EXECUTIVE SUMMARY

Clearstone Engineering Ltd. conducted field studies at the Baytex Reno Field from February 26 to March 6, 2013 for purposes of characterizing atmospheric emissions and completing an emissions inventory for purposes of air quality modeling. The Reno Field consists of 23 operational cold heavy oil production pads with 41 individual wells, one water injection facility and one gas plant. Emission sources include lift pump engines, compressor engines, tank heaters, tank vents, flares and one incinerator. Emissions from these locations were included in the inventory.

To characterize emissions, Clearstone conducted flow measurement of produced fluids and solution gas vented to atmosphere or directed to flare. Casing gas, solution gas and combustion device flue gas samples were collected and submitted to the Alberta Innovates Technology Futures laboratory for comprehensive analysis. Operational data was recorded or subsequently obtained from Baytex for the test period and for the month of February 2013.

Gas streams were sampled using two types of sampling trains. Fixed gases, C1 to C4

hydrocarbons, volatile hydrocarbons and reduced sulphur compounds were sampled using a SilicoCan™ canister sampling train. Semi-volatile compounds were sampled using a PUF sampling train. The analytical protocols quantified over 160 substances.

A material balance, considering all fuel and flue gas substances identified, was completed for each combustion source type to determine the actual air to fuel ratio, combustion efficiency and flue gas to fuel gas ratio. Based on the results of these material balances,emission factors for all substances observed in the flue gas were determined and expressed in terms of mass emission per unit of energy input to the combustion device.For NOx, CO and PM published emission factors were applied to the combustion sources to complete the emission profile. Following this procedure, emission factors were determined for the lift pump and compressor engines and for the tank heaters.

Tank emissions were determined through the measurement of vent gases from 10 production facilities. The vent gas flow rate of the first production tank was measured using an ultrasonic flow measurement device. Measurements provided flow velocity, temperature and pressure, and assuming saturated conditions the dry gas vent rate was calculated. Vent gas sample analyses were used to correct the vent gas flow rate to an air-free dry flow rate and to determine emission factors. The dry air-free flow rate and the production data provided by Baytex were used to determine the vent gas GOR during the test period. The gas analyses were used to determine emission factors for all vented substances.

iv

Based on the tests completed:1. Emission factors were developed for two operating scenarios:

a. Solution Gas venting where only solution gas associated with oil production was vented

b. Mixed Casing and Solution Gas venting where excess casing was directed to the top of the production tank and after mixing with the solution gas, was vented.

2. Average vent gas GOR ratios were determined for two operating scenarios:a. Solution Gas GOR, based on three tests, averaged 1.45 dsm3 gas/m3 oilb. Mixed casing and Solution Gas GOR, based on seven tests, averaged

51.1 dsm3 gas/m3 oil

In addition to the above, odour measurement data determined by RWDI was processed and expressed as odour units per dsm3 air-free vented gas. Raw data was sorted to develop odour emission factors for Solution Gas and Mixed Casing and Solution Gas.

Based on these results and production data provided by Baytex Energy Ltd., a complete emissions inventory for the Reno Field was compiled for the existing operations for February 2013. The inventory includes all production pads, the water injection or disposal facility and the gas plant where surplus gas in delivered to TCPL. The emissions inventory provides emissions for all compounds identified in grams per second and is source type and location specific. The inventory is contained in a data file suitable for application in dispersion modeling studies.

For this inventory, Combustion device emissions were based on the determined emission factors and the calculated fuel consumption of each device. Tank vent emissions were based on the applicable emission factors, the reported average daily oil production rate and a field vent gas GOR of 51 as specified by Baytex. The applied GOR is comparable to the value determined for those wells where mixed casing and solution gas was vented and considerably greater than the value determined for those wells where solution gas was vented. All hydrocarbon gas emissions were assumed to be released from the first production tank.Flare and incinerator combustion efficiencies of 98% and 99.5% respectively,were applied at those locations where vented gases were directed an emission control device.

1 INTRODUCTION

Baytex Energy Ltd. (Baytex) operates heavy oil production facilities at the Reno Field southeast of Peace River Alberta. Reno Field operations are referred to as cold heavy oil production with wells and production facilities located at production pads. The production pads include one or more multi-leg horizontal production wells operating at depths of about 600 meters to recover oil from the Bluesky formation.

Surface facilities include wellheads equipped with hydraulically driven lift pumps and flow lines delivering the produced fluids to, typically, two production tanks operating in series. The production tanks are maintained at 70 to 80C with casing gas-fired, in-tank, tube heaters to facilitate fluid transportation. The produced fluids include oil, water, sand and solution gas. Solution gas disengages from the oil in the production tank and is either vented to atmosphere or sent to flare. Oil, water and sand production is removed from the production tanks and loaded into trucks for disposition to sales or disposal. Some water is recycled back into the producing wells.

Casing gas is produced at each well and is directed into a line held at a pressure of 35-70 kPa to provide fuel gas for the pad. The casing fuel gas is used for hydraulic drive lift pump engines, compressor engines, tank heaters, flare pilots and sweep gas. Where possible, the excess gas is directed through a small compressor into a gas gathering system. At the one site not connected to the gas gathering system, casing gas is used as fuel and any excess is directed to the production tank. Casing gas directed to production tanks is vented to atmosphere or to an emission control device. Some sites include separators to remove liquid from the casing gas and some include methanol injection facilities. Both methods are used for control of line freezing.

One of the production units at a production pad tested during the field study, with wellhead (RHS), gas engine for hydraulic motor drive (by wellhead), four production tanks (centre) and flare stack (LHS), is shown in Figure 1. A second production unit on the adjacent pad is shown in the background. The locations of production pads in the Reno Field are shown in Figure 2.

All surplus casing gas flows to the gas processing facility located at 10-22-79-20W5 via a gas gathering system (ABGS0003592). The gas plant includes a compressor and dehydrator. The gas is compressed, water removed and delivered into the TCPL pipeline. In the event that flaring is required, it occurs at the production pads, not at the gas plant.

The Reno Field production pads are listed in Table 1. The operation includes 23 pads with a total of 41 wells of which four are shut in. The number of wells at each pad is indicated along with the number of tanks, casing gas compressors and hydraulic drive engines. Tanks in use are heated using casing gas. In addition, there is one water injection location consisting of one disposal well, three unheated water tanks, all with open vents to atmosphere.

In an effort to characterize these operations, Clearstone Engineering Ltd. conducted a casing gas, solution gas and vent gas measurement and sampling program in February 2013. Fuel, flue and vent gas samples collected were analyzed of fixed gases, C1 to C4 hydrocarbons, sulphur compounds and volatile compounds. Ambient air samples collected with a polyurethane foam sampling system were analyzed for semi-volatile compounds including polycyclic aromatic hydrocarbons. Flow measurements were made using ultrasonic flow and radar measurement equipment. In addition, relevant operating conditions at sample locations were recorded.

To supplement these field study results, the results of a tank vent gas study conducted at Pads 8-31 and 10-12 in July 2012 are included. The scope of work for this study included gas flow measurements and emission characterization similar to the February study.

2 SCOPE OF WORK

Compilation of the inventory of atmospheric emissions associated with the Reno Field included the following tasks:

Delineation of all fuel consuming devices and determining their emissions. This was completed by listing all combustion devices at each pad, documenting fuel consumption,estimating some emissions based on published emission factors and the calculating mostemissions based on site specific sampling.Collection of fuel, flue and process stream samples and completion of detailed analysis to facilitate the determination of site specific emission factors.Determination of vented, flared or incinerated casing and solution gas flow rates associated with site specific production.Determination of semi-volatile emissions based on sampling and analysis.Observation and qualitative reporting of fugitive emissions using an infrared camera.

Table 2 summarizes the target fuel, flue and process gas streams by source type and the well pad identity. A total of 19 samples were collected and analyzed. One sample was contaminated and not acceptable.

Upon receipt of all analytical results, the data were processed to develop site specific emissions factors for lift pump and compressor engines, and for gas-fired tank heaters. These site specific factors along with published emission factors were used to develop a comprehensive emission inventory for each production pad. Flare and incinerator emissions were based on assumed combustion efficiencies and average gas composition results.

3 METHODOLOGIES

3.1 FLOW MEASUREMENTS

Process fluid flow measurements including production from wellhead to production tank and solution gas vented from production tanks was attempted at various pads using ultrasonic flow measurement devices. In addition, fluid production rate measurements were attempted using a thief hatch mounted microwave liquid level radar system.

3.1.1 OIL FLOWFluid (oil and BS&W) flow was attempted using a clamp on ultrasonic flow measurement device. Of six measurement attempts only one was considered to be acceptable and close to the production rate reported by Baytex. The microwave radar tank top measurement device was attempted at the seven locations with similarly poor results. The measurement results are not used in any calculations. All production rates used in calculations are those reported by Baytex and these are included as fluid production and oil production with the difference being BS&W.

3.1.2 SOLUTION GASUltrasonic gas flow measurements of solution gas were completed at 10 locations in February 2013. Wet gas was measured and corrected to dry gas based on the temperature measured at the ultrasonic device location and local barometric pressure. Due to the prevailing weather conditions the gas temperature at the flow measurement location was lower that the tank vapour space temperature and consequently water vapour was condensed in the 4-inch sample line connected to the top of the tank and the 3-inch flow measurement cell. The condensation did not affect flow measurement but the condensed water vapour is not included in the wet flow rate. In all cases, the first tank in the production train was sampled as it exhibited the higher visual emission rate. The second tank exhibited considerably lower emissions. No estimate of the secondary emission rate was attempted and emissions reported are based on the single tank measurement.

3.2 SAMPLING SYSTEMS

Two sampling methods were required to achieve the objectives of the study. Volatile (VOC) and reduced sulphur (RSC) compounds and inert gases were sampled using an evacuated canister sampling train. For Semi-volatile compounds a polyurethane filter (PUF) sampling train. In both cases, the field collected samples were returned to the AITF laboratory for detailed analysis. The two methods are briefly described below.

3.2.1 INERT, VOLATILE AND REDUCED SULPHUR COMPOUNDSThe canister sampling train is shown in Figure 3. It includes a probe, for insertion into the source,a valve and a SilicoCan™ canister. The SilicoCan™ canister is supplied clean and evacuated. The source is sampled by slowly opening the valve after the probe is inserted in to the source duct opening. The canister fills with the sampled gas to a pressure equal to the local barometric

pressure. Local pressure and source temperature are noted. The canister is returned to the laboratory for analytical work based upon the prescribed protocol. The container is heated to approximately 15°C above the recorded source temperature prior to recover of sample for analyses. The sample train is based upon NCASI Method IM/CAN/WP-99.02 but does not include the impinger gas conditioning components.

Figure 3. Inert, VOC and RSC canister sampling train schematic.

3.2.2 SEMI-VOLATILE SAMPLING TRAINThe PUF sampling train includes impingers to remove condensable water prior to the samples gas passing through the PUF where semi-volatile compounds are trapped. After the water and semi-volatiles are removed the dry gas flows through a meter where the dry volume is measured and recorded. The sample is drawn through the sample train by a vacuum pump. The sampling train is shown schematically in Figure 4.

3.3 ANALYTICAL PROTOCOLS

Analytical work completed by Alberta Innovates followed prescribed protocols as outlined below.

3.3.1 FIXED GASES, VOC AND RSH PROTOCOLThe fixed gases, volatile and reduced sulphur compound analytical work included the quantification of numerous other organic compounds. The analytical procedure and lower detection limits used for the RSC/VOC/C1C4/Inert scans are:

3.4 EMISSION FACTOR DEVELOPMENTTwo methods were used to compile the emission inventory. For site specific emissions identified through the sampling program a combustion process material balance was applied. For NOx, CO and PM, USEPA Method 19 and ASTM D3588-91, along with published emission factors were applied.

3.4.1 COMBUSTION PROCESS MATERIAL BALANCEA simple combustion process is defined as one where the only input streams were fuel gas andcombustion air and the only output was a single flue gas stream. For this process, a material balance calculation was completed for all compounds identified in the fuel gas and the flue gas. Typically, the fuel gas contained about 100 compounds, some of which were present in the flue gas. Typically, the flue gas contained about 50-100 compounds, some of which were not present in the fuel gas and assumed to be manufactured in the combustion process.

Fuel gas was corrected for potential air contamination during the sampling process by removing all oxygen and the associated nitrogen. The remaining composition was normalized and used in the material balance calculation. Air was assumed to be pure oxygen and nitrogen with no organic compound contamination. Flue gas analytical results were receive on a dry basis and could not be corrected for potential air contamination. The dry basis oxygen content was used as the key to complete the material balance.

The EXCEL spreadsheet based material balance program balanced flue gas oxygen content with measured oxygen content. The material balance program allowed for partial destruction of all fuel gas compounds and the creation of new compounds measured in the flue gas. The program was manually managed though two or more iterations to produce the final material balance.

3.4.2 METHOD FOR NOX, CO AND PMThis method is based on the calculation of compressibility, higher heating value, specific gravity and gross calorific as outlined in ASTM D3588-91 (60F (15.6C) @ 1 atm) and F Factor based on USEPA 40 CFR, Part 60, Appendix A, Method 19. This procedure determines is based on fuel composition, combustion source type characteristics and the application of published emission factors that are based on energy input.

3.5 COMBUSTION EFFICIENCY

Combustion efficiency was considered to be an important indicator of performance and was determined in various ways for each source sampled. Combustion efficiency not only indicated the fuel efficiency but may be an indicator of poor substance destruction or the potential formation of unwanted substances in the flue gas emissions.

The calculation methods for the three combustion efficiencies are:

CETOC =( , ) ( , )( , ) 100% (Equation 3.1)

Where:CETOC is the total organic carbon based combustion efficiencyCinlet,nonCO2 is the TOC in the inlet fuel gas excluding carbon dioxideCoutlet,nonCO2 is the TOC in the outlet flue gas excluding carbon dioxide

This method was used to make sure that all compounds identified in the fuel and flue gases were accounted for in the combustion efficiency calculation.

CECH4 = ( ) ( )( ) 100% (Equation 3.2)

Where:CECH4 is the total methane based combustion efficiencyCH4inlet is the methane in the inlet fuel gasCH4outlet is the methane in the outlet flue gas

This method considered methane to be a basic indicator of combustion efficiency.

CETHC = ( , ) ( )( , ) 100% (Equation 3.3)

Where:CETHC is the total hydrocarbon based combustion efficiencyCinlet,nonCO2 is the inlet gas without carbon dioxideTHCoutlet is the outlet total hydrocarbon

This method approximates the traditional use of a THC combustion analyzer to determine combustion efficiency.

4 FIELD MEASUREMENT RESULTSDuring the February 2013 field sampling period, the operational details for the wells studied are summarized in Table 4. Key information includes oil production, and casing and solution gas GORs. Data provided is for the day that the location was studied and does not necessarily represent a monthly or yearly average. Typically, all casing gas not used as fuel or delivered to the gas gathering system is directed to one production tank. Consequently, the observed release rate to atmosphere or to flare/incinerator cannot be related to the production well associated with the production tank in question.

4.1 VENT GAS FLOW MEASUREMENTSTank vent flow measurements, using the ultrasonic flow measurement device, were attempted at ten locations and successful at eight. The results are summarized in Table 5. The ultrasonic device measures actual wet gas velocity at the conditions noted. These conditions are at the location of the device and are not the same as the tank top conditions. As noted previously,

12

moisture condensation was observed at most locations due to the prevailing winter weather conditions during the field measurements. The results represent the average values for the measurement period and relative standard deviations for each measurement are indicated.

Measurement durations at each location and the actual velocity measurements are noted in figures 5 through 12 for the eight pads where measurements were successfully completed. In the figures, any gaps in measurement are reflective of operational issues related to the flow measurement device and do not reflect tank venting conditions. In general, lower flow rates are rather wispy with considerable variability while higher flow rates are relatively steady with minor variability. Average values were determined for the entire time period that measurements were obtained for a tank vent.

4.2 VENT GAS ANALYSESOf the ten attempted flow measurements, eight successfully resulted in solution gas flow rates as presented in Table 6. The last column of the table indicates the expected presence of casing gas in the measured vent gas flow rate.

The tank vent flow rate at Pad 2-1 normally flows to a flare but was released to atmosphere for measurement purposes. However, the flow rate measured was above the maximum measurable limit of about 2000 dsm3/d. Comparing the estimated value to the expected value in Table 4 for pad confirms that the measured value was well below the actual rate.

Measurements at pads 2-1, 15-36, 5-32, 8-39, 9-21N, 9-15E and 10-12 were on tanks where excess casing gas was vented into the production tank. Measurements at pads 8-31E, 8-21 and 13-14S were on tanks that vented solution gas only.

The average solution gas GOR based on these three measurements was 1.45 m3/m3 based on total gas released divided by total oil production for the three wells. This value is approximately half of the solution gas GOR applied by Baytex when estimating solution gas production. For the remaining pads, where casing gas most likely was directed into the tank that were measured, the vent gas GOR value ranged from 10.1 to 285.1 m3/m3 and averaged 51.1 m3/m3. This average is based on the sum of the measure flow rates divided by the total oil production for the pads included in these measurements. The average of 51.1 m3/m3 is higher than the average of 31.4 m3/m3calculated for the same production pads using the appropriate data from Table 4.

4.3 VENT GAS COMPOSITIONGas vented from production tanks was sampled at ten locations and of these gas directed to flare was sampled at two locations during the February 2013 field study. Based on operations at each location the samples were allocated to one of three categories: Casing and Solution Gas Mix, Solution Gas and Mixed Gas to Flare or Incinerator. Two tank vent locations (Pad 10-12 and Pad 8-31W) were sampled in July 2012 and these results were included in the Casing and Solution Gas Mix category. All samples were analyzed by AITF.

The air-free average composition profiles, RSD and number of samples in each category of the gas vented to atmosphere or directed to a flared or incinerator are presented Table 7. These averages are based on detailed multi-sample results provided in Appendix A. Table 23 is for mixed casing and solution gas vented to atmosphere, Table 24 is for solution gas vented to atmosphere and Table 25 is for mixed gas directed to a flare or an incinerator. The amount of air in the vented gas was calculated by removing all oxygen and the associated nitrogen from the laboratory report and is included in the first row of each analysis. The quantity of air varies considerably and is related to the actual production rates and related activities at each facility.

4.4 SITE SPECIFIC EMISSION FACTORS Three fuel and flue gas sample pairs were used to characterize the lift pump engines, compressor engines and fired tank heaters performance and develop site specific emission factors. The results for these three combustion devices are summarized in the following sections.

4.4.1 LIFT PUMP ENGINES Engines drive the hydraulic fluid pumps that operate the oil lift pumps. Combustion performance and emission factor development is based on fuel and flue gas samples collected at Pad 2-1. The discharge locations for these engines include ground level with horizontal directionality, above metal building compressor enclosure and above open area engine units as indicated in Figure 14 and Figure 15.

Figure 14. Lift pump engine located in a sheet metal building with a roof top emission discharge point.

25

Figure 15. Lift pump engine located in in the open showing emission discharge point. The results for fixed gases, volatiles and reduced sulphur compounds are presented in Table 8. Fuel and flue gas analyses are based on laboratory analyses of samples collected at Pad 2-1. Emission factors are based on material balance calculations of all compounds. The lift pump engine was determined to be operating at an air-to-fuel ratio of 10.6 based on a measured O2 of 2.996% (dry basis lab result). The calculated combustion efficiency of the lift pump engine was 99% and residual THC in the flue gases totaled 971.5 ppmv.

4.4.2 COMPRESSOR ENGINES Engines drive the compressors used to compress excess casing gas and deliver it into the gas gathering system. Combustion performance and emission factor development is based on fuel and flue gas samples collected at Pad 13-14. The discharge location for these engines is approximately 4 m above grade with a vertically up directionality as shown in Figure 16.

Figure 16. Typical casing gas compressor engine discharge located above sheet metal

building with flue gas sampling equipment shown. The results for fixed gases, volatiles and reduced sulphur compounds are presented in Table 9. Fuel and flue gas analyses are based on laboratory analyses of samples collected at Pad 13-14. Emission factors are based on material balance calculations of all compounds. The compressor engine was determined to be operating at an air-to-fuel ratio of 11.4 based on a measured O2 of 5.76% (dry basis lab result). The calculated combustion efficiency of the compressor engine was 98.4% and residual THC in the flue gases totaled 1,390.5 ppmv. The compressor at the gas plant located at 10-22-79-20W5 was assigned the same emission factors.

4.4.3 FIRED TANK HEATERSCombustion performance and emission factor development for the gas fired tank heaters is based on fuel and flue gas samples collected at Pad 5-32. The flue gas stack discharge point was about 1 meter above the 9.75 meter high production tanks as shown in Figure 17.

Figure 17. Typical production tanks showing fired heater stack.

The results for fixed gases, volatiles and reduced sulphur compounds are presented in Table 10.Fuel and flue gas analyses are based on laboratory analyses of samples collected at Pad 5-32.Emission factors are based on material balance calculations of all compounds. The tank heater was determined to be operating at an air-to-fuel ratio of 13.4 based on a measured O2 of 6.83% (dry basis Lab result). The calculated combustion efficiency of the tank heater was 99.99% and residual THC in the flue gases totaled 11.0 ppmv.

4.5 NOX, CO AND PM2.5 EMISSIONSEstimated emissions of NOx, CO and PM2.5 from combustion sources located at each production pad are based on applicable USEPA AP-42 emission factors as presented in Table 11 (USEPA).

4.6 SEMI-VOLATILE SUBSTANCESNumerous semi-volatile substances were identified and quantified. For each emission source the applicable average emission factor was determined and applied in the development of the Reno Field emission inventory.

4.6.1 TANK EMISSIONSSemi-volatile compounds were measured at three locations, Pad 2-1 and Pad 5-32 where the vented gas included casing and solution gas and Pad 13-14S where the vented gas was solution gas. The results of these analyses are presented in Table 12. The concentration of semi-volatile compounds in the vented solution gas (Pad 13-14) is much higher than in the vented mixed casing and solution gas (Pad 2-1 and 5-32). This was expected as the solution gas is produced with and

38

released from the heated oil while the casing gas is produced separately and not intimately comingled with the produced oil. However, the actual vent rate of solution gas was less than the actual vent rate of casing gas in those cases where the two gases are vented from the same tank.As a result the mixed gas semi-volatile compound concentrations are observed to be lower.

4.6.2 ENGINE EMISSIONSThe flue gases of three compressor engines were sampled for semi-volatiles and the results are presented in Table 13. The average emission factor was applied to all lift pump and compressor engines operating in the Baytex Reno Field. Because of the measured high combustion efficiency measured for the tank heater, no semi-volatile emission factors were applied to any of the heaters.

4.7 ODOUR SAMPLESClearstone collected tank vent gas samples in Tedlar bags for odour studies completed by RWDI. All samples were collected using a sample train consisting of a sample tube, a hand operated aspirator and a discharge tube connecting to the Tedlar bag. The sample tube was inserted directly into the tank vent. Due to the high moisture content of the vent gases, moisture condensation occurred in the sample line and aspirator. Immediately upon collection of each sample they were transferred to RWDI for labeling and custody. Two samples were collected for each of four tanks as listed in Table 14.

5 INVENTORY DEVELOPMENTThe Baytex Reno Field emission inventory is based on February 2013 production and related activities. Monthly flow rates of solution and casing gas are presented as daily averages. Similarly, fuel, vent to atmosphere, flare and incinerator gas flow rates are presented as daily averages but derived from the monthly production data.

Fuel gas, flue gases, tank vent to flare or incinerator, and tank vent to atmosphere compositions are based on field studies in July 2012 and February/March 2013, and as reported in Section 4.

5.1 COMBUSTION DEVICE EMISSIONSEmissions were compiled for all combustion devices at all production pads, the water injection facility and the gas plant. All emissions are based on fuel consumption and applicable site specific emission factors.

5.1.1 FUEL FLOW RATESCasing gas produced at a pad is used as fuel for the lift pump engines, compressor engines and tank heaters. Fuel consumption is based on information provided by Baytex and is summarized by well, pad and device in Table 15. In the case of burner fuel the value is the total for all tanks associated with a production well. Compressor fuel is more accurately reflective as pad activity and not specific well activity. Compressor fuel rate of zero indicates no compressor at location.

5.4 ODOUR SAMPLE RESULTSOdour sample results were provided by RWDI for processing and presentation in odour units per dry standard cubic meter of air free vent gas. This restatement of the odour units was required because the odour panel was exposed to diluted volumes of the sampled gas which contained various amounts of air in addition to the solution gas or mixed casing and solution gas and the estimated emission flow rate for each tank was based on a dry, air free gas to oil ratio.

The odour samples were collected on two types of venting situations. As noted in Table 22,samples collected at pads 08-21 and 13-14S were from tanks with solution gas and those at pads 05-32 and 02-01 were from tanks with mixed casing gas and solution gas. The samples from the two types of vented gas were analyzed separately to determine average and maximum odour strengths.

Expressing odour strength in terms of dry, air free vented gas required corrections for moisture and air in the sampled vapour. All samples were handled at room temperature and not heated prior to exposure to the odour panel. Therefore, the moisture content of the actual sample transferred to the odour panel sample dilution system was estimated to be 2.46%, the saturated

moisture content of air at 20 ºC and 94.8 kPa. The air content of the odour sample was not determined. However, samples were collected from the same tanks on days after the odour samples were collected and the air content was determined. The dates of the subsequent samples are noted in the table. Application of the air faction in samples results to restate the odour results is not without noteworthy uncertainty. Application requires the assumption that operations are relatively consistent and that the cycle of tank filling and product removal tanks was similar on both sample days. Notwithstanding this uncertainty, odour strength was restated based on the air fraction results determined on the days indicated in the table.

Solution gas was determined to have an odour strength ranging from 21,107 to 86,471 OU/dsm3

(air free). The average of 54,176 and maximum of 86,471 OU//dsm3 (air free) were applied to all wells in Table 19 that are noted to be venting solution gas.

Mixed casing and solution gas was determined to have an odour strength ranging from 3,611 to 9,069 OU/dsm3 (air free). The average of 6,247 and maximum of 9,069 OU//dsm3 (air free) were applied to all wells in Table 19 that are noted to be venting mixed casing and solution gas.

Based on the above, odour emissions for each well were estimated by multiplying oil production times the applied GOR times the applicable odour strength.

5.5 EMISSION INVENTORY DATA FILEGas composition and combustion equipment performance measurements specific to the Baytex Reno Field were used to develop applicable emission factors for all emission sources. The development of these emission factors is discussed in Section 4.4. The developed emission factors were used to create an emissions data file that is source specific and suitable for air quality assessments. The data file is referenced as Baytex Reno Field Emission Inventory February 2013_June 252013.xlsx. (Baytex Data 2013)

6 CONCLUSIONS

An emissions inventory of the Baytex Reno Field was completed based on field measurements to assess and characterize combustion source and production tank emissions. The inventory included all 23 production pads with 41 production wells, the water injection or disposal well and the gas plant. Two pads including four well are noted to be shut in and zero emissions were assigned to these pads.

Field measurements included sampling and analyzing casing and solution gas and mixtures of the two as released from tank vents. Measurements were conducted at ten different pads in 2013. In 2012, two pads were sampled and analyzed using the same methodology and these results are used in the development of the inventory. Tank vent gas flow rates were measure and corrected to dry, air-free flow rates for purposes of calculating vent gas to oil ratios and field emissions.

Lift pump and compressor engines and tank heaters were tested for combustion efficiency and residual emissions. These assessments included fuel and flue gas sampling and analyses and the completion of multi-component material balances to determine site specific combustion efficiencies, air to fuel ratios and emission factors. Over 160 compounds were identified, quantified and included in this assessment. The applicable calculated emission factors were applied to all combustion sources. Published emission factors for NOx, CO and PM2.5, were applied to all engine, heater, flare and incinerator emission sources.

In addition, semi-volatile compound sampling was completed for compressor engines and for tank vents. The analytical protocol included the quantification of 40 different compounds in this category. Results were converted to appropriate emissions factors for engine and tank emissions sources and applied in the development of the inventory.

Samples of vent gases were collected for odour determination by RWDI. The raw data was provided to Clearstone and the results were processed to express the odour strength of each sample on a dry air-free basis.

The Reno Field emission inventory developed for air quality modeling by RWDI was based on the flue and vent gas emission profiles determined by Clearstone, calculated fuel consumption for each combustion device using February 2013 average daily production data provided by Baytex and an average GOR of 51 dm3 air-free vent gas per m3 of oil production specified by Baytex. This GOR compares favourably with the average GOR of the production locations tested by Clearstone where the vent gas included casing and solution gas. The value would be considered high for those locations where solution gas only was vented form the production tanks.

The developed emission factors were expressed as mass emission per cubic meter of fuel consumed for combustion devices and mass emission per cubic meter of dry air-free vented gas.The complete emission inventory includes source specific emissions for each point source type at each location. All emissions were expressed in grams per second. Supporting tables relevant to

59

the development of the emissions inventory are included in this report and the inventory is compiled in a data file (Baytex Reno 2013) for application in air dispersion modeling.
