2.0 The Canadian Ambient Air Quality Standards

The Canadian Ambient Air Quality Standards (CAAQS) are national ambient air quality standards intended to protect human health and the environment (Table 3). The CAAQS form the driver for the Air Quality Management System (AQMS), a comprehensive approach to protect and improve ambient air quality. The CAAQS were developed through a collaborative process with the federal government, provincial governments, territorial governments and stakeholders under the direction of the Canadian Council of Ministers of the Environment (CCME). Provincial and territorial governments establish local air zones and identify air monitoring stations to report on the achievement status of the CAAQS in air zones; these stations are referred to as CAAQS reporting stations. Provincial and territorial governments are responsible for:

Monitoring air quality within each air zone;

Evaluating and reporting air quality against the CAAQS metrics;

Assigning management levels to each air zone; and

Planning and implementing air quality management actions where needed. Table 3 PM2.5 and Ozone Canadian Ambient Air Quality Standards

2.1 The CAAQS Management Levels and Thresholds

Associated with the CAAQS are thresholds which can inform management actions intended to keep clean areas clean and continuously improve environmental conditions. The management levels and thresholds for PM2.5 and ozone are illustrated in Table 4. Management levels are assigned to air zones based on metrics calculated from the data collected at the ambient air monitoring stations within each zone. The metric for each standard is introduced in Table 3 and discussed in Section 4.1. Table 4 CAAQS Management Levels and Thresholds

3.0 Alberta Air Zones and CAAQS Reporting Stations

3.1 Alberta Air Zones

Alberta is divided into six air zones (Figure 1) which are aligned with the Province’s Land Use Framework regional boundaries (Alberta Environment and Parks, 2015b). Ambient air quality in Alberta is monitored at continuous air monitoring stations located within these air zones.

3.2 CAAQS Reporting Stations

Provinces and territories use data from a number of continuous stations to conduct the CAAQS assessment and report on the achievement status of the standards and management levels in air zones. Thirty-nine ambient monitoring stations are included in these assessments for Alberta (see Table D1 in Appendix D). Guidance for data used to conduct assessments includes data from stations located in large population centres (population ≥100,000) and those stations that are thought to be regionally representative. PM2.5 and ozone monitoring stations in Alberta have a number of objectives. The following criteria identify which of these monitoring stations will not be used for CAAQS reporting:

sites within areas of industrial activity;

sites which are very near to industrial activities except those used or accessed by members of the public and/or near population centres;

special study sites; and

background sites with no history of anthropogenic influence.

4.0 CAAQS Assessment Methodology

4.1 CAAQS Metrics

The standards have an associated time-averaging period and a statistical form which is described by the metric. Measured concentrations of PM2.5 and ozone calculated in the same statistical form of the standards are referred to as metric values of the corresponding standard. The GDAD specifies the calculation procedures that are to be followed and the data completeness requirements that must be satisfied to calculate a valid metric value. An air zone achieves a given standard if the metric value is equal to or less than the standard (CCME, 2012a). The CAAQS metrics are calculated as follows:

The PM2.5 24-hour metric is the 3-year average of the annual 98th percentile of the daily 24-hour average concentrations.

The PM2.5 annual metric is the 3-year average of the annual average concentrations.

The ozone metric is the 3-year average of the 4th highest daily maximum 8-hour rolling average concentrations.

4.2 Transboundary Flow and Exceptional Events

In order to determine whether the CAAQS have been achieved and to assess the metrics against the CAAQS management levels, data affected by transboundary flow and exceptional events (TF/EE) are identified and removed from the CAAQS metric calculations. Transboundary flows are defined as the transport of air pollution across provincial and territorial boundaries, and between Canada and the United States. Exceptional events are events that contribute to air pollution levels in an air zone and satisfy at least one of the following criteria:

The event is not reasonably controllable or preventable;

The event is caused by human activities which are unlikely to reoccur; or

The event is a natural source; “natural” means an event in which human activities play little or no direct causal role to the event in question.

In order to identify TF/EE, the weight of evidence approach is used. This method is outlined in the GDAD (CCME, 2012a). A description of the weight of evidence approach is given in Appendix A.

5.0 TF/EE Influences on the Metric

After the analysis of transboundary flows and exceptional events (TF/EE), all stations in all air zones achieved CAAQS for PM2.5 and ozone for the assessment period 2012-2014 and the assessment period 2013-2015. For the 2011-2013 assessment period, the CAAQS were exceeded for PM2.5 in the Red Deer air zone. For the 2012-2014 and 2013-2015 assessment periods, the Red Deer air zone did not exceed the CAAQS. In Alberta the most common TF/EE influences are forest fire smoke events, which can affect both the PM2.5 and ozone metrics. Elevated ozone concentrations in the spring also constitute a common TF/EE influence which affects the ozone metric only. Appendix B highlights the CAAQS metric values by station and air zone prior to the removal of these TF/EE influences, while Appendix C provides a discussion of observations prior to the removal of TF/EE influences. Forest fire smoke was found to be the largest contributor to PM2.5 TF/EE events in both assessment periods. The data from such events that meet the TF/EE criteria (section 4.2) are removed from the CAAQS calculations prior to comparing metric values to standards and associated management levels. Elevated PM2.5 concentrations that are not considered to be affected by TF/EE are most often observed in the winter, when wind-speeds are low and frequent temperature inversions lead to conditions that are not conducive to dispersion. This allows for the accumulation of precursor gases, such as nitrogen oxides, sulphur dioxide and organic compounds, and can lead to the production of secondary particulate matter. The ozone metrics are primarily affected by elevated ozone concentrations observed in the spring-time. These events, observed annually and almost simultaneously throughout the province, most likely do not have significant contribution from local or regional anthropogenic activities. Some studies have attributed elevated spring time ozone to long range transport of precursors (Monks 2000, Cooper et al. 2010, Christensen et al. 2015). To a lesser degree elevated ozone is associated with transport of forest fire emissions and their associated secondary pollutants into the region. These events are identified as TF/EE and removed from the calculations. Ozone events that are not considered TF/EE are typically observed in the summer-time and are associated with photochemistry in the presence of nitrogen oxides and volatile organic compounds. Within an urban context, ozone was observed to be lowest within the most dense population centers, while the highest ozone levels were observed in areas immediately surrounding these urban cores. This “donut” around the urban centres occurs because higher levels of nitrogen oxides in the city temporarily sequester (reduce) ozone.

6.0 CAAQS Management Levels for 2012-2014 and 2013-2015

In this section, ozone and PM2.5 management levels are determined by comparing ozone and PM2.5 metrics to the CAAQS and associated thresholds. Ozone and PM2.5 metrics are compared against the CAAQS and associated management level thresholds after the removal of identified transboundary flow and exceptional events (TF/EE). The following steps were taken to determine the management level for the air zone:

Metric values are calculated for each station within an air zone for each pollutant.

TF/EE are identified and removed from the data.

Metric values are recalculated after TF/EE influenced events are removed. Before the removal of TF/EE, all air zones achieved the ozone CAAQS, however the Lower Athabasca air zone exceeded the PM2.5 24-hour CAAQS and the North Saskatchewan air zone exceeded the PM2.5 24-hour CAAQS and the PM2.5 annual CAAQS. After the removal of TF/EE all air zones achieved the CAAQS. Demonstration of the influence of TF/EE on CAAQS metrics is shown in Tables A1 to A9 in Appendix A. Management levels for each air zone are determined for both ozone and PM2.5. The management level for an air zone is determined by comparing the station with the highest metric value after TF/EE events are removed against the threshold values in the CAAQS management levels (see Section 2). Since there are two CAAQS averaging times for PM2.5, the air zone management level is first determined for both the PM2.5 24-hour and PM2.5 annual metrics. The final PM2.5 management level for the air zone is the more stringent of the two (e.g., if the 24-hour PM2.5 is orange and the annual PM2.5 is yellow, the PM2.5 management level for the air zone is orange). PM2.5 management levels for all air zones were unchanged between the 2012-2014 and 2013-2015 assessments (Figure 2). Assessment results show that all air zones, with the exception of the Peace air zone, were in the orange management level (actions for preventing CAAQS exceedances) for PM2.5 for the 2012-2014 and 2013-2015 assessment periods. The Peace air zone was in the yellow management level (actions for preventing air quality deterioration) for both time periods. Ozone management levels were also unchanged between the 2012-2014 and 2013-2015 assessments for all air zones (Figure 3). The ozone management level was orange for the North Saskatchewan region for both assessment periods. The Lower Athabasca, Upper Athabasca, Red Deer, and South Saskatchewan air zones were assigned to the yellow management level for both assessment periods. However, at the Red Deer Riverside station, the data for 2015 did not meet data quality objectives and were removed from the calculation. Therefore, the ozone management level for the Red Deer air zone in the 2013-2015 assessment was based on two years of valid data. It is possible that the same issue that resulted in invalidation of the 2015 data may have affected data in 2014 from the Riverside station. While there is insufficient evidence to invalidate the 2014 data, peak ozone concentrations, and consequently the CAAQS metric for the Red Deer air zone, may be biased low in 2014 compared with other reporting years and although we

present them here they should be treated with caution (see Appendix C.11 for details regarding the 2014 and 2015 ozone data at Red Deer Riverside). The Peace air zone was in the green management level (actions for keeping clean areas clean) for both assessment periods. Figure 2 and Figure 3 show air zone management levels for the 2011-2013, 2012-2014 and 2013-2015 assessment periods for PM2.5 and ozone, respectively. Table E1 and Table E2 in Appendix E show the management level assignments for each station in these air zones after TF/EE analysis for the 2012-2014 and 2013-2015 assessment periods, respectively.

7.0 Management Actions

Alberta Environment and Parks developed management plans to improve air quality in air zones assigned to the red and orange management levels for PM2.5 and ozone, as outlined in the 2011-2013 assessment report (AEP, 2015a). Alberta Environment and Parks will undertake actions in the following areas to reduce air emissions: regional planning actions, policy actions, regulatory process actions, knowledge improvement, and engagement actions. The following section highlights some of the management actions in each area. Management actions will vary from zone to zone based on the emission sources within each zone, and the management level to which the zone has been assigned. For a comprehensive list of the management actions to be undertaken in each zone, please refer to the individual management response reports for each air zone, available at the Alberta Environment and Parks air management frameworks website http://aep.alberta.ca/air/management-frameworks/canadian-ambient-air-quality-standards/management-plans.aspx.

Regional planning actions include continuing to advance the development of regional land-use plans and associated air quality management frameworks within each region, including the incorporation of CAAQS and the associated air zone management thresholds into the air quality management frameworks. The Capital Region Fine Particulate Matter Response (AEP, 2014), developed in response to the exceedance of Canada-Wide Standards for PM2.5 in the Capital Region for the 2008-2010, 2009-2011, and 2010-2012 assessments, and the Red Deer Fine Particulate Matter Response (AEP, 2016), developed in response to exceedance of Canada-Wide Standards for PM2.5 at Red Deer Riverside for the 2009-2011 assessment, will continue to be implemented. Policy actions are being assessed that can be applied in air zones at orange and red CAAQS management levels. This includes the assessment of technology and equipment standards and policies for point sources (e.g. large industry) and non-point sources (e.g. transportation). Emission control standards for industrial facilities in Alberta that are regulated by the Environmental Protection and Enhancement Act (EPEA) operate under terms and conditions indicated in approval documents. The management response reports include regulatory process actions to apply more stringent emission standards to industrial sources in zones at the red and orange levels in renewal applications. This may include a requirement that emission control technologies be on par with leading jurisdictions for major new emission sources. Knowledge improvement actions aim to advance knowledge in priority areas and inform management actions through work with local airshed organizations and other partners. These actions include, but are not limited to, assessing the adequacy of the existing ambient air quality monitoring in the air zone, analyzing available monitoring data to investigate the possible cause or influences on elevated concentrations of PM2.5 and ozone, and implementing additional ambient air monitoring. Finally, engagement actions include working with stakeholders to achieve a better understanding of regional priorities to pursue management initiatives. Outreach and education to inform the public and stakeholders on the state of air quality, how it impacts them, and what they can do to help, will also be undertaken.

Appendix A Demonstrating the Influence of TF/EE

The weight of evidence approach is outlined in the GDAD (CCME, 2012a). This section describes transboundary flow and exceptional event (TF/EE) influences that were removed in order to demonstrate achievement of the CAAQS. In Alberta, the most frequent TF/EE influencing ozone concentration is elevated ozone concentrations observed in the spring-time that most likely do not have significant contribution from local or regional anthropogenic activities. In order to identify these events, the odd oxygen concentration (O3 + NO2) in the early morning and late evening hours are compared to the daytime maximum. Locally-produced ozone events are expected to occur under sunlit conditions and to have ozone values that increase over the course of the day. In some cases, forest fires produce ozone precursors resulting in elevated ozone concentrations in an air mass that has undergone atmospheric processing prior to arriving at a monitoring site. Forest fire smoke is the largest contributor to PM2.5 TF/EE events in both assessment periods. These smoke-related TF/EE influences are identified using back trajectories provided by Environment and Climate Change Canada, maps of forest fire hot spots, air quality health advisories, and satellite maps of forest fire smoke. Occasionally other types of TF/EE influences are identified. For example, on two days in 2014 at the Woodcroft station, levels of PM2.5 were affected when roofing work was being conducted on the building housing the air monitoring station. Also, PM2.5 levels were affected on two days in 2013 at the Edmonton East station by a wind-blown dust event originating from activities that were deemed unlikely to reoccur. PM2.5 24-Hour Metric 2012-2014 Assessment Before the analysis for TF/EE, three stations exceeded the PM2.5 24-hour metric for the 2012-2014 assessment: Beaverlodge in the Peace air zone, CNRL Horizon in the Lower Athabasca air zone, and Edmonton East in the North Saskatchewan air zone. After removing TF/EE influences associated with forest fire smoke, all three stations achieved the CAAQS. Tables A1 through Table A3 list the dates and the 20 largest 24-hour average PM2.5 values for each year for the 2012-2014 assessment, ranked from highest to lowest at these stations. Note that additional TF/EE influences (not listed in this appendix) were removed at most stations prior to assessment of management levels.

PM2.5 24-Hour Metric 2013-2015 Assessment Before the analysis for TF/EE, five stations exceeded the PM2.5 24-hour metric for the 2013-2015 assessment: CNRL Horizon, Cold Lake South, Fort Chipewyan, Fort McMurray-Athabasca Valley and Fort McMurray-Patricia McInnes in the Lower Athabasca air zone. After removing TF/EE influences associated with forest fire smoke, all five stations achieved the CAAQS. For the 2013-2015 reporting period Table A5 through Table A9 list the dates and the 20 largest 24-hour average PM2.5 values for each year, ranked from highest to lowest at these stations. Note that additional TF/EE influences (not listed in this appendix) were removed at most stations prior to assessment of management levels. PM2.5 Annual Metric 2013-2015 Assessment All stations achieved the PM2.5 annual CAAQS for the 2013-2015 assessment period.

Appendix B CAAQS Metric values by Station and Air Zone Prior to the Removal of TF/EE Influences

The CAAQS metric values for each station in the six air zones are shown in Sections B.1, B.2 and B.3 for the PM2.5 24-hour, PM2.5 annual and ozone metric values, respectively. The air zone metric value is the maximum station metric value that meets data completeness criteria. Information on data completeness is included in the footnotes of Tables B1 to B6. TF/EE influences have not been removed from these metric values and therefore the values are not compared to CAAQS or the associated thresholds. B.1 PM2.5 24-hour Metric Values The PM2.5 24-hour metric values and the annual 98th percentiles for the 2012-2014 and 2013-2015 assessment periods are shown in Tables B1 and B2. These values are listed by air zone and ambient monitoring station without the removal of TF/EE. The metric values for the 2012-2014 period ranged from 21 µg m-3 in the South Saskatchewan air zone to 31 µg m-3 in the Lower Athabasca and North Saskatchewan air zones. For 2013-2015, the metric values ranged from 25 to 27 µg m-3 in all air zones except for Lower Athabasca where the metric value was 41 µg m-3. PM2.5 readings in the Lower Athabasca are frequently influenced by forest fire smoke.

B.2 PM2.5 Annual Metric Values The PM2.5 annual metric values and the annual averages for 2012-2014 and 2013-2015 prior to the removal of TF/EE are shown in Tables B3 and B4. Prior to the removal of TF/EE, the PM2.5 annual metric values ranged from 7.0 µg m-3 in the Peace air zone to 10.5 µg m-3 in the North Saskatchewan air zone based on 2012-2014 data. PM2.5 annual metric values ranged from 6.9 µg m-3 in the Peace air zone to 9.0 µg m-3 in the Upper Athabasca air zone based on 2013-2015 data. Forest fire smoke and human influences are likely the greatest contributor to elevated annual PM2.5 ambient concentrations.

Appendix C Discussion of TF/EE Influences by Station and Air Zone

Most stations, even those with metric values below the standards, were influenced by TF/EE. The following sections make note of any unusual events that may have influenced the metrics in the air zone for the applicable assessment periods and focus primarily on the events of 2014 and 2015, respectively. The values provided in the sections below are stated before removal of TF/EE events. Influences on the Metric by Air Zone (2012-2014 Assessment Period)

C.1. Peace Air Zone (2012-2014)

Before analysis of TF/EE, the Peace air zone achieved the CAAQS for PM2.5 and ozone. In 2014, all stations in the Peace air zone were largely impacted by forest fire smoke events. The Beaverlodge station recorded the highest PM2.5 concentrations with a 24-hour metric value of 29 µg m-3. The station did not meet data completeness criteria in 2013 and 2014. However, in 2014 the 98th percentile exceeded the standard, therefore in accordance with the GDAD, 2014 was included. Therefore, the 3-year average metric calculation for the PM2.5 24-hour metric is based on two years: 2012 and 2014. Because the Beaverlodge station did not meet the data completeness criteria of three years, the PM2.5 24-hour metric calculated for this station is not considered when assigning a management level to the air zone. Demonstration of TF/EE analysis for the PM2.5 24-hour metric at the Beaverlodge station can be found in Table A1 in Appendix A. The Grande Prairie (Henry Pirker) station, which achieved the data completeness criteria for all three years, observed the highest annual 98th percentile for 2014 with a value of 35.9 µg m-3

and had a PM2.5 24-hour metric value of 24 µg m-3. The highest 2012-2014 PM2.5 annual metric value for the air zone was 7.0 µg m-3 based on the Grande Prairie (Henry Pirker) station. The Beaverlodge station did not achieve the data completeness criteria and therefore was not considered for the annual PM2.5 metric. The Beaverlodge station had the highest ozone metric for 2012-2014 in the Peace air zone, at 56 ppb. Therefore, even before the consideration of TF/EE influences, levels of ozone were well below the standard.

C.2. Lower Athabasca Air Zone (2012-2014)

Before analysis of TF/EE, the Lower Athabasca air zone exceeded the PM2.5 24-hour CAAQS due to forest fire influences but achieved the CAAQS for annual PM2.5 and ozone. In 2012 and 2014, the PM2.5 98th percentile values were very high at most stations in the Lower Athabasca air zone due to wide-spread forest fire smoke events. The PM2.5 98th percentile in 2013 was generally much lower in this air zone due to a decreased influence from forest fire smoke.

The Fort Chipewyan station observed the highest PM2.5 98th percentile in 2014 with a value of 39.7 µg m-3. In 2014 all stations in the Lower Athabasca air zone were largely impacted by forest fire smoke from wildfires. The Cold Lake South station did not meet the data completeness criteria for PM2.5 in 2012 and therefore the 3-year average metric was based on two years. Because of this, the data from the Cold Lake South station was not considered in setting a management level for the air zone. The CNRL Horizon station observed the highest metric value of 31 µg m-3 for the 2012-2014 assessment period. Demonstration of TF/EE analysis for the PM2.5 24-hour metric at the CNRL Horizon station can be found in Table in Appendix A. The highest 2012-2014 PM2.5 annual metric was found at the CNRL Horizon station with a value of 9.1 µg m-3. After the removal of TF/EE influences, the Lower Athabasca air zone achieves CAAQS for PM2.5 for the 2012-2014 assessment. The ozone metric for 2012-2014 in the Lower Athabasca air zone was 58 ppb, based on data from the Cold Lake South station and lower than the standard even before the consideration of TF/EE influences. The highest concentrations of ozone in the Lower Athabasca air zone for the 2012-2014 assessment was observed in 2013 at the Cold Lake South station with a 4th highest daily maximum 8-hour average concentration of 65.1 ppb.

C.3. Upper Athabasca Air Zone (2012-2014)

Before analysis of TF/EE, the Upper Athabasca air zone achieved the CAAQS for PM2.5

and ozone. The Hinton station observed the highest concentrations of PM2.5 in the air zone with a 24-hour metric value of 24 µg m-3 and an annual metric value of 8.7 µg m-3. Elevated PM2.5

concentrations at this station were likely due to wind-blown dust from a nearby road and parking lot. A focused study is currently being conducted in Hinton to investigate this issue further (see Section 7). The highest ozone metric for 2012-2014 in the Upper Athabasca air zone of 61 ppb was found at the Steeper station. Even before the consideration of TF/EE influences, the ozone metric values in the Upper Athabasca air zone are below the standard. The Steeper station is a high elevation station situated at 1400 metres above sea level and located to the east of the Rocky Mountains. Ozone concentrations at the Steeper station are often the highest in the province likely due to greater availability of biogenic volatile organic compounds from forest cover in the area and vertical transport of ozone. The Hinton station did not measure ozone in the years 2012 and 2013. Because of this, the Hinton station was not considered in assigning the management action level for the air zone for the 2012-2014 assessment.

C.4. North Saskatchewan Air Zone (2012-2014)

Before the analysis of TF/EE, the North Saskatchewan air zone exceeded the PM2.5 24-hour and PM2.5 annual CAAQS but achieved the CAAQS for ozone. The Edmonton East station showed the highest PM2.5 metrics in the air zone for the 2012-2014 assessment with a 24-hour metric value of 31 µg m-3 and an annual metric value of 10.5 µg m-3. The Edmonton East station is located in an industrial area, however it is used for CAAQS reporting as it is close to a residential district and it is accessed by the public. After the removal of days impacted by TF/EE, the Edmonton East station achieves CAAQS with a metric value of 28 µg m-3 and 9.7 µg m-3, for the 24-hour metric and annual metric, respectively (Table A3 and Table A4 in Appendix A). The Edmonton-Woodcroft, St. Lina and Edmonton South stations did not meet the data completeness criteria for the 3-year time period and therefore could not be considered for assignment of the PM2.5 management action levels. The Edmonton-Woodcroft station only met the data completeness criteria in 2014 and the St. Lina station only met the data completeness criteria in 2012. The Edmonton South station met the data completeness criteria in 2013 and 2014. All three years need to meet the data completeness criteria in order for the station to be used in the assignment of the management action level. The ozone metric for 2012-2014 in the North Saskatchewan air zone was 61 ppb. Therefore, even before the consideration of TF/EE influences, levels of ozone are below the standard. The highest ozone levels in the North Saskatchewan air zone, based on a 3-year average of the annual 4th highest value, were measured at the Caroline station and the Tomahawk station. These two stations are in rural areas and therefore are not subject to the higher levels of nitrogen oxides as in cities that would temporarily sequester (reduce) ozone. Data for the Edmonton-Woodcroft station was not available for 2012 and did not meet the completeness criteria for ozone in 2013 and therefore the 3-year average could not be calculated for the ozone metric value. Because of this, this station was not considered for the air zone metric for ozone.

C.5. Red Deer Air Zone (2012-2014)

Before analysis of TF/EE, the Red Deer air zone achieved the CAAQS for PM2.5 and ozone. The Red Deer air zone exceeded the CAAQS for the PM2.5 24-hour and PM2.5 annual metrics in 2011-2013, but achieved the CAAQS for both metrics in 2012-2014. There are several possible sources of PM2.5 and PM2.5 precursors in the area, including emissions from transportation and home heating, as well as large industrial facilities. A focused air quality monitoring study has been initiated to further understand the sources of PM2.5 in Red Deer (see Section 7).

April 2018 Alberta: Air Zones Report 2012-2014, 2013-2015 Page 39 of 48 © 2018 Government of Alberta

The ozone metric for 2012-2014 in the Red Deer air zone was 55 ppb. Therefore, even before the consideration of TF/EE influences, levels of ozone are below the standard. During an audit of the Red Deer Riverside station on October 11, 2016, a manifold inlet blockage was discovered. This was followed by a detailed data quality assessment for the station. Comparison of the ozone data from the Red Deer Riverside station with data from the Lancaster station showed a marked divergence between the two stations, with the Riverside station measuring lower peak ozone concentrations than the Lancaster station starting in early 2015 and persisting until the time of the October 2016 audit. A similar comparison between the two stations could not be carried out for 2014 as the Lancaster station was only in operation for three months in 2014. Therefore, there was not enough evidence to remove the Riverside data from the CAAQS reporting for 2014. However, the Riverside ozone data in 2014 exhibited similar characteristics to the data in 2015. Therefore, peak ozone concentrations, and consequently the CAAQS metric, may be biased low in 2014 compared with other reporting years.

C.6. South Saskatchewan Air Zone (2012-2014)

Before analysis of TF/EE, the South Saskatchewan air zone achieved the CAAQS for PM2.5 and ozone. The Calgary Central station and the Lethbridge station did not meet the PM2.5 completeness criteria in 2012 and the Medicine Hat-Crescent Heights station did not meet the PM2.5 completeness criteria in 2013. The Calgary Southeast station was not in operation in 2012 and 2013 and did not meet PM2.5 completeness criteria in 2014. For these reasons, these four stations were not considered for the air zone PM2.5 metric. The highest annual 98th percentile value in the South Saskatchewan air zone was at the Calgary Northwest station in 2013 with a value of 22.9 µg m-3. The air zone metric value for the 2012-2014 assessment period was 21 µg m-3 based on the Calgary Northwest station. This was primarily associated with wintertime conditions conducive to the accumulation of precursors. In 2014, the Calgary Northwest station was also affected with the TF/EE influence of forest fire smoke. The ozone metric for 2012-2014 in the South Saskatchewan air zone was 61 ppb and below the CAAQS even before the consideration of TF/EE influences. The highest ozone metric in the South Saskatchewan air zone was from the Calgary Northwest station.

Influences on the Metric by Air Zone (2013-2015 Assessment Period)

C.7. Peace Air Zone (2013-2015)

Before analysis of TF/EE, the Peace air zone achieved the CAAQS for PM2.5 and ozone. The Grande Prairie (Henry Pirker) station observed the highest PM2.5 concentrations in 2015, with a 98th percentile value of 20.6 µg m-3 and an annual average of 6.3 µg m-3. The Beaverlodge station did not meet the data completeness criteria for PM2.5 in 2013 and 2014. With only one year available for the 2013-2015 assessment, the PM2.5 metric calculated for this station is not considered when assigning a management level to the air zone. The highest ozone metric for 2013-2015 in the Peace air zone, from the Beaverlodge station, was 58 ppb. Therefore, even before the consideration of TF/EE influences, levels of ozone are well below the standard.

C.8. Lower Athabasca Air Zone (2013-2015)

Before analysis of TF/EE, the Lower Athabasca air zone exceeded the CAAQS for 24-hour PM2.5 but achieved the CAAQS for annual PM2.5 and ozone. The air zone was largely impacted by forest fire smoke in 2015. In the 2013-2015 assessment, five stations exceeded the PM2.5 24-hour metric: Cold Lake South, CNRL Horizon, Fort Chipewyan, Fort McMurray-Athabasca Valley and Fort McMurray-Patricia McInnes. The highest 24-hour PM2.5 metric in the Lower Athabasca air zone was detected at the Fort Chipewyan station with a metric value of 41 µg m-3 and a 98th percentile value for 2015 of 69.4 µg m-3. The highest 24-hour average PM2.5 concentration at this station was 397 µg m-3 on June 29, 2015. Forest fires were evident throughout northern Alberta in 2015, with air quality advisories issued by Alberta Health Services in May, June and July. The highest PM2.5 annual metric was detected at CNRL Horizon with a metric value of 8.8 µg m-3. Demonstration of TF/EE analysis at these stations can be found in Tables A5 to A9 in Appendix A. The ozone metric for 2013-2015 in the Lower Athabasca air zone was unchanged from the 2012-2014 ozone metric at 58 ppb, and lower than the CAAQS even before the consideration of TF/EE influences. The highest ozone metric in the Lower Athabasca air zone for the 2013-2015 assessment was observed at the Fort McKay–Bertha Ganter and Cold Lake South stations, both with a metric value of 58 ppb.

C.9. Upper Athabasca Air Zone (2013-2015)

Before analysis of TF/EE, the Upper Athabasca air zone achieved the CAAQS for PM2.5 and ozone.

April 2018 Alberta: Air Zones Report 2012-2014, 2013-2015 Page 41 of 48 © 2018 Government of Alberta

The Hinton station observed the highest concentrations of PM2.5 in the air zone in the 2013-2015 assessment with a 24-hour metric value of 25 µg m-3 and an annual metric value of 9.0 µg m-3. Wind-blown dust from a nearby road and parking lot are likely the source of elevated PM2.5 concentrations at this station. Focused air monitoring is being conducted for the Hinton area to determine whether these dust events are localized around the current station or are reflective of air quality throughout Hinton (see Section 7). The highest ozone metric value for 2013-2015 in the Upper Athabasca air zone was 63 ppb and was measured at the Hinton station. However, ozone data for this station was only available for two years (2014 and 2015) and therefore the metric value could not be considered for the air zone metric. The next highest ozone metric value for 2013-2015 in the Upper Athabasca air zone was 61 ppb and was calculated from data at the Carrot Creek station. Even before the consideration of TF/EE influences, the ozone metric values in the Upper Athabasca air zone are below the CAAQS.

C.10. North Saskatchewan Air Zone (2013-2015)

Before analysis of TF/EE, the North Saskatchewan air zone achieved the CAAQS for PM2.5 and ozone. The Edmonton East station had the highest PM2.5 24-hour metric value of 35 µg m-3 for the 2013-2015 assessment period. However, the data completeness requirement was not met for 2015 at this station and therefore the metric value is based on two years of data. The Edmonton-Woodcroft station also did not meet the data completeness criteria for PM2.5 in 2013 and therefore the metric is based on two years of data. The St. Lina station did not meet the data completeness criteria for PM2.5 in 2013 and 2014 and therefore the 3-year average could not be calculated for the PM2.5 metric value. As a result, these three stations were not considered for the assignment of a PM2.5 management action level for the air zone. The Bruderheim, Fort Saskatchewan and Lamont County stations showed the highest PM2.5 24-hour metrics in the air zone with metric values of 26 µg m-3. The Edmonton East station and the Edmonton-Woodcroft station both exceeded the PM2.5 annual standard with metric values of 11.1 µg m-3 and 10.1 µg m-3, respectively. Since this is based on two years, these values are not considered for determining an air zone management level. The highest PM2.5 annual metric was determined to be from the Edmonton South station with a value of 8.6 µg m-3, which is below the CAAQS even before the consideration of TF/EE influences. The highest ozone metric for 2013-2015 in the North Saskatchewan air zone was 68 ppb, at the Edmonton-Woodcroft station. The Edmonton-Woodcroft station did not meet the data completeness criteria in 2013 and therefore the metric was based on two years and not considered for the air zone metric. The ozone metric for 2013-2015 in the North Saskatchewan air zone, before the consideration of TF/EE influences, was 63 ppb at the Bruderheim station and did not exceed the standard.

C.11. Red Deer Air Zone (2013-2015)

Before analysis of TF/EE, the Red Deer air zone achieved the CAAQS for PM2.5 and ozone. The CAAQS monitoring station Lancaster was added in 2015, and had the highest PM2.5 98th percentile value in the air zone for that year at 25.9 µg m-3. However, with only one year of data, the station cannot be considered for the air zone metric. The Red Deer air zone 24-hour PM2.5 metric of 26 µg m-3 and the annual PM2.5 metric of 8.2 µg m-3 were based on the Red Deer Riverside station. During an audit of the Red Deer Riverside station on October 11, 2016, a manifold inlet blockage was discovered. This was followed by a detailed data quality assessment for the station. Comparison of the ozone data from the Red Deer Riverside station with data from the Lancaster station showed a marked divergence between the two stations, with the Riverside station measuring lower peak ozone concentrations than the Lancaster station starting in early 2015 and persisting until the time of the October 2016 audit. As such, data from 2015 is not included in the assessment. A similar comparison between the two stations could not be carried out for 2014 as the Lancaster station was only in operation for three months in 2014. Therefore, there was not enough evidence to remove the Riverside data from the CAAQS reporting for 2014 and the 3-year average ozone metric for the 2013-2015 assessment period is based on two years of data. However, the Riverside ozone data in 2014 exhibited similar characteristics to the data in 2015. Therefore, peak ozone concentrations, and consequently the CAAQS metric, may be biased low in 2014 compared with other reporting years.

C.12. South Saskatchewan Air Zone (2013-2015)

Before the analysis of TF/EE, the South Saskatchewan air zone achieved the CAAQS for PM2.5 and ozone. The South Saskatchewan air zone was largely impacted by the TF/EE influence of forest fire smoke in August 2015 from wildfires in British Columbia and the Northwest United States. Forest fire smoke from Saskatchewan and the north also influenced air quality in May, June, and July 2015. In April of 2015 the Calgary Central station was relocated to Calgary Central Inglewood, causing the data completeness criteria to not be met at both stations. The Calgary Southeast station was installed in 2015 and has collected only one year of data. Because of this, these stations are not considered for the air zone metric. The highest PM2.5 concentration in the South Saskatchewan air zone for 2015 was at the Medicine Hat-Crescent Heights station with a 98th percentile value of 45.5 µg m-3. The 2013-2015 24-hour metric value was 31 µg m-3. However, the station did not meet data completeness requirements in 2013 and therefore is not considered for the air zone metric. The Lethbridge station had the next highest concentration in 2015 with a 98th

percentile value of 42.0 µg m-3 and a 2013-2015 24-hour metric value of 27 µg m-3. The PM2.5 annual metric value of 8.3 µg m-3 was from the Calgary Northwest station. The ozone metric for 2013-2015 in the South Saskatchewan air zone was 63 ppb and did not exceed the CAAQS even before the consideration of TF/EE influences. The highest ozone metric value in the South Saskatchewan air zone was from the Calgary Northwest station.

Appendix E Management Level Assignments at Each Station

Table E1 and Table E2 detail the management level assignments for each station for both PM2.5 and ozone after TF/EE analysis for the 2012-2014 and 2013-2015 assessment periods, respectively. TF/EE analysis for the 2012-2014 assessment period was completed for all stations in the red, orange, and yellow management levels. TF/EE analysis for the 2013-2015 assessment period was completed for all stations in the red and orange management levels. Management planning must be implemented if the red or orange level has been assigned to an air zone. The 2013-2015 assessment identifies stations in the yellow management level as “Yellow or lower” if TF/EE analysis may have brought the station to the green management level.
