1.0 Introduction
1.1 Neath Port Talbot County Borough Council (NPTCBC) has requested
that Tata Steel UK Ltd (Tata Steel) commit to an agreed set of
overarching design principles to guide the final design of the proposed
development (the proposed development) authorised by the Port Talbot
Steelworks (Power Generation Enhancement) Order (the DCO). The
request was made through NPTCBC’s Written Representations and
Local Impact Report (LIR) submitted during the Examination of the DCO.
1.2 Tata Steel is committed to positively impacting the communities in which
it operates and respecting the environment. The company adopts a set
of 5 values, the third of which is 'Responsibility'. This includes acting
responsibly towards the environment and the community reflected in a
commitment to good design to ensure that its operational sites make a
positive and lasting contribution to the communities within which they sit.
1.3 This Design Principles Document (DPD) has been prepared to provide
the commitment to high quality design requested by NTPCBC in relation
to the proposed development. The design of the buildings forming part
of the proposed development authorised by the DCO will reflect the
principles set out in this DPD. The DPD will be a certified document
under article 24(1)(e) of the DCO.
1.4 Requirement 4 of Schedule 2 to the DCO establishes the parameters for
the proposed development, and requires that the final design submitted
to NPTCBC for approval complies with the DPD. This provides an
appropriate framework to ensure a high quality design can be achieved
for the proposed development within the parameters established by
Requirement 4.

2.0 Context
2.1 The context to the DPD is provided by the key planning policy and
guidance relating to the design of energy generating projects, including
the relevant parts of Planning Policy Wales and TAN 12: Design (2014)
and the matters raised by NPTCBC in its submissions to the Examination
(which made reference to the Policies within the adopted Unitary
Development Plan and the emerging Local Development Plan).
Planning Policy on Design
2.2 Key to the assessment of the proposed DCO is NPS EN-1 (Overarching
National Policy Statement for Energy). Of particular relevance is Section
4.5, which provides criteria for “good design” for energy infrastructure.
2.3 Paragraph 4.5.1 of NPS EN-1 acknowledges that visual appearance is
an important factor in good design, but the concept goes beyond
aesthetic considerations. Importance is firstly placed upon “the
functionality of an object…including fitness for purpose and
sustainability.” Some of the key principles of good design for energy
projects highlighted in the paragraph are listed below:
• Sustainable infrastructure
• Sensitive to place
• Efficient use of natural resources and energy in construction and
operation
• An appearance that demonstrates good aesthetics as far as
possible
2.4 The NPS acknowledges that the functional nature of energy
infrastructure can limit the contribution such schemes can make to the
quality of an area.

2.5 Paragraph 4.5.3 of NPS EN-1 describes how the Secretary of State
(SoS) should be satisfied that proposed energy generation infrastructure
has “taken into account both functionality (including fitness for purpose
and sustainability) and aesthetics (including its contribution to the quality
of the area in which it would be located) as far as possible.” Energy
infrastructure projects should be “as attractive, durable and adaptable…
as they can be”.
2.6 Planning Policy Wales sets out the Welsh Government’s land use
planning policy in respect of ‘Promoting sustainability through good
design’ and ‘Planning for Sustainable Buildings’, and TAN 12: Design
(2014) provides advice on how this can be facilitated through the
planning system. Tata Steel accepts that the objectives of PPW and
TAN12 must be considered alongside NPS EN-1.
NPTCBC Design Objectives
2.7 NPTCBC’s Local Impact Report (LIR) includes commentary on “The
Design of the Buildings” (a sub-section of LIR Section 7.3 – Landscape
and Visual Impact). In this section, NPTCBC describes the importance of
the area as a gateway into Port Talbot, as it is adjacent to the new
Harbour Way PDR and close to the Harbourside Strategic Regeneration
Area and the town centre. Furthermore, LIR paragraph 7.3.8 describes
how the re-cladding of the main strip mills and the landscaping
associated with the PDR have significantly improved the area. In LIR
paragraph 7.3.14, NPTCBC states that the power station has the
potential to become a key landmark building and enhance this area of the
steel works.
2.8 LIR paragraph 7.3.11 acknowledges that the detailed design of the power
plant is an iterative process. However, NPTCBC consider “that the
applicants should be required to further develop the design in order to
adequately demonstrate their commitment to the development of a high
quality, bespoke design which exceeds the current relatively standard
The Port Talbot Steelworks (Power Generation Enhancement) Order Design Principles Document DPD1.01

design submitted with the application.” LIR Paragraph 7.3.12 states that
they believe this information should be submitted at this stage to allow “a
greater degree of certainty that the development will be of the highest
design quality; and secondly, to ensure that the parameters within the
draft DCO are adequate to allow for any variation (in particular in height)
which may be necessary for any additional design ‘elements’ (over and
above, for example, the height of the turbine hall, boiler house etc.)”
2.9 LIR paragraph 7.3.13 states that the Applicant and NPTCBC are in
discussion with the applicant with regard to the above matters and are
seeking agreement as to how the applicant can provided the authority
with the certainty they require.
2.10 This DPD reflects the outcome of those discussions and therefore both
the objectives of NPTCBC and the acknowledged guidance on design in
the context of energy infrastructure. The design principles set out in the
DPD have been informed through dialogue between Tata Steel and
NPTCBC.

3.0 Design Principles
Overarching Principles
3.1 Section 4.3 of the Design and Access Statement (DAS) submitted with
the DCO application presents the design principles established for the
proposed development. By adding the further over-arching design
principles set out below, this document intends to supplement the
provisions of the DAS and respond to both the points raised by NPTCBC
and the relevant planning policy found in Section 4.5 of NPS EN-1.
3.2 The over-arching design principles for the proposed development are (in
no specific order) as follows:
a) Functional and Operable – The power station must be
designed in order to maximise its functionality. The seeking of
attractive, external aesthetics should not hinder the way in which
the power station is operated.
b) Sustainable – The design of the power station will actively seek
to reduce the environmental impacts arising from its construction
and operation.
c) Safe – The safety of the power station will be maximised through
security provisions, functional lighting and designing out crime.
d) Prominence & Aesthetics – The final design of the power
station will seek to achieve a level of quality which reflects the
site’s prominence next to the PDR and its ‘gateway’ position.
This could be achieved through a range of design techniques, for
example, varied elevation treatments, colour palettes and
materials, which allow the building’s inherent functionality to be
maintained.
The Port Talbot Steelworks (Power Generation Enhancement) Order Design Principles Document DPD1.01
April 2015 7
e) Sensitive to Context – The power station must take account of
its surrounding area in terms of the immediate urban context and
the wider landscape. This includes both its ‘gateway’ location
into the town and position within the wider steel works.
f) Creates Visual Interest – Positive public perception will be
achieved through the quality of design of the proposed
development.
g) Area Regeneration – The final design of the power station will
adopt methods (where possible) to contribute to the physical and
economic regeneration of the area.
h) Encompassing the Natural Environment – The use of soft
landscaping will be maximised where safety and operational
considerations allow. Effort will be made to ensure that
improvements to the area made through the Harbour Way project
are enhanced and not undermined.
i) Maintainable and Durable – The materials used to construct the
buildings must be durable, resistant to adverse weather and
change over time, and easily maintainable.
j) Appropriate Materials – As well as being durable and
maintainable, the materials used will respond to local context and
the character of the area.
k) Adaptable – The design will be adaptable to allow for future
operational flexibility and changing functional requirements.
l) Value for Money – viability will be a key consideration in the
design process and careful consideration will be given to ensure
a viable balance between the long-term costs of operating the
power station and its fitness for purpose is achieved.

m) Buildable – The design will have integrated build ability and will
reflect construction requirements.
n) Locally Informed – Where appropriate, engagement with the
local community will be maximised and thoroughly utilised to
inform the final design of the buildings. This will be an iterative
process.
Tata Design Commitment
3.3 This section builds on the overarching design principles set out above
and provides more detailed information and examples on how these can
be translated into built form.
3.4 Tata Steel is committed to positively impacting the communities in which
it operates and respecting the environment. This commitment is
reflected in the recent development at the steelworks in Port Talbot,
much of which has been praised for its design quality. Examples of what
has been achieved at Port Talbot are set out below to demonstrate the
quality that the design principles set out above can deliver.
3.5 Tata Steel has its own internal standards for building design. The
proposed development will be subject to these standards. Of these,
Mandatory Engineering Standard (MES) 002 relates to the “Specification
for limiting noise from plant and equipment”. MES002 includes
standards that are consistent with BS4142 (2014) and it is expected that
these will be reflected in the terms of the Environmental Permit for the
proposed development.

3.6 The developments highlighted above are all located to the south of the
proposed location of the power station buildings along Harbour Way. As
well as the BREEAM ratings achieved, these buildings received the
following awards:
• Constructing Excellence in Wales Innovation Award 2013
• South Wales LABC Sustainability Award 2013
• CIBSE South Wales Sustainable Project of the Year 2012.
3.7 As well as the award-winning sustainability, Tata Steel has also adopted
modern and attractive design concepts with consistent finishes and
styles across all three buildings. Aesthetically pleasing features such as
set back panels, glass facades, thoughtful building envelope design and
sensitive landscaping have been used to ensure the standard of design
of new buildings at the steel works has been heightened. The proposed
development is situated in close proximity to these buildings and its final
design will reflect this.
3.8 The above developments demonstrate Tata Steel’s commitment to high-
quality, sustainable design. Tata Steel is committed to continuing this
legacy, which will be carried through in designing the proposed
development.
3.9 Tata Steel recognises that design is an iterative process and is
committed to delivering high quality design for the proposed
development. The cladding of the buildings will respond to landscaping
and context, while sensitive colour palettes, materials and design
techniques will be adopted. Tata Steel is fully committed to engaging
with NPTCBC when finalising the design of the buildings which form part
of the proposed development.

3.10 Tata Steel commits to working with NPTCBC in advance of the formal
submission to the Council of the detailed design of the proposed
development for approval under Requirement 4 of the DCO. Tata Steel
will also work with NPTCBC prior to the submission of an updated
Design and Access Statement to accompany the formal submission of
the detailed design, which shall reflect the advice and objectives within
TAN 12: Design (2014), demonstrate the iterative nature of the design
process following detailed appraisal of context, and provide evidence of
how the final design has regard to the national and local policy context in
section 2 and reflects the design principles outlined above.

CSP UK.ENGINEERING STANDARD
MES 002
Specification for LimitingNoise from Plant and
Equipment
When PRINTED this is an UNCONTROLLED copy
01.11.0211MES002DateRevisionIssuePage NumberReference
1 SCOPE
This standard specifies the requirements for limiting noise from all plant and equipmentsupplied to CSP UK Limited and is additional to any requirements under the Supply ofMachinery (Safety) Regulations 1992. The requirements of this standard are mandatory unless dispensation is given by theEngineering Director CSPUK.Where plant or equipment to be supplied cannot meet the noise requirements of the purchaser,the cost of noise control measures to ensure compliance with the agreed specification shall beprovided.
2 RESPONSIBILITIES
It is the responsibility of the purchaser to ensure that wherever manufacturers information issupplied under different terms or conditions that these are not accepted and the requirementsof this standard are contractual.
3 WORKPLACE NOISE
Plant or equipment installed on site should not increase existing noise levels and where there isan impulsive, tonal or intermittent noise component an additional 5 dB penalty below existingconditions shall be imposed. Particular care is required when equipment is to be installed inareas where noise levels are just below Corus' hearing protection limit of 85 dB(A), to ensurethat the final conditions are still below 85 dB(A).Plant or equipment supplied should normally be less than 85 dB(A) at 1 meter under normaloperating conditions to control workplace noise and help reduce personal noise exposures.Where significant tonal and/or impulsive elements are present a 5 dB penalty is appliedresulting in a requirement of 80 dB(A) at 1 meter. However it is recognised that many situationswill require a lower limit than this, particularly for the control of noise affecting localcommunities, see 6 below, in which case the maximum acceptable noise level will be specifiedby the purchaser at the enquiry stage. In some circumstances a higher noise level may be agreed where strict adherence to the 85dB(A) limit is unnecessary or where excessive costs would be incurred to little benefit in plantnoise levels or to personal noise exposures. An example of this could be the installation of anemergency standby diesel unit in an open or unmanned area.The adoption of noise levels higher than 85 dB(A) at 1 meter as the contractual limit must beagreed in writing with the CSP UK Health & Safety and Environmental departments, stating theacceptable noise level at 1m, prior to the order being raised.Where equipment is normally used in multiple units the stipulated noise level will be with thenormal number of machines in use.
4 AUDIBLE WARNING SIGNALS Alarm sirens, klaxons, fire alarms etc. are not covered by this standard. Specialist assessmentand selection is required when purchasing this type of equipment to ensure that alarms arecorrectly specified and are neither too loud nor too quiet for the situation.Guidance on selection of audible warning signals can be found in Corus P&PD 117 and inBritish & European standards
5 TANNOY SYSTEMSCare should be used when specifying tannoy systems to avoid systems which are either tooquiet or too loud for the area in question. Systems which are over loud for an area can increasepersonal noise exposures significantly.
Where tannoy systems are to sound outside of buildings or structures care must be taken toprevent community noise nuisance at night from site messages. Where high volumes arerequired for safety reasons, restriction in the use of the external systems at night to emergencyor essential messages only will need to be considered.

6 COMMUNITY NOISE
Plant or equipment installed on site should not increase noise levels beyond the site boundaryand where there is an impulsive, tonal or intermittent noise component an additional 5 dBpenalty below existing conditions shall be imposed.Noise during demolition, construction, and commissioning stages shall be controlled so as notto give rise to complaints. In situations where the generation of noise in the community isunavoidable and likely to give rise to complaints then this must be highlighted during the tenderstage to allow possible alternatives to be examined. Where alternatives are not practicable,time will be required to allow consultation with the regulating agencies and liaison with the localauthorities.Particular care is required when noise will be generated over weekends or at night.Plants authorised under IPPC legislation will require an environmental impact assessment forany equipment that could affect noise levels in the local communities around the site. Thisshould identify all the significant sources of noise associated with the equipment, the noisecontrol or reduction methods available and the BAT requirement for the installation. Particular attention should be given to non routine and emergency situations if there is thepotential for significant noise generation.
7 PLANT & EQUIPMENT NOISE DATA SHEET
The supplier will provide a data sheet listing all the sources of noise from the plant or equipmentand the associated A-weighted sound power levels (A-weighted sound pressure levels atspecified positions and/or octave band levels may also be necessary) that are guaranteed bythe supplier. Where projects involve numerous sources, as in a typical new plant installation, a site layoutidentifying the location of all the sources of noise will also be required.
8 USE OF MODELLING TECHNIQUES
The use of sophisticated noise modelling programmes can be used to demonstrate at tenderstage that equipment will meet the standard. However the sound power and spectrum of thesource(s) used in the programme must be those of the equipment under site operating and notmanufacturers test conditions. Measurements on similar equipment operating in other areascan be made to determine the sound power levels to be used in the model. Where modellingresults have been used to compare equipment and predict final noise levels, measurements willbe required after commissioning to confirm the results.
9 DEMONSTRATING COMPLIANCE IN THE WORKPLACE
Manufacturers information on noise levels can be used to compare equipment prior to order butmust not be used for demonstrating compliance with this standard. Unless the informationclearly states the sound power level of the equipment when in full operation, the figuresprovided by the manufacturer will not be the same as the noise from the equipment when it isactually in use in the workplace. The only way to demonstrate compliance with this standard is for an on site performance test tobe completed. The equipment should be tested over its full working range whilst performing the task it waspurchased for. Where equipment normally operates in multiple units the test will be carried outwith the requisite number of units in service.Where the plant or equipment is of cyclical operation the measurement time should cover aminimum of one full cycle.

01.11.02112MES002DateRevisionIssuePage NumberReference
10 DEMONSTRATING COMPLIANCE IN THE COMMUNITY
Community noise measurements taken when the wind speed is 3 m/s or less can be used todemonstrate compliance with this standard. The wind direction should generally be favourablefor the transmission of noise, i.e. from the source to the receiver (preferably within plus orminus 45 degrees) and measurement should be avoided if the temperature is below 3 deg C orduring rainfall.Due to the vagaries of the weather and the need for some plants to build up slowly to normaloperating levels, final acceptance testing could be several months after commissioning.
11 UNITS OF MEASURE
Sound Power dB(A)Sound Pressure dB(A) LeqPeak Pressure dB(C)Octave bands minimum 63 Hz to 8 kHz
Both the measurement position and measurement time must be specified for octave band andpressure measurements.
12 EQUIPMENT REQUIRED
Integrating sound level meters used for measurements should be a minimum of Class 2 andpreferably Class 1 and should meet the requirements of current standards.Both the meter and calibrator should have been tested within the last two years and a certificateissued showing that they meet the requirements of the standard.
