1 Introduction
1.1 This chapter provides an assessment of the noise and vibration immissions1 from the construction and operation of the proposed ‘Incinerator Bottom Ash’ (IBA) Recycling Facility, located at Ridham Dock, Kent.
1.2 The facility would have a throughput capacity of up to 400,000 tonnes per annum. The operation would entail the importation of non-hazardous IBA by HGV, commencing initially at a throughput of approximately 137,500 tonnes per annum and being derived from the nearby Kemsley Sustainable Energy Plant (SEP).
1.3 The assessment has been undertaken based upon appropriate information on the proposed development provided by the project team. The RPS Acoustics Team is a member of the Association of Noise Consultants (ANC), the representative body for acoustics consultancies, having demonstrated the necessary professional and technical competence. The assessment has been undertaken with integrity, objectivity and honesty in accordance with the Code of Conduct of the Institute of Acoustics (IOA) and ethically, professionally and lawfully in accordance with the Code of Ethics of the ANC.
1.4 The technical content of this assessment has been provided by RPS personnel, all of whom are corporate (MIOA) or non-corporate, associate members (AMIOA) of the IOA (the UK's professional body for those working in acoustics, noise and vibration). Personnel and individual qualifications are provided within the Quality Management table at the start of this chapter and in Appendix A in accordance with the requirement of Section 12 of British Standard (BS) 4142:2014+A1:2019 ‘Methods for rating and assessing industrial and commercial sound’ [1].This chapter has been peer reviewed within the RPS team to ensure that it is technically robust and meets the requirements of our Integrated Management System.
Scope of Study
1.5 This chapter sets out the approach to the assessment; provides a description of the baseline noise environment; identifies those aspects of the proposed development that may result in significant noise and/or vibration effects; provides predictions of noise and/or vibration immissions at the nearest noise and vibration sensitive receptors (NVSRs); and provides an assessment of the significance of noise and/or vibration effects. Mitigation measures are identified where necessary.
1 'Immission' is the correlative of 'emission'. Immission describes the sound received by a noise sensitive receptor whilst emission describes the sound leaving or being emitted by a source.
11055e_NVChapter_Rev1 | 22/11/2019 Page 1 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
Cumulative noise and/or vibration effects with other proposed developments that may also affect the same NVSRs as the project are also considered, as are the limitations of the assessment.
1.6 Significant noise exposure can cause annoyance and sleep disturbance, both of which can impact on health and quality of life (HQL). Significant groundborne vibration can reduce the HQL and working efficiency of building occupants and, for very high levels, has the potential to cause cosmetic or structural damage to buildings and structures.
1.7 This assessment considers noise effects during the construction phase, together with noise arising from operation of the proposed facility. Noise effects from construction and operational traffic on the public highway are also assessed.
1.8 The plant and equipment associated with the construction and operation of the facility would not produce high levels of vibration2 offsite, although the use of some items of fixed plant, such as screeners, may generates some local vibration. On the basis that high vibration levels would not be generated and that vibration levels drop off rapidly with distance, vibration effects from the construction and operation of the proposed facility are scoped out of this assessment.
1.9 The study area for this assessment includes the nearest existing and proposed ‘noise sensitive receptors’ (NSRs) to the site, namely residential dwellings located on the north-eastern part of Iwade village, 1.5 km west of the proposed development site.
1.10 In addition to the above human NSRs, there are ecological NSRs located near to the proposed facility, namely The Swale ‘Special Protection Area’ (SPA), Ramsar site and Site of Special Scientific Interest (SSSI). The nearest ecological designations begin approximately 30 m east of the site.
1.11 An assessment of potential noise effects on these ecological NSRs forms part of the Ecology and Nature Conservation Chapter. However, this chapter details the results of baseline surveys undertaken to quantify the baseline acoustic environment at the ecological NSRs and provides predicted noise levels at the ecological NSRs during the construction and operation of the proposed IBA facility.
1.12 A plan indicating the locations of the above human and ecological NSRs is provided in Figure 1.
2 Construction piling will be undertaken with a ‘continuous flight auger’ (CFA) method, rather than percussive/impact method. The CFA method generally has much lower vibration emissions than any percussive/impact method.

2 Legislation and Policy Context
2.1 This section summarises legislation and policies that are directly relevant to noise and vibration issues.
Legislation
Control of Pollution Act, 1974 2.2 Part III of the Control of Pollution Act 1974 (CoPA) [2] is specifically concerned with pollution. With regard to noise, it covers (where not now subsequently covered by the Environmental Protection Act 1990): construction sites; noise in the street; noise abatement zones; codes of practice and best practicable means (BPM).
2.3 The Control of Noise (Code of Practice for Construction and Open Sites) (England) Order 2015 [3] approved British Standard (BS) 5228-1:2009+A1:2014 [4] and BS 5228-2:2009+A1:2014 [5] for the purpose of giving guidance on appropriate methods for minimising noise from construction and open sites in exercise of the powers conferred on the Secretary of State by sections 71(1)(b), (2) and (3) of the CoPA.
2.4 The CoPA enables the local authority, in whose area work is going to be undertaken, or is being undertaken, the power to serve a notice imposing requirements as to the way in which construction works are to be carried out. This notice can specify the plant or machinery that is or is not to be used, the hours during which the construction work can be carried out, the level of noise and vibration that can be emitted from the premises in question or at any specified point on these premises or that can be emitted during specified hours, or for any change of circumstances.
2.5 Section 61, Part III of the CoPA refers to prior consent for work on construction sites. It provides a method by which a contractor can apply for consent to undertake construction works in advance. If consent is given, and the stated method and hours of work are complied with, including BPM, then the local authority cannot take action under Section 60.
2.6 Section 71, Part III of the CoPA refers to the preparation and approval of codes of practice for minimising noise.
2.7 Section 72, Part III of the CoPA refers to Best Practicable Means, which is defined as:
“reasonably practicable, having regards among other things to local conditions and circumstances, to the current state of technical knowledge and to the financial implications’. Whilst ‘Means’ includes ‘the design, installation, maintenance and manner and periods of operation of plant and machinery, and the design, construction and maintenance of buildings and acoustic structures”.
11055e_NVChapter_Rev1 | 22/11/2019 Page 3 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
2.8 If Best Practicable Means is applied, it can provide a defence in the event of legal action by a complainant.
Environmental Protection Act 1990, Part lll (EPA) 2.9 The Environmental Protection Act 1990 (EPA) [6] deals with statutory nuisance, including noise.
2.10 Section 79, Part III of the EPA, ‘Statutory nuisances and inspections therefor’, places a duty on local authorities to regularly inspect their areas to detect whether statutory nuisances exist. This section also considers and defines the concept of ‘Best Practicable Means’ (BPM) which originates from Section 72, Part III of the CoPA [7], where BPM is defined as:
“reasonably practicable having regard, among other things, to local conditions and circumstances, to the current state of technical knowledge and to the financial implications”.
2.11 Where the local authority is satisfied that a statutory nuisance does exist, or is likely to occur or recur, it must serve an abatement notice. Section 80, Part III of the EPA, ‘Summary proceedings for statutory nuisances’, provides local authorities with the power to serve an abatement notice requiring the abatement of the nuisance or prohibiting or restricting its occurrence or recurrence; and/or carrying out such works or other action necessary to abate the nuisance.
2.12 Section 82, Part III of the EPA, ‘Summary proceedings by persons aggrieved by statutory nuisances’, allows a Magistrates’ court to act on a complaint made by any person on the grounds that he is aggrieved by a statutory nuisance, such as noise.
2.13 The procedures for appeals against abatement notices are detailed in the Statutory Nuisance (Appeals) Regulations 1995.
National Policy and Guidance
National Planning Policy Framework (2019) 2.14 The National Planning Policy Framework (NPPF) [8] sets out the Government’s planning policies for England and how these are expected to be applied. The emphasis of the Framework is to allow development to proceed where it can be demonstrated to be sustainable. In relation to noise, Paragraph 180 of the Framework states:
“Planning policies and decisions should ensure that new development is appropriate for its location taking into account the likely effects (including cumulative effects) of pollution on health, living conditions and the natural environment, as well as the potential sensitivity of the site or the wider area to impacts that could arise from the development. In doing so they should:
11055e_NVChapter_Rev1 | 22/11/2019 Page 4 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
a) mitigate and reduce to a minimum potential adverse impacts resulting from noise from the development – and avoid noise giving rise to significant adverse impacts on health and the quality of life;
b) identify and protect tranquil areas which have remained relatively undisturbed by noise and are prized for their recreational and amenity value for this reason; and
c) limit the impact of light pollution from artificial light on local amenity, intrinsically dark landscapes and nature conservation.”
2.15 The point ‘a)’ refers to ‘significant adverse impacts’ which relates to the ‘significant observed adverse effect level’ (SOAEL) in the Noise Policy Statement for England (NPSE) [9], although the term ‘effect’ is used instead of the term ‘impact’. However, these have been deemed to be interchangeable in this context. Therefore, given the comments above on the NPSE with regard to assessment methods and criteria, the current content of the NPPF does not require any change in previously adopted approaches.
Noise Policy Statement for England 2.16 The NPSE, published in March 2010 by Defra, aims to provide clarity regarding current policies and practices to enable noise management decisions to be made within the wider context, at the most appropriate level, in a cost-effective manner and in a timely fashion.
2.17 Paragraph 1.6 of the NPSE sets out the long-term vision and aims of Government noise policy:
“Noise Policy Vision
Promote good health and a good quality of life through the effective management of noise within the context of Government policy on sustainable development.”
“Noise 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.”
2.18 The aims require that all reasonable steps should be taken to avoid, mitigate and minimise adverse effects on health and quality of life whilst also taking into account the guiding principles of sustainable development, which include social, economic, environmental and health considerations.
11055e_NVChapter_Rev1 | 22/11/2019 Page 5 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
2.19 With regard to the terms ‘significant adverse’ and ‘adverse’ included in the ‘Noise Policy Aims’, these are explained further in the ‘Explanatory Note’ as relating to established concepts from toxicology that are currently being applied to noise impacts, for example, by the World Health Organisation which are:
“NOEL – No Observed Effect Level
This is the level below which no effect can be detected. In simple terms, below this level, there is no detectable effect on human health and quality of life due to noise.
LOAEL – Lowest Observed Adverse Effect Level
This is the level above which adverse effects on health and quality of life can be detected.”
2.20 Defra has then extended these concepts for the purpose of the NPSE to introduce the concept of:
“SOAEL – Significant Observed Adverse Effect Level
This is the level above which significant adverse effects on health and quality of life occur.”
2.21 The accompanying explanation states:
“It is not possible to have a single objective noise-based measure that defines SOAEL that is applicable to all sources of noise in all situations. Consequently, the SOAEL is likely to be different for different noise sources, for different receptors and at different times. It is acknowledged that further research is required to increase our understanding of what may constitute a significant adverse impact on health and quality of life from noise. However, not having specific SOAEL values in the NPSE provides the necessary policy flexibility until further evidence and suitable guidance is available”.
2.22 With regards to ‘further evidence’, Defra has commissioned research to try and identify the levels at which the above effects occur. However, this research has been largely inconclusive and varies with source. On this basis, and until further guidance becomes available, and given that there is no specific guidance in the NPPF on noise, there is no justification to vary assessment methods and criteria from those previously adopted from British Standards etc.
Planning Practice Guidance 2.23 In addition to the NPPF and the NPSE, the Department for Communities and Local Government has released National Planning Practice Guidance (NPPG) [10]. The NPPG provides guidance on determining the significance of noise effects to support the requirements of the NPPF.
2.24 The guidance provides advice on how to deliver its policies. The NPPG reiterates general guidance on noise policy and assessment methods provided in the NPPF, NPSE and British Standards and
11055e_NVChapter_Rev1 | 22/11/2019 Page 6 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
contains examples of acoustic environments commensurate with various effect levels (paragraph Reference ID: 30-001-20140306).
2.25 The NPPG describes noise that is not noticeable to be at levels below the NOEL. It describes a range of noise exposure that is noticeable but not to the extent there is a perceived change in quality of life. Noise exposures in this range are below the LOAEL and need no mitigation. On this basis, the audibility of noise from a development is not, in itself, a criterion to judge noise effects that is commensurate with national planning policy.
2.26 The NPPG suggests that noise exposures above the LOAEL cause small changes in behaviour. An example of noise exposures above the LOAEL provided in the PPG is having to turn up the volume on the television; needing to speak more loudly to be heard; or, where there is no alternative ventilation, closing windows for some of the time because of the noise. In line with the NPPF and NPSE, the NPPG states that consideration needs to be given to mitigating and minimising effects above the LOAEL but taking account of the economic and social benefits being derived from the activity causing the noise.
2.27 The NPPG suggests that noise exposures above the SOAEL cause material changes in behaviour. An example of noise exposures above the SOAEL provided in the NPPG are, where there is no alternative ventilation, keeping windows closed for most of the time or avoiding certain activities during periods when the noise is present. In line with the NPPF and NPSE, the NPPG states that effects above the SOAEL should be avoided and that whilst the economic and social benefits being derived from the activity causing the noise must be taken into account, such exposures are undesirable.
National Planning Policy for Waste 2.28 Appendix B of the National Planning Policy for Waste (NPPW) [11] provides a list of factors that are to be considered in determining planning applications including:
“j. noise, light and vibration Considerations will include the proximity of sensitive receptors. The operation of large waste management facilities in particular can produce noise affecting both the inside and outside of buildings, including noise and vibration from goods vehicle traffic movements to and from a site. Intermittent and sustained operating noise may be a problem if not properly managed particularly if night-time working is involved. Potential light pollution aspects will also need to be considered.”
11055e_NVChapter_Rev1 | 22/11/2019 Page 7 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
Local Policy and Guidance
Kent Minerals and Waste Local Plan 2013-30 2.29 The Kent Minerals and Waste Local Plan 2013-30 (KMWLP) [12] was adopted in July 2016 and sets out the vision and strategy for waste management and mineral provision up until the year 2030. It also contains a number of development management policies for evaluating minerals and waste planning applications. Policy DM 11 ‘health & Amenity’ relates specifically to noise and states:
“Minerals and waste development will be permitted if it can be demonstrated that they are unlikely to generate unacceptable adverse impacts from noise, dust, vibration, odour, emissions, bioaerosols, illumination, visual intrusion, traffic or exposure to health risks and associated damage to the qualities of life and wellbeing to communities and the environment. This may include production of an air quality assessment of the impact of the proposed development and its associated traffic movements and necessary mitigation measures required through planning condition and/or planning obligation. This will be a particular requirement where a proposal might adversely affect the air quality in an AQMA.
Proposals for minerals and waste development will also be required to ensure that there is no unacceptable adverse impact on the use of other land for other purposes.”
2.30 In addition, Ridham Dock is classified as a ‘Safeguarded Wharf’ and, as such, Policy CSM 6 ‘Safeguarded Wharves and Rail Depots’ of the KMWLP is also relevant with regard to this assessment, as it states:
“Planning permission will not be granted for non-minerals development that may unacceptably adversely affect the operation of existing, planned or potential sites, such that their capacity or viability for minerals transportation purposes may be compromised.”
Consultation
2.31 No formal consultation process has been undertaken other than the Screening Request submitted for the development and the Screening Opinion subsequently issued by Kent County Council which stated that, with regards to noise:
“Development of the site has the potential to cause impacts from noise and air quality/dust upon the nearby sensitive ecological interests as well as neighbouring industrial users. Any application would need to have regard to this and address potential impacts, including those in relation to any increase in HGV movements. This is likely to require technical reports on noise, dust and air quality to support the application. As a general guide, best practice suggests that an increase in HGV movements by more than 100 per day would trigger the need for an air quality assessment.
11055e_NVChapter_Rev1 | 22/11/2019 Page 8 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
Any noise assessment should consider existing, permitted and predicted noise impacts and address a worse-case scenario that provides for the full range of operations proposed (including the cumulative impact of all plant and equipment that would be used on site, HGVs entering and leaving the site during core operational hours). You may wish to look into appropriate noise attenuation measures which may include containing activities within a building which offers containment of such impacts (as well as opportunities for other amenity controls). Any assessment should consider the proposals in the context of its industrial location; however, it should also assess the wider noise impacts from traffic on any residential receptors on the access routes. It should also consider impacts upon the adjacent designated nature conservation sites.”
2.32 In addition, Natural England (NE) has been consulted as the proposed IBA facility would be located close to The Swale ‘Special Protection Area’ (SPA), Ramsar and ‘Site of Special Scientific Interest’ (SSSI) sites. With regards to noise, NE has stated that:
“Disturbance to birds using the adjacent intertidal and reedbed habitat could occur during the construction and operation of the IBA facility, including from noise, visual intrusion and lighting. I advise that, rather than using a threshold approach to assessing the impact of noise, a potentially more suitable approach is to assess the change in noise levels, both continuous noise and sporadic. A difference of 3 dBA in similar types of noise is just distinguishable to people, so it is reasonable to assume that if the change in noise is no more than 3dB it is unlikely to be significant.”
2.33 Furthermore, NE has recommended that construction impacts from the IBA facility are minimised by using non-percussive piling methods. Information provided by the project team confirms that piling will be undertaken with the CFA method, as previously mentioned, rather than any percussive/impact method.
2.34 As noted in paragraph 1.11 potential noise effects at the SPA, Ramsar and SSSI are considered in the Ecology and Nature Conservation Chapter. This noise and vibration chapter details the results of baseline surveys undertaken to quantify the baseline acoustic environment at the ecological NSRs and provides predicted noise levels at the ecological NSRs during the construction and operation of the proposed IBA Facility.

3 Assessment Methodology
3.1 The assessment methodology has been informed by guidance contained within the following documents:
• BS 5228-1:2009+A1:2014. Code of practice for noise and vibration control on construction and open sites - Part 1: Noise;
• BS 5228-1:2009+A1:2014. Code of practice for noise and vibration control on construction and open sites - Part 2: Vibration;
• BS 4142:2014+A1:2019. Methods for rating and assessing industrial and commercial sound;
• Guidelines for Community Noise (GCN) [13];
• ISO 9613-2:1996. Acoustics - Attenuation of sound during propagation outdoors - Part 2: General method of calculation [14];
• Calculation of Road Traffic Noise (CRTN) [15]; and
• Design Manual for Roads and Bridges (DMRB). Volume 11. Section 3 - Part 7: Noise and Vibration [16].
Baseline Surveys
3.2 One long term seven-day baseline sound level survey was undertaken at the nearest residential NSR to the site of the proposed facility between Tuesday 8th October and Tuesday 15th October 2019.
3.3 The long-term survey (LT1) was located at a dwelling on Swallow Avenue, Iwade, the nearest residential NSR to the proposed facility. The microphone was mounted on a pole secured to the front garden fence at a height of approximately 2.5 metres above local ground level in a free-field location. During the time spent on site setting up the long-term survey, the following sound sources were noted: distant road traffic movements, occasional aircraft passing overhead and general neighbourhood noise.
3.4 In addition, a short-term attended survey was undertaken on the Elmley Nature Reserve site between 12:40 and 13:20 hours on Tuesday 15th October 2019.
3.5 A plan showing the approximate location of the measurement positions and site boundary is provided in Figure 1.
3.6 Due to access requirements, the short-term survey was undertaken at a location on the Elmley Nature Reserve site further east from the proposed facility site. Had the survey been undertaken on the Elmley Nature Reserve site closer to the proposed site, baseline sound levels measured
11055e_NVChapter_Rev1 | 22/11/2019 Page 10 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
would have been higher due to the closer proximity of the A249 Road and other existing land uses within the Ridham Dock area. As such, the subsequent assessment is based on a robust and precautionary baseline level as the likelihood for potential impact is greater for when baseline levels are lower.
3.7 All sound level measurements were made using ‘Class 1’ Rion NL-52 sound level meters (SLM) in accordance with BS 7445-2:1991 [17]. Both SLMs were calibrated before and checked after use with a Rion NC-74 calibrator with no significant drift occurring.
3.8 Meteorological data were logged with a rain gauge and anemometer at the location of the long- term survey. The survey period was largely dry and with low wind speeds, although there were two, 24-hour periods during which rainfall and/or high wind speeds were logged (between 12:00 hours on 12th October through to 12:00 hours on 13th October and all of the 14th October).
3.9 Analysis of the data also indicates that these periods corresponded to higher measured noise levels. As such, these two 24-hour periods of data have been removed from the subsequent analysis on the basis that these are not representative.
3.10 Meteorological conditions during the short-term survey were dry and calm, with a light westerly wind (below 5 m/s).
3.11 Further survey data and information is provided in Appendix B.
Assessment Criteria and Assignment of Significance
3.12 The assessment of significance for each aspect of the development (construction and operation) has been determined from the NSR sensitivity and magnitude of impact based on the following matrix.
Table 3.1 Assessment Matrix for the Determination of the Significance of Effect
Sensitivity Magnitude of Impact of Receptor No Change Negligible Low Medium High Negligible or Negligible or Negligible None Negligible Minor Minor Minor Negligible or Negligible or Minor or Low None Minor Minor Minor Moderate Negligible or Moderate or Medium None Minor Moderate Minor Major Minor or Moderate or Major or High None Minor Moderate Major Substantial Moderate or Major or Very high None Minor Substantial Major Substantial
11055e_NVChapter_Rev1 | 22/11/2019 Page 11 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
3.13 With reference to Table 3.1 above the significance of noise effect is a function of both the sensitivity of the NSR affected and the magnitude of the noise impact at that NSR (e.g. change in noise level as a result of the new development). On this basis, for a given sensitivity of NSR, the significance of noise effect is directly linked to the magnitude of impact.
3.14 Where the matrix offers more than one significance option, professional judgement has been used to decide which option is most appropriate.
3.15 The broad definitions of the terms above are as follows:
• Substantial: These effects represent key factors in the decision-making process. These effects are generally, but not exclusively, associated with sites or features of international, national or regional importance that are likely to suffer a most damaging impact and loss of resource integrity. However, a major change in a site or feature of local importance may also enter this category.
• Major: These effects are considered to be very important considerations and are likely to be material in the decision-making process.
• Moderate: These effects may be important but are not likely to be key decision-making factors. The cumulative effects of such factors may influence decision-making if they lead to an increase in the overall adverse effect on a particular resource or receptor.
• Minor: These effects may be raised as local factors. They are unlikely to be critical in the decision-making process but are important in enhancing the subsequent design of the project.
• Negligible: No effects or those that are beneath levels of perception, within normal bounds of variation or within the margin of forecasting error.
3.16 In general, only effects that are moderate and above are considered to be significant in terms of the EIA Regulations in this assessment.
3.17 Outlined below is consideration of the sensitivity of the NSRs potentially affected by the construction and operation of the proposed IBA Facility and how the magnitude of noise impacts associated with the construction and operation of the IBA Facility are determined.
Sensitivity of Receptors
3.18 Table 3.2 below provides the thresholds used within this assessment for determining the sensitivity of noise and vibration receptors.

3.19 For this assessment, all NSRs are considered as medium sensitivity (residential dwellings). As such, there is a direct link between the magnitude of impact associated with the construction/operation of the IBA facility and the significance of effect. This is summarised in Table 3.3 below.

Construction Noise: On-Site Construction Works 3.20 The magnitude of construction noise impacts has been determined in accordance with Annex E of BS 5228-1:2009+A1:2014. The significance criteria for assessing noise impact from construction works have been based on Example Method 2 contained within Annex E.3.3 of BS 5228-1:2009+A1:2014, as referred to above. This indicates that:
“Noise levels generated by site activities are deemed to be potentially significant if the total noise (pre-construction ambient plus site noise) exceeds the pre-construction ambient noise by 5 dB or
more, subject to lower cut-off values of 65 dB, 55 dB and 45 dB LAeq period, from site noise alone, for the daytime, evening and night-time periods, respectively; and a duration of one month or more, unless works of a shorter duration are likely to result in significant effect.”
3.21 For the majority of NSRs, pre-construction ambient noise levels are relatively low, resulting in the criteria set within the lower cut-off levels given in Table 3.4 below applying, the most stringent limits. As such, the lower cut-off levels are used throughout the construction assessment. The assessment also applies the duration criteria in BS 5228-1:2009+A1:2014 of works taking place for one month or more.

3.22 It should be noted that construction works are programmed to occur during normal construction times only, i.e. 07.00 to 19.00 hours on weekdays and 07.00 to 13.00 hours on Saturdays.
3.23 With reference to paragraph 3.19, for this assessment all NSRs are considered as medium Based on information provided by the client team, it is anticipated that the nosiest phase of the construction works with most noise generating plant in use will be site clearance and the foundation construction phase.
3.24 Table 3.5 below summarises the plant items will be used during this phase, with associate sound power levels (SWLs) based on information provided in BS 5228-1:2009+A1:2014.

3.26 It should be noted that construction plant items noted in Table 3.3 have been assumed to be in use for 100% of the assessment period. Such an approach will allow for an assessment of a ‘worse- case scenario’. It is considered very likely that construction activity would not be undertaken for 100% of the time concurrently and, therefore, noise levels in reality would be lower than those predicted and assessed.
11055e_NVChapter_Rev1 | 22/11/2019 Page 14 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
3.27 On the basis of the above, sound levels associated with the construction of the facility have been predicted at the NSRs defined in the study area using SoundPLAN Version 8.1 sound modelling software utilising the propagation method contained in ISO 9613-2:1996.
3.28 The following assumptions have been incorporated into the noise model:
• the topography of the site and the surrounding area has been obtained from site surveyed topographical data and Ordnance Survey (OS) open data (Terrain 50);
• the effect of screening from solid structures (buildings) has been incorporated into the modelling process by importing OS Open Data ‘Settlement Area’ shape file data into the model; and
• the ground type in the model has been set to hard for the site (G=0) and soft for the wider area (G=1).
Construction Noise Impacts: Off-site Construction Traffic 3.29 Based on information provided by the project team, up to 25 construction HGVs will arrive/depart from the construction site per day (concrete delivery / muck removal etc.)
3.30 The assessment of changes in road traffic noise levels on local roads as a result of the construction of the proposed development is based on the methods contained within the DMRB, which is a method designed for the assessment of new construction, improvements and maintenance of trunk roads. Therefore, the method described in the DMRB is considered as informative but not definitive for the assessment of the traffic noise effects arising from traffic generation associated with the proposed development.
3.31 Further details of the traffic noise assessment are provided within the methodology set out below for assessment of operational off-site road traffic noise, with thresholds of impact magnitude provided in Table 3.8.
Operational Noise Impacts: Operation of the Proposed Facility 3.32 The foreword to BS 4142:2014+A1:2019 provides the following introduction for the assessment of human response to sound:
“Response to sound can be subjective and is affected by many factors, both acoustic and non- acoustic. The significance of its impact, for example, can depend on such factors as the margin by which a sound exceeds the background sound level, its absolute level, time of day and change in the acoustic environment, as well as local attitudes to the source of the sound and the character of the neighbourhood.”
3.33 BS 4142:2014+A1:2019 primarily provides a numerical method by which to determine the significance of sound of an industrial nature (i.e. the ‘specific sound’ from the proposed
11055e_NVChapter_Rev1 | 22/11/2019 Page 15 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
development) at residential NSRs. The specific sound level may then be corrected for the character of the sound (e.g. perceptibility of tones and/or impulses), if appropriate, and it is then termed the ‘rating level’, whether or not a rating penalty is applied. The ‘residual sound’ is defined as the ambient sound remaining at the assessment location when the specific sound source is suppressed to such a degree that it does not contribute to the ambient sound.
3.34 The specific sound levels have been determined separately in terms of the LAeq,T index over a period of T = 1 - hour during the daytime and T = 15 - minutes during the night-time. For the purposes of the Standard, daytime is typically considered to be the period between 07:00 and 23:00 hours and night-time is typically between 23:00 and 07:00 hours and these hours have been adopted for this assessment.
3.35 The processing plant consists of a feed hopper and an arrangement of modular plant comprising conveyors, trommel, magnets, eddy current separators and screens to process the IBA into saleable aggregates and recover metals. Processing will predominantly take place within clad, steel portal-framed buildings, except for external conveyors transferring material between housings. A 2.1 m high reinforced concrete flood defence/retaining wall will be located on the perimeter of the site.
3.36 The processing of IBA would take place 24 hours a day, seven days a week. HGV deliveries would take place during the hours of 06:00 to 19:00 six days a week.
3.37 For the purposes of this assessment, in accordance with BS 4142:2014+A1:2019, it has been assumed that full site operations including HGVs and other external mobile plant would take place during the daytime and night-time periods, despite HGV movements only occurring during the night- time period of between 06:00 and 07:00 hours.
3.38 Specific sound levels associated with site operations have been predicted at NSRs using SoundPLAN Version 8.1 sound modelling software utilising the propagation method contained in ISO 9613-2:1996
3.39 Source data and dimensions of proposed buildings for the facility have been supplied by the project team, and from data provided within BS 5228-1:2009+A1:2014 where appropriate. Operational noise sources modelled are summarised in Table 3.6 below.

3.41 Note that the front-end loader and 360 slew have been modelled as area sources across the site (on the basis that these will not be fixed and would be moving around) @ 2 m AGL3 and HGV movements as a line source at 2 m AGL. Buildings have been modelled as industrial buildings with the above indicated internal noise level and have been modelled as clad using a standard Kingspan
panel (sound insulation value of 25 dB Rw).
3.42 It should be noted that all operational plant and activities noted in Table 3.4 have been modelled as being in use for 100 % of the time to allow for an assessment of a ‘worse-case scenario’.
3.43 The following assumptions have been incorporated into the noise model:
• the topography of the site and the surrounding area has been obtained from site surveyed topographical data and OS open data (Terrain 50);
• the effect of screening from solid structures (buildings) has been incorporated into the modelling process by importing OS Open Data ‘Settlement Area’ shape file data into the model; and
• the ground type in the model has been set to hard for the site (G = 0) and soft for the wider area (G = 1).
3.44 Predictions have been made at ground floor level for the daytime period and first floor level for the night-time period.
3.45 An initial estimate of the impact of the specific sound has been obtained by subtracting the measured background sound level (detailed in Section 5 below) from the rating level. In the context of the Standard, adverse impacts include, but are not limited to, annoyance and sleep disturbance. Typically, the greater this difference, the greater is the magnitude of the impact defined in the Standard as follows:
• A difference of around +10 dB or more is likely to be an indication of a material adverse impact, depending on the context.
3 Note that modelling as area sources has the effect of ‘spreading’ the noise source. However over a given assessment period (1- hour during the day and 15-minutes at night), it is consider that the front-end loader and 360 slew would have been in use across the site moving IBA as appropriate.
11055e_NVChapter_Rev1 | 22/11/2019 Page 17 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
• A difference of around +5 dB is likely to be an indication of an adverse impact, depending on the context.
• The lower the rating level is relative to the measured background sound level, the less likely it is that the specific sound source will have an adverse impact or a material adverse impact. Where the rating level does not exceed the background sound level, this is an indication of the specific sound source having a low impact, depending on the context.
3.46 Whilst there is a relationship between the level of impacts determined by the method contained within BS 4142:2014+A1:2019 and the impacts described in the NPPG, there is not a direct link. It is not appropriate to ascribe numerical rating / background level differences to LOAEL and SOAEL because this fails to consider the context of the sound, which is a key requirement of the Standard.
3.47 The impact magnitude of noise immissions at NSRs due to the operation of the proposed facility have been assessed according to the guidance and methodology contained in BS 4142:2014+A1:2019 and the NPPG and determined on the basis of professional judgement, baseline sound levels determined from surveys and the semantic scale described in Table 3.7 which provides the corresponding impact levels in the terminology of the NPPG.
3.48 Note that initial numerical rating / background level differences and the initial estimated impact are indicated. However as stated above the final magnitude of impact is dependent on the context of the sound. For example, a rating / background level difference of +6 dB may occur, indicting a medium impact, however after consideration of the context this is considered to be of low impact (e.g. due to low absolute level).

Magnitude Effect Level for Examples of Outcomes Rating / of Impact Residential Background Level NSRs (NPPG) Difference (dB) Very little change from baseline conditions. Negligible NOEL Change barely distinguishable, approximating to a >-5 'no change' situation. Note 1: The NPPG indicates that an unacceptable adverse effect (level) occurs above SOAEL; the term UAEL (Upper Adverse Effect Level) has therefore been used to describe effects at this level although it is not a term referred to in the NPSE or elsewhere in the NPPG except in the table of effects. 3.49 Note that with reference to paragraph 3.16, only effects that are moderate and above are considered to be significant in terms of the EIA Regulations. On the basis that all NSRs are of medium sensitivity, the magnitude of impact would have to be of at least medium magnitude in order to result in significant effects, i.e. such that the noise causes perceived change in the quality of life (around a rating background level difference of at least +5 dB, depending on the context).
Operational Noise Impacts: Off-Site Road Traffic Noise 3.50 The assessment of changes in road traffic noise levels on local roads as a result of the operation of the proposed development has been based on the method contained within the DMRB, which is a method designed for the assessment of new construction, improvements and maintenance of trunk roads. Therefore, the method described in DMRB is considered as informative but not definitive for the assessment of the traffic effects of the proposed development.
3.51 The calculations (based on the CRTN methodology) are based on traffic flow data provided by the transport consultant undertaking the traffic assessment and consider the difference in flows, comparing 'with' and 'without' the proposed development.
3.52 Both scenarios ‘with’ and ‘without’ the proposed facility include baseline traffic flows for the opening year and the opening year + 15 and anticipated traffic growth to 2018. In order to assess cumulative effects, a comparison has also been made between the scenario ‘with and without other committed developments for the following links:
• Link 1: Swale Way East of B2005 Grovehurst Roundabout;
• Link 2: Barge Way North of Swale Roundabout; and
• Link 3: Barge Way, East of Fleet End Roundabout.
3.53 It should be noted that Links 2 and 3 are industrial roads leading to/from Ridham Dock and no NSRs are located in close proximity to these. Only for Link 1 are NSRs located close to the road, namely residential dwellings south of Swale Way. Nevertheless, these links will be included in the following assessment for completeness.
3.54 Paragraph 3.5 of DMRB states that:
“The threshold criteria used for traffic noise assessment during the day is a permanent change in
magnitude of 1 dB LA10,18h in the short term (i.e. on opening) or a 3 dB LA10,18h change in the long
11055e_NVChapter_Rev1 | 22/11/2019 Page 19 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
term (typically 15 years after project opening). For night time noise impacts, the threshold criterion
of a 3 dB Lnight,outside noise change in the long term should also apply but only where the Lnight,outside is predicted to be greater than 55 dB for any scenario.”
3.55 Furthermore, (paragraph 3.37):
“A change in road traffic noise of 1 dB LA10,18h in the short term (e.g. when a project is opened) is the smallest that is considered perceptible. In the long term (typically 15 years after project
opening), a 3 dB LA10,18h change is considered perceptible.”
3.56 On the basis of the above, changes in road traffic sound emissions will only have the potential to cause or contribute to some harmful or otherwise unwanted effect, like annoyance or sleep
disturbance, (i.e. for the change to be an impact) if they are 3 dB LA10,18h or more in the long term.
Changes in road traffic sound emissions that are less than 3 dB LA10,18h in the long term do not give rise to an impact. Consequently, no adverse effect, significant or otherwise, can occur from such changes.
3.57 The magnitude of impact is also dependent upon the absolute level of the sound. If the levels are low, such they do not have the potential to cause or contribute to some harmful or otherwise unwanted effect, like annoyance or sleep disturbance, then the impact would be low regardless of the increase in level. Consequently, where an impact is predicted to occur, the absolute levels of road traffic sound immission are considered in terms of guidance contained within the GCN document ‘Noise Insulation Regulations’ (NIR) [18] and DMRB.
3.58 The GCN document provides guideline values for desirable internal ambient noise levels in rooms used for resting, dining and sleeping when they are unoccupied. Impacts are increasingly likely to give rise to adverse effects the greater the road traffic noise immission exceeds these guideline levels.
3.59 On this basis, the guideline internal noise levels contained within the GCN document have been converted to equivalent external noise levels on the basis that windows are sufficiently open (partially) to provide background ventilation. An external to internal sound level difference of 15 dB has been adopted based on the guidance contained within the report ‘Open/Closed Window Research – Sound Insulation through Ventilated Domestic Open Windows’ [19]. The NIR provide
LA10,18h levels above which insulation would be offered, assuming other factors are satisfied. The magnitude of impact is increased if the road traffic noise immission exceeds the threshold levels contained within the NIR.
3.60 The methodology described above has been summarised in Table 3.8 below.
11055e_NVChapter_Rev1 | 22/11/2019 Page 20 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
Table 3.8 Magnitude of Impact for Road Traffic Noise
Magnitude of Absolute Level of Traffic Noise (baseline + Change in Traffic Noise Level Impact proposed) LA10,18hr dB LA10,18hr dB ≥ 68 ≥ 5.0 High ≥ 52 ≥ 10.0 ≥ 68 3.0 to 4.9 Medium ≥ 52 & < 68 5.0 to 9.9 < 52 ≥ 10.0 ≥ 68 1.0 to 2.9 Low ≥ 52 & < 68 3.0 to 4.9 < 52 5.0 to 9.9 ≥ 52 & < 68 1.0 to 2.9 Negligible < 52 1.0 to 4.9 Any 0.1 to 0.9 No Change Any <0.1 3.61 Note that with reference to paragraph 3.16, only effects that are moderate and above are considered to be significant in terms of the EIA Regulations.
3.62 On the basis that all NSRs are of medium sensitivity, the magnitude of impact would have to be of at least medium magnitude in order to result in significant effects, i.e. a noise change of at least 3, 5 or 10 dB for where the absolute noise level is greater than 68, greater than 52, or less than
52 dB LA10,18h respectively.
Summary 3.63 With reference to Table 3.1 the significance of noise effects is a function of both the sensitivity of the NSR affected and the magnitude of the noise impact at that NSR.
3.64 In this instance all NSRs are of medium sensitivity, therefore there is a direct link between the magnitude of impact associated with the construction/operation of the IBA facility and the significance of effect.
3.65 The magnitude of noise impacts associated with the construction and operation of the IBA facility have been assessed and informed by guidance contained within the following documents:
• For onsite construction activity BS 5228-1:2009+A1:2014.
• For onsite operational activity BS 4142:2014+A1:2019 and the National Planning Practice Guidance on noise; and
• For offsite construction and operational road traffic the Design Manual for Roads and Bridges. Volume 11. Section 3 - Part 7: Noise and Vibration.

4 Limitations of the Assessment
4.1 In all assessments, it is good practice to consider uncertainty, which can arise from a number of different aspects of an assessment. There is a degree of uncertainty associated with: the instrumentation itself; the use of instrumentation, i.e. the measurements; the source terms used; the sound propagation model; and the subjective response of residents to the sound sources.
4.2 With regard to subjective response, the acoustics standards and guidance adopted for the assessments within this chapter are based on the subjective response of the majority of the population. This is considered to be the best that can be achieved in a population of varying subjective responses, which are dependent upon a wide range of factors.
4.3 On the basis of the above, whilst the magnitude of uncertainty has not been quantitatively defined, measures have been taken to minimise this aspect in accordance with best practice.
Baseline Characterisation
4.4 Uncertainty due to instrumentation error has been significantly reduced with the introduction of modern instrumentation and is reduced further by ensuring that all instrumentation is calibrated before and after each measurement period and is within accepted calibration intervals.
4.5 Uncertainty in the baseline data has been reduced significantly by carrying out baseline sound monitoring over a period of seven days, allowing analysis of how representative the baseline data are given the naturally varying sound level at NSRs within the vicinity of the site.
Operation of the Proposed Facility
4.6 Operational sound emissions have been determined from acoustic data provided by the technology providers and from data within the RPS Source Term Library of similar plant and facilities. Therefore, these data are estimates of realistically achievable sound levels although the final plant servicing the facility may vary from that which has been modelled. However, any plant included in the facility would need to comply with the Environmental Permitting Regulations (EPR), and therefore demonstrate that the techniques used represent Best Available Techniques (BAT), which would include minimising noise immissions at NSRs, among other requirements.
4.7 Sound immissions at NSRs have been calculated using the prediction methodology in ISO 9613- 2:1996. For source heights up to 30 metres and prediction distances between 100 and 1,000 metres, ISO 9613-2:1996 claims accuracy of +/-3 dB. ISO 9613-2 is widely used for the prediction of industrial noise and is referred to in BS 4142:2014+A1:2019.
4.8 On the basis of the above, it is considered that limitations to the assessment have been minimised and that the results provide a robust estimate of the likely noise effects of the development.
11055e_NVChapter_Rev1 | 22/11/2019 Page 22 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
Road Traffic Noise Assessment
4.9 The assessment of noise from road traffic is limited to the traffic data provided. Further details of the assumptions used in deriving the traffic data are provided in the transport assessment.
4.10 The CRTN prediction method is based on free-flowing traffic on main roads and typical noise levels from cars and HGVs. Vehicles have changed since the time that the guidance was drafted and typically it is expected that HGVs in particular will be quieter. Therefore, the predictions of absolute noise levels produced by road traffic are potentially higher than road traffic noise levels will be in practice. Predictions of changes in noise levels are likely to be robust.

5 Baseline Conditions
Existing Baseline Conditions
5.1 Surveyed baseline sound level data was logged in 100 ms periods. This has been post-processed to provide 15-minute sound level data. The results of the long-term baseline sound level survey are presented in Table 5.1 below. Further details are provided in Appendix B. Note that the data presented Table 5.1 excludes two 24-hour periods of data due to unrepresentative weather conditions.
Table 5.1 Long Term 15-minute Baseline Sound Level Data
Daytime (07:00 to 23:00 hours) Night-time (23:00 to 07:00 hours) Value Residual Sound Background Sound Residual Sound Background Sound Level (dB LAeq,T) Level (dB LA90,T) Level (dB LAeq,T) Level (dB LA90,T) Minimum 37 34 32 28 25th 44 41 37 33 Percentile Median 47 43 40 36 Average 47 43 40 36 75th 49 45 43 39 Percentile Maximum 65 49 50 47 Note that 25th percentile sound levels were all 1 dB higher when considering the entire seven-day period ‘as a whole’, including periods when measured sound levels were affected by wind/rain. 5.2 It should be noted that the baseline acoustic environment at the location of the nearest residential NSRs was noted as being typical of a residential environment forming part of a small town/village. Background sound levels, particularly during the night-time period, would be largely affected by distant road traffic movements on the A249, located approximate 480 m to the east.
5.3 The results of the short-term baseline sound level survey undertaken within the nature reserve are presented in Table 5.2 below, also shown are the corresponding sound levels measured at the long-term location for the same period. Further details are provided in Appendix B. Note that data logged during two HGV pass-bys during the short-term survey has been removed from the levels presented in Table 5.2.

5.4 The baseline acoustic environment on the area of the Ramsar site was noted as being affected by continuous road traffic on the A429 road, occasional aircraft overhead (during which time sound levels increased by around 15 dB, from 40 to 55 dBA) and two gunshots, or other similar impulsive noise sources (potentially from Kingsferry Gun Club).
5.5 In addition, two large HGV vehicles passed close by the survey location during the measurement on the minor road that passes through the Nature Reserve. Note that data logged during these two pass-bys have been removed from the data presented in Table 5.2 above.
Representative Baseline Levels 5.6 BS 4142:2014+A1:2019 requires that the background sound levels adopted for the assessment are representative of the period being assessed. The Standard recommends that the background sound level should be derived from continuous measurements of normally not less than 15 - minute intervals, which can be contiguous or disaggregated (paragraph 8.13 of BS 4142:2014+A1:2019).
5.7 However, the Standard states that there is no ‘single’ background sound level that can be derived from such measurements. It is particularly difficult to determine what is ‘representative’ of the night- time period because it can be subject to a wide variation in background sound level between the beginning and end of the night period, and the quieter middle part of the night period. The accompanying note states that “a representative level should account for the range of background sounds levels and should not automatically be assumed to be either the minimum or modal value”.
5.8 In this instance the 25th percentile from the long term has been used to characterise the baseline sound environment. This is not the lowest sound level encountered but is lower than that obtained using the average. It therefore represents somewhere in the range of lower sound pressure levels that are likely to be encountered and provides a precautionary assessment. Use of the 25th percentile ensures that any periods when higher wind speeds could have affected the measured baseline sound levels do not unduly affect the analysis.
5.9 Similarly, representative baseline residual levels have been based on the 25th percentile levels.
5.10 On the basis of the above, representative baseline background sound levels for the nearest
residential NSRs in Iwade are 41 and 33 dB LA90,T for the daytime and night-time periods
respectively. Representative baseline residual sound levels are 44 and 37 dB LAeq,T for the daytime and night-time periods respectively.
5.11 With reference to Table 5.2 can be seen that background and ambient sound levels measured within the Ramsar site during the short-term survey are 4 and 2 dB lower than those logged at the long-term location respectively.
5.12 Whilst the two survey locations are relatively distant, it is considered that the primary noise sources affecting the acoustic environment at both locations are the same, i.e. road traffic movements on
11055e_NVChapter_Rev1 | 22/11/2019 Page 25 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
the A429 and overhead aircraft; on this basis, the level difference would be relatively constant across the daytime and night-time periods.
5.13 On the basis of the above, representative baseline residual sound levels for the Ramsar site are
42 and 35 dB LAeq,T for the daytime and night-time periods respectively (i.e. 2 dB lower than the at the long term survey location).
5.14 Representative baseline sound levels are summarised in Table 5.3 below.
Table 5.3 Representative Baseline Sound Levels
Daytime (07:00 to 23:00 hours) Night-time (23:00 to 07:00 hours) NSR Residual Sound Background Sound Residual Sound Background Sound Level (dB LAeq,T) Level (dB LA90,T) Level (dB LAeq,T) Level (dB LA90,T) Residential 44 41 37 33 Dwellings Ramsar/SPA 42 37 35 29 SSSI Future Baseline Conditions
5.15 At both NSR locations considered in this assessment, the baseline acoustic environment is primarily affected by transport, i.e. road traffic movements and aircraft.
5.16 On the basis that road and air traffic movements will not change significantly in the future, it is considered that the acoustic environment will also not change significantly in the future.

6 Incorporated Enhancement and Mitigation
6.1 The mitigation measures proposed as part of the IBA facility construction and design in relation to noise and vibration are described below.
Construction Phase
6.2 Construction works would follow Best Practicable Means (BPM) outlined in Section 72 of the Control of Pollution Act 1974 (as amended) to minimise noise and vibration effects. Such details will be required by the Construction Environmental Management Plan (CEMP) to be submitted to and agreed in writing with KCC prior to commencement of construction activities and following the appointment of a contractor.
Operational Phase
6.3 In order to comply with Environmental Permitting Regulations (EPR), the plant would be designed to present Best Available Techniques (BAT), which will include limiting noise generation by the plant where practicable.
6.4 HGVs would follow the approved access routes to and from site.

7 Assessment of Construction Effects
Onsite Construction Activity 7.1 Noise levels associated with the construction of the facility at the nearest residential NSRs in Iwade
are 26 dB LAeq,T. Noise contour plots for the construction period are provided in Figure 3.
7.2 With reference to Table 3.4, construction noise levels of 26 dB LAeq,T are of ‘negligible’ magnitude; however it is considered that, given the low noise level and baseline residual/background levels, that construction activity would be unlikely to be noticeable and, on this basis, an impact magnitude of ‘no change’ may be more appropriate. When combined with the medium sensitivity of receptor, the significance of effect is none.
7.3 On the basis that residential NSRs are of ‘medium’ sensitivity and construction noise impacts are ‘negligible’, then with reference to Table 7.1 resultant construction noise effects are of ‘negligible’ significance, which is not considered significant in EIA terms.
7.4 As negligible effects are predicated no specific mitigation measures would be required. However, it would be recommended that construction works follow the principle of ‘Best Practicable Means’ (BPM) as outlined in Section 72 of the Control of Pollution Act 1974 to minimise the risk of noise and effects as far as practicable.
7.5 Note that predicted construction noise levels at the Ramsar/SPA/SSSI are 39 dB LAeq,T. As such future ambient sound levels at the Ramsar/SPA/SSSI during the construction phase would be
4 44 dB LAeq,T for the daytime period , a 2 dB increase (no construction activity is planned during the night-time period). The significance of this noise change is covered in the Ecology and Nature Conservation Chapter.
Off-Site Road Construction Traffic 7.6 Based on information provided by the civils contractor, up to 25 HGV construction related vehicles will attend the site per day. These construction HGVs have been added to baseline flows (50 added to baseline flows to take into account two-way movements) to determine total road traffic movements during the construction phase.
7.7 The magnitude of impacts during the daytime is determined from the absolute traffic noise levels and predicted change in road traffic noise levels comparing the flows for the baseline and with additional construction related traffic using the methodology described in paragraphs 3.50 to 3.62 of this chapter.
4 Baseline ambient level of 42.5 dB LAeq,T plus construction level of 39.0 dB LAeq,T.
11055e_NVChapter_Rev1 | 22/11/2019 Page 28 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
7.8 The predicted road traffic noise levels and magnitude of impacts are summarised in Table 7.1 below.
Table 7.1 Construction Traffic Assessment
Road Traffic Sound Level, Change Magnitude Link LA10,18h (dB) (dB) of Impact Baseline with Development Swale Way East of B2005 71 71 0 No Change Grovehurst Roundabout Barge Way North of Swale 65 65 0 No Change Roundabout Barge Way, East of Fleet End 64 64 0 No Change Roundabout 7.9 From Table 7.1 the change in road traffic sound level is 0 dB (0.0 dB to one decimal place), therefore there is no impact associated with construction road traffic movements.
7.10 On the basis that residential NSRs are of ‘medium’ sensitivity and construction road traffic noise impacts are of ‘no impact’ then with reference to Table 3.1 there are no significant construction road noise effects.
11055e_NVChapter_Rev1 | 22/11/2019 Page 29 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
8 Assessment of Operational Effects
Residential NSRs
Onsite Operational Activity 8.1 The predicted specific sound levels from the operational facility at residential NSRs and the results of the numerical BS 4142:2014+A1:2019 assessment are provided in Table 8.1 below. The change in the ambient sound levels at NSRs has also been determined by adding the level of residual and specific sound levels.
8.2 Operational noise contour plots for the daytime and night-time periods are provided in Figures 4 and 5.
8.3 With reference to BS 4142:2014+A1:2019, a character correction can be applied to the specific sound level depending on the acoustic characteristics of the sound. In this instance, sound emissions from the operational facility, whilst potentially tonal, impulsive or readily distinctive at the site, would very likely not be noticeable at residential NSRs 1.5 km distant from the site (predicted
specific sound level are 23 dB LAeq,Tr). On this basis, it is not considered appropriate to apply a character correction to predicted specific sound levels and the rating sound level is equal to the specific sound level.
Table 8.1 Numerical BS 4142:2014+A1:2019 Assessment
Rating Rating Change Background Residual Specific Ambient Level, Background in Location Level Level dB Level, Sound Level dB Level Ambient dB LA90 LAeq,T dB LAeq,T dB LAeq,T LAr,Tr Difference Level dB
Daytime (07:00 to 23:00 hours)
Iwade 41 44 21 21 -20 44 0
Night-time (23:00 to 07:00 hours)
Iwade 33 37 21 21 -12 37 0
8.4 With regards to the rating/background level difference, BS 4142:2014+A1:2019 states:
• A difference of around +10 dB or more is likely to be an indication of a significant adverse impact, depending on the context;
• A difference of around +5 dB is likely to be an indication of an adverse impact, depending on the context; and
11055e_NVChapter_Rev1 | 22/11/2019 Page 30 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
• The lower the rating level is relative to the measured background sound level, the less likely it is a very low risk that the specific sound source will have an adverse impact at the nearest residential NSRs, depending on the context.
8.5 As rating sound levels are 20 and 12 dB below the representative background sound level during the daytime and night-time periods, respectively it is considered that adverse impact is unlikely.
8.6 Consideration of the context further reduces the likelihood for adverse impact. This is on the basis
that the rating sound level of 21 dB LAr,Tr is considered to very low and in addition there would be no change in the ambient sound level (the rating sound level is 16 dB below night-time ambient level). On this basis it is considered likely that the facility would not be audible at residential NSRs.
8.7 On the basis of the above, and with reference to Table 3.7 it is considered that the magnitude of impact at the nearest residential NSRs would be ‘negligible’ i.e. very little change from baseline conditions, and any change barely distinguishable, approximating to a 'no change' situation.
8.8 On the basis that residential NSRs are of ‘medium’ sensitivity and operational noise impacts are of ‘negligible’ magnitude then, with reference to Table 3.1, resultant operational noise effects are of ‘negligible’ significance, which is not considered significant in EIA terms.
8.9 Note that predicted operational noise levels at the Ramsar/SPA/SSSI are 35 and 34 dB LAeq,T for the daytime and night-time periods respectively. As such future ambient sound levels during
operation of the IBA Facility at the Ramsar/SPA/SSSI would be 43 and 38 dB LAeq,T for the daytime and night-time periods respectively5. The significance of this noise change is covered in the Ecology and Nature Conservation Chapter.
8.10 On the basis that operational noise effects are of ‘negligible’ significance no mitigation measures would be required.
Off-Site Road Operational Traffic 8.11 The magnitude of impacts during the daytime is determined from the absolute traffic noise levels and predicted change in road traffic noise levels at residential NSRs comparing the flows for the year opening year of the facility ‘with’ and ‘without’ the development using the methodology described in Section 8.3 of this chapter. The predicted road traffic noise levels and magnitude of impacts are summarised in Table 8.2 below.
8.12 It should be noted that, whilst use of the facility will result in up to 205 HGV movements per day, the facility is only expected to generate an additional 39 net HGV movements above the pre-existing use of the site as a car shredding facility and the already approved IBA movements associated with the Kemsley SEP facility.
5 43.1 and 37.6 dB LAeq,T for the daytime and night-time periods respectively, 0.7 and 2.6 dB increase respectively.

8.14 On the basis that residential NSRs are of ‘medium’ sensitivity and construction road traffic noise impacts are of ‘no impact’ then, with reference to Table 3.1 there are no significant construction road noise effects.

9 Assessment of Decommissioning Effects
9.1 The activities associated with the future decommissioning of the facility would be similar to those for construction. It is therefore unlikely that this activity would lead to any greater disruption and it is possible that noise and vibration levels at NSRs from decommissioning would be quieter than for the construction phase due to improvements in plant technology in future years.
11055e_NVChapter_Rev1 | 22/11/2019 Page 33 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
10 Assessment of Cumulative Effects
10.1 Traffic data have been provided by the transport consultants undertaking the transport assessment for the project that include additional road traffic movements above the baseline situation associated with the operation of the IBA facility and other additional development in the area.
10.2 On this basis the predicted road traffic noise levels and magnitude of impacts are summarised in Table 10.1 below.
Table 10.1 Cumulative Traffic Assessment
Road Traffic Sound Level, Change Magnitude Link LA10,18h (dB) (dB) of Impact Baseline with Development Swale Way East of B2005 Negligible Grovehurst Roundabout 71.5 71.7 0.2 Barge Way North of Swale Negligible Roundabout 64.6 65.1 0.5 Barge Way, East of Fleet End Negligible Roundabout 63.7 64.7 0.9
10.3 With reference to Table 10.1 above, the maximum change in road traffic sound level is 0.9 dB to one decimal place. With reference to Table 3.1 noise changes of less than 3 dB in the long-term are of negligible adverse impact, regardless of the overall noise level.
10.4 On the basis that residential NSRs are of ‘medium’ sensitivity and cumulative road traffic noise impacts are of ‘negligible’ impact then with reference to Table 3.7 cumulative road traffic noise effects are of ‘negligible’ significance, which is not considered significant in EIA terms.
10.5 With regards to cumulative noise effects associated with onsite operational activities, i.e. the processing of IBA, it is considered that cumulative effects would not significant. This is on the basis that any other relevant development with the potential to affect NSRs would be designed and operated such that this development itself does not result in significant noise effects. In addition, as outlined in paragraph 8.10, operational noise effects associated with facility are negligible and
further more noise levels of 21 dB LAeq,T at the nearest NSRs are considered very low.
10.6 On the basis of the above, it is considered that cumulative noise levels would very likely not increase to an extent that previously insignificant noise effects would then be deemed as significant with the introduction of the operational IBA Facility.
11055e_NVChapter_Rev1 | 22/11/2019 Page 34 www.rpsgroup.com ENVIRONMENTAL STATEMENT – NOISE & VIBRATION. DEVELOPMENT OF AN IBA RECYCLING FACILITY, RIDHAM DOCK
11 Summary and Conclusions
11.1 A detailed noise and vibration assessment considering the potential effects of emissions generated during the construction and operation of the IBA facility has been undertaken.
11.2 The plant and equipment associated with the construction and operation of the facility would not produce high levels of vibration. In addition, vibration levels drop off rapidly with distance. Therefore, vibration effects from the construction and operation of the proposed facility have been scoped out of the assessment.
11.3 Based on the results of long and short-term baseline surveys, detailed 3D noise modelling and assessment construction and operational noise effects at the nearest residential noise and vibration sensitive receptors would be of negligible significance.
11.4 Noise effects at NSRs associated with the operational of the proposed IBA facility and other cumulative development would also be of negligible significance.
11.5 Furthermore, construction and operation of the proposed IBA facility would not adversely affect use other aspects of the Ridham Dock site.
11.6 On the basis of the above, construction and operation of the proposed IBA facility would not result in significant/unacceptable adverse impacts/effects. As such the proposals would be compliant with National and Local Planning policy.
11.7 Table 11.1 summarises the significance of effects for the construction and the operational phases for the project.
