1 INTRODUCTION
1.1 DEVELOPMENT BACKGROUND
SSE is proposing to construct a new CCGT power station (Keadby II) to the
west of the existing Keadby I Power Station. Keadby II is currently the subject
of a section 36c application to vary the original consent. Once Keadby II is
constructed it will need to be connected to the National Grid (NG) electricity
transmission system. Keadby I has an existing connection to the NG
electricity transmission system by means of two separate overhead lines and
associated transmission towers, which connect with the main Keadby 400kV
NG substation (located to the north-west of the Keadby I and II sites).
One of the existing Keadby I overhead lines is connected to the southeast
corner of the NG substation site. There are a number of other existing
overhead lines connecting to the NG substation to the west of this
connection. The presence of these overhead lines to the west constrains the
ability for Keadby II to connect to the NG substation. In order to overcome this
constraint the following is proposed (more detail on the Proposed
Development is provided in Section 2):
Keadby I: The existing Keadby I connection with the NG substation
(connecting to the southeast of the substation) will be replaced by a new
overhead line. This will run from the existing transmission tower to the
north of the Keadby I site to a new tower, located close to the southeast
corner of the substation, before connecting into the substation via a spare
bay. The new tower is located approximately 95 metres to the east of the
existing tower, and the approximate length of the replacement line will be
285 metres.
Keadby II: A new overhead line will be installed, running from the
Keadby II site to the existing transmission tower close to the southeast
corner of the NG substation (currently used for the existing Keadby I
connection). This will connect into the NG substation via the existing
Keadby I bay. The approximate length of the new line will be 240 metres.
1.1 REGULATORY CONTEXT
The Electricity Act 1989
Section 37 ‘Consent required for overhead lines’, sub-section (1) of the
Electricity Act 1989 (the ‘1989 Act’) provides that:
“(1) Subject to [subsections (1A) to (2)] below, an electric line shall not be
installed or kept above ground except in accordance with a consent granted
by the Secretary of State.”
An ‘electric line’ is defined at section 64, sub-section 1 of the 1989 Act as:
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
2
“electric line” means any line which is used for carrying electricity for any
purpose and includes, unless the context otherwise requires-
(a) any support for any such line, that is to say, any structure, pole or other
thing in, on, by or from which any such line is or may be supported, carried or
suspended;
(b) any apparatus connected to any such line for the purpose of carrying
electricity; and
(c ) any wire, cable, tube, pipe or other similar thing (including its casing or
coating) which surrounds or supports, or is surrounded or supported by, or is
installed in close proximity to, or is supported, carried or suspended in
associated within, any such line;…”
The proposed overhead lines clearly fall within the definition of an ‘electric
line’, and unless an exception applies, consent will be required under section
37 of the 1989 Act. In addition, planning permission will be required. On
granting a consent under section 37, the Secretary of State may give a
direction that planning permission be deemed to be granted.
The DWD Planning Statement submitted in support of the Section 37
Application provides more information on the regulatory context for the project.
1.2 PURPOSE OF THIS REPORT
This report has been prepared to support separate applications for planning
consent that are being made to DECC in respect of the proposed Keadby I
and Keadby II overhead lines. It provides the information on the nature and
purpose of the Proposed Development and of its possible effects on the
environment.

2 PROJECT DESCRIPTION
2.1 INTRODUCTION
The Proposed Development will involve realignment of one of Keadby I’s
existing overhead lines to allow connection of the Keadby II power station to
the main Keadby 400kV NG substation.
The Keadby I connection will involve the following main activities:
1. Construction of a new transmission tower approximately 95 m to the east
of the existing transmission tower. The planned location of the new tower
is out with the SSE Keadby site, just to the south of the substation.
2. Realignment of the existing Keadby I power line to connect it to the new
tower, and thereafter via a new section of overhead line into a spare bay
within the substation. The new route of the power line will be slightly to the
east (at most 95 m) of the existing line’s route. Both the existing and new
route pass over some land that is not within the SSE Keadby site.
The Keadby II connection will involve construction of a new section of
overhead power line from the Keadby II power station to the existing
transmission tower (currently used for the Keadby I connection). Thereafter
the connection will utilise the existing section of overhead line from the tower
into the existing bay currently utilised for Keadby I.
The new tower will have a 50 m wide easement to allow for construction and
there will be a 30 m wide wayleave along the full length of each of the two
routes.
An overview of the existing and proposed layout for the overhead lines is
presented in Figure 2.1. Figure 2.2 presents a three dimensional view of the
Proposed Development, with new power transmission infrastructure and the
routes of the new and realigned overhead lines highlighted in blue.

2.2 DESIGN
2.2.1 The Tower
The new transmission tower will be of lattice steel construction and will be of
the tension type which allows deviation of the overhead line as it passes
through the tower. The tower will have an approximate height of 44 m. The
existing towers that connect Keadby I to the substation are approximately
44.2 m high.
2.2.2 The Conductors
The new overhead line conductors will have a voltage of 400 kV. They will be
uninsulated and are likely to be of All Aluminium Alloy Construction (AAAC)
type. The overhead lines will have a minimum clearance of 9.2 m. This is the
same minimum clearance as the existing Keadby I connections.
The existing overhead line for Keadby I that is to be removed is 310 m long,
and the replacement line will be approximately 285 m in length. The
approximate length of the new line connecting Keadby II to the existing
transmission tower will be 240 m.
2.3 CONSTRUCTION ACTIVITIES
2.3.1 Overview
The construction of the overhead lines will be undertaken in five broad stages:
provision of temporary access and a working area for plant, equipment,
materials and workforce to access the tower site;
tower foundation installation;
tower erection;
installation of conductor and insulators on the new and existing towers
(conductor stringing); and
reinstatement of access and working areas to original condition
Construction hours will be agreed with the local planning authority. It is
proposed that working hours will be in line with those proposed for the Keadby
II development, as follows:
Monday to Friday: 07:00 to 19:00; and
Saturday: 08:00 to 14:00.
Pile driving for foundations and other noisy activities will be limited to the
following times:
Monday to Friday: 08:00 to 18:00; and
Saturday: 08:00 to 14:00.
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
7
The overall duration of works is expected to be approximately six to eight
weeks.
2.3.2 Access and Accommodation Work
This work will consist of installing temporary access to each of the working
sites to enable plant and materials to be taken to the tower and conductor
stringing locations without causing damage to the land or interfering with
existing infrastructure.
From a point of access from the Chapel Lane (accessed itself via the existing
dedicated SSE Keadby access road), aluminium trackway panels (or similar)
will be laid to form a temporary access track to the construction working areas.
For the tower foundation and tower erection work the sites will require a
temporary access track. For conductor stringing work a temporary access
track is less likely to be required. Suspension towers can be accessed using
specialist four wheel drive or tracked low ground bearing pressure vehicles.
However, should there be particularly bad ground conditions at the time of
construction work a temporary trackway may be installed.
All temporary access tracks will be removed on completion of construction
works, leaving no permanent damage or evidence of their installation.
2.3.3 Foundation Installation
The ground conditions at the proposed location for the new transmission tower
will determine if the foundation is either piled or a pyramid design.
A piled foundation design will require a piling rig on site to install piles to an
average depth of 20 m (depending on ground condition). Once the piles are
installed a concrete block will be cast at ground level to connect the piles to
the start of the tower steelwork.
A pyramid foundation design will require four excavations to house the start of
the tower legs. Typical dimensions for the four excavations are 4 m square by
5 m deep. Pyramid shape shuttering will be installed in the bottom of the
excavation, the concrete poured, and then the excavation back filled to bury
the pyramids leaving just the four legs of the tower protruding from the ground
by approximately 1 m. Typical material requirements for this type of
foundation design are 10 tonnes of reinforcement steel and 140 m3 of
concrete.
2.3.4 Tower Erection
The tower will typically consist of approximately 20 tonnes of steelwork bars.
These will be delivered to site on a low loader lorry, and then assembled on
the ground around three sides of the tower foundation in box sections of
approximately 10 m in height. The box sections will then be lifted into position
one on top of each other by a crane. The crane is typically located on the 4th
side of the tower on a temporary trackway at the side nearest the access road.
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
8
An area around the tower of approximately 50 m by 50 m will be required to
assemble the steelwork.
2.3.5 Conductor Stringing
When the tower has been built the overhead line can then be installed.
This will be undertaken using specialist conductor pulling machines that string
and tension the conductor between the connection points at each end and
across the tower.
The same process will be used to install the new overhead line section
between Keadby II and the existing transmission tower (currently used for
Keadby I).
2.4 ALTERNATIVES
As noted in Section 1.1, the proposals have been determined by the locations
of Keadby I, Keadby II and the NG substation, and the presence of other
overhead lines, all of which limit the routing options.
An alternative considered was the use of underground cables to connect
Keadby II to the NG substation. This option removes the requirement to re-
route the Keadby I connection and to build a new transmission tower.
However, laying an underground cable would require excavation of a trench
both within and out with the SSE Keadby site. As there is a high level of
existing surface and subsurface infrastructure within the area through which a
cable would likely be routed, in particular in the vicinity of the substation
boundary, this option was not considered feasible.
In addition to the above considerations a key environmental benefit of
underground cables, namely avoiding landscape and visual impact, would not
be delivered in the context of the project area.

3 RELEVANT PLANNING POLICY
3.1 INTRODUCTION
This section considers the energy and planning policy context for the
Proposed Development, including: the Government’s National Policy
Statements (‘NPSs’) for energy; the National Planning Policy Framework
(‘NPPF’); and the local development plan.
3.2 NATIONAL POLICY
3.2.1 National Policy Statements (‘NPSs’) for Energy
The energy NPSs are a material consideration in the Secretary of State’s
determination of the applications for section 37 consent (and deemed planning
permission) made in respect of the Proposed Development.
The NPSs that are considered to be of most direct relevance to the Proposed
Development are:
Overarching NPS for Energy (EN-1);
NPS for Fossil Fuel Electricity Generating Infrastructure (EN-2); and
NPS for Electricity Networks Infrastructure (EN-5).
3.2.2 National Planning Policy Framework (NPPF)
The NPPF came into effect in March 2012. It sets out the Government’s
planning policies for England and how they are expected to be applied. The
NPPF must be taken into account in plan making and is a material
consideration in planning decisions.
3.2.3 Planning Practice Guidance
In March 2014 the Department for Communities and Local Government
(DCLG) established its web resource which addresses a variety of topics by
way of Planning Practice Guidance (‘PPG’). These include air quality; climate
change; conserving and enhancing the historic environment; consultation and
pre-decision matters; design; environmental impact assessment; flood risk and
coastal change; health and wellbeing; land affected by contamination; land
stability; light pollution; natural environment; noise; planning obligations;
renewable and low carbon energy; travel plans, transport assessments and
statements in decision making; use of planning conditions; waste; and water
supply, wastewater and water quality.
3.2.4 North Lincolnshire Local Plan
The North Lincolnshire Local Plan (NLLP) is extant and is still used to make
planning decisions, though it is gradually being replaced by the North
Lincolnshire Local Development Framework. The plan was adopted in May
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
10
2003. The introduction explains that North Lincolnshire Council (NLC) was
established as a unitary authority on 1 April 1996, comprising the former
districts of Scunthorpe, Glanford and the Isle of Axholme part of Boothferry
which were previously part of the County of Humberside (paragraph 19).
Policy DS17 relates to Overhead Power Lines and High Powered Electrical
Installations. The policy states that the Council will seek to minimise the
environmental effects of proposals for overhead power lines of 132kV or
above and will not support such development where it would have a
detrimental effect on Special Protection Areas (SPA), Special Areas of
Conservation (SAC) and Ramsar sites; Sites of Special Scientific Interest
(SSSI) or other statutory nature conservation sites; conservation areas,
buildings of historic / archaeological interest; and existing committed or
allocated housing areas.
3.2.5 North Lincolnshire Core Strategy
The North Lincolnshire Local Development Framework Core Strategy was
adopted in June 2011. Policies that may of relevance to the Proposed
Development include the following.
Policy Title
CS1 Spatial Strategy for North Lincolnshire
CS2 Delivering More Sustainable Development
CS3 Development Limits
CS4 Creating a Renaissance in North Lincolnshire;
CS5 Delivering Quality Design in North Lincolnshire

4 ENVIRONMENTAL AND SOCIAL INFORMATION
The Proposed Development is situated to the northwest of the existing
Keadby I power station, located near to Keadby, Lincolnshire. Key features of
the environmental and social setting for the Proposed Development are shown
in Figure 4.1 and Figure 4.2.
4.1 LAND OWNERSHIP AND USAGE
The Proposed Development will be sited on land owned by SSE and the NG.
Land in the Proposed Development area was previously used for power
generation: it was the location for the Keadby coal-fired power station from the
1950s to the 1980s. The coal-fired power station was decommissioned in the
1980s, and since then part of the site has been used for the development of
the Keadby I gas-fired power station, while the remainder is effectively unused
land. The existing Keadby I power station is located to the southeast of the
Proposed Development. Power distribution infrastructure, including the NG
substation immediately to the north, and wind turbines are found across the
wider area. The Stainforth and Keadby canal and a main railway line are
located further to the south. Land use in the wider region is predominantly
agricultural.
The Proposed Development is located in an area of historical and current
industrial use, with no sensitive land uses within or close to the development
site that could be affected by the development. The development will not
result in loss of greenfield land. There will be no significant effects on land
use in the wider area or on sensitive land uses as a result of the Proposed
Development.
The re-routing of the Keadby I connection and connection of a new overhead
power line will facilitate the development of the Keadby II power station. This
development will have a positive impact on future energy generation. No
other planned land use in or around the location will be affected by the
Proposed Development. There will be no significant effects on future land use
in the wider area as a result of the Proposed Development.

4.2 LAND AND WATER
Previous site investigations within the SSE Keadby site have identified
elevated concentrations of some metals (chromium, lead) within soils. This is
assumed to be linked to historic industrial usage of the site. Baseline soil
concentrations of other metals investigated were typical of natural levels in
agricultural soils and fell well below guideline levels for commercial end use of
soil. Due to historic coal power production at the site, made ground at the site
may contain industrial waste materials and pulverised fuel ash.
There are no surface water bodies within the footprint of proposed works or
within the wider site: the closest watercourse is located to the south,
approximately 300 m from planned construction works. The River Trent
passes further to the east. Site investigations across the wider SSE Keadby
site have found shallow groundwater.
The Proposed Development will involve small scale construction works to
build a new transmission tower, including ground clearance and foundation
works. The footprint of this activity falls within an area of current and historic
industrial use. No groundworks will be required for the raising of the new or
the realigned overhead lines. Only small physical changes will occur during
construction, and will be confined to within and close to the SSE Keadby site,
with no changes to topography, land use or water bodies.
There will be minimal use of materials that are potential contaminants during
construction of the transmission tower and raising of the overhead lines.
Appropriate construction measures will be employed to ensure that pollutants
are not released to water or land. Adherence to Environment Agency
guidance and good construction site practices will ensure that no significant
effects on land or water resources will occur during construction.
As noted above, there is potential for contaminated soil to be present within
the construction site. Prior to construction of the transmission tower, soil
investigation works will be carried out at the location of any planned ground
disturbance. Contaminated soils uncovered during this process or during
construction will be isolated, removed and disposed of appropriately. If
necessary, consideration will also be given to the use of alternative piling
methods to prevent the spread of contamination. No groundworks will be
required for connection of the overhead power lines, and so there is no
potential for disturbance of contaminated soils during this activity.
The closest surface water body to the development is located approximately
300 m to the south of planned construction works. Shallow groundwater is
found in the area, but will not be affected by the relatively small scale and
localised construction works involved. As noted previously, appropriate
construction measures will be employed to ensure that pollutants are not
released to water or land. No significant effects on surface or groundwater
resources are likely due to the control measures in place.

4.3 ECOLOGY
Over time some semi-natural habitat has become established on disturbed
ground within the SSE Keadby site. Ecology survey and assessment work
carried out as part of the EIA for the Keadby II development indicates that
habitat within the area of Proposed Development is made up of bare ground,
semi-improved grassland, amenity grassland and small areas of scattered
scrub. The habitat types present in and around the construction area are
shown in Figure 4.3.
There are no designated sites within the footprint of the Proposed
Development. A non-statutory designated site (Keadby Power Station: Site of
Nature Conservation Importance) is located over 250 m to the south. This site
has been designated for its scrub and grassland habitat, supporting diverse
and varied flora.
The closest statutory designated site (Humber Estuary: SAC, Ramsar site and
SSSIs) is approximately 800 to 1,000 m from the development area at its
nearest point, where part of the tidal River Trent runs to the east of the SSE
Keadby site. The Humber Estuary is also designated as an SPA, but the
boundary of the SPA site is further (more than 10 km) from the Proposed
Development. Qualifying habitat features for the SAC include Atlantic salt
meadows, estuarine habitats, sandbanks, coastal lagoons and dunes, and
qualifying species include grey seal (Halichoerus grypus), river lamprey
(Lampetra fluviatilis) and sea lamprey (Petromyzon marinus). The site also
supports internationally important numbers of waterfowl in winter and
nationally important breeding bird populations in summer, which support its
Ramsar and SPA status. Bird species with nationally or internationally
important populations present within the Humber Estuary designated site are
listed in Table 4.1.

Many of the qualifying features described for the Humber Estuary site are
associated with coastal and estuarine habitats that are not present at the
closest point to the site in the upper reaches of the tidal River Trent.
Qualifying features that may be present in the tidal River Trent include river
lamprey and sea lamprey. In addition, some qualifying interest bird features of
the Humber Estuary SPA and Ramsar site may feed or roost in arable fields
surrounding the Keadby SSE site while on passage or over winter, including
golden plover, grey plover, lapwing, curlew, whimbrel and dark-bellied brent
geese. Given the level of development in the surrounding area, these fields
are not considered to represent an important feeding or roosting resource for
these qualifying species.
Protected species identified as potentially present in the surrounding area
include bats, water voles, amphibians and breeding birds. Some scattered
scrub is present within the construction work area, running alongside Chapel
Lane, and this could represent foraging habitat for birds or bats. This habitat
has a limited extent within the working area defined for the Proposed
Development, and is widely available in the wider area. None of the other
habitats within the development area support the protected species that may
be present in the area.
Given the nature of the planned construction and operational activities, and
the distance to designated sites, there are not expected to be effects from the
Proposed Development on either statutory or non-statutory sites. Appropriate
construction measures will be employed to ensure that pollutants are not
released to water or land, and no construction or operational activities are
likely to affect sensitive ecological areas situated outside of the Proposed
Development area or the ecological populations reliant upon them.
Due to the habitat requirements of the protected species identified above, they
are unlikely to be present within and around the construction works for the
Proposed Development at locations where they could experience impacts
from either construction or operational activities. The activities being
undertaken as part of the Proposed Development are not anticipated to
significantly affect any protected, important or sensitive species of fauna or
flora. As part of the construction management plan for the development,
activities will be conducted as far as possible outside of the bird breeding
season (reasonably being regarded as 1st April-31st July given the northern
location), to reduce the likelihood of disturbing species that may be present in
the wider area.
4.4 CULTURAL HERITAGE
A desk based study carried out as part of the EIA for the Keadby II
development identified the potential for archaeological remains to survive
within deposits in the area to the west of Chapel Lane (to the south and
southwest of the Proposed Development). No further areas of historic or
cultural importance have been identified within the area that could be directly
affected by the development. Given the proximity of the Proposed
Development to the NG substation to the north and to the Keadby I power
station, the construction area may have experienced previous ground
disturbance.
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
18
As part of the EIA for the Keadby II development, heritage assets within the
zone of potential visual influence of the proposed Keadby II power station
were identified. These included listed buildings in the surrounding area
(Keadby Bridge and the Rectory Lodge at Gunness), as well as a scheduled
monument (Keadby Lock) and a non-designated asset (Chapel Lane swing
bridge).
Construction of the new transmission tower will involve relatively minimal
ground works (either piling or excavation within a limited area), while
connection of the new and realigned overhead power lines will involve no
ground works. Prior to construction, site investigation work will be conducted
within planned locations of groundworks that will include an archaeological
watching brief. If evidence of buried archaeology is discovered, construction
work will be stopped while a plan for the preservation of the remains, if
required, is developed.
The Proposed Development will not be visible at the majority of the heritage
assets listed above, as they will be obscured by the presence of Keadby II, in
addition to existing buildings and industrial infrastructure. The Proposed
Development is closest to and may be visible from the non-designated Chapel
Lane swing bridge. However, in the context of the existing and proposed
infrastructure in the immediate and surrounding area, there will not be a
significant effect on the setting of this heritage asset from the development (as
illustrated in Figure 4.6).
4.5 LANDSCAPE
The Proposed Development is located within the Humberhead Levels National
Character Area (NCA). Local landscape types in the surrounding area include
flat farmland, industrial landscape, elevated wooded farmland and slopes,
urban areas and despoiled landscape. The immediate area of the Proposed
Development has an industrial character. Views within the wider area are
generally open and across flat farm land, but in the immediate area are
interrupted by large infrastructural elements such as power stations, electricity
pylons and wind turbines. No landscape areas or features of high value have
been identified in the immediate vicinity of the Proposed Development.
Figure 4.4, Figure 4.5 and Figure 4.6 present photographs of existing views of
the Proposed Development area, alongside photomontages of the view as it
will appear if both Keadby II (single shaft option) and the Proposed
Development are constructed. As the Keadby I overhead line already exists,
and will simply be realigned, the new transmission tower and new overhead
line from Keadby II will be the only new potential sources of visual impact from
the Proposed Development. Existing large infrastructural elements (including
the Keadby I power station, power distribution infrastructure and nearby wind
turbines) contribute to visual ‘clutter’ and reduce the sensitivity of the area.
Within the context of the existing Keadby I power station to the southeast, the
NG substation to the north, and the proposed Keadby II power station to the
south, it is not anticipated that the visual effect of the new transmission tower
and overhead line will be significant, either alone or cumulatively with other
development.

4.6 SOCIAL
The nearest large town is Scunthorpe approximately 5 km to the east. Other
settlements nearby include: Ealand and Crowle approximately 2 to 3 km to the
west; Althorpe approximately 2 km to the southeast; Gunness approximately
1.5 km to the east on the east bank of the River Trent; and Keadby
approximately 750 m to the east and southeast. A small number of individual
dwellings are found closer to the site: the closest is a single residential
building approximately 130 m to the northeast of the Proposed Development
site. Another residential building is located approximately 300 m to the south.
The Proposed Development will not displace employment, and will not be a
significant generator of employment opportunities at any stage. Construction
workers would be sourced from existing markets. There will be no significant
economic or demographic changes as a result of the Proposed Development.
Given the distance to the closest built up areas and the nature of the
construction and operational activities, there will be no significant effects on
these areas. The potential for the small number of nearby residential
receptors to be affected by the Proposed Development is considered in
Sections 4.5, 4.6, 4.9 and 4.10.
4.7 TRAFFIC AND TRANSPORT
The road infrastructure in the area is good. The wider SSE site is accessed
from the west by a dedicated access road from the A18 built to accommodate
construction vehicles. The Proposed Development site is adjacent to a public
road, Chapel Lane, which will also be crossed by the re-routed and new
overhead lines. This public road is not heavily used.
The construction activities for the Proposed Development and any associated
traffic will not result in any significant changes to the accessibility of Chapel
Lane. Ahead of construction works close to the road, including conductor
stringing over the road, a traffic management plan will be developed to
manage traffic flow along Chapel Lane. This will include use of appropriate
markers and safety signs along the road.
The level of construction traffic will be limited to the delivery of some
construction materials and equipment, and the movement of workers. All
traffic will access the site using the same routes used by traffic associated with
the Keadby II power station development (i.e. from the west using the
dedicated access road from the A18). During operation the amount of traffic
associated with the Proposed Development will be the same as for operation
of the existing overhead power line; i.e. very small. Traffic during both
construction and operation is expected to be minimal. Ahead of the start of
works a traffic management plan will be developed to manage traffic flow from
the Proposed Development.
4.8 RESOURCE USE
The Proposed Development will use water, materials and energy as part of
standard construction practice. The construction activities will be relatively
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
23
short term (6 to 8 weeks), and the requirements for materials will not be very
large. All of the materials required will be readily available as part of existing
supply chains for the SSE Keadby site, and are not in short supply locally.
The Proposed Development will not consume significant quantities of natural
resources that are not already in the supply chain or which are in short supply.
There are no high quality or scarce resources within or close to the
development site that could be affected by the development. No significant
effects arising from use of resources by the development, or affecting high
quality or scarce resources in the Proposed Development area, are
anticipated to occur.
4.9 EMISSIONS AND WASTE GENERATION
No hazardous, toxic or noxious substances will be released to the air during
construction or operation of the development, and therefore no significant
effects from emissions to air are anticipated to occur. Noise will be generated
by construction activities, and light will be produced by lighting of the
construction works, including security lighting. No noise or light will be
generated by operation of the Proposed Development. However, during
operation of the overhead lines electric and magnetic fields (EMF) will be
generated around the overhead lines.
The closest residential receptor is a building located approximately 130 m
from the proposed realigned overhead line and from the new transmission
tower. The construction works will be carried out as agreed with the local
planning authority, and within the existing legislative requirements of the
Control of Pollution Act 1974 and apply best practicable means to minimise
noise and vibration. Noisy activities, such as pile driving for foundations, will
not be carried out at night, and the overall duration of construction activities
will be relatively short. The proposed overhead lines will be designed to
comply with the statutory requirements of the Electricity Safety, Quality and
Continuity Regulations 2002, and with Government policy on optimum phasing
(Code of Practice: Optimum phasing of high voltage double circuit power lines’
(Ref. 16.14)). Noise, lighting and EMF from the Proposed Development are
unlikely to represent a significant change within the context of existing and
other proposed activities at the site (including the existing presence of
operational power lines within the immediate and wider area), and considering
the location and duration of the construction works.
There will be some wastes generated during construction of the transmission
tower and connection of the new overhead power line, such as packaging,
excavated materials and off-cuts from construction materials. There may be a
need to recycle or dispose of old cables following realignment of the overhead
line to the new tower. No solid wastes will be produced during operation of
the Proposed Development. The relatively small quantities of waste that will
be generated during construction will be recycled or disposed of using
standard waste management practices. No significant effects arising from
waste management are anticipated to occur.
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
24
4.10 FLOOD RISK
The Proposed Development is located within a zone of high flood risk. Breach
modelling conducted as part of the EIA for the Keadby II power station
development has indicated that existing flood defences are adequate to
control flooding at the site for a flood event from the River Trent. The site is
also at a residual flood risk from the Isle of Axholme inland drainage network.
The North Lincolnshire Strategic Flood Risk Assessment states that the critical
flood level for this area is 4.1 m above ordnance datum. The nature of the
Proposed Development means there is limited risk to it from flooding. If
flooding were to affect the Proposed Development area, it is anticipated that
the water would flow around the base of the new transmission tower and the
existing transmission tower with little impact on the structure and no contact
with critical elements, and no significant environmental effects.
4.11 HEALTH AND SAFETY
Standard operating methods and contractor health and safety management
procedures, during both construction works and the connection and operation
of the overhead lines, will ensure that there is a low likelihood of accidents
resulting from the development. There is a low residual risk of accidents
occurring during construction or operation of the Proposed Development.
The substances that will be used for construction are well known and the risks
associated with their use and storage well understood. No hazardous
substances will be used during operation of the Proposed Development. No
significant effects from substances causing actual or perceived risks to human
health are anticipated to occur as a result of the Proposed Development.
4.12 CUMULATIVE EFFECTS
The Proposed Development is planned as part of the development of the
Keadby II power station, and will enable the latter development to progress.
The development will not lead to consequential development. It is likely that
the programme for the Proposed Development will overlap with the
construction programme for the Keadby II power station, and therefore there is
potential for cumulative effects. The potential for cumulative effects has been
considered, particularly with the proposed Keadby II power station scheme.
Land and Water: the development of the overhead lines will make no
contribution to cumulative effects on land and water with the Keadby II
power station development.
Ecology: the overhead lines will not result in significant effects on ecology
receptors and will not contribute to cumulative effects on the same
sensitive receptors as the Keadby II power station scheme.
Noise: noise will primarily derive from the temporary construction period
and will not have cumulative effects on the same sensitive receptors as the
Keadby II power station scheme.
ENVIRONMENTAL RESOURCES MANAGEMENT SSE KEADBY SECTION 37 APPLICATION
25
Air Quality: very small amounts of traffic will be generated by construction
of the overhead lines and this will make a negligible contribution to
potential cumulative effects on air quality due to construction traffic
associated with the Keadby II power station scheme and the Lincolnshire
Lakes scheme.
Cultural Heritage: no known features of cultural heritage value will be
affected by construction of the overhead lines so there will be no direct
cumulative effects. Given the presence of numerous overhead lines in the
area, coupled with the industrial use at the site and its surroundings (i.e.
Keadby windfarm), the overhead lines will not result in cumulative effects
on setting of the same sensitive receptors as the Keadby II power station
scheme.
Transport and Travel: the construction traffic associated with the overhead
lines is unlikely to result in significant cumulative effects with the Keadby II
power station scheme and the Lincolnshire Lakes scheme. Ahead of
works commencing, a traffic management plan will be produced that will
include consideration of the potential for cumulative effects with Keadby II.
Socioeconomic characteristics: the small amount of employment
associated with the overhead line construction will make no material
contribution to either positive or negative cumulative effects.
Landscape and Visual Amenity: in terms of incremental change it should
be noted there has been power generation development on this site since
1952; the initial development took the form of the much larger coal-fired
power station with a bigger footprint. The wider area now contains the
Keadby I Power Station, multiple overhead lines and associated pylons
and a significant number of wind turbines in the immediate area. The
introduction of one additional pylon and overhead lines are unlikely to
make any material contribution to overall cumulative effects on landscape.

5 ENVIRONMENTAL MANAGEMENT CONCLUSIONS
5.1 MITIGATION AND ENVIRONMENTAL MANAGEMENT
In advance of construction, a Construction Environmental Management Plan
(CEMP) (or similar) will be finalised, in consultation with the local planning
authority and other relevant parties. The purpose of the CEMP will be to
manage the likely environmental effects of the works, through ensuring that
planned mitigation measures are implemented, unforeseen impacts are
managed and that standards of good construction practice are adopted
throughout construction. The requirements of third parties and the recognised
standard good practice for overhead lines design and construction will be
reflected in the CEMP. The CEMP will also provide a framework for auditing
of the environmental performance of the works. An outline CEMP is included
as Annex A.
The CEMP will be developed in conjunction with the appointed construction
contractor, and in consultation with North Lincolnshire Council. The CEMP will
reflect any conditions and obligations contained in the varied consent.
SSE’s approach to safety health and environmental (SHE) management is
accredited to ISO14001 and OHSAS18001, and the company has a SHE
policy in place.
5.2 CONCLUSIONS
The construction of overhead lines is a well-established practice and the
environmental effects of construction and operational presence are well
understood. The works will involve a single pylon and stringing of two sets of
cables on land with little or no associated environmental or socioeconomic
sensitivities. As a result of the nature of the surrounding area, in terms of the
existing power station, multiple pylons and overhead lines, substation and
wind turbines, the proposed overhead lines will be barely discernible once in
place.
Overall there will be no likely significant effects, including cumulative, during
construction and operation.

A1 INTRODUCTION TO THE OUTLINE CONSTRUCTION ENVIRONMENTAL
MANAGEMENT PLAN
A1.1 INTRODUCTION
SSE recognises the environmental impact of its business and uses its
expertise and innovation to ensure that the Company acts in a responsible
manner and continually works to reduce its impact on the environment.
SSE’s Environment Policy sets out minimum standards for the business in the
UK. SSE has certification to the International Standards Organisation's
Environmental Management Standard (ISO14001) for its power station
operations. The rest of the SSE business also operates to the same
standards. Further details on this can be found in the Environmental
Performance section within SSE’s Corporate Social Responsibility
Statement (1).
The Proposed Development consists of the realignment of one of Keadby I
power station’s existing overhead lines to allow connection of Keadby II power
station to the main Keadby 400kV National Grid substation. This will include
construction of a new transmission tower; realignment of an existing overhead
power line to the new tower; and stringing of a new section of power line from
Keadby II power station to an existing transmission tower (currently used for
the Keadby I connection). Further details of the Proposed Development are
provided in the Environmental Information Report (EIR) produced to
accompany the applications for consent for construction of the Keadby I and
Keadby II overhead lines.
SSE is committed to the highest standards of environmental performance for
the Proposed Development. To ensure this commitment is put into action,
SSE will require all of its contractors to comply with this Construction
Environmental Management Plan (CEMP) and to operate the necessary
Environmental and Safety Management Systems.
In addition to any specific monitoring and mitigation measures identified for the
Proposed Development in the EIR, the Proposed Development will conform to
general widely accepted environmental management practices.
The purpose of this strategic level document is to set out the framework for
effective environmental and social management during the construction of the
Proposed Development, to a sufficient level of detail to support the application
for the Proposed Development. The document and the management plans it
describes will be further developed as the Proposed Development progresses
through the detailed design and construction phases and will be adopted and
further developed by the Engineering Procurement and Construction (EPC)
contractor(s).

A1.2 PURPOSE OF THE CEMP
The broad purpose of the CEMP is:
to provide a mechanism for ensuring that measures to mitigate potentially
adverse environmental impacts are implemented;
to ensure that standards of good construction practice are adopted
throughout the construction of the Proposed Development;
to provide a framework for mitigating impacts that may be unforeseen or
unidentified until construction is underway;
to provide assurance to third parties that their requirements with respect to
environmental performance will be met; and
to provide a framework for compliance auditing and inspection to enable
the Company to be assured that its aims with respect to environmental
performance are being met.
This Outline CEMP contains a strategic level of detail and is in draft form. The
CEMP will continue to be developed as the Proposed Development proceeds
through the detailed design and construction phases, in consultation with
relevant bodies such as the Environment Agency and Natural England. The
CEMP will reflect any conditions, requirements and obligations contained in
the consent. The CEMP will be further developed prior to commencement of
works on the Proposed Development site in collaboration with the EPC
contractor (or contractors), who will have to demonstrate how it (or they) will
comply with these requirements as part of the tendering process.
A1.3 STRUCTURE OF THE REMAINDER OF THE CEMP
The remainder of the CEMP is structured as follows.
Section A2: general principles of the environmental management plan,
including roles and responsibilities, communications, training, monitoring,
inspection and auditing.
Section A3: SSE’s Company Policy on environmental management, and
legislation and codes of practice relevant to the project.
Section A4: environmental requirements with which all contractors will be
required to comply, organised on an environmental topic basis.
Appendix A: details of local authority and emergency contacts, to be
developed with North Lincolnshire Council prior to start of construction.
Appendix B: SSE’s Environmental Policy Statement.
Appendix C : outline Traffic Management Principles.

A2 GENERAL PRINCIPLES OF THE CEMP
A2.1 INTRODUCTION
The CEMP will be implemented through the designation of key roles and
responsibilities for environmental management (Section A4) and a series of
issue or activity-specific management plans that include statements of
environmental requirements and commitments (Section A5). These will be
developed in accordance with the underlying principles of good environmental
management set out below and will be further developed in consultation with
key stakeholders throughout the permitting and development process for the
Proposed Development.
A2.2 DESIGN AND CONSTRUCTION PRINCIPLES
The Proposed Development will be designed, constructed, operated, and
maintained in line with current best practice and to meet all relevant design
and safety parameters, with due regard to environmental and socio-economic
sensitivities within and adjoining the site and along access routes to and from
it. Mitigation minimising the impacts of the Proposed Development will be
embedded into the design through the use of industry standard methods and
procedures.
A2.3 HEALTH AND SAFETY PRINCIPLES
The safe operations and behaviours of the on-site workforce and contractors
during construction are a priority for SSE. Industry standards for health and
safety will be applied across the Proposed Development site and SSE will
seek continuous improvement in health and safety performance. The final
CEMP will outline the responsibilities of SSE, the contractor(s) and the EHS
manager with regard to health and safety, and will set requirements for
provision of facilities, training and signage in support of the safety of the
Proposed Development’s workforce.
The CEMP will:
define ‘permit to work’ procedures;
define the process of site inductions and how Method Statements and Risk
Assessments are developed; and
define how refresher training, learning points, toolbox talks etc are
provided.
A2.4 ENVIRONMENTAL MANAGEMENT PRINCIPLES
Environmental management issues throughout the life of the Proposed
Development will be governed or guided by a number of ‘standards’, including:
those contained in legislation;
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-5
those established by industry codes of practice;
those required by SSE’s environmental policy; and
commitments made in the EIR and applications, or during consultation,
and measures or conditions/requirements set out in any associated
permissions or consents granted.
The Proposed Development will be managed in line with the following
environmental management principles.
SSE will work and adhere to an Environmental Management System.
Contractors tendering for construction contracts will be required to provide
evidence of a management system that corresponds to the environmental
performance requirements of SSE’s management system.
The EHS manager for the Proposed Development will have authority over
the work of all contractors with regard to environmental management
issues.

A3 COMPANY POLICY AND RELEVANT LEGISLATION
A3.1 INTRODUCTION
SSE and its contractors will conduct their activities in such a way as to give full
consideration to the health and safety of their employees and any affected
persons, and give due regard to the conservation of the environment, in line
with relevant EU Directives, UK legislation, government guidance, industry
Codes of Practice and SSE policy.
A3.2 COMPANY POLICY
SSE’s Environment Policy Statement is attached as Appendix B to this
document. This sets out the approach of SSE and its employees to
management of the environmental impact of their activities. The Policy
applies to all SSE staff. The Policy is subject to annual review, and
environmental performance in line the Policy is also audited and assessed
annually.
The Policy provides guidance on how environmental issues should be
managed within SSE. Individuals must ensure that they act in accordance with
these documents and therefore act in an environmentally responsible manner
whilst at work. Where work carried out by staff forms part of work considered
under an Environmental Management System the specific requirements of the
system should be met at all times.
A3.3 LEGISLATION, STANDARDS AND CODES OF PRACTICE
This section outlines the European Directives, UK legislation, government
guidelines, industry standards and codes of practice relevant to the
construction of the Proposed Development. The list provided in Table A3.1 is
intended to highlight the key considerations only and should not be considered
exhaustive. It will be the contractors’ responsibility to put in place measures to
comply with all relevant legislation, standards and codes of practice, as well as
with the commitments made in the ES and with requirements that are relevant
to construction activities in the permissions and consents granted.

A4 ROLES, RESPONSIBILITIES AND REPORTING
A4.1 ENVIRONMENTAL MANAGEMENT ROLE OF SSE
SSE will have responsibility for:
ensuring the dissemination of information to the workforce and contractors
regarding required operations and behaviours;
monitoring the performance of contractors;
developing mechanisms for dealing with problems;
acting as the point of contact for consultation and feedback with
landowners, statutory consultees, the public and other interested parties;
and
the overall environmental management of the Proposed Development.
SSE will appoint an Environment, Health and Safety (EHS) manager who will
be independent of any of the contractors involved in the construction and will
be competent to undertake the environmental management of the project.
The EHS manager will be supported if required by an environmental auditor,
an ecologist and / or an archaeologist who will undertake regular audits of the
contractor(s) on behalf of SSE.
A4.2 ENVIRONMENTAL MANAGEMENT ROLE OF THE CONTRACTOR
The Proposed Development will be constructed under a contract covering
engineering, procurement and construction (EPC). In addition to statutory
obligations, the EPC contractor (or contractors) will be obliged to adopt the
environmental working practices operated by SSE, which will apply to all
works relating to the Proposed Development.
All contractors will be responsible for their own contribution to environmental
performance and for ensuring compliance with:
all relevant legislation and codes of practice;
the environmental controls and mitigation measures contained in the
CEMP;
all consent conditions relating to the Proposed Development and
associated permits and licences; and
any environmental or other codes of conduct required by SSE.
The performance of the Contractor, and compliance and non-compliance with
the provisions of this CEMP will be established through regular environmental
inspections and reporting by the Contractor, and regular monitoring and audits
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-13
by SSE. This information will be recorded by the SSE project team and
records will be held in the site office and available for inspection. The SSE
EHS manager will be empowered to stop the works if he or she is of the
opinion that the provisions of the CEMP are not being met.
A4.3 EXTERNAL COMMUNICATIONS
SSE will be responsible for formal external communications, including all
consultation processes, events and communications, and the provision of
adequate complaints and grievance mechanisms. SSE will manage all
communications with the media.
SSE will maintain open lines of communication with the local population
throughout the development, construction and operational phases of the
Proposed Development. A Local Liaison Committee is to be established at
the start of construction of Keadby II. The same committee will provide a
forum through which the local community can be kept informed on progress of
works related to the Proposed Development, the overall programme and key
activities that are due to start and may affect them. This will provide a channel
for local people to raise concerns associated with the construction activities
with SSE and its contractors so that these can be addressed. A complaints
procedure will also be set up ahead of construction of Keadby II, which will
enable any complaints to be made directly to a nominated individual (normally
the SSE EHS manager). The complaint will be investigated by the SSE EHS
manager or another member of the SSE project team and appropriate action
taken where necessary. Records of all such complaints and actions will be
maintained on site. The complaints procedure will also apply to the Proposed
Development.
A4.4 TRAINING
Contractors will be responsible for ensuring that all personnel are aware of
their responsibilities with respect to the CEMP, and that the plan is
implemented in an appropriate way. Contractors will ensure that personnel
with specific environmental management responsibilities have the necessary
experience, have a good understanding of the environmental sensitivities in
the Proposed Development area, and have received appropriate training.
Contractors will keep records of the training given to individual staff. Training
will be assessed as part of the environmental audits carried out by SSE.
Contractors will be required to ensure that all construction personnel undergo
site specific induction to include health, safety and environmental issues,
before commencing work on the site.
A4.5 ENVIRONMENTAL LABELLING
Contractors will be required to erect notices on site to indicate environmentally
important and/or sensitive areas crossed by the works, including any trees
protected by Tree Preservation Orders (if any are present), proximity to
special sites and conservation areas, and areas affected by animal or plant
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-14
disease precautions. This will add to the environmental awareness of the
construction personnel.
A4.6 ENVIRONMENTAL MONITORING DURING CONSTRUCTION
Monitoring of the environmental effects of construction will enable the
effectiveness of environmental mitigation to be evaluated, and if necessary
facilitate improvement being made. It will also allow environmental problems
to be identified and responded to at an early stage.
Potential issues that may require monitoring could include (but are not limited
to): sensitive habitats and protected species; presence of contaminated soils;
presence of archaeological features; generation of airborne dust and gaseous
emissions; quality of discharged or drainage water; construction noise;
excavated soils; traffic movements; waste management; and site lighting.
The locations, durations and frequencies of monitoring activities will be
focused on activities and areas of most potential risk. SSE will ensure that an
appropriate programme of environmental monitoring is implemented.
Monitoring programmes will be incorporated in issue-specific site
environmental control plans, where applicable. SSE will ensure that
contractors are advised of monitoring requirements as specified by conditions
or other consents as they are obtained.
A4.7 INSPECTION AND AUDITING
Contractors will be required to undertake a programme of environmental
inspections and audits appropriate to their scope of work, and to demonstrate
to SSE that their responsibilities under the CEMP are being fulfilled. In
addition, SSE will carry out periodic environmental audits of contractors, as
appropriate, to verify compliance with the CEMP. Where problems are
identified by either SSE or a contractor during inspections and/or audits,
corrective action will be agreed and implemented by the contractor. This could
take the form of, for example, further direct mitigation, changes to procedures
or additional training.
A4.8 CONTINGENCY PLANNING FOR EMERGENCIES AND ENVIRONMENTAL INCIDENTS
Procedures to deal with emergencies and environmental incidents will be set
out in a specific site emergency response plan. Environmental incidents can
be defined as unexpected events which lead to, or could in different
circumstances have led to, adverse effects on people, property or on
environmental resources such as natural habitats or watercourses. SSE and
its contractor(s) will develop a series of plans which will set out the response
in the unlikely event of an incident occurring during construction such as a fuel
spillage or a period of unexpectedly high noise or dust levels. The procedures
will include provision for incident reporting.
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-15
A4.9 SAFETY
Safety on the construction site will be managed effectively by SSE through all
phases of the project. SSE places safety at the top of its agenda and will not
tolerate the use of unsafe practices by its staff or its contractors.
Construction Safety will be addressed throughout the design phase of the
project to ensure that the design develops in a way which minimises the risks
both during operation and during construction.
All contractors shall be required to prepare and maintain a set of procedures
for each work site which shall be displayed prominently at each site. These
procedures shall be followed in any site emergency and shall include contact
details for the Contractor’s management. They shall also contain emergency
phone numbers and the method of notifying local authorities/services for
action by the contractor and SSE and site staff. Copies of the procedures will
be issued to the Local Authority, the Fire Brigade, the Police, the Ambulance
Service and the relevant statutory authorities. Emergency telephone numbers
for the contractors’ key personnel shall also be included.
A4.10 INVITATIONS TO TENDER
All prospective contractors will be required to include, within their tenders, a
description, appropriate to their proposed scope of work, of the way in which
they will address the requirements of the CEMP. This will include in particular,
a description of how the contractor intends to address the general
requirements of the CEMP as set out in Section A2; and if appropriate
example Method Statements showing how the contractor will address the
environmental requirements set out in Section A5 of this CEMP.
The next revision of the CEMP, prior to construction, will contain a series of
specific environmental requirements.
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-16
A5 SITE-WIDE ENVIRONMENTAL REQUIREMENTS
A5.1 INTRODUCTION
This section of the CEMP sets out a series of site-wide environmental
requirements with which all contractors will be required to comply. These are
organised on an environmental topic basis and set out requirements for that
topic over the whole site.
The topics covered are:
general site practice;
archaeology;
dust and other emissions to air;
protection of flora;
noise and vibration;
water resources;
waste management;
fuel storage and handling; and
lighting.
Prospective contractors will also be referred to the outline Traffic Management
Principles presented in Appendix C and will be required to produce their own
detailed traffic management procedures based on these principles.
A5.2 GENERAL SITE PRACTICE
Contractors undertaking work with potential for environmental impact, will
formulate a general site practice method statement to control the potential of
nuisance arising during construction works, for approval by SSE. Contractors
will be required to demonstrate the use of Best Practicable Means to prevent a
statutory nuisance from occurring and must ensure compliance with any
conditions imposed during the consenting process. In particular, contractors
will use Best Practicable Means to identify potential causes of nuisance, and
where they may occur, and to manage and dispose of all waste from the
Proposed Development, including sewage waste.
A5.3 ARCHAEOLOGY
SSE will require full co-operation in the sensitive handling of the area’s
heritage by all those whose actions could potentially cause damage to
archaeological sites and finds, irrespective of whether the sites are currently
known or likely to be revealed during construction.
The Screening Report has assessed the potential for archaeological resources
to be present within the footprint of the Proposed Development and it is not
anticipated that major archaeological remains will be encountered during
construction. Prior to construction, site investigation work will be conducted
that will be monitored by an archaeological advisor, in the form of a ‘watching
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-17
brief’. This advisor will be appointed by the Company or the Contractor, and
approved by the County Archaeologist. If evidence of buried archaeology is
discovered, construction work will be stopped and the area of archaeological
interest demarcated and signposted while a plan for the preservation of the
remains, if required, is developed. This plan will include consideration for how
to protect the remains during ongoing construction works. All archaeological
fieldwork will be undertaken in accordance with the standards and guidance of
the Chartered Institute for Archaeology.
A5.4 DUST AND OTHER EMISSIONS TO AIR
SSE will ensure that a site procedure is prepared and implemented by the
relevant contractors for the control of fugitive dust and emissions during
construction. The use of Best Practicable Means is likely to include, but not
be limited to, the following:
measures for the storage and handling of spoil, sub-soils and top-soils;
measures for the control of vehicle movements on site;
measures for the control of site operations; and
measures for the avoidance of nuisance from exhaust emissions.
The relevant contractors will be responsible for implementation of dust
suppression measures (eg damping of ground; cleaning of vehicles and areas
of hardstanding; protection of dust sensitive areas; traffic management), and
for having appropriate approval from the EA in place for use of any chemical
agents for the purpose of dust suppression. The Contractor will also ensure
that all vehicle and equipment engines and exhaust systems are maintained
and used so that exhaust emissions do not breach statutory limits set for that
vehicle/equipment type and mode of operation, and that all vehicles and
equipment are maintained in accordance with manufacturers’ guidance.
A5.5 PROTECTION OF FLORA AND FAUNA
The Contractor will be required to take all necessary measures to minimise
adverse effects on habitats and wildlife during construction. Particular
attention must be paid to sensitive habitats and species protected under the
Habitats Regulations 2010, following the implementation of the Habitats
Directive (Council Directive 92/43/EEC on the conservation of natural habitats
and of wild fauna and flora) and the Birds Directive (Directive 2009/147/EC of
the European Parliament and of the Council) and other relevant legislation,
such as the Countryside and Rights of Way Act 2000.
Construction activities will be conducted as far as possible outside of the bird
breeding season (reasonably being regarded as 1st April to 31st July given
the northern location), to reduce the likelihood of disturbing bird species that
may be present in the wider area.
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-18
A5.6 NOISE AND VIBRATION
Contractors will be required to apply the ‘Best Practicable Means’ (BPM), as
defined in the Control of Pollution Act 1974, to reduce emissions of noise and
vibration throughout the construction contract. This will incorporate the use of
measures to control noise that do not unreasonably inhibit the work, and the
use of working methods that result in minimum noise effects compatible with
normal working practices. Contractors will implement the general principles
and working practices to control noise as detailed in the Codes of Practice
comprising British Standard BS5228 ‘Noise and vibration control on
construction and open sites’ 1997. With specific regard to piling operations,
the approved code of practice for noise control applicable to piling shall be
BS5228: Part 4: 1992. Noise control measures will include use of quiet plant,
which conforms to relevant EC Construction Equipment Noise Directives, and
which is properly equipped, used, maintained, checked and serviced so as to
prevent unnecessary noise emissions, and sited so as to minimise effects on
noise sensitive receptors.
Construction hours will be agreed with the local planning authority. It is
proposed that working hours will be in line with those proposed for the
Keadby II development: Monday to Friday 07:00 to 19:00, and 08:00 to 14:00
on Saturday. Pile driving for foundations and other noisy activities will be
limited to Monday to Friday 08:00 to 18:00, and 08:00 to 14:00 on Saturday,
and the timing of such activities will be communicated to any potentially
affected occupied buildings. The transport of materials on or off site by road
will take place during the normal daytime working period and will be routed
away from particularly sensitive receivers in accordance with the Traffic
Management Plan.
A5.7 PUBLIC RIGHTS OF WAY
SSE will be responsible for ensuring that any necessary Public Right of Way
diversion or stopping-up Orders are obtained prior to construction.
Contractors must not obstruct any footpath, bridleway or other public highway
unless the appropriate permission has been obtained.
A5.8 SOILS HANDLING
A Soil Management Plan (SMP) will be developed in line with DEFRA
guidance. The main objective of the SMP will be to mitigate impacts on soils
by preserving the ecologically (and economically) valuable topsoil. No topsoil
shall be removed from site unless specifically agreed with SSE and
specifically authorised. Topsoil shall not be used for backfill, packing, or any
other purposes. Contractors shall take all necessary precautions to alleviate
topsoil storage loss. Any topsoil loss due to contractual negligence shall be
replaced with topsoil covered by all the necessary certification, acceptable to
SSE and all parties concerned. Topsoil will be stored for the minimum time
practicable, and topsoil mounds will be designed, sited and maintained so as
to prevent any deterioration in quality. Topsoil will be reinstated in dry
conditions on appropriately contoured and prepared subsoil, in the area from
which it was removed. The topsoil will be spread to an even depth and
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-19
matched to the existing levels on the site. Final grading will be conducted to
remove any pronounced local mounds or depressions, and to match the
existing contours of the site. Any area that becomes unduly compacted during
the final grading operation will be loosened by forking or cultivation as
necessary.
Excavated subsoil will be stored separately from topsoil, and prevented from
mixing where relevant by placing a layer of geotextile membrane between
them. Subsoil layers of significantly different quality will be excavated and
stored separately. Prior to replacement, the excavated subsoil will be graded
and if necessary processed to remove large stones and render the soil
sufficiently friable for use. The graded subsoil will then be backfilled and
compacted to grade level. Any groundwater that has collected in the
excavation will be removed prior to backfilling and disposed of in accordance
with the requirements of the EA. Once backfilling is complete, the site will be
graded to the pre-construction level.
Following final grading, all areas of bare topsoil shall be cultivated to
approximately the full depth of the topsoil, taking care not to bring subsoil to
the surface or within the topsoil limits. The re-instated area will be fertilised
and re-seeded using an appropriate seed mix to match the surrounding
grassland. Aftercare will be carried out by the contractors as required to
destroy weed growth.
The Contractor will ensure that unnecessary soil disturbance in surrounding
land will be avoided, in order to prevent the spread of any plant and animal
diseases in the soil. Should any animal remains be discovered during the
course of the works, the SSE Project Manager will inform the duty Veterinary
Officer at the Divisional Animal and Health Office so that the reburial (or other
means of disposal) of the remains can be authorised as set out in the MAFF
publication ‘Preventing the Spread of Plant and Animal Diseases - A Practical
Guide’.
A5.9 PROTECTION OF WATER RESOURCES
Contractors will be required to take all necessary precautions to prevent the
pollution of controlled waters. Pollution prevention measures will be
developed adopting the principles established in the following EA Pollution
Prevention Advice and Guidance (PPG) notes:
PPG1 - General Guide to the Prevention of Water Pollution;
PPG2 - Above Ground Storage Tanks;
PPG5 - Works in, Near or Liable to Affect Watercourses;
PPG6 - Working at Construction and Demolition Sites; and
PPG8 - Safe Storage and Disposal of Used Oils.
SSE will develop, in consultation with the EA, its advisors and relevant
contractors, a site water management and drainage procedure for contractors
setting out the measures to be implemented to control the relevant
construction activities and ensure that consent conditions are complied with.
This procedure will cover control of vehicle movements and vehicle cleaning
ENVIRONMENTAL RESOURCES MANAGEMENT KEADBY DEVELOPMENTS LIMITED
A-20
activities; drainage measures; disposal of waste waters and other liquid
effluents; and response measures in the event of a pollution incident.
Every precaution will be taken to prevent silting, erosion and pollution of rivers,
streams, ditches, land drains and other water bodies during construction
works. If, notwithstanding these precautions, such silting, erosion or pollution
does take place, then the EA shall be advised immediately and immediate
action shall be taken to minimise the effect on the watercourse and to prevent
any reoccurrence of the event.
A5.10 WASTE MANAGEMENT
The Project will meet the requirements of the Site Waste Management Plan
(SWMP) Regulations 2008, which require that all construction projects
incurring costs in excess of £300,000 produce and follow a Waste
Management Plan (WMP) in consultation with EA. The WMP will act to
minimise the volume of waste and ensure that on-site reuse is maximised.
Where appropriate, all contractors will be required to formulate Waste
Management Method Statements, to ensure the appropriate handling and
disposal of all wastes arising from the construction works, for approval by
SSE. The WMP will include measures to minimise generation of waste for
disposal and to make use of recycling where appropriate; measures to
manage different waste streams separately; and procedures for tracking
wastes that leave the site. All waste will be disposed of at facilities or sites
licensed to accept such waste. No waste will be disposed of without a licence.
A5.11 FUEL STORAGE AND HANDLING
Contractors will be required to implement measures for the safe storage and
handling of all fuels and lubricant oils on site. Fuel, lubricant oil and chemical
storage areas will be bunded and have impervious bases. Equipment and
plant will be inspected prior to use and regularly thereafter for any fuel and oil
leaks, and leaking containers will be removed from site immediately.
Refuelling areas will be sited away from waterbodies or drains. Drip trays will
be installed to contain leakage from equipment such as generators and
pumps.
A5.12 LIGHTING
Site lighting during construction shall be positioned and directed as so to
minimise nuisance to residents and to minimise distractions or confusion to
passing drivers on adjoining public highways. This provision will apply
particularly if construction works take place through the winter period when
working in darkness. Contractors shall comply with the Institute of Lighting
Engineers document Guidance Notes for Reduction of Light Pollution 2000
(revised 05/03).

APPENDIX C OUTLINE TRAFFIC MANAGEMENT PRINCIPLES
The following principles will be incorporated into a Traffic Management Plan
(TMP) for the Proposed Development. Contractors will be required to develop
their own detailed traffic management procedures. The detailed procedures
will follow the principles in the TMP, including the following:
Preferred routes for HGVs to the sites will be identified and agreed with the
local highway authorities;
Speed activated warning signs will be provided by SSE where required;
On-site wheel cleaning facilities will be provided to prevent the tracking of
mud and all Contractors will be required to use these;
Site roads and the highway near site accesses will be kept free from dirt
generated by construction activities;
All HGV movements will be confined to a designated operational period,
during day time hours; the precise hours will be agreed with the highway
authority;
Traffic will be managed during the construction phase to avoid the village
of Keadby. All contractors will ensure that all drivers will be informed of
the requirement to drive slowly and safely through any villages on their
routes and on all approaches to the sites. Supplementary road signs
enforcing such instructions may also be erected.
Warning signs indicating the presence of construction sites and directing
construction traffic will be erected.
HGVs will display contact numbers for the public to use to report any
issues associated with HGV movements
All contractors and sub-contractors will be encouraged (using incentives if
necessary) to employ car sharing schemes and the use of minibuses, in an
attempt to minimise the volume of worker related traffic generated by the sites,
where this is feasible.
