Non Technical Summary 1.Introduction
1. The Environmental Statement (ES) of which this Non Technical Summary (NTS)
forms part, has been submitted by QPI Global Ventures Limited (the Applicant), on behalf of itself, ExxonMobil Power Limited (ExxonMobil) and Total Gas and
Power Business Services S.A.S. (together the Developers) to accompany its
application for a Development Consent Order (DCO) to the National
Infrastructure Directorate of the Planning Inspectorate (PINS) to construct and
operate a combined heat and power (CHP) plant (the CHP Plant) within the
existing boundary of the South Hook Liquefied Natural Gas (LNG) Terminal (the
LNG Terminal) near Herbrandston, in the county of Pembrokeshire, Wales.
2. This document is the Non Technical Summary of the ES. The ES comprises
four volumes:
Volume 1: Text (Document 1.3.1).
Volume 2: Figures, Photographs and Photomontages (Document 1.3.2).
Volume 3: Technical appendices (Document 1.3.3).
Volume 4: Non Technical Summary (Document 1.3.4).
2. Overview 3. The Application Site is mainly located within Pembrokeshire Coast National Park
(PCNP) and also comprises land within the jurisdiction of Pembrokeshire County
Council (PCC). The Application Site is centred at National Grid Reference SM
874 and is shown on the Site Location Plan (Figure NTS 1). The Application Site
itself is the area within the Order Limits Boundary (as shown on the Proposed
Site Layout Plan, Figure NTS 2). The electricity generating station and
associated infrastructure (the Main CHP Plant Site) will occupy an area of
approximately 10 hectares (ha) (again, as shown on the Proposed Site Layout
Plan, Figure NTS 2). In addition the required area for a future carbon capture
2 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
facility will occupy an area of approximately 4ha. Overall however, taking into
account drainage and access requirements and the required interconnections
with the LNG Terminal, (principally comprising fuel and cooling integration with
the modified submerged combustion vaporisers (SCVs)) the area within which
permanent works will be undertaken will amount to approximately 31ha. In
addition a further 30ha of land will be required for temporary land works during
construction.
4. The DCO will authorise the construction and operation of the CHP Plant which
will have a nominal gross electrical output capacity of up to 500 MW electrical
(MWe) and as such the proposed development (or Scheme), falls within the
thresholds for nationally significant infrastructure projects (NSIPs). Under
normal operating conditions the CHP Plant will be fully integrated with the
working of the adjacent LNG Terminal with the heat from the CHP Plant being
used to vaporise LNG which is then fed into National Grid Gas plc's National
Transmission System for gas (the Gas NTS).
5. In addition all the power generated by the CHP Plant will be either exported to
the electricity grid or to other industrial sites adjacent to the Milford Haven
Waterway, or will replace power currently imported by the LNG Terminal.
Building the CHP Plant will produce enough electric power to supply up to
900,000 homes, and significantly reduce gas utilisation by the LNG Terminal.

Terminal via its subsidiary Elf Petroleum UK Limited.
4. Site Context
Pembrokeshire Coast National Park
10. The Application Site is located straddling the edge of the Pembrokeshire Coast
National Park within an area of countryside typified by gently undulating hills and
valleys. However, the landscape in this part of Pembrokeshire is also
dominated by the significant industrial installations adjacent to the Milford Haven
Waterway (the Waterway) including oil refineries, power stations, LNG
terminals, storage terminals, docks, a ferry terminal, marinas, jetties and vacant
former industrial sites. The Application Site itself occupies part of the area of
the former Esso oil refinery that was closed in 1983. The boundary of the PCNP
bisects the LNG Terminal site, of which the Application Site forms part, from
north to south such that the western part of the LNG Terminal site lies within the
PCNP; nevertheless the landscape characteristics that prevail are largely
maritime industrial.
4 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
Pembrokeshire Coast Path and Amenity Assets
11. The Pembrokeshire Coast Path National Trail (part of the All Wales Coastal
Path) (the Coastal Path) follows the northern and southern coastline of the
Waterway and the western and southern boundary of the LNG Terminal site
closest to the Application Site between Sandy Haven and Gelliswick Bay.
12. The Milford Haven Golf Club course lies to the east of the Application Site and
borders the eastern boundary of the LNG Terminal site.
Local Communities
13. There are several small settlements close to the Application Site including the
small village of Herbrandston approximately 1.5km to the north, Hubberston,
Hakin and other residential areas of Milford Haven approximately 2km to the
east, and Upper Neeston approximately 1km to the north east. The small
hamlet of Angle is located some 3km to the south across the Waterway.
14. The larger communities of Milford Haven and Pembroke Dock are located some
3km to the east and 8km to the south east of the Application Site respectively.
Nearest Residential Properties
15. The nearest residential properties are located just under 1km to the north from
the main noise generating equipment in the CHP Plant (e.g. the gas/steam
turbine generator building). Further to the north are the dwellings of the village
of Herbrandston, including Herbrandston Hall and the isolated property at Big
Neeston. To the east and south east there are a number of residential
properties on South Hook Road in Gelliswick.
Historic Environment
16. The Application Site lies within the Milford Haven Waterway Landscape of
Outstanding Historic Interest. As a result of this designation it is considered to
be a highly articulate and distinctive land and seascape which exhibits both
continuity and adaptation, and its overall setting and range of features make it
unique in Wales. The wider landscape encompassing the site consists of a
5 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
combination of open rural landscape, heavy industry, villages, towns, and the
Waterway.
17. The landscape around the Waterway has been strongly influenced by its past
and present industrial land uses. The settlements of Pembroke, Milford Haven
and Neyland originated as a result of fishing, trade, boat building and maritime
transport. More recently, the deep waters of the Waterway have allowed the
Waterway to receive deep draught vessels for bulk cargoes from the sea,
leading to the development of a large petrochemical industry in the area.
5. Alternatives 18. Given the proposed synergistic relationship between the CHP Plant and the
LNG Terminal the only locations considered by the Developers for the Main
CHP Plant Site were all within the LNG Terminal site on land previously
identified in the planning permissions granted for the LNG Terminal for “future
expansion”.
19. Initially five possible locations within the LNG Terminal were considered for the
CHP Plant. Using a range of selection criteria these were reduced to a western
and an eastern potential development zone which were the subject of the
Preliminary Environmental Information Report and associated consultation in the
late summer of 2012. As a result of that consultation the Developers decided to
select the western option.
20. Since then a small number of alternative layouts have been considered for the
western site, mainly in response to engineering requirements and to optimize
the integration with the LNG Terminal site. Architects were appointed and
further refinements were subsequently made, partly in response to concerns
from the residents of Herbrandston on the visual impact of the Scheme.
21. At the outset five standby cooling options were being considered – once through
seawater cooling, hyperbolic natural draft cooling towers, air cooled condensers,
a mechanical draft wet closed-loop cooling system, and direct air-cooled fin fan
coolers. After careful consideration of the engineering, operational and
6 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
environmental merits of each standby cooling option, the direct air-cooled fin-fan
coolers were selected.
22. During the design of the Scheme slightly different plant layouts have been
examined primarily to optimise operating efficiency, and alternative architectural
concepts for the ‘mitigate by design’ approach adopted have been considered.
These have been discussed with Pembrokeshire Coast National Park Authority
(PCNPA) and PCC. In addition, in order to allow for further design evolution
and development and to provide sufficient flexibility in the final design, a
maximum or worst case parameter (Rochdale Envelope) approach has been
adopted for the main buildings/structures in the Scheme (see Section 36 of this
NTS) enabling the environmental impact assessment to be undertaken robustly.
23. A key objective in developing the design philosophy for the proposed CHP Plant
is to provide a high quality appearance that, despite being distinctive, also
succeeds in reducing the visual impact of the CHP Plant having regard to its
surroundings and views from key visual receptors.
6. The Scheme 24. Full details of the Scheme are set out in Chapter 4 of the main text in Volume 1
of the ES, together with its appendices. These are summarised as follows.
25. The CHP Plant will burn natural gas to generate electricity and heat. Heat
generated by the CHP Plant steam turbine condenser system will be utilised
within the LNG Terminal to vaporise LNG, turning it back into natural gas,
making this the largest operational high efficiency CHP Plant in the UK. A
combined-cycle system with co-generation of heat and power offers a high
degree of energy efficiency, with a thermal efficiency of up to 88%.
26. The CHP Plant will provide heat to the LNG Terminal during normal operation,
but both facilities will also be designed to enable independent operation, as set
out below - if one of the facilities is unavailable for any reason.
27. The four main modes of operation are the following:
7 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
Integrated mode (normal operating condition) – the CHP Plant operating
as designed with heat being provided to the LNG Terminal for LNG
vaporisation;
Independent mode (a) – the LNG Terminal operating as it currently does,
without a heat supply from the CHP Plant (e.g. due to CHP Plant
maintenance);
Independent mode (b) – the CHP Plant operating but not providing all of its
heat to the LNG Terminal due to lack of heat demand (e.g. due to the LNG
Terminal having a low gas send-out demand and hence a low heat demand);
Independent mode (c) – both the CHP Plant and the LNG Terminal
operating with the requisite supply and demand of heat available, but without
heat being provided to the LNG Terminal (e.g. due to the hot and return
water lines between the CHP Plant and the LNG Terminal being unavailable
as a result of maintenance during a period of high demand for gas and
electricity).
28. In normal operation, the CHP Plant is designed to meet the LNG Terminal’s
demand for heat when the LNG Terminal is operating at 70% of its maximum
gas send-out capacity. In this mode of operation there will be a reduction of
approximately two thirds of the consented discharges (under the LNG Terminal
environmental permit) to atmosphere from the SCVs, approximately equivalent
to the emissions from 10 SCVs.
29. All of the above modes of operation result in a reduction in emissions from the
LNG Terminal, with the exception of independent mode (c). It is extremely
unlikely, however, that a period of high demand for both gas and electricity will
coincide with unavailability of the hot and return water lines, which means that
independent mode (c), whilst possible, is unlikely to occur in practice.
30. The early design stages for the Scheme have been completed, informed by the
iterative environmental analyses undertaken as part of the Environmental
Impact Assessment (EIA) and Habitats Regulation Assessment (HRA)
processes and the consultation process mandated by the Planning Act 2008 as
8 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
amended (the Planning Act). The final detailed design will be completed within
the constraints set by the DCO application and is due to be completed by the
end of 2013. Subject to the timing of the DCO process, the expected
programme for construction and operation is:
construction commencing mid to late 2014;
commissioning commencing mid to late 2016; and
commercial operation commencing 2017.
Overview of Current and Proposed Operation at the LNG
Terminal
31. The LNG Terminal receives, stores and vaporises LNG for ultimate supply to the
Gas NTS. The LNG Terminal has the capacity to process up to 15.56 million
tonnes of LNG per year. Vaporisation of LNG is currently achieved by operation
of up to 15 SCVs, the number of units operating at any given time being
dependent on gas send-out requirements. Each SCV comprises a stainless
steel tube bundle immersed in a warm water bath. The LNG flows through the
tube bundle and is heated and vaporised by heat transferred from the water
bath. The warm water temperature is maintained by supplying heat to the water
in the SCVs through direct contact with hot gases resulting from the combustion
of a small portion of the re-gasified natural gas produced at the LNG Terminal.
32. Modifications to the existing SCVs and associated plant are required to enable
heat recovered from the steam turbine condenser system of the CHP Plant to be
used, with the remainder being able to continue to operate as installed, if
required. The modifications to the selected SCVs will include the following:
modifications to the SCV bath to accommodate hot water circulation;
installation of water mixers on the deck of each SCV;
installation of hot water and return lines between the SCVs and the CHP
Plant; and
construction of water sumps and return pumps.

CHP Scheme Overview
33. In summary, the DCO application seeks consent for the CHP Plant which
comprises the main generating plant and other integral infrastructure within the
Application Site. The CHP Plant is described in detail in Schedule A of the draft
DCO (Document 1.4) and includes an electricity generating station with a
nominal gross electrical output capacity of up to 500MWe including:
Gas/steam turbine generator building containing gas turbine generator set
and steam turbine generator set;
Administration office and control room;
Workshop and maintenance/warehouse building;
Electrical sub-station (HV switchgear indoor gas insulated building and
compound) and electricity transformer;
Heat recovery steam generator building containing heat recovery steam
generator set;
Standby direct air-cooled fin-fan coolers;
Raw/fire water storage tank, pump house, pipework and hydrants;
Demineralised water storage tank, demineralised water treatment plant, and
pipework;
Stack for discharge of flue gas;
Fuel gas lines (1) from existing connection to the Gas NTS and (2) from the
LNG Terminal, and gas receiving station;
Electrical supply power lines;
Water treatment equipment;
Electrical export line to electrical sub-station;
Pumps;
Hot and return water lines, and support structure (where lines not buried);
10 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
Security fencing, gates and kiosk(s); and
Process waste water treatment plant and pipes to process waste water
discharge point.
34. Also included within the CHP Plant and the Application Site are the following
elements and requirements:
Integration of hot and return water lines into existing LNG Terminal SCVs;
Ground grading, levelling and landscape works;
Partitioned attenuation basin and associated surface water infrastructure;
Foul water drainage system;
Secure access corridor for utilities infrastructure and internal site roads;
Open storage of excavated materials; and
Land reserved for carbon capture.
35. Temporary land requirements include:
Land for preparatory works including demolition;
Contractors' car parking, offices, canteen, welfare and related support
facilities;
Open and covered storage, construction laydown areas, warehouse,
workshops and stores; and
Open storage of excavated materials.
Design Parameters
36. The key buildings and structures forming part of the CHP Plant together with
their maximum dimensions or parameters are set out in the following table.
11 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
Building/Structure Dimensions (metres)
Height Length Width
Gas/Steam Turbine Generator Building 30.5 m 126 m 101 m Administration Office and Control Room 19 m 66 m 34.5 m Workshop and Maintenance/Warehouse Building 20 m 65 m 35 m

Heat Recovery Steam Generator Building 42 m 66 m 50.5 m Standby Direct Air-cooled Fin-fan Coolers 22 m 142 m 101 m Raw/Fire Water Storage Tank 16 m 21 m (diameter) Demineralised Water Storage Tank 16 m 21 m (diameter) Stack Up to 85 m Up to 8 m (external
diameter)
37. Other structures on the Application Site include a revised surface drainage
system and new permanent perimeter fencing, security gates and access.
Drainage System and Process Water Discharge
38. Dedicated surface water and process waste water drainage systems will be
established for the CHP Plant in accordance with a drainage plan agreed with
Natural Resources Wales (NRW, formerly, in this context, the Environment
Agency Wales). Process waste waters will be treated within the process waste
water treatment plant for the CHP Plant. After treatment these will discharge
into the LNG Terminal process waste water effluent pipeline, with the combined
discharges from the CHP Plant and the LNG Terminal ultimately discharging
from the existing LNG Terminal discharge point into the Waterway under the
applicable conditions for the substances specified in the the existing permit for
the LNG Terminal.
Waste water from Amenities 39. Waste water from amenities (such as toilets and canteens) will be connected to
the LNG Terminal’s foul water drainage system and discharged to the existing
12 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
foul water sewer connection, which has sufficient capacity to accept the
anticipated flow of approximately 0.1 m3 per hour.
Access and Traffic Movement
40. Access to the CHP Plant will be via the existing road network junction and
entrance to the LNG Terminal. There will be no vehicle movements associated
with the delivery of primary fuel to the CHP Plant as this will be piped direct from
the adjacent LNG Terminal, or if not available from the LNG Terminal, from the
Gas NTS.
Hours of Operation and Shift Pattern
41. The CHP Plant will be designed for continuous operation, except for
maintenance periods, with the operational flexibility to work on a shift basis
when commercially desirable to do so.
42. The CHP Plant is expected to employ around eight full time day staff and 25 full
time shift workers split between five rotational shifts. During days this will mean
a total of 13 employees working on-site, reducing to approximately five at nights
and at weekends. There will be some additional cleaning/grounds/security
personnel, though numbers at present are unknown and will depend on the
extents of cross-sharing of these resources with the LNG Terminal.
7. Environmental Impact Assessment 43. The Scheme requires Environmental Impact Assessment as it is a thermal
energy generating facility with an installed capacity in excess of 300MW and
falls within the description of projects contained in Schedule 1 of the
Infrastructure Planning (Environmental Impact Assessment) Regulations 2009
(the EIA Regulations 2009). This NTS is provided in accordance with the EIA
Regulations 2009.
44. The ES records the results of the EIA which has examined the effects of the
Scheme during its construction, operational and decommissioning phases on a
wide range of environmental topics. These topics were agreed with PINS
13 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
through a formal EIA scoping process. The ES also considers the cumulative
effects of the CHP Plant with other major developments in both the vicinity of the
Waterway and wider afield in Pembrokeshire and adjacent counties.
45. All the environmental topics were assessed using the following key baselines:
The existing situation in 2010 - 2012;
A future baseline of 2017 - which is when the CHP Plant will become
operational; and
A future baseline of 2032 for traffic data and related assessments only (e.g.
noise and air quality).
46. Where relevant, consultation was undertaken with the local authority and
prescribed consultees to determine study areas, methodology and mitigation
measures for each environmental topic.
47. The purpose of an EIA is to describe “the likely significant effects of the
development on the environment”. Where sufficient information and knowledge
exists a three stage approach is normally adopted to determine the likely
significant effect:
assigning an environmental value to (or sensitivity of) a resource or receptor
(e.g. a protected species or designated site);
assigning a level of impact or effect; and
assigning a level of significance.
48. The significance of the effect, in broad terms, is usually determined by a
combination of the value of the receptor being affected and the magnitude or
level of the effect. This is reflected in a five point scale – Negligible, Minor,
Moderate, Major, Substantial – whereby material effects (i.e. those that are, or
may be, key decision making issues) are those where the significance of the
effect is ‘moderate’ or greater. Thus, a Minor effect will not be a significant
effect in EIA terms, whereas a Moderate effect may be, and a Major effect
almost certainly will be.
14 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
8. National Policy Context 49. As noted in Section 4 above of this NTS, the Scheme falls within the thresholds
for NSIPs, which are defined by the Planning Act. The energy National Policy
Statements (NPS’s) set out national policy against which proposals for major
energy projects will be examined by PINS and the Secretary of State, when
deciding the outcome of DCO applications.
50. The NPSs which are relevant to the DCO application are the:
Overarching NPS for Energy (EN-1); and
NPS for Fossil Fuel Electricity Generating Infrastructure (EN-2).
9. Habitats Regulations Assessment 51. In accordance with the Scoping Opinion issued by PINS an HRA has been
undertaken of the Scheme to assess the potential effects on the conservation
status of those European designated sites closest to the Scheme, namely the
Pembrokeshire Marine Special Area of Conservation (SAC), the Pembrokeshire
Bat Sites and Bosherston Lake SAC and the Cleddau Rivers SAC, together with
those further afield; namely the Castlemartin Coast Special Protection Area
(SPA), the Limestone Coast of South West Wales SAC and the Skokholm and
Skomer SPA.
52. The HRA is included as part of the DCO application documentation and has
been prepared in parallel with the EIA; it is however the subject of a separate
report.
10. Ground Conditions and Hydrogeology 53. The assessment of ground conditions and hydrogeology (the occurrence and
distribution of, and effects on underground or ground water) comprised a desk-
based review of the site history, geology, and hydrogeology of the Application
Site and the surrounding area, and a review of a comprehensive existing
groundwater chemical and physical dataset.
15 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
54. The underlying ground and groundwater conditions have been shown not to
present a significant risk to human health or controlled water receptors. With
the proposed mitigation measures in place most of the effects on receptors are
considered to be Negligible.
55. However, it is recognised that provision must be made for unforeseen situations
and the fact that the inevitable disturbance of land associated with construction
can lead to changes that may affect the way in which contaminants interact with
the environment. A Code of Construction Practice and a Construction
Environmental Management Plan (CEMP) will be in place to control the risks of
encountering and managing unexpected and unidentified contamination during
construction, including minimising risks to construction workers and
environmental receptors. The mobilisation and/or migration of existing
contaminated soil and groundwater, and the storage and use of potentially
contaminated substances are considered to have a Moderate adverse effect.
11. Hydrology, Water Quality and Flood Risk 56. An assessment of the baseline conditions in relation to hydrology has
demonstrated that the Application Site is at little to no risk from flooding. During
construction and operation, the flood risk posed to the Application Site has been
assessed as Negligible/Minor taking into account the adoption of appropriate
mitigation measures.
57. The flood risk posed by the Application Site will be mitigated by a range of
proposed surface water drainage techniques that will ensure run-off from the
Application Site is discharged at the existing rate despite an increase in
impermeable surfaces. This is achieved by design of a drainage system and the
inclusion of a primary and secondary basin capable of conveying and storing
flood water to maintain existing drainage rates from the Main CHP Plant Site.
The smaller secondary drainage basin allows temporary bypass of the primary
basin to be undertaken during fire-fighting or pollution incidents to maintain flood
alleviation during co-incident storm events.
16 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
58. There are unlikely to be any significant effects on hydrological conditions during
the construction phase. Activities on the Application Site will be controlled
through best practice site management practices including pollution prevention
and response plans, use of settling tanks or ponds to remove sediment and use
of temporary interceptors to remove oils, which will be implemented through the
CEMP. Effects will be temporary and are anticipated to be either Negligible or
Minor, neither of which are significant in EIA terms.
59. Potential impacts on water quality will be monitored to ensure mechanisms put
in place via the CEMP are effective and mitigate any impacts.
60. During operation, potentially polluting activities on site will be controlled through
site management practices under the environmental permit (EP) that will be
obtained from NRW as part of the separate consent to operate procedure. The
effect on the hydrology is considered to be Negligible to Minor, taking into
account the adoption of appropriate on site management, discharge limits set as
part of the EP and sustainable drainage techniques incorporated as part of the
drainage strategy, i.e. storm water basins.
61. Effluent discharges are anticipated to discharge certain substances (e.g. trace
amounts of heavy metals) into the Waterway at concentrations above relevant
environmental quality standard concentrations. Dilution and dispersion
modelling of this discharge plume shows the impacts to be of limited size and
duration, close to the outfall location. It was concluded such impacts are
negligible in EIA terms. Discharges will be controlled via the EP to prevent
pollution of the Waterway.
62. Effects during decommissioning will be dependent on the approach to
decommissioning and the extent of restoration considered appropriate for the
Application Site. Some beneficial effects are possible in the event that the
developed footprint is fully restored. Effects arising from the decommissioning
of the CHP Plant will be controlled through implementation of a CEMP.
17 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
12. Seascape, Landscape and Visual
Resources 63. The Seascape, Landscape and Visual Impact Assessment (SLVIA) considers
the potential effects of the CHP Plant on seascape and landscape character and
representative visual receptors. Since the Scheme will be lit, the SLVIA
considers effects during the daytime and at night. It has been prepared based
on best practice guidance and the methodology and scope of the assessment
has been subject to consultation with the Countryside Council for Wales (CCW,
since April 2013 NRW), PCNPA and PCC.
64. In Wales the key characteristics of seascape and landscape character areas
have been identified in studies undertaken on behalf of CCW and the effects of
developments on seascape and landscape character are assessed against
those characteristics. On land the principal reference documents are the CCW
LANDMAP and the Landscape Character Assessment of the Pembrokeshire
Coast National Park published in 2007. Reference is made also to ‘The
Register of Landscapes of Historic Interest in Wales’. Information contained
within the LANDMAP data base has provided a basis for the assessment
together with additional desktop and field studies. 28 individual landscape
character types derived from five ‘aspect’ layers – visual and sensory, historic
landscape, cultural landscape, geological landscape, and landscape habitats -
have been identified as being potentially affected by the Scheme.
65. The Application Site is located on the north shore of the natural harbour of the
Waterway, west of Milford Haven town. The plateau shaped peninsula of South
Hook Point lies mainly at 35 to 40m AOD, forming a prominent location within
this seascape context which lies partially within the PCNP. The village of
Herbrandston and the suburbs of Hakin and Hubberston on the fringes of Milford
Haven form the closest settlements to the site. The landscape/seascape
context to the west is an attractive seascape of high scenic value within the
PCNP. The landscape/townscape context to the east is dominated by large
scale energy and petrochemical installations which cluster around the shores of
18 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
the Waterway. The key feature of the CHP Plant for the SLVIA is its stack which
is recommended to be 75m in height but has been assessed for visual effects at
85m above ground level, in accordance with the design parameters, as a worst
case (see Sections 22 and 36 of this NTS).
Summary of Construction Effects on LANDMAP Aspect
Areas
66. Five landscape aspect areas will experience direct effects during the
construction phase of the Scheme. The effects will range from Minor to
Negligible in the day and at night and will all be medium term in duration. These
effects will not be significant in terms of the EIA Regulations 2009, either
individually or collectively.
67. The 81 aspect areas which lie either adjacent to, near or are distant from the
Application Site will experience indirect effects on character. The nature of
these effects will be adverse in the medium term for 58 of these receptors which
will experience a Negligible effect in the day and at night. Another 21 receptors
will experience indirect adverse effects of a Minor significance in the day and at
night. The remaining two aspect areas will experience Moderate effects in the
day and at night. These effects are not significant in EIA terms.
Summary of Visual Effects during Construction
68. Of the 22 viewpoints assessed, the receptor at the nearest viewpoint on the
Coastal Path at South Hook will experience Major effects during the day, which
will be significant in EIA terms. Moderate effects will be experienced by this
receptor at night. Moderate effects will be experienced during the day also at
two near receptors (Herbrandston and Upper Neeston) and one mid-distance
receptor (Great Castle Head). Four mid-distance receptors and three distant
receptors will experience Minor effects in the day and at night. Two near, five
mid-distance and three distant receptors will experience Negligible effects in the
day and at night.
19 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
69. Walkers using the Coastal Path will experience Moderate to Major effects
between Watch House Point and South Hook which will be a significant
sequential effect. Effects on mid to long distance views from other sections of
the Coastal Path will be Minor or Negligible, which is not significant.
Summary of Operational Effects on Seascape Character
70. The CHP Plant will be placed in the central industrialised section of the
Waterway within the Milford Haven seascape character unit. There would be no
loss of important characteristics within the unit, whilst the scale of the proposals
will have some influence over the wilder, undeveloped parts of the seascape.
The direct effects on character will be Moderate, which is not significant in EIA
terms.
Summary of Operational Effects on LANDMAP Aspect
Areas
71. Five landscape aspect areas will experience direct effects during the operational
phase of the Scheme. The effects will range from Minor to Negligible in the day
and at night and will all be medium term in duration. These effects will not be
significant in terms of the EIA Regulations 2009 either individually or collectively.
72. The 81 aspect areas which lie either adjacent to, near or are distant from the
Application Site will experience indirect effects on character. The nature of
these effects will be adverse in the medium term for 56 of these receptors which
will experience a Negligible effect in the day and at night. Another 21 receptors
will experience indirect adverse effects of a Minor significance in the day and at
night. The remaining four aspect areas will experience Moderate effects in the
day and at night. These effects are not significant in EIA terms.
Summary of Operational Effects on the Pembrokeshire
Coast National Park
73. The direct effect of the further development of the Application Site, which
predominantly lies within the PCNP, will not result in a significant effect on the
20 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
special qualities or purpose for designation of the Pembrokeshire Coast National
Park and will not result in the loss of any important features, elements or
characteristics. The dramatic juxtaposition of large scale industrial installations
and wild seascape is typical of the Waterway and will not be compromised by
the development. The sympathetically designed buildings and structures within
the CHP Plant will limit any adverse effects on the national park due to an
intensification of development at South Hook Point.
Summary of Visual Effects during Operation
74. Of the 22 viewpoints assessed for the operational scheme, receptors at three
near viewpoints will experience Major effects in the day and Moderate effects at
night (South Hook, Herbrandston and Upper Neeston). One receptor (Great
Castle Head) in a mid-distance location will experience Moderate effects during
the day and Minor effects at night. Receptors at 15 mid-distance viewpoints will
experience Minor effects in the daytime and at night. Two receptors at distant
viewpoints will experience Negligible effects in the day and at night.
75. Walkers using the Pembrokeshire Coast Path National Trail will experience
Moderate to Major sequential effects between Watch House Point and South
Hook Point which will be a significant sequential effect. Effects on mid to long
distance views from other sections of the path will be Moderate to Negligible,
which is not significant. Sequential effects on occupiers of vessels within the
Waterway will range from near to long distance in nature and range in
significance from Moderate to Minor, which is not significant in EIA terms.
Summary of Cumulative Zones of Theoretical Visibility
76. The combined Zones of Theoretical Visibility (ZTVs) for the five major industrial
sites (Murco Refinery, Valero Refinery, Dragon LNG Terminal, Pembroke Power
Station, the LNG Terminal) which exist in the vicinity of Milford Haven will result
in a visual receptor at any point within the ZTV for the proposed CHP Plant
always being able to see at least one group of stacks within the landscape. This
emphasizes the importance of industrial development as a feature within the
landscape and seascape of Pembrokeshire. The expectation of the visual
21 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
receptor within the study area is that they will see large scale industrial
infrastructure as prominent and sometime dominant features in the vicinity of
Milford Haven. The proposed CHP Plant will be visible, but not uncharacteristic,
in this established context.
13. Terrestrial Ecology 77. There are three international designations found within a 10km radius of the
Application Site (Limestone Cliffs of South West Wales SAC, Pembrokeshire
Marine SAC and the Castlemartin Coast SPA) and three further internationally
designated sites within 15km (see Figure NTS 3). A nationally designated site
lies within 2km of the Application Site, the Milford Haven Waterway SSSI.
78. The Main CHP Plant Site comprises naturally recolonising areas surfaced with
crushed stone characterised by early successional plant communities.
79. Other biodiversity interests on the wider LNG Terminal site include the Nature
Conservation Area (NCA). A mosaic of grassland, scrub and wetland habitats in
the NCA support a diversity of flora and fauna and the assemblage species
have nature conservation interest in a county context.
80. Greater horseshoe (GHS) bats roost in the South Hook Fort and associated gun
emplacements throughout the year. Numbers of bats reach nationally important
levels in winter and regional importance in summer.
81. The main GHS bat flight paths lie outside the LNG Terminal with only low level
commuting by greater horseshoe bats within the NCA. Common pipistrelle and
soprano pipistrelle were the main bat species recorded but activity levels across
the LNG Terminal site, excluding the NCA and skim pond, were negligible.
82. A series of measures have been designed for each phase of the Scheme to
protect the value of the noted ecological receptors. The principles of noise
abatement, lighting design, dust suppression, and pollution prevention are
integrated into the Scheme. Existing measures which minimise access into the
NCA will be extended to include all the construction and operational staff
involved in the Scheme.
22 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
83. Direct impacts will result from both permanent and temporary habitat loss. A
population of an uncommon plant species in Pembrokeshire occurs in the Main
CHP Plant Site and will be unavoidably impacted.
The permanent loss of habitat for the Main CHP Plant Site and temporary loss
of habitat associated with the construction phase will be of Minor significance,
however this is not significant in EIA terms.
84. The Main CHP Plant Site and wider Application Site have low value for
protected species although localised areas have the potential to support reptiles.
In line with legislative obligations, measures will be taken to avoid the killing or
injury of animals during construction activities through the implementation of
advance protection measures.
85. There are potential indirect impacts on habitats adjacent to the Main CHP Plant
Site and the faunal species using them. Potential impacts on the section of the
NCA directly adjoining the Main CHP Plant Site will be expected to have
Negligible significance for biodiversity.
86. The assessment has concluded that the designed in mitigation measures
including the CEMP are sufficient to avoid or control impacts on GHS bat roosts
or foraging during construction.
87. The behaviour of mobile species using the NCA, including breeding birds, will
probably be affected during construction but the significance of the effect should
not be greater than Minor, which is not significant in EIA terms. Wintering bird
activity on the eastern side of the NCA during the construction period may also
experience a Minor effect which would be localised to the area of the LNG
Terminal.
88. The air emission modelling has shown that the modelled nitrogen deposition and
acidification on terrestrial habitats in Milford Haven Waterway SSSI within 2km
of the emission point falls below 1% of the relevant environmental quality
standard and will not be significant.
89. The grassland mosaic within the NCA will also be subject to increased air
emissions although the modelled levels of acidification and nitrogen deposition
23 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
will not be sufficient to change vegetation structure or composition or alter the
status of habitats in the NCA.
90. At worst the significance of the effect of the Scheme on the summer GHS roost
could be Minor, while there will be no impact, and thus no effect, on the
hibernation roost.
91. There will be a change in the context of the eastern boundary of the NCA due to
the operation of the CHP Plant but a sensitive lighting plan will be implemented
to prevent a reduction in quality of the habitats for greater horseshoe bats,
breeding birds and wintering birds. For each of these receptors, the significance
of effect will be no greater than Minor which is not significant in EIA terms.
92. The potential impacts that could arise during the decommissioning phase of the
Scheme will be similar to those identified during construction but of a shorter
duration. No impacts with a significance of effect of greater than Minor are
predicted from the available information.
93. There are no other known permitted or proposed developments in close
proximity to the LNG Terminal through which cumulative impacts could arise on
terrestrial habitats.
94. In summary, the effect on many faunal groups (including bat species) will have
potential ecological significance of no greater than Minor, which is not significant
in EIA terms. The effect on dittander species (a rare plant of county importance)
will be Moderate adverse, which is significant in EIA terms.
14. Marine Environment and Ecology 95. The potential impacts and subsequent effects associated with the Scheme have
been assessed in relation to the marine environment. In terms of impacts
associated with the construction and decommissioning phases these are
considered to be limited as no construction will be undertaken within the marine
environment and there will be no net change in surface water discharge at the
relevant discharge point. Thus, the marine ecological assessment focused
24 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
principally on the operational impacts as a result of integrating the CHP Plant
with the LNG Terminal.
96. The outputs of aqueous modelling with regard to the mass balance equation for
nitrate, has shown that there will be an overall reduction in nitrate concentration
and mass in the combined process waste water discharge at the relevant
discharge point. In addition, the results of the aerial emissions modelling for the
nitrogen mass balance assessment has shown that there will be a decrease in
nitrous oxide (NOx) concentrations and decrease in nitrogen deposition at all
marine sites following integration of the CHP Plant and LNG Terminal.
Consequently no further assessment was undertaken on the effects of aerial
emissions on the marine environment.
97. As a result, the marine ecological assessment focused on the potential change
that may occur for various process waste water parameters (i.e. temperature,
metals (copper, nickel, zinc and lead), chlorine and ammonia) in the discharge
following integration of the CHP Plant with the LNG Terminal. The results of
that assessment indicate that, for most impacts, the subsequent effects on the
marine ecology are predicted to be no greater than of Minor significance, which
will not be significant in EIA terms.
98. In terms of cumulative effects for the most part there will be no significant
adverse effects as a result of constructing and operating the CHP Plant with
other projects. In terms of additive effects from dredging projects, these are
considered to be limited as dredging occurs over short time frames and over
relatively small discrete areas sufficiently far apart that there is no spatial
overlap. Consequently, it is unlikely to lead to an adverse additive effect on the
marine environment.
99. In terms of the high level assessment for the grid connection options (being a
trenched solution or a tunnel to cross the Waterway) alone and cumulatively, for
the majority of impacts, with the implementation of suitable mitigation measures,
the effects are considered to be Minor, which is not significant in EIA terms.
There is some uncertainty with regard to type of subtidal habitat present along
the potential grid connection corridors if a trenching option is utilised, and
25 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
therefore the potential effects. Prior to the submission of the relevant grid
connection applications (where necessary) further surveys will be undertaken to
determine the habitat, extent and health of the communities present to quantify
the impact more precisely.
15. Air Quality 100. The air quality assessment has considered nuisance dust effects during the
construction phase of the Scheme and the air quality effects due to the
operation of the Scheme.
101. A risk assessment of construction-related effects has been undertaken based on
the Institute of Air Quality Management guidance. Given the rural setting,
distance from receptors and assuming good practice controls during the
construction phase, dust impacts are forecast to be Negligible.
102. Detailed atmospheric dispersion modelling has been undertaken for the first
year in which the Scheme is expected to be fully operational, 2017. Predicted
environmental concentrations of pollutants are forecast to be well below the
relevant objectives at receptors. Changes in pollutant concentrations
associated with the operation of the Scheme at existing receptors are not
expected to be significant, with slight improvements in pollution concentrations
forecast for many receptor locations for the pollutants assessed, when
compared with the current process contributions from the 15 existing SCVs.
The overall significance of effects is considered to be Minor.
103. In conclusion, the potential worst case effects on air quality will not represent a
constraint to the Scheme.
16. Noise and Vibration 104. The assessment considered the potential for noise and vibration effects on
Noise Sensitive Receptors as a result of the Scheme.
105. Baseline noise conditions were established through noise surveys carried out at
representative locations near to the Application Site.
26 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
106. The assessment demonstrates that, during the construction phase of the
Scheme, there is a potential for adverse noise effects at some residential
properties, although this is dependent on the levels of mitigation, construction
techniques and location of works.
107. A small number of residential properties may experience a Minor effect due to
normal operation of the CHP Plant but it is anticipated that these effects will be
reduced or eliminated during the detailed engineering design process for the
Scheme.
108. Noise from commissioning of the CHP Plant and when it is operating in
independent mode will also potentially equal or exceed the representative
background noise level at a small number of nearby locations, resulting in a
Minor effect. However, due to the infrequent and temporary nature of these
activities, it is not considered that this will constitute a significant effect.
109. There will be no significant vibration effects associated with the construction or
operational phases of the Scheme.
110. There will be no significant noise effects on recreational amenity in the area, i.e.
along the Coastal Path.
111. The effects of noise (including ultrasound) on ecological receptors has been
considered also and noise levels have been predicted for the NCA adjacent to
the Main CHP Plant Site. It is considered that noise emitted during the
operational phase of the Scheme is unlikely to have an adverse ecological
effect. Any further measures designed to control noise emissions to protect
residential receptors will also serve to reduce noise levels at ecologically
sensitive locations.
112. On the basis of the above, it is considered that with the proposed mitigation,
noise levels from the Scheme will be appropriately controlled using Best
Available Techniques.
27 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
17. Historic Environment 113. The assessment of the historic environment has identified the potential for the
proposed Scheme to result in Moderate or possibly Major effects on buried
archaeological remains in one clearly identified location to the north of the Main
CHP Plant Site. Such effects will occur during construction and will be direct
and permanent.
114. Any such effects will be offset through a programme of archaeological
investigation within that part of the land required for the Scheme where a high
potential for the presence of archaeological remains has been identified. This
programme will be agreed with the relevant authorities prior to commencement
of any work in this area.
115. There will also be a Moderate reversible effect on the Scheduled Monument and
Grade II* listed building of South Hook Fort as a result of changes within its
setting.
116. All other effects on historic environment resources will be Minor or Negligible,
and fully reversible following decommissioning. This includes a Minor effect on
the registered Milford Haven Waterway Landscape of Outstanding Historic
Interest.
18. Traffic and Transport 117. The construction, operational and decommissioning transport impacts of the
Scheme have been assessed in accordance with the Institute of Environmental
Management and Assessment (IEMA) guidance entitled ‘Guidelines for the
Environmental Assessment of Road Traffic’ (Institute of Environmental
Assessment 1993)
118. The maximum number of vehicle movements generated during the peak
construction phase of the Scheme over a one day period is estimated at 996
two-way movements per day, 80 of which will be HGV movements.
28 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
119. Construction staff have been assumed to arrive at the Application Site between
07:00 and 08:00 and depart between 18:00 and 19:00 and have been assessed
on this basis. In reality, the construction staff will have staggered working hours
and their movements will be spread over longer than a one hour period. Such
an assumption creates a concentrated mass movement of construction staff and
thus a robust theoretical assessment.
120. Construction HGVs will generally be routed to and from the Application Site
along the A4076, although it is also possible that HGVs will travel directly to and
from a local quarry with rock and associated material. In order to create a
robust assessment, two scenarios have therefore been created, one that
assumes all construction HGVs are routed to and from the Application Site via
the A4076 and a second that assumes that they are routed to and from Bolton
Hill Quarry via Tiers Cross Road.
121. The assessments undertaken have predicted that the peak construction period
will increase daily (12 hour) total traffic flows by a maximum of 39.5% and daily
(12 hour) HGV flows by a maximum of 53.3% on Dale Road (east of Application
Site access).
122. The environmental impact assessment undertaken establishes that the traffic
increases during the peak construction period for the Scheme are unlikely to
create any non-Negligible effects upon the highway network. The assessment
undertaken demonstrates that during the peak construction phase for the
Scheme there will be no significant impact in relation to visual effect, severance,
driver delay, pedestrian delay, pedestrian amenity, accidents and safety,
hazardous loads or dust and dirt.
123. Traffic flows generated by the operational CHP Plant are predicted to be
substantially lower than those during the construction phase. The traffic flows
generated during this phase will not exceed the thresholds set out in the IEMA
Guidance which indicates such increases will not be perceptible and a full
assessment of the impact upon visual effects, severance, driver delay,
pedestrian delay, pedestrian amenity, accidents and safety, hazardous loads
and dust and dirt is not necessary.
29 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
124. The traffic generated during the decommissioning phase of the Scheme will be
less or similar to the construction phase. There will therefore be no significant
impact upon visual effect, severance, driver delay, pedestrian delay, pedestrian
amenity, accidents and safety, hazardous loads or dust and dirt during the
construction, operational or decommissioning phases of the Scheme.
125. It is therefore considered that in terms of traffic and transport there are no
significant environmental effects as a result of the Scheme.
19. Socio economics 126. There are two strands to the socio-economic assessment, the first of which
concerns the economic effects of the Scheme in terms of the direct provision of
employment during its construction and operational phases. The second strand
concerns the potential effects of the Scheme on recreation and tourism in the
area.
127. In the case of the first strand, data to establish the baseline economic conditions
in Pembrokeshire and the adjacent counties of Carmarthenshire and Ceredigion
were obtained from both the 2011 Census and 2001 Census data as well as
from sources such as NOMIS Labour Market Profiles and the StatsWales
section of the Welsh Government website. For recreation and tourism,
information was gathered mainly from Ordnance Survey maps and local
authority websites.
128. The census and other data show that economic conditions in the three counties
in general are relatively healthy with above (Welsh) average health indicators,
car ownership, levels of skilled workers and less than (Welsh) average levels of
unemployment. The 2011 Indices of Multiple Deprivation and the latest
research by Sheffield Hallam University (September 2012) both confirm this
picture. However, all three counties have earnings below the Welsh average
129. In addition to the above, Pembrokeshire has above (Welsh) average economic
activity, job density and levels of qualifications.
30 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
130. The Coastal Path runs in close proximity to the Application Site but it is a long,
linear facility extending to 299km with only a small part providing views of the
proposed CHP Plant. The main opportunities for outdoor recreation are found
elsewhere in the PCNP and the county of Pembrokeshire, and the principal
visitor attractions of Pembrokeshire are mainly located some distance away
from the Milford Haven area. The overall impact of the Scheme on tourism and
recreation in Pembrokeshire is therefore, considered to be Neutral.
131. The Scheme is likely to provide several hundred construction jobs on average
during the 26-30 month construction period and around 30 permanent jobs
when complete and in operation. This will be of benefit to the local economy
and this benefit is increased when the multiplier effect is taken into account in
relation to indirect and induced employment.
20. Cumulative Assessment 132. The cumulative assessment of the Scheme with other major developments,
either in construction or in the planning system, identified the following projects
for assessment.
Wind Farms (onshore and offshore)
Atlantic Array Offshore Wind Farm in the Bristol Channel;
Single wind turbine (48m hub height) at Sandy Haven (St. Ishmaels);
Single wind turbine (48m hub height) at Amroth, Narbeth;
Single wind turbine (37m hub height) at Amroth, Narbeth; and
Single wind turbine (35m hub height) at Pelcomb Bridge, Haverfordwest.
133. The cumulative assessment concluded that, with the exception of the proposed
single turbine at Sandy Haven, their effects on the LANDMAP Landscape
Character aspects will be either Negligible or Minor, neither of which are
significant in EIA terms. In respect of visual impacts the significance of the
cumulative effects will be no greater than the significance of effect with the
Scheme alone.
31 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
Marine Environment
Aqueous discharge from the LNG Terminal;
Potential grid connection options for the Scheme;
Current dredge areas (with the nearest dredged area occurring at a distance
of 1.1km from South Hook Jetty and extending out to a distance of 9.55km);
Possible future dredge/development areas (with the nearest located at a
distance of 1.5km);
Aqueous discharges (the nearest being Pembroke Power Station which is
located at distance of 5.7km);
Aerial emissions (the nearest stack being located at a distance of 1 km from
the Application Site); and
Renewable projects (the nearest being located at a distance of 7.3 km).
134. All of the above projects affecting the marine environment, with the exception of
the aqueous discharge from the LNG Terminal and the potential grid connection
options for the Scheme, have been screened out in terms of individual impacts,
as there will be no spatial overlap with the modelled discharge plume for the
Scheme and therefore no synergistic effects or the projects are already built and
operational and therefore any potential effect will already be included in the
baseline information gathered as part of this assessment.
135. The current aqueous discharge from the LNG Terminal is a component part of
the overall marine assessment and therefore this has been included as part of
the assessment of the four operating modes under the Scheme.
136. The potential grid connection for the Scheme between the Main CHP Plant Site
and National Grid Electricity Transmission plc’s sub-station at Pembroke Power
Station (the Pembroke Sub-station) is at an early stage of definition. Two
options are currently under consideration. The first of these is a utility tunnel
between the Application Site and the Popton area which will be located beneath
the Waterway with onward cable trenching to the Pembroke Sub-station. The
32 South Hook CHP Non Technical Summary Document 1.3.4 May 2013
second of these is a cable trenching corridor from the Application Site across
the Waterway to the Popton area, again with onward cable trenching to the
Pembroke Sub-station. Given the likely tunneling techniques that will be
employed on the first option, no cumulative effects are anticipated on the marine
environment of the Waterway and any cumulative effects of the terrestrial
cabling component are anticipated to be of no more than Minor significance.
137. Similarly for the second option, given the known extent of the marine habitats
present and the cabling techniques available the cumulative assessment
predicts that the effects will be no greater than Minor, which will not be
significant in EIA terms.
