Sound power level Lw [dB] 117 123 121 122 124 123 125 125 119 132

Sound power level is based on measurement made according to standard ISO 9614-2:1996 Acoustics -- Determination of sound power levels of noise sources using sound intensity --Part 2: Measurement by scanning. This is to be treated as primary noise data for engine.

b. Spatial averaged sound pressure level

Typical spatial averaged A-weighted sound pressure level inside engine hall is 110 dB(A). The spatial average sound pressure value represents noise incident on engine hall walls and could then be used for power plant structure acoustic design.

c. Surface averaged sound pressure level

Typical surface averaged A-weighted sound pressure level of Wärtsilä genset is 115 dB(A) at 1 m distance. In case of separate concrete engine cell installation, absorption material may be needed in the engine cell to reduce unnecessary reflections and reach the stated value.

Noise Impact Study Grange Backup Power Ltd. 7xW18V50DF Day and Evening Time

Calculation method

The modelling is made according to the method described in International Standard ISO 9613-2 Acoustics – Attenuation of sound during propagation outdoors – Part 2: general calculation method. The actual software implementation of the method is Cadna A version 4.4.

All the noise sources are defined as point sources. The source properties are defined as source noise emission or sound power level data at standard 1/1-octave band frequencies 31.5…8000 Hz with corresponding attenuations due to silencers and structures. From these, the overall A-weighted equivalent sound pressure level at receiver or calculation grid locations is calculated and used height is 1.5 m.

The noise zones drawn to the noise map are receiver grid point results under meteorological conditions favourable to sound propagation. The noise model does not take into consideration ambient conditions such as ambient background noise levels or short-term wind conditions.

Assumed equipment specification

The model assumed in this document is a W18V50DF power plant when radiator fan speed at 440 rpm is 69 % (304 rpm) at day and evening time, EG-set running at 100 % load and is based on site layout drawing DBAD255939 rev.-.

Power plant noise impact and cumulated noise levels

Wärtsilä power plant noise impact is estimated at 5 noise sensitive locations (NSL) marked NSL1, NSL2, NSL3, NSL4 and NSL5 as seen on the noise map in page 4. These same measurement locations are presented in the Environmental Report document chapter 8, Table 8.1: Description of Noise Monitoring Points.

Measurement results presented in the Environmental Report are used as existing background noise levels (LAeq and LA90) in Table 2 and 3 during day and evening time, including the distance from the noise monitoring points to the proposed site boundary. Day and evening time noise levels were measured at all 5 NSLs.

Estimate of Grange Backup power plant noise impact during day and evening time is shown on the 5th column in Table 2 and 3 respectively. Cumulative noise level column shows the estimated total level including noise impact from Wärtsilä power plant and existing background noise level. The difference between cumulative noise level and background noise level at each location is shown on the 7th column in Table 2 and 3. In this model, the equivalent continuous A-weighted sound pressure levels LAeq is only considered as the noise measurement parameter for the cumulative noise level.

Calculation method

The modelling is made according to the method described in InternationalStandard ISO 9613-2 Acoustics — Attenuation of sound duringpropagation outdoors — Part 2: general calculation method. The actualsoftware implementation of the method is Cadna A version 4.4.

All the noise sources are defined as point sources. The source propertiesare defined as source noise emission or sound power level data atstandard 1/1-octave band frequencies 31 .5...8000 Hz with correspondingattenuations due to silencers and structures. From these, the overall A-weighted equivalent sound pressure level at receiver or calculation gridlocations is calculated and used height is 1.5 m.

The noise zones drawn to the noise map are receiver grid point resultsunder meteorological conditions favourable to sound propagation. Thenoise model does not take into consideration ambient conditions such asambient background noise levels or short-term wind conditions.


The model assumed in this document is a W18V50DF power plant whenradiator fan speed at 440 rpm is 58 % (255 rpm) at night time, EG-setrunning at 100 % load and is based on site layout drawing DBAD255939rev.-.

Wärtsilä power plant noise impact is estimated at 2 noise sensitive locations (NSL) marked NSL1 and NSL2 as seen on the noise map in the next page. These same measurement locations are presented in the Environmental Report document chapter 8, Table 8.1: Description of Noise Monitoring Points.

Measurement results presented in the Environmental Report are used as existing background noise levels (LAeq and LA90) in Table 2 during night time, including the distance from the noise monitoring points to the proposed site boundary. Night time noise levels were measured at only 2 NSLs.

Estimate of Grange Backup power plant noise impact during night time is shown on the 5th column in Table 2. Cumulative noise level column shows the estimated total level including noise impact from Wärtsilä power plant and existing background noise level. The difference between cumulative noise level and background noise level at each location is shown on the 7th column in Table 2. In this model, the equivalent continuous A-weighted sound pressure levels LAeq is only considered as the noise measurement parameter for the cumulative noise level.

Electromagnetic fields and Bats: Note on potential for adverse impacts on fauna. The new power station will generate electricity for the national grid at 50 Hz frequency. Electrical equipment which generates or uses AC electricity, as well as conductors which carry it, generate extra low frequency (ELF) electromagnetic fields. Anything that runs on electricity generates a magnetic field and also electromagnetic field (EMF). There are many studies that have researched the safety requirements to protect humans for prolonged exposure to EMFs but fewer studies that have clearly established the effects on fauna in the vicinity of the EMF source. In 2006 Nicholls and Racey1 recorded bat activity along an electromagnetic gradient at ten radar installations throughout Scotland in a study that was aimed at seeing if radar could be used as a bat deterrent. Their results revealed that bat activity and foraging effort per unit time were significantly reduced in habitats exposed to an electromagnetic field strength of greater than 2v/m when compared to matched sites registering EMF levels of zero. Even at sites with lower levels of EMF exposure (,2v/m), bat activity and foraging effort was significantly reduced in comparison to control sites. This experiment demonstrated that an electromagnetic signal from a small radar unit with a fixed antenna invariably reduced the foraging activity of bats within 30 m of the unit. Nicholls and Racey suggest that the aversive behavioural response of foraging bats to electromagnetic radiation may be a result of thermal induction. There has been no published testing of use of EMF as a bat deterrent in practice. This experiment used a narrow beam of radar focussed on the area of bat activity. The study noted that greater research was required into looking at different multi-directional patterns of EMF emissions. Therefore the effects of EMF on bats in other scenarios is not fully understood. The majority of electrical and electronic equipment used in the proposed power station will be installed indoors and will be shielded. With the exception stated below, the power station itself will not contain any high-voltage cables or devices. Thus, none of those devices will emit electromagnetic fields strong enough to pose human health concerns. Hence there are no restricted access zones even inside the power station buildings. The sole exception to this will be the interconnection between the power station and existing 110 kV power grid substation. Uninsulated overhead high voltage power lines do generate stronger electromagnetic fields. 1 Nicholls B, Racey PA (2009) The Aversive Effect of Electromagnetic Radiation on

Even at sites with lower levels of EMF exposure (,2v/m), bat activity and foraging effort was significantly reduced in comparison to control sites. This experiment demonstrated that an electromagnetic signal from a small radar unit with a fixed antenna invariably reduced the foraging activity of bats within 30 m of the unit. Nicholls and Racey suggest that the aversive behavioural response of foraging bats to electromagnetic radiation may be a result of thermal induction. There has been no published testing of use of EMF as a bat deterrent in practice. This experiment used a narrow beam of radar focussed on the area of bat activity. The study noted that greater research was required into looking at different multi-directional patterns of EMF emissions. Therefore the effects of EMF on bats in other scenarios is not fully understood. The majority of electrical and electronic equipment used in the proposed power station will be installed indoors and will be shielded. With the exception stated below, the power station itself will not contain any high-voltage cables or devices. Thus, none of those devices will emit electromagnetic fields strong enough to pose human health concerns. Hence there are no restricted access zones even inside the power station buildings. The sole exception to this will be the interconnection between the power station and existing 110 kV power grid substation. Uninsulated overhead high voltage power lines do generate stronger electromagnetic fields. 1 Nicholls B, Racey PA (2009) The Aversive Effect of Electromagnetic Radiation on

cawleyElectromagnetic fields and Bats: Note on potential for adverse impacts on fauna.

The new power station will generate electricity for the national grid at 50 Hz frequency.Electrical equipment which generates or uses AC electricity, as well as conductors whichcarry it, generate extra low frequency (ELF) electromagnetic fields. Anything that runson electricity generates a magnetic field and also electromagnetic field (EMF). There aremany studies that have researched the safety requirements to protect humans forprolonged exposure to EMFs but fewer studies that have clearly established the effectson fauna in the vicinity of the EMF source.

However this interconnection will only consist of step-up transformers and the connection to the 110kV substation will be via an underground line. This is unlikely to significantly add to the existing EMF generated by the substation. The existing substation includes several conductors and exposed cables that will emit electromagnetic radiation far in excess of the link from the power station to the substation.
