Noise Impact Assessment Relocation Of Recycling Business Pytchley Road, Kettering 15th October 2014

Report No. R14.0909/DRK WEEE Environmental (GB) Ltd

Summary

1. This noise impact assessment has been prepared in support of the relocation of a Waste Recycling Business at Pytchley Road, Kettering.

2. Background noise measurements have been undertaken at the

nearest residential boundaries during a typical weekday and weekend period to cover the lowest likely background levels.

3 Measurements were undertaken at the existing site at Mill Road Works in Wellinborough for information on typical site operational noise levels during peak noise events.

4. Advice on noise limit criteria from the Local Authority from similar sites

in the Kettering area have been based on the application of BS4142: 1997 from fixed plant noise levels during operations and for any night-time vehicular movement noise limits should have consideration of BS8233: 2014 absolute guidance limits for sleep disturbance at the nearest sensitive residential properties.

Existing Noise Climate:

5. The results of the investigations into the existing noise climate have established the following:

(i) The results show that daytime average background noise

levels (i.e. LA90) at the nearest receptors are 48dB during the weekday and 42dB LA90 at the weekend. Average LAeq levels during daytime periods vary between 55dB and 58dB.

(ii) The range of LAeq readings during the night-time monitoring periods on Saturday and Sunday (based on 1 hour readings) is shown to be between 39dB and 52dB and average LA90 levels of 32-33dB.

Conclusions

6. The results of the measurements and detailed analysis have shown the following:

(i) The application of appropriate guidance and standards has

enabled reasonable noise criteria to be adopted for daytime and night- time operations. This would be in accordance with BS4142: 1997 and sleep disturbance criteria in accordance with WHO guidelines.

(ii) The operating hours for the development would be between 0700 to 1800 hours Monday to Friday and 0700 to 1400 on Saturdays. Occasional n ight-time offloading of refrigeration plant would take place at the eastern end of the site with appropriate noise mitigation measures to ensure residential amenity is protected.



(iii) At the nearest residential property boundary positions, the

highest likely predicted noise levels during daytime operations (without further noise mitigation measures) are calculated to be between 43dB(A) to 48dB(A) Leq1hr during daytime activities. With the proposed mitigation measures in place, the resultant noise levels fall to a range of 37dB(A) to 46dB(A) Leq1hr. The attenuated levels are below existing background noise levels (i.e. an LA90 level).

(iv) During the occasional night-time offloading of HGVs at the

eastern end of the site the predicted noise levels (without further noise mitigation measures) are calculated to be between 34dB(A) to 42dB(A) Leq5mins during night-time activities. With the proposed mitigation measures in place, the resultant noise levels fall to a range of 32dB(A) to 37dB(A) Leq5mins (43dB to 48dB LAmax). The attenuated levels are therefore below existing background noise levels and below sleep disturbance criteria according to WHO guidance and BS8233: 1999 design limits within bedrooms.

(v) With the proposed development in operation, without any noise mitigation measures, a BS4142 assessment indicates that the highest weekday daytime noise levels are unlikely to lead to complaint, however during Saturdays without further mitigation noise levels could result in complaint. The implementation of proposed noise control measures show that complaint would then be unlikely at the nearest residential receptors.

(vi) Occasional seasonal offloading of HGVs during night-time

periods at the eastern end of the site with the proposed mitigation measures would be within all relevant guidance to protect residential amenity and sleep disturbance criteria.

7. Taking into account the hours of operation, the site layout, the noise

control measures proposed, subjective observations of existing ambient noise levels, measured operational noise levels and the relative position of the nearest residential properties to the noise source, it is our expert opinion that resultant noise level would comply with appropriate and relevant guidance and standards and would provide adequate protection for residential amenity.

1.0 INTRODUCTION:

1.1 Noise & Vibration Consultants Ltd (“NVC”) have been instructed by WEEE Environmental (GB) Ltd to prepare a noise impact assessment in respect of the relocation of a Waste Recycling of Electrical Equipment at Pytchley Road in Kettering.

1.2 This assessment is being prepared in support of a planning application to establish any impact arising from operational activities on local residents from noise and to ensure that they are not significantly affected by the introduction of the development.

1.3 Where appropriate, NVC would provide recommendations for noise

amelioration measures to reduce the effect of noise on any existing dwellings to an acceptable level.

Assessment Aims and Objectives

1.4 The aim of this assessment is to provide information for the planning application in relation to the impact of noise from the development on existing residential receptors. This includes the provision of the following:

Provides information on typical existing site noise climate.

Provides information on typical noise levels from fixed and mobile plant likely to be used at the facility.

Provides information on the highest likely predicted noise from fixed and mobile plant on site and from the operation of the depositing/loading activities at the nearest residential properties.

Where appropriate, provides recommendations for any relevant noise mitigation measures necessary to meet appropriate noise guidance and standards.

1.5 The potential noise impacts, identified above, are considered in the context of

the existing background noise at the site, which is predominantly influenced by industrial noise, intermittent train noise and distant road traffic noise.

Survey Work

1.6 As part of this assessment a site inspection and baseline noise survey was

carried out from Friday 26 th to Monday 29th September 2014. This survey was undertaken over a 3 day weekend period to determine the lowest likely background noise levels adjacent to existing residential properties. The study also benefits from a noise survey at the existing site.

1.7 The proposed facility includes processing buildings and plant relevant to the

operations at the site. These elements are illustrated on Figure 2 and listed below.

(i) Refrigeration/WEEE storage areas (ii) Electrical waste recycling building (iii) Offices (iv) Service Yard (v) Mobile plant



(vi) Staff and car parking area

1.8 The facility is proposed to operate during the following hours:

Monday to Friday: 0700-1800 hours Saturday: 0700-1400 hours

1.9 Information used in this review has been obtained from the following sources:

aerial plan of the site relative to the nearest receptors;

information relating to the layout of the proposed site;

2.1 SITE DESCRIPTION

2.2 Introduction

2.2.1 The application site is located approximately 2km south of Kettering town centre on Kettering Business Park. The site is adjacent to a number of industrial businesses including a waste metal recycling facility.

2.2.2 The site benefits from an existing junction off Pytchley Lodge Road, which connects to a junction with Pytchley Road circa 100m east of the main building on site.

2.2.3 The application site is located on land currently vacant, which incorporates an

existing office, three industrial buildings and a large service yard area.

2.2.4 The northern boundary of the site is adjacent to an elevated section of a main line railway between Kettering and Wellingborough.

2.2.5 The main source of existing noise affecting nearest property positions relates

to industrial noise and the movement of road and rail traffic.

2.3 Baseline Noise Monitoring Position

2.3.1 Baseline noise monitoring was undertaken in the vicinity of the rear boundaries of the nearest residential properties north of the railway line.

2.3.2 Figure 1 attached shows the site position relative to the baseline noise monitoring positions.

2.4 Nearest Sensitive Receptors

2.4.1 The nearest residential receptors are located to the north on the opposite side of the railway line off Langley Way at a distance of approximately 30m from the end wall of the main building.

2.4.2 Figure 1 attached, shows the site position relative to the nearest existing residential properties.

2.5 Site Activities

2.5.1 The facility would manage waste metal reclamation from electrical goods and commercial refrigeration plant.

2.5.2 Recyclable metal waste would be transported to the site before being offloaded and stripped. The metal would be stored in appropriate transport containers before being loaded into HGVs for onward transportation.

2.5.3 Forklift trucks would be used on site to offload and load refrigeration plant

and to assist the movement of material around the site.



3.1 SITE SURVEY NOISE RESULTS

3.2 Background Noise Results:

3.2.1 Results recorded at nearest properties south of the site are detailed below.

Position 1 – Rear of properties off Langley Way

3.2.2 Measurements were recorded over typical weekend period under suitable

monitoring weather conditions. The measurements were carried out using a type 1 noise meter with wind protection. The microphone was mounted on a tripod to a height of 1.5 metres above ground level. The noise level analyser was calibrated prior to commencement of the survey and following its completion. There was no change in the calibration level noted. The instruments are within calibration and calibration certificates can be provided to traceable national standards.

3.2.3 The average and range of results for the monitoring period are as follows:

3.2.4 The above results show that daytime average background noise levels (i.e. LA90) at the nearest receptors are 48dB during the weekday and 42dB LA90 at the weekend. Average LAeq levels during daytime periods vary between 55dB and 58dB.

3.2.5 The range of LAeq readings during the night-time monitoring periods on Saturday and Sunday (based on 1 hour readings) is shown to be between 39dB and 52dB and average LA90 levels of 32-33dB.

3.3 Existing Site Noise Survey Results:

3.3.1 We have undertaken detailed noise measurements around the existing WEEE Environmental site at close range to plant equipment and at building door openings during peak impact noise to measure the highest likely site noise levels.

3.3.2 The following tables detail noise levels measured in terms of overall noise levels and frequency characteristics, which enables us to utilize in noise prediction calculations.

3.3.5 Graph 3.1 below shows tonal noise characteristics (shown as spikes in the spectra shape) at 1.25kHz, which is due to `beeper’ type reverse alarms, which is addressed in the noise mitigation strategy within section 6.0. The results show that elimination of the tonal characteristic of the `beeper’ would reduce forklift noise levels by around 3dB(A).



4.0 NOISE POLICY, GUIDANCE AND STANDARDS

4.1 Introduction 4.1.1 Noise has been defined as sound that is unwanted by the recipient. The effects

of noise on the neighbourhood are varied and complicated, including such things as interference with speech communication, disturbance of work, leisure or sleep. A further complicating factor is that in any one neighbourhood some individuals will be more sensitive to noise than others.

4.1.2 In 2000, BRE conducted a national study of environmental noise levels for the

Department of the Environment (`The National Noise Incidence Study 2000’: DEFRA Feb 2002). The study found that 55 (+/- 3%) of the population of England and Wales live in dwellings exposed to day-time noise levels above the WHO level of 55dB LAeq,day. It also found that 63 (+/- 3%) of the population were exposed above the level of 45dB LAeq,night.

4.2 General Planning Guidance

National Planning Policy Framework

4.2.1 Chapter 11 of the National Planning Policy Framework (NPPF) is concerned with the conservation and enhancement of the natural environment. It indicates at paragraph 109 that: “…the planning system should contribute to and enhance the natural environment by:

…Preventing both new and existing development from contributing to or being put at unacceptable risk from, or being adversely affected by unacceptable levels of soil, air, water or noise pollution or land instability…”

4.2.2 Paragraph 123 refers directly to the issue of noise and states that “Planning

policies and decisions should aim to:

Avoid noise from giving rise to significant adverse impacts on health and quality of life as a result of new development;

Mitigate and reduce to a minimum other adverse impacts on health and quality of life arising from noise from new development, including through the use of conditions;

Recognise that development will often create some noise and existing businesses wanting to develop in continuance of their business should not have unreasonable restrictions put on them because of changes in nearby land uses since they were established; and

Identify and protect areas of tranquillity which have remained relatively undisturbed by noise and are prized for their recreational and amenity value for this reason.”

4.2.3 The Noise Policy Statement for England (NPSE) was published in March 2010.

It specifies the following long-term vision in policy aims: “Through the effective management and control of environmental, neighbour and neighbourhood noise within the context of Government policy on sustainable development:

Avoid significant adverse impacts on health and quality of life;

Mitigate and minimise adverse impacts on health and quality of life; and

Where possible, contribute to the improvement of health and quality of life.”



4.2.4 The NPSE introduced three concepts to the assessment of noise, which

includes:

NOEL – No Observed Effect Level This is the level below which no effect can be detected and below which there is no detectable effect on health and quality of life due to noise. LOAEL – Lowest Observable Adverse Effect Level This is the level above which adverse effects on health and quality of life can be detected. SOAEL – Significant Observed Adverse Effect Level This is the level above which significant adverse effects on health and quality of life occur.

4.2.5 The above categories are however undefined in terms of noise levels and for the SOAEL the NPSE indicates that the noise level will vary depending upon the noise source, the receptor and the time of day/day of the week, etc. The need for more research is therefore required to establish what may represent an SOAEL. It is acknowledged in the NPSE that not stating specific SOAEL levels provides policy flexibility until there is further evidence and guidance. The following commentary is given on the representation of NOEL, LOAEL and SOAEL in relation to existing British Standards/ International guidelines: NOEL – Inaudibility LOAEL – The guideline values for community noise in specific environments as set out in table 1 of the WHO Guidelines for Community Noise 1999 and in tables 5 and 6 of BS8233: 1999 - Sound insulation and noise reduction for buildings - Code of Practice.

4.2.6 The NPSE concludes how the LOAEL and SOAEL relate to the three aims

listed in paragraph 4.2.3 above. The initial aim relates to avoiding significant adverse effects on health and quality of life, it then addresses the situation where the noise impact falls between the LOAEL and the SOAEL when: “all reasonable steps should be taken to mitigate and minimise adverse effects on health and quality of life while also taking into account the guiding principles of sustainable development.”

4.2.7 The final aim envisages pro-active management of noise to improve health and quality of life, again taking into account the guiding principles of sustainable development

4.2.8 The Government is undertaking a review of technical guidance but currently there is no agreed methodology for noise to accompany the NPPF guidance.

4.2.9 The Government has removed Planning Policy Guidance on noise, which was

known as PPG24: 1994. The National Planning Policy Framework states “109. The planning system should contribute to and enhance the natural and local environment by:

preventing both new and existing development from contributing to or being put at unacceptable risk from, or being adversely affected by unacceptable levels of soil, air, water or noise pollution or land instability;”



4.2.10 On March 6th 2014 the Government updated the Planning Practice Guidance

(“PPG”) on noise, which provides further information in respect of new developments which may be sensitive to the prevailing acoustic environment.

4.2.11 The PPG includes a table summarising the noise exposure hierarchy, based on

the likely average response. Under the heading of `perception’ the `noticeable and not intrusive’ assessment of noise is defined as `noise can be heard, but does not cause any change in behaviour or attitude, can slightly affect the acoustic character of the area but not such there is a perceived change in the quality of life’. The increasing effect level under these conditions is deemed to be `no observed adverse effect’ and no specific measures are required.

Relevant Guidance & Standards – Fixed Industrial Noise BS 4142: 1997 `Method for rating industrial noise affecting mixed residential

and industrial areas'

4.2.12 BS 4142: 1997 `Method for Rating industrial noise affecting mixed residential and industrial areas’ is based on the measurement of background noise using L

A90 noise measurements, compared to source noise levels measured in L

Aeq

units. The differential between the two measurements; once any corrections have been applied for source noise tonality, distinct impulses etc. (i.e. the `rating’ level); determines the likelihood of complaints. If the resultant `rating’ level has a differential of +5dB(A) above background noise, then the standard says that the noise is of `marginal significance’, if the differential is +10dB(A) then `complaints are likely’. This standard is suitable for assessing fixed noise sources of an industrial nature.

4.2.13 The BS4142 standard is appropriate to fixed industrial noise sources affecting

residential properties and is therefore relevant to this application. Providing the rating level associated with any fixed industrial noise source (at the proposed nearest residential property) is no more than 5dB(A) above background noise (measured in terms of LA90 then this would be a good indication that complaints are unlikely at the development. The EHO advises that ideally the site noise contribution should be aimed at 10dB(A) below typical background noise within the practicalities of site design and layout.

BS8233:2014 `Guidance on sound insulation and noise reduction for buildings’

4.2.14 The British Standard BS8233 provides additional guidance on noise levels

within buildings. These are based on the WHO recommendations and the criteria given in BS8233 for unoccupied spaces within residential properties.

4.2.15 The guidance provided in section 7.7 of BS8233 provides recommended internal ambient noise levels for resting, dining and sleeping within residential dwellings. Table 4.2 provides detail of the levels given in the standard.

Table 4.2: BS8233: 2014 Indoor ambient noise levels for dwellings

Activity Location 07:00 to 23:00 23:00 to 07:00

Resting Dining Sleeping (daytime resting)

Living Room Dining room/area

Bedroom

35 dB LAeq,16hours

40 dB LAeq,16hours

35 dB LAeq,16hours

- -

30 dB LAeq,8hours



4.2.14 The attenuation from an open window, referred to in BS8233: 2014 and other guidance is -10dB(A) to -15dB(A). Therefore, to achieve a ‘good’ design according to the standard, the level outside a living room window would be within the range 40-45dB(A) Leq and for a ‘reasonable’ standard a level of between 50-55dB(A) Leq. For night-time periods a `good’ design within the bedroom would be an external level of between 40dB and 45dB.

World Health Organisation (WHO) Guidelines for Community Noise: April 1999

4.2.15 This document provides further updated information on noise and its affects on

the community. Within the document for noise `In Dwellings’ it states that `To enable casual conversation indoors during daytime, the sound level of interfering noise should not exceed 35dB LAeq. To protect the majority of people from being seriously annoyed during the daytime, the outdoor sound level from steady, continuous noise should not exceed 55dB LAeq on balconies, terraces and in outdoor living areas. To protect the majority of people from being moderately annoyed during the daytime, the outdoor sound level should not exceed 50dB LAeq. Where it is practical and feasible, the lower outdoor sound level should be considered the maximum desirable sound level for new development.”

World Health Organisation (2009) – Night noise guidelines for Europe

4.2.16 The WHO regional office for Europe set up a working group of experts to provide scientific advice to the Member States for the development of future legislation and policy action in the area of assessment and control of night noise exposure. Considering the scientific evidence on the thresholds of night noise exposure indicated by Lnight,outside as defined in the Environmental Noise Directive (2002/49/EC), an Lnight,outside of 40dB should be the target of the night noise guidance (NNG) to protect the public, including the most vulnerable groups such as children, the chronically ill and the elderly. Lnight,outside value of 55dB is recommended as an interim target for the countries where the NNG cannot be achieved in the short term for various reasons, and where policy-makers choose to adopt a stepwise approach.

Construction Noise

4.2.17 For construction noise British Standard BS 5228:2009 is the relevant guidance.

This is an approved code of practice under the Control of Pollution Act and consequently construction noise and vibration is normally controlled according to the recommendations given in BS 5228. The Standard does not give noise limits for construction sites, but emphasis is placed on ensuring that `best practice’ is adopted to control noise and vibration on site.

4.2.18 Noise and vibration emission levels emanating from the Site due to associated

construction works for the Proposed Development is not expected to be significant as there is no proposed additional building construction or significant ground works or infrastructure required. Any works required is expected to be limited to internal fittings to buildings and any building or surface repair work (as required).



Operational Noise – Daytime Hours

4.2.19 Appropriate noise criteria for site operational noise from fixed plant would be BS4142: 1997 ’Method for Rating Industrial Noise Affecting Mixed Residential and Industrial Areas’. This standard gives a method for establishing the likelihood of complaints from noise relating to industrial establishments made by persons living in residential properties.

4.2.20 Following discussion with the Environmental Health Officer (EHO) on other sites in Kettering, it was agreed that BS4142 would be the most appropriate standard for fixed plant noise sources. An appropriate daytime noise criteria as advised by the EHO would relate to a `rating noise level not exceeding background noise levels at the nearest sensitive property based on a 1 hour LAeq (free field conditions) in accordance with BS4142: 1997’.

4.2.21 Considering the measured baseline levels, the following limits would be

considered, which provides a noise limit (i.e. rating level) not exceeding background noise:

Operational Noise – Night-time Hours

4.2.22 In terms of any night-time activity there may be occasional seasonal HGV movement on site and forklift offload of refrigeration plant (i.e. maximum of 3 vehicles per weekend between June and October), which would involve short term activities in the service yard area. The application of BS4142 would not be appropriate for this type of noise source. For night-time vehicular movement we would refer to sleep disturbance criteria for bedrooms with windows open and therefore the following absolute noise limits would be appropriate based on WHO and BS8233: 2014 guidance:

a) <40dB LAeq8hr b) <=57dB LAmax

The above is based on free field measurements outside the dwelling. For the purpose of noise prediction for night-time periods we have assumed a receptor height of 4m above ground level. Road Traffic Noise

4.2.23 The site is designated as industrial and is located on a well-established

industrial estate. The number of HGVs expected to visit the proposed site is not expected to be significant and unlikely to generate any significant change in noise levels onto the local road network that hasn’t already been factored into the forward planning of the industrial estate.



5.0 NOISE LEVEL PREDICTIONS

5.1 Introduction

5.1.1 Noise has been defined as sound, which is undesired by the recipient. The effects of noise on the neighbourhood are varied and complicated, including such things as interference with speech communication, disturbance of work, leisure or sleep. A further complicating factor is that in any one neighbourhood some individuals will be more sensitive to noise than others.

5.1.2 A measure that is in general use and is recommended internationally for the

description of environmental noise is the equivalent continuous noise level or LAeq parameter.

5.1.3 In general, the level of noise in the local environs that arises from a

development site will depend on a number of factors. The more significant of which are: (a) The sound power levels of the plant or equipment used on site. (b) The periods of operation of the plant on site. (c) The distance between the source noise and the receiving position. (d) The presence or absence of screening effects due to barriers, or ground

absorption. (e) Any reflection effects due to the facades of buildings etc.

5.2 Prediction Methodology

Site Operational Noise

5.2.1 For site operational noise we have used ISO9613-2 prediction modelling and

CadnaA software for producing noise maps of the highest likely generated noise.

5.2.2 The methodology takes into account source position, distance and duration of

activity. Any local screening from any existing garden fencing on the intervening ground in relation to the nearest sensitive receptors has not been taken into account, however any existing buildings or proposed screening is included where appropriate. The noise modelling assumes that all significant plant is operating. The ground absorption factor is assumed to be `hard’ ground. The prediction calculations therefore provide an indication of the highest likely noise level.

5.2.3 Predictions for mobile plant movements on site have also been based on the

calculation methodology provided under BS5228: Part 1. We have used CadnaA software prediction modelling for the calculations (refer to Appendix 4 for noise maps).

5.3 Plant Complement

5.3.1 Detail of plant noise levels from which the noise predictions were made are

presented in Section 3.0 and Appendix 3. The plant complement is based on

empirical data from site measurements recorded by NVC at the applicant’s

existing site at Wellingborough under normal operations. The predictions are

therefore as accurate as possible as they utilise actual measured data of

typical activities.



5.4 Results of Noise Predictions

5.4.1 We have used empirical data of the fixed and mobile plant likely to be used for the calculations at the nearest property boundary locations during site operations. Refer to Appendix 3 for further information on site operating noise levels.

5.4.2 The above tables show the highest predicted noise levels from site operations

which are likely to occur during the daytime or occasionally during night-time offloading periods. This is based on measured plant noise during peak noise activities and is therefore the highest likely noise to be generated by the site.

5.4.3 The above would indicate that with the proposed recommendations on noise

control, the levels at residential receptors would indicate that complaint is unlikely. Occasional noise activities at night-time would be below the WHO guidance limit for sleep disturbance and would result in noise levels below the design range according to BS8233: 2014 (allowing for an open window).

LAmax Levels

5.4.4 The predicted LAmax levels during night-time occasional offloading events (based on site measured impact noise from the existing site) with noise mitigation measures ranges between 47dB and 48dB LAmax. These are well below existing LAmax levels at nearest receptor positions due to the influence of local noise sources. The LAmax levels are also well below WHO guidance and BS8233:2014 design limits for internal noise levels within bedrooms with an open window.



6.0 CONCLUSIONS

Background Noise Levels & Noise Criteria

6.1 The results of baseline monitoring show that daytime average background noise levels (i.e. LA90) at the nearest receptors are 48dB during the weekday and 42dB LA90 at the weekend. Average LAeq levels during daytime periods vary typically between 55dB and 58dB.

6.2 The range of LAeq readings during the night-time monitoring periods on Saturday and Sunday (based on 1 hour readings) is shown to be between 39dB and 52dB and average LA90 levels of 32-33dB.

6.3 The application of appropriate guidance and standards has enabled reasonable noise criteria to be adopted for daytime and night-time operations. In accordance with BS4142: 1997 the daytime noise criteria at nearest residential properties would be a site noise contribution not exceeding 48dB(A) Leq1hour during weekday periods and 42dB(A) Leq1hour on Saturdays when measured in accordance with the standard (i.e. minimum of 3.5 metres from reflective building façade, wall or large object). For night-time the protection of sleep is necessary and therefore the appropriate noise criteria would be site noise contribution below a level of 40dB(A) Leq1hour and 57dB LAmax measured in accordance with BS4142: 1997 at nearest residential receptors.

6.4 The operating hours for the development would be between 0700 to 1800

hours Monday to Friday and 0700 to 1400 hours on Saturday. Occasional night-time offloading of refrigeration plant would take place at the eastern end of the site with appropriate noise mitigation measures to ensure residential amenity is protected.

Predicted Site Operational Noise

6.5 At the nearest residential property boundary positions, the highest likely predicted noise levels during daytime operations (without further noise mitigation measures) are calculated to be between 43dB(A) to 48dB(A) Leq1hr

during daytime activities. With the proposed mitigation measures in place, the resultant noise levels fall to a range of 37dB(A) to 46dB(A) Leq1hr. The attenuated levels are below existing background noise levels (i.e. an LA90 level).

6.6 During the occasional night-time offloading of HGVs at the eastern end of the

site the predicted noise levels (without further noise mitigation measures) are calculated to be between 34dB(A) to 42dB(A) Leq5mins during night-time activities. With the proposed mitigation measures in place, the resultant noise levels fall to a range of 32dB(A) to 37dB(A) Leq5mins (43dB to 48dB LAmax). The attenuated levels are therefore below existing background noise levels and below sleep disturbance criteria according to WHO guidance and BS8233: 1999 design limits within bedrooms.



Conclusions

6.7 With the proposed development in operation, without any noise mitigation measures, a BS4142 assessment indicates that the highest weekday daytime noise levels are unlikely to lead to complaint, however during Saturdays without further mitigation noise levels could result in complaint. The implementation of proposed noise control measures show that complaint would then be unlikely at the nearest residential receptors.

6.8 Occasional seasonal offloading of HGVs during night-time periods at the eastern end of the site with the proposed mitigation measures would be within all relevant guidance to protect residential amenity and sleep disturbance criteria.

6.9 Taking into account the hours of operation, the site layout, the noise control

measures proposed, subjective observations of existing ambient noise levels, measured operational noise levels and the relative position of the nearest residential properties to the noise source, it is our expert opinion that resultant noise level would comply with appropriate and relevant guidance and standards and would provide adequate protection for residential amenity.

Road Traffic Noise

6.10 The site is designated as industrial and is located on a well-established

industrial estate. The number of HGVs expected to visit the proposed site is not expected to be significant and unlikely to generate any significant change in noise levels onto the local road network that hasn’t already been factored into the forward planning of the industrial estate.

Construction Noise

6.11 Noise and vibration emission levels emanating from the Site due to associated

construction works for the Proposed Development is not expected to be significant as there is no proposed additional building construction or significant ground works or infrastructure required. Any works required is expected to be limited to internal fittings to buildings and any building or surface repair work (as required). Best practice would be applied for any construction work undertaken in accordance with BS5228: 2009 `Code of practice for noise and vibration control on construction and open sites’



7.1 NOISE MITIGATION

7.2 Construction Noise:

7.2.1 In accordance with BS5228, the contractor shall follow best practicable means to reduce the noise impact upon the surroundings during construction work – this will include the following:

Proper use of plant with respect to minimising noise emissions and regular maintenance.

All vehicles and mechanical plant used for the purpose of the works should be fitted with effective exhaust silencers and should be maintained in good efficient working order.

Selection of inherently quiet plant where appropriate. All major compressors should be ‘sound reduced’ models fitted with properly lined and sealed acoustic covers which should be kept closed whenever the machines are in use and all ancillary pneumatic percussive tools should be fitted with mufflers or silencers of the type recommended by the manufacturers.

Machines in intermittent use should be shut down in the intervening periods between work or throttled down to a minimum.

All ancillary plant such as generators, compressors and pumps should be positioned so as to cause minimum noise disturbance. If necessary, acoustic enclosures should be provided; and

Adherence to the codes of practice for construction working given in British Standard BS5228 and the guidance given there in minimising noise emissions from the site. Where excessive noise levels are predicted at any sensitive receptor, alternative methods of construction shall be investigated for that particular routine, and alternative plant and working routines formulated if necessary.

7.2.2 In any case, the Contractor must adopt the Best Practical Means (BPM) as

defined in the Control of Pollution Act 1974 (CoPA) in order to control and reduce noise from construction activities. The Contractor will have as minimum requirement to implement the BPM measures.

7.3 Industrial Noise

7.3.1 The Local Authority is able to set out planning consent conditions to ensure that appropriate noise levels for daytime and night-time operations is achieved.

7.3.2 Whilst this can be achieved by mitigation it must be noted that this

assessment considers one method of treatment. There are a number of different ways in which the criteria can be achieved, for example, the use of noise control at source and/or the selection of different plant equipment, which may be quieter, can be investigated to meet the noise criteria [i.e. by applying Best Practicable Means].

7.3.3 The predicted noise levels from the site have been calculated with the

proposed noise mitigation measures, site layout and operations to ensure that the resultant noise levels are within appropriate guidance and standards.



7.4 Example of Noise Mitigation Measures

7.4.1 The following provides an example of noise mitigation measures that would achieve the noise criteria.

Proposed Noise Control Measures

7.4.2 As part of the site development and operation, the following noise

control measures is proposed to control noise radiating from the site:

Daytime Weekday Activities:

(i) Where practicable, provision of HGV turning circles to minimise the use of reversing alarms.

(ii) All mobile plant used on site would be fitted with broadband type noise reverse alarms (i.e. non-`beeper’ type e.g, Brigade Electronics `smart alarms’ ) or non-audible warning subject to health and safety requirements.

(iii) All processing of recyclables to be carried out within a building and during the use of powered tools, compressor or fixed plant, the doors into the building would be closed except one door at each end of the building (i.e. door furthest from the northern boundary) for access to mobile plant and vehicles during loading and removal of material and for maintenance and emergency.

(iv) All existing roller doors to have any holes or repairs done to ensure there is no significant acoustic leakage.

(v) Any non-insulated existing roller doors to be `blanked-off’ using additional insulation and timber plywood (e.g. 12mm-15mm boards) retaining inner layer.

Daytime Saturday Activities:

(i) Where practicable, provision of HGV turning circles to minimise the use of reversing alarms.

(ii) All mobile plant used on site would be fitted with broadband type noise reverse alarms (i.e. non-`beeper’ type e.g, Brigade Electronics `smart alarms’ ) or non-audible warning subject to health and safety requirements.

(iii) All processing of recyclables to be carried out within a building and during the use of powered or hand tools, compressor or fixed plant, the doors into the building would be k ep t closed. During periods when the doors are required to be opened for loading or offloading no plant or tools would be operating.

(iv) All existing roller doors to have any holes or repairs done to ensure there is no significant acoustic leakage.

(v) Any non-insulated acoustic doors to be `blanked-off’ using additional insulation and timber plywood (e.g. 12mm-15mm boards) retaining inner layer.

(vi) A screen would be created running parallel with the northern boundary from the northeast corner of the processing building across the service yard would be required. For example, formed by a group of four 8ft x 40ft containers (i.e. 2 containers high x 2 containers wide) to provide an acoustic screen. Refer to Figure 2 which shows the screen location.



Occasional night-time offloading activities

(i) No processing or operation of plant or tools would be undertaken on site.

(ii) A screen would be created running parallel with the northern boundary from the northeast corner of the processing building across the service yard would be required. For example, formed by a group of four 8ft x 40ft containers (i.e. 2 containers high x 2 containers wide) to provide an acoustic screen. Refer to Figure 2 which shows the screen location. The HGV would park as close as practicable to the screen as shown on noise map **.

(iii) All reverse alarms would be disabled during any night-time offloading for forklift trucks or HGVs.

Site Management:

7.4.3 Driver’s of HGVs or mobile plant should be instructed to avoid leaving engines running or excessive revving of engines.

7.4.4 Where forklift trucks or grab cranes are being used to move waste,

driver’s instructed to avoid unnecessary scraping, dropping of waste material to minimise impact noise with the floor.

7.4.5 Introduction and use of turning circles and/or banksman should be

considered to avoid or minimise the need for reverse alarms.

7.4.6 The maintenance and repair of the service yard area is important to ensure the route of forklift trucks to and from HGVs, buildings and stock areas is as smooth as practicable to minimise impact noise.

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

integration over the measurement period.

Aeq

by electronic

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 LA90 parameter is the noise level exceeded

for 90% of the 15 minute period, i.e. 13.5 minutes. The LA50 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.

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.

LAeq: 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.

LA10,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 LA10 reading was say 60dB, then this means that

for 1 hour out of 10 the level went above 60dB.



LA90,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 LA90 reading was say 50dB, then this means that for 9

hours out of 10 the level went above 50dB.

LAmax: 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
