EXECUTIVE SUMMARY
BnM Environmental was commissioned by Mr. Gabriel McCann of Proctor & Gamble (Manufacturing)
Ireland Ltd, in relation to carrying out an environmental noise assessment within the vicinity of the
Newbridge facility in compliance with the requirements of their IPPC Licence (P0297-02).
Triplicate daytime and duplicate night-time noise monitoring was conducted at four boundary locations
and three noise sensitive locations for 15 minute intervals, on the 5th and 6th December 2017. The
acoustic assessment and report are in accordance with International Standard Organisation (ISO)
1996 Acoustics –Part 1, 2, and 3 in addition to the Environmental Protection Agency 2012, “Guidance
note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities
(NG4) 2016”.
Condition 8.3 of IPPC Licence P0297-02 states that ‘’Activities on-site shall not give rise to noise levels
off-site, at noise sensitive locations, which exceed the following sound pressure limits (Leq,15
minutes) subject to Condition 3 of this licence:
8.3.1 Daytime: 55 dB(A)
8.3.2 Night-time: 45 dB(A).’’
Condition 3.4.1 ‘’Noise from the activity shall not give rise to sound pressure levels (Leq,15 minutes)
measured at the specified noise sensitive locations which exceed the limit value(s) by more than 2
dB(A).’’
DAY-TIME
Daytime noise measurements (LAeq15mins) at locations AN1A - AN3A ranged from 60 – 63 dB(A). The
predicted specific noise levels at the NSL’s closet to these locations ranged from 55 – 58 dB(A).
The specific noise levels at all noise sensitive locations were compliant with the Licence limits for day-
time noise subject to condition 3.4.1 with the exception of AN2A (58 dB(A)). The dominant source of
noise was attributed to heavy road traffic on the Adjacent M7 motorway and contributed largely to
noise levels. The wind on the day was from a north westerly direction.
There was no clear tonal or impulsive component due to site activity present at any of the noise
sensitive locations.
NIGHT-TIME
Night-time noise measurements (LAeq15mins) at locations AN1A - AN3A ranged from 56 – 59 dB(A). The
predicted specific noise levels at the NSL’s closet to these locations ranged from 42 – 50 dB(A).
The specific noise levels at all noise sensitive locations were compliant with the Licence limits for
night-time noise subject to condition 3.4.1 with the exception of AN2A (50 dB(A)). The dominant
source of noise was attributed to heavy road traffic on the Adjacent M7 motorway and contributed
largely to noise levels. Onsite noise included the continuous hum from dust extractors and the faint
hissing noise coming from dryer house.

1.0 INTRODUCTION
The Newbridge based Proctor & Gamble (Manufacturing) Ireland Ltd, facility is licensed by the
Environmental Protection Agency (EPA) under Integrated Pollution Prevention and Control
(IPPC) number PO297-02. The site is located approximately 2.2km directly south of
Newbridge town centre, within the IDA Industrial estate (see Figure 1).
Figure 1 – Location of P&G facility
The facility is bounded by agricultural lands to the East, Industrial to the North, residential to
the West. The Southern perimeter of the facility partially bounds the M7 motorway.
In compliance with IPPC Licence P0297-02, P&G are required to conduct annual noise
monitoring at the site for submission to the agency as part of their Annual Environmental
Review (AER).
BnM Environmental was commissioned to conduct the annual noise survey. An Acoustic
Consultant from BnM Environmental subsequently visited the site on the 5th & 6th December
2017. The survey consisted of measurements representative of noise levels at four boundary
locations and at 3 on-site locations to best represent sound emissions to the nearest noise
sensitive locations by day and by night.
This report details the sampling and analytical methodologies employed and also includes a
broad interpretation of the results obtained.

2.0 NOISE CRITERIA
In compliance with the requirements of Condition 9 (Noise) of IPPC Licence P0297-02,
Proctor & Gamble (Manufacturing) Ireland Ltd is obliged to;
Condition 8.1 - The licensee shall carry out a noise survey of the site operations annually
Condition 8.3 - Activities on-site shall not give rise to noise levels off-site, at noise sensitive
locations, which exceed the following sound pressure limits (Leq, 15 minutes) subject to
Condition 3 of this licence:
8.3.1 Daytime: Until 2nd May 2000: 60 dB(A)
Thereafter: 55 dB(A)
8.3.2 Night-time: Until 2nd May 2000: 50 dB(A)
Thereafter: 45 dB(A)
Condition 8.4 - There shall be no clearly audible tonal component or impulsive component in
the noise emission from the activity at any noise sensitive location.
3.4 Noise
3.4.1 Noise from the activity shall not give rise to sound pressure levels (Leq,15 minutes)
measured at the specified noise sensitive locations which exceed the limit value(s) by more
than 2 dB(A).
The survey should be undertaken in accordance with the methodology specified in the
‘‘Environmental Noise Survey guidance Document’’ as published by the Agency’’.
3.0 METHODOLOGY
3.1 Measurement Parameters
3.1.1 LAeq Values
LAeq (t) values represent the continuous equivalent sound level over a specified time (t) in the
A weighted scale. This value expresses the average levels over time and is a linear integral.
3.1.2 LAMax Values
The maximum RMS, A-Weighted sound pressure level occurring within a specified time
period.
3.1.3 LA90 and LA10 Values
The LA90 and LA10 values represent the A-weighted sound levels exceeded for a percentage
of the instrument measuring time. LA10 indicates that for 10% of the monitoring period, the
sound levels were greater than the quoted value. LA10 is a good statistical parameter for
expressing event noise such as passing traffic. The LA90 represents post event sound levels
and is a good indicator of background noise levels.

3.2 Tonal and Impulsive Characteristics
For the purpose of this report, tonal noise is characterised in accordance with Section 5.1 of
the EPA’s NG4 document, which indicates that a noise source is tonal if a 1/3 octave band
exceeds adjacent bands by;
· 15dB in low/frequency 1/3 octave bands (25Hz to 125Hz);
· 8dB in middle/frequency bands (160Hz to 400Hz), and;
· 5dB in high/frequency bands (500Hz to 10,000Hz).
An impulsive noise is of short duration (typically less than one second), it is brief and abrupt,
its’ startling effect causes greater annoyance than would be expected from a simple
measurement of sound pressure level. For example an instantaneous bang/thud that maybe
associated with pile driving, hammering etc.
3.3 Standards and Guidance
The acoustic assessment and subsequent report are in accordance with International
Standard Organisation (ISO) 1996 Acoustics – Description and Measurement of
Environmental Noise Part 1, 2, and 3, in addition to the Environmental Protection Agency
Environmental Noise Survey Guidance Document Revision 4 (NG4) 2016.
3.4 Site information
2.4.1 All measurements were taken at 1.2 -1.5 m height above local ground level and at least 3.5m
away from reflective surfaces other than the ground.
3.4.2 The weather was dry and calm, with a wind-speed of <5ms/sec at the time of the assessment.
3.4.3 Table 2.1 describes the locations of the monitoring positions for the noise survey.
3.4.4 Triplicate noise measurements were obtained at each sampling location during daytime hours
and duplicate measurements during night-time hours, for a minimum time period of 15
minutes, in accordance with the EPA Noise Guidance 4 document
3.4.5 Sampling Locations are presented in Table 3.1 overleaf (Please refer to map included in
Appendix I).

Noise monitoring was conducted in accordance with International Standard Organisation (ISO)
1996 Acoustics – Description and Measurement of Environmental Noise Part 1, 2, and 3 in
addition to the Environmental Protection Agency Environmental Noise Survey Guidance
Document (NG4) at each of the four boundary locations (BN1-BN4) and three Noise Sensitive
Locations (AN1A-AN3A).
Section 7.8 of the EPA’s NG4 document describes methods for estimating the specific noise level
(LART). For the purposes of this report this report the following approach was adopted to determine
the site specific noise;
Boundary Location
The CRTN method for assessing road traffic describes the L10 value as being most representative
value for road traffic noise, which has since become the ‘de facto’ measurement index for
describing road traffic noise. Considering that the road traffic was the dominant source (LA10
values) it is therefore reasonable to assume that the residual noise was due to operations within
the P&G facility (LA90 values) and may therefore be referred to as the specific noise.
Noise Sensitive Locations
The NG4 document states that ‘‘…for facilities that operate continuously for 24 hours, it may be
appropriate to measure at a time when all (or most) other noises have subsided. This will often
mean measuring late at night when general traffic noise has reduced. Where noise output from
the facility can be temporarily eliminated or subdued, it may be possible to estimate the facility’s
specific noise level by measuring the noise level with and without the facility running’’.
This method was adopted to determine the specific noise at these locations. All noise sources
were shut down at the facility for 1 hour to determine the residual noise at these locations.
Specific Noise = Ambient Noise – Residual Noise

5.1.1 SITE BOUNDARY DISCUSSION
BN1
Monitoring station BN1 is at the Eastern corner of the facility, just behind the car-park. This
location has a clear view of the facility and associated auxiliary equipment along the Eastern
gable of the main building (see Plate 1)
.
Plate 1 – BN1
As can be seen from Tables 5.2 and 5.3, the resultant SPL’s were 58 - 65 dB(A) daytime and 53
dB(A) night-time during both measurements. Road traffic on the adjacent M7 motorway was
continuous and dominance. Audible on-site activity included; dust extractor/water chiller being
faintly audible at times during the day and audible at night-time.

BN2
Monitoring location BN2 is located along a raised grass embankment at the Southern corner of
the P&G facility. This monitoring station has a partial view of the P&G facility (seen Plate 2).
Plate 2 – BN2
As can be seen from Tables 5.2 and 5.3, the resultant SPL’s ranged from 66 - 67 dB(A) during
the daytime and 6 dB(A) during the night-time hours. On site field notes showed that passing
traffic on the M7 motorway was the dominant noise source during the day/night time monitoring.
The only source of on-site noise was due to the air extraction fans, which were occasionally faintly
audible during the daytime events in the absence of M7 traffic. During night-time events the air
extractor fans were faintly audible according to field notes.

BN3
Monitoring location BN3 is located along a raised grass embankment, at the Western corner of
the facility (see Plate 3).
Plate 3 – BN3
As can be seen from Tables 5.2 and 5.3, the resultant SPL’s for day-time noise was 59 dB(A) for
all daytime measurements and 56/60 dB(A) during the night-time hours. On site field notes
showed that passing traffic on the M7 motorway was the dominant noise source during the
day/night time monitoring events.
The only source of on-site noise was a continuous low level hum from the dust extractor and
compressor which was occasionally audible during the day. The audibility of the dust extractor
and compressor was more prominent during night-time and low levels of passing traffic on the M7
motorway.

BN4
Monitoring location BN4 is located within the North-West car-park, in front of fire assembly point A
(see Plate 4 below).
Plate 4 – BN4
As can be seen from Tables 5.2 and 5.3, the resultant SPL’s for day-time noise was 60 dB(A) on
all daytime measurements. The night-time SPL’s was 51 dB(A) respectively. On site field notes
showed that occasional passing traffic on the IDA entrance Rd. (20m) and passing traffic on the
Green Road were the dominant sources of noise during the day-time monitoring event and
included the slowing and subsequent revving of vehicles passing over the speed ramp. During the
night-time monitoring event the dominant source of noise was due to road traffic on the M7 (low
level) and occasionally Green Rd. Audible site activity included dust extractor/compressor faint
audibility during daytime events and dryer room during the night-time event.

4.2.1 NOISE SENSITIVE LOCATION DISCUSSION
AN1A (27 Meters from residential dwelling along North-West boundary)
Monitoring station AN1A is located along the North-West boundary, beside the air cooled
condenser units. This location was chosen to best represent sound emissions to an occupied
residential dwelling; situated 27 meters North-West of this monitoring station (see Plate 5).
Plate 5 – AN1A
As can be seen from Tables 5.4 and 5.5, the resultant SPL’s were 60 – 62 dB(A) daytime and 58
dB(A) night-time. On site field notes showed that passing traffic on the M7 motorway was the
dominant noise source of off-site noise during the day/night time monitoring events. During both
day and night time events the dryers, extractors and compressors were audible.
To determine the predicted sound pressure levels to the nearest NSL, and to determine the
compliance status with IPPC licence P0297-02, please refer to Section 5.2.2 (Predicted SPL at
nearest NSL).

AN2A
Monitoring location AN2A is located along a raised grass embankment, along the South-West
perimeter the facility (see Plate 6).
Plate 6 – AN2A
This location was chosen to best represent sound emissions to the nearest residential dwelling;
situated approximately 20 meters South-West of this monitoring station, within the Grange Heights
housing estate.
As can be seen from Tables 5.4 and 5.5, the resultant SPL’s for day-time noise ranged from 61 -
62 dB(A). The night-time SPL’s recordings were 56/57 dB(A). On site field notes showed that
passing traffic on the M7 motorway and traffic on the adjacent Green Rd. were the dominant
noise source during the day/night time monitoring events. Sources of on-site noise included the
faint hissing noise from the dryer room and the continuous low level hum from the dust extractor
which was audible during night time events during periods of low passing traffic on the M7.
To determine the predicted sound pressure levels to the nearest NSL, and to determine the
compliance status with IPPC licence P0297-02, please refer to Section 5.2.2 (Predicted SPL at
nearest NSL).

AN3A (Located along grass embankment on Southern boundary to represent emissions to
residents at Grange View).
Monitoring location AN3A is located along a raised grass embankment, along the Southern
perimeter the facility (see Plate 7).
Plate 7 – AN3A
This location was chosen to best represent sound emissions to the nearest residential dwelling;
situated approximately 20 meters West of this monitoring station, within the Grange View housing
estate.
As can be seen from Tables 5.4 and 5.5, the resultant SPL’s ranged from 62 - 63 dB(A) during
the day-time and 58/60 dB(A) during the night-time. On site field notes showed that passing traffic
on the M7 motorway (60m to nearside carriageway) was the dominant sources of noise in both
the daytime and night-time monitoring events.
To determine the predicted sound pressure levels to the nearest NSL, and to determine the
compliance status with IPPC licence P0297-02, please refer to Section 5.2.2 (Predicted SPL at

5.2.2 PREDICTED SPL AT THE NEAREST NSL’S
Condition 8.3 of IPC Licence P0297-02 states that ‘’Activities on-site shall not give rise to noise
levels off-site, at noise sensitive locations, which exceed the following sound pressure limits
(Leq,15 minutes) subject to Condition 3 of this licence:
8.3.1 Daytime: 55 dB(A)
8.3.2 Night-time: 45 dB(A).’’
Condition 3.4.1 ‘’Noise from the activity shall not give rise to sound pressure levels (Leq,15
minutes) measured at the specified noise sensitive locations which exceed the limit value(s) by
more than 2 dB(A).’’
It order to establish compliance with these conditions, the following approach has been employed;
Step 1 – Establish ambient SPL on site at 3 on-site locations (AN1A-AN3A) during typical daytime
and night-time hours.
Step 2 – Establish the residual SPL on site at 3 onsite locations (AN1A-AN3A) during typical daytime
and night-time hours when the all noise sources within the P&G facility are shut down.
Step 3 – Establish the specific SPL on site at 3 onsite locations (AN1A-AN3A) during typical daytime
and night-time hours by subtracting the residual noise from the ambient noise at each
location. Specific Noise = Ambient Noise – Residual Noise
Step 4 – Use the known specific noise at the 3 on-site locations to extrapolate the SPL at the
nearest noise sensitive locations. The following methodology is employed;
In order to represent the worst case scenario the highest specific noise established for each
location (AN1A - AN3A) during the day/night is taken to be the noise emission exclusively due to
activity within the P&G facility during these times. It is also worth noting that the topography of the
landscape is undulating, with a 7 foot soil berm between the source and receiver. All measurements
were conducted on-top of this soil berm to represent the worst possible scenario (I.e. a direct line of
sight from source to receiver). There is also some soft grassland and some mature deciduous trees
along the site boundary, which are not taken into consideration for the purposes of this calculation.
To predict the noise level at the nearest NSL’s due to activity within P&G, the reference sound
pressure level at known distance (R1) was determined. This reference pressure level at R1 is
then used to determine the SPL at a given distance R2 to represent the SPL at the nearest NSL’s.
Predictions shall be carried out by employing the inverse square law, which is a “rule-of-thumb”
used to calculate the expected reduction in noise levels as one moves away from the source.
Generally, as one doubles the distance from the source, a reduction of 6 dB is expected. Within a
confined space however, this rule does not apply due to reflection, where a diffuse field is set up
at a level higher than that expected from this law.
The Inverse Square law is defined as.
Lp2 = Lp1 - 20 Log (R2/R1) where:
Lp2 is the calculated sound pressure level at R2 meters towards the receiver location
(NSL).
Lp1 is the measured reference sound pressure level at R1 meters from P&G

5.3 Tonal Noise Assessment
For the purpose of this report, tonal noise is characterised in accordance with Section 5.1 of the
EPA’s NG4 document, which indicates that a noise source is tonal if a 1/3 octave band exceeds
adjacent bands by;
· 15dB in low/frequency 1/3 octave bands (25Hz to 125Hz);
· 8dB in middle/frequency bands (160Hz to 400Hz), and;
· 5dB in high/frequency bands (500Hz to 10,000Hz).
A desktop analysis of the spectral content for each monitoring location was conducted. It was
found that there was no tonal noise present during the daytime or night-time monitoring location.
The frequency graphs for each noise sensitive location are presented in Appendix III of this
report. Frequency graphs for the four boundary monitoring locations are available upon request.
5.4 Assessment of on-site Noise Sources
In order to determine the sound power level (Lw) of the principal environmental noise, associated
with activity within the P&G facility, noise measurements were conducted at 5 pieces of equipment at
a reference distance of 1 meter. The results of the assessment are presented in tabular format
below.
