TRANSCRIPT
Pannington Farm Wind TurbineNon-Technical Summary (NTS)
December 2013
Context
This Non-Technical Summary (NTS) forms part
of the Environmental Statement (ES) which has
been prepared by AMEC Environment &
Infrastructure UK Ltd (AMEC) on behalf of PfR
(Pannington Farm) Limited (the Applicant) to
accompany a planning application for the
proposed Pannington Farm Wind Turbine
Development (herein referred to as the
‘Proposed Development’) to construct and
operate a single wind turbine on land near
Pannington Farm south of Ipswich (herein
referred to as the ‘Development Site’). The ES
presents the findings of an Environmental
Impact Assessment (EIA) which aims to identify
any potentially significant effects from the
Proposed Development and, where
appropriate, to propose suitable mitigation
measures to address or minimise any effects
identified. This document is a ‘non-technical’
summary of the main findings of the ES.
Background
The Intergovernmental Panel on Climate
Change (IPCC), which is the principal scientific
body advising governments on climate change,
has confirmed the significant influence on the
global climate of increases in atmospheric
levels of carbon dioxide (CO2) and other
greenhouse gases as a result of human
activities.
The burning of fossil fuels such as coal and gas
to generate electricity is a major source of
greenhouse gas emissions. A vital part of
reducing these emissions is increasing the
proportion of electricity generated from
renewable energy sources such as wind.
The Climate Change Act 2008 sets a legally
binding target of at least an 80% cut in UK
greenhouse gas emissions by 2050. In the
shorter term it sets a target reduction in
emissions of at least 34% by 2020. In addition,
as part of EU-wide actions to increase the use
of renewable energy, the UK has a legally-
binding commitment to source 15% of its
energy from renewable sources by 2020.
DECC published the 2020 UK Renewable Energy
Roadmap in July 2011 which sets out a path as
to how the United Kingdom intends to fulfil its
obligation to the European Union of sourcing
15% of its energy from renewables by 2020.
The Roadmap follows the Renewable Energy
Strategy with some changes made in terms of
wind energy deployment scenarios. The
current central scenario for offshore wind sees
scope for 18GW by 2020 with onshore wind
scope for 13GW by 2020.
02
The coalition Government re-affirmed its
commitment to meeting these targets in its Carbon
Plan: Delivering our Low Carbon Future published by
the Department of Energy and Climate Change (DECC)
in December 2011. It has also published the
Electricity Market Reform White Paper (DECC, 2011)
which proposes to overhaul the current electricity
market to create a level playing field for low carbon
technologies by:
Introducing a Carbon Price Floor from April 2013
to reduce investor uncertainty, place a fair price
on carbon and provide a stronger incentive to
invest in low carbon generation now.
Introduce new long-term contracts from 2014
(Feed-in Tariffs with Contracts for Difference) to
provide stable financial incentives to invest in all
forms of low carbon electricity generation. These
will replace the existing Renewables Obligation
(although they will run in parallel with it to 2017);
and
An Emissions Performance Standard set at 450g
CO2 per kWh starting in 2013 to reinforce the
requirement that no new coal-fired power
stations are built without Carbon Capture and
Storage while allowing the necessary short-term
investment in gas to take place.
The targets are set in order to combat climate change
and provide the UK with a more secure energy supply
by reducing reliance on imported fossil fuels. As the
UK has one of the windiest climates in Europe a
significant proportion of the electricity required from
renewables is expected to come from onshore wind
generation. In order to achieve national and regional
targets for renewable energy generation and to
transform the UK to a low carbon economy a range of
large and small scale renewable energy installations
will be required. As such the Proposed Development
will contribute to the attainment of these goals.
Developer and Project Team
Partnerships for Renewables (PfR) was set up by the
Carbon Trust in 2007 to develop, construct and
operate renewable energy projects primarily on
public sector land. Partnerships for Renewables
Development Company Ltd (PfR) was established to
facilitate the development of renewable energy
projects and has set up PfR (Pannington Farm)
Limited, a subsidiary development company, to
progress this project near Pannington Farm.
The EIA has been managed and co-ordinated by
AMEC on behalf of PfR. AMEC Environment &
Infrastructure UK Ltd is one of the UK's largest
environmental and engineering consultancies and
part of a global Environment & Infrastructure division
with 7,000 employees around the world. This
division of the AMEC business delivers
environmental, engineering and related consultancy
services to customers across the public and private
sectors.
AMEC is an Institute of Environmental Management
and Assessment (IEMA) Registered Assessor (the
principle professional body for EIA in the UK) and is
highly experienced in undertaking EIA of wind energy
developments with approximately 1,250MW of
development consented.
Further specialist input came from; Hoare Lea who
carried out the noise assessment and prepared the
ES chapter on noise; Archaeological Services from
Durham University who carried out the geophysical
surveys for the archaeological assessment and
Wynns who carried out the Abnormal Indivisible
Loads Access Survey and Davidson Walsh who were
consulting engineers for scheme design.
03
The Proposed Development
This project was initially named ‘Thorington Barn Wind Energy
Development’ and was developed in partnership with Ipswich
Borough Council (IBC). The Proposed Development is now located
on neighbouring agricultural land forming part of the Pannington
Estate near Belstead, Ipswich (the Development Site) where PfR has
established the viability of constructing a single wind turbine. The
original development area was initially considered for development
(centred on 614000E 240910N) and is shown in Figure 1.1 has been
considered during site surveys undertaken for this ES and has been
included in the results presented in parts of this ES.
Following a range of technical and environmental investigations and
after extensive consultation PfR is proposing a scheme at the
Development Site comprising:
“The erection, 25 year operation and subsequent de-commissioning
of a wind energy development comprising of the following elements:
one wind turbine with a maximum overall height (to vertical blade
tip) of up to 130 metres together with one new vehicular access from
the public highway, new on-site access tracks, associated crane pad
and transformer kiosk, control building and on-site underground
cables, temporary construction compound and laydown area and
other works and development ancillary to the main development.”
The purpose of the Proposed Development is the generation of
electricity. The choice of turbine to be installed will follow a
competitive tendering exercise and will depend on which turbine
models are available in the UK market. A number of turbine models
with an ‘installed capacity’ (the maximum amount of electricity
which can be produced at any one time) of between 2MW and 3MW
and a maximum height to vertical blade tip of 130m are potentially
suitable for the Development Site. The Nordex N100 (2.5MW)
turbine is used as the ‘candidate turbine’ for the purposes of the
Environmental Impact Assessment and for calculating the expected
energy yield.
One wind turbine with a maximum height to vertical blade tip of
130m and an installed capacity of 2.5MW could generate 5.48GWh
of renewable electricity per year. This is equivalent to the amount
of electricity used annually by approximately 1,280 average UK
households and could displace approximately 2,350 tonnes of
carbon dioxide (CO2) equivalent emissions per year1. The
methodology underlying these figures is explained in full in Section
6.2 of Chapter 6.
Pannington Farm Wind

Number of Wind Turbines: 1
Maximum Tip Height
(combined height of blade and
tower): 130m
Estimated Total Generation
Capacity: between 2
megawatts and 3 megawatts1
Estimated Electricity
Generated Per Annum: around
5.4 gigawatt-hours 1
Households Equivalent: 1,280
average UK homes1
04
1 The most recently available data is that in
2011 average domestic electricity
consumption in the UK was 4,266kWh per
household (see cell N400 in 2011 tab of the
Excel spread sheet “Sub-National Electricity
sales and numbers of customers 2005 –
2011” Publication number URN:12D/468
from the Department of Energy and Climate
Change). This consumption figure is also
used by Renewables UK.
It is expected that one turbine with an
installed capacity of 2.5 MW could generate
5.48GWh of renewable electricity per year
(based on a capacity factor of 25% – Note
that across the entire UK for onshore wind
the five year average capacity factor (2008–
2012) is 25.9 % (Table 6.5 from the July 2013
DUKES update available here:
https://www.gov.uk/government/publicatio
ns/renewable-sources-of-energy-chapter-6-
digest-of-united-kingdom-energy-statistics-
dukes). These figures are derived as follows
in the following example (using a 25%
capacity factor): 2,500kW (1 x 2.5MW
turbine) × 8,760 hours/year × 0.25 (capacity
factor) = 5,475,000kWh. Based on the
4,266kWh household figure and the
predicted electricity generation it is
estimated that the yearly output from the
wind turbine will be equivalent to the
approximate domestic electricity needs of
1,280 average households in Britain (e.g.
5,475,000÷ 4266 = 1,280). In September
2008 the Advertising Standards Authority
endorsed a figure of 430gCO2/kWh based
on the assumption that the energy
generated by the wind turbines displaces
Combined Cycle Gas Turbines and an
average mix generation
(430gCO2/kWh). On this basis and on
the assumption that the wind
turbine’s annual output is 5.48GWh
a wind energy development of this
scale is expected to displace 2,350
tonnes of CO2
The Development Site Location Plan (Figure 1.1 of
the ES) and Proposed Wind Energy Development
Layout (Figure 1.2a of the ES) are reproduced at the
end of this NTS along with a diagram of a typical
wind turbine structure (Figure 4.1 of the ES) which is
for a 2.5MW – 3MW machine with a 130m tip
height. This is the maximum overall height (to
vertical blade tip) of the turbine to be installed.
It is important to note that the works comprising the
electrical connection to the local distribution
network are not part of this planning application and
any consents required for these works will be
undertaken by the District Network Operator (DNO)
UK Power Networks. Negotiations are on-going
between the applicant and UK Power Networks to
confirm the exact method of connection to the local
distribution network. It is currently anticipated that
a connection will be made at the 11kV Tattingstone
Sub-station approximately 2.5km south of the
Development Site. The off-site grid connection is
anticipated to follow The Street south-east on to the
A137 (as shown in Figure 1.2b of the ES) where it
would head south-west following West Horse Hill
road and Coxhall road before reaching the sub-
station. At this stage it is not envisaged that any new
overhead line will be required to connect the turbine
to the local electricity network and therefore a
separate consent under Section 37 of the Electricity
Act is not anticipated.
The Development Site is centred on OS grid
reference 613939E 240345N and is comprised of
agricultural land. Furthermore the land on and
surrounding which the turbine is proposed to be
located is already subject to a consent for gravel
extraction and, therefore, already approved for
development. Because these two activities can
effectively co-exist this provides a way to optimise
the use of the developed land without impact on
further undeveloped land.
The Great Eastern Main Line railway runs south-west
to north-east forming the north-eastern boundary for
the Development Site. It is bounded by The Street and
Wherstead Wood to the south-west and agricultural
land in all other directions with Jimmy’s Farm (a
working farm and local tourist attraction) located to
the east at Pannington Hall. Pannington Hall cottage,
an occupied private residence, is located
approximately 450m to the south-east of the
Development Site boundary. Hill Covert Woodland is
located 500m north-east of the Development Site
boundary beyond Jimmy’s Farm. All other residential
properties are more than 700m from the proposed
wind turbine.
Existing topographical information indicated on the
Ordnance Survey map confirms that elevation of the
Development Site varies from 40m AOD in the south-
west to 35m AOD in the north-eastern corner.
Elevations fall to ~20m AOD in the easternmost corner
and alongside the railway line running into Ipswich.
There are no watercourses present within the
Development Site boundary. However, as described in
Chapter 13 paragraph 13.3.5, a field ditch was
identified along the south-western boundary of the
Development Site the location of which is shown on
Figure 13.1.
The A14 trunk road runs north-west to south-east
approximately 1km north-east of the Development
Site Boundary and the nearest village, Belstead, is
located approximately 900m to the north-west of the
proposed turbine.
Thorington Hall and Thorington Hall Cottage are
situated approximately 600m north-east of the
Development Site boundary. Both properties are
served by a private access track along which there is a
public right of way (a footpath and a bridleway) which
runs north-east to the south-west through the original
development area and linking to the public highway to
the north and south.
05
A residential housing estate which forms part of the
extreme south-western limits of the city of Ipswich is
present more than 1,200m from the wind turbine on
the northern side of the A14.
A number of Public Rights of Way traverse the
Original Development Area the key routes being FP31
and FP34 which cross the development site in an
east-west direction and FP33 which runs north-south
through the centre of the Original Development
Area. No Public Rights of Way are present within the
Development site boundary. However FP41 runs
approximately 100m to the north-east.
Environmental Impact Assessment (EIA)
EIA is a process that collects information about
potential environmental effects of a Proposed
Development and evaluates and presents this
information in a way that both assists consultation
and enables decision-makers to take account of these
effects when determining whether or not a project
should proceed. If the project does proceed the EIA
also helps identify any mitigation measures or
controls over the construction or operation that
might be required. The content and scope of the EIA
was agreed through consultation with Babergh
District Council following issue of their Scoping
Opinion in September 2011.
The EIA has identified the likely effects of the
Proposed Development on the environment and an
assessment has been made as to whether any of
these could be significant. In general terms
establishing whether an identified effect is significant
is determined by the importance of the receptor (e.g.
a particular listed building, ecological designated site
or landscape character area) and the magnitude of
change that will occur as a result of the construction,
operation and de-commissioning of the turbine
which, in turn, establishes the significance of effect.
Chapter 2 of the ES sets out the EIA methodology
employed in more detail.
A number of mitigation measures to reduce potentially
significant effects have been incorporated into the
design of the Proposed Development. Additional
measures are set out in a proposed Environmental
Management Plan (EMP) (Chapter 15 of the ES) to be
implemented during the construction and operation of
the wind turbine.
The Environmental Statement (ES) reports the findings
of the EIA which has been prepared in accordance with
The Town and Country Planning (Environmental Impact
Assessment) Regulations 2011. The ES comprises this
NTS and three volumes: Volume 1 – Written Statement,
Volume 2 – Figures and Volume 3 – Appendices.
The assessment of effects has been undertaken in an
impartial manner with the findings presented
systematically in the ES which will be used by Babergh
District Council to help inform its decision about
whether or not the Proposed Development should be
allowed to proceed.
Consultation
A vital aspect of the EIA process is consultation both to
agree which environmental topics need most attention
(scope of the EIA and methodologies to be adopted in
assessing likely effects) and to understand public
perception of the Proposed Development in order to
help inform the design process. Consultation with
statutory and non-statutory bodies was undertaken
through a formal scoping exercise with Babergh District
Council in September 2011. In addition there has been
continued dialogue with relevant statutory and non-
statutory consultees both before and after the Scoping
Opinion (setting out the environmental topics to be
considered further) was received from Babergh District
Council. The full list of consultees is set out in Chapter
2 of the ES and includes amongst others: Natural
England, English Heritage, Environment Agency, RSPB,
Suffolk County Council Highways, Suffolk County
Council Ecologist, Suffolk Wildlife Trust, Suffolk County
Council Archaeologist and Suffolk Coast and Heaths
AONB Partnership.

PfR’s projects enter the public domain at the very
early stages of development before any of the
detailed environmental work has been carried out.
This project first entered the public domain in March
2011 and evolved over time from a three-turbine
proposal to a single turbine project. Throughout the
lead up to the submission of this planning
application PfR has used a variety of communication
methods to keep local communities and other
stakeholders informed and to encourage them to
engage in the development process. These included
holding public exhibitions, wind farm visits,
producing periodic written correspondence and e-
mails to keep stakeholders informed, holding
community surgeries at various intervals throughout
the development process, providing a dedicated
website, giving presentations to interested parties
and attending house visits to nearest neighbours of
the proposed development. PfR’s consultation
events were advertised extensively with a series of
project newsletters, press releases and local radio
interviews. The following table summarises the key
events in the pre-application consultation:
March 2011 - Project-specific website launched
23rd March 2011 - Public Exhibition (Belstead
Village Hall)
14th July 2011 - Community Surgery (Belstead
Village Hall) & Site Walkover
September 2011 - Jimmy’s Farm Opinion Survey
Photomontage and Information Display
1st November 2011 - Community Surgery
(Belstead Village Hall) and walk up to the
recently installed wind monitoring mast
29th and 30th May 2012 - Wind Farm Visit with
presentation on wind energy
28th January 2013 - Community Surgery
(Pinewood, Belstead Brook Hotel)
29th January 2013 - Community Surgery
(Belstead Village Hall)
26th September 2013 - Single Turbine Proposal
Announced
The specific details of these communication methods
and results are outlined in the Statement of
Community Involvement. Furthermore the
Statement of Community Involvement clearly
demonstrates that PfR has listened and responded to
the concerns of local people by the evident evolution
of the project which has been revised from a three-
turbine proposal initially to a two-turbine and finally
a single turbine proposal.
Environmental Effects
The scoping exercise identified a range of potential
environmental effects that could arise as a result of
the development (which was a scheme of three
turbines at that time). These potential effects were
subject to detailed assessments using methodologies
specific to the relevant environmental topic. Those
topics considered in the EIA and presented in this ES
are listed as follows:
Climate Change Mitigation and Other
Atmospheric Emissions - Chapter 6;
Traffic and Transport – Chapter 7;
Noise – Chapter 8;
Landscape and Visual Impact – Chapter 9;
Cultural Heritage– Chapter 10;
Ecology – Chapter 11;
Ornithology – Chapter 12;
Hydrology – Chapter 13; and
Shadow Flicker – Chapter 14.
The following sections provide a brief, non-technical
summary of the main findings of the EIA split by
environmental topic. These findings are described in
detail within the individual environmental topic
chapters of the ES.
07
The Environmental Statement
The ES, which accompanies the planning
application to Babergh District Council, provides
detail of the assessment of identified significant
environmental effects resulting from the
construction, operation and de-commissioning
of the Proposed Development. The following
sections provide a brief, non-technical summary
of the main findings of the EIA which are
described in detail within the individual chapters
of the full ES.
Climate Change Mitigation and Other
Atmospheric Emissions– Chapter 6
The assessment of the effects on climate change
included calculating the expected renewable
electricity that would be produced by the
Proposed Development. The assessment
calculated that the Proposed Development could
annually generate 5.48GWh of renewable
electricity per year. This is equivalent to the
amount of electricity used annually by 1,280
average households and avoids 2,350 tonnes of
CO2 equivalent emissions per year1. Maximising
the renewable energy potential of the
Development Site will result in a positive effect
on climate change although it is not considered
appropriate to assign any level of significance to
this effect.
There is the potential for an increase in dust
during construction of the Proposed
Development due to earthworks and traffic
movement. The assessment comprised a desk-
based study to identify potential receptors
affected by dust emissions. It concluded that
the embedded mitigation measures, in line with
existing policy guidance and environmental
legislation, will reduce the risk of any dust
nuisance occurring at adjacent residential
properties during construction.
Traffic and Transport – Chapter 7
The Traffic and Transport element of the EIA has
considered the environmental effects associated
with abnormal load and HGV traffic movements
that will occur during the construction period. The
construction traffic is proposed to route to the
Development Site from the A14, the A137 and The
Street. It has been assumed that the turbine
nacelles and blades, as well as transformers, will be
shipped to the Port of Felixstowe and will be
delivered to the Development Site by road on
abnormal load transporters. The methodology
used for the assessment is based on the Institute of
Environmental Management and Assessment
(IEMA) guidance document entitled ‘Guidelines for
Environmental Assessment of Road Traffic’. The
purpose of this guidance is to provide a systematic
framework for the appraisal of environmental
effects as a result of traffic associated with a
development proposal.
The maximum traffic effects associated with the
whole development are predicted to occur during
turbine foundation concrete pouring during which
there would be 75 daily HGV movements over a
two-day period in the third month of construction.
During the remainder of the six-month
construction period the maximum traffic
movement generated by the development would
be 11 HGVs in the first month in addition to the 20
staff trips at the beginning and end of the day.
The traffic and transport assessment has identified
that the potential environmental effects of driver
delay and accidents and safety will be minimal and
‘not significant’ as the duration of effects is limited.
In addition the implementation of a Traffic
Management Plan (TMP) will manage the effects of
the development construction.
08
The TMP which will be agreed with Babergh
District Council prior to construction
commencement will detail measures aimed at
minimising adverse environmental effects
associated with traffic and transport during
construction. The TMP is expected to include
details on car parking, measures to encourage
multi-occupancy of vehicles bringing construction
personnel to site, temporary road signage
requirements, off-loading proposals, construction
traffic routing and timing of deliveries.
During the operation of the wind turbine a low
level of light vehicle traffic for maintenance is
expected with occasional requirements for larger
vehicles/plant for component
maintenance/replacement. Therefore the effects
on the local traffic numbers are not significant.
De-commissioning of the wind turbine is likely to
require less vehicle traffic than during
construction as delivery of some materials is not
required. The effects on local traffic numbers are
therefore likely to not be significant.
Noise – Chapter 8
Hoare Lea Acoustics (HLA) were commissioned by
Partnership for Renewables (PfR) to undertake a
noise impact assessment for the construction and
operation of the Proposed Development.
Noise will be emitted by equipment and vehicles
used during the construction and de-
commissioning of the wind energy development
and by the wind turbine itself during operation.
The level of noise emitted by the sources and the
distance from those sources to the receiver
locations are the main factors determining levels
of noise at receptor locations resulting from the
development.
Construction Noise
Construction noise has been assessed by a desk-
based study of potential representative
construction programme and by assuming the wind
energy development is constructed using standard
and common methods. Noise levels have been
calculated for receiver locations closest to the
areas of work and compared with guideline and
baseline values. Construction noise, by its very
nature, tends to be temporary and highly variable
and, therefore, much less likely to cause adverse
effects. Various mitigation methods have been
proposed to reduce the effects of construction
noise the most important of these being
restrictions of hours for heavy goods vehicle
deliveries and activities that may give rise to
audible noise at the surrounding properties to
08:00 to 18:00 Monday to Friday and 08:00 to
13:00 on Saturdays. It is concluded that noise
generated through construction activities will have
a negligible effect.
De-commissioning is likely to result in less noise
than during construction of the proposed
development. The construction phase has been
considered to have negligible noise effects;
therefore de-commissioning will, in the worst case,
also have negligible noise effects.
Operational Noise
Operational wind turbines emit noise from the
rotating blades as they pass through the air. This
noise can sometimes be described as having a
regular ‘swish’. The amount of noise emitted tends
to vary depending on the wind speed. When there
is little wind the turbine rotors will turn slowly and
produce lower noise levels than during high winds
when the turbine reaches its maximum output and
maximum rotational speed. Background noise
levels at nearby properties will also change with
wind speed increasing in level as wind speeds rise
due to wind in trees and around buildings, etc.
09
Noise levels from operation of the proposed wind
turbine have been predicted for those locations
around the development site most likely to be
affected by noise. Surveys have been carried out to
establish existing baseline noise levels at a
representative number of these properties. Noise
limits have been derived from data about the
existing noise environment following the method
stipulated in national planning guidance. Predicted
operational noise levels have been compared to the
limit values to demonstrate that a wind turbine of
the type and size which would be installed can
operate within the limits so derived. It is concluded
therefore that operational noise levels from the
wind energy development will be within levels
deemed, by national guidance, to be acceptable for
wind energy schemes.
Landscape and Visual – Chapter 9
The assessment has considered the potential for
significant landscape and visual effects to arise as a
result of the construction and operation of the
proposed turbine. Landscape effects may include
changes to the landscape elements and patterns
within the development site, changes to landscape
character and effects upon nationally and locally
designated landscapes.
The landscape assessment considered the potential
for effects on three nationally designated
landscapes (the Suffolk Coast and Heaths and
Dedham Vale Areas of Outstanding Natural Beauty
and the Suffolk Heritage Coast), six locally
designated Special Landscape Areas and sixteen
landscape character types (as defined by the Suffolk
and Essex Landscape Character Assessments). It
concluded that there would be no significant effects
upon any nationally or locally designated
landscapes and that there would be significant
landscape effects to only the two landscape
character types closest to the development site:
• The western and central parts of LCT B – Ancient
Estate Farmlands; and
• The Belstead Brook Valley and northern Alton Water
parts of LCT I – Rolling Estate Farmlands.
The landscape assessment therefore concluded that the
proposed development is appropriate to the capacity of
the receiving landscape and is acceptable in landscape
terms.
The assessment of visual effects is concerned with
changes to views available to people and to their visual
amenity. These include views from individual residential
properties, settlements, transportation routes and
outdoor recreational facilities such as public rights of
way, open access areas, country parks, or golf courses.
The visual assessment considered the potential for
significant levels of visual effect to be sustained by one
hundred and sixty-eight separate visual receptors.
It is widely recognised that wind energy development
will inevitably result in some significant visual effects due
to the height and movement of turbines. However the
number of significant visual effects assessed as certain or
likely to arise as a result of the introduction of the
Pannington Farm Wind Turbine is relatively limited being
concentrated upon a proportion of residents in
properties within 1.2 km and users of the parts of the
public rights of way network within 3km.
The assessment effects on the views of residents within
1.2km concluded that the proposed development may
result in significant effects on the views available from
twenty-two of the forty individual residential properties
or groups of properties within this area as might
reasonably be expected for any wind turbine
development within this distance. If the groupings used
in the assessment are disaggregated this represents a
maximum of forty-eight individual properties out of the
total of eighty-eight within 1.2km.
09 10 10
It should be borne in mind that this figure is
likely to overstate the actual number of
properties at which significant effects on views
might be sustained as the group assessments
were based on the highest level of effect
sustained by any one property within a group.
The distribution of potentially significantly
affected properties in relation to the proposed
turbine would be:
• one property to the north-east
(Thorington Hall);
• three properties to the south-east
(Pannington Hall, Pannington Hall Cottage
and Bluegates Farm);
• two properties to the west (36 & 37
Bentley Lane); and
• forty-two properties within Belstead (Pine
Lodge, Belstead Group 2, Garden House,
Belstead Groups 3 & 4, Windmill Ridge,
Belstead Groups 5, 6 & 8, Cropley Grove,
The Bogan, Strathlea and Belstead Groups
9, 10, 14 & 15).
Of these properties thirty-two may sustain a
‘moderate’ level of effect and sixteen a
‘substantial’ level of effect. No properties are
assessed as being likely to sustain the highest
‘very substantial’ level of effect.
With regard to other settlements the
assessment concludes that no other residential
visual receptors would be likely to sustain
significant adverse visual effects. The
assessment also concludes that no recreational
visual receptors using country parks, visiting
parks and gardens, at golf clubs, at caravan
parks, walking regional trails or cycling regional
or national cycle routes would sustain
significant adverse visual effects.
Recreational visual receptors using sections of any
of the PRoWs that are entirely or partly located
within the development site itself would sustain
significant adverse effects due to the proximity and
therefore the scale of the turbine augmented in
some instances by the presence of ground level
components. The assessment also included
recreational visual receptors using PRoWs within
3km of the proposed turbine grouped together as
seven PRoW networks (A – G). It was concluded
that significant adverse visual effects would be
experienced by users of some of the PRoWs in
three of these seven groups of PRoWs: those to the
north, west and east of the development site.
Detailed consideration has also been given to the
potential for the residents at the closest properties
to sustain unacceptable levels of effects upon their
residential visual amenity. Although residents at
forty-eight properties within 1.2km could sustain
significant adverse visual effects none would
sustain the highest ‘very substantial’ level of effect
and when the wider criteria employed in
determining residential visual amenity are applied
none of the residents at these properties would
sustain unacceptable adverse effects upon their
residential visual amenity. A key factor in this is
that the proposed wind energy development
consists of a single turbine avoiding any scope for
residents in any property to have a sense that they
are surrounded by turbines. All properties would
be separated from the proposed turbine by at least
540m (at least 700m with the exception of
Pannington Hall and Pannington Hall Cottage). In
conjunction with the fact that there would always
be at least some intervening vegetation to help to
provide the requisite sense of separation the scope
for the turbine to seem overbearing is effectively
removed.
11
The cumulative assessment concluded that the
separation distances between the proposed
Pannington Farm Wind Turbine and the limited
number of other onshore and offshore wind
farms included within the cumulative assessment
are sufficiently large to ensure that there would
be no potential for significant cumulative
landscape or visual effects to arise.
Cultural Heritage – Chapter 10
The potential for archaeological remains within
the Development Site has been suggested by
artefact finds and areas of interest in the
surrounding area which are recorded on the
Suffolk Historic Environment Record. A
geophysical survey was undertaken at an early
stage in the development design process which
covered key areas of the Development Site and a
wider surrounding area (the original
development area). This identified the possible
course of a palaeochannel within the
Development Site. The survey did not indicate
any archaeological remains within the
Development Site but did confirm the presence of
some recorded features in the vicinity of the
Development Site. No direct effects on
archaeological remains have therefore been
identified.
There is some potential that further
archaeological remains, which have not currently
been identified, could be encountered during
construction. The possibility for this can be
addressed by trial trench archaeological
evaluation following determination of the
planning application and prior to construction
works commencing and which could be made a
condition of any planning permission
There is the possibility for the construction
methodology of some elements of the scheme,
such as access tracks, to be adapted to preserve
any important remains thus identified. There is
also some potential for the micro-siting of
elements of the scheme by up to 50m in order to
avoid any important archaeological remains
identified subject to other constraints. However
the lack of identified archaeological remains and
the small footprint of the Proposed Development
is such that it is expected that any remains which
are affected can be excavated and recorded and
there will be no significant effects on heritage
assets within the Development Site. The
potential for any effect on archaeological remains
as a result of the Proposed Development should
also be seen in the context of an existing
permission for the extraction of sand and gravel
from land including the Development Site which
would, in any case, be expected to completely
remove any remains of archaeological (or
palaeoarchaeological; palaeoenvironmental)
interest which may be present.
There are a number of nationally designated
monuments and buildings in the area surrounding
the Proposed Development. However there are
few monuments with upstanding remains whose
settings contribute to their heritage significance
and would be likely to be affected. Listed
buildings in the vicinity of the Development Site
tend to occupy relatively sheltered locations and
few have outward views which are important to
their heritage significance or which are likely to
be affected where they do occur. Listed buildings
within the vicinity of the Development Site also
tend to be well screened by mature trees and
hedgerows which predominate in this area.
13 12
It is considered that the effect of the
operational wind turbine on the setting of
those assets identified will result in no
significant effects. Moreover any effects are
entirely reversible on the de-commissioning of
the development. Given the 25 year term of
the consent applied for this is a relatively small
length of time in view of the longevity of
buildings and particularly of monuments in the
vicinity of the Development Site and changes
wrought on the landscape during this time.
It is judged that all effects on heritage assets
arising from the Proposed Development fall
considerably short of substantial harm in
terms of the National Planning Policy
Framework (NPPF) and must be weighed
against the wider benefits associated with the
proposal accordingly.
Ecology – Chapter 11
The biodiversity baseline was established by
obtaining data relating to statutory and non-
statutory biodiversity sites, priority habitats
and species and legally protected and
controlled species within the zone of influence
of the Proposed Development. Surveys
undertaken included an extended phase 1
habitat survey, hedgerow surveys, surveys for
protected species (badgers, bats, dormouse,
great crested newts and reptiles) and legally
controlled plants. The effects of the Proposed
Development on the following biodiversity
receptors were considered in the detailed
assessment: Spinney Wood/Wherstead Wood
County Wildlife Site, hedgerows, badger, bats,
dormouse, reptiles and great crested newt.
Initial assessment of effects on these receptors
was based on the incorporation of a number of
mitigation measures into the scheme design.
These include: dust suppression measures,
retention of the highest-value habitats on the
Development Site, a minimum distance of 50m
between turbine blade tips and the nearest
point of woodland and hedgerows to reduce
the likelihood of bat collisions with rotating
turbine blades, a Construction Environmental
Management Plan (CEMP) and accompanying
method statements in relation to the protection
of legally protected species, dust suppression
measures, a site speed limit of 10mph to reduce
the risk of collisions with fauna including
badgers, operational noise limits to be set
relative to the background noise levels and
siting of the turbine and associated
infrastructure away from any known badger
setts.
No significant effects were predicted for any
ecological receptors other than hedgerows.
Not significant, but greater than negligible,
effects were predicted for some bat species as a
result of potential turbine collisions and on
hedgerows and dormice as a result of the
removal and/or trimming back of section of
hedgerow to facilitate the access road.
Furthermore the required visibility splays at the
site entrance have been designed based on
data relating to the actual speed at which
vehicles travel along the road as opposed to the
road speed limit of 60mph. This minimises the
requirements for hedgerow removal and
trimming to reduce effects on the hedgerow
resource and dormice habitat.
16 04 13
Further mitigation and monitoring measures were
proposed and will be incorporated into the
Environmental Management Plan namely:
Minimum two-for-one replacement of
hedgerows to be removed or trimmed back with
new planting;
Additional measures to improve habitat
suitability for dormouse foraging and nesting
through sensitive habitat management;
Maintenance of short vegetation/arable crop
around the turbine to discourage bat foraging
and therefore further reduce the risk of
collisions; and
A monitoring scheme to assess the effectiveness
of the mitigation proposed for bats.
No significant residual effects are predicted as a
result of constructing and operating the Proposed
Development. No significant in-combination effects
of the present scheme and other developments
(including the gravel extraction scheme and the off-
site grid connection) are predicted.
Ornithology – Chapter 12
Twelve months of bird surveys were carried out at
the Development Site between April 2011 and March
2012 comprising vantage point watches, winter
walkover surveys and breeding bird territory
mapping surveys.
The breeding bird community observed on site and in
the wider survey area comprised a range of common
and widespread farmland species including skylark,
linnet, chaffinch, whitethroat and yellowhammer.
The winter bird community was found to be typical
of similar arable farmland habitats within the wider
area. Those species most regularly occurring on-site
and within the wider survey area included wood
pigeon, black-headed gull, herring gull, chaffinch,
starling and skylark. Those species most regularly
recorded along hedgerow, tree lines and scrub
habitats in the wider area included fieldfare and
redwing.
Flight activity of focal species was limited to a
number of kestrel flights throughout the survey
season and very low numbers of lapwing and pink-
footed goose flights during the winter. The risk of
collision is predicted to be negligible for all three
species.
Active crops will however be maintained within
and around the turbine location in order to avoid
the presence of rough grassland and fringe
habitats which are important for kestrel foraging
further reducing collision risk.
No significant residual effects are predicted as a
result of constructing and operating the Proposed
Development. No significant in-combination
effects of the present scheme and other
developments (including the gravel extraction
scheme and the off-site grid connection) are
predicted.
Hydrology – Chapter 13
An assessment was carried out to provide an
understanding of the hydrological, hydrogeological
and ground conditions baseline for the
Development Site. In summary a desk-based study
identified several receptors that have the potential
to be affected by the development resulting from a
change in water quality or flood risk not only by
the construction phase but also by the change in
land use associated with the Proposed
Development. The associated impacts of the
Proposed Development on the water environment
including those associated with flood risk and
ground conditions were considered. However, in
line with existing policy guidance and
environmental legislation, mitigation measures in
the form of pollution prevention and drainage
control will be put in place to ensure there will be
no residual significant effects on hydrological or
hydrogeological receptors arising from the
development.

Shadow Flicker – Chapter 14
Under certain combinations of geographical
position, time of day and time of year and weather
conditions the sun may pass behind the rotor of a
wind turbine and cast a shadow on to nearby
properties. When the blades rotate the shadow
moves and, where the shadow is cast over an
aperture such as a window or an open door, the
light intensity within the room may appear to
increase and decrease as the shadow passes
repeatedly and this is known as ‘shadow flicker’.
Experience has shown that shadow flicker has the
potential to cause annoyance to occupants of
affected properties under certain circumstances.
The National Policy Statement (NPS) for
Renewable Energy Infrastructure (EN-3) (DECC,
2011) discusses the planning and development of
nationally significant renewable energy schemes
across England. This guidance is also of relevance
to smaller schemes as emphasised by Paragraph 3
of the NPPF which states that the NPSs form part
of the overall planning framework and are a
material consideration in decisions on planning
applications. Reference is made to shadow flicker
in NPS EN-3 which states that “Where wind
turbines have been proposed within 10 rotor
diameters of an existing occupied building, a
shadow flicker assessment should be carried out
by the applicant”. It also states that there is
“unlikely to be a significant impact at distances
greater than ten rotor diameters from a turbine”.
A study has therefore been carried out to identify
whether shadow flicker is likely to occur at
residential and selected non-residential properties
in the vicinity of the proposed wind turbine
location (a study area of 1,050m has been used to
reflect a 100m rotor diameter with an addition of
50m to allow for micro-siting of the turbine).
Modelling has been carried out to predict the
duration of any shadow flicker effects and the
times of day and year when it could occur. The
effect of shadow flicker on nearby residential and
selected non-residential properties (e.g. village
hall) is quantified by calculating the predicted
theoretical maximum number of hours per year
that shadow flicker may occur at a dwelling from
the relative position of the turbine, the geometry
of the wind turbine and the latitude of the
Proposed Development. The model does not take
into account the screening effect of nearby
vegetation or neighbouring buildings. There are
sixty-four potential receptors within 1,050m of the
proposed wind turbine; the potential receptors
have been grouped by location and, where
necessary, average window parameters have been
used in the model. In summary the assessment
has shown that there is the possibility of eleven
individual receptors predicted to experience a
significant theoretical level of shadow flicker effect
prior to accounting for real weather conditions and
the application of mitigation measures.
In practice the magnitude of shadow flicker effect
will be less than that calculated due to a number of
factors which are not considered in the model
including the presence of obstacles such as trees
and buildings, times when the wind turbine is not
turning and the orientation of the rotor relative to
the windows of nearby properties due to wind
direction. The base model used in this assessment
also does not account for cloud cover which may
prevent shadow flicker from occurring. Historical
data for Wattisham met office, located 15km from
the Proposed Development, indicate that 38% of
daylight hours are considered sunshine hours.
Therefore as part of this shadow flicker assessment
the likely amount of shadow flicker effect has in
addition been calculated based on this average
number of sunshine hours.
15
The proposed turbine will incorporate an automatic turbine control system which can be programmed
and activated to fully mitigate and avoid any shadow flicker effect that is predicted to occur once
operational. No significant residual shadow flicker effects are therefore anticipated.
