1 Introduction

PDE Consulting Limited is preparing to submit a planning application and associated

information on behalf of FM Conway Limited to erect an asphalt plant, concrete batching

plant, gully waste plant and ancillary development and access on land off North Quay

Road, Newhaven.

It is proposed by FM Conway Limited that they have the ability to operate the asphalt plant

at any time for the manufacture and distribution of asphalt, along with the importation of

road planings and returned loads of asphalt and the discharge from tankers at the gully

waste processing area. It is proposed to restrict the other plant operations and material

importation to the hours of 7 am to 7 pm Monday to Friday and 7 am to 1 pm on Saturdays.

This report addresses the environmental noise implications of the proposal by setting out

the findings of sample and longer term noise measurements at the nearest properties to

the site; discussing the existing noise climate, and presenting the calculated noise levels

arising from the proposed operations. An assessment of the calculated noise levels has

been carried out in accordance with British Standard 4142:2014.

To aid comprehension, a glossary of acoustic terms is presented in Appendix A.

2 Assessment Methodology

The various relevant noise guidance documents used in this assessment are detailed

below.

2.1 Local Planning Authority

The proposed development site falls under the jurisdiction of East Sussex County Council

(ESCC). In October and November 2016 WBM contacted Andrew Arnold (Environmental

Health, ESCC) and discussed the proposal and points to be considered with the noise

assessment. Mr Arnold directed WBM to the document “Planning Noise Advice Document:

Sussex” (July 2015) and suggested looking at the noise assessment prepared for the

Veolia Energy from Waste Facility. Both documents were provided to WBM by ESCC.

In Section 2 of Planning Noise Advice Document: Sussex, the following extract sets out the

approach that a noise assessment should follow, with regard to Industrial and Commercial

Noise Sources.

of 57

The starting point for designing any industrial/ commercial development should be to

minimise noise “as far as reasonably practicable”. The rating level of the plant/process,

when measured in accordance with BS4142:2014, should, where practicable, be no greater

than the existing background levels when measured in accordance with BS4142:2014.

There may be instances, for specific sites, where a rating level below background is

deemed appropriate. This can be determined through prior discussion with the Local

Planning Authority or Local Environmental Health Department. For example, a rating level

of 10 dBA below background may be required in certain instances if there are specific

concerns such as the potential for noise creep. It is considered that meeting these criteria

would avoid adverse noise impacts, in the interests of ensuring a good standard of amenity

and protecting human health. Where these criteria are not attainable, the noise report

should explain why, and how best practicable means will be implemented to control noise

in order to satisfy the LPA that the development is acceptable.

Pre-application advice was requested from East Sussex County Council (ESCC) by PDE

Consulting Limited on 21 November 2016 and a response was received from Jeremy

Patterson (Principal Planning Officer, ESCC) on 21 December 2016. With regard to noise,

the following information was provided.

“Noise/Air Quality

Relevant reports would need to state clearly which standards are being worked to and why.

For noise, for example, it should be an absolute and a relative standard.

An explanation would be required as to the difference, if any, regarding points (iv) and (v)

at paragraph 4.5 of the Scoping Report.”

For information, paragraph 4.5 in the Scoping Report states the following;

“Noise/Air Quality

4.5 The possible effects on noise/air quality from the Development Area may include:

i. Identification of sensitive receptors

ii. Assessment of impacts upon them

iii. Conflicts with local, regional and national policies

iv. Increased noise and windblown dust

v. Longer exposure to noise and dust

vi. Impacts on ecology”

2.2 National Planning Policy Framework (NPPF) Technical Guidance

The Department for Communities and Local Government issued the National Planning

Policy Framework (NPPF), dated March 2012. The NPPF was published on 27 March 2012

with immediate effect.

The NPPF revokes and replaces a number of Planning Policy Statements (PPS), Planning

Policy Guidance (PPG) and other guidance documents, including the following:

Planning Policy Guidance 24: Planning and Noise (published October 1994) and Minerals

Policy Statement 2: Controlling and Mitigating the Environmental Effects of Minerals

Extraction in England. This includes Annex 2: Noise (published May 2005).

The following text at paragraphs 109 and 123 in the NPPF are under the heading

“Conserving and enhancing the natural environment”.

Paragraph 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

noise pollution.”

Paragraph 123 “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 (Footnote:

subject to the provisions of the Environmental Protection Act 1990 and other relevant law); 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.”

of 57

2.3 British Standard 4142

British Standard (BS) 4142:2014 "Methods for rating and assessing industrial and

commercial sound" describes methods for assessing the likely effects of sound on

premises used for residential purposes. It includes the assessment of sound from industrial

and manufacturing processes, M&E plant and equipment, loading and unloading of goods

and materials, and mobile plant/vehicles on the site. It can be used to assess sound from

proposed, new, modified or additional industrial/commercial sources, at existing or new

premises used for residential purposes.

The standard describes methods to measure and determine ambient, background and

residual sound levels, and the rating levels of industrial/commercial sound. This latest

edition of BS 4142 also requires consideration of the level of uncertainty in the data and

associated calculations.

BS 4142 is not intended to be used for the derivation or assessment of internal sound

levels, or for the assessment of non-industrial/commercial sources such as recreational

activities, motorsport, music and entertainment, shooting grounds, construction and

demolition, domestic animals, people, and public address systems for speech.

Ambient sound is defined in BS 4142 as "totally encompassing sound in a given situation at

a given time, usually composed of sound from many sources near and far". It comprises

the residual sound and the specific sound when present.

Residual sound is defined in BS 4142 as "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". The background sound level is the LA90,T of the residual

sound level, and is the underlying level of sound. Measurements of background sound level

should be undertaken at the assessment location where possible or at a comparable

location. The measurement time interval should be sufficient to obtain a representative

value (normally not less than 15 minutes) and the monitoring duration should reflect the

range of background sound levels across the assessment period. The background sound

level used for the assessment should be representative of the period being assessed.

The specific sound level is the LAeq,Tr of the sound source being assessed over the

reference time interval, Tr. BS 4142 advises that Tr should be 1 hour during the day (07:00

– 23:00) and 15 minutes at night (23:00 – 07:00).

of 57

The rating level is the specific sound level plus any adjustment for the characteristics of the

sound (tone, impulse, intermittent or other acoustic feature). The standard describes

subjective and objective methods to establish the appropriate adjustment. The adjustments

for the different features and assessment methods are summarised below:

Acoustic Feature

Adjustment for Acoustic Feature

Subjective Methods Objective Methods

Tonality +2 dB if just perceptible

+4 dB if clearly perceptible

+6 dB if highly perceptible

Third Octave Analysis Narrow Band Analysis

+6 dB if tones identified Sliding scale of 0 to +6 dB depending on audibility of tone

Impulsivity +3 dB if just perceptible



Sliding scale of 0 to +9 dB depending on prominence of impulsive sound

Intermittency + 3 dB if intermittency is readily distinctive

n/a

Other + 3 dB if neither tonal nor impulsive, but otherwise readily distinctive

n/a

Where tonal and impulsive characters are present in the specific sound within the same

reference period then these two corrections can both be taken into account. If one feature

is dominant, it might be appropriate to apply a single correction. The rating level is equal to

the specific sound level if there are no features present.

The level of impact is assessed by comparing the rating level of the specific sound source

with the background sound level. The greater the difference, the greater the magnitude of

the impact depending on the context. Other factors that may require consideration include

the absolute level of sound, the character and level of the residual sound compared to the

specific sound, and the sensitivity of the receptor and scope for mitigation.

When the rating level is above the background sound level, a difference between these

levels of around +5 dB is likely to indicate an adverse impact and a difference of around

+10 dB or more is likely to indicate a significant adverse impact, depending on the context.

The lower the rating level with respect to the background sound level, the less likely it is

that the specific sound source will have an 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.

2.4 British Standard 8233

British Standard (BS) 8233: 2014 “Guidance on sound insulation and noise reduction for

buildings” gives recommendations for the control of noise in and around buildings, and

suggests indoor ambient noise levels for dwellings from noise sources without a specific

character (“anonymous noise”).

For dwellings, the main considerations are the acoustic effects on sleep in bedrooms, and

resting, listening and communicating in other rooms.

The suggested levels in dwellings due to steady external noise, such as road traffic,

mechanical services or continuously running plant, are presented below based on Table 4

of BS 8233: 2014:

Activity Location Indoor ambient noise levels

Daytime 07:00 to 23:00 hours

Night-time 23:00 to 07:00 hours

Resting Living room 35 dB LAeq,16hour -

Dining Dining room/area 40 dB LAeq,16hour -

Sleeping / daytime resting Bedroom 35 dB LAeq,16hour 30 dB LAeq,8hour

BS 8233: 2014 notes the following:

The suggested levels are based on existing guidelines issued by the World Health

Organisation and assume normal diurnal fluctuations in external noise. In cases

where local conditions do not follow a typical diurnal pattern, an appropriate

alternative time period, e.g. 1 hour, may be used but the level should be selected to

ensure consistency with the recommended values tabulated above.

Regular individual events, e.g. aircraft or trains, can cause sleep disturbance.

Guideline values may be required in terms of a single event level (SEL) or

maximum value (LAmax,f) depending on the character and number of events per

night.

If relying on closed windows to meet the guideline values, there needs to be an

appropriate, alternative means of ventilation that does not compromise the façade

insulation or the resulting internal noise level.

of 57

Where development is considered necessary or desirable, the internal levels

tabulated above may be relaxed by up to 5 dB and reasonable internal conditions

still be achieved.

As well as indoor ambient noise limits, BS 8233 also provides design criteria for noise

outside dwellings. For traditional external areas that are used as amenity spaces (e.g.

gardens) it is desirable that external noise does not exceed 50 dB LAeq,T with an upper

guideline value of 55 dB LAeq,T, which would be acceptable in noisier environments.

However, in higher noise areas, such as city centres or adjacent to the strategic transport

network, a compromise between elevated noise levels and other factors might be

warranted. BS 8233: 2014 advises that in such situations, development should be designed

to achieve the lowest practicable levels in these external amenity spaces, but should not be

prohibited.

For residential building where normal external amenity space might be limited or not

available, the specification of noise limits in areas such as small balconies (for example

used for drying washing or growing pot plants) is not necessarily appropriate. However, the

general guidance on noise in amenity space is still appropriate for larger balconies, roof

gardens and terraces, which are intended to be used for relaxation. In high-noise areas,

consideration should be given to protecting these areas by screening or building design to

achieve the lowest practicable levels. BS 8233: 2014 states “Achieving levels of 55 dB LAeq,T

or less might not be possible at the outer edge of these areas, but should be achievable in some

areas of the space.”

2.5 World Health Organisation

Guidelines for Community Noise 1999

The World Health Organisation (WHO) “Guidelines for Community Noise” 1999 provides

guidance on community noise based on knowledge of the health impacts of community

noise and also provides guidance on the protection of people from the harmful effects of

noise in non-industrial environments. Some of the relevant guideline values according to

specific environments and critical health effects are tabulated below.

of 57

Specific environment

Critical health effect LAeq (dB)

Time base (hours)

LAmax,fast (dB)

Outdoor living area

Serious annoyance, daytime and evening

55 16 -

Outdoor living area

Moderate annoyance, daytime and evening

50 16 -

Dwellings, indoors

Speech intelligibility and moderate annoyance, daytime and evening

35 16 -

Inside bedrooms Sleep disturbance, night-time 30 8 45

Outside bedrooms

Sleep disturbance, window open (outdoor values)

45 8 60

According to the WHO guidelines, the time base for LAeq,T values is 16 hours for daytime

(including evening) and 8 hours for night-time.

The effects of noise in dwellings are usually sleep disturbance, annoyance and speech

interference. For bedrooms the critical effect is sleep disturbance. The WHO indoor

guideline values for bedrooms are 30 dB LAeq,T for continuous noise. If the noise is not

continuous, maximum noise levels should be used to indicate the probability of noise-

induced awakenings with 45 dB LAmax,f as the relevant criterion. The WHO guidelines state

that “For a good sleep, it is believed that indoor sound pressure levels should not exceed

approximately 45 dB LAmax more than 10-15 times per night…”

At night-time, external noise levels outside the façades of bedrooms should not exceed 45

dB LAeq,T and 60 dB LAmax,f and so that people may sleep with bedroom windows open,

assuming a noise reduction of 15 dB from outside to inside with the window open.

To protect the majority of people from being seriously annoyed during the daytime, the

outside noise level from steady, continuous noise should not exceed 55 dB LAeq,T on

balconies, terraces and in outdoor living rooms. To protect the majority of people from

being moderately annoyed during the daytime, the outside noise level should not exceed

50 dB LAeq,T.

It is important to note that these are health based guidelines rather than levels set out in

current Government legislation.

of 57

Night Noise Guidelines for Europe 2009

The World Health Organization “Night Noise Guidelines for Europe” 2009 document

provides guidelines that are neither standards nor legally binding criteria. The guidelines

may be considered as an extension to, as well as an update of, the previous WHO

“Guidelines for Community Noise” 1999.

This document proposes that an Lnight,outside of 40 dB should be the target of the night noise

guideline (NNG) to protect the public. The Lnight,outside indicator is defined in Environmental

Noise Directive 2002/49/EC and is the year average at the most exposed facade. It is the

long-term A-weighted average sound level (LAeq) determined over all the night periods of a

year, where night is eight hours in duration (usually 23.00 to 07.00 hours) and a year is a

relevant year as regard the emission of sound and an average year for meteorological

conditions. The Lnight,outside is determined at a receiver height of 4 metres above local ground

and is taken to be a free field level even though it would be assessed near the most

affected façade of a dwelling.

The Night Noise Guidelines also reports that effects on sleep quality can occur at a

threshold levels of 42 dB LAmax,inside (internal level) although biological effects such as

changing sleep structure can occur at lower noise levels.

3 Site Description

The proposed site is Plots 6 and 7 off North Quay Road, Newhaven, which is in a large

area of industrial and commercial premises known as North Quay Industrial Estate.

The site is bounded to the east by North Quay Road and to the west by the River Ouse.

Directly to the north and south of the site are metal recycling / scrap metal companies.

To the east of North Quay Road is an existing asphalt plant operated by Tarmac.

To the west of the site and the River Ouse is Denton Island which is an area of commercial

and business units.

Further to the north-northwest of the site is the Veolia Energy Recovery Facility.

of 57

The closest dwellings are approximately 260 metres to the site to the south and southwest

of the site on North Way, including Bridge Court which is a 3 storey block of flats.

Approximately 410 metres to the west of the site there are dwellings on Elphick Road that

are 2 storey houses and are on a ground height of 10 metres AOD. At the northern end of

Elphick Road / Robinson Road is Lee Court which is a 4 storey block of flats on a ground

height of 5 metres AOD.

To the northeast of the site are dwellings that are separated from the site by the majority of

North Quay Industrial Estate. These properties to the northeast of Avis Road are at least

600 metres from the site. The ground height to the northeast of Avis Road increases from

an initial ground height of 4 metres AOD, with the ground height of properties on Beresford

Road further to the east at 20 metres AOD.

The location of the site and the surrounding residential properties are shown on a plan in

Appendix B.

4 Baseline Noise Surveys

Survey work was undertaken with both short-term attended sample measurements during

daytime and night-time periods and longer-term installed meters at two locations. Attended

sample measurements were carried out at the following positions;

Robinson Road (rear of properties on Elphick Road)

North Way / Bridge Court

Avis Road

Beresford Road

Sound level meters were also installed at the following locations;

71 Elphick Road

65 Beresford Road

Details of the attended and install survey positions are shown on a marked plan and

described in Appendix B

An initial site visit was undertaken on Wednesday 23 November 2016 to obtain sample

measurements near to the selected dwellings, as detailed above. Measurements were

taken during the night-time and the subsequent daytime.

of 57

Further measurements of the existing noise climate were made during the daytime on

Tuesday 10 and during the night-time on Tuesday 10 / Wednesday 11 January 2017.

Data logging sound level meters were installed at the locations detailed above on Tuesday

10 January 2017 and collected on Thursday 26 January 2017. Due to battery failure the

noise measurements at 71 Elphick Road stopped at 11 am on Monday 23 January 2017

and at 65 Beresford Road at 8 am on Wednesday 25 January 2017. The installed meters

measured the noise climate for at least 12 days, including 2 weekend periods.

The survey, instrumentation and calibration details are included as Appendix D and the

attended noise survey results are set out in Appendix E.

A summary of the survey results for the daytime and night-time noise levels is presented

below. For the daytime samples all the measurements taken at each position are shown

and for night-time the average of the sample measurements is shown.

Detailed results from the data logging sound level meters installed at the positions

described are presented in Appendix E. Following the approach used by the acoustic

consultants for the Veolia Energy from Waste site, the 25th percentile has been calculated

from all the measurement results. The 25th percentile LA90,1 hour values for the daytime

(07:00 to 23:00) and night-time (23:00 to 07:00) periods are presented below.

Based on the background sound level data collected, the following representative

background sound levels for each position have been adopted in the noise assessment.

For Elphick Road and Beresford Road the data from the installs has been used and for

North Way / Bridge Court and Avis Road the sample measurements have been used.

Lee Court, Elphick Road 39 33

In addition to the selected survey positions, an additional position has been used for

calculation purposes at Lee Court on the corner of Elphick Road and Robinson Road. The

Background Noise Levels for this location have been assumed to be the same as for

Elphick Road.

5 Calculated Site Noise Levels

5.1 Calculated Site Noise Levels

The Equivalent Continuous Noise Level, LAeq, T, is the preferred unit for assessing noise

sources. It is the value of a continuous level that would have equivalent energy to the

continuously varying noise over the specified period "T". This unit is recommended

internationally for the description of environmental noise and is in general use.

The noise levels likely to arise at dwellings depend on the method of working and the

sound power levels of the plant chosen to work a site as much as on the distance to the

properties and the effects of intervening ground. Proper allowance can be made for these

variables to calculate site noise levels.

5.2 Noise Calculation Methodology

The Planning Practice Guidance does not provide details of noise calculation methods to

be used. In the absence of detailed guidance, the calculations in this report are based on

the methods contained in BS5228-1: 2009 “Code of practice for noise and vibration control

on construction and open sites – Part 1: Noise” as amended BS5228-1:2009+A1:2014.

of 57

For the purposes of examining a “reasonable worst case”, the proposed plant items have

been assumed to operate simultaneously, with on-time percentages in one hour for

daytime or 15 minutes for night-time as shown in the calculation sheet.

Further details of the calculation methods are set out in Appendix F to this report. A

summary site noise calculation sheet for one of the five locations considered is included in

Appendix F for inspection.

5.3 Site Activities

The main operations that are proposed to occur at the site are as follows;

Importation of Aggregates

Asphalt Plant

Concrete Batching Plant

Gully Waste Processing

It is proposed by FM Conway that the following elements of the development can have

unrestricted hours of working

The manufacture and distribution of asphalt

The importation of road planings and returned loads

The use of the gully waste area and associated HGV movements

Other elements of the proposed development, most significantly in noise terms the

concrete batching plant and the delivery of materials, are proposed to be restricted to

between the hours of 7 am to 7 pm Monday to Friday and 7 am to 1 pm Saturdays.

Both the asphalt plant and the concrete batching plant will be fed with sand and aggregate

using loading shovels that will tip material into hoppers. Lorries will arrive at the site and be

loaded as required. Cement will also be delivered to the site on a regular basis.

In order to assess the noise levels for the proposed site operations, the contribution from

each significant specific noise source has been evaluated separately and then combined to

give the overall noise level.

of 57

5.4 Noise Sources and Sound Power Levels

Sound Power Levels of the plant and equipment, other than for the asphalt plant, have

been obtained from direct measurements at similar sites elsewhere which are contained on

the WBM plant noise database.

For the asphalt plant data it is proposed that a plant supplied by Ammann is installed.

Information on the plant to be supplied by Ammann has been considered by WBM for

increasing levels of sound insulation mitigation installed on the plant. For the purposes of

the noise assessment, the highest level of noise mitigation possible has been proposed for

the plant, requiring the need for burner and stack silencers and cladding of the plant in

order to enclose the significant noise sources.

The noise assessment has been undertaken for in accordance with BS 4142:2014, with the

assessment time being 1 hour for daytime and 15 minutes for night-time. It has been

assumed in the calculation that certain noise sources, i.e. the Cement Tanker Delivery and

Vibrating Sand Hopper will not operate continually over 1 hour. For the night-time activities,

the loading shovel will be operated in the same way as during the daytime, and therefore

the split of 25% and 75% for on ramp and off ramp activities will remain the same over any

15 minute period.

The gully waste process involves the tipping of water and waste matter from a gully waste

collection vehicle into an enclosed concrete storage area. Waste water will percolate

through a series of filters and into a storage tank. The remaining solids will be removed by

loading shovel to another bay for further drying, before being removed from site. The only

plant associated with the process is a pump which is located in an underground chamber

and will operate occasionally when triggered by a float switch. It is considered by WBM that

the gully waste process will not generate significant noise levels at the closest dwellings to

the site and as such has not been included in the noise calculations for this assessment.

The plant items used in the calculations for this noise assessment are listed in the

summary site noise calculation sheet in Appendix F along with the Sound Power Levels

used in the calculations. The plant items are also summarised below, with the percentage

on-times for daytime and night-time operation.

5.5 Site Noise Mitigation

For the purposes of the noise assessment, the highest level of noise mitigation possible

has been proposed for the asphalt plant, requiring the need for burner and stack silencers

and cladding of the plant in order to enclose the significant noise sources. The asphalt

plant suppliers have committed to a noise level of 48 dB LAeq, T at 100 metres.

The proposed layout of the site has been designed such that a significant barrier will be

constructed between the site and the closest dwellings to the west on Elphick Road and the

southwest on North Way. The proposed layout is shown in the plan in Appendix C.

As shown, covered storage bays at a height of 15 metres are proposed for the south

western parts of the site. The RAP shed is shown in the plan as adjacent to the storage

bays on the southern boundary and is proposed to be a height of 10 metres. On the

western boundary of the site, to the north of the covered storage bays, an acoustic barrier

is proposed at a height of 4.5 metres. To allow for the passage of HGVs on the access

road during the daytime period, this noise barrier is arranged such that there is a step in the

barrier to allow lorries to pass round the storage bays whilst maintaining the barrier effect.

are also shown in the tables. The calculated noise levels below assume soft ground

attenuation and barrier attenuation due to the site layout, described above and shown in

5.7 Assessment of Absolute Noise Levels

The calculated site noise levels shown in Section 5.6 can be compared with the guideline

values for external noise set out in British Standard 8233 and the World Health

Organisation document “Guidelines for Community Noise 1999”, details of which are

presented in Section 2 of this report.

of 57

In BS8233:2014 the document states that for traditional external areas that are used as

amenity spaces (e.g. gardens) it is desirable that external noise does not exceed 50 dB

LAeq,T with an upper guideline value of 55 dB LAeq,T, which would be acceptable in noisier

environments.

The WHO document sets out guideline values for external noise for daytime and night-time,

which are 50-55 dB LAeq,T for daytime and 45 dB LAeq,T for night-time

The following tables present a comparison between the lowest guideline values and the

calculated site noise levels in Section 5.6. In all cases the calculated site noise level is

below the relevant criterion by between 5 and 13 dB.

6 BS 4142: 2014 Assessment

An assessment has been undertaken in accordance with BS 4142: 2014 “Methods for

Rating and assessing industrial and commercial sound” for the nearest existing dwellings to

the proposed development site. The information to be reported, as specified in Section 12

of BS 4142: 2014, is set out below where relevant.

6.1 (a) Source Being Assessed

1) Description of the main sound sources and of the specific sound

The development to be assessed has an asphalt plant, concrete batching plant and gully

waste operation, along with associated vehicle movements.

For the asphalt plant itself the main sources of noise are the burner and drum, the stack

exhaust, high level elevator and mixing town. Also associated with the operation of the

plant is a loading shovel that is used to loading the feed hoppers for the plant, and lorries

being loaded and transporting asphalt off site.

For the concrete batching plant the main sources of noise are the movement and loading of

mixer trucks, the operation of a loading shovel to feed the plant with sand and aggregate,

and the mixing operation inside the concrete batching plant. The delivery of cement to the

site will also occur.

For the gully waste operation, this involves the tipping of water and waste matter from

roadside gully cleaning vehicles into an enclosed concrete area for storage and drying. The

only plant associated with the process is a pump located inside and underground chamber

and the occasional operation of the loading shovel to remove solids to a separate bay for

further drying. This operation of the loading shovel will only be during the daytime.

2) Hours of operation

It is proposed by FM Conway that the following elements of the development can have

unrestricted hours of working;

The manufacture and distribution of asphalt

The importation of road planings and returned loads

The use of the gully waste plant and associated HGV movements

of 57

Other elements of the proposed development, most significantly in noise terms the

concrete batching plant and the delivery of materials, are proposed to be restricted to

between the hours of 7 am to 7 pm Monday to Friday and 7 am to 1 pm Saturdays.

3) Mode of operation (e.g. continuous, twice a day, only in hot weather)

The proposed operations could occur continuously during the proposed hours of operation.

4) Statement of operational rates of the main sound sources (e.g. maximum load setting,

50% max rate, low load setting)

The operational rates for the main sound sources are presented in Section 6.3.

5) Description of premises in which the main sound sources are situated (if applicable).

The proposed development site is a flat plot of land that is currently unused. The location of

the site is shown in Appendix B and the proposed layout of the site is shown in Appendix C.

6.2 (b) Subjective Impressions

1) Dominance or audibility of the specific sound

As the site is not yet operational, it is not possible to present subjective impressions, but

the operation of the asphalt plant and associated loading shovel could be audible during

the night-time. During the daytime the proposed activities will be similar in nature to current

operations that occur at the industrial premises that surround the site, i.e. asphalt plant and

the movement of large mobile plant associated with scrap metal facilities.

2) Main sources contributing to the residual sound.

The main sources contributing to the residual sound levels at receptors near to the

proposed development site during the daytime are road traffic, activity at industrial units,

plant noise from the Veolia energy from waste site, and local residential activity.

During the night-time period the residual sound levels were road traffic and plant noise from

the Veolia energy from waste site.

6.3 (c) The Existing Context and Sensitivity of Receptor

In general the receptors are situated in or close to a town centre and are affected by

vehicle movements associated with the town centre. The North Quay Industrial Estate on

which the proposed site development is also located close to the town centre. The town is

also a port and ship movements regularly occur in and out of port on the River Ouse.

of 57

6.4 (d) Measurement Locations and Justification

Measurement locations, their distance from the specific sound source, the topography of the

intervening ground and any reflecting surface other than the ground, including a photograph, or a

dimensioned sketch with a north marker. A justification for the choice of measurement locations

should also be included.

As the site is yet to be constructed, the specific sound sources for this application are not

on site and able to be measured. Apart from the asphalt plant, the specific sound sources

for this application have been taken from noise measurements from other sites surveyed by

WBM and stored in a database.

For the asphalt plant data has been supplied by Ammann for increasing levels of sound

insulation mitigation installed on the plant. For the purposes of the noise assessment, the

highest level of noise mitigation possible has been proposed for the plant, requiring the

need for burner and stack silencers and cladding of the plant in order to enclose the

significant noise sources.

An aerial photograph marked with the closest receptors to the proposed development is

presented in Appendix B. In Appendix C is the proposed layout of the development. In

general the site and the surrounding North Quay Industrial Estate is flat. Generally to the

west and east of the site where the receptors are located the ground height rises.

6.5 (e) Sound Measuring Systems, Including Calibrator / Pistonphone

Details of survey equipment are presented in Appendix D.

6.6 (f) Operational Test

The calibration levels for each of the surveys undertaken are set out in Appendix D.

6.7 (g) Weather Conditions

Details of weather conditions during surveys is presented in Appendices D and E.

6.8 (h) Date(s) and Time(s) of Measurements

Survey details presented in Appendix D

6.9 (i) Measurement Time Intervals

of 57

Survey details presented in Appendix D

6.10 (j) Reference Time Interval(s)

The reference time interval is 1 hour for a daytime assessment between 07:00 and 23:00

hours and a period of 15 minutes for a night-time assessment between 23:00 and 07:00

hours.

6.11 (k) Specific Sound Levels

Items 1 to 4)

The specific sound levels for the asphalt plant and concrete batching plant proposed at the

site have been calculated using the methods set out in BS 5228-1: 2009 + A1: 2014. The

sound powers used in the calculation are presented in Section 5.4 and details of the

calculation and an example calculation sheet are presented in Appendix F.

5) Justification of methods

As the proposed plant at the site at North Quay cannot be measured it is justified to use

calculations to determine the specific level, taking into account mitigation provided by

barriers.

6) Details of any corrections applied

See the Potential Impact of Uncertainty section.

6.12 (l) Background Sound Level(s)

Background sound level(s) and measurement time interval(s) and, in the case of

measurements taken at an equivalent location, the reasons for presuming it to be

equivalent.

The representative background sound level for the daytime and night-time at the selected

receptors is presented in Section 4.

6.13 (m) Rating Level(s)

1) Specific sound level(s)

The specific sound levels are stated in Section 5.6 Calculated Levels.

of 57

2) Any acoustic features of the specific sound

The adjustments for the different features and assessment methods are summarised in the

table below.

Acoustic Feature

Adjustment for Acoustic Feature

Subjective Methods Objective Methods

Tonality +2 dB if just perceptible



Third Octave Analysis Narrow Band Analysis

+6 dB if tones identified Sliding scale of 0 to +6 dB depending on audibility of tone

Impulsivity +3 dB if just perceptible



Sliding scale of 0 to +9 dB depending on prominence of impulsive sound

Intermittency + 3 dB if intermittency is readily distinctive

n/a

Other + 3 dB if neither tonal nor impulsive, but otherwise readily distinctive

n/a

For the asphalt plant the plant will be designed with external cladding and noise reduction

measures put in place to minimise the possibility of tonal or impulsive noise being emitted

by the operation of the plant.

A loading shovel will need to be operated to feed the asphalt plant via the feed hoppers and

typically a loading shovel will have occasional impulsive noise associated with the tipping

aggregate from the shovel bucket. Any impulsive noise associated with the loading shovel

will be screened from the closest receptors to the west and southwest by the covered

storage bays. To the northeast there is significant separation distance between the site and

the receptors and any impulsive noise associated with the loading shovel will be screened

in this direction by the canopy over the feed hoppers. This noise mitigation will reduce the

occasional impulsive noise from the site.

For the concrete batching plant it is generally the case that this type of operation does not

have impulsive or tonal feature characteristics associated with the operation that would be

distinguishable at the surrounding dwellings.

The delivery of material during daytime hours could give rise to an acoustic feature that is

neither tonal nor impulsive, but otherwise readily distinctive, with a correction of + 3 dB.

of 57

3) Rating level(s)

For the asphalt plant operation at night, taking into account the mitigation measures

discussed in (2), no acoustic feature correction is required and therefore the rating level is

equal to the specific noise level.

For the overall site operation for the daytime, the rating level is 3 dB above the specific

noise level, as determined in accordance with BS 4142: 2014.

6.14 (n) Excess of the rating level(s) over background sound level(s)

Excess of the rating level(s) over the measured background sound level(s) and the initial

estimate of the impacts

The calculation of the excess of the rating level over the measured background sound level

is presented in Appendix G for all receiver locations, for the daytime and night-time periods.

The table below summarises the calculated excess of the rating level over the background

noise level.

Daytime

Location Excess of Rating Level over Background (dB)

71 Elphick Road +1

Bridge Court -5

Avis Road -2

65 Beresford Road +4

Lee Court, Elphick Road +4

Night-time

Location Excess of Rating Level over Background (dB)

71 Elphick Road +1

Bridge Court +3

Avis Road +2

65 Beresford Road +4

Lee Court, Elphick Road +2

of 57

When the rating level is above the background sound level, a difference of around +5 dB is

likely to indicate an adverse impact and a difference of around +10 dB or more is likely to

indicate a significant adverse impact, depending on the context.

The lower the rating level with respect to the background sound level, the less likely it is

that the specific sound source will have an 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.

For the daytime, the values in the table show that the excess of rating level over

background indicates at or below adverse impact for Elphick Road, Beresford Road and

Lee Court, i.e. +1 dB to +4 dB and a low impact for all other receptors.

For the night-time, the values in the table show that the excess of rating level over

background indicates at or below adverse impact, i.e. +1 dB to +4 dB.

6.15 (o) Conclusions of the assessment after taking context into account

The conclusion of the assessment is as follows;






6.16 (p) The potential impact of uncertainty

Section 10 of BS 4142:2014 states: “Consider the level of uncertainty in the data and

associated calculations. Where the level of uncertainty could affect the conclusion, take

reasonably practicable steps to reduce the level of uncertainty. Report the level and

potential effects of uncertainty.”

The site noise calculations use noise levels based on data provided by Ammann and

measured at other sites and includes on-times and plant locations that represent a realistic

worst case scenario. The largest level of uncertainty is whether the noise levels calculated

at the residences and the rating levels are achieved once the site is operational.

7 Summary and Conclusions

PDE Consulting Limited is preparing to submit a planning application and associated

information on behalf of FM Conway Limited to erect an asphalt plant, concrete batching

plant, gully waste processing area and ancillary development and access on land off North

Quay Road, Newhaven.

It is proposed by FM Conway Limited that they have the ability to operate the asphalt plant

at any time for the manufacture and distribution of asphalt, along with the importation of

road planings and returned loads of asphalt and the discharge from tankers at the gully

waste processing area. It is proposed to restrict the other plant operations and material

importation to the hours of 7 am to 7 pm Monday to Friday and 7 am to 1 pm on Saturdays.

The report addresses the environmental noise implications of the proposal by setting out

the findings of noise measurements at the nearest properties to the site; discussing the

existing noise climate, and presenting the calculated noise levels arising from the proposed

operations. The calculated noise levels have been compared with guideline values set out

in BS 8233:2014 and the WHO document “Guideline on Community Noise 1999”. An

assessment of the calculated noise levels has also been carried out in accordance with

British Standard 4142:2014.

Noise mitigation measures have been designed into the layout of the site, such that the

closest noise sensitive receptors are screened from the site operations by the covered

storage bays and an acoustic barrier.

With regard to the absolute criteria for external noise presented in BS8233 and the WHO

document, in all cases the calculated site noise is below the relevant criterion by between

5 and 13 dB.

Appendix A – Glossary of Acoustic Terms

The following section describes some of the parameters that are used to quantify noise.

Decibels dB

Noise levels are measured in decibels. The decibel is the logarithmic ratio of the sound pressure to a reference pressure (2x10-5 Pascals). The decibel scale gives a reasonable approximation to the human perception of relative loudness. In terms of human hearing, audible sounds range from the threshold of hearing (0 dB) to the threshold of pain (140 dB).

A-weighted Decibels dB(A)

The ‘A’-weighting filter emulates human hearing response for low levels of sound. The filter network is incorporated electronically into sound level meters. Sound pressure levels measured using an ‘A’-weighting filter have units of dB(A) which is a single figure value to represent the overall noise level for the entire frequency range.

A change of 3 dB(A) is the smallest change in noise level that is perceptible under normal listening conditions. A change of 10 dB(A) corresponds to a doubling or halving of loudness of the sound. The background noise level in a quiet bedroom may be around 20 –30 dB(A); normal speech conversation around 60 dB(A) at 1 m; noise from a very busy road around 70-80 dB(A) at 10m; the level near a pneumatic drill around 100 dB(A).

Façade Noise Level

Façade noise measurements are those undertaken near to reflective surfaces such as walls, usually at a distance of 1m from the surface. Façade noise levels at 1m from a reflective surface are normally around 3 dB greater than those obtained under freefield conditions.

Freefield Noise Level

Freefield noise measurements are those undertaken away from any reflective surfaces other than the ground

Frequency Hz

The frequency of a noise is the number of pressure variations per second, and relates to the “pitch” of the sound. Hertz (Hz) is the unit of frequency and is the same as cycles per second. Normal, healthy human hearing can detect sounds from around 20 Hz to 20 kHz.

Octave and Third-Octave Bands

Two frequencies are said to be an octave apart if the frequency of one is twice the frequency of the other. The octave bandwidth increases as the centre frequency increases. Each bandwidth is 70% of the band centre frequency.

Two frequencies are said to be a third-octave apart if the frequency of one is 1.26 times the other. The third octave bandwidth is 23% of the band centre frequency.

There are recognised octave band and third octave band centre frequencies. The octave or third-octave band sound pressure level is determined from the energy of the sound which falls within the boundaries of that particular octave of third octave band.

of 57

Appendix A (continued)

Equivalent Continuous Sound Pressure Level LAeq,T

The ‘A’-weighted equivalent continuous sound pressure level LAeq,T, is a notional steady level which has the same acoustic energy as the actual fluctuating noise over the same time period T. The LAeq,T unit is dominated by higher noise levels, for example, the LAeq,T average of two equal time periods at , for example, 70 dB(A) and 50 dB(A) is not 60 dB(A) but 67 dB(A).

The LAeq,T unit was commended by the Noise Advisory Council and is the chosen unit of BS5228 for Construction and Open site noise and BS 7445 for the Description and Measurement of Environmental noise.

Maximum Sound Pressure Level LAmax

The LAmax value describes the overall maximum ‘A’-weighted sound pressure level over the measurement interval. Maximum levels are measured with either a fast or slow time weighted, denoted as LAmax,f or LAmax,s respectively.

Sound Exposure Level LAE or SEL

The sound exposure level is a notional level which contains the same acoustic energy in 1 second as a varying ‘A’-weighted noise level over a given period of time. It is normally used to quantify short duration noise events such as aircraft flyover or train passes.

Statistical Parameters LN

In order to cover the time variability aspects, noise can be analysed into various statistical parameters, i.e. the sound level which is exceeded for N% of the time. The most commonly used are the LA01,T, LA10,T and the LA90,T.

LA01,T is the ‘A’-weighted level exceeded for 1% of the time interval T and is often used to gives an indication of the upper maximum level of a fluctuating noise signal.

LA10,T is the ‘A’-weighted level exceeded for 10% of the time interval T and is often used to describe road traffic noise. It gives an indication of the upper level of a fluctuating noise signal. For high volumes of continuous traffic, the LA10,T unit is typically 2–3 dB(A) above the LAeq,T value over the same period.

LA90,T is the ‘A’-weighted level exceeded for 90% of the time interval T, and is often used to describe the underlying background noise level. It is defined in British Standard 4142 as the background sound level and is used for establishing the reference against which industrial and commercial sound is assessed.

Appendix F – Sample Site Noise Calculation Summary Sheet

Specific noise levels are predicted or measured in terms of the Equivalent Continuous Noise Level,

LAeq,T over a given reference time interval, T. In British Standard 4142:2014 the assessment time

interval is 1 hour for daytime and 15 minutes for night-time. For daytime activities, a percentage

on-time has been assigned to each plant item to represent the amount of time they could operate

during a 1 hour period. In the calculation for night-time activities the percentage on-time for the

various plant items have been set to 100% as it is possible that they could operate continually

throughout a 15 minute period.

The calculation method for any plant which is relatively fixed in location is that set out in BS 5228-

1: 2009 + A1: 2014, Annex F, and is the “Method for activity LAeq” described in section F.2.2 or the

“Method for plant sound power level” described in section F.2.3.

The calculation method for site mobile plant such as lorries and dump trucks is that set out in

BS 5228-1: 2009 + A1: 2014, Annex F, and is the “Method for mobile plant in a defined area”

described in section F.2.4 or “Method for mobile plant using a regular well defined route (e. g. haul

roads)” described in section F. 2. 5.

Ground Absorption has been calculated using the technique set out in BS 5228-1: 2009 + A1:

2014, Annex F, assuming between 25% and 45% soft ground between the site operations and the

receiver locations.

The method of assessing screening is that attributed to Maekawa as used in BS 5228-1: 2009 +

A1: 2014, Annex F and various other Government published documents. This method uses the

calculated path difference and octave band noise data for each noise source over the frequency

range stated in BS 5228-1: 2009 + A1: 2014, Annex F.

The effects of ground absorption are not used in the calculations if screening has been assessed

and offers a higher attenuation.

The nearest distances to the respective dwellings, from the various items of plant, have been used

in an acoustic model for the site to calculate the reasonable worst case LAeq,T site noise levels.

A summary site noise calculation sheet for one of the five receiver locations, is included below.

Appendix H – Summary of Noise Mitigation Measures

It is proposed by FM Conway Limited that they have the ability to operate the asphalt plant at any

time for the manufacture and distribution of asphalt, along with the importation of road planings

and returned loads of asphalt and the discharge from tankers at the gully waste processing area.

The Planning Noise Advice Document: Sussex states,

“The rating level of the plant/process, when measured in accordance with BS4142:2014, should,

where practicable, be no greater than the existing background levels when measured in

accordance with BS4142:2014.

Where these criteria are not attainable, the noise report should explain why, and how best

practicable means will be implemented to control noise in order to satisfy the LPA that the

development is acceptable.”

For this development, it is not practicable for the rating levels of the plant/process to be no greater

than the existing background levels when measured in accordance with BS4142:2014.

Accordingly, best practicable means will be implemented to control noise.

Information on the plant to be supplied by Ammann has been considered by WBM for increasing

levels of sound insulation mitigation installed on the plant. For the purposes of the noise

assessment, the highest level of noise mitigation possible has been proposed for the plant,

requiring the need for burner and stack silencers and cladding of the plant in order to enclose the

significant noise sources.

The asphalt plant suppliers have committed to a noise level of 48 dB LAeq, T at 100 metres.

The proposed layout of the site has been designed such that a significant barrier will be

constructed between the site and the closest dwellings to the west on Elphick Road and the

southwest on North Way.

Covered storage bays at a height of 15 metres are proposed for the south western parts of the site.

The RAP shed is shown in the plan as adjacent to the storage bays on the southern boundary and

is proposed to be a height of 10 metres.

The canopy on the eastern side of the cold feed hoppers is taken to be a height of 7 metres.

On the western boundary of the site, to the north of the covered storage bays, an acoustic barrier

is proposed at a height of 4.5 metres.

of 57

To allow for the passage of HGVs on the access road during the daytime period, this noise barrier

is arranged such that there is a step in the barrier to allow lorries to pass round the storage bays

whilst maintaining the barrier effect.

No HGVs will use the access road to the west of the covered storage bays other than between the

hours of 6 am to 11 pm (see Appendix I).

At night, the tipping of imported road planings and returned loads of asphalt will take place inside

the recycled asphalt planings (RAP) building. This activity is not included in the site noise

calculations as it is assumed to be insignificant, so long as it is road planings only and tipping

occurs inside the RAP building at night.

The discharge from tankers at the gully waste processing area will take place at night but the

occasional operation of the loading shovel to remove solids will be a daytime operation only.

Other elements of the proposed development, most significantly in noise terms the concrete

batching plant and the delivery (importation) of materials, are proposed to be restricted to between

the hours of 7 am to 7 pm Monday to Friday and 7 am to 1 pm Saturdays.

It is important that the asphalt plant noise at the assessment locations does not contain acoustic

features (as described in BS 4142: 2014 Section 9) for example the mitigation to the major noise

sources should be designed such that the noise emanating from the plant / stack exhaust does not

contain significant tonal components.

Other aspects of plant noise / operational constraints are set out below

A vibrating feed hopper should not be used, particularly at night

The feed hoppers shall be lined with appropriately selected ‘damping’ material

A ‘roots’ blower for filler should not be used unless adequately enclosed

The gear box / motor at the top of the hot elevator should be enclosed

Any reverse air jet at the top of the hot elevator should be silenced

Scraping of the loading shovel bucket on the ground must not occur at night

Plant start-up alarms and sirens must be suitably designed

There should be no use of a tannoy system at the site

There should be no use of HGV horns at the site

Any HGVs that need to reverse on site at night must be fitted with appropriate reversing alarms

of 57

Appendix I – HGV Movements in Period 6 am to 7 am

There is a requirement for HGVs to use the access road west of the aggregate storage bays

before 7 am. In the context of BS4142: 2014, the period 6 am to 7 am is within the night-time

period 11 pm to 7 am.

Accordingly, a separate BS 4142: 2014 Summary has been prepared below for the period 6 am to

7 am, for inspection.

The specific sound level includes the asphalt plant operations, vehicle movements, tipping within

the RAP building, gully waste operation and vehicle movements to the west of the aggregate

storage bays.

The background sound level for the period 6 am to 7 am is the 25th percentile value from both

installed sound level meters for all data for the period 6 am to 7 am.
