concentration was less than 20 µg/m

3. Figure 49 presents a pollutant rose for 1‐hour average PM10. The pollutant rose indicates PM10 concentration in the ambient air was predominantly less than 30 µg/m3. The concentration distribution table for PM10 indicates that 91.6% of the time, the 1‐hour average PM10 concentration was less than 30 µg/m

3. Figure 50 compares the annual average PM2.5 concentrations for thirty‐seven (37) monitoring stations in Alberta. The annual average concentrations of the ACA monitoring stations were ranked the 1st, 6th, 16th, and 21st places.

2.4 Air Quality Health Index Air Quality Health Index (AQHI) is a health protection tool that is designed to help the public make decisions to protect their health by limiting short‐term exposure to air pollution and adjusting their activity levels during increased levels of air pollution. The AQHI uses readings from three air pollutants to calculate a single numerical value to evaluate the health risk associated with air pollution. The three pollutants are fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ground‐level ozone (O3). All three pollutants are required to calculate AQHI. Figure 51 illustrates the risk categories and the health messages for the AQHI system. The health risk is classified in four categories: Low (1 to 3), Moderate (4 to 6), High (7 to 10), and Very High (higher than 10).

Figure 51. Risk classification and health messages for Air Quality Health Index

(Environment Canada)

52

Figure 52 compares the AQHI rating among the communities in Alberta. For the City of Edmonton, the ambient air quality was rated Low Risk for 81% of the time; 18% was rated Moderate Risk, 0.7% was rated High Risk, and 0.1% was rated Very High Risk. The Very High Risk rating occurred on May 20, May 21, May 22, and October 25. These Very High Risk events were characterized by a high concentration of fine particulate matter (>250 μg/m3). In Alberta, the High Risk and Very High Risk ratings were primarily recorded in the population centres and Wood Buffalo area. Edmonton recorded the highest percentage of time in the Very High, High and Moderate Risk categories.

2.5 Air Quality for Canadian Cities The air quality for the twenty most populated metropolitans in Canada are compared for SO2, NO2, CO, O3, PM2.5

and PM10 using the NAPS database (NAPS, 2012). It should be noted that the land use types and the number of the stations in the database vary among the cities. The comparison is based on the available data, and is not intended to justify the quality of air among the cities. Figures 53 to 58 compare the annual average concentration for the cities. The bar charts are arranged in a descending order by city population from left to right. An empty bar indicates the city does not have data in the NAPS database. Figure 53 compares the annual average concentration for SO2. The annual averages ranged from 0.2 to 4.3 ppb. The annual average SO2 concentration in Edmonton (0.8 ppb) was ranked 8th. The three highest concentrations were recorded at Hamilton (4.3 ppb), Windsor (2.8 ppb), and Halifax (2.2 ppb). Figure 54 compares the annual average concentration for NO2. The annual averages ranged from 5.6 to 15.2 ppb. The annual average NO2 concentration in Edmonton (13.9 ppb) was ranked 3rd. The two highest concentrations were recorded at Vancouver (15.2 ppb) and Toronto (14.7 ppb). Figure 55 compares the annual average concentration for O3. The annual averages ranged from 14.6 to 28.7 ppb. The annual average O3 concentration in Edmonton (21.6 ppb) was ranked 17th. The three highest concentrations were recorded at St. Catherines (28.7 ppb), St. Johns (28.5 ppb), and Windsor (28.0 ppb). Figure 56 compares the annual average concentration for CO. The annual averages ranged from 0.18 to 0.44 ppm. The annual average CO concentration in Edmonton (0.25 ppm) was ranked 8th. The three highest concentrations were recorded at Winnipeg (0.44 ppm), Regina (0.28 ppm), and Saskatoon (0.27 ppm). Figure 57 compares the annual average concentration for PM2.5. The annual averages ranged from 4.1 to 11.1 µg/m3. The annual average PM2.5 concentration in Edmonton (8.2 µg/m3) was ranked 3rd. The two highest concentrations were recorded at Calgary (11.1 µg/m3) and Montreal (9.3 µg/m3). Figure 58 compares the annual average concentration for PM10. Only six cities reported PM10 data to NAPS. The annual averages ranged from 5.6 to 27.3 µg/m3. The annual average PM10 concentration in Edmonton (12.8 µg/m3) was ranked 3rd. The two highest concentrations were recorded at Regina (27.3 µg/m3) and Calgary (17.9 µg/m3).

2.6 Passive Sample Summary Passives samples are a measure of loadings accumulated over a pre‐determined exposure period. The adsorbed analytes are extracted and analyzed in a laboratory, and calculated to the concentrations in the air. For passive samples, Alberta regulates SO2 only. The current AAAQO for passive SO2 is:

• 30‐day average AAAQO = 11 ppb

The ACA Passive Network consists of six stations monitoring 30‐day averages for SO2, NO2, and O3. In 2013, a total of seventy two (72) samples were collected for SO2, NO2, and O3. There were no sample failures. Table 16 summarizes the annual average and maximum 30‐day concentrations for 2013. Figure 59 presents a time‐course chart for 30‐day average concentration for passive SO2 samples. The 30‐day average concentrations ranged between <1 ppb and 4 ppb. There was no exceedance of the 30‐day average AAAQO in 2013. There was no clear temporal trend or spatial trend detected in the passive monitoring network. Figure 60 presents a time‐course chart for 30‐day average concentration for passive NO2 samples. The measured concentrations ranged between 1.5 ppb and 21.9 ppb. A seasonal trend for NO2 seems to be existent. A higher concentration tended to occur in the winter months. The trend could be associated with the atmospheric conditions. In winter when the air temperature is colder, air pollutants tend to stay longer and accumulate to a higher concentration. In addition, there is a higher chance of forming a thermal inversion layer on cold winter days. Thermal inversion limits atmospheric mixing and caps air pollutants near the ground, forming a higher concentration at the ground level. Figure 61 presents a time‐course chart for 30‐day average concentration for passive O3 samples. The measurements ranged between 10 ppb to 39 ppb. The chart indicates O3 concentration tended to be higher during the spring months. The concentration of ground‐level ozone is the net result of atmospheric formation, transport, and destruction processes. Some research for the Edmonton Capital Region suggests intrusion of ozone from the stratosphere could be an important source of ground‐level ozone. During spring and summer, vertical mixing is stronger and may promote downward propagation of upper air ozone to the ground. However, the Ground‐Level Ozone in Alberta (AESRD, 1999) report suggests that there were split opinions for relative importance of contributions from upper air intrusion, local photochemistry, and the medium and long‐range transport.

2.7 Intermittent Particulate Sample Summary The ACA air monitoring network measures intermittent PM2.5 samples at four stations: Sherwood Park, Gold Bar, Beverly, and Woodcroft. In addition, the Woodcroft station also measures PM10 and total suspended particulate (TSP). The sampling program follows the NAPS sampling schedule. A 24‐hour intermittent sample was collected every six days throughout the year. In 2013, there were sixty one (61) sampling days, resulting in a total of one hundred eighty three (183) samples. There were three (3) failure samples at the Sherwood Park station. A total of one hundred eighty (180) valid samples were collected. Table 17 presents summary statistics for 24‐hour average concentrations for the ACA intermittent particulate monitoring program. There was no significant difference for the annual average PM2.5

concentrations among the four stations. The maximum 24‐hour average concentration was detected on November 6, 2013 at the Sherwood Park station. Figures 62 and 63 present the time‐course chart for 24‐hour average concentrations for 2013. Table 18 summarizes the number of exceedances for the year of 2013. There were three (3) PM2.5 exceedance events detected on March 29, 2013 at the Sherwood Park, Gold Bar, and Beverly stations, attributed to a winter temperature inversion in the region. There was one (1) PM2.5 exceedance event at the Sherwood Park station on November 6, 2012. There were four (4) exceedance events for 24‐hr average TSP at the Woodcroft station. These exceedances were primarily due to construction activities in the nearby gravel parking lot.
