3 1.0 Executive Summary Limited is required as part of licence W ; Conditions 4 and 6 to carry out a noise survey of the installation on an annual basis. AXIS environmental services were commissioned to complete the survey after proposal acknowledgment and acceptance by s Environmental Department. The purpose of the survey was to monitor noise at three boundary locations on the site as well as one noise sensitive location and assess the sites compliance against Schedule B limits. The survey was carried out in strict accordance with the standard ISO 1996 Parts 1 3, Acoustics description, measurement and assessment of environmental noise. Reference was also made to the EPA guidelines NG4 Guidance Note for Noise: Licence Applications, Surveys and Assessments in Relation to Scheduled Activities January All operations at were running as normal throughout the survey. The majority of the noise sources at the boundary points were from site activities. There was also significant noise from traffic movements on the M7 motorway and a nearby local access route that connects the R409 to Osberstown. A lorry which was parked with the engine running was a significant cause of noise at NM1 during the evening survey. There were other sources of noise at each individual location which are summarised in the report. The impact of road traffic noise could be a significant interference on the survey at certain locations as defined in the report. As outlined in the Standard ISO 1996 and the associated noise guidance document issued by the Agency, where traffic noise is interfering with noise measurements, it is acceptable to assess noise compliance against the LA90 for the monitoring period. This is a statistical measurement of the noise level exceeded for 90% of the time which would largely be associated with the facility under assessment. Four monitoring points were monitored for the noise survey. NM1, NM2 & NM3 are boundary monitoring points which are located within the confines of the site and are in close proximity to activities in operation. These monitoring locations would not be considered noise sensitive locations. NSL1 is a noise sensitive location which is located in close proximity to a local residence. This monitoring point is required to be compliant with noise emission limit values [Day 55dB(A), Evening - 50dB(A) & Night 45dB(A)] All monitoring points were determined to comply in full with licence requirements. There was no tonal or impulsive noise observed at either location for the duration of the assessment. Page 3 Report Number: Version 1

4 2.0 Introduction As part of compliance monitoring at, an annual noise survey is to be carried out at noise sensitive receptors in the vicinity of the plant. The Agency and have agreed on the monitoring points on the boundary of the site and at the nearest noise sensitive locations.

6 4.0 Monitoring Locations 4.1 Noise Monitoring Point 1 (NM1) Day Time Survey Noise monitoring point NM1 is located at the entrance of the site on the Southern boundary, close to the Main Process Building. The greatest source of noise at this location is the noise created by front loaders moving glass from and to prefab storage areas. The front loaders were also loading glass into trucks arriving on site. Noise from the front loaders reversing was also clearly audible at this point. Other sources of noise noted at this location were from site traffic entering and leaving site and from the bucket elevators coming from the main processing plant. Noise from the process building conveyors which move the glass was also consistent for the duration of the monitoring period NM1 Evening Time Survey During evening time monitoring the main most prevalent sound noted was the continuous operation of the main processing plant nearby. The other dominant noise was that from the wheeled loaders moving around the site. A lorry was also heard nearby briefly NM1 Night Time Survey For the night time survey, the greatest source of noise was from a lorry which was parked nearby with the engine running. This resulted in the final result 48dB(A) exceeding the limit for night time noise 45dB(A). This was not as a result of process activities in operation at. Other sources noise noted at this location included operational noise from the facility. 4.2 Noise Monitoring Point 2 (NM2) Day Time Survey This noise monitoring Point was located on the North Western boundary of the site, close to Storage Bays and the Drying Shed. The main source of noise at this location was the operational noise from the dryers and hoppers in the drying plant. Traffic noise from the M7 and the regional road R409 were clearly audible at this monitoring point. Other sources of noise at this monitoring point were from the front loaders moving sand from storage bays 10m from noise meter.

12 6.0 Conclusions Four locations were monitored for broadband and 1/3 rd Octave frequency as part of this annual environmental noise survey at Limited. Boundary points were monitored for 30 minute periods during the day, evening and night time survey while the noise sensitive location was monitored for 3*30 minute periods during the day, 1 *30- minute period during the evening and 2*30 minute periods at night NSL1, a noise sensitive location, was determined to be in full compliance with the requirements of the site s EPA issued waste license. The LA90 was used for the evening and night time results in order to remove the noise from external traffic sources which and other intermittent noises from the surrounding area not associated with. The findings of the survey would indicate that the noise sensitive locations were not significantly affected or impacted by sources of noise at Glassco Recycling Limited. Boundary noise location NM1 had elevated LAeq noise levels during the night due to a lorry which was parked nearby with the engine running. Other factors contributing to noise levels were the location s proximity to the main site activities and the increased sound intensity emanating from traffic on M7 motorway and a local access route. However, this would be considered a boundary monitoring point and not a noise sensitive receptor. There was no tonal noise determined at any monitoring location; therefore there are no requirements to apply penalties to the broadband measurement. Page 12 Report Number: Version 1

13 Appendix I Graphical Display of Raw Data Tonal Noise: The appropriate level differences vary with frequency. They should be greater than or equal to the following values in both adjacent one third octave bands: 15dB in low frequency one third octave bands (25Hz to 125Hz); 8dB in middle frequency bands (160Hz to 400Hz), and; 5dB in high frequency bands (500Hz to 10,000Hz) This is the definition outlined by the EPA in the guidance note issued in 2012: NG4.

40 Appendix IV: Glossary of Terms Note: Not all terms were used in the description of noise for this noise survey. Ambient noise Acoustic shadow Background noise Broadband Competent person The totally encompassing sound in a given situation at a given time, usually composed of sound from many sources, near and far. An acoustic shadow is an area through which sound waves fail to propagate, due to topographical obstructions or disruption of the waves via phenomena such as wind currents. 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). Sounds that contain energy distributed across a wide range of frequencies. Individual possessing a combination of technical knowledge, experience and skills as outlined in Section 2.0 and who can demonstrate both practical and theoretical competence. Criterion noise level The long term mean value of the noise level that must not be exceeded. This is generally stipulated in the IPPC/Waste licence and it may be applied to a noise source, a boundary of the activity or to an NSL in the vicinity of the site. db Decibel. The scale in which sound pressure level is expressed. It is defined as 20 times the logarithm of the ratio between the RMS pressure of the sound field and the reference pressure of 20 micro pascals (20 upa). Facade level Free field The noise level at a location 1m from the facade of a building is described by the term facade level, and is subject to a higher noise level than one in an open area (free-field conditions) due to reflection effects. These are conditions in which the radiation from sound sources is unaffected by the presence of any reflecting boundaries or the source itself. In practice, it is a field in which the effects of 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. To minimise the influence of reflections, measurements are generally made at least 3.5 metres from any reflecting surface other than the ground. Hertz (Hz) Impulsive LAeq,T LAFN LAr,T The unit of sound frequency in cycles per second. A noise that is of short duration (typically less than one second), the sound pressure level of which is significantly higher than the background. This is the equivalent continuous sound level. It is a type of average and is used to describe a fluctuating noise in terms of a single noise level over the sample period (T).The closer the LAeq value is to either the LAF10 or LAF90 value indicates the relative impact of the intermittent sources and their contribution. The relative spread between the values determines the impact of intermittent sources, such as traffic, on the background. The A-weighted noise level exceeded for N% of the sampling internal. Measured using the Fast time weighting. The Rated Noise Level, equal to the LAeq during a specified time interval (T), plus specified adjustments for tonal character and/or impulsiveness of the sound. Page 40 Report Number: Version 1 EPA Export :17:28:13

41 LAF10 LAF90 LAFmax LAFmin Lden Refers to those A-weighted noise levels in the top 10 percentile of the sampling interval; it is the level which is exceeded for 10% of the measurement period. It is used to determine the intermittent high noise level features of locally generated noise and usually gives an indicator of the level of road traffic. Measured using the Fast time weighting. Refers to those A-weighted noise levels in the lower 90 percentile of the sampling interval; it is the level which is exceeded for 90% of the measurement period. It will therefore exclude the intermittent features of traffic and is used to describe a background level. Measured using the Fast time weighting. The maximum RMS A-weighted sound pressure level occurring within a specified time period. Measured using the Fast time weighting. The minimum RMS A-weighted sound pressure level occurring within a specified time period. Measured using the Fast time weighting. Is the 24 hour noise rating level determined by the averaging of the Lday with the Levening plus a 5 db penalty and the Lnight plus a 10 db penalty. Low background noise An area of low background noise is one where the existing background noise levels measured during an environmental noise survey are as follows: Low frequency noise LpA (db) Noise Average Daytime Background Noise Level 40dB LAF90, and; Average Evening Background Noise Level 35dB LAF90, and; Average Night-time Background Noise Level 30dB LAF90. LFN - noise which is dominated by frequency components towards the lower end of the frequency spectrum; see Appendix VI for a more detailed discussion. An A-weighted decibel K a measure of the overall level of soundacross the audible frequency range (20Hz 20kHz) with A-frequency weighting (i.e. A weighting ) to compensate for the varying sensitivity of the human ear to sound at different frequencies. Any sound, that has the potential to cause disturbance, discomfort or psychological stress to a person exposed to it, or any sound that could cause actual physiological harm to a person exposed to it, or physical damage to any structure exposed to it, is known as noise. Noise sensitive location NSL 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. Octave band Rating level RMS SEL (LAX or LAE) Sound pressure level A frequency interval, the upper limit of which is twice that of the lower limit. For example, the 1,000Hz octave band contains acoustical energy between 707Hz and 1,414Hz. The centre frequencies used for the designation of octave bands are defined in ISO and ANSI standards. See LAr,T. The RMS (Root Mean Square) value of a set of numbers is the square root of the average of their squares. Sound exposure level a measure of the A-weighted sound energy used to describe noise events such as the passing of a train or aircraft; it is the A-weighted sound pressure level if occurring over a period of 1 second, would contain the same amount of A-weighted sound energy as the event. Sound pressure refers to the fluctuations in air pressure caused by the passage of a sound wave. It may be expressed in terms of sound pressure level at a point.

42 Specific noise level Time weighting Tonal 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). One of the averaging times (Fast, Slow or Impulse) used for the measurement of RMS sound pressure level in sound level meters. Sounds which cover a range of only a few Hz which contains a clearly audible tone, i.e. distinguishable, discrete or continuous noise (whine, hiss, screech, or hum etc.) are referred to as being tonal. 1/3 octave analysis Frequency analysis of sound such that the frequency spectrum is subdivided into bands of one third of an octave each.
