Greetings,

Included in this package are electronic copies of the Environmental Noise Impact Reports for the

CAW Clean Wind Energy Project. The enclosed report provides the results of noise modeling for

the Enercon E48 turbine for constrained operation at 500kW, as it will be operated under the

existing FIT contract.

Our wind turbine has received a Noise Certificate of Approval from the Ministry of Environment

for unconstrained operation at 800kW. However, as noted, our union will be operating the wind

turbine at a constrained operation of 500kW.

Under constrained operation the maximum noise levels at surrounding receptors are lower than

those approved previously by the MOE as part of the application for the CofA.

This report expands upon the information provided to the Ministry of Environment on November

17, 2011 for the turbine under constrained operation at 500kW. At that time only the detailed

simulation results were provided; this report provides additional background explaining the

simulation methodology and results.

In the spirit of openness and transparency, I am happy to make these reports available to the

public. I will stress that all results crafted in these reports, as in any noise modeling assessments,

are based on estimates.

Over the coming months, our union will commission additional noise assessments that will draw

on actual noise data during the turbine’s operation. We will also make these assessments

available to the public.

I hope that this information proves useful to all those interested.

Sincerely,

Ken Lewenza

1 INTRODUCTION

MKI was retained by CAW to prepare an Environmental Noise Impact Assessment for the proposed Clean Wind Energy Project (the Project) in the Town of Saugeen Shores, Ontario. This assessment follows previous assessments which formed the basis of Noise Certificate of Approval (C of A) applications to the Ministry of the Environment (MOE). This assessment differs from previous assessments in the following ways:

1. It has been prepared for the Enercon E48 turbine constrained to 500 kW, rather than the Enercon E48 turbine unconstrained at 800 kW maximum output.

2. It uses a guaranteed maximum sound power level of 100.0 dB(A) plus a 1.0 dB(A) measurement uncertainty safety factor for a total of 101.0 dB(A) for the turbine at 500 kW, as opposed to the guaranteed maximum sound power level of 102.5 dB(A) plus a 1.0 dB(A) measurement uncertainty factor for a total of 103.5 dB(A) for the turbine at 800 kW.

3. It will not form a part of an application for a Noise C of A to the MOE. It is provided for information purposes only.

4. Appendices are limited to detailed noise simulation results and a zoning map which served as a source for establishing the original noise receptor information. Confidential noise specifications from Enercon have been specifically excluded as it is understood that the CAW intends to release the report to the public for information purposes.

In all other ways this report contains the same information and follows the same guidelines as previous reports used as the basis for Noise C of A applications.

This report:

a. Provides information on noise sources and receptors, including maps of the project area with the single turbine location, noise receptors, and noise contour lines for 10 m/s wind speed (worst case).

b. Outlines all critical points of reception and points of reception over 1 km away from the single wind turbine.

c. Outlines and defines the noise area classification of all points of reception.

d. Provides a summary table of calculated noise levels at all points of reception, as predicted by the required ISO 9613-2 (“Acoustics-Attenuation of sound during propagation outdoors”) method.



2 PROJECT LAYOUT

2.1 Project Location

The Canadian Auto Workers Union (CAW) is the largest private sector union in Canada. Since 1956, the CAW (then part of the UAW) has developed a Family Education Centre near Port Elgin, Ontario. The facility was modernized in 1988 and is now a year-round, 47-acre site capable of hosting conferences, summer camps, and indoor/outdoor recreational activities. The wind turbine proposed for the facility will generate a substantial amount of renewable energy and reduce the facility’s environmental impact. The location of the proposed wind turbine is outlined in Figure 1 and Figure 2, on the following pages.

The CAW Family Education Centre lies on the east shore of Lake Huron, roughly 500m southeast of the shoreline and 2 km southwest of downtown Port Elgin. The area is exposed to some of Ontario’s most energetic winds.

The potential turbine site is located within the eastern portion of the CAW Family Education Centre property, directly southwest of the 90 degree bend in the Ring Road. The property is situated within National Topographic System (NTS) 1:50,000 map sheet 30 M/5. Turbine co-ordinates are listed in Table 1.

Sports fields immediately surround the proposed turbine location from the north to the southeast. Agricultural fields lie beyond the CAW property boundary from the north clockwise through the southwest. A ‘big box’ commercial area is located roughly 800 metres to the east of the site along Highway 21. From the southwest clockwise to the north lies a small bluff, parallel to the shoreline and covered in mature-cedar, at a minimum distance of approximately 120 metres. Lake Huron lies roughly 350 metres beyond the bluff. CAW Road (Bruce County Road 25) runs northwest-southeast and is roughly 180 metres from the proposed turbine location at its closest approach. A small airfield lies approximately 1.1 km to the south of the proposed turbine location.

2.2 Zoning and Land Use

Land use in the area is quite diverse and includes institutional, agricultural, residential, commercial, cottage, recreational, and urban uses. A zoning map of the area is included in Appendix B. The land immediately north of the project site and clockwise to the south-east is zoned as “Planned Development.” These lands are either currently producing or out-of-production agricultural lands that are presently under construction for a housing development. The development plan is included in Appendix B and was used to locate future receptors in the noise assessment for the original Noise C of A application. An easement, approximately 30 m wide, borders the eastern boundary of the CAW property. To the south, immediately across CAW Road, lies a small, commercially-zoned area. “Detached Residential” zoning dominates the area from the south-west through to north.

2.3 Points of Reception (POR)

Points of reception (POR) surround the single turbine on all sides. POR’s greater than one kilometre away from the proposed turbine are outlined and defined in Section 4. The majority of POR’s are residences, seasonal cottages, or future residences. No seniors’ residences,



daycares, hospitals, or schools are known to be included amongst the receptors used in this analysis. UTM coordinates and elevations for all POR’s are presented in Section 4 and in Appendix A.

2.4 Topography

The topography surrounding the CAW Family Education Centre is generally flat, but slopes gently toward Lake Huron. As discussed in Section 2.1, there is a small bluff that runs parallel to the Lake Huron Shore. This bluff is approximately 5 to 10 metres in total height.

2.5 Transformer Location

The transformer for the single Enercon E48 will be located either inside the base of the tower. There is no transformer substation for this single turbine.

2.6 Other Wind Farms within Five Kilometres

Enbridge Ontario Wind Power L.P. operates the closest wind power project to the CAW Family Education Centre. The nearest turbine from this project is over 5 km away, in an adjacent municipality.

3 NOISE SOURCES

3.1 Wind Turbine Description

The selected wind turbine for the CAW Clean Wind Energy Project is the Enercon E48; an 800 kW, 3-bladed, horizontal axis, upwind turbine with a 48 m rotor diameter and a 76 m hub height. The turbine is being constrained to 500 kW operation under the existing Feed-in Tariff (FIT) Contract. The turbine is gearless in design and has a variable speed generator. The rotor is designed to operate between 16 - 30 rpm. The turbine location is detailed in Figure 2 and in Table 1.

Table 1: Wind Turbine Location

Project Name: CAW Clean Wind Energy Project Type of Coordinates: UTM NAD83, Zone 17

Identifier Make and Model Location Coordinates Ground Elevation (m) Easting Northing

1 Enercon E48 467355 4919406 195.8

3.2 Transformer Description

The transformer for the single Enercon E48 will be located inside the base of the tower. A specific make and model has yet to be defined. The transformer will be rated at approximately 1 MVA. The low voltage side of the transformer will be 400 V and the high voltage side will be 600 V.

The noise emission level from a transformer of this size does not make a significant contribution to the overall sound power level of the wind turbine. For this reason the transformer is not included as a noise source in the analysis contained in this report.

3.3 Guaranteed Sound Power Levels

The guaranteed sound power level data for the Enercon E48 was provided by Enercon Gmbh. Guaranteed maximum sound power levels were provided for a range of wind speeds for unconstrained operation at 800 kW, with a maximum of 102.5 dB(A) at wind speeds equal to and above 10 m/s wind speeds. For constrained operation at 500 kW only a single maximum sound power level of 100.0 dB(A) was provided. In order to produce a worst-case sound power level curve for constrained operation at 500 kW, the sound power level curve for unconstrained operation at 800 kW has effectively been capped at 100.0 dB(A), keeping all other sound power levels the same. On top of this, a 1.0 dB(A) safety factor was added to account for potential field instrument measurement inaccuracy. Table 2 details the guaranteed sound power levels provided by Enercon, and those used for noise calculations as a function of the wind speed at 10 m above ground level.

No modifications were made to the sound power levels based on wind shear considerations.

Maximum 102.5 100.0 1.0 101.0

3.4 Octave Band Data

The octave band data used in this analysis were generated by the WindPro 2.7 software used for wind farm design and noise calculations. The generated octave band data are typical based on turbine power output, rotor dimensions, and RPM and have no tonal quality (see Section 3.5). The generated octave values are shown in Appendix A.

3.5 Tonality

Tonality refers to higher levels of noise emitted from a narrow band of frequencies, experienced as a particular pitch or tone. Most modern turbines do not have a tonal quality to their noise emission that is significant enough to require a noise penalty.

The Enercon E48 noise specifications suggest that tonal penalties are not required according to IEC 61400-11:1998.

3.6 Impulsivity

Impulsivity refers to noise level periodicity, experienced as pulsating sound. No impulsive noise is created under foreseeable worst case scenario operating conditions of an Enercon E48.



4 RECEPTORS

4.1 Noise Receptors

The analysis in this report includes all critical POR’s surrounding the turbine on all sides, as well as additional POR’s beyond 1000 m from the proposed turbine. Figure 2 and Appendix A illustrate the POR locations in relation to the proposed turbine. POR distances from turbines are summarized in Table 3, included on the following page.

A list of residences, businesses, and future development surrounding the CAW Family Education Centre was obtained from Ontario Base Maps of the area, a developer’s website, and on-site visits to confirm the closest and most critical POR’s. Some POR’s have been represented as single “block” areas. This is intended to simplify the evaluation of a group of receptors while maintaining the evaluation’s full integrity. Predicted noise levels within these “block” areas correspond to the highest noise level within the area. “Block” area distances to the turbine correspond to the shortest distance from the area to the turbine. Co-ordinates listed for the “block” areas define the bounds of the area.

All single-storey, two-storey, and bungalow residences have been modeled as two-storey residences. POR height was defined as 4.5 metres above ground level at the centre of the residence. “Block” POR’s were modeled as 4.5 m height over the entire area (not at the centre of the area).

4.2 Noise Receptor Classification

All POR’s impacted by the project are classified as Class 2 Areas – a mix of urban and rural noise characteristics. This is consistent with the institutional and suburban nature of the turbine surroundings and with the previous CofA for the site. Table 3 on the following page describes and classifies the POR’s included in the calculation.

5 DETAILED NOISE IMPACT ASSESSMENT

5.1 Calculation Method

Calculated noise levels for all POR’s were determined using the “General” ISO 9613-2 calculation method built into WindPro 2.7.

5.2 Atmospheric Sound Attenuation

The analyses in this report assumed sound attenuation conditions between the turbine and POR’s corresponding to 100 C and 70% relative humidity. These atmospheric conditions are the most favourable to sound propagation and therefore produce the most conservative noise model. The attenuation coefficients used for each octave band (listed in Appendix A) are in accordance with “Interpretation for Applying MOE NPC Technical Publications to Wind Turbine Generators, October 2008” document.

5.3 Ground Porosity

A global ground porosity value of 0.7 was used in all modeling.

5.4 Additional Considerations

As previously described, the nearest adjacent wind project is more than 5 km from the site. Furthermore, the proposed project does not have a transformer substation and does produce tonal noise. These elements are not part of the noise calculations in this report.



6 RESULTS AND COMPLIANCE

6.1 Calculated Noise Levels

Table 4 presents a summary of noise levels for all points of reception, calculated using the ISO 9613-2 calculation method built into WindPro 2.7. The results for the lone participating receptor are shown in Table 5. The calculation details are summarized in Sections 2 to 5 and in Appendix A. Appendix A also contains maps showing noise contours for 10 m/s wind speeds (the worst case).

6.2 Assessment of Compliance

Noise levels at all POR’s are in compliance with the requirements outlined in the “Interpretation for Applying MOE NPC Technical Publications to Wind Turbine Generators, October 2008” document. The previous noise impact assessments performed for unconstrained turbine operation at 800 kW also showed that the noise levels at all POR’s were in compliance with the aforementioned requirements.
