    2019 Annual Report for Authorization 8808 - Atlantic Power - Williams Lake Power Plant Executive Summary This Report details the Environmental Emissions from January 1, 2019 to December 31, 2019 and fulfils the requirement of section 3.6 of Authorization 8808 [1]. No rail ties or greater than 1% construction and demolition (C&D) waste were used as feedstock during the reporting period. A total of 240,218 wet tonnes of clean biomass was incinerated during 3283 hours of normal operation. During this time two discrete monitoring sessions (one for Air Discharge from the Stack and one for Ash Analysis) were performed. The test results were compared against the levels in Permit 8808 and the Hazardous Waste Regulation, and no exceedances of any of the parameters in Schedules A and D of the Permit measured. Continuous Emissions Monitoring System (CEMS) measurements were also taken as required by the Permit throughout this Period, with no exceedances recorded. Respectfully, Jacob Steyl, P.Eng January 13, 2020 i

    2019 Annual Report for Authorization 8808 - Atlantic Power - Williams Lake Power Plant 1 Introduction An amendment was issued for permit 8808 on 18 September 2019 to Atlantic Power Preferred Equity Ltd located at 4455 Mackenzie Ave N, Williams Lake, B.C., V2G 4R7. The revised permit calls for an Annual Report outlined in Section 3.6 of the Permit [1]. Jacob Steyl P.Eng, Maintenance Manager and Chris Turner, Controls Specialist were responsible for collecting data and compiling this report. A. Lanfranco & Associates Inc. and Bureau Veritas conducted discrete monitoring outlined in sections 3.1.2 Schedule A and 3.1.3 Schedule D of the Permit [1]. The reporting window for this Report is 00:00 on 1 January 2019 to 00:00 1 January 2020. The Plant was curtailed for extended periods during the year, as show in Figure 1-1 and Table 2-1. Figure 1-1: Normal Operating time for 2019 As no rail tie material was used as feedstock during the reporting period – Test Regimes Schedule A and D apply. Corrective and preventative maintenance, as well as calibrations, were performed on the Air Emissions Controls and Continuous Emissions Monitoring System (CEMS) equipment of the Authorized Works during the reporting period. 1

    2019 Annual Report for Authorization 8808 - Atlantic Power - Williams Lake Power Plant 4 Continuous Emissions Monitoring 4.1 Sulphur Oxides No rail ties or greater than 1% C&D waste was used as feedstock during the reporting period, therefore no monitoring for Sulphur Oxides was required or conducted. 4.2 Nitrogen Oxides The maximum hourly Nitrogen Oxides (NOₓ) as Nitrogen Dioxide (NO₂) per month and average for the month at 8% O₂ is show Table 4-1. The Permitted hourly average is 320 mg/m³ at 8% O₂ [1]. Table 4-1: Maximum hourly NOx as NO2 per month and average for the Month Maximum Hourly Average Monthly Average mg/m³ mg/m³ Jan-19 251 217 Feb-19 245 219 Mar-19 244 219 Apr-19 239 222 May-19 249 224 Jun-19 - - Jul-19 - - Aug-19 251 233 Sep-19 245 229 Oct-19 - - Nov-19 - - Dec-19 242 210 The average NOx emissions for the year was 222 mg/m³ at 8% O₂. The maximum hourly average for the year is well below the Permitted level. 4.3 Hydrochloric Acid No rail ties or greater than 1% C&D waste were used as feedstock during the reporting period, therefore no monitoring for Hydrochloric Acid was required or conducted. 4.4 Combustion Temperature No rail ties or greater than 1% C&D waste were used as feedstock during the reporting period, therefore no monitoring of Combustion Temperature was required or conducted. 3

    2019 Annual Report for Authorization 8808 - Atlantic Power - Williams Lake Power Plant 5 Discrete Monitoring 5.1 Air Emissions Stack Test No rail ties or greater than 1% C&D waste were used as feedstock during the reporting period: Only Schedule A applies. The permitted levels under Schedule A [1] is stated in Table 5-1. A. Lanfranco & Associates Inc was retained to perform an Emission Compliance Survey and Monitoring Report, as per Schedule A of the Permit. The Triplicate test average results for the listed parameters for the Main Stack on September 19, 2019 are summarised in Table 5-1. The complete report can be found in Appendix A – Stack Particulate Test. Table 5-1: Schedule A Discrete Monitoring Results Parameter Test Average Permit Limits Rate of Discharge (m³/s) 96.8 110 Particulate (mg/m³ @ 8% O₂) 2.0 20 Both parameters measure are below permitted levels. The average steam flow during the Stack Test on Sep 19 was 593.5 klb/hr (74.8 kg/s). This is 99% of the 90th percentile for the last 100 operating days and 108% of the average steam flow for the last 30 full operating days before the date of the test. The dates used for the last 100 operating days (shown in Figure 5-1) was 27 Jan 2019 to 11 Mar 2019, 15 Apr 2019 to 04 May 2019 and 12 Aug 2019 to 19 Sep 2019. The dates used for the last 30 full operating days was 20 Aug 2019 thru 19 Sep 2019. 4

    2019 Annual Report for Authorization 8808 - Atlantic Power - Williams Lake Power Plant 5.2 Ash Testing No rail ties or greater than 1% C&D waste were used as feedstock during the reporting period: Only Schedule D applies. The permitted levels as per Schedule D [1] is stated in Table 5-2. Bureau Veritas was commissioned to perform ash analysis on a single ash sample collected before ash conditioning during normal operation. The ash sample was collected on 19 September 2019 under the same conditions as the stack test was conducted. The results from the test is summarised in Table 5-2. The complete reports can be found in Appendix B - Ash Analysis . Table 5-2: Schedule D Discrete Monitoring Results Parameter Average Permitted Limits [2] Arsenic (mg/L) <0.10 2.5 Barium (mg/L) 1.45 100 Boron (mg/L) 2.62 500 Cadmium (mg/L) <0.10 0.5 Chromium (mg/L) <0.10 5 Copper (mg/L) <0.10 100 Lead (mg/L) <0.10 5 Mercury (mg/L) <0.0020 0.1 Selenium (mg/L) <0.10 1 Silver (mg/L) <0.010 5 Uranium (mg/L) <0.10 10 Zinc (mg/L) <0.10 500 Dioxin/Furan TEQ (ppb) 0.06630 100 Polycyclic Aromatic Hydrocarbon TEQ (ppm) 0.026 100 All the parameters measured were well below the values stipulated in the Hazardous Waste Regulation [2]. 5
