4 1.0 INTRODUCTION: 1.1 Noise & Vibration Consultants Ltd ( NVC ) have been instructed by Fichtner Consulting Engineers Ltd to review the proposed site layout and data for the proposed EfW site and the cumulative effect of the operation of the IBA Facility to establish the likely noise impact at nearby receptors. 1.2 Where the review indicates that there is a potential exceedance of the proposed noise criteria according to BS4142: 1997, NVC would advise on additional measures that may be required to ensure compliance. 1.3 The areas of new plant relevant to the planning application relates to the following equipment (as shown on Figures 1, 2 & 3 attached): Energy From Waste (EfW) Plant: Plant Enclosed Within Building (i) (ii) (iii) (iv) (v) (vi) (vii) (viii) (ix) (x) Tipping Hall & Refuse Bunker Furnace & Boiler Hall Flue Gas Treatment Hall Compressor Room Bottom Ash Electrical Room Workshop Demineralised Water Hall Turbine Hall Weighbridge Plant External to EfW Building (xi) (xii) (xiii) Air cooled condenser Turbine Air Coolers Ventilation Stack IBA Plant (i) Reception area (ii) Maturation & Storage area (iii) Mobile plant (iv) HGVs (v) Process Building containing: Conveyors Trommel Screen Screen Box Overband Magnet Mobile plant 1.4 The EfW facility applicable to this assessment would operate 24 hours a day and 7 days a week. Vehicular movements (both HGVs and staff vehicles) associated with the facility would normally only occur during the daytime between 07:00 and 18:00. Furthermore, waste deliveries by HGV would only occur during weekdays (Monday to Friday). Report No. R /1/DRK Page 1

5 1.5 The IBA facility would operate 7 days per week with IBA from the Lincolnshire EfW being continuously delivered to the site via a conveyor. The hours proposed for delivery of additional IBA from off site locations to the facility by road would relate to daytime periods from 0700 to 1800 hours. 1.6 Information used in this review has been obtained from the following sources: plan of the site relative to the nearest receptors; information relating to the layout of the proposed site; British Standards BS4142: 1997 & BS8233: 1999; CNIM report / Iss A `Lincoln Energy from Waste Plant - Acoustic Study dated 6 September 2011; chapter 10 of the Environmental Statement: Part One for the Energy from Waste Facility for Lincolnshire; figure 10.1 of the Environmental Statement: Part One for the Energy from Waste Facility for Lincolnshire; IBA noise impact assessment chapter from the ES as provided by NVC Ltd ISO `Attenuation of sound during propagation outdoors Part 2: General Method of Calculation : 1996 Report No. R /1/DRK Page 2

6 2.0 RECEPTORS, BASELINE LEVELS & NOISE CRITERIA 2.1 Chapter 10 of the ES provided by Lincolnshire County Council sets out the noise criteria, receptor locations and baseline noise monitoring for the proposed EfW facility, extracts of which are detailed below: Monitoring Locations Given the nature of the proposed development and the surround land uses, a number of sensitive noise receptors have been selected which have formed the basis of the assessment. These are set out in Table 10.3 and take account of the likely operating regime of the facility and the degree of sensitivity of the receptor. Table 10.3 Noise Sensitive Receptors Location Sensitivity Approx distance to site boundary St Nicholas Day Nursery Moderate 350m to the west Whisby Road (southern façade) 29 Cottesmore Road High 600m to the north (southern façade) 14 Grace Avenue High 750m to the south (northern façade) Plant Hire Office on Paving Way Moderate 25m to the north (southern façade) Wirtgen Ltd Office on Paving Way Moderate 50m to the north (eastern façade) Ibis Hotel (southern Moderate 400m to the west 20m height Sensitivity Following a site visit, the closest noise sensitive locations were selected for the baseline noise survey. The following locations were therefore used as monitoring locations and are identified on Figure 10.1: St Nicholas Day Nursery on Whisby Road. Adjacent to 29 Cottesmore Road. Field adjacent to 14 Grace Avenue. Front car park of Wirtgen Ltd, Paving Way The residential properties and day nursery are considered to be more noise sensitive than the Wirtgen Ltd commercial facility. The day nursery will be noise sensitive during the daytime, but not in the evening or night time. Conversely the Ibis hotel, near to the day nursery, will be more noise sensitive during the evening and night time than the daytime. The commercial property considered will have some noise sensitivity but only during their operating hours. The residential properties will be more noise sensitive during the evening and night time but for the purpose of the assessment are considered noise sensitive for all periods.

The full results are detailed in Appendix Table 10.4 Summary of Noise Measurements Location Time Period Average Measured Noise Levels db Lowest noise level db LAeq LA 1 LA 10 LA 90 LA 90 St Nicholas Day Daytime **54 Nursery Night time Cottesmore Road Daytime Night time Grace Avenue Daytime Night time Plant Hire Office Daytime *44 on Paving Way) Wirtgen Ltd Office Daytime on Paving Way Ibis Hotel Night-time (southern 20m height *Background noise level taken from closest receptor considered in baseline assessment for daytime and night-time. ** Minimum background noise level recorded between 07:30 and 20:00 (nursery opening hours) Road traffic was considered the dominant noise source at all of the monitoring locations. At the Grace Avenue monitoring location, noise from children playing and vehicle repairs was also noted. At 29 Cottesmore Road noise from birds and people in conversation on the main road was noted. At the day nursery noise from an extract fan was noted, whilst at the Wirtgen monitoring location noise from mobile plant on the adjacent Len Kirk Plant Hire site (the proposed development site) was noted. Discussion in Respect of Noise Criteria 2.2 Chapter 10 of the Environmental Statement makes reference to appropriate noise criteria. BS4142: 1997 is referred to which is the ` Method for Rating Industrial Noise Affecting Mixed Residential and Industrial Areas. This standard gives a method for establishing the likelihood of complaints relating to noise from industrial establishments made by persons living in residential properties. 2.3 The British Standard states: A difference of around +10dB or more indicates that complaints are likely. A difference of around +5dB is of marginal significance. If the rating level is more than 10dB below the measured background noise level this is a positive indication that complaints are unlikely. 2.4 The relevant standard for the assessment of noise for residential properties is BS4142: The monitoring locations in Chapter 10 include positions at offices and commercial properties. The relevant standard for offices relates to BS8233: 1999, which is summarised below in Table 2.1. Report No. R /1/DRK Page 4

8 Table 2.1: BS8233: 1999 Internal noise level guidance for Offices and Hotel Bedrooms Criterion Typical Situation Design Range, LAeq, db Good Reasonable Reasonable conditions for study Cellular office and work requiring concentration Meeting Room/ Executive Office Reasonable conditions for Bedrooms sleeping and Resting Reasonable listening conditions Classroom The above design range relates to noise levels within sensitive rooms. The attenuation from an open window, referred to in BS8233: 1999 (and other guidance) is -10 to -15dB(A). Therefore to achieve a `good design according to the standard, the level outside an office would be within the range 40-50dB(A) Leq and for a `reasonable standard a level of between 50-55dB(A) Leq, For the hotel bedrooms, a `good design range would also be between 40-50dB(A) Leq and for the nursery a range between 45-55dB(A) Leq would be appropriate. 2.6 The noise limits according to BS4142: 1997 for residential property locations (including the Ibis Hotel) is as shown below in Table 2.2.

9 3.0 NOISE PREDICTIONS Information 3.1 A report from the technology supplier of 26 July 2010 provides detailed analysis of all the key elements of the EfW facility. The areas of plant listed in the report include the following: a) Air cooled condensers ( ACC ) b) Tipping hall and refuse bunker c) Turbine Air Coolers d) Flue Gas Treatment Hall e) Stack f) Compressor Room g) Furnace & Boiler Hall h) Bottom Ash i) Electrical Room j) Workshop night k) Demineralised water hall l) Turbine Hall 3.2 Of the above, the most significant noise sources would relate to the air cooled condensers, air coolers and ventilation stack as these are located outside the building envelope. 3.3 Section 1.0 of The report details the Sound Power Levels or reverberant Sound Pressure Levels from each plant area in terms of octave band frequency spectra and LAeq level. This section also details the type of building material and ventilation silencers used for the noise prediction model. Further information has been obtained from the technology supplier in respect of the assumed wall areas for each of the facility plant areas. 3.4 Sections 2 to 4 provide plans and plant noise models used in the prediction calculations. The site plan of the plant and surrounding area show the noise monitoring positions together with the assumed distance between the receptor and the plant centre. 3.5 Section 5.0 of the report details the acoustic performance of the assumed building materials and acoustic louvres and doors. 3.6 Section 6.0 provides the calculation detail in respect of the noise contribution from each noise source within the model at each receptor location, giving the noise level and cumulative noise levels with all plant operating. 3.7 Noise prediction modelling of the site based on the information provided by the technology supplier using CadnaA noise prediction software. The results of the noise mapping are shown below in Table 3.1 and Appendix 3. The model utilises ISO9613 as the method of calculation for propagation from the building to the receptor. The ground factor G) used in the calculations = 0.5, the temperature assumed is 10degC and 70 RH. Report No. R /1/DRK Page 6

10 3.8 Design information provided by the technology supplier would indicate that the Air Cooled Condensers ( ACC ) would be fitted with a screen, above the fans (in the form of a 4 sided 8 metre high windscreen). The short sides of the ACC would also be screened off at low level (below the radiator area), which has been included in the noise predictions. 3.9 The results of the noise predictions are provided below in Table 3.1. This table does not include for the operation of the IBA facility, which is dealt with in Table 3.2. Table 3.1: EfW Site Only: Noise Prediction Results Location Period NVC Predicted Operational Noise Level db LAeq St Nicholas Day Nursery on Whisby Rd 29 Cottesmore Road (southern façade) 14 Grace Avenue (northern façade) Plant Hire Office on Paving Way) Wirtgen Ltd Office on Paving Way Limit According to BS4142: 1997 before `complaint likely & BS8233: 1999 d(daytime) (BS8233: 1999 goodreasonable design limit) (Daytime) (Night time) (Daytime) (Night time) * 27.3* <49 <43 <42 <36 (Daytime) (BS8233: 1999 goodreasonable design limit) (Daytime) (BS8233: 1999 goodreasonable design limit) Ibis Hotel (southern façade) (Night time) 38.1 <47 20m height (BS8233: 1999 goodreasonable design limit) *Note: At Grace Avenue model allows for large building north of this position 3.10 The above results relative to the EfW facility only, show the following: (a) Noise levels at the residential receptor locations would indicate `complaints unlikely in accordance with BS4142: (b) For the non-residential receptors, BS8233: 1999 is the relevant guidance and therefore BS4142: 1997 would not be appropriate. In this instance the predicted noise from fixed plant within the Plant Hire office would be well within a `good design range with windows open. At the Wirtgen office a `good design range is likely to be achieved with windows closed and with windows open just within a `reasonable design range is likely. For the nursery a `good design level would be also achieved with windows open The calculations undertaken do not take into account any influence from HGV movements to and from the development, which would not normally be included in the assessment of the EfW plant as the guidance and standards are not designed to assess this type of noise source. The calculations also assume that under normal operations, doors into the facility would be in the closed position. Report No. R /1/DRK Page 7

11 Cumulative Effect of EfW and IBA Facilities in Operation 3.12 The cumulative effect of the EfW and IBA facilities operating together has been assessed For the night-time scenario, the IBA facility would have the conveyor operating between the EfW and the IBA and possible internal work within the processing building. There would no activity between the external reception, storage and maturation areas and the processing building.

12 4.0 CONCLUSIONS 4.1 This assessment concludes the following: (i) (ii) (iii) (iv) (v) (vi) The detailed construction, layout and noise levels of all relevant plant have been provided by the technology supplier and have been used in the noise prediction model. All fixed plant noise sources have been taken into account and the mobile plant in operation at the IBA facility. Appropriate settings for the noise model have been implemented to give a robust indication of the likely noise contribution from the site with all fixed plant in operation. The results of the noise predictions at receptor locations show compliance with BS4142: 1997 at residential and hotel receptors. The results of the noise predictions at the office locations would show that a `reasonable to good design range would be achieved. With windows open, the level within offices at the Wirtgen Offices is likely to fall just within the `reasonable design range. At the Len Kirk Plant Hire offices, with windows open, the level within offices is likely to fall well within the `good design range. At the St Nicholas Day Nursery, the assessment predicts noise levels that would comply with a `good design range with windows open. (vii) The noise model assumes that the Air Cooled Condenser screen would be implemented. (viii) The noise model assumes that all ventilation openings will be fitted with 300mm acoustic louvres or acoustic baffles. Extractors fitted with in-duct silencers downstream of the fan. 4.2 The analysis of the site noise contribution indicates that the most significant noise contributor would relate to the following areas of plant: (i) (ii) (iii) (iv) (v) Air cooled condenser (without screening) Turbine Air coolers Chimney Stack Turbine Hall Walls and ventilation Boiler Room Walls 4.3 For the IBA facility, the proposed mitigation measures include the following: (a) (b) During detailed design, particular attention would be paid to the specification of plant and equipment to minimise the potential for noise emissions to have tonal or impulsive characteristics (e.g. mobile plant working on site fitted with broadband noise type reverse alarms). IBA Process Building to be constructed from building cladding having a minimum Rw of 23dB. Report No. R /1/DRK Page 9

19 APPENDIX 1 BASIC ACOUSTIC TERMINOLOGY Sound is produced by mechanical vibration of a surface, which sets up rapid pressure fluctuations in the surrounding air. Sound Pressure Level is a measurement of the size of these pressure fluctuations. It is expressed in decibels (db) on a logarithmic scale. Each 3 db increase in sound pressure level represents a doubling of the sound energy. An increase of around 10dB is said to subjectively double the sound level. The threshold of hearing is approximately 0 db. The rate at which the pressure fluctuations occur determines the pitch or frequency of the sound. The frequency is expressed in Hertz (Hz), that is, cycles per second. The human ear is sensitive to sounds from about 20 Hz to 20,000 Hz. Although sound can be of one discrete frequency - a 'pure tone' - most noises are made up of many different frequencies. The human ear is more sensitive to some frequencies than others, and modern instruments can measure sound in the same 'subjective' way. This is the basis of the A-weighted sound level db(a), normally used to assess the effect of noise on people. The db(a) weighting emphasises or reduces the importance of certain frequencies within the audible range. Noise Measurement The measurement of sound pressure level is only really meaningful where the level of noise is constant. In the typical industrial environment noise levels can vary widely and sometimes short duration high levels of noise are interspersed with periods of relative quiet. The most widely used means of 'averaging' the noise over a period of time is the Equivalent Continuous Sound Level. Normally written as L Aeq this value takes into account both the level of noise and the length of time over which it occurs. There are many meters available which are capable of measuring L Aeq by electronic integration over the measurement period. The L Aeq or A-weighted equivalent continuous noise level is a measure of the total noise energy over a stated time period and includes all the varying noise levels and re-expresses as an 'average', allowing for the length of time for which each noise level was presented. The L An parameters are defined as the noise levels which are exceeded for n% of the monitoring period, thus, for example, the L A90 parameter is the noise level exceeded for 90% of the 15 minute period, i.e minutes. The L A50 parameter is the noise level exceeded for 50% of the hourly period, i.e. 30 minutes, etc. The L max parameter is the maximum RMS A-weighted noise level occurring during the measurement period. The definition in layman s terms is given below for terminology used in the measurement and results obtained during the survey work. Report No. R /1/DRK

20 A-weighting: Normal hearing covers the frequency (pitch) range from about 20Hz to 20,000 Hz but sensitivity of the ear is greatest between about 500Hz and 5000Hz. The "A-weighting" is an electrical circuit built into noise meters to mimic this characteristic of the human ear. Ambient noise: The totally encompassing sound in a given situation at a given time usually composed of sound from many sources near and far. Attenuation: Noise reduction Background noise: The general quiet periods of ambient noise when the noise source under investigation is not there. Decibel (db): The unit of measurement for sound based on a logarithmic scale. 0dB is the threshold of normal hearing; 140dB is the threshold of pain. A change of 1dB is only detectable under controlled laboratory conditions. db(a) [decibel A weighted]: Decibels measured on a sound level meter incorporating a frequency weighting (A weighting) serves to distinguish sounds of different frequency (or pitch) in a similar way to how the human ear responds. Measurements in db(a) broadly agrees with an individual's assessment of loudness. A change of 3dB(A) is the minimum perceptible under normal everyday conditions, and a change of 10dB(A) corresponds roughly to doubling or halving the loudness of sound. db(c): [decibel C weighted]: Frequency weighting which does not alter low frequency octave band levels by very much compared to `A' weighting. Similar to linear reading (i.e. linear does not alter frequency spectra at all) Frequency (Hz): The number of sound waves to pass a point in one second. L Aeq : This is a noise index used to describe the "average" level of a noise that varies with time (T). It allows for the different sensitivities of the human ear to different frequencies (pitch), and averages fluctuating noise levels in a manner, which correlates well with human perceptions of loudness. L A10,T : This noise index gives an indication of the upper limit or peak levels of the fluctuating noise. It is the "A weighted" noise level exceeded for 10 per cent of the specified measurement period (T). e.g. If the measurement period was over 10 hours and the L A10 reading was say 60dB, then this means that for 1 hour out of 10 the level went above 60dB. L A90,T : This noise index gives an indication of the lower limit or levels of the fluctuating noise. It is the "A weighted" noise level exceeded for 90 per cent of the specified measurement period (T). e.g. If the measurement period was over 10 hours and the L A90 reading was say 50dB, then this means that for 9 hours out of 10 the level went above 50dB. Report No. R /1/DRK

21 L Amax : This is the highest `A weighted noise level recorded during a noise measurement period. Residual noise: The ambient noise remaining at a given position in a given situation when the noise source under investigation is not there. Specific noise: The noise source under investigation for assessing the likelihood of complaints Examples of typical noise levels Source/Activity Indicative noise level [db(a)] Threshold of hearing 0 Rural night-time background Quiet bedroom 35 Wind farm at 350m Busy road at 5km Car at 65km/h at 100m 55 Busy general office 60 Conversation 60 Truck at 50km/h at 100m 65 City Traffic at 5m Pneumatic drill at 7m 95 Jet aircraft at 250m 105 Threshold of pain 140 Report No. R /1/DRK
