Message from the Executive Director

2012 has once again been a very exciting and busy year for the Association.

Plans were made to implement two continuous air quality monitoring stations in 2009. The

plan was to locate one air monitoring station in the Weyburn area and one in the southeastern

part of the region. SESAA has since installed these two continuous air monitoring stations and

plans to aggressively install additional air monitoring stations in the very near future. These

stations plus the passive monitoring network will provide high quality data and information

regarding regional air quality. The continuous data is available live on the internet; it includes

hourly concentrations of SO2, H2S, NO/NO2/NOx, PM2.5 and O3. The data was made available in

early 2011 on the SESAA website: http://www.sesaa.ca/AirQuality/index.php.

In the fall of 2011, the Association ordered a new airpointer® for March 2012 delivery. SESAA’s

Science Committee selected a site for the next airpointer®. It was purchased and placed in the

southeast part of the region near Glen Ewen. It has been operating since April 20, 2012. The

Science Committee developed its 5 year plan for the deployment of more continuous air

monitoring equipment. The SESAA Board will continue to look at ways of providing more and

better value and service to its members.

In the fall of 2011 the Board of Directors decided to make public presentations and events that

showcase SESAA and the members of SESAA a priority. To that end the Executive Director and

the Communications and Membership Committee hosted a Clean Air Day Workshop on June 6,

2012 in Estevan at the Saskatchewan Energy Training Institute. The Saskatchewan Ministry of

Environment, the Ministry of the Economy, the Canadian Association of Petroleum Producers

(CAPP) and others presented on topics regarding air quality. It was a successful workshop. The

presentations are all posted on the SESAA website. The Estevan Mercury Newspaper and CJ

1280 Radio covered the Workshop and highlighted SESAA and the work we do.

On June 6, 2012 SESAA held its Annual General Meeting at the Saskatchewan Energy Training

Institute in Estevan immediately following the Clean Air Day Workshop.

The Governance Committee reviewed the SESAA bylaws and made revisions. They were

approved at the 2012 Annual General Meeting.

The Science Committee worked on a 5 year review of the SESAA passive data. There were

recommendations from the review for a different data collection protocol which was

implemented in 2012. The 5 year report is on the SESAA website.

SESAA had enjoyed very good Board of Director development in 2010 with the addition of some

key Directors. In 2012, we were actively seeking an even broader representation by soliciting

for new Board members in local newspapers and by asking specific organizations for their

6

involvement. This has resulted in three new Board members: one from the City of Estevan and

two members of the public; one from Weyburn and one from Estevan. Please see the complete

list of the Board in Appendix F.

A great deal of effort has gone into securing sustainable funding and developing a fair and

equitable funding formula. 2012 saw a substantial improvement in the financial picture of the

Association as a result of additional memberships. The Saskatchewan Ministry of Environment

and the Saskatchewan Ministry of the Economy have made considerable steps to ensure

funding sustainability for the Airshed. SESAA thanks SaskPower, Saskatchewan Ministries of

Environment, the Economy and Health and all of our members for their support.

SESAA is proud to mention that we served on the Committee to help write the Industrial “Air”

Source Chapter of the new Saskatchewan Environmental Code. We have forged many new

relationships while working in this capacity.

Future plans include the placement of the next continuous air monitoring stations,

development of more communication materials, presentations to municipalities, Chambers of

Commerce, high school classes, home and school meetings, etc.

Our goal is to collect credible and defensible air quality data and provide excellent service to

our members.

Executive Summary

The Southeast Saskatchewan Airshed Association (SESAA), established in October 2005, is

Saskatchewan’s first airshed association with a mandate to monitor ambient air quality in the

southeast region of the Province. SESAA is a collaborative group of industry, government, non-

government organizations, and private citizens. The airshed covers an area of 36,800 square

kilometres and includes 45 municipalities. Major economic activities in the region include

agriculture, oil & gas, mining, power generation, and transportation.

The SESAA ambient air quality monitoring network consists of two airpointers® at the Weyburn

and Glen Ewen stations, as well as a passive monitoring network. Both airpointers® measure

real-time data for SO2, H2S, NO/NO2/NOx, O3, ambient temperature, relative humidity,

accumulated precipitation, and wind speed/wind direction. The Weyburn airpointer® also

measures fine particulate matter (PM2.5). Real-time monitoring data of the airpointers® is

available on the SESAA website, which marks an important milestone in the SESAA’s

development. The passive network operated 30 stations until August 2013; it was then reduced

to 19 stations. The network measures 30-day average SO2, NO2, O3, and H2S. Passive NH3 and

BTEX (benzene, toluene, ethylbenzene, and xylene) were added after August.

The airpointers® were greater than 90% operational for the year of 2012, with the exception of

the Weyburn NOx analyzer for the months of June and July. Since June, the analyzer could not

measure ambient concentration correctly after the daily Automatic Instrument Check. The

affected data was tagged with a flag indicating it was invalid. The analyzer was taken offline for

factory repair on July 14 and resumed service on July 25.

The air quality at both airpointer® stations was within the Saskatchewan Ambient Air Quality

Standards (SAAQS), with the exception of hydrogen sulphide (H2S). According to the Air Quality

Index and Air Quality Health Index, the air quality was rated Good and Low Risk for more than

95% of the time at both stations. The Weyburn station detected 111 exceedance events for 1-

hour average H2S and 28 exceedance events for 24-hour average H2S. The exceedances were

associated with winds from the E-to-S (east to south) directions. It has yet to be determined if

the cause of H2S emissions are associated with localized industrial or natural sources. The Glen

Ewen station detected 8 exceedance events for 1-hour average H2S. As the number of

exceedance events was low, a source-receptor relationship has not yet been determined.

For the passive network, the sample capture rate was greater than 99% for all parameters. The

measured concentrations were low in comparison with the SAAQS. The maximum

concentrations for SO2, NO2, O3, H2S, and NH3 were 3.2 ppb, 10.2 ppb, 36 ppb, 1.8 ppb, and 1.9

ppb, respectively. The passive SO2 concentrations seemed to exhibit a spatial trend: higher

concentrations were detected in the central and southern part of the airshed zone, where more

industrial activities exist. There was no apparent spatial trend for passive NO2 and O3. The

measured benzene and toluene concentrations were less than 1 ppb. All ethylbenzene and

xylene samples were less than the method detection limit of 0.2 ppb.

1.0 Introduction

The Southeast Saskatchewan Airshed Association (SESAA) was established in October 2005 to

manage ambient air quality in southeast Saskatchewan. The SESAA is a consortium of

government, industry, non-government organizations, and private citizen stakeholders. The

goal of the association is to collect credible, scientifically defensible air quality data for the

southeast region of Saskatchewan, and to make this data freely available to all stakeholders.

The SESAA objective is to bring together stakeholders from all backgrounds to identify local air

quality issues and to develop innovative solutions for managing these issues.

The Southeast Saskatchewan airshed is Saskatchewan’s first airshed. It covers an area of 36,800

square kilometres, including 45 municipalities. The airshed boundaries were established based

on common history, meteorology, and funding considerations. Major economic activities in the

region include agriculture, oil and gas, mining, power generation, and transportation.

Membership in the SESAA is currently voluntary. The current membership includes members of

the agriculture, oil & gas, mining and power generation sectors, as well as the public. The

Government of Saskatchewan Ministries of Environment, Energy & Resources, and Health, as

well as representatives of the City of Estevan and Rural Municipality of Enniskillen Number 3

also participate as members of the Board of Directors. SESAA’s operating budget consists of

membership fees, environmental footprint, and emissions-based fees assessed to facilities

operating within the airshed zone (Figure 1).

2.0 Air Quality Monitoring

2.1 Continuous Air Quality Monitoring

2.1.1 airpointer®

The Southeast Saskatchewan airshed operates two airpointers® at the Weyburn station and

Glen Ewen station. The Weyburn station is situated approximately 12 kilometres south of the

City of Weyburn, just east of highway 35. This station has been in place and operating since

March 2010. The Glen Ewen station started operations in May 2012. This station is situated

approximately 2 km southeast of the Village of Glen Ewen, and approximately 0.5 km south of

highway 18. Real-time air monitoring data is available on the SESAA website at: www.sesaa.ca.

The airpointer® introduces a new concept in air quality monitoring. In the past, a multi-gas and

particle pollution monitoring system would have been housed in a large walk-in shelter;

sometimes in a trailer-type unit. The airpointer® makes it possible to acquire real-time data in a

small vault type, self-contained unit. The airpointer® has very low operating costs compared to

other analyzers in the industry. This is important to our members because we can provide

quality data collection at a considerable saving. Furthermore, it is easy to access the monitoring

data. A standard internet connection and web browser is all that is required.

The airpointer® measures a wide variety of pollutants. Both SESAA airpointer® stations measure

SO2, H2S, NO/NO2/NOX, O3, and meteorological parameters including ambient temperature,

relative humidity, precipitation, wind speed and wind direction. The Weyburn airpointer® also

monitors fine particulate matter (PM2.5). These parameters can be used to calculate hourly Air

Quality Index (AQI) and Air Quality Health Index (AQHI).

Table 1 summarizes the annual statistics for 1-hour average measurements for the SESAA air

monitoring network. The annual uptime was greater than 90% for all analyzers. The measured

concentrations were lower than the applicable Saskatchewan Ambient Air Quality Standards

(SAAQS, Appendix A), with the exceptions for H2S. Please refer to the following Sections for

detailed monitoring results.

2.1.2 Wind

Wind plays an important role in the transportation and dilution of air pollutants. Wind speed

and wind direction are main factors that influence regional air quality. The diffusion and

dispersion of emissions are greatly impacted by variations in wind speed and corresponding air

turbulence.

Figure 2 presents the wind roses for the Weyburn and Glen Ewen stations. At the Weyburn

station, prevailing wind was from the E-to-SE (east to southeast) and WSW-to-WNW (west-

northwest to west-southwest) directions. According to the international wind classification

chart, the wind consisted of 19% Light Air (<1.4 m/s), 35% Light Breeze (<3.1 m/s), and 40%

Moderate Breeze (<7.8 m/s). Stronger winds (>7.8 m/s) were primarily from the prevailing wind

directions.

At the Glen Ewen station, prevailing wind was from the E-to-SE (east to southeast) and W-to-

NNW (west to north-northwest) directions. The wind consisted of 20% Light Air, 37% Light

Breeze, and 39% Moderate Breeze. Stronger winds (>7.8 m/s) were primarily from the

prevailing wind directions.

The detail frequency distribution tables are presented in Appendix B: Table B-12 and Appendix C:

2.1.3 Sulphur Dioxide

Sulphur dioxide (SO2) is a colourless gas with a strong suffocating odour. It smells like burnt

matches. At concentrations above 300 ppb, it can be detected by taste and odour. The health

effects caused by exposure to high levels of SO2 include breathing problems, respiratory illness,

changes in lung function, and worsening respiratory and cardiovascular disease. People with

asthma or chronic lung or heart disease are the most susceptible to SO2. SO2 also damages

trees and crops.

SO2, along with nitrogen oxides, are the main precursors of photochemical smog and acid rain,

which contributes to the acidification of lakes and streams, accelerated corrosion of buildings,

and reduced visibility. SO2 in the air can form microscopic acid aerosols, which have serious

health implications, as well as, contributing to climate change.

Anthropogenic SO2 emission sources are primarily from combustion of sulphur containing fuels

(e.g. gasoline, natural gas and coal) and processing of sulphur containing ores. The major

emission sources for SO2 include large industrial sources such as power plants, petroleum

refineries, iron and steel mills, fertilizer plants, pulp and paper mills, and smelters, as well as

small industries, such as small oil and gas plants, battery and well flares.

The Saskatchewan Ambient Air Quality Standards (SAAQS) for sulphur dioxide are:

• 0.17 ppm (172 ppb) averaged over a 1-hour period;

• 0.06 ppm (57 ppb) averaged over a 24-hour period; and

• 0.01 ppm (11 ppb) as an annual arithmetic average.

Table 2 summarizes the monthly statistics for SO2 monitoring data. The instrument uptime was

greater than 90% throughout this year. The annual average uptime was 99.9% and 98.7% at

the Weyburn and Glen Ewen stations, respectively.

The measured concentration was quite low at both stations, in comparison with the SAAQS.

There was no exceedance of 1-hour or 24-hour SAAQS in 2012. The annual average

concentration of 2 ppb was lower than the annual SAAQS. The monthly average concentrations

ranged from 2 ppb to 4 ppb. There was no significant monthly or seasonal trend. The maximum

1-hour concentrations were 38 ppb and 35 ppb at the Weyburn and Glen Ewen stations

respectively. The maximum 24-hour concentrations were 10 ppb and 6 ppb, respectively.

Figure 3 presents the pollutant roses for 1-hour average concentration of SO2. At the Weyburn

station, the high concentration petals (>10 ppb) generally indicate that sources are located in

the E-to-S (east to south) directions, where more industrial activities exist, such as coal-fired

power plants and upstream oil and gas industry. At the Glen Ewen station, the high

concentration petals (>10 ppb) generally indicate that sources are located in the W-to-NW

15

(west to northwest) directions, where more industrial activities exist, such as upstream oil and

gas industry.

The detailed frequency distribution table for the pollutant rose is presented in Appendix B:

2.1.4 Nitrogen Dioxide

Nitrogen oxides, also known as oxides of nitrogen (NOX), is a collective term for nitric oxide

(NO) and nitrogen dioxide (NO2). Nitric oxide is a colorless, flammable gas with a slight odour.

Nitrogen dioxide is a reddish brown, non-flammable gas with a pungent irritating odour. NO2 is

of more interest than NO from both a health and acid rain perspective.

NOX can cause respiratory disease, damage vegetation, and reduce visibility. The primary

concern with NOX emissions is their contribution to formation of ground-level ozone, smog and

acid rain. To a lesser extent, some NOX compounds (e.g. N2O) contribute to stratospheric ozone

layer depletion and global warming.

NOX emissions are mainly produced by fossil fuel combustion. High temperature conditions

during combustion result in the formation of NOX as a by-product. The major anthropogenic

emission sources for NOX are associated with fuel combustion, including both stationary

sources, such as power plants, oil and gas industries, incinerators, as well as mobile sources

such as automobiles. Non-combustion sources, for example nitric acid manufacture, welding

processes and the use of explosives, comprise the smaller emission sources. In large cities,

motor vehicle emission is the major source of NOX.

The Saskatchewan Ministry of Environment regulates ambient air concentration for nitrogen

dioxide. The Saskatchewan Ambient Air Quality Standards for nitrogen dioxide are:

• 0.2 ppm (212 ppb) averaged over a 1-hour period; and

• 0.05 ppm (53 ppb) as an annual arithmetic average.

Table 3 summarizes the monthly statistics for continuous NO2 monitoring data. The instrument

was greater than 90% operational at both stations with the exception of June and July at the

Weyburn station. In June and July, the NOx analyzer was experiencing a slow recovery time,

taking longer than usual to correctly measure ambient air concentration following the daily

Automatic Instrument Check (AIC). As such, the affected data was tagged with a flag indicating

the data was invalid. The analyzer was taken offline for factory repair on July 14 and resumed

service on July 25.

The measured NO2 concentration was low in comparison with the SAAQS. There was no

exceedance of the 1-hour SAAQS in 2012. The annual average concentrations were 2.5 ppb and

2.7 ppb at the Weyburn and Glen Ewen stations. The monthly average concentrations ranged

from 1.7 ppb to 4.1 ppb. There was no significant monthly or seasonal trend. The maximum 1-

hour average concentrations were 15.9 ppb and 23.9 ppb at the Weyburn and Glen Ewen

stations. The maximum 24-hour average concentrations were 8.8 ppb and 8.9 ppb, respectively.

Figure 4 presents the pollutant roses for 1-hour average NO2. The measured concentration was

low; approximately 91% of the data was less than 5 ppb (the blue color petals). The remaining

18

9% of data fell between 5 ppb and 15 ppb. At the Weyburn station, the higher concentration

data tended to be associated with the E-to-SE (east to southeast) directions. At the Glen Ewen

station, the higher concentration data tended to be associated with the W-to-NNW (north to

north-northwest) directions. The direction trends were aligned with the area where more

industrial activities exist such as upstream oil and gas industry and/or coal-fired power plants.

The detailed frequency distribution table for the NO2 pollutant roses are presented in Appendix

B: Table B-4, and Appendix C: Table C-4. The tables for NO and NOx are in Tables B-3, B-5, and

Tables C-3, C-5.

2.1.5 Ozone

Ozone (O3) is a pale blue gas, slightly soluble in water. Most people can detect a sharp odour

resembling chlorine bleach at about 10 ppb concentration. Ozone can be formed by electrical

discharges and high energy electromagnetic radiation. In the indoor environments, ozone can

be present as a result of electronic equipment such as ionic air purifiers, laser printers,

photocopiers, and arc welders.

In the ambient air, O3 is a “secondary” pollutant, meaning it is not directly emitted from a

source. Instead, ozone is produced from photochemical reactions between oxides of nitrogen

(NOX) and volatile organic compounds (VOC) in the presence of sunlight. Some research

suggests that ground-level ozone could be from intrusion of ozone from the stratosphere,

mixing from the upper troposphere, local photochemistry and the medium and long-range

transport. There are split opinions regarding relative importance of these mechanisms. A study

in Regina suggested that high ozone events could be due to downward transport from the

stratosphere for the reviewed data.

Exposure to ozone has been linked to premature mortality and a range of morbidity health end-

points, such as hospital admissions and asthma symptoms. Acute exposure to high

concentrations of ozone can cause eye irritation and breathing difficulty. Ozone can

significantly impact vegetation and decrease the productivity of some crops. It damages cotton,

acetate, nylon, polyester and other textile materials. Ozone can also damage other synthetic

materials, cause cracks in rubber, accelerate fading of dyes, and speed deterioration of some

paints and coatings.

The Saskatchewan ambient air quality standard for ozone is:

• 0.08 ppm (82 ppb) averaged over a 1-hour period;

The Canada-Wide Standard (CWS) for ozone is:

• 65 ppb averaged over an 8-hour period (the achievement statistics is based on the

fourth highest measurement annually averaged over three consecutive years).

Table 4 summarizes the monthly statistics for O3 monitoring data. The instrument uptime was

greater than 90% throughout this year. The annual average uptime was 99.9% and 99.0% at

the Weyburn and Glen Ewen stations, respectively.

There was no exceedance of the SAAQS for 1-hour averages at both stations. The monthly

average concentrations ranged from 26 ppb to 35 ppb. The data seemed to exhibit a seasonal

trend, with high O3 concentration occurring in the spring and summer. The maximum 1-hour

average concentration of 68 ppb (Weyburn) and 71 ppb (Glen Ewen) were detected in

August/September. The 4th

highest concentration of 8-hour running average was 62 ppb at

21

both stations, which is less than the CWS standard (note: exceedance evaluation for the CWS

standard is based on the average of three consecutive years).

Figure 5 presents the pollutant roses for 1-hour average concentration of O3. The pollutant

roses did not show a directional trend for high concentration events. The detailed frequency

distribution table for the pollutant roses are presented in Appendix B: Table B-6, and Appendix C:

Table C-6.

2.1.6 Hydrogen Sulphide

Hydrogen sulphide (H2S) is a colourless gas with a characteristic “rotten egg” odour. It is

produced both naturally and through anthropogenic emission sources. H2S occurs naturally in

coal, crude oil, natural gas, oil, sulphur hot springs, volcanic gases, sloughs, swamps and lakes.

The major anthropogenic emission sources include natural gas and petroleum production,

wastewater treatment, pulp and paper mills, rayon textile manufacturing, and tar and asphalt

manufacturing. Decomposition of organic matter by bacteria under anaerobic conditions

releases H2S as well, forming the characteristic odour commonly associated with sewers,

sewage lagoons, and swamps.

Hydrogen sulphide is an acutely toxic gas at high levels. Exposure to hydrogen sulphide can

irritate the eyes, nose, throat, and lungs and can cause serious health effects, including death.

The Saskatchewan Ambient Air Quality Standards for hydrogen sulphide are:

• 10.8 ppb averaged over a 1-hour period; and

• 3.6 ppb averaged over a 24-hour period;

Table 5 summarizes the monthly statistics for continuous H2S monitoring data. The instrument

uptime was greater than 90% throughout this year at both stations.

The measured H2S concentration at both stations was lower than the SAAQS for the majority of

the time. However, there were occasional spikes causing exceedances of the 1-hour and 24-

hour SAAQS. At the Weyburn station, there were a total of 111 hours (or 1.3% of the total

monitoring hours) and 28 days when average H2S concentrations exceeded the SAAQS. The

maximum 1-hour and 24-hour average concentrations were 92.3 ppb and 8.5 ppb, respectively.

A complete list of the exceedance events can be found in Appendix D.

There were eight exceedance events for 1-hour average H2S at the Glen Ewen station, while all

the 24-hour averages were within the SAAQS. The maximum 1-hour and 24-hour average

concentrations were 33.9 ppb and 2.9 ppb, respectively. A complete list of the exceedance

events can be found in Appendix E.

Figure 6 presents the pollutant roses for 1-hour average concentration of H2S. At both stations,

H2S concentration was less than 3.6 ppb the majority of the time. The red petals represent the

concentration data exceeding the 1-hour SAAQS. At the Weyburn station, the exceedances

were primarily (93% of the exceedance events) associated with the E-to-S (east to south)

directions. The projected area is where more industrial activities exist, such as upstream oil and

gas industry. Eighty-six percent (86%) of the exceedance events were detected during light

wind conditions (<1.4 m/s). It has yet to be determined if the cause of H2S emissions are related

24

to localized industrial or biogenic sources. Further investigation is warranted by SESAA’s Science

Committee.

At the Glen Ewen station, the red petals are not visible due to a small number of the

exceedance events. The exceedance events were associated with a number of wind directions.

It has yet been determined if a spatial trend was existent with the high concentration events.

The detailed frequency distribution table for the pollutant roses are presented in Appendix B:

2.1.7 Fine Particulate Matter (PM2.5)

Particulate matter is unique among air pollutants, as it is identified by its size rather than by its

composition. The major concern for particulate matter deals with small particles referred to as

inhalable particulate, or PM10. PM10 is defined as particles that have an aerodynamic diameter

less than 10 microns (or 0.01 mm). PM10 can be divided into two groups of particles based on

size: fine particles and coarse particles. The fine particles are those particles with an

aerodynamic diameter smaller than 2.5 microns (0.0025 mm) and are identified as PM2.5. In

contrast, coarse particles are those with aerodynamic diameter greater than 2.5 microns and

less than 10 microns.

Fine particles are generally emitted from activities such as industrial and residential

combustion, and from vehicle exhaust. Fine particles are also formed in the atmosphere when

gases such as sulphur dioxide, nitrogen oxides, and volatile organic compounds, emitted by

combustion activities, are transformed by chemical reactions in the air.

Adverse health effects from breathing air with a high PM2.5 concentration include: premature

death, increased respiratory symptoms and disease, chronic bronchitis, and decreased lung

function particularly for individuals with asthma. Particulate matter can clog stomatal openings

of plants and interfere with photosynthesis functions, leading to growth stunting or mortality in

some plant species.

Saskatchewan endorses the Canada-Wide Standards (CWS) for fine particulate matters (PM2.5):

• 30 µg/m3 averaged over a 24-hour period from midnight to midnight; the standard is

based on the 98th

percentile annually, averaged over three consecutive years.

Table 6 summarizes the summary statistics for continuous PM2.5 monitoring data. The

instrument uptime was greater than 99% throughout the year. The monthly average

concentrations for 1-hour average PM2.5 ranged from 1 µg/m3 to 10 µg/m

3. The maximum 1-

hour and 24-hour average concentration of 62 µg/m3 and 45 µg/m

3 were detected in July,

which were potentially due to wildfire smoke. The maximum 24-hour average was higher than

the CWS of 30 µg/m3. This event did not comprise an exceedance because the CWS is based on

the 98th

percentile of annual measurements, averaged over three consecutive years. The 98th

percentile for 24-hour PM2.5 was 15 µg/m3

for this year.

The 1-hour average PM2.5 data exhibited a seasonal trend. Between June and September, 60%

of the data was greater than the annual average of 4 µg/m3

. The percentage was significantly

higher than the remaining months (7% to 28%) indicating extraordinary source or

environmental factors were existent leading to an increased concentration. Wildfire smoke

could be one of the potential causes. Between June and September, the SESAA airshed zone

was occasionally affected by wildfire smoke. A number of high concentration events were

detected. On the other hand, the lower particulate concentration during winter and spring

27

seasons might be related to environmental factors, e.g. snow covering or rain washout would

suppress dust suspension.

Figure 7 presents the pollutant rose for 1-hour average concentration of PM2.5. Generally, the

high concentration events (e.g. >10 µg/m3

in the yellow, orange and red petals) were detected

from all wind directions. There was no significant directional trend. The detailed frequency

distribution table for the pollutant rose is presented in Appendix B, Table B-8.

2.1.8 Air Quality Index (AQI)

The Air Quality Index (AQI) is a system developed to provide the public with a meaningful and

comparable measure of outdoor air quality. The AQI uses readings from five major air

pollutants: SO2, NO2, O3, PM2.5, and carbon monoxide (CO), to calculate the AQI. A minimum of

three pollutants is required to calculate AQI. The AQI is rated in four categories: Good (0 to 25),

Fair (26 to 50), Poor (51 to 100), and Very Poor (>100). Table 7 summarizes the effects

associated with the AQI ratings.

Table 8 summarizes the occurrence hours and frequency by the AQI rating for the SESAA

continuous monitoring stations. The Weyburn AQI is calculated based on SO2, NO2, O3, and

PM2.5, as the airpointer® does not measure CO. The Glen Ewen AQI is calculated from SO2, NO2,

and O3, as the airpointer® does not measure CO or PM2.5.

The air quality at the Weyburn station was rated Good for 95.0% of the time and Fair 5.0% of

the time. In 2012, the AQI rating never fell in the Poor or Very Poor categories. During the

winter months, the AQI rating was always Good, while Fair air quality occurred between March

and September.

The air quality at the Glen Ewen station was rated Good for 96.0% of the time and Fair 4.0% of

the time. The AQI rating never fell in the Poor or Very Poor categories. In the winter months,

the AQI was rated Good, while Fair air quality occurred between May and September (note:

Glen Ewen station started operations on May 1).

Table 7. AQI rating and effect description

AQI Air Quality Rating Effect Description

0 – 25 Good

Desirable Range: No known harmful effects to soil, water,

vegetation, animals, materials, visibility or human health. The

long-term goal is for air quality to be in this range all of the time

in Canada.

26 – 50 Fair

Acceptable Range: Adequate protection against harmful effects

to soil, water, vegetation, animals, materials, visibility and human

health.

51 – 100 Poor

Tolerable Range: Not all aspects of human health or the

environment are adequately protected from possible adverse

effects. Long-term control action may be necessary, depending

on the frequency, duration and circumstances of the readings.

>100 Very Poor Intolerable Range: Continued high readings could pose a risk to

public health.

2.1.9 Air Quality Health Index (AQHI)

The 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 as the indicator of

health risk. The three pollutants are fine particulate matter (PM2.5), nitrogen dioxide (NO2), and

ground-level ozone (O3). All three pollutants are required to calculate the AQHI. Figure 8

summarizes the AQHI rating and the health messages for the at-risk population and the general

population. The health risk is classified in categories by AQHI: Low Risk (1 to 3), Moderate Risk

(4 to 6), High Risk (7 to 10), and Very High Risk (higher than 10).

Only the Weyburn station was eligible for AQHI reporting. The Glen Ewen station does not

record the PM2.5 parameter. Table 9 summarizes the occurrence statistics for AQHI rating. For

98.6% of the time, the air quality was rated Low Risk; and 1.4% was rated Moderate Risk.

Moderate Risk rating was reported between May and September.

2.2 Passive Monitoring Network

The SESAA passive monitoring program was initiated in June 2006. The objective of this

program was to collect scientifically credible air quality data for the airshed zone. The passive

monitoring network consists of 30 sampling stations, as shown in Figure 1. Among the 30

sampling stations, the two ATCO stations (No. 29 and No. 30) are in close proximity to the

Kisbey facility of the ATCO Midstream Limited for near-source monitoring; while the remaining

28 passive stations are selected for receptor and/or environmental monitoring. The AEMC

Multi-Gas Passive Samplers (MGPS) have been used in the SESAA passive monitoring program

since 2008.

The passive network was revised on August 2012. The original network included 30 stations for

SO2, 28 stations for NO2, 12 stations for O3, and 2 stations for H2S. From August, SO2, NO2, and

O3 were reduced to 15, 9, and 9 stations, respectively. H2S was increased to 6 stations. The

revised passive network added NH3 at the Creelman station (No. 20) and BTEX at the Macoun

(No. 8) and Oxbow (No. 11) stations.

The SESAA passive sampling program includes QA/QC samples to warrant the data quality. In

addition to the formal passive samples for ambient air quality monitoring, one field blank and

one replicate sample was collected each month. The field blank sample monitors filter

contamination that could be introduced during sample shipment/collection/deployment and

laboratory processes. The replicate sample is used to quantify sample variability during the

sampling and analytical procedures.

Table 10 summarizes the sample capture rate for the year of 2012. There was only one failure

sample in July due to a damaged MGPS. The sample capture rate was greater than 99% for all

parameters. The detailed passive monitoring results are presented in Appendix F.

2.2.1 Sulphur Dioxide

Figure 9 presents the 30-day average concentration for the passive SO2 network for the years

from 2008 to 2012. The concentrations within the airshed zone were quite low in comparison

to the SAAQS. There was no exceedance of the annual SAAQS (11 ppb) during the past five

years. The chart seems to show a seasonal trend that SO2 concentration was higher in winter

and early spring. In addition, it seemed to exhibit a deceasing trend over the past five years for

most months. More data is needed to validate the trends.

Figure 10 presents a bubble chart showing spatial distribution of the annual average

concentration for passive SO2. The two sampling stations near the Kisbey facility of the ATCO

Midstream Limited detected the highest concentrations of 1.2 ppb and 1.7 ppb, likely due to a

close proximity of the emission sources. For the remaining passive stations, the concentration

range was between 0.1 ppb to 0.4 ppb. Although the range of concentration was small, a spatial

trend seemed to be existent. The higher concentrations sites tended to be primarily situated in

the southern and central parts of the airshed. In this area, more industrial activities are

operating, such as coal-fired power plants and upstream oil and gas industry. In contrast, lower

concentrations were observed in the northern part of the airshed, where there is less industrial

activity.

The measured 30-day average concentrations ranged from <0.1 ppb to 3.2 ppb. Please refer to

Table F-1 for the concentrations of individual samples.

Figure 11 presents the 30-day average concentrations for the passive NO2 network for the years

from 2008 to 2012. NO2 concentration within the airshed zone was quite low in comparison to

the SAAQS. There was no exceedance of the annual SAAQS (53 ppb) during the past five years.

The chart does not show an apparent monthly or seasonal trend.

Figure 12 presents a bubble chart showing spatial distribution of annual average concentration

for passive NO2. The annual average concentrations ranged from 0.6 ppb to 3.4 ppb. The spatial

trend was not as apparent as the passive SO2. The Roche Percee station (5.1 ppb) and the

Huntoon station (5.2 ppb) tended to detect a higher concentration among the network.

The 30-day average concentrations ranged from 0.3 ppb to 10.2 ppb. Please refer to Table F-2

for the concentrations of individual samples.

2012. The data set seems to exhibit a seasonal trend that O3 concentration tended to be higher

in the spring and early-summer months. The concentration of ground-level ozone is the net

result of atmospheric formation, transport, and destruction processes. During spring and

summer, vertical mixing is stronger and could promote downward movement of upper air

ozone to the ground. However, some research suggests that there are split viewpoints as to the

relative importance of contributions of ozone from the stratosphere, mixing from the upper

troposphere, local photochemistry, and the medium and long-range transport. Further

investigation is required.


for passive O3. The annual average concentrations ranged from 24 ppb to 28 ppb. There was no

clear spatial trend within the airshed zone.

The 30-day average concentrations ranged from 15 ppb to 36 ppb. Please refer to Table F-3 for

the concentrations of individual samples.

the samples between January and July (only monitored at the two ATCO stations), there was no

apparent concentration differences among the six monitoring stations.

The 30-day average concentrations ranged from 0.3 ppb to 1.8 ppb. Please refer to Table F-4 for

2.2.5 Ammonia

Ammonia is a colourless gas with a characteristic pungent acrid-smelling odour. Ammonia is

used in industry and commerce, and also exists naturally in humans and in the environment.

Ammonia is essential for many biological processes and serves as a precursor for amino acid

and nucleotide synthesis. In the environment, ammonia is part of the nitrogen cycle and is

produced in soil from bacterial processes. Ammonia is also produced naturally from

decomposition of organic matter, including plants, animals and animal wastes.

In addition to odour nuisance, two types of potential health effects are considered important

for ammonia. Acute exposure of high concentration ammonia can cause coughing and irritation

to eyes, nasal and throat. Chronic exposure to a low concentration can reduce pulmonary

function, coughing, phlegm, wheezing or dyspnea.

The SESAA passive network started monitoring passive NH3 from August 2012 at the Creelman

station. Table 11 summarizes 30-day average concentrations for passive NH3 samples. The

measured concentrations ranged from 0.3 ppb to 1.9 ppb. More data is needed to investigate if

a temporal trend is existent.

2.2.6 Benzene, Toluene, Ethylbenzene, and Xylene (BTEX)

Benzene, toluene, ethylbenzene, and xylene are volatile aromatic compounds. These

compounds are among the most abundantly produced chemicals in the world. These

compounds occur naturally in crude oil. Other natural sources include gas emissions from

volcanoes and forest fires. The primary anthropogenic sources are through emissions from

motor vehicles, aircrafts, and cigarette smoke. BTEX compounds are created and used during

the processing of petroleum products and during the production of consumer goods such as

paints and lacquers, thinners, rubber products, adhesives, inks, cosmetics and pharmaceutical

products.

BTEX exposures have been associated with skin and sensory irritation, central nervous system

depression, and effects on the respiratory system. Prolonged exposure to these compounds can

affect kidney, liver and blood systems. Benzene is a known carcinogen. Workers exposed to

high levels of benzene were found to have an increased incidence of leukemia.

THE SESAA passive network started monitoring passive BTEX from August 2012 at the Macoun

and Oxbow stations. Table 12 summarizes 30-day average concentrations of passive BTEX

samples. The measured concentrations were less than 1 ppb for benzene and toluene. All

ethylbenzene and xylene samples were less the method detection limit of 0.2 ppb.
