G1 Introduction This appendix provides supporting information for the response to SIR 20.

In this appendix, the Updated Project Case air quality predictions are compared with the environmental impact assessment (EIA) Project Case predictions in the Integrated Application, Volume 2, Section 3, Appendix 3D. More specifically, the goals of this updated air quality assessment are:

• to summarize the design changes (see Section G3)

• to compare air quality changes associated with those presented in the Project Case in the EIA with the Updated Project Case (see Section G4)

The requirement for a full reassessment of the Base Case, Application Case and Planned Development Case is determined based on comparison of the EIA Project Case with the Updated Project Case, i.e., incremental change.

G2 Methods Methods used to estimate air quality changes due to updated design were identical to those described in the Integrated Application, Volume 2, Section 3.4.

G3 Updated Project Emissions Updated design information that can influence the ambient air predictions in the EIA includes changes to the following:

• project fenceline (i.e., project development area [PDA] boundary) • plot plan • stack emissions • tank emissions • process area emissions

G3.1 Project Fenceline The EIA provided maximum concentration predictions within and outside the project fenceline (PDA boundary), for which the Alberta Ambient Air Quality Objectives (AAAQO) are applicable. A change in the location of the fenceline can change the corresponding concentration predictions. For a comparison of the EIA fenceline with the updated fenceline, see Figure G3.1-1. The main change is along the southern boundary.

G3.2 Plot Plan Ambient concentration predictions depend on the distance between the emission source and the receptor, and for multiple emission sources, on the orientation of emission sources relative to wind direction. These factors influence ambient concentrations more strongly in the near field (i.e., within 5 km).

The CALMET model was applied using 1-km grid cell spacing, and meteorological parameters for adjacent cells can change slightly. On this basis, moving a stack from one CALMET grid cell to another can change the trajectory of a plume and this can influence ambient concentrations at more distant locations.

EIA PROJECT CASE UPDATED PROJECT CASE



As the upgrader plot plan is approximately 2.5 km by 2.5 km, the updated facility design results in some emission sources moving from one CALMET grid cell to another.

For a comparison of the upgrader stack locations in the EIA design with those associated with the updated facility design, see Figure G3.2-1. The stacks, in general, have moved from the western portion of the site to the northern portion.

For a comparison of project tank locations in the EIA design with those associated with the updated facility design, see Figure G3.2-2. The tanks, in general, have moved from the western portion of the site to the central portion.

For a comparison of the upgrader process area locations in the EIA design with those associated with the updated facility design, see Figure G3.2-3. The process areas, in general, have moved from the western and eastern portions of the site to the west half of the site.

G3.3 Stack Emissions As discussed in the response to SIR 63b, the sulphur (S) content of the plant fuel gas was reduced from 368 ppmv to 86 ppmv (see Table G3.3-1). This reduces the SO2 emissions from the EIA design for the boiler, heater and furnace stacks.

For a comparison of the stacks assumed for the EIA design with those associated with the updated facility design, see Table G3.3-2. Five stacks have been removed and seven stacks have been added as part of the updated facility design. Stacks removed include:

• five coker heaters (H201, H202, H301, H302, H401 and H402) • one flare stack (50MF1) • one DHT stripper fed furnace (F103)

The seven new stacks include:

• two coker heaters (12-F-101 and 12-F-201) • one utility boiler (40-F-105) • two fractionators feed heater (14-F-101A and B) • two new flare stacks (smokeless HC and non-smokeless HC flare)

The updated facility design has also resulted in slight changes in the heat capacity for some units. As the heat input was used to estimate the emission rates for many of the contaminants, the updated facility design will change the corresponding emission rates.

For updated source and emission information for the stacks, see Table G3.3-3 to Table G3.3-8. For updated source and emission parameters for normal operations, see Table G3.3-9, and for the upset scenario, see Table G3.3-10.

G3.5 Process Area Emissions In the EIA Project Case, the API separator was assumed to be not covered. For the Updated Project Case, the API separator is assumed to be covered and blanketed with nitrogen gas. The nitrogen gas will be vented through a carbon adsorber before discharge to the atmosphere. On this basis, fugitive emissions from the API separator are assumed to be negligible.

No other changes with respect to the fugitive emission rates were associated with the updated facility design. As indicated in Figure G3.2-3, tank process areas P, Q, R and S were arranged in a single area.



G3.6 Comparison of EIA and Updated Project Emissions For a comparison of EIA project emissions with those associated with the updated facility design, see Table G3.6-1. The comparison indicates that:

• SO2 emissions associated with the upgrader have decreased by 13 to 27%, depending on the averaging period and the corresponding sulphur recovery assumption. The reduced sulphur content in the fuel gas has reduced combustion SO2 emissions from 5.1 to 1.3 t/d (a decrease of 3.8 t/d).

• NOX, CO and PM2.5 emissions have increased by about 7 to 8%, due to increased fuel consumption. The increases are slightly different for each substance since the emission factors applied to conventional burners are different from those applied to flare stacks.

• VOC emissions have increased by 8% due to increased fuel consumption and due to changes in assumptions about the requirement for vapour recovery on some tanks described in the Integrated Application (see also the response to SIR 66a and SIR 66f).

• greenhouse gas emissions from combustion and fugitive sources have increased by 8%, primarily due to increased fuel consumption

• water vapour emissions from the cooling tower facilities have decreased by about 2%

Table G3.6-1 also compares the EIA and updated project emissions for selected VOC and total reduced sulphur (TRS) compounds. These compounds were selected to represent the VOC and TRS groups since they were identified in the Human Health Risk Assessment (HHRA) in the Integrated Application, Volume 2, Section 14, as having relatively high exposure ratios. The following section evaluates the air quality implications of these emission source changes relative to those provided in the EIA Project Case.

NOTES:

Table 3.7-1 (p 3-25 in the Integrated Application, Volume 2) provides an emission summary for the upgrader based on the EIA design.

The methane emissions identified in Table 3.7-1 from the storage tanks are incorrect as they were based on preliminary design information. The revised values in Table G3.6-1 correctly reflect the EIA design.

The storage tank and process area VOC/PAH emissions in Table 3.7-1 were not presented on an equivalent basis with respect to stack emission estimates. The revised values in Table G3.6-1 include all non-methane hydrocarbons.

As in Table 3.7-1, the CO2 and CO2e emissions do not include the steam methane reformer contribution (i.e., 6152 t/d CO2). With this contribution the CO2e emissions for the EIA and updated designs are 14,938 and 15,631 t/d, respectively. This represents an increase of 5%.



G3.7 Summary Updated design information that can affect the ambient air quality predictions for the EIA Project Case includes:

• updated fenceline (PDA) and updated plot plan – have resulted in updated stack, tank and process area locations

• updated stack parameters – the sulphur content in the fuel gas has been reduced, five stacks have been removed and seven have been added, and slight changes in heat capacity will affect emission rates

• updated tank parameters – three tanks have been removed and three tanks have been added, and the design, size and vapour pressure values for the tanks have been revised, changing the emission rates

• updated process area parameters. – the API separator will no longer be a source of fugitive emissions since it will be covered, and blanketed with nitrogen gas, and the blanket will be discharged through a carbon adsorber before atmospheric discharge

For a summary of project emission changes, see Table G3.7-1.

Key emission changes are as follows:

• SO2 emissions have decreased due to the reduced sulphur compound content in the fuel gas.

• NOX, PM2.5, CO and greenhouse gas emissions have increased due to the change in firing capacities.

• VOC emissions have increased by 8%, primarily due to increased fuel consumption and due to changes in assumptions about the requirement for vapour recovery on some tanks described in the Integrated Application.

G4.1.1 SCREEN3 Predictions The SCREEN3 model was used in the EIA to evaluate maximum ground-level SO2 and NOX concentrations from each of the project stacks. For a comparison of the maximum predicted concentrations associated with the EIA stack assumptions with the updated stack assumptions, see Table G4.1-1. As in the EIA, the maxima for the individual stacks were added to provide an indicator of the combined facility maximum even though the individual maxima occur in different locations and may occur at different times. The results demonstrate that:

• the maximum SO2 concentration for each boiler/heater type of stack decreases due to the reduced sulphur content of the fuel gas

• the maximum SO2 concentrations due to the thermal oxidizer stack remains the same as the parameters for this stack did not change

• the total maximum SO2 concentration decreases from 414 µg/m3 to 269 µg/m3; this is a decrease of 35%

• the maximum NOx concentration for each boiler/heater type of stack show some increases and some decreases, depending on the direction of the fuel gas consumption change

• total maximum NOX concentrations increase from 219 µg/m3 to 236 µg/m3, an increase of 8%, primarily due to an additional utility boiler

The maximum predicted SO2 concentration due to the upgrader (for both the EIA Project Case and Updated Project Case) is less than the 1-h average AAAQO of 450 µg/m3. If all NO is conservatively assumed to be in the form of NO2, then the maximum predicted NO2 concentration due to the upgrader (for both the EIA Project Case and updated Project Case) is less than the 1-h average AAAQO of 400 µg/m3.

NOTES: The 1-h SO2 predictions due to the incinerator stacks are based on 1.4 times the 99.4% sulphur recovery efficiency. Assuming 100% NOX to NO2 conversion, the predicted 1-h NOX concentration can be compared with the NO2 AAAQO.



G4.1.2 CALPUFF Maximum Predictions The CALPUFF model was used in the EIA to evaluate maximum ground-level SO2 and NOX concentrations from the combined operation of all the project stacks (see the Integrated Application, Volume 2, Appendix 3D). For predictions for the EIA Project Case and Updated Project Case, see the following tables:

• Table G4.1-2 compares the maximum predicted SO2, NO2, PM2.5, CO, and VOC concentrations, and the potential acid input (PAI) deposition values that are predicted to occur inside the respective fencelines for the two cases.

• Table G4.1-3 compares the maximum predicted SO2, NO2, PM2.5, CO, and VOC concentrations, and the PAI deposition values that are predicted to occur along the respective fencelines for the two cases.

• Table G4.1-4 compares the maximum predicted SO2, NO2, PM2.5, CO, and VOC concentrations, and the PAI deposition values that are predicted to occur outside the respective fencelines for the two cases.

NOTE: Bold face text indicates predicted increases relative to the EIA Project Case. Predictions exclude receptors within the property boundary of other facilities for consistency with the EIA Project Case.



The predicted differences for the two cases depend on the changes in the emission parameters, the locations of the emission sources and the location of the receptors. As the AAAQO are applicable at and outside the fencelines, the following general comments apply in this context:

• Maximum predicted SO2 concentrations for the Updated Project Case are predicted to decrease (by -8 to -67%) for all averaging periods. The maximum predicted PAI deposition for the Updated Project Case also decreases (by -29 to -31%). The predicted concentration and PAI deposition decreases are consistent with the SO2 emissions that decrease by 13 to 27%.

• Maximum predicted NO2 concentrations for the Updated Project Case decrease (by -3 to -14%) for the 1-h and annual averaging periods and increase (by 4%) for the 24-h averaging period. The NO2 emissions associated with the Updated Project Case increase by 8%.

• Maximum predicted PM2.5 concentrations for the Updated Project Case are predicted to decrease (by -6 to -20%) for all averaging periods. While the primary PM2.5 emissions associated with the Updated Project Case increase by 8%, precursor SO2 emissions decrease by 13 to 27%.

• Maximum predicted CO concentrations for the Updated Project Case generally decrease (by -6 to -17%); however, there is an increase (by 4%) for the 1-h averaging period along the fenceline. The CO emissions associated with the Updated Project Case increase by 7%.

• Maximum predicted VOC concentrations for the Updated Project Case generally decrease (by -9 to -17%); however, there is an increase (by 6%) for the 1-h averaging period along the fenceline. The VOC emissions associated with the Updated Project Case increase by 8%.

G4.1.3 CALPUFF Maximum Predictions for the Human Health Risk Assessment For the Human Health Risk Assessment (HHRA) receptor locations, maximum predicted concentrations associated with each receptor class for the EIA Project Case were compared with the Updated Project Case. For a comparison of maximum predicted SO2, NO2, PM2.5, CO, acetaldehyde, acrolein, formaldehyde, H2S, 1,3-butadiene and benzene concentrations for the two cases, see Table G4.1-5 and Table G4.1-6.

The following describes the use of receptors in the air and HHRA:

• The HHRA provided an assessment for six receptor groups (i.e., Agricultural, Residential, Industrial, Public Use Areas, Monitoring and Fenceline). While the air quality assessment evaluated these six receptor types, the air quality assessment section of the EIA presented results for only four of these receptor groups:

• Agricultural/Residential (i.e., Agricultural) • Residential/Community (i.e., Residential) • Commercial/Industrial (i.e., Industrial) • Public Access (i.e., Public Use Areas)

• The HHRA conservatively included Agricultural receptors located within the property lines of planned development projects. The air quality assessment section of the EIA excluded these receptors from the analysis.



For this updated project assessment, the receptor groups and Agricultural receptors are consistent for both the updated air quality assessment and updated HHRA.

Results of the EIA Project Case and Updated Project Case comparison for each receptor group are as follows:

Agricultural/Residential Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include NO2 (24-h, 16%), 1,3-butadiene (all averaging periods, 30 to 68%) and methylene chloride (1-h and annual, 47% and 53%).

While the maximum H2S concentrations are predicted to decrease, the maximum 1-h and 24-h H2S concentrations are still predicted to exceed the respective AAAQO of 14 and 4 µg/m3. These maximum concentrations are predicted to occur at an agricultural receptor located within a planned development north of the upgrader.

Maximum 1-h H2S concentrations of 13 to 14 µg/m3 are predicted to occur at two agricultural receptors south of the upgrader. One exceedance per year is predicted to occur at one of the receptors. The 24-h AAQO is predicted to be exceeded 2 and 4 days per year at this receptor. Similar values were predicted for the EIA Project Case.

Residential/Community Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include 1,3-butadiene (all averaging periods, 28 to 43%) and formaldehyde (1-h, 12%).

Commercial/Industrial Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include NO2 (annual, 27%), PM2.5 (24-h, 13%), 1,3-butadiene (1-h and annual, 24 and 68%), acetaldehyde (annual, by 29%), acrolein (annual, 27%), formaldehyde (1-h and annual, 16 and 68%) and methylene chloride (1-h and annual, 22 and 37%). The highest increases are predicted to occur at a nearby industrial receptor adjacent to the southern boundary of the upgrader site.

While the maximum H2S concentrations are predicted to decrease, the maximum 1-h and 24-h H2S concentrations are still predicted to exceed the respective AAAQO of 14 and 4 µg/m3. The maximum 1-h concentration is predicted to occur at an industrial facility north of the upgrader. The maximum 24-h concentration is predicted to occur at an industrial receptor adjacent to the southern boundary of the upgrader site.

Public Access Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include NO2 (24-h, 12%), 1,3-butadiene (all averaging periods, 51 to 60%) and methylene chloride (1-h and 24-h, 14 and 17%). The highest increases are predicted in the Astotin Natural Area.



Monitoring Station Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include NO2 (annual, 11%), 1,3-butadiene (1-h, 12%), acetaldehyde (annual, 13%), acrolein (annual, 12%) and formaldehyde (annual, 22%). The highest increases are located at the Range Road 220 and Scotford monitoring stations, which are the closest monitoring stations to the PDA.

Fenceline Group There are increases and decreases for these receptors, depending on the substance and the averaging period. Maximum values that increase by 10% or more include 1,3-butadiene (1-7, 10%, annual, 16%), formaldehyde (1-h, 37%) and methylene chloride (1-h and annual, 25 and 82%).

While the maximum H2S concentrations are predicted to decrease, the maximum 1-h and 24-h H2S concentrations are still predicted to exceed the respective AAAQO of 14 and 4 µg/m3. The maximum concentrations are predicted to occur along the northern boundary of the upgrader site.

Summary This comparison focused on comparing maximum values associated with the EIA Project Case and Updated Project Case. These maximum values are only one indicator of the predicted concentration changes associated with the two project cases. An indicated decrease in the tables might not mean a decrease at every receptor, and an indicated increase in the tables might not indicate that reductions do not happen at some receptors. Only increases of 10% or more have been flagged in the text; as indicated in the tables, there are also substantial decreases.

For a discussion of the implications of these changes on human health, see Appendix H.

G4.1.4 CALPUFF Predictions for Spatial Plots The CALPUFF model was used to predict the spatial concentration variation for the EIA Project Case and Updated Project Case. The predicted concentrations have been superimposed over a 50 by 50 km base map and are compared in the Figure G4.1-1 to Figure G4.1-10.

SO2 Predictions For the predicted maximum 1-h average SO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-1. For most of the model domain, the Updated Project Case predictions are generally 80% to 90% of those associated with the EIA Project Case. There are isolated locations where the changes are in the 60% to 70% range, and isolated locations where the changes are in the 100% to 110% range.

For the predicted maximum 24-h average SO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-2. The Updated Project Case predictions are generally 60% to 90% of those associated with the EIA Project Case. There are isolated locations where the changes are in the 50% to 60% range, and one location where the changes are about 130%.

For the predicted annual average SO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-3. The Updated Project Case predictions are generally 40% to 60% of those associated with the EIA Project Case. In the southeast corner of the RSA, the changes are in the 60% to 70% range.

NO2 Predictions For the predicted maximum 1-h average NO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-4. The Updated Project Case predictions are generally 100% to 120% of those associated with the EIA Project Case. South of the PDA, the changes are generally in the 90% to 100% range

For the predicted maximum 24-h average NO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-5. The Updated Project Case predictions are generally 100% to 120% of those associated with the EIA Project Case. There are isolated locations where the changes are in the 70% to 100% range, and several locations to the southwest where the changes are in the 130% to 150% range.

For the predicted annual average NO2 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-6. The Updated Project Case predictions are generally 100% to 120% of those associated with the EIA Project Case. Southwest of the PDA, the changes are in the 70% to 100% range.

PM2.5 Predictions For the predicted 98th percentile 24-h average PM2.5 concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-7. The Updated Project Case predictions are generally 80% to 100% of those associated with the EIA Project Case. In isolated areas south of the PDA, the changes are generally in the 100% to 110% range.



CO Predictions For the predicted maximum 1-h average concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-8. The Updated Project Case predictions are generally 100% to 120% of those associated with the EIA Project Case. South of the PDA, the changes are generally in the 90% to 100% range.

For the predicted maximum 8-h average concentrations for the EIA Project Case and Updated Project Case, see Figure G4.1-9. The Updated Project Case predictions are generally 100% to 120% of those associated with the EIA Project Case. There are isolated locations where the changes are in the 70% to 100% range, and several locations to the southwest where the changes are in the 130% to 150% range.

PAI Deposition Predictions For the predicted annual PAI deposition for the EIA Project Case and Updated Project Case, see Figure G4.1-10. The Updated Project Case predictions are generally 70% to 80% of those associated with the EIA Project Case.

G4.2 Upset Stack Predictions Four upset flaring scenarios were identified in the EIA Project Case (see the Integrated Application, Volume 2, Appendix 3E.2.3). For the Updated Project Case, one of these scenarios has been removed (Scenario 1) and two new scenarios have been added (Scenario 5 and Scenario 6). These changes are due to updated stack design. Specifically, the 50MF1 HP/LP flare stack has been replaced with two new flare stacks (i.e., smokeless HC and non-smokeless HC flare stacks). The parameters for the three acid-gas scenarios (Scenario 2 to Scenario 4) have been updated.

G4.2.1 SCREEN3 Predictions For a comparison of the EIA and updated flaring scenario predictions, see Table G4.2-1. The comparison demonstrates that:

• maximum predicted SO2 concentrations for the three acid-gas flaring scenarios decrease

• maximum predicted SO2 concentrations associated with the two new scenarios are less than the AAAQO

G4.2.2 CALPUFF Predictions For a comparison of the EIA and updated scenario predictions, see Table G4.2-2. The comparison demonstrates that:

• maximum predicted SO2 concentrations for the three acid-gas flaring scenarios decrease

• maximum predicted SO2 concentrations associated with the two new scenarios are less than the AAAQO

G5 Summary and Conclusions

G5.1 Summary The CALPUFF model approach described in the EIA was used as the primary assessment tool to evaluate the air quality changes in the EIA Project Case and Updated Project Case. The results can be summarized as: • Maximum predicted SO2 concentrations for the Updated Project Case are predicted

to decrease (by -8 to -67%) for all averaging periods. • Maximum predicted NO2 concentrations for the Updated Project Case decrease (by -3

to -14%) for the 1-h and annual averaging periods and increase (by 4%) for the 24-h averaging period.

• Maximum predicted PM2.5 concentrations for the Updated Project Case are predicted to decrease (by -6 to -20%) for all averaging periods. While the primary PM2.5 emissions associated with the Updated Project Case increase by 8%, precursor SO2 emissions decrease by 13 to 27%.

• Maximum predicted CO concentrations for the Updated Project Case generally decrease (by -6 to -17%); however, there is an increase (by 4%) for the 1-h averaging period along the fenceline. The CO emissions associated with the Updated Project Case increase by 7%.

• Maximum predicted VOC concentrations for the Updated Project Case generally decrease (by -9 to -11%); however, there is an increase (by 6%) for the 1-h averaging period along the fenceline. The VOC emissions associated with the Updated Project Case increase by 8%.

• Maximum predicted PAI deposition for the Updated Project Case also decreases (by -29 to -31%). The predicted PAI deposition decrease is consistent with the annual SO2 emissions that decrease by 27%.

For the maximum concentrations predicted in the HHRA locations, there are increases and decreases, depending on the receptor type, the substance and the averaging period. Generally, maximum NO2, 1,3-butadiene and formaldehyde concentrations were predicted to increase by 10% or more at some residential and agricultural locations. While the H2S emissions were remain unchanged, there are still predicted exceedances of the H2S AAAQO near the Project fenceline.

For upset flaring, maximum predicted SO2 concentrations for the three updated acid-gas flaring scenarios decrease and maximum predicted SO2 concentrations associated with the two new scenarios are less than the AAAQO.

G5.2 Conclusions The Updated Project Case predictions for SO2, PM2.5 and PAI decrease compared with the EIA Project Case. Though there are some predicted NO2 and CO concentration increases due to the Updated Project Case predictions, the levels associated with the EIA Project Case and Updated Project Case are much less than the respective AAAQO. Concentrations for some VOC and TRS substances due to the Updated Project Case are predicted to increase in some locations. The key conclusions in the Integrated Application, Volume 2, Section 3.11 remain unchanged despite the changes in upgrader air emissions. Therefore, Application Case and Planned Development Case assessments are not considered necessary to understand the implications of the updated project.
