3 EXECUTIVE SUMMARY Howe Gastmeier Chapnik Limited ( HGC Engineering ) was retained by wpd Canada Corporation ( wpd Canada ) to assess the acoustic impact of the proposed White Pines Wind Project. The proposed wind project site is located in the wards of South Marysburgh and Athol in Prince Edward County, Ontario. This assessment considers twenty-seven REpower MM92 wind turbine generators, each rated at 2.05 MW. HGC Engineering has assessed the acoustic impact against the acoustic criteria of the Ontario Ministry of the Environment ( MOE ) and in accordance with the requirements of Ontario Regulation 359/09. This report comprises a summary of our assessment and is intended as supporting documentation for an application for a Renewable Energy Approval. There are a number of residences located in the vicinity of the project. From an acoustic perspective, the area is a rural environment, with relatively low ambient sound levels. The criteria of MOE publication Noise Guidelines for Wind Farms Interpretation for Applying MOE NPC Technical Publications to Wind Power Generation Facilities is applicable. The sound power data for the REpower wind turbine generators has been obtained through wpd Canada. This data has been used in a computer model to predict the sound level impact at the closest residential receptors. The results of the modelling demonstrate compliance with the MOE guidelines when all twenty-seven turbines are operating over their entire speed range, at all but three receptor locations. These receptor locations have entered into lease agreements with the proponent. Details of our assessment are provided in the main body of this report. The report is structured around the report format suggested by the MOE for Renewable Energy Approval applications for wind projects, with the required summary tables included as Appendix A. iii

The purpose of the report is to determine the acceptability of the predicted sound levels at the nearby residential receptors resulting from the operation of twenty-seven, 100 meter hub height, REpower MM92 wind turbine generators, rated at 2.05 MW, in relation to the guidelines of the Ontario Ministry of the Environment ( MOE ) including Ontario Regulation 359/09. Based on Ontario Regulation 359/09, the Project is considered a Class 4 wind facility. This report is intended as supporting documentation for a Renewable Energy Approval application for the facility. UPDATES ADDRESSED IN THIS ASSESSMENT REPORT This update has been prepared to address the removal of wind turbines WTG07 and WTG11 from the project. Participating receptors PR02 and PR16 are no longer participating receptors and have been relabelled to R452 and R453, respectively. Version 5 of the Noise Assessment Report included a number of clarifications of receptor coordinates identified through recent aerial imagery, field reconnaissance and feedback from local landowners and the MOE. Table 1 provides a comparison of the receptor coordinates. Version 4 of Noise Assessment Report included revisions to the location of TS1. Version 3 included revisions to address incorrect labelling of TS2 on Figure 3, add UTM coordinates for the TS2 acoustic barrier, clarify the number of total receptors, include a receptor concordance table and to update transformer sound levels and locations. Version 2 of the report included the relocation/renaming of 33 receptors.

7 wpd Canada Corporation Page 7 White Pines Wind Project, Noise Assessment Report May 4, GENERAL DESCRIPTION OF WIND TURBINE INSTALLATION SITE AND SURROUNDING ENVIRONMENT The wind project consists of twenty-seven wind turbine generators to be located in the wards of South Marysburgh and Athol, within Prince Edward County, as shown in Figure 1. The eastern portion of the wind power project is bound by Regional Road 13 to the north and east, Gravelly Bay Road to the south and Ostrander Point Road to the west. The western portion of the wind project is bound by Regional Road 17 and Bond Road to the north, Helmer Road to the east, Lake Ontario to the south and Lighthall Road to the west. The area is rural in nature, both acoustically and in general character, with agricultural land uses widely in evidence, including scattered dwellings near the major roadways. Zoning maps obtained from Prince Edward County are included as Appendix B, which illustrate that the project site areas are zoned for Rural use, and that small residential parcels, generally with Rural Residential zoning, exist around the lands. There is one adjacent wind project, the Ostrander Point Wind Energy Park, which is located between the two portions of the White Pines Wind Project, as shown in Figure 1. The Ostrander Point Wind Energy Park consists of one transformer and nine GE 2.5xl 2.5MW wind turbines with 100 meter rotor diameters and 85 meter hub heights. Due to the proximity of the Ostrander Point wind project (within 5 km of an identified receptor), cumulative sound levels are considered in this assessment. 3 DESCRIPTION OF SOUND SOURCES Twenty-seven 2.05 MW REpower MM92 wind turbine generators are proposed for the site. They are three bladed, upwind, horizontal axis wind turbines with a rotor diameter of 92.5 meters. The turbine rotor and nacelle are mounted on top of a 100 meter high tubular tower. The turbines are anticipated to operate continuously whenever wind conditions allow. Additional details are contained in Appendix C, with acoustic information contained in Appendix D. Electronic topography mapping for the area suggests that the turbines will generally be based at an elevation of between 70 and 105 meters. Table 2 provides the UTM coordinates (Zone 18) of the twenty-seven wind turbine generators and the two proposed transformers.

Additional details regarding the larger step-up transformers are provided in Section 5, below. 4 WIND TURBINE NOISE EMISSION RATINGS Overall sound power data for the REpower MM92 wind turbines as determined in accordance with IEC :2002+A1:2006 [1], are provided by REpower Systems in the document Power Curve & Sound Power Level REpower MM92 [2050 kw] [2] (herein called the Acoustic Report ) included in Appendix D. Additionally, a test report completed by windtest, Acoustic report for a wind turbine type REpower MM92 at Chemin d Ablis / France, operation mode 2050 kw [3], is also included under Appendix D. CAN/CSA C standard, referenced by the MOE, is an adoption without modification of the identically titled IEC Standard IEC (edition 2:2002

9 wpd Canada Corporation Page 9 White Pines Wind Project, Noise Assessment Report May 4, 2015 consolidated with amendment 1:2006). The overall A-weighted sound power levels as a function of 10 meter height wind speed are shown in Table 3. Table 3: 10 Meter Height Wind Speed vs Turbine Sound Power Level, Based on IEC Sound Power Determination Methodology and Wind Shear of 0.2 Wind Speed [m/s] at 10m Height Wind Turbine Sound Power Level [dba] Sound power level data determined under IEC is normalized to a standard roughness length value of 0.05 m. The roughness length concept is used to take into account the effect of friction at the ground, which results in lower wind speeds near the ground than at higher elevations. The wind shear exponent quantifies the same concept by describing the rate of change of windspeed with elevation. A roughness length of 0.05 m is generally held to be equivalent to a wind shear value of about 0.2. Meteorological data near the proposed wind project provided by wpd Canada indicates that the wind shear coefficient during a summer night may reach 0.49 (Appendix G). This means that a 10 meter height wind speed of 2.3 m/s can occur simultaneously with a 7 m/s wind speed at the hub height of 100 meters, indicating that maximum sound power output may occur during relatively low 10 meter level wind speeds. Consequently the maximum sound power level for the wind turbine (corresponding to a hub height wind speed of 7 m/s) has been used in this analysis. Table 4 presents the typical octave band spectrum for various 10 m height wind speeds received from REpower, also included in Appendix D. The spectral shape shown for the 10 m height 7 m/s wind speed has been used in the analysis.

A tonal penalty has not been applied in this assessment. Additionally, the Acoustic Report indicates that the maximum sound power level of dba includes a measurement uncertainty of approximately 1 db. The sound level predictions herein are subject to the degree of uncertainty related to the sound power of the turbine, in addition to the uncertainty related to the fluctuations of atmospheric conditions and the accuracy and limitations inherent in the modelling methodology. 5 TRANSFORMER SOUND POWER ESTIMATION The project proposes to utilize two 65 MVA transformers. One transformer (TS1) will be located approximately 15 km north of the project, north of the Town of Picton. The second transformer (TS2) will be located approximately 1400 meters south of WTG05. Both transformers have been included under this Noise Assessment.

11 wpd Canada Corporation Page 11 White Pines Wind Project, Noise Assessment Report May 4, 2015 The south transformer station (TS2) is proposed to include a 5.5 meter high acoustic barrier on the north and east sides of the transformer. The proposed barrier is shown in Figure 3 and is proposed to be constructed at the following UTM coordinates: Table 5: Proposed Transformer Acoustic Barrier Coordinates [m] Point Easting Northing Northwest Northeast Southeast Acoustic barriers can be effectively constructed out of a wide variety of materials and can be styled in many ways, provided that it is dense, and is free of gaps or cracks within or below its extent. The MOE recommends that regardless of material, the surface density of a noise barrier wall should be at least 20 kg/m 2. The acoustic barrier will be absorptive with a minimum Noise Reduction Coefficient ( NRC ) of The transformers are proposed to be General Electric 39/52/65 MVA transformers which will have maximum National Electrical Manufacturers Association ( NEMA ) sound level of 71 db measured in accordance with IEEE Standard C , IEEE Standard Test Code for Liquid-Immersed Distribution, Power and Regulating Transformers [4]. Using the drawings provided in Appendix E, an enclosing surface area estimate of 266 m 2 was determined. The NEMA sound rating and the measurement surface area were used to compute the overall sound power level of 95.6 dba [5]. Under MOE guidelines tonal noises, such as the hum typically produced by electrical transformers, are penalized 5 dba to account for the increased potential for annoyance that such sounds tend to have [6]. This assessment considers two transformers, each with a maximum sound power level of 101 dba re W, including the 5 dba tonal penalty. Calculation details are included in Appendix E.

12 wpd Canada Corporation Page 12 White Pines Wind Project, Noise Assessment Report May 4, POINT OF RECEPTION SUMMARY As shown in Figures 2a and 2b, there are several residences in the vicinity of the project, generally sited along the major roadways. Receptor locations were identified by wpd Canada and their consultants through aerial imagery, building permit requests, land parcel mapping, field reconnaissance, and discussions with local land owners. A table of UTM coordinates for 670 receptors, including vacant lots, located near the proposed wind turbine generators was received from wpd Canada. Based on information received from wpd Canada and their consultants, 327 nonparticipating receptors, 154 vacant lot receptors and 18 participating receptors are located within 1500 meters of a proposed wind turbine or within 1000 meters of a proposed transformer and sound level predictions are provided for these locations herein. The existing receptors and vacant lots, together with their coordinates are listed in Tables A3 and A4. A concordance table identifying the common receptors between the wpd White Pines Wind Project and the Gilead Ostrander Point Wind Project is attached as Table 6. For the purposes of this report, each of the 499 receptors was represented by a discrete sound prediction location at the dwelling coordinate, with an assumed height of 4.5 meters above the local grade to represent potential second-story windows. Where vacant lots were identified, the assumed future location of the dwelling was selected to be consistent with the typical building pattern in the area as per Section 1(4) of Ontario Regulation 359/09. wpd Canada has indicated all receptors within the study area are two storey s or less. A number of the receptors have agreements with wpd Canada. These receptors are identified as participating receptors by the MOE. According to the MOE publication Noise Guidelines for Wind Farms Interpretation for Applying MOE NPC Publications to Wind Power Generation Facilities, October 2008 ( Interpretation ) [7], a participating receptor means a property that is associated with the Wind Project by means of a legal agreement with the property owner for the installation and operation of wind turbines or related equipment located on that property. According to Ontario Regulation 195/12, Section 1 (4) a noise receptor does not include a location on a parcel of land if any part of the renewable energy generation facility will be located on that parcel of land once the facility is installed, constructed or expanded in accordance with the renewable energy approval. [8]

13 wpd Canada Corporation Page 13 White Pines Wind Project, Noise Assessment Report May 4, 2015 Figure 4 shows the wind project infrastructure on the various participating lots. Table A3 includes the non-participating receptors while Table A4 includes the details of the participating receptors. 7 ASSESSMENT CRITERIA The MOE publication Noise Guidelines for Wind Farms Interpretation for Applying MOE NPC Publications to Wind Power Generation Facilities provides sound level criteria for wind power projects. Because wind turbines generate more sound as the wind speeds increase, and because increasing wind speeds tend to cause greater background sound levels, wind turbine generators have been identified by the MOE as a unique case in comparison to other stationary noise sources. The sound level criteria for wind turbines are provided as a function of 10 meter height wind speed. The criteria are presented in A-weighted decibels in Table 7. Table 7: Wind Turbine Noise Criteria [dba] Wind Speed (m/s) at 10 m Height Sound Level Limits [dba] It should be noted that the MOE guidelines, including Interpretation do not require or imply that a noise source should be inaudible at a point of reception, and inaudibility should not be expected. In fact, even when the sound levels from a source are less than the numeric guideline limits, spectral and temporal characteristics of a sound regularly result in audibility at points of reception. To be clear, wind turbines will be audible at many residences even when sound levels are below MOE noise criteria guidelines. In the case of this assessment, the sound power output of the REpower MM92 wind turbines is assumed to be constant at the maximum value of dba over the full range of 10 meter height wind speeds due to the average summer nighttime wind shear exponent, which means that strong hub height winds and the maximum sound power level can occur at the same time as low 10 meter height winds and low background sound. Thus, the assessment of the REpower wind turbines is based on the minimum criteria of 40 dba and the maximum wind turbine sound power level.

14 wpd Canada Corporation Page 14 White Pines Wind Project, Noise Assessment Report May 4, IMPACT ASSESSMENT An acoustic model of the site was created on a computer using Cadna/A (version ), a commercial acoustic modeling system. Cadna/A uses the computational procedures of ISO , Acoustics Attenuation of sound during propagation outdoors Part 2: General method of calculation [9], which accounts for the reduction in sound level with distance due to geometrical spreading, air absorption, ground attenuation and acoustical shielding by intervening structures (or by topography and foliage where applicable). This is the standard that is specified by Interpretation to be used in the assessment of wind power project noise. Topographical data for the site and surrounding area was provided by wpd Canada. Ground attenuation was assumed to be spectral for all sources, with the ground factor (G) assumed to be 0.7 globally. The temperature and relative humidity were assumed to be 10 C and 70%, respectively. Stands of foliage were not modelled. For each receptor the predictions include the sound emissions of known wind turbines within a 5 km radius as stipulated in the 2008 MOE Interpretation. Details for the Gilead Power Ostrander Point Wind Energy Park were obtained from the Design and Operations Report, dated May 2011 [10] and the Noise Impact Assessment, dated July 2010 [11]. The wind turbine and transformer locations, as well as their sound power levels were obtained from the above reports and are included under Appendix A of this report. All wind turbine generators for the White Pines project were modeled as point sources at a height of 100 meters above grade. For the Ostrander Point project the wind turbines were modeled as point sources at a height of 85 meters above grade. Figure 2 presents the acoustic model, with the source and receptor locations shown. Figure 5 shows the sound contour map of the area surrounding the facility produced by Cadna/A based on the octave band power levels corresponding to the overall dba sound power level for each REpower wind turbine. The required summary tables are contained in Appendix A of this report. In accordance with the 2008 MOE Interpretation, sound level predictions for receptors within 1500 meters of the proposed wind turbines and 1000 meters of the proposed transformers are presented in Tables A4 through A10. In general, sound levels are predicted to be at or below the

15 wpd Canada Corporation Page 15 White Pines Wind Project, Noise Assessment Report May 4, dba minimum criterion at all but three participating receptor locations. At these participating receptors sound levels of up to 40.7 dba are predicted. The owners of these properties have entered into lease agreements with the proponent and include a wind turbine or related infrastructure on the properties. These receptors are considered herein to be part of the project (ie. participating receptors) and not sensitive receptors for the purposes of sound level impact. Details of the calculations are provided in Appendix F. When conducting an acoustic audit of a conventional stationary industrial sound source, the MOE guidelines direct that periods of high wind be excluded. Typically, the noise output of industrial sound sources is independent of wind speed. However, this is not the case for wind plants and there is an intrinsic relationship between wind speed (and therefore ambient noise) and increased sound power levels associated with the wind turbine generators. Complicating matters, there is a large degree of variability related to environmental factors within the wind plant area including, among others, local ground level wind speeds, wind speeds affecting the wind turbine generator blades, the associated wind shear, and the sound power of the wind turbine generators, all of which affect the measured sound levels. Thus, it is not realistic to expect that in practice a single repeatable sound level can or will be measured for a given wind speed at a given setback distance; a simple comparison of single numbers is not sufficient or possible. 9 CONCLUSIONS The analysis, performed in accordance with the methods prescribed by the Ontario Ministry of the Environment in publication Interpretation for Applying MOE NPC Publications to Wind Power Generation Facilities, October 2008, indicates that the operation of the proposed wind project will comply with the requirements of MOE publication Noise Guidelines for Wind Farms, Interpretation for Applying MOE NPC Publications to Wind Power Generation Facilities for all identified nonparticipating receptor locations.
