1. INTRODUCTION

Noise monitoring was carried out at Padraig Thornton Waste Disposal Ltd (PTWDL) T/A Thorntons Recycling, Dunboyne Civic Amenity and Materials Recycling Facility at NP1, NP3, and NP6 (logging) on the 28th June 2016. Due to weather conditions NP2, NP4, NP5, and NP6 (frequency) were monitored on the 29fh June 2016. Noise monitoring was undertaken by Sandra Kiely of Thorntons Recycling Environmental Department. Staff have been trained with Bruel and Kjaer in noise monitoring and monitoring was carried out in compliance with Condition 6.10.1 of the licence (WO206-01).

The land use in the immediate vicinity of the facility comprises of a mixture of agricultural land, commercial, retail, light industrial activities in the industrial estate and residential. The residential areas are located 200m and further of the facility to the South West. There is also a bypass road connecting to the main M3 motorway along the Eastern side of the facility.

2. SCOPE

The scope of the project was to undertake a noise survey as stipulated in Condition 6.10.1 of the waste licence, which states that, “The licensee shall carry out a noise survey of the site operations bi-annually. The survey programme shall be undertaken in accordance with the methodology specified in the ‘Environmental Noise Survey Document’ as published by the Agency’ and Schedule B of the licence. Schedule B stipulates that the maximum daytime (Monday to Friday) dB LAeq (30 minutes) shall not exceed 55dB and that on Saturdays and night time the dB LAeq (15 minutes) shall not exceed 45dB. Schedule B also stipulates that there shall be no clearly audible tonal component or impulsive component in the noise emissions from the activity at any noise sensitive location. The noise criteria outlined above is applicable at the two noise sensitive locations N5 and N6 only. Noise recording at the boundary locations is compared to the guideline level for comparison levels only.

Monitoring Locations

Noise monitoring was undertaken at six locations. These locations are illustrated in Appendix A. Noise monitoring point NI is located on the Eastern boundary, N2 on the Southern boundary, N3 on the Northern boundary and N4 on the Western boundary. Noise emissions are recorded at these locations to determine the noise levels at the boundary of the facility during day time operations. The two remaining noise monitoring points are N5, which is located in a housing estate South West of the site and N6 which is located along a third class road South East of the site. Noise emissions are recorded at both N5 and N6 to determine the impact of noise from the facility at these noise sensitive locations.

Monitoring Frequency

Monitoring is to be carried out bi-annually using methodology specified in the Environmental Noise Survey Document as published by the EPA and revised in 2012 (Guidance Note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities (NG4)). This was reduced to annually for 2015 upon agreement with the EPA. This includes measuring the following parameters:

a- L (A)eq (30 minutes) b- L ( A ) ~ o (30 minutes) c- L ( A ) ~ o (30 minutes) d- Frequency Analysis (U3 octave band analysis)

Survey Instrumentation and Methodology

In all cases the sound level metre (SLM) was mounted on a tripod 1.5 metre above the ground level and at least 3.5 metres away from any sound reflecting objects. A wind shield was placed on the microphone to reduce any wind interference during measurements. Measurements were carried out on a calm day in between periods of light- moderate rain. The sound meter was orientated toward the noise sources for all measurements and the area in between the sound level metre and the noise source was free from any temporary obstacles.

The measurements were made using a Bruel & Kjaer 2238 mediator sound meter. The instrument was calibrated by Bruel & Kjaer on the 02nd June 2016 and it was also calibrated in situ at 94dB prior to and after the measurement period using a Bruel & Kjaer 423 1 acoustic calibrator. The acoustic calibrator was calibrated by Bruel and Kjaer on the 2Sh May 20 16.

The primary measurement parameter was the equivalent continuous A- Weighted Sound Pressure Level, LAeq 30, as recommended by the EPA Guidance Note for Noise document (2012). The LAeq 30 is the average level recorded over 30 minutes. The A-weighting is used as it places emphasis on the middle frequencies of the noise spectrum, while putting less emphasis on the higher and lower frequencies. This emulates the way the human ear responds to sound.

A statistical analysis of the measurement was also completed so that the LAIO and LA90 over the 30 minutes could also be recorded. These recordings represent the noise levels recorded in dB (A) for 10% and 90% of the measurement time respectively. The LA10 values are used to describe intermittent, high-energy noise events and usually are a good indicator of the level of traffic. The LA90 values are representative of background noise levels and will describe the noise present for the majority (90%) of the sampling period.

In addition, Erequency analysis was carried out in the 1/3 octave band at each of the noise monitoring locations to assess the potential tonal components of ambient noise generated

in the vicinity of the facility. All sources of noise were noted, recorded and where possible, identified during the course of the survey.

Existing Noise Environment

The main noise sources from the facility consisted of the following: 0

0

0

0

Noise from the generator and lines in the MRF Noise from trucks entering the site and tipping in the MRF Noise from the shovel moving waste onsite and vehicles going over the wheel wash Customer cars entering the Civic Amenity site, leaving their recycling in the bins, the bin lids being closed and talking amongst the people at the Civic Amenity site

Other noise sources are present at the facility, which are not related to the site activities. These include:

Traffic noise from the bypass road connecting the main M3 motorway along the Eastern side of the facility and the M3/Dunboyne road to the Northwest of the facility, R157. These are very busy roads. Noise from the traffic movements within the industrial estate and the housing estate adjacent to the site. Aeroplanes, as the facility is located under a flight path to Dublin Airport.

approximately 1 km from the site. Noise within the housing estate, bird song, cars passing.

4. DISCUSSION

As mentioned previously the LA10 values are used to describe intermittent, high-energy noise events and usually are a good indicator of the level of traffic. The LA90 values are representative of background noise levels and will describe the noise present for the majority (90%) of the sampling period.

Boundary Location:

NP1- Eastern Boundary

NPl is located at the back of the site in the main yard. Noises associated with this monitoring location were mainly noises generated from activity inside the MRF such as the processing lines. Other noise sources arose from trucks loading and unloading, trucks entering and leaving the site and the shovel moving waste around the site.

No tones were recorded at this location.

NP2 - Southern Boundary

NP2 is located in the Civic Amenity site. Noise sources included the cardboard compactor, traffic entering the civic amenity site, customers using the civic amenity site, dropping materials into waste containers and bottle banks, traffic from the R157, aeroplanes and noises from operations in the MRF.

No tones were recorded at this location.

NP3 - Northern Boundary

NP3 is located midway on the Northern boundary of the site. The main noise source at location NP3 was from trucks passing over the wheel wash while entering and leaving the site, and water from a hose reel at the back of the site welfare building which remained running for the duration of the sampling time. Other noise sources included traffic on the R157. This is a very busy road which had a lot of traffic passing during monitoring. Noise from the MRF and planes overhead were other sources of noise at this location.

No tones were detected at this location.

NP4 -Western Boundary

NP4 is located beside the main office and the public entrance to the civic amenity site. The noise source recorded at NP4 was from traffic from the R157, traffic entering and leaving the civic amenity site, and trucks entering and leaving the MRF.

No tones were detected at this location.

Noise Sensitive Locations:

NP6 - Third Class Road

This monitoring point is located 250m south east of the site. The recorded noise limit was exceeded at this location (68.2dB), during the monitoring period. However the noise level at this location is largely determined by passing traffic on the road in front of the noise meter and the traffic on the bypass to the M3 motorway, R157, neither of which are associated with Thorntons Recycling facility activities. There was also contributory noise from birds and aeroplanes.

Noise meter location

rime 1 - rnocogrupn OJ moniioring iocunon ivro

A total of 55 vehicles (2 vans, 1 truck, 1 artic, and 51 cars) passed while monitoring was in progress, none of which were a Thorntons Recycling vehicle. 4 planes passed overhead during the monitoring period also. The peaks on the logging graph correspond with the passing traffic.

The LA90 is a good indicator of the noise level at the location NP6 excluding the passing traffic and this was measured to be 42.8dB, which is well below the recommended noise levels of 55dB.

Tones were detected at 3 15Hz, and 630Hz. This is thought to be linked to the continuous hum of traffic on the Dunboyne bypass.

NP5 - Luttrell Hall Housing Estate

The housing estate of Luttrell Hall is located approximately 250m south of the site. A wall 2.4m in height separates the housing estate from the industrial estate and a boundary of trees has been planted by Thorntons Recycling on the residential side. The recorded noise limit was not exceeded at this location during the monitoring period.

Noise Monitoring Report Thorntons Environmental DeDartment

The noise sources at this location were from birds, traffic on the R157, cars passing through the estate, and aeroplanes. The recorded noise level at this location was 54.ldB which is below the limit of 55dB.

A tone was detected at 630Hz. This is thought to be linked to aeroplanes passing overhead. A total of 5 planes passed overhead during the monitoring period.

5. CONCLUSION

Analysis of the results from the noise survey indicates that the noise emissions at the noise sensitive locations (NP5 and NP6) are not adversely affected by the activities of the Thorntons Recycling facility. The noise limit as set out in WO206-01 was exceeded at location NP6 however noise sources measured were mostly attributed to passing vehicles, planes overhead and local noise none of which originated from Thorntons facility. The predominant noises recorded at these locations were associated with sources unrelated to the facility.

Glossary of Terms:

Ambient noise: The totally encompassing sound in a given situation at a given time, usually composed of sound from many sources, near and far.

Background noise level: The A-weighted sound pressure level of the residual noise at the assessment position that is exceeded for 90% of a given time interval, T (LA90,T).

Criterion Noise Level: The long-term mean value of the noise level that must not be exceeded. This is generally stipulated in the IPC licence and it may be applied to a nose source, a boundary of the activity or to noise sensitive locations in the vicinity of the facility.

1/3 Octave Band Analysis: Frequency analysis of sound such that the frequency spectrum is subdivided into bands on one-third of an octave each. An octave is taken to be a frequency interval the upper limit of which is twice the lower limit (the unit of frequency is the Hertz, Hz).

Day and Night time: Day time is considered to be from 8.00 am to 10.00pm and night time is considered to be from 10.00 pm to 8.00am.

DB(decibe1) The scale in which sound pressure level is expressed. It is defined as 20 times the logarithim of the ratio between the RMS pressure of the sound field and the reference pressure of 20 micro-pascals (20 pPa).

DBA or dB(A): An “A-weighted decibel”- a measure of the overall noise level of sound across the audible frequency range (20Hz - 20kHz) with A-frequency weighting to compensate for the varying sensitivity of the human ear to sound at the different frequencies.

Facade level: Noise levels at location lm from the facade of a building are described by the term Facade Levels and are subject to higher noise levels than those in open areas (free - field locations) due to reflection effects.

Free-field Conditions: These are conditions in which the radiation from sound sources is unaffected by the presence of any reflecting boundaries. In practice it is a field in which the boundaries are negligible over the frequency range of interest. In environmental noise, true free field measurement conditions are seldom achieved and generally the microphone will be positioned at a height between 1.2 and 1.5 metres above ground level.

influence of reflections, measurements are generally made at least 3.5 meters from any reflecting surface other than the ground.

Rz (hertz): The unit of sound frequency in cycles per second.

Impulsive Noise: A noise that is of short duration (typically less than one second), the sound pressure level of which is significantly higher than the background. In determining weather a tonal adjustment applies reference must be made to IS0 1996-2 (I 987)- Section 4.1.

Impulsive Exponential- time weighting: This is a time-weighting which is available on some sound level meters and it represents an arbitrary compromise in an attempt to provide a means to measure the sound level of short-duration impulsive sounds. Impulsive time-weighting has a design goal exponential-time constant of 35 ms for sound signals that increase with increasing time and 1.5 seconds for sound signals that decrease with increasing time.

LAeqT: The equivalent steady sound level in dB containing the same acoustic energy as the actual fluctuating sound level over the given period, T.

LAmax: The maximum RMS, A-weighting sound pressure level occurring within a specified time period; the time weighting fast or slow is usually specified.

Noise: Any sound, that has the potential to cause disturbance, discomfort or psychological stress to a subject exposed to it, or any sound, that could to cause actual physiological harm to a subject exposed to it, or physical damage to any structure exposed to it, is known as noise.

Noise Sensitive Location: Any dwelling house, hotel or hostel, health building, educational establishment, place of worship or entertainment, or any other facility or other area of high amenity which for its proper enjoyment requires the absence of noise at nuisance levels.

Rating Level (L Ar,T) The specified noise level, plus any adjustment for the characteristic features of the noise.

Residual Noise: The ambient noise remaining at a given position in a given situation when the specific source is suppressed to a degree such that it does not contribute to the ambient noise (residual noise level is measured in terms of LAeq,T).

Root Mean Square (RMS):

The RMS value of a set of numbers is the square root of the average of their squares.

Sound Exposure Level (SEL or LAE): This is the measurement of the A-weighting sound energy used to describe noise events such as the passing of a train or aircraft; it is the A-weighting sound pressure level if occurring over a period of 1 second, would contain the same amount of A-weighted sound energy as the event.

Specific Noise Level: A component of the ambient noise which can be specifically identified by acoustical means and may be associated with a specific source. In BS 4142, there is a more precise definition as follows " the equivalent continuous A-weighted sound pressure level at the assessment position produced by the specific noise source over a given reference time interval (Laeq,T).

Time-weighting: One of the averaging times (Fast, Slow or Impulsive) used for the measurement of RMS sound pressure level in sound level meters.

Tonal Noise: Noise which contains a clearly audible tone, i.e a distinguishable, discrete or continuous note, (whine, hiss, screech or hum etc) In determining whether a tonal adjustment applies, reference must be made to IS0 1996-2 (1 987) - Section 4.1.

Certificate of Calibration Issued by University of Salford (Acoustics Calibration Laboratory) UKAS ACCREDITED CALIBRATION LABORATORY NO. 0801


SET-UP INFORMATION The instrument was running software module BZ7126 version 1.1 .O. The reference range, reference SPL, primary indicator range, pulse range and linearity range as specified by the manufacturer have been used. The instrument was adjusted to read 93.9 dB (A) in response to the associated calibrator. This reading was obtained from the calibration certificate of the calibrator, 02732/1 and information in the manufacturer’s instruction manual, when the instrument is configured as follows; Sound Incidence: Frontal, Windscreen Correction: Off. The instrument was calibrated without a windshield. Consult manufacturer’s instructions if using a windshield.

MEASUREMENTS The levels of self-generated noise were:

A: 13.4 dB C: 18.2 dB

Lin: 24.2 dB

At the end of the tests the indication of the sound level meter in response to the associated sound calibrator was 93.9 dB (A) which corresponds to the following level at 101.325 kPa:

Sound Pressure Level 93.9 dB (A) This reading should be used henceforth to set up the sound level meter for field use.

THE SOUND LEVEL METER WAS VERIFIED ACCORDING TO THE PROCEDURE GIVEN IN BS7580: Part 1 1997 WITH THE FOLLOWING EXCEPTIONS:

The microphone corrections applied as specified in BS 7580: Part 1: 1997 were obtained from a frequency response measurement by this Laboratory using the electrostatic actuator method. The response in isolation is not covered by our UKAS accreditation.

A stricter test than that specified in 5.5.10 and 5.5.1 1 of BS 7580 has been used by not applying the low level signal.

STATEMENT OF RESULT: THE SOUND LEVEL METER CONFORMS TO THE TYPE 1 REQUIREMENTS OF BS7580: PART1 1997.

Instruments used in the verification procedure were traceable to National Standards. The method of acoustic calibration employed a standard sound pressure calibrator for the 1 kHz test whilst the tests at 125 Hz and 8 kHz were performed by the electrostatic actuator method. The uncertainty of the LaboratoIy’s 1 kHz calibrator was *0.10 dB. The uncertainty of the standard calibrator is not included in the applied tolerances. It is assumed that the sound level meter was manufactured in accordance with BSEN6065 1 : 1994 Type 1, and BSEN60804: 1994 Type 1.

The reported expanded uncertain@ is based on a standard uncertainly multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%. The uncertainly evaluation has been carried out in accordance with UKAS requirements. All measurement results are retained at the acoustic calibration laboratory for at least four years.

This certi3cate is issued in accordance with the laboratory accreditation requirements of the United Kingdom Accreditation Service. It provides fruceabili@ of measurement to the SI system of units andor to the units of measurement realised at the National Physical Laboratory or other recognised national metrology institutes. This certificate may not be reproduced other than in full except with the prior written approval of the issuing laboratory.

MEASUREMENTS

The sound pressure level generated by the calibrator was measured using a calibrated, WS2P condenser microphone as specified in the certificate. The calibration was carried out with the calibrator in the half- inch configuration.

Five determinations of the sound pressure level, frequency and total distortion were made.

The results have been corrected to the reference pressure of 101.325 kPa using manufacturer's data.

RESULTS

Coupler configuration: Half-inch Microphone type: GRAS 40AG

Output level (dB re 20pPa): 94.06 dB f 0.10 dB Frequency (Hz): 999.96 Hz f 0.12 Hz

Total Harmonic Distortion (%): 0.46 % f 0.15 % (Not UKAS Accredited)

Average environmental conditions at the time of measurement and maximum deviation from the stated average:

Pressure: 101.550 kPa f 0.016 kPa Temperature: 22.6 "C f 0.4 "C

Relative humidity: 38.5 % f 1.7 %

The reported expanded uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a coverage probability of approximately 95%. The uncertainty evaluation has been carried out in accordance with UKAS requirements.

All measurement results are retained at the acoustic calibration laboratory for at least four years.

This certificate is issued in accordance with the laboratory accreditation requirements of the United Kingdom Accreditation Service. I t provides traceability of measurement to the SI system of units and/or to the units of measurement realised at the National Physical Laboratory or other recognised national metrology institutes.
