1 Introduction
Davies Planning is preparing to submit a planning application and associated information
on behalf of Brett Group for proposed aggregate importation and processing and the
preparation and manufacture of value added products at Fisher’s Wharf East Quay
Newhaven Port.
Aggregate processing and bagging and ready-mixed concrete production and deliveries by
road would be carried out Monday to Friday (excluding public holidays) between 07:00 and
18:00 hours and on Saturday between 07:00 and 13:00 hours. Train loading would be
carried out Monday to Saturday between 06:00 and 20:00 hours. Only essential
maintenance would normally be carried out outside these hours. Production of concrete
blocks is a continuous operation would be carried out between 00:00 on Monday and 13:00
hours on Saturday. No operations at the concrete block making plant would be carried out
in the open after 22:00 or before 07:00 hours the following day.
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 and listed in Appendix L “EIA Regulations 2017 Schedule 4 Summary”.
2.1 Local Planning Authority
The proposed development site falls under the jurisdiction of East Sussex County Council
(ESCC). ESCC is listed as one of fifteen councils in the document “Planning Noise Advice
Document: Sussex” (July 2015).
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.
Page 6 of 61
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.
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:
Page 7 of 61
• 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.”
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.
Page 8 of 61
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).
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
+6 dB if clearly perceptible
+9 dB if highly 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.
Page 9 of 61
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:
Page 10 of 61
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.
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.
Page 11 of 61
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.
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.
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.
Page 12 of 61
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…”
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.
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.

2.6 WBM Scope of Noise Assessment
In a Scope of Noise Assessment prepared by WBM on 02 August 2016 it is stated:
The nearest noise sensitive properties to the proposed application site are those on the
west side of the River Ouse adjacent to Fort Road at a separation distance of about 150
metres to the proposed location of vessel unloading and about 300 m to the main part of
the site. There are dwellings about 1 km to the north east of the site beyond the A259
Seaford Road.
Adequate baseline data will be obtained to represent the existing noise climate at these
receiver locations, see Methodology, at four positions that are accessible by public road or
footpath.
Source data will be obtained for the self-discharging vessel, rail loading, proposed washing
and bagging plant associated with the proposal and for mobile plant such as a hydraulic
excavator for loading the train and a wheeled loading shovel for moving material.
Site noise calculations will be undertaken for four receiver locations, taking into account the
source data and separation distances, without any barriers or other mitigation included.
Where necessary, barriers or additional mitigation will be explored to demonstrate
compliance by way of calculation with appropriate noise limits for the proposed daytime
hours of operation (typically 07:00 to 18:00 hours on weekdays) and for potential night-time
hours of operation for the self-discharging vessel.
Methodology
Attended sample measurements of 15-minute duration will be made at four positions that
are accessible by public road or footpath, as shown on the map extracts on the next page.
There will be 8 measurements taken during the proposed daytime hours of operation on
two days i.e. a total of sixteen 15-minute sample measurements, to represent the baseline
noise climate for daytime.
There will be 8 15-minute sample measurements taken during the night-time to represent
the baseline noise climate for night-time.
Page 14 of 61
Source data will be obtained for the self-discharging vessel, rail loading, proposed washing
and bagging plant associated with the proposal and for mobile plant such as a hydraulic
excavator for loading the train and a wheeled loading shovel for moving material, from
supplier’s / manufacturer’s data sheets or from the WBM plant noise database of
measurements on similar plant and equipment.
Site noise calculations will be undertaken for the four selected receiver locations, without
any barriers or other mitigation included, using the methods contained in
BS5228:2009+A1:2014 Annex F “Estimating noise from sites”.
The output from the site noise calculations for the four dwellings will be compared with a
suggested site noise limit for each dwelling which will be 5 dB(A) above the average
background sound level derived above.
Where necessary, barriers or additional mitigation will be explored to demonstrate
compliance by way of calculation with appropriate noise limits for the proposed daytime
hours of operation (07:00 to 18:00 hours on weekdays) and for potential night-time hours of
operation for the self-discharging vessel.
The baseline measurements, source terms, site noise calculations and consideration of
barriers or additional mitigation will be set out in sufficient detail to allow for proper
inspection and checking by East Sussex County Council.
3 Site Description
The proposed site is at Fisher’s Wharf, East Quay, Newhaven Harbour which is located on
the south coast of England at the mouth of the River Ouse to the south of the town of
Newhaven in East Sussex.
The site is bounded to the north by Mill Creek, to the west by an area of warehouses, to the
south west by the Rampion development site, to the south by the Port Expansion Area and
to the east by an area of open ground.
The closest dwellings are described in Section 2.6 and the location of the site and the
residential properties are shown on a plan in Appendix B.
If this development were not to proceed the area would be developed by the Port Authority,
for example buildings and associated area to extend the dock facilities.

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;
The Hope Inn
Newhaven Marina
Cyclepaths A259
Marine Drive Footpath
Sound level meters were also installed at the following locations;
Newhaven Marina
Marine Drive
Details of the attended and install survey positions are shown on a marked plan and
described in Appendix B. The proposed site development layout is shown in Appendix C.
An initial site visit was undertaken on Thursday 18 August 2016 to obtain sample
measurements near to the selected dwellings, as detailed above. Attended sample
measurements were taken during the subsequent night-time period, into Friday 19 August
2016. Further measurements of the existing noise climate were made during the daytime
on Thursday 25 August 2016.
Data logging sound level meters were installed at the locations detailed above on Thursday
18 August 2016 and Friday 19 August 2016 and collected on Thursday 25 August 2016.
The meters measured the noise climate for at least 6 days, including a weekend period.
The wind picked up on Friday 19 August 2016 in the afternoon and it was forecast to be
windy on Saturday and Sunday, with the wind dropping on Monday and relatively light
winds on Tuesday, Wednesday and both Thursdays.
The survey, instrumentation and calibration details are included as Appendix D and the
attended noise survey and results from the installed meters are set out in Appendix E.
Attended sample measurements of 15-minute duration were made at four positions, that
are accessible by public road or footpath, as shown on the map extracts in Appendix B.
Page 16 of 61
There were 8 measurements taken during the proposed daytime hours of operation on two
days i.e. a total of sixteen 15-minute sample measurements, to represent the baseline
noise climate for daytime at positions 1 to 4. The daytime samples were made on Thursday
18 August 2016 and Thursday 25 August 2016.
There were eight 15-minute sample measurements taken during the night-time to represent
the baseline noise climate for night-time at the four positions. The night-time samples were
made between Thursday 18 August 2016 and Friday 19 August 2016. A summary of the
attended sample measurements baseline survey results in shown in the table below.

Two sound level meters were installed at secure locations to obtain longer term unattended
data for the dwellings on the west side of the River Ouse and those beyond the A259
Seaford Road, between 18/19 August 2016 and Thursday 25 August 2016.
The microphones for the meters were installed on the flat roof of a building outside the
offices at Newhaven Marina (position A) and in the rear garden of a dwelling on Marine
Drive (position B).
The results from the meter installed on the flat roof of a building outside the offices at
Newhaven Marina (position A) are presented graphically and in tabular form in Appendix E.
The results from the meter installed in the rear garden of a dwelling on Marine Drive
(position B) are presented graphically and in tabular form in Appendix E.
A summary of the baseline survey results for the install locations for 7 am to 6 pm Monday
to Friday and 7 am to 1 pm on Saturdays is shown in the table below.

The measured background noise levels for the night-time period 11 pm to 7 am varied
significantly for the install meters, depending on wind speed, time of night, traffic on the
A259 for measurements at Marine Drive and scrap metal loading activity at the Port of
Newhaven for measurements at Newhaven Marina. The lowest, average and highest
measured background noise levels are presented below for the install meters.

For the purposes of the BS4142 assessment, the 25 percentile levels have been calculated
from the install meters which it is believed provides representative background sound
levels rather than using average values for the daytime and night-time periods.

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.
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 summary site noise 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 proposed development would be carried out in the areas shown on the drawing in
Appendix G. All that part of the development site which is to the west of the application site,
i.e. where offloading of aggregates from sea going vessels, their storage and rehandling
would be carried out, is carried out under the permitted development rights enjoyed by the
statutory harbour authority and its lessees. Consequently this land (shown in blue on the
drawing) is not part of the application site (shown in red on the drawing).
The main operations that are proposed to occur at the application site are as follows;
Crushing, screening and washing of aggregate in processing plant
Concrete batching plant and associated activities / deliveries
Bagging plant inside an existing building
Concrete block making plant inside a building
Train loading by wheeled loader (loading shovel)
Feeding hoppers by wheeled loader (loading shovel)
HGV loading by wheeled loader (loading shovel)
Material export from the site

5.4 Noise Sources and Sound Power Levels
The noise assessment has been undertaken in accordance with BS 4142:2014, with the
assessment time being 1 hour for daytime and 15 minutes for night-time. 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 at each selected receiver location. Sound Power Levels of the plant and
equipment that is proposed have been obtained from direct measurements at similar sites,
contained on the WBM plant noise database.
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. This information is summarised below.

The calculated site noise levels, dB LAeq,1 hour, free field for each of the receiver locations is
presented below for daytime and night-time periods. The assumed receiver heights for
each period are also shown in the tables. The calculated noise levels below assume 5%,
60% or 90% soft ground attenuation and barrier attenuation due to the site layout.

5.6 Assessment of Absolute Noise Levels
The calculated site noise levels shown in Section 5.5 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.
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
Page 21 of 61
The following tables present a comparison between the lowest guideline values and the
calculated site noise levels in Section 5.5.

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 is the crushing and washing of aggregate in a processing
plant; concrete batching plant and associated activities; bagging plant; concrete block
making plant, train wagon loading and HGV loading; material export from the site.
Page 22 of 61
2) Hours of operation
Aggregate processing and bagging and ready-mixed concrete production and deliveries by
road would be carried out Monday to Friday (excluding public holidays) between 07:00 and
18:00 hours and on Saturday between 07:00 and 13:00 hours. Train loading would be
carried out Monday to Saturday between 06:00 and 20:00 hours. Only essential
maintenance would normally be carried out outside these hours. Production of concrete
blocks is a continuous operation would be carried out between 00:00 on Monday and 13:00
hours on Saturday. No operations at the concrete block making plant would be carried out
in the open after 22:00 or before 07:00 hours the following day.
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 Sound Power Levels for the main sound sources are presented in Appendix F.
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 could be audible during the daytime at the nearest dwellings.
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, local activity and adjacent
commercial and industrial uses.
During the night-time period the residual sound levels were most notably affected by scrap
metal loading at the H Ripley & Co site.
Page 23 of 61
6.3 (c) The Existing Context and Sensitivity of Receptor
The receptors to the west of the River Ouse are exposed to the noise arising from a vessel
loading scrap metal for 72 hours (day and night) about three times per month. Newhaven is
a port and vessel movements regularly occur on the River Ouse in and out of the harbour.
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.
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 surrounding area is flat and about 5 m above the River Ouse.
6.5 (e) Sound Measuring Systems, Including Calibrator / Pistonphone
As the site is yet to be constructed, the specific sound sources for this application are not
on site and not able to be measured.
Details of survey equipment are presented in Appendix D for the baseline measurements.
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 the attended surveys are presented in Appendix E.
6.8 (h) Date(s) and Time(s) of Measurements
Survey details presented in Appendix D
6.9 (i) Measurement Time Intervals
Survey details presented in Appendix D
Page 24 of 61
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 plant items 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 East 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 levels for the daytime and night-time periods at the
selected receptors is presented at the end of Section 4.
6.13 (m) Rating Level(s)
1) Specific sound level(s)
The specific sound levels are stated in Section 5.5 Calculated Levels.
2) Any acoustic features of the specific sound
The adjustments for acoustic features and assessment methods are summarised below.
Page 25 of 61
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
+6 dB if clearly perceptible
+9 dB if highly 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
The handling and loading of material during daytime hours could give rise to an acoustic
feature that is either just perceptible as impulsive or otherwise readily distinctive at the off-
site receiver locations, with a correction of + 3 dB.
3) Rating level(s)
For the daytime operations, an acoustic feature correction of + 3 dB(A) could be required
and therefore the rating level is equal to the specific noise level + 3 dB(A).
For the site operation for the daytime, the rating level would then be 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 I for all receiver locations, for the daytime period. The table below
summarises the excess of the rating level over the background sound level.
Location of Dwelling Excess of Rating Level over Background Sound Level
Near The Hope Inn + 3
Near Newhaven Marina + 3
Marine Drive + 1
Hurdis Road + 2
Page 26 of 61
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 above show that the excess of rating level over
background indicates below an adverse impact for the four receiver locations and would
avoid noise from giving rise to significant adverse impacts.
For the night-time, the values in the table in Appendix I show that the rating levels are
below the background which indicates a low impact, depending on the context.
6.15 (o) Conclusions of the assessment after taking context into account
For the daytime, the values in the table show that the excess of rating level over
background indicates below an adverse impact for the four receptors. In the context of the
existing operations on East Quay, vessels using the River Ouse and the expansion of
Newhaven Harbour it is considered that this impact is acceptable for daytime operations.
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 measured at other sites and
include on-times and assumptions that have been checked and validated by the operating
company. 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.
For the daytime operations, an acoustic feature correction of + 3 dB(A) could be required
and therefore the rating level is equal to the specific noise level + 3 dB(A). The rating levels
Page 27 of 61
would be equal to the specific noise levels if there was no need for an acoustic feature
correction and this will not be known until the site is operational.
7 Site Noise Calculation for Ecology Site
An area of ecological interest has been identified adjacent to the Brett proposal site, for
which information on noise levels has been requested.
WBM has calculated site noise levels (daytime and night-time) for a point on the Mill Creek
within the Tide Mills SNCI (ref L60).
The point that has been selected for the purpose of calculation is shown by the black arrow
on the top image in Appendix J that also shows the application site boundary.
The site noise calculations for the ecology site exclude all noise sources outside the
application site (red line) boundary.
The calculated site noise levels are 46 dB LAeq, 1 hour, free field for daytime and 38 dB LAeq, 15
minutes, free field for night-time (internal operations only within the concrete block plant).
The noise measurement location plan from the noise section from the ES for the port
expansion development is reproduced on the bottom part of the image in Appendix J.
Measurement location CN7 is “Land at Tidemills South Downs National Park”.
The daytime measurement at CN7 is presented in the ES noise chapter with levels of
53.8 dB LAeq, 1 hour and 41.3 dB LA90, 1 hour.
The night-time measurement at CN7 is presented in the ES noise chapter with levels of
40.7 dB LAeq, 15 minutes and 39.0 dB LA90, 15 minutes.
The calculated site noise levels at the selected point on the Mill Creek for daytime and
night-time are around the same or lower than the baseline sound levels measured at CN7.
8 Construction Phase Noise Impact
The methodology used for the assessment of the construction phase is one that has
calculated noise levels associated with construction activity, for comparison with baseline
Page 28 of 61
noise levels and applicable thresholds of significant effect (determined by reference to
British Standard 5228-1:2009+A1:2014) for construction noise at dwellings.
For construction noise the threshold of a significant effect at dwellings is determined in
accordance with Annex E (informative) of BS5228-1:2009+A1:2014 ‘Code of practice for
noise and vibration control on construction and open sites – Part 1: Noise’.
BS 5228-1:2009+A1:2014 gives recommendations for basic methods of noise control
relating to construction sites, including sites where demolition, remediation, ground
treatment or related civil engineering works are being carried out, and open sites. This part
of BS 5228 provides guidance concerning methods of predicting and measuring noise and
assessing its impact on those exposed to it.
On page 119 Section E.3.2 (reproduced in Appendix K) an example is given of the
threshold of potential significant effect at dwellings, when the site noise level exceeds the
listed value for different time periods. If the construction site noise level is above the
appropriate category value, then a potential significant effect is indicated.
For Daytime (07.00-19.00) and Saturdays (07.00-13.00) the Threshold Value for
Assessment Category A is 65 dB LAeq, T. Assessment Category A is for when ambient noise
levels are below 65 dB LAeq, T.
The Threshold Value for Assessment Category B is 70 dB LAeq, T. Assessment Category B
is for when ambient noise levels equal 65 dB LAeq, T. The Threshold Value for Assessment
Category C is 75 dB LAeq, T. Assessment Category C is for when ambient noise levels are
higher than 65 dB LAeq, T.
Lower Threshold Values are provided for Night-time (23.00-07.00) and for Evenings and
weekends. Evenings and weekends are taken to be 19.00-23.00 weekdays, 13.00-23.00
Saturdays and 07.00-23.00 Sundays.
For these proposals, the averaging times for the Threshold Values are to be the same as
the corresponding period, e.g. 12 hours for Daytime (07:00-19:00) and 6 hours for
Saturdays (07.00-13.00).
During the construction of each stage of development, the minimum of construction plant
would be used, rotary piling techniques would be employed to minimise noise.
Page 29 of 61
No more plant would be on site during the construction of a stage of the development than
when it is in operation. Typically there would be excavators used for foundations and
concrete mixer trucks from time to time, along with lorries to take material from the site.
Cranes would be used for erection of steelwork and pneumatic hand tools.
Assuming on overall Sound Power Level of 115 dB LWA for all construction plant operating
simultaneously and a separation distance of about 300 metres to the nearest dwellings, the
calculated construction noise level is less than 60 dB LAeq, 12 hour, free field.
For Daytime (07.00-19.00) and Saturdays (07.00-13.00) the Threshold Value for
Assessment Category A is 65 dB LAeq, T. Assessment Category A is for when ambient noise
levels are below 65 dB LAeq, T.
The calculated construction noise level for these proposals is below the Threshold Value of
Significant Effect at Dwellings for Weekday Daytime and Saturdays.
The imposition of a planning condition requiring the submission, prior approval and
implementation of a construction management plan is invited.
9 HGV Movements on Beach Road
The baseline traffic flows for Beach Road have been provided to WBM so that the change
in the dB LA10 18 hour road traffic noise level can be calculated for the vehicle movements
associated with the Stage 1 development.
The calculated change in the dB LA10 18 hour road traffic noise level, using the methods
contained within the Calculation of Road Traffic Noise (CRTN) Memorandum 1988, is 0.2
dB(A) for the 34 HGV movements and 52 car movements per day associated with the
Stage 1 development.
The Design Manual for Roads and Bridges (DMRB) Volume II Environmental Assessment
Section 3 Environmental Assessment Techniques Part 7 HD 213/11 Noise and Vibration
dated November 2011, contains Chapter 3 “Procedure for Assessing Impacts”. It is stated
at paragraph 3.37 that, “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”. The contents
of Table 3.1 “Classification of Magnitude of Noise Impacts in the Short Term” are
reproduced below.
Page 30 of 61
Noise change: 0 dB LA10, 18 hour Magnitude of Impact: No change
Noise change: 0.1 – 0.9 LA10, 18 hour Magnitude of Impact: Negligible
Noise change: 1 – 2.9 dB LA10, 18 hour Magnitude of Impact: Minor
Noise change: 3 – 4.9 dB LA10, 18 hour Magnitude of Impact: Moderate
Noise change: 5+ dB LA10, 18 hour Magnitude of Impact: Major
In simple terms, a noise change is calculated using the prediction method in CRTN 1988.
The noise change is then classified by reference to the above contents of Table 3.1 of the
DMRB. The DMRB document describes a noise change of 0.2 dB in the short term as
negligible for magnitude of impact.
Individual HGV movements would generate maximum noise levels corresponding to the
separation distance to dwellings, which is perhaps as little as 5 m for some dwellings on
Beach Road. Whilst the impact of individual HGV movements cannot be described as
negligible, the change in daily road traffic noise is small and the noise change is negligible.
10 Non-Technical Summary
Davies Planning is preparing to submit a planning application and associated information
on behalf of Brett Group for proposed aggregate importation and processing and the
preparation and manufacture of value added products at Fisher’s Wharf East Quay
Newhaven Port.
The noise 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 with extensive mitigation measures incorporated into the development.
If this development were not to proceed the area would be developed by the Port Authority,
for example buildings and associated area to extend the dock facilities.
The effects of the noise from the construction phase would be direct, negative, short-term
and temporary and below the threshold of a significant effect at dwellings.
The effects of the noise from the development would be direct, negative, long-term and
temporary (for the duration of the operations on the site).
Page 31 of 61
The calculated noise levels for the development have been compared with guideline values
set out in BS 8233:2014 “Guidance on sound insulation and noise reduction for buildings”
and the WHO document “Guideline on Community Noise 1999”. The calculated daytime
levels are between 3 and 17 dB(A) below the daytime guideline values. The calculated
night-time levels are between 7 and 21 dB(A) below the night-time guideline values.
An assessment of the development noise levels has also been carried out in accordance
with British Standard BS4142:2014 "Methods for rating and assessing industrial and
commercial sound".
The measured background noise levels for the night-time period 11 pm to 7 am varied
significantly for the install meters, depending on wind speed, time of night, traffic on the
A259 for measurements at Marine Drive and scrap metal loading activity at the Port of
Newhaven for measurements at Newhaven Marina.
For the purposes of the BS4142 assessment, the 25 percentile levels have been calculated
from the install meters which it is believed provides representative background sound
levels rather than using average values for the daytime and night-time periods.
For the daytime operations, an acoustic feature correction of + 3 dB(A) could be required
and therefore the rating level is equal to the specific noise level + 3 dB(A). The rating levels
would be equal to the specific noise levels if there was no need for an acoustic feature
correction and this will not be known until the site is operational.
For the daytime, with the acoustic feature correction included, the excess of rating level
over background indicates below an adverse impact for the four receiver locations and
would avoid noise from giving rise to significant adverse impacts.
In the context of the existing operations on East Quay, vessels using the River Ouse and
the expansion of Newhaven Harbour it is considered that this impact is acceptable for
daytime operations.
For the night-time, the rating levels for the development are below the background which
indicates a low impact, depending on the context and it is considered this impact is
acceptable for night-time operations.
Page 32 of 61
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 free field conditions.
Free field Noise Level
Free field 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.
Page 33 of 61
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.

The sensitivity of the meter was verified on site immediately before and after the survey. The measured calibration levels were as follows:
Survey Date Start Cal End Cal
Thursday 18 August 2016 113.7 dB(A) 113.7 dB(A)
Friday 19 August 2016 113.7 dB(A) 113.9 dB(A)
Thursday 25 August 2016 113.6 dB(A) 113.5 dB(A)
The meters and calibrators are tested monthly against a Laboratory Standard Brüel and Kjær Pistonphone, type 4220 (serial number 375806) and a Norsonic Calibrator, type 1253 (serial number 22906) with UKAS approved laboratory certificate of calibration.
Survey Details
Attended sample measurements of 15 minute duration were taken at four locations. The microphone of the meter, positioned on a tripod, was at a height of between 1.2 and 1.5 metres above local ground level, with a windshield used throughout.

Appendix F – Sample Site Noise Calculation Summary Sheets
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 they would 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 10% and 90% soft ground between the site operations and the
receiver locations to the west and east respectively.
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, for
Stage 3 development and separately for the concrete block making plant Stage 4 development.

Appendix H – Summary of Noise Mitigation Measures
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, if
allowance is made for a modest acoustic feature correction of 3 dB.
Accordingly, best practicable means will be implemented to control noise and it is expected that an
operational noise management and monitoring plan will be required by condition.
Aggregate processing and bagging and ready-mixed concrete production and deliveries by road
would be carried out Monday to Friday (excluding public holidays) between 07:00 and 18:00 hours
and on Saturday between 07:00 and 13:00 hours. Train loading would be carried out Monday to
Saturday between 06:00 and 20:00 hours. Only essential maintenance would normally be carried
out outside these hours. Production of concrete blocks is a continuous operation would be carried
out between 00:00 on Monday and 13:00 hours on Saturday. No operations at the concrete block
making plant would be carried out in the open after 22:00 or before 07:00 hours the following day.
Barrier attenuation attributable to the Rampion O&M Building with an assumed height of 8 m, is
included.
Barrier attenuation attributable to the retaining wall around the BAD storage area, taken to be at a
height of 5 m, is included.
Barrier attenuation attributable to a barrier south of the aggregate processing plant, taken to be at
a height of 5 m, is included.
Barrier attenuation attributable to the bays to the south of the train wagon loading area, taken to be
at a height of 3 m, is included.
Local enclosure / cladding to achieve 10 dB(A) reduction for the screen at the aggregate plant will
be included to achieve a Sound Power Level of 97 dB LWA.
Page 56 of 61
Local enclosure / insulated cladding to achieve 10 dB(A) reduction for the crusher at the aggregate
plant will be included to achieve a Sound Power Level of 97 dB LWA.
The three loading shovels will be selected to achieve a Sound Power Level of 106 dB LWA each.
All feed hoppers will be lined and vibrating hoppers selected to minimize noise generation.
The bagging plant is positioned within an existing building to achieve a reduction of 10 dB(A).
For the cement delivery to the block making plant, the compressor will be enclosed to achieve a
Sound Power Level of 94 dB LWA.
The fork lift trucks at the block making plant will be selected to achieve a Sound Power Level of
95 dB LWA (gas powered rather than diesel).
No operations at the concrete block making plant would be carried out in the open after 22:00 or
before 07:00 hours the following day and all main doors will be kept shut during these times.
The insulation for the walls, roof and walls of the block factory will be selected to ensure that the
night-time noise levels are minimized.
Reversing alarms on the loading shovels and fork lift trucks will be of the ‘white noise’ type.
Scraping of the loading shovel buckets on the ground should be avoided where practical, and prohibited before 07:00 and after 19:00.
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 should be fitted with appropriate reversing alarms.

Appendix L – EIA Regulations 2017 Schedule 4 Summary
Statutory Instruments 2017 No. 571 The Town and Country Planning (Environmental Impact Assessment) Regulations 2017 Schedule 4 Regulation 18(3) Information for Inclusion in Environmental Statements 3. A description of the relevant aspects of the current state of the environment (baseline scenario) and an outline of the likely evolution thereof without implementation of the development as far as natural changes from the baseline scenario can be assessed with reasonable effort on the basis of the availability of environmental information and scientific knowledge. Section 4 “Baseline Noise Surveys” and Appendix E “Noise Survey Data” for baseline scenario. Final sentence in “Section 3 Site Description” for “likely evolution thereof without implementation of the development”. 5. A description of the likely significant effects of the development on the environment resulting from, inter alia: (a) the construction and existence of the development, including, where relevant, demolition works; (c) the emission of pollutants, noise, vibration, light, heat and radiation, the creation of nuisances, and the disposal and recovery of waste; The description of the likely significant effects on the factors specified in regulation 4(2) should cover the direct effects and any indirect, secondary, cumulative, transboundary, short-term, medium-term and long-term, permanent and temporary, positive and negative effects of the development. Contained within Section 5.6 “Assessment of Absolute Noise Levels”; Section 6 “BS 4142: 2014 Assessment”; Section 7 “Site Noise Calculation for Ecology Site”; Section 8 “Construction Phase Noise Impact”; Section 9 “HGV Movements on Beach Road” and Section 10 “Non-Technical Summary”. 6. A description of the forecasting methods or evidence, used to identify and assess the significant effects on the environment, including details of difficulties (for example technical deficiencies or lack of knowledge) encountered compiling the required information and the main uncertainties involved. Contained within Section 5 “Calculated Site Noise Levels”; Section 6.16 “The potential impact of uncertainty”; Section 8 “Construction Phase Noise Impact”; Section 9 “HGV Movements on Beach Road”; Appendix F “Sample Site Noise Calculation Summary Sheets; Appendix K “Extract from BS5228-1:2009 + A1: 2014”.
