1 INTRODUCTION

Malone O’Regan Environmental (MOR) were appointed by Glanbia Foods Ireland Ltd (Glanbia) to conduct a noise assessment survey at their facility that is located within the Clonminam Industrial Estate, Portlaoise, Co. Laois (the Site). The survey was conducted by competent MOR Acoustic Consultants on the 15th and 16th January 2019 and on the 25th and 26th February 2019.

This noise assessment report has been prepared in strict accordance with the Environmental Protection Agency (EPA) Compliance Investigation CI001581, which noted:

“The licensee shall conduct a noise assessment survey in accordance with the methodology specified in NG4 and as per Condition 6.14 & Schedule C.4 of the licence.

… The noise assessment survey report shall be submitted via monitoring licensee return on the EDEN Portal by 04th March 2019.”

1.1 Site Compliance Criteria

Industrial Emissions Licence (IEL) Register No. P1028-01 was issued by the EPA, to Glanbia on the 1st August 2017.

Condition 6.14 details the requirement to conduct a noise survey on an annual basis:

“The licensee shall carry out a noise survey of the site operations not later than seven months from the date of grant of this licence and annually thereafter. The noise survey shall pay particular regard to tonal and impulsive noise sources during night time operations. The survey programme shall be undertaken in accordance with the methodology specified in the ‘Guidance Note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities (NG4)’ as published by the Agency.”

Schedule C.4 Noise Monitoring notes four monitoring locations and the measurement parameters, along with the number of measurements to be undertaken during each time period. Although condition 6.14 states that noise monitoring should be conducted annually, frequency of monitoring is omitted from Schedule C.4.

Day time A minimum of 3 sampling periods at each noise monitoring location.Note2

Evening time A minimum of 1 sampling period at each noise monitoring location.

Night time Note1 A minimum of 2 sampling periods at each noise monitoring location.

Note 1 Night time measurements should be made between 2300hrs and 0400h, Sunday to Thursday, with 2300hrs being the preferred start time.

Note 2 Sampling period is to be the time period T stated as per Schedule B.4 Noise Emissions, of this licence. This applies to day, evening and night time periods



Additional conditions of the IEL that are relevant to this assessment include the following:

Condition 4.5 of the IEL notes:

“Noise from the installation shall not give rise to sound pressure levels that exceed the limit values specified in Schedule B.4 Noise Emissions of this licence measured at the boundary of the installation or at any noise sensitive location.”

Schedule B.4 Noise Emissions, identifies the following monitoring locations:

Monitoring Locations NML1 (North Boundary), NML2 (West Boundary), NML3 (South West Boundary), NML4 (East Boundary), and any other locations required by the Agency.

Schedule B.4 also specifies the monitoring duration and measurement criteria set out in Table 1-2:

Day time dB LAr,T

(30 minute)

Evening time dB LAr,T

(30 minute)

Night time dB LAeq,T

(15-30 minute)

55 50 45note1

Note 1: There shall be no clearly audible tonal component or impulsive component in the noise emission from the activity at any noise sensitive location.

Schedule B.4, note 1, states that site specific tones or impulsive components should not be clearly audible at NSLs during the night time period. This implies that, where tonal or impulsive components may arise on boundaries at night, monitoring should also be conducted at NSLs for compliance purposes.

1.1.1 Review of Monitoring Locations

A complete review was undertaken following receipt of the EPA’s recent instruction to complete a noise assessment survey to ensure that this report would be in strict accordance with the methodology specified in NG4, condition 6.14 and Schedule C.4 of the license as stipulated by the Agency.

NG4 Guidance stipulates ‘criteria noise levels’ for noise emissions arising from a licenced facility at Noise Sensitive Locations (NSLs). It does not include boundary locations, as stipulated in Schedule C.4 of IEL Register No. P1028-01, unless there is a proximity to an NSL. There is a clear inconsistency between the requirements of NG4 and IEL Register No. P1028-01 in this regard. Standard monitoring procedure within NG4 is to monitor in proximity to NSLs in determining compliance. Section 6.1 of NG4 conservatively supports the use of boundary, rather than NSL, monitoring positions, though it does note:

“…a boundary measurement location may not be representative of the sound levels at the receptor.”

This review focused on the NMLs presented in Noise Compliance Reports submitted to the Agency, both as part of the IE Licence application (JRE February 2017) and in subsequent compliance reports (JRE Oct 2017 & Shorcontrol March 2018).

It was concluded that the monitoring location on the Eastern boundary “NML 4” had been erroneously included in the previous compliance reports. This is because noise data compiled at this location would not be representative of noise emissions arising from the facility experienced at the closest NSLs to the Eastern boundary. This is a minimum requirement of the methodology outlined in NG4.



For the purpose of this noise assessment survey, NML 4 has been relocated to a more representative location on the Eastern boundary of the property to ensure compliance with both the Licence and NG4 Guidance. Please see Figure 1-1 below, which presents the locations of the 4 No. monitoring locations. The revised monitoring position for NML 4 was chosen by an appropriately qualified and competent noise consultant as the most appropriate location for the monitoring station on the Eastern boundary. The selected location ensures un-interrupted propagation of the sound wave from its source to the boundary, and from the boundary to eastern NSLs. The location has also been placed to enable a line of sight to the eastern NSLs (Abbey Court) and to the on-site emission sources, as per the methodology required by NG41. Additionally the monitoring point reduces the distorting potential for close proximity noise emissions impacting on the noise monitoring event, which would not be reflective of noise at the NSLs. The revised position also reduces undue influence arising from the neighbouring industrial facility, thereby improving the site specificity of the recorded noise values.

The revised NML 4 utilised for this noise assessment survey is also in strict accordance with Condition 6.14 and Schedule C.4 of the licence. Schedule C.4 specifies that monitoring must be undertaken along the Eastern Boundary, a requirement that is met by the revised NML 4.

Based on this review, we are satisfied that the noise monitoring locations to be utilised for this assessment meet both the criteria of IEL Register No. P1028-01 and the NG4 Guidance as stipulated by the Agency.

1.2 Description of Activities at the Site

An animal feed mill has operated since 1981 in the Clonminam Industrial Estate, Portlaoise, County Laois (Grid Ref. 646057E; 696057N) employing over 200 people in production and sales. Since 2014 the Site operates an Animal Feed Mill, Grain Store and an Oat Mill that produce separate products.

The Animal Feed Mill is for the production of cereal based animal feed for the agricultural industry, including mono-gastric (poultry) and ruminant feeds (cattle, sheep etc.). The finished production capacity for the Animal Feed Mill is 200,000 tonnes/year.

The Oat Mill is for the production of oat flakes for human consumption and its finished production capacity is 15,000 tonnes/year.

The installation falls within the scope of IEL Category 6.4 (b)(iii), under the Industrial Emissions Directive (IED)(2010/75/EU).

1.2.1 Noise Abatement Works since Previous Monitoring

The last compliance noise report was conducted in March 2018(Shorcontrol, 2018). Since then the following noise abatement works have occurred at the Site:

1.2.1.1 Grinder Room

In strict accordance with the Site’s Environmental Management System (EMS), the Grinder Room doors are kept closed during the operation of the grinders. In addition to the 2 No. grinder fans, a silencer within the Grinder House has been fitted on the central vacuum line and acoustically louvered doors have been fitted externally.

Silencers were installed onto both the Grinder 1 and Grinder 2 Fans in October 2018. A ‘significant’ decrease of c.12dB was noted for the combined sound emission level for both Grinder Fans 1 and 2.

1.2.1.2 Mill East Fan

The Mill East Fan (LAeq,T 72dB) was permanently decommissioned and removed to reduce noise at height on the eastern boundary. This fan was relocated to the western façade of the Mill building to obtain the required air extraction rates for the Mill building.

1.2.1.3 Intake Fans

The three (3No.) intake fans were relocated and mounted in a vertical position on the roof of the Intake Area building and fitted with three (3No.) silencers in November 2018.

1.2.1.4 Oat Mill

The four (4No.) Oat Mill Building fans were fitted with silencers in December 2018. The installed abatement measures result in a reduction of over 10dB at each fan.

1.3 Site Characteristics

The Site is bounded to the east by a rail-line and commercial units, including Telfords, Sliderobes and Browne’s Animal Feeds. To the north, the Site is bounded by the Old Knockmay Road, a cold storage business (Lyonara) and other industrial, warehousing and commercial units. A bungalow, vacant during this monitoring event, is also located to the north of the Old Knockmay Road. It is MOR’s understanding that the owners (Lyonara) intend for this bungalow to be demolished in the near future and the area to be used for car-parking, subject to obtaining the necessary planning consent. To the west the Site is bounded by a local road and by a vehicle dismantlers (Corcoran’s). To the south are two large buildings utilised by multiple commercial and industrial units, green fields (zoned enterprise &



employment) and a bungalow residence that shares a common boundary with the Site. Figure 1-2 illustrates the general context of the Site’s location.

Observations during site walk-overs indicated a diverse range of off-site acoustic emissions, both steady (louvres and chilling condenser units) and short term (hammering, forklift movements). Such emissions are typical of industrial areas such as the Clonminam Industrial Estate.

In line with the existing industrial and commercial nature of the locality, the green fields to the south are zoned ‘Enterprise & Employment’ within the Portlaoise Local Area Plan 2018-2024. The rail-line to the east is zoned as ‘Transport & Utilities’. Therefore, there is a low likelihood of new NSLs being developed in proximity to the Site.

Figure 1-2: Local Site Setting

Moving outward from the immediate vicinity of the Site boundary to the northeast is Portlaoise town centre (c.1.2km). The railway line serving the Dublin to Cork route is located to the west and northwest (c.0.35km). The Mountrath Road/R445 is located to the west (c.0.80km), and the Abbeyleix Road (c.075km) to the east. The M7 motorway (c.1km) is located to the south.



2 METHODOLOGY

All monitoring was conducted in strict accordance with best practice as outlined in NG4 (EPA, 2016d). Appendix A outlines the EPA NG4 Monitoring Checklist for the assessment and reporting for this project.

A glossary of terminology utilised within this report is also shown in Appendix A.

2.1 Competent Person

NG4 outlines the minimum criterion for a competent person (NG4 Section 2), stating that:

“All competent persons must possess a combination of technical knowledge, experience and skills, and must be able to demonstrate … both practical and theoretical competence and should participate in continual professional development. Competence may be demonstrated through reference to an appropriate qualification and/or professional membership of a recognised acoustic organisation (e.g. the Institute of Acoustics) and/or appropriate experience.”

The monitoring and analysis of the data was conducted by a MOR acoustician deemed to be a ‘competent person’ as per the criteria outlined within Section 2 of the NG4 Guidance Document. The monitoring programme, data and report were directed and reviewed by a full member of the Institute of Acoustics (MIOA) with over 14 years’ experience in environmental and acoustic consultancy.

2.2 Monitoring Locations

Locations for noise monitoring are referenced within IEL No P1028-01. Table 2-1 below describes each of the monitoring locations as illustrated in Figure 1-1.

The land to the west is occupied by industrial and commercial properties as the land is zoned for ‘Industrial & Warehousing’ use as per Portlaoise Local Area Plan 2018-2024. There are no observed NSRs to the west of the site boundary within 250m.

2.3 Measurement

The methodology followed was in accordance with the recommendation of:

• ISO 1996-1:2016 Acoustics – Description, measurement and assessment of environmental noise – Part 1: Basic quantities and assessment procedures, (ISO, 2016);



• ISO 1996-2:2017 Acoustics – Description, measurement and assessment of environmental noise – Part 2: Determination of environmental noise levels, (ISO, 2017); and,

• EPA Guidance Note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities (NG4) 2016, (EPA, 2016d).

In order to comply at each boundary monitoring location with Schedule C.4 of the Site IEL, three readings were taken during the daytime, one reading in the evening time and two readings during the night-time. Single measurements during each relevant time period were recorded at off-site locations.

Licence P1028-01 Schedule B.4 states that 30 minute readings are to be taken for day and evening periods. For night time periods, Schedule B.4 states that either 15 minute or 30 minute periods are required. A 15-minute monitoring period is typically deemed suitable for night time monitoring where facility activities are primarily steady emissions or internal activities. Based on previous monitoring at this Site by MOR, and the onsite opinion of the acoustician on the days of the monitoring event the 15 minute duration was utilised in this monitoring event.

In addition, real time 1/3 octave band frequency analysis was carried out at all monitoring locations during day, evening and night time monitoring periods. This data was utilised to evaluate objective tonality arising at each monitoring location, and the 1/3 octave charts are shown in Appendix B for each monitoring event.

At all sample locations the sound level meter (SLM) was positioned to maximise distance from reflective surfaces and mounted on a tripod to an approximate height of 1.2 to 1.5 meters over ground level.

To assist with the assessment of background noise arising from daytime road traffic, a summary of the Hourly LAeq data from an onsite continuous sound level meter, located near monitoring position NML1 (northern boundary) has been utilised. This SLM is an EM2030 units by Sonitus. The SLM is a Class 1 unit as per IED 61672 with a dynamic range of 20Hz to 20kHz. Details on the unit and calibration certification are presented in Appendix A.

2.4 Equipment

Attended noise measurements were carried out using a BRUEL & KJAER 2250 Hand-held Analyser SLM (Type 1/Class1), equipped with Frequency Analysis Software BZ7223. The monitoring equipment was calibrated prior to and post the measurement period using a BRUEL & KJAER sound level calibrator type 4231. Broadband noise levels were measured using the A-weighted network and a fast sampling interval, unless otherwise stated.

Laboratory calibration certificates for the BK 2250 SLM and the BK 4231 field calibrator are attached at Appendix C.

2.5 Frequency Analysis

Real time 1/3 octave band frequency analysis was carried out at each monitoring location, during both day, evening and night time monitoring events. The frequency spectra recorded at each of the monitoring events are attached at Appendix B.

Tones were objectively assessed in accordance with Section 5 of NG4. The standard states that:

“…for a prominent, discrete tone to be identified as present, the time-average sound pressure level in the one-third octave band of interest is required to exceed the time-average sound pressure levels of both adjacent one-third-octave bands by some constant level difference”.



The standard gives the level differences as follows:

• 15dB in the low-frequency one-third-octave bands (25Hz to 125 Hz);

• 8dB in the middle-frequency bands (160Hz to 400Hz); and,

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

In addition, the on-site acoustician noted any subjective tonality or defining characteristic arising from site specific noise emission sources, as per Section 5.1 of NG4.

2.6 Weather Conditions

As per Section 7.6 of NG4, the prevailing weather conditions at the time of measurement were noted and recorded in the survey report. A portable anemometer (Skywatch Explorer) was used to record wind speed before, during and after the noise survey periods.

Weather conditions on each of the monitoring dates were suitable, as per NG4, for conducting noise monitoring. During the January monitoring event conditions were cool, with slight drizzle recorded during the evening measurements. During the February monitoring event night-time conditions were cool and dry.

Onsite weather observations are supplemented by the closest Met Éireann weather station report (Carlow Oak Park, 31km southeast), shown in Table 2-2.

4 DISCUSSION

4.1 NML1

This noise monitoring location is positioned along the northern boundary c. 12m from the edge of Old Knockmay Road/Father Brown Avenue.

4.1.1 Day Time

Day time LAeq(30minute) measurements ranged from 67dB to 69dB. Traffic along the Old Knockmay Road/Father Brown Avenue was the dominant acoustic source (LA10(30minute) values of 70dB to 71dB), with an onsite 5 minute traffic count averaging 1 passing vehicle every 8 to 9 seconds.

Steady acoustic emissions (LA90(30minute) values of 56dB to 59dB) were attributed to offsite sources (industrial units to the north, east and west of the monitoring point) and the steady passage of traffic along Father Brown Avenue. During lulls in local noise sources, onsite activities (Intake Area, Grinder Area, Mill and Oat Mill buildings) were audible, though indistinct.

Traffic along the Old Knockmay Road/Father Brown Avenue was the dominant acoustic source. This monitoring point was also strongly influenced by offsite activities from Clonminam Industrial Estate. Table 3-4 shows the LAeq, LA90 and LA10 taken over 1 hour periods on the northern boundary. The table shows the negligible acoustic impact from a complete Site wide shut-down on the northern boundary, with no discernible variation in the LAeq or LA10 values, and a potential 1dB to 2dB change in LA90. The impact on this boundary from onsite activities was negligible during the survey.

4.1.2 Evening Time

Traffic along the Old Knockmay Road/Father Brown Avenue was the dominant acoustic source. This monitoring point is also influenced by offsite activities from Clonminam Industrial Estate.

The Grinder/Intake area emissions were audible in the background at times, along with vehicle movements in/out of the Site.

The LA90(30minute), though still strongly influenced by off-site steady sources would give an indication of compliance. The LA90(30minute), at NML1 was 49dB, compliant with the licence limit, though mostly influenced from off-site sources.

4.1.3 Night Time

Traffic along the Old Knockmay Road/Father Brown Avenue was the dominant acoustic source. This monitoring point is also influenced by offsite activities from Clonminam Industrial Estate.

Similar to the evening period, noise arising from the Grinder and Intake area of the Site were audible at times, though typically masked by off-site emissions.

The LA90(15minute), though still strongly influenced by off-site steady sources would give an indication of compliance. The LA90(15minute), at NML1 was 46dB, at both 23:46 and 01:25. Though 1 dB above the limit, the Site-specific component to this value, is less dominant than off-site sources. Utilising the standard equations for the addition of noise values (𝐿 = 10 ∗

𝐿𝑜𝑔10(∑ 10(𝐿𝑖

10))∩

𝑖=1 ) the Site-specific emission at this boundary was less than 43dB.

4.2 NML2

Located on the western boundary, the Oat Mill building is c.70m to the north, the Mill building is c.125m east.



4.2.1 Day Time

Day time LAeq(30minute) measurements was 56dB for all three runs. Steady acoustic emissions (LA90(30minute) values of 54dB to 55dB) were attributed to onsite activities (Oat Mill and Mill buildings, compressor room and truck wash) and offsite (louvres from Corcoran’s, vehicle movements).

Utilising LA90(30minute) values to discount traffic and offsite activities the Site is compliant with the day time limit (LAR,T 55dB).

4.2.2 Evening Time

Steady acoustic emissions (LA90(30minute) of 51dB) from the Mill and Oat Mill buildings and compressor room decreased by c.3dB to 4dB compared to the day time event.

Utilising LA90(30minute) values to discount traffic and subtracting 2dB to 3dB for offsite activities (refer to section 4.1.3) the Site is compliant with the evening time limit (LAR,T 50dB).

4.2.3 Night Time

The night time LAeq(15minute) results ranged from 46dB to 47dB. Onsite emissions include mill vents and cooler fans, all steady emissions. Off-site emissions included the passing of traffic on Knockmay Road/Fr. Brown Avenue (peak events) reversing alarms within Clonminam and the steady background hum of traffic in the distance.

Due to local traffic noise and external influences, the LA90(15minute) (ranging from 44dB to 45dB) values are deemed to be more representative for the purpose of assessing site specific noise, and reducing influence of external influences, such as traffic. The Site is therefore compliant with the night time limit (LAeq,T 45dB).

4.3 NML3

Located on the southern boundary this location is a proxy for the Southern NSR more than 10m south of this monitoring location.

4.3.1 Day Time

Day time LAeq(30minute) measurements ranged from 52dB to 53dB for three runs. Steady acoustic emissions (LA90(30minute) values of 49dB to 52dB) were attributed to a mix of onsite activities (Oat Mill and Mill buildings, truck wash and power washing) and offsite (vehicle movements, activities in Corcoran’s yard).

Utilising LA90(30minute) values to discount traffic and offsite activities the Site is compliant with the day time limit (LAR,T 55dB).

4.3.2 Evening Time

Evening time LAeq(30minute) measurement was 52dB. Steady acoustic emissions (LA90(30minute)

values of 51dB) were attributed to a mix of onsite activities (Oat Mill and Mill buildings, truck wash) and offsite sources (vehicle movements, activities in Corcoran’s yard).

Utilising LA90,30minute values to discount traffic and subtracting 2dB to 3dB for offsite activities influence (refer to Section 4.1.3) the Site is compliant with the evening time limit (LAR,T 50dB).

4.3.3 Night Time

The night time LAeq(15minute) results ranged from 46dB to 47dB. The steady acoustic emissions (LA90(15minute) 44dB) value for both runs decreased compared to the day and evening time events.



Due to traffic noise and external influences LA90(15minute) values are deemed to be more representative for the purpose of assessing site specific noise and reducing external influences. The Site is therefore compliant with the night time limit (LAeq,T 45dB).

4.4 NML4

Located on the eastern boundary c. 100m south of the Intake Area this location is a proxy for noise emissions at the Site boundary that could potentially impact the dwellings within Abbey Court.

4.4.1 Day Time

Day time LAeq(30minute) measurements ranged from 52dB to 54dB for three runs. Steady acoustic emissions (LA90(30minute) values of 49dB to 51dB) were attributed to onsite activities (Mill building, Intake Area, Grinder Area, truck wash and power washing). Distant traffic was also audible.

Utilising LA90(30minute) values to discount off-site short duration influences, the Site is compliant with the day time limit (LAR,T 55dB).

4.4.2 Evening Time

Evening time LAeq(30minute) measurement was 50dB. Steady acoustic emissions (LA90(30minute)

values of 48dB) were attributed to the Mill building, Intake Area and Grinder Area.

Utilising LA90(30minute) values to discount off-site short duration influences the Site is compliant with the evening time limit (LAR,T 50dB).

4.4.3 Night Time

The night time LAeq(15minute) results ranged from 46dB to 48dB. The steady acoustic emissions (LA90(15minute) 43dB to 44dB) value for both runs decreased compared to the day and evening time events.

Due to traffic noise and external influences LA90(15minute) values are deemed to be more representative for the purpose of assessing site specific noise and reducing external influences, such as traffic. The Site is therefore compliant with the night time limit (LAeq,T 45dB).

4.5 Background

Continuous monitoring of noise is shown in Graph 3-1 (northern boundary ambient) emphases the diurnal (day peak, night trough) of the recorded data. This trend is emphasised over the longer term in Graph 3-2. The diurnal changes are typical of human activity dominated areas the daytime LA10 and LAeq show strong correlation, which is typical of steady road traffic. During the night, the ‘spikey’ nature of the LA10 and LAeq are typical of occasional traffic movements. The LA90 values follow the general trend during the day, while at night the correlation is not as definitive. This is typical where the relatively steady daytime traffic affects the LA90 parameter, while during the night, with the fall off in traffic the LA90 becomes dominated by general emissions in the locality.

The Site operates with relatively little change between day and night, with the exception of additional administration and site maintenance workers during the day.

To assess the level of impact the Site has on the local ambient acoustic environment, a 1 hour shut down occurred on 23rd January 2019. The values prior to, during and post shut down are included in Table 3-4. Notably the values taken along the northern boundary show no detectable change for acoustic parameters of LAeq,1hour, LA10,1hour and only a 1dB to 2dB for the LA90,1hour value. This test, on the day it was conducted, indicated that Site specific noise is generally not clearly audible on the northern boundary, and is, at most, a secondary contributor to LA90 background values.



4.6 Noise Sensitive Location

The monitoring in Abbey Court was predominantly influenced by traffic (LA10,T). The Site was subjectively inaudible throughout the monitoring period. The dominant noise source was traffic on the Abbeyleix Road, vehicles entering/exiting the housing estate and the service station. In addition, the car wash compressor at the nearby service station was a dominant noise source at this location. Reversing alarms to the northwest associated with HGVs were audible during the monitoring period and distinguished as arising from the An Post facility during the night-time monitoring event.

During the monitoring events at Abbey Court, impacts from the Site were minimal, and always masked by local ambient noise sources.

4.7 Objective Tonality Discussion

No objective tones were identified as per NG4 during day, evening and night time monitoring with the exception of NML3 Night Run 1. An LZeq 2.5kHz tone was identified which was associated with an offsite alarm siren to the west of the Site. No objective tones associated with the Site were identified during monitoring. Therefore, no weightings for tonality are required to the recorded values.

4.8 Site Specific Compliance

In the context of IE Licence Reg No. P1028-01, the fact remains that the receiving background acoustic environment is dominated by offsite traffic noise (Old Knockmay Road/Father Brown Avenue and M7 motorway) and industrial activities to the north, east, south and west of the Site. This is factually supported by noise monitoring data compiled at boundary locations when the Site was not operational and through monitoring at off-site positions.

Utilising LA90,T values as per the NG4 Guidance and using standard logarithmic equations the Site is compliant with the day, evening and night criteria for boundaries, where Site specific noise emissions were clearly discernible.

4.9 Comparison to Historic

Historic compliance monitoring detailed in Table 3-5 illustrates the acoustic improvements made at the Site since 2017.

At locations where Site specific emissions were dominant, improvements of over 4dB have been recorded. Minimal to no change has been recorded where the dominant acoustic source is off-site.



5 CONCLUSIONS

The conclusions are based on the findings of the noise assessment survey that was undertaken in strict compliance with the following EPA-stipulated requirements:

“The licensee shall conduct a noise assessment survey in accordance with the methodology specified in NG4 and as per Condition 6.14 & Schedule C.4 of the license.

… The noise assessment survey report shall be submitted via monitoring licensee return on the EDEN Portal by 04th March 2019.”

Noise monitoring was undertaken at four boundary locations in strict accordance with Schedule B.4 and C.4 of the Licence and as per NG4.

Additional monitoring was also conducted within the Clonminam Industrial Estate (for background values) and at the eastern Noise Sensitive Receptor (Abbey Court).

All monitoring was undertaken by competent MOR Acousticians in strict compliance with the NG4 Guidance.

Results from a continuous noise monitor on the northern boundary, have also been incorporated into this report to provide additional data to outline the high background noise levels in the locality.

The results of this noise assessment confirm that noise emissions arising from the Site are compliant with the limits stipulated in IEL No. P1028-01 that was issued by the EPA to Glanbia Foods Ireland Ltd on the 1st August 2017.

No site specific tonal or impulsive components were recorded at boundary or off-site monitoring positions in compliance with the limits stipulated in IEL No. P1028-01.

Noise levels at Noise Sensitive Locations (i.e. residential houses) were compliant with the limits specified in the EPA’s NG4 Guidance Document.

The results of this survey confirm that the significant investment, in the region of €400,000, that Glanbia have proactively made in implementing noise mitigation measures since the last noise survey have proven to be successful.

The results also reaffirm the fact that the receiving ambient acoustic environment is dominated by offsite traffic noise (Old Knockmay Road/Father Brown Avenue and M7 motorway), the railway line and industrial activities to the north, east, south and west of the Site.

The offsite measurements at the Abbey Court NSR confirmed that this location was not influenced by Site noise emissions. This is not surprising as it can be demonstrated that, given the distance (c.830m) that separates the Site from this NSR and the influence of background noise levels.

We trust that this report should satisfy the EPA that sufficient works have now been undertaken in regards to the Open Compliance Investigation into Noise Complaints and Noise Levels (CI001581).

Glossary of Acoustic Terminology

Abbreviation / Description Descriptor

A Weighted A time weighting given to noise values to amend the values to suit the human ear response to the various frequency components of the sound.

Acoustic environment Sound from all sound sources as modified by the environment (BS ISO 12913-1:2013).

Ambient sound

Totally encompassing sound in a given situation at a given time, usually composed of sound from many sources, near and far. Note: The ambient sound comprises the residual sound and the specific sound when present.

Ambient sound level, La = LAeq, T

Equivalent continuous A-weighted sound pressure level of the totally encompassing sound in a given situation at a given time, usually from many sources near and far, at the assessment location over a given time interval, T. Note: the ambient sound level is a measure of the residual sound and the specific sound when present.

Background sound level, LA90, T

A-weighted sound pressure level that is exceeded by the residual sound at the assessment location for 90% of a given time interval, T, measured using time weighting F and quoted to the nearest whole number of decibels.

dB (decibel) A relative unit of measurements, based on a logarithmic scale to describe the ratio between the measured level and a reference or threshold level of 0dB. Unless otherwise stated 0dB within this report is 2x10-5 pascals (Pa).

Day A 24 hour period from midnight to midnight.

Daytime A 12 hour period between 07:00 – 19:00 hours, as per NG4

Evening-Time A 4 hour period between 19:00 – 23:00 hours, as per NG4

Equivalent continuous A-weighted sound pressure level, LAeq, T

Value of the A-weighted sound pressure level in decibels of continuous steady sound that, within a specified time interval, T=t2-t1, has the same mean-squared sound pressure as a sound that varies with time, and is given the following equation:

where: p0 is the reference sound pressure (20 µPa); and pA(t) is the instantaneous A-weighted sound pressure (Pa) at time t Note: The equivalent continuous A-weighted sound pressure level is quoted to the nearest whole number of decibels.

LAN,T The Fast interval, A-Weighted noise level in the for the ‘N’ percentile of the

sampling interval 'T'.

LA10,T The A-Weighted noise level for the 10%ile of the sampling interval ‘T’, typically utilised to represent peak noise events such as intermittent passing traffic.

LA90,T The A-Weighted noise level in the lower 90 percentile of the sampling interval 'T', excludes intermittent features typical of traffic. See also background sound level.

LA95,T The A-Weighted noise level for the 95%ile of the sampling interval ‘T’. Representative of steady noise events at a monitoring location.

LAeq,T The equivalent continuous sound level, used to describe the fluctuating noise in terms of a single noise level over the same sampling time period (T). Also see ambient sound.

Lden Day-evening-night equivalent level, calculated as:

Where the Lday, Levening and Lnight are as defined in ISO1996-2:1987, and for the duration of 12 hours, 4 hours and 8 hours respectively, are A-weighted long term Leq sound level.

Lday Day equivalent level. A-weighted Leq sound level measured over the 12 hour period from 07:00 hours to 19:00 hours.

Levening Evening equivalent level. A-weighted Leq sound level measured during the evening period of 19:00 hours to 23:00 hours.

LAmax The maximum RMS A-Weighted sound pressure level occurring within a specified time period.

Lnight Night equivalent level. A-weighted Leq sound level measured during the night period of 23:00 hours to 07:00 hours.

Measurement time interval, Tm

total time over which measurements are taken. Note: This may consist of the sum of a number of non-contiguous, short-term measurement time intervals.

Rating level, LAr, Tr specific sound level plus any adjustment for the characteristic features of the sound.

Residual sound ambient sound remaining at the assessment location when the specific sound source is suppressed to such a degree that it does not contribute to the ambient sound.

Residual sound level, Lr = LAeq,T

equivalent continuous A-weighted sound pressure level of the residual sound at the assessment location over a given time interval, T.

Specific sound level, Ls = LAeq,Tr

equivalent continuous A-weighted sound pressure level produced by the specific sound source at the assessment location over a given reference time interval, Tr.

Specific sound source sound source being assessed.

Night-Time An 8 hour period between 23:00 – 07:00 hours, as per NG4

Noise Ambient The totally encompassing sound in a given situation at a given time, usually composed of sound from many sources, near and far. Also see ambient sound.

Noise Background

The steady existing noise level present without contribution from any intermittent sources, The A-weighted sound pressure level of the residual noise at the assessment position that is exceeded for 90 per cent of a given time interval, 'T' (LAF90,T). Also see background sound level, LA90, T.

Noise Specific The sound arising from the source under investigation, disregarding all external and residual sources. Also see specific sound source.

NSR Noise Sensitive Receptor - an identified dwelling, amenity area, recreational zone or other such place where a change in noise may result in a nuisance impact.

RMS Root Mean Squared, mathematical method to account for swells and troughs within wave forms, such as sound.

Sound Power Level (LW)

The logarithmic measure of sound power in comparison to a referenced sound intensity level of one picowatt (1pW) per m2. Utilised to express the intensity at source of a noise emission.

Sound Pressure Level (LP)

Fluctuations in air pressure caused by the passage of a sound wave. The measurement of sound/noise through the use of a sound level meter, is a representation of these fluctuations in air pressure as they pass the instrument microphone.

Time Weighting One of the averaging time for noise monitoring instrumentation: F – Fast, instrument samples every 125 milliseconds; S – Slow, instrument samples every 1 second; I – Impulsive, instrument samples every 35 milliseconds.

Note:

Unless otherwise stated all broadband noise values are A-weighted with a fast response. Where 0dB is referenced it refers to the threshold of hearing – 2x10-5Pa. All 1/3 octave values are unweighted/linear. (z-weighted on the Bruel and Kjaer software)
