1. EXECUTIVE SUMMARY

AWS Truepower, LLC, a UL company (“UL”), was retained by Glacier Sands Wind Power, LLC (the “Client”) to evaluate the turbine sound propagation of the proposed Glacier Sands Wind Project, located in central Illinois. The project is expected to consist of up to 53 turbines. For the purpose of this analysis, six turbine model scenarios were evaluated and are listed below in Table 1.1. The results of each scenario are presented in Appendix A through Appendix F. This report discusses the methods used to develop the turbine sound propagation estimates and presents the results of our analyses.

There are state noise regulations that have been determined by the Illinois Pollution Control Board on sound emission standards and limitations for property-line noise sources that are applicable to the project site. These regulations are presented in Part 901 of Title 35 regarding environmental protection. Section 901.101 defines classifications of land according to use. The land use classes applicable to this analysis are Class A and Class C, where Class A is defined as residential use, and Class C as agricultural. The Glacier Sands Wind Project turbines will be located on Class C land. Section 901.102 provides allowable octave band sound pressure levels, during both daytime and nighttime hours, emitted to any Class A land from Class C land, when measured at any point within the Class A land.

The turbine sound propagation of the proposed Glacier Sands Wind Project was estimated using the Openwind software. Openwind was developed by UL as an aid for the design, optimization, and assessment of wind power projects. The sound model in Openwind is based on ISO 9613-2, which is the international standard for sound propagation and attenuation of industrial noise. Various site specific inputs, along with the sound power levels by octave band for the turbine, were input into the software. The octave band spreading version of the model was used for this study in order to compare to the Illinois Pollution Control Board regulations.

Sound propagation by octave band was calculated for the proposed Glacier Sands Wind Project layout for six turbine model scenarios. Noise compliance was verified at the residences as well as along the yard lines of residential parcels.




The Vestas V162-5.6 MW, V150-4.2 MW and V138-3.0 MW turbine sound propagation was modeled; all residences and yard lines are expected to be compliant for both daytime and nighttime sound limits for these scenarios.

The Nordex N149-4500 turbine sound propagation was modeled, utilizing serrated trailing edge (STE) blades. All residences are expected to be compliant for both daytime and nighttime limits. The yard lines of Roger Garlisch and Michele Vaughn are expected to exceed the nighttime limit for multiple octave bands. However, both land owners are participating in the project and have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds.

The Siemens Gamesa SG 5.0-145 turbine sound propagation was modeled, in which three turbines (T1, T17 and T23) will operate with noise reduction system (NRS) mode N1. The residences of Roger Garlisch and Eldon Garlisch are expected to exceed the nighttime limit for the 2000 Hz octave band, however, both land owners are participating in the project and have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds. Multiple residential yard lines are also expected to exceed the nighttime sound limits for multiple octave bands. All residents with exceeding yard line sound levels have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds.

The GE 5.5-158 turbine sound propagation was modeled. The residence of Ellen Shawgo is expected to exceed the nighttime limit for the 1000 Hz octave band, however, the land owner is participating in the project and has provided a sound waiver to the Client with regards to the Illinois Pollution Control Board thresholds. Multiple residential yard lines are also expected to exceed the nighttime sound limits for multiple octave bands, however, all residents with exceeding yard line sound levels have provided sound waivers to the Client with the exception of the James Campbell residence. It should be noted that the GE 5.5-158 turbine was modeled with the lowest sound power level currently available as specified by the turbine manufacturer. It is understood that discussions are on-going with the manufacturer to understand if additional sound mitigation options are available for this machine. If a sound waiver is unable to be obtained from James Campbell and no sound mitigation options are available from the manufacturer, the Client will consider removing T17 from the Project layout, which is the turbine that is expected to be causing the exceedance, in order to make James Campbell’s yard line sound compliant

3. BACKGROUND

3.1 Sound Perception The perception of sound at a given point in the vicinity of a wind project is determined by a number of factors. These factors include: distance from the source of sound to receptor, surrounding terrain, ambient sound level, time of day, wind direction, temperature gradient, and relative humidity. Sound characteristics such as amplitude (loudness), frequency (pitch), impulse patterns and duration all affect the potential for sound to be considered noise.

There are various filters that can be applied to sound meters to account for how the human ear perceives sound. The most commonly used is the A-weighting scale, which accounts for human hearing being more sensitive to sound from mid-level frequencies than sound at low or high frequencies. A-weighting is applied by adding values by octave band to sound levels and is designated with the units dB(A).

3.2 Turbine Sound Emissions Unlike some early wind turbine designs, sound emissions are less of a concern for modern megawatt-scale wind turbines, especially when sited a sufficient distance from dwellings. Aerodynamic sound has been reduced by adjusting the thickness of the blades’ trailing edges, by orienting the blades upwind of the turbine tower, and by dramatically reducing the rotor rotation rate. Sound generated by the mechanical components of the turbines has been largely reduced as a result of structure-borne sound insulation of the gearbox and generator. The cooling ducts are also baffled to further reduce sound emissions.

Most turbines begin operating when the wind speed is 3 m/s or greater. Although sound emissions from the turbines tend to increase as the wind speed increases, the ambient sound from the wind tends to be louder than the sound from the turbine at wind speeds above 8 - 9 m/s. While acceptable distances vary with the number of turbines, ambient background noise, and screening structures and vegetation, a distance of at least 1000 feet from occupied dwellings is typically used for wind turbine placement.

Figure 3.1 compares the average sound emissions from a typical megawatt-scale wind turbine at a receptor distance of 1000-2000 feet, relative to other common sounds.

4. NOISE REGULATIONS

4.1 Federal Regulations There are no federal noise regulations that are applicable to this project.

4.2 State Regulations There are state noise regulations that have been determined by the Illinois Pollution Control Board4.1 on sound emission standards and limitations for property-line noise sources that are applicable to the project site. These regulations are presented in Part 901 of Title 35 regarding environmental protection. Section 901.101 defines classifications of land according to use. The land use classes applicable to this analysis are Class A and Class C, where Class A is defined as residential use, and Class C as agricultural. The

4.1 llinois Pollution Control Board, Title 35: Environmental Protection, Subtitle H, Chapter 1, Part 901 - amended in R14-22 at 39 Ill. Reg. 16264, effective December 7, 2015




Glacier Sands Wind Project turbines will be located on Class C land. Section 901.102 provides allowable octave band sound pressure levels, during both daytime and nighttime hours, emitted to any Class A land from Class C land, when measured at any point within the Class A land. These allowable levels are presented in Table 4.1

4.3 County Regulations Section VIII of the Mason County Zoning Ordinance4.2 outlines specific regulations for wind energy conversion systems. Allowable sound levels must be compliant with the standards set forth by the Illinois Pollution Control Board. No additional noise regulations are specified. The zoning ordinance also specifies that turbines shall be setback at least 1500 feet from any primary structure. Although this is not specifically in reference to sound, siting turbines a considerable distance from occupied dwellings will help to reduce the impacts of sound.

5. SOUND MODEL

The turbine sound propagation of the proposed Glacier Sands Wind Project was estimated using the Openwind software. Openwind was developed by UL as an aid for the design, optimization, and assessment of wind power projects.5.3 The sound model in Openwind is based on ISO 9613-25.4 which is the international standard for sound propagation and attenuation of industrial noise. Under this standard, all sound sources are treated as point sources; all sound propagation is assumed to be in the same direction as the wind; atmospheric conditions are favorable to sound propagation; and wind speeds that are between 3 and 11 meters above ground level are assumed to be between 1 and 5 m/s.

4.2 Logan County Zoning Ordinance, Appendix E – Wind Energy Conversion Systems, https://www.logancountyil.gov

5.3 “Openwind – Theoretical Basis and Validation”, Version 1.3, AWS Truewind, LLC, April 2010.

5.4 International Standard, ISO 9613-2, First edition,– Reference Number: ISO9613-2:1996(E) - 15 Dec 1996




There are several types of attenuation, or decrease of the intensity of sound energy, considered in ISO 9613-2, and incorporated into the model within Openwind:

• Atmospheric - This is the conversion of sound energy into heat. • Geometric Spreading - As the hemisphere of sound travels outwards from its point source, the

sound energy is spread out over an area proportional to the distance squared. • Ground Effect - Soft or porous ground (e.g. soil, vegetation) tends to absorb sound energy,

whereas hard ground (e.g. concrete, ice, water, tamped earth) tends to reflect sound back upwards towards the observer.

The atmospheric attenuation coefficients are calculated using equations from ISO 9613-1 and the site relative humidity, temperature, and air density. Using on-site meteorological data and nearby reference station data, a relative humidity of 72%, a temperature of 10.9° C, and an air density of 1.225 kg/m3 were calculated for the site.

The observer height and ground porosity are both factors in calculating attenuation due to ground effect. An observer height of 1.75 m was used in this analysis, representing the height of an average to tall person. The ground porosity for the site was estimated using land classifications from the 2011 National Land Cover Database. The percent of the area considered to be soft ground was calculated as 95%; therefore a slightly conservative value of 0.9 was used in this analysis.

Additional inputs to the model include the turbine and receptor locations. The turbine layouts used in this analysis consist of the Vestas V162-5.6 MW, the Vestas V150-4.2 MW, the Vestas V138-3.0 MW, the Nordex N149-4500 utilizing STE blades, the Siemens Gamesa SG 5.0-145 (three turbines utilizing NRS mode N1), and the GE 5.5-158, individually. The STE (Serrated Trailing Edge) variant of the Nordex N149-4500 allows for reduced turbine sound emissions through the use of trailing edge serrations on the turbine blades while maintaining the same energy production. The NRS (Noise Reduction System) N1 variant used for the Siemens Gamesa SG 5.0-145 reduces turbine sound output at the expense of lost energy production during certain conditions.

In this sound analysis, UL has accounted for the additional sound output due to the substation. Transformer sound specifications were provided by the Client with a maximum total sound power level of 82 dB. Proxy scale factors were derived to define the relationship between total and octave sound levels based on turbine sound behavior. These scale factors were used to determine the sound power level of the transformer by octave band to be used in the sound calculation. Actual sound power output from the transformer by octave band should be verified once the final transformer sound specifications are available.

Two sets of receptors were created for the analysis – receptors at primary structures, and receptors along the yard lines of the primary structures. The primary structure shapefile was provided by the Client. As the noise regulation specifies allowable limits at any point within the Class A residential land, UL also used aerial imagery to digitize yard lines around the primary structures. It is recommended that the locations of both sets of receptors are verified by a site visit. Coordinates for the receptors at primary structures are included for each scenario in the corresponding Appendix.

The octave band spreading version of the sound model was used for this study. In this model, turbine sound power levels by octave band are used to calculate attenuation separately for each octave band before combining the octave band sound pressure levels at the receptor. The total sound power level and A-weighted total sound power level by octave band for each turbine model were taken from manufacturer specifications provided by the Client. The A-weighting was removed in order to compare the output to the




values in the Illinois Pollution Control Board noise regulation. The manufacturer [dB(A)] octave band sound power levels and the calculated [dB] octave band sound power levels are presented for each scenario in the corresponding Appendix.

6. RESULTS

Given the sound model inputs specified above, sound propagation by octave band was calculated for the proposed Glacier Sands Wind Project layout. Sound pressure levels at 1000 Hz across the project area, which was the octave band with the overall sound pressure level closest to the limit, are presented for each scenario in the corresponding Appendix. Additionally, sound pressure levels by octave band at each of the primary structures can also be found for each scenario in the corresponding Appendix. These sound pressure levels are not time dependent; however, they can be compared to the maximum allowable daytime and nighttime limits presented in Table 4.1 to determine if any exceedances will occur.

The Vestas V162-5.6 MW, V150-4.2 MW and V138-3.0 MW turbine sound propagation was modeled; all residences and yard lines are expected to be compliant for both daytime and nighttime sound limits.

The Nordex N149-4500 turbine sound propagation was modeled, utilizing serrated trailing edge (STE) blades. All residences are expected to be compliant for both daytime and nighttime limits. The yard lines of Roger Garlisch and Michele Vaughn are expected to exceed the nighttime limit for multiple octave bands. However, both land owners are participating in the project and have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds.

The Siemens Gamesa SG 5.0-145 turbine sound propagation was modeled, in which three turbines (T1, T17 and T23) will operate with noise reduction system (NRS) mode N1. The residences of Roger Garlisch and Eldon Garlisch are expected to exceed the nighttime limit for the 2000 Hz octave band, however, both land owners are participating in the project and have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds. Multiple residential yard lines are also expected to exceed the nighttime sound limits for multiple octave bands. All residents with exceeding yard line sound levels have provided sound waivers to the Client with regards to the Illinois Pollution Control Board thresholds.

The GE 5.5-158 turbine sound propagation was modeled. The residence of Ellen Shawgo is expected to exceed the nighttime limit for the 1000 Hz octave band, however, the land owner is participating in the project and has provided a sound waiver to the Client with regards to the Illinois Pollution Control Board thresholds. Multiple residential yard lines are also expected to exceed the nighttime sound limits for multiple octave bands, however, all residents with exceeding yard line sound levels have provided sound waivers with the exception of the James Campbell residence. It should be noted that the GE 5.5-158 turbine was modeled with the lowest sound power level currently available as specified by the turbine manufacturer. It is understood that discussions are on-going with the manufacturer to understand if additional sound mitigation options are available for this machine. If a sound waiver is unable to be obtained from James Campbell and no sound mitigation options are available from the manufacturer, the Client will consider removing T17 from the Project layout, which is the turbine that is expected to be causing the exceedance, in order to make James Campbell’s yard line sound compliant

The sound modeling results represent a conservative estimate of the actual sound levels that may be experienced at receptor locations near the project site due to the following conditions:




• The sound modeling results represent a conservative estimate of the actual sound levels that may be experienced at receptor locations near the project site due to the following conditions:

• The sound model is designed mainly for use in flat or constantly sloping terrain. Terrain data is only used to calculate three-dimensional distances between source and receiver. The model does not take into account the fact that terrain features such as hills can act as barriers to the propagation of sound.

• Other obstacles to the propagation of sound, such as trees and buildings, are also ignored. • Ambient sound, such as the rustling of leaves, which tends to mask turbine sounds at higher wind

speeds, is ignored. • Possible sound mitigation efforts at the substation and switching station could be considered,

such as additional sound proofing of the loudest components of the transformer or creation of barrier walls.

Due to the conservative nature of the sound model, it was deemed reasonable to omit any uncertainty in the turbine sound power levels. On-site measurement is recommended to account for site-specific variables and conditions, such as ground porosity and locations of receptors. In the unlikely event that on-site measurement yields non-compliance once the project is operational, reductions of sound levels can be achieved by altering the turbine operating parameters used at the site. Many turbine models, including the Vestas V162-5.6 MW, Vestas V150-4.2 MW, Vestas V138-3.0 MW, Nordex N149-4500, and Siemens Gamesa SG 5.0-145, offer reduced sound output modes that can be used for certain turbine locations and during certain times of day. It should be noted that the GE 5.5-158 turbine was modeled with the lowest sound power level currently available as specified by the turbine manufacturer. It is understood that discussions are on-going with the manufacturer to understand if additional sound mitigation options are available for this machine. Additionally, the sound power levels for all Vestas machines modeled were listed as preliminary, as test results for those turbines are not yet available. Sound power levels for the Vestas models should be confirmed when available.
