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.

1 INTRODUCTION 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

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.


2 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.

Smaller transformers will be installed at each of the wind turbine generator locations however these

are acoustically insignificant in comparison to the wind turbine generator sound power levels. Two

large step-up transformers will be installed as part of the project. 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 61400-11:2002+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 C61400-11-07 standard, referenced by the MOE, is an adoption

without modification of the identically titled IEC Standard IEC 61400-11 (edition 2:2002


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 6 7 8 9 10

Wind Turbine 103.4 104.2 104.2 104.2 104.2

Sound Power Level [dBA]

Sound power level data determined under IEC 61400-11 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.

The Acoustic Report indicates REpower warrants that there is no tonal audibility greater than 0 dB.

A tonal penalty has not been applied in this assessment. Additionally, the Acoustic Report indicates

that the maximum sound power level of 104.2 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.


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 332904 4862992

Northeast 332912 4862997

Southeast 332917 4862989

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/m2. The acoustic barrier will be absorptive with a minimum Noise Reduction Coefficient

(“NRC”) of 0.85.

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 C57.12.90, “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 m2 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 10-12 W, including the 5 dBA tonal penalty. Calculation details are included in

Appendix E.


6 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 non-

participating 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]


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

4 5 6 7 8 9 10

Sound Level Limits [dBA] 40.0 40.0 40.0 43.0 45.0 49.0 51.0

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 104.2 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.


8 IMPACT ASSESSMENT

An acoustic model of the site was created on a computer using Cadna/A (version 4.4.145), a

commercial acoustic modeling system. Cadna/A uses the computational procedures of ISO 9613-2,

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

104.2 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


40.0 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 non-

participating receptor locations.
