A description of the activities/processesat the site for the reporting year. Thisshould include information such asproduction increases or decreases on site,any infrastructural changes,environmental performance which wasmeasured during the reporting year andan overview of compliance with yourlicence listing all exceedances of licencelimits (where applicable) and what theyrelate to e.g. air, water, noise.

Whitegate Power Station is a Combined Cycle Power Plant (CCGT), which utilises natural gas and distillate oil asfuel to generate up to 450 MW of electricity for supply to the NationalGrid. The site is located to the southwest ofWhitegate village, County Cork on the Fort Davis Road. The power station site is approximately ten hectares.Neighbouring lands are used for a variety of activities, including: an adjacent oil refinery, a gas bottling plantdepot, agricultural activities, and the Fort Davis fortifications to the west. Bord Gais Eireann (Owner) is the IELicence holder and has contracted General Electric Operations and Maintenance (GE O&M) to operate andmaintain the power station and its environmental policy, aspects and impacts on their behalf.

Declaration:All the data and information presented in this report has been checked and certified as being accurate. The

There were incidences of exceedance of the IGVs for Manganeseand Total Petroleum Hydrocarbons (TPHs) observed in somesamples in upgradient well waters in 2014 (Theses incidences werealso recorded in previous years 2012 and 2013). An investigationwas undertaken by ARUP at the time, and submitted to the EPA.The laboratory results are generally in decline from historic valuesfor the various boreholes with some increases and some decreasesin heavy metals and hydrocarbon parameters, but generally animproving trend over time. Upgradient wells include BH01, BH02,BH03, BH04, BH05, BH06, BH08. BH01 has shown a decline in heavymetal concentration in 2016 from 2015 figures, BH03 has shown aslight rise in Manganese concentration to average of 48.5ug/l. BH04has shown an increase in the concentration of manganese from thehighest value of 4090ug/l in 2015 to value of 6132ug/l in 2016 andTPH rose slightly in the November 2016 sampling from that in May.This bore BH04 has shown historically to have rises and falls in theconcentration of these elements since 2012. BH05 has shown aslight increase in Manganese concentration but a drop in Titanium.Max concentration TPH in 2015 was 17ug/l but in 2016 <10ug/l.Mercury in BH06 had max concentration rise from 0.02ug/l in 2015to 0.06ug/l in 2016. Manganese max concentration in BH 08 hasdropped from 3101ug/l to 999ug/l with Nickel also dropping from22ug/l to <2 ug/l, and Titanium from 89 ug/l to <5ug/l, and TPHdown from 75ug/l to <10ug/l. BH07A has shown a very slight rise inarsenic levels from <2.5 to 3.5ug/l, but has shown a decrease in anumber of elements Max Concentration Values; Chronium downfrom 3.10 to <1.5ug/l, Cobalt dropped from 2.7 to <2ug/l, Copperdown from 9.2 to <7ug/l, Manganese down from 150 to 80ug/l ,Ttitanium down from 9 to <5ug/l, and TPH down from 75 to <10ug/l.BH09 Arsecnic concentration showing a decrease as has copper,cobalt and maganese, titanium, TPH.

Was noise monitoring a licence requirement for the AER period?If yes please fill in table N1 noise summary below

Was noise monitoring carried out using the EPA Guidance note, including completion of the"Checklist for noise measurement report" included in the guidance note as table 6?Does your site have a noise reduction planWhen was the noise reduction plan last updated?

The LAeq for the day time round one, two and threemeasurements was 44.0dB, 44.6dB and 48.3dB respectively. TheLAeq for the evening time measurement was 44.5dB and theLAeq for the night time round one and two measurements was40.0dB and 46.4dB respectively. The second measured nighttime round the LAeq levels are above the night time noise limitof 45dBL Aeq as set out in Guidance Note for Noise (NG4) [1].However, the major contributor to measured LAeq levels duringthis measurement is considered to be noise from activity withinthe car park. The constant and steady nature of noise generatedby the Power Station, can be referenced as the LA90. The LA90for the day time round one, two and three measurements was33.9dB, 33.0dB and 33.0dB respectively, evening timemeasurement was 35.1dB and the L A90 for the night timemeasurements was 35.0dB and 33.6dB respectively. MeasuredLA90 values as deemed attributable to the Power Station arebelow the day, evening and night limits of 55dB, 50dB and 45dBLA90 as set out in Guidance Note for Noise (NG4) [1].

The LAeq for the day time round one, two and threemeasurements was 56.0dB, 53.5dB and 53.4dB respectively. TheLAeq for the evening time measurement was 44.6dB and theLAeq for the night time round one and two measurements was48.0dB and 51.5dB respectively. The measured day time roundone and the measured night time round two LAeq levels areabove the day and night time noise limit values of 55dB and45dB LAeq as set out in Guidance Note for Noise (NG4) [1].However as mentioned above, the major contributor tomeasured LAeq levels during this measurement is considered tobe noise from passing cars. Due to the constant and steadynature of noise generated by the Power Station, the LA90 asdiscussed above can be referenced to determine the specificnoise level from the facility at this location. The LA90 for the daytime round one, two and three measurements was 33.5dB,33.8dB and 32.6dB respectively. The LA90 for the evening timemeasurement was 35.9dB and the LA90 for the night time roundone and two measurements was 34.1dB and 30.1dB respectively.Measured LA90 values as deemed attributable to the PowerStation are below the day, evening and night limits of 55dB,50dB and 45dB LA90 as set out in Guidance Note for Noise (NG4)[1].

Noise monitoring summary report

Have there been changes relevant to site noise emissions (e.g. plant or operational changes) since the last noisesurvey?

Table N1: Noise monitoring summary

If noise limits exceeded as a result of noise attributed to site activities, please choose the corrective action from the following options?

25

** please explain the reason for not taking action/resolution of noise issues?

In June 2016, Silencers were installed on the Hogger Relief Vents and the PRV. In July, an acoustic barrier was installed around the site of the Hogger. Thepurpose of these noise control measures was to reduce the tonal component that was been reportly heard during start-up process from this system. Sincethat date, Whitegate have had experienced no further complaints regards noise. Further noise assessments have been undertaken to demonstratereduction that there is no detected tonal or impulsive components by Allegro Acoustics in November 2016. Assessment included at end.

EXECUTIVE SUMMARY

Previous noise assessments carried out by Allegro Acoustics on behalf of Whitegate Power Station (DC1119 & DC1415) concluded that Whitegate Power Station is inaudible at Graball Bay when online and operating normally. However, the operation of the Hogger and Safety Relief Valve (SRV), which are used during the Power Station’s start up procedure were thought to result in noise annoyance at a residential dwelling in Graball Bay. To address this potential issue, acoustic attenuators were installed on the Hogger Exhaust (2) and SRV Outlet (1). In addition, an acoustic screen was installed to minimise the residual noise generation from these plant items towards Graball Bay. These measures were completed in July 2016.

To verify the effectiveness of these mitigation measures, noise monitoring was carried out at Graball Bay from 23:00 on the 22nd of November 2016 until 07:00 on the 23rd of November 2016. This specific period was chosen due to neutral weather conditions. Both the Hogger and SRV were activated during this time. Whitegate Power Station was otherwise online for the duration of the noise survey.

Measured noise data was analysed to ensure that there was no evidence of elevated noise levels, impulsive or tonal noise at Graball Bay while the Hogger and SRV were operating. The measured noise levels were also compared to the night time noise limits, outlined for Whitegate Power Station in Industrial Emissions Licence (IEL) PO830-02. The summarised results from this noise assessment are as follows:

Hogger

The Hogger was activated from 03:05 until 03:30 on the 23rd of November 2016. No elevated noise levels or tonal noise attributable to Whitegate Power Station was measured at Graball Bay during this time, thereby indicating that the Hogger is now inaudible at Graball Bay. This can be seen in the table and figure below.

Measurement Start Time Duration dB LAeq dB LA90 dB LAFMax

23/11/2016 02:30 00:30:00 37.2 34.9 46.0

23/11/2016 03:00 00:30:00 36.2 34.2 48.7

23/11/2016 03:30 00:30:00 36.4 34.3 47.0

Table: Noise levels measured at Graball Bay before, after and while the Hogger was operating. Measured noise levels while Hogger was operating are denoted in bold.

Figure: 1/3rd Octave Band Frequency Analysis of a measurement taken at Graball Bay while the Hogger was operating compared with noise measurements taken when it was off. As can be seen, there is no noticeable difference in the noise climate across the 1/3rd octave spectrum while the Hogger was operational (Blue), compared with while it was off (Yellow and Grey).


Safety Relief Valve (SRV)

The SRV was activated from 03:10 to 03:11 and from 03:20 to 03:21 on the 23rd of November 2016. When the SRV operates, it emits quick blasts as it releases pressure from the Hogger system. The audibility of this process would be identifiable at Graball Bay by an increase in the LAFmax and LAeq statistical indicator while the SRV was operating. A previous noise assessment carried out by Allegro Acoustics identified that the SRV causes elevated sound energy at Graball Bay in the 1kHz to 8kHz frequency range.

The tables and graphs below show that there is no spike in the measured LAFmax or LAeq or in sound energy in the 1kHz to 8kHz frequency range at Graball Bay while the SRV is operating. This indicates that the SRV is inaudible at Graball Bay.

Figure: 1/3rd Octave Band Frequency Analysis of a measurement taken at Graball Bay while the SRV was activated compared with noise measurements taken when the SRV was not operating.

Industrial Emissions Licence

The measured noise levels throughout the noise survey were compared with the 45dB LAeq night time noise limit outlined for the Power Station in IEL PO830-02. The graphs below show that Whitegate Power Station remained below this 45dB night time noise limit at all times throughout the noise survey and that there was no evidence of tonal noise attributable to Whitegate Power Station.

Allegro Acoustics therefore considers Whitegate Power Station to be demonstrating compliance with Industrial Emission Licence PO830-02.

1 INTRODUCTION

Allegro Acoustics was retained by Whitegate Power Station to undertake environmental noise monitoring to verify the effectiveness of noise mitigation measures undertaken by the Power Station to the Hogger Exhaust and SRV Outlet in response to a noise nuisance complaint from a resident in Graball Bay.

Previous noise assessments carried out by Allegro Acoustics on behalf of Whitegate Power Station (DC1119 & DC1415) concluded that the Power Station is inaudible at Graball Bay when online and operating normally. However, the operation of the Hogger and Safety Relief Valve (SRV), which are used during the Power Station’s start up procedure were thought to result in noise annoyance at a residential dwelling in Graball Bay. To address this potential issue, acoustic attenuators were installed on the Hogger Exhaust (2) and SRV Outlet (1). In addition, an acoustic screen was installed to minimise the residual noise generation from these plant items towards Graball Bay. These measures were completed in July 2016.

To verify that potential noise from the Hogger and SRV has been successfully mitigated, continuous noise monitoring was carried out at Graball Bay from 23:00 on the 22nd of November 2016 until 06:30 on the 23rd of November 2016.

The Power Station was online throughout this noise survey and the Hogger and SRV were activated during the noise survey. All noise mitigation measures at Whitegate Power Station pertaining to the Hogger and SRV were finished and in place prior to the noise survey taking place.

The measured noise data at Graball Bay was analysed to ensure that there was no evidence of elevated noise levels, impulsive or tonal noise at Graball Bay while the Hogger and SRV were operating. The measured noise levels were also analysed to ensure that Whitegate Power Station is demonstrating compliance with the night time noise limit values, outlined for the Power Station in Industrial Emissions Licence (IEL) PO830-02.

1.1 Description of Major Noise Sources

The noise sources considered as part of this assessment are described below:

Safety Relief Valve Outlet – this outlet was previously located at a height of 23m above ground level between the ACC Fan enclosure and Turbine Building. This outlet has been relocated and is now at a height of 17m. Noise emanates from this outlet if the steam pressure in the Hogger line gets too high and the valve must open to reduce pressure upon the line. When this valve opens, steam can be seen and heard rapidly “blasting” from the outlet. When active, this is the most dominant noise source at the Power Station. This element only operates occasionally and for short durations (between 15s and 45s).

Hogger Exhaust – these are the two outlets of the Hogger system visible at either end of a C duct located above the Hogger silencer. The Hogger Exhaust pipes are also located between the ACC fan enclosure and Turbine Building and are at a height of 17m above ground level. While the Hogger is in full operation, there is a constant noise emitted from both of these pipes. There is also an occasional “whine” from both pipes and steam can typically be seen and heard “popping” out of both exhaust pipes. This has been found to be the second most dominant noise source at the Power Station.

To mitigate these items, Allegro Acoustics have designed and overseen the installation of noise mitigation measures to attenuate the Hogger and SRV. These mitigation measures comprised of the installation of an acoustic screen at the Hogger and SRV in addition to acoustic attenuators fitted to the Hogger Exhaust (2) and SRV Outlet (1).


1.2 Description of Terminology

Noise indicators referenced throughout this report are defined below.

LAeq: Equivalent Continuous A-weighted Sound Level. The continuous steady noise level, which would have the same total A-weighted acoustic energy as the real fluctuating noise measured over the same period of time.

LA90: The A-weighted noise level that is equalled or exceeded for 90% of the measurement period. This is typically used to indicate the background noise level at a location. This indicator can also be used to determine the specific noise level attributable to a constant noise source at a location.

LAFmax: The A-weighted maximum noise level that is measured throughout a noise measurement. The impulsive noise previously observed to emanate from the SRV can be quantified and identified using the LAFMax.

1/3rd Octave Band Analysis: Frequency analysis of sound such that the frequency spectrum is sub divided into bands of one third of an octave each. This analysis can be used to identify a tonal component to audible sound (note such as a hum, whine or whistle). The “whine” previously observed to emanate from the Hogger can be quantified and identified using 1/3rd octave band analysis.

2 METHODOLOGY

2.1 Noise Monitoring Location

Noise monitoring was carried out between 23:00 on the 22nd of November 2016 and 06:30 on the 23rd of November 2016 at a residential dwelling in Graball Bay. This monitoring location is situated approximately 2.5km from Whitegate Power Station across the Cork Bay and is denoted in Figure 1 below as monitoring location N1.

The sound level analyser was located in the front garden of the property and oriented towards the power station. The microphone was positioned at a height of approximately 2m. Otherwise, the microphone was located at least 3.5m away from any sound reflecting surfaces. A windshield was placed on the microphone to reduce any wind interference during measurements.

Figure 1: Satellite image showing Whitegate Power Station and noise monitoring location N1 at Graball Bay.


2.2 Noise Measurement Instrumentation

Noise measurements were taken using a Cirrus CR:171B Sound Level Meter (SLM) which measures simultaneously in every 1/3rd octave frequency band from 12.5Hz to 20 kHz. The Sound Level Meter was calibrated before and after noise measurements were carried out using a Bruel and Kjaer Type 4231 acoustic calibrator. Calibration certification, SLM serial number, calibrator used and microphone serial number for the SLMs are presented in the factory calibration certificate as displayed in Appendix C. The Cirrus CR:171B is a Class 1 instrument in accordance with IEC 61672 and IEC 60651. The Time Weighting used was Fast and the Frequency Weighting was A-weighted as per IEC 61672.

2.3 Assessment Criteria

Measured noise levels are assessed herein with specific reference to Condition 4.5 and Schedule B.4 of Whitegate Power Station’s Industrial Emissions License P0830-02. Condition 4.5 and Schedule B.4 are detailed below.

Figure 2: Excerpt taken from the IE license for the Power Station (PO830-02) showing Condition 4.5.

Figure 3: Excerpt taken from the IE license for the Power Station (PO830-02) showing Schedule B.4.

Cognisance is also paid in this assessment to the recommended noise limit criteria outlined in Guidance Note for Noise (NG4) [1]. The NG4 document [1] outlines the following recommended noise limits for residential or otherwise sensitive areas:

Daytime Noise Criterion, dB LAr,T (07:00 to 19:00hrs): 55dB

Evening Noise Criterion, dB LAr,T (19:00 to 23:00hrs): 50dB

Night-time Noise Criterion, dB LAeq,T (23:00 to 07:00hrs): 45dB

For the purposes of this noise survey, the noise levels measured at Graball Bay have been compared to the night time noise limit of 45dB LAeq as this is the most stringent noise limit for the Power Station.

It is worth noting that the LAeq statistical noise indicator takes all audible noise into consideration, the measured LAeq noise level can often include the noise generated by other sources such as passing road traffic and localised people movements.

In the case of Whitegate Power Station which when online, generally operates as a constant noise source without any intermittent or impulsive characteristics, the LA90 statistical indicator may be considered representative of the specific noise level from the facility and should also be compared to the 45dB night time noise limit outlined in the Power Station’s IEL and in Guidance Note for Noise (NG4) [1].


The LA90 statistical indicator is recognised as being representative of the background noise level at a location and is defined as follows:

The noise level that is equalled or exceeded for 90% of the time – the L90 statistical noise indicator is an indicator of the constant background noise level at any location.

2.4 Determination of Tonal Character

Both Guidance Note for Noise (NG4) [1] and Whitegate Power Station’s IEL state that there should be no clearly audible tonal or impulsive component from the Power Station at the nearest residential or otherwise noise sensitive receptor.

Impulsive noise can be identified using the LAFmax statistical indicator and tonal noise can be be identified by determining if one particular 1/3rd octave frequency band exceeds both its adjacent 1/3rd octave frequency bands by a significant number of decibels. The following guidelines are outlined in Guidance Note for Noise (NG4) [1] to conclude a tonal characteristic to the specific noise emanating from a facility:

Referring to the sound pressure levels in each 1/3rd octave band: The appropriate level differences vary with frequency. They should be greater than or equal to the following values in both adjacent 1/3rd octave bands:

15dB in low-frequency 1/3rd octave bands (25Hz to 125Hz)

8dB in middle-frequency bands (160Hz to 400Hz)

5dB in high-frequency bands (500Hz to 10,000Hz)

2.5 Meteorological and Local Environmental Conditions

Weather data for the monitoring period has been obtained from the Met Éireann weather station at Cork Airport. This monitoring station shows that weather conditions were suitable for the taking of noise measurements as there was no significant rainfall and that wind speeds generally remained below 5m/s throughout the monitoring period. A summary of the weather data for the monitoring period is available to view in Appendix B.

3 RESULTS

Noise monitoring was carried out while the Power Station was online and operating as normal. Both the Hogger and SRV were manually activated during the noise survey. Table 1 below show the times that the Hogger and SRV were operating. A full table of Leq and L90 1/3rd Octave data for each measurement is available to view in Appendix A.

3.1 Hogger

Table 2 below shows the measured noise levels before, after and while the Hogger was operating, these noise levels can be compared with each other to show that the Hogger does not result in an increase or significant change in LAeq, LA90 or LAFMax noise levels at monitoring location N1 at Graball bay. This indicates that the Hogger is likely to be inaudible at Graball Bay.

Table 2: Noise levels measured at Graball Bay while the Hogger was operating. Measured noise levels while Hogger was operating is denoted in bold.

Figure 4 below show the measured noise level in each 1/3rd Octave frequency band while the Hogger was operating and also compares the measured noise level in each 1/3rd Octave frequency band while the Hogger was operating with corresponding measured noise data from when the Hogger was not operating.

Figure 4 shows that there were no tonal components measured while the Hogger was operating. This graph also shows that the Hogger operating does not result in an increase or significant change in noise levels in any of the 1/3rd Octave bands when compared to corresponding measurements taken while the Hogger was off. This indicates that the previously identified “whine” from the Hogger is likely to be inaudible at Graball Bay.

3.2 Safety Relief Valve (SRV)

Table 1 above shows that the SRV was operating between 03:10 and 03:11 and between 03:20 and 03:21 on the 23/11/2016. Table 3 below shows the measured LAeq, LA90 and LAFMax noise level as concluded using NoiseTools Software by Cirrus Research for the specific 1 minute period during which the SRV was operating.

Start Time Duration dB LAeq dB LA90 dB LAFMax

23/11/2016 03:10 00:01:00 35.7 34.0 38.3

23/11/2016 03:20 00:01:00 38.0 36.7 40.4

Table 3: Noise levels measured at Graball Bay (N1) while the SRV was operating.


When the SRV operates, it emits quick blasts as it releases pressure from the Hogger system. If noise from the SRV was audible at Graball Bay, this would appear as an increase in LAFMax noise levels at N1. The measured LAFMax values throughout the entire measurement period are shown in Figure 5 below. As can be seen in Figure 5, the operation of the SRV does not give rise to elevated LAFMax values. This indicates that the impulsive, instantaneous sound generated by the SRV has not been measured at Graball Bay and that the SRV is likely inaudible at Graball Bay.

Figure 5: LAFmax noise levels measured at Graball Bay (N1) during the noise survey.

The blasts from the SRV would also appear as large spikes in the LAeq time history for the measurement. Figure 6 below shows that there are no significant or sudden spikes in the measured LAeq during the periods where the SRV was operating. The periods were the SRV is operating are marked in green. The large spike shown in Figure 6 at 03:25 is discussed below.

Figure 6: Breakdown of the LAeq time history for the 30 minute measurement taken while the SRV was activated, the periods were the SRV is operating are marked in green.


A large spike in measured LAeq can be seen in Figure 6 above at 03:25. Figure 7 below shoes a zoomed in view of the spike in measured LAeq. It can be seen that this elevation in LAeq lasts for approximately 10 seconds. During this time, the measured LAeq increases over approximately 5 seconds, reaches its maximum and then and then decreases over approximately 5 seconds. Based on this pattern, it is highly likely that this spike in LAeq is attributable to vehicular movement at the crossroad near N1. Importantly, there was no specific Hogger or SRV activity during this time and the noise level pattern (gradual rise, peak, gradual decay) does not correlate with any noise source at Whitegate Power Station.

Figure 7: Zoomed in view of the elevated LAeq seen in Figure 6 above at 03:25.

A previous noise survey carried out by Allegro Acoustics (DC1415-01) found that the operation of the SRV was identifiable at monitoring location N1 in Leq data at frequencies between 1kHz and 8kHz. This is shown in Figure 8 below.

Figure 8: Extract from a previous report (DC1415) issued by Allegro Acoustics showing elevated sound energy in the 1kHz to 8kHz range while the SRV was activated.


By comparing Figures 8, 9 and 10 it can be seen that following the implementation of mitigation measures, the previously identifiable elevated noise levels between the 1kHz to 8kHz bands, are no longer identifiable.

Figures 9 and 10 also compares the measured noise level in each 1/3rd Octave frequency band while the SRV was operating with corresponding measured noise data from when the SRV was not operating. Figures 7 and 8 show that the SRV operating does not result in an increase or significant change in noise levels in any of the 1/3rd Octave bands when compared to corresponding measurements taken while the SRV was off. This also indicates that the SRV is likely to be inaudible at Graball Bay.

Table 4 and Figure 11 below show the measured noise levels recorded at monitoring location N1 at Graball Bay during the noise survey while Whitegate Power Station was online and operating as normal. This table and graph show that both the measured LAeq and LA90 remain below the night time noise limit of 45dB outlind in IE Licence PO830-02 throughout the noise survey.

Figure 11: LAeq and LA90 noise levels measured at Graball Bay (N1) during the noise survey. The night time noise limit of 45dB is marked in green.

Figure 12 below displays the measured Leq and L90 noise levels in each 1/3rd Octave Band between 12.5Hz and 20kHz for four measurements chosen at random from the measured noise data. These graph shows that were no tonal components measured at monitoring location N1. A full table of Leq and L90 1/3rd Octave data for each measurement is available to view in Appendix A.


It is worth nothing however that in some of the 1/3rd Octave graphs presented in Figure 4 below and in Appendix A, elevated sound energy is present between 31.5Hz and 50Hz. This sound energy is considered to be attributable to a residential oil boiler operating on an intermittent basis close to monitoring location N1. Previous noise surveys carried out at Whitegate Power Station (DC1119) did not find any sources of elevated sound energy at frequencies between 31.5Hz and 50Hz and this elevated sound energy is not considered to be attributable to Whitegate Power Station.

Figure 12: Measured Leq and L90 noise levels at N1 in each 1/3rd Octave Band between 12.5Hz and 20kHz.

4 CONCLUSION

This noise survey has demonstrated that the noise mitigation measures carried out on the Hogger Exhaust and SRV Outlet have successfully reduced the noise emanating from the these items sufficiently so that they are no longer audible at Graball Bay and therefore should not result in any annoyance to residents living in Graball Bay.

As the measured noise levels during the survey remained below the the night time noise limit of 45dB LAeq outlind in IE Licence PO830-02 and that there is otherwise no evidence of tonality or impulsivity that is attributable to Whitegate Power Station, Whitegate Power Station is considered by Allegro Acoustics to be demonstrating compliance with the noise limits outlined in IE Licence PO830-02.
