1.0 Introduction

1.1.1. An Environmental Statement (ES) has been prepared and submitted on behalf of the

Applicant and supports a Full Planning Application for access works at the Purfleet

Thames Terminal (the Terminal) within the borough of Thurrock in Essex.

1.1.2. The Proposed Development comprises the demolition of existing structures and

construction of a new roundabout and highway works at Stonehouse

Corner/London Road, a new secure site entrance and exit facilities, along with

landscaping, drainage and associated works.

1.1.3. The ES sets out the assessment of the likely environmental effects which may arise

as a result of the Proposed Development.

1.2. The Site

1.2.1. The Application Site (the Site) comprises of 5.13ha of land located within Purfleet

Terminal which is situated on the north bank of the River Thames, immediately to

the west of the Dartford Crossing. The Site location is shown on Figure 1.1.

(presented at the end of the NTS).

1.2.2. The Terminal has been owned by the Applicant, Purfleet Real Estate, and operated

by C.RO Ports London Ltd since 1992 as a roll-on roll-off freight terminal for the

handling, storage and on-carriage of trailers, containers, vehicles and general cargo.

1.2.3. The Site is industrial in character and covers an area of land predominantly in port

use for surface car storage. It also includes a short section of London Road; part of

Jurgens Road (private road); an existing landscape bund to the south of Jarrah

Cottages; a small part of the Tilbury Loop railway line; and a small area of scrub land

within the area known as Purfleet Farm.

1.2.4. The Site is bounded to the south by the Unilever Foods and Aggregate Industries

facilities; to the north by Jarrah Cottages and London Road; to the west by

operational land within the Terminal; and to the east by an area of scrub land within

Purfleet Farm.

1.3. The Proposed Development

1.3.1. An overview of the key aspects of the Proposed Development is as follows:

A new four arm roundabout and associated highways works connecting to

Stonehouse Corner and London Road to provide a new primary access to the

Purfleet Thames Terminal and neighbouring businesses;

New secure entrance and exit facilities to the Purfleet Thames Terminal

(including security gates);

Demolition of any existing structures; and

Associated roads, drainage and landscaping works.

2.0 EIA Assessment Methodology

2.1.1. The Town and Country Planning (Environmental Impact Assessment) Regulations

2011 (as amended 2015) (‘EIA Regulations’) identify two types of development

projects: Schedule 1, for which the requirement to prepare an EIA is mandatory, and

Schedule 2, for which an EIA may be required depending on the size, nature and

location of the development and whether it is likely to have any significant effects

on the environment.

2.1.2. The Proposed Development is considered to fall within Schedule 2 of the EIA

Regulations. Paragraph 10 (f) of Schedule 2 deals with ‘Construction of roads’ and

states that an EIA may be required if the area of the development exceeds 1 hectare

(ha).

2.1.3. The Applicant considers that the Proposed Development is a project for which an

EIA is required. It was agreed that an EIA Screening Opinion would not be sought

and that a Voluntary ES would be submitted as part of the planning application

suite of documents.

2.1.4. The ES outlines the assessment of the likely environmental effects of the Proposed

Development against a range of environmental receptors located within the Site and

surrounding area.

2.1.5. The following topics have been included in the EIA:

Traffic and Transport;

Air Quality;

Noise and Vibration;

Water Resources; and

Ground Conditions.

2.1.6. In addition to the environmental assessments listed above, landscape, visual and

terrestrial ecology have also been considered.

Purfleet

2.1.7. The existing Terminal has an extensive planning history. Many of the consents are

for individual buildings, but others cover a much larger geographic area within the

Terminal (mainly associated with parking and storage).

2.1.8. Most of the planning applications have been granted planning consent. Table 2.1

sets out the details of these planning permissions. The extents of the extant planning

applications within the Site are shown on Figure 2.1.

2.1.9. These developments are subject to planning approvals and within the control of the

Applicant. Consequently, these four permissions along with the ports current

operational infrastructure comprise the future baseline against which the impacts of

the Proposed Development have been assessed.

2.1.10. With regards to the Transport, Air Quality, Noise and Vibration assessments, a

quantitative assessment has been undertaken, whereby a model has been run to take

account of committed developments within 1km of the Site (as agreed with TC).

This approach has been taken to ensure that the assessment models take account of

future traffic growth within close proximity of the Site. The committed

developments along with those in Table 2.1 form the future baseline for the

transport, air quality and noise assessments.

2.1.11. The assessment process for each environmental topic was undertaken in line with

topic specific legislation, planning policy, and guidance documents as outlined in

each chapter of the ES. The significance of likely environmental effects and any

proposed mitigation has been identified.

2.1.12. Consultation has been undertaken with a range of prescribed and non-prescribed

consultees. Each chapter in the ES refers to the specific consultation undertaken.

2.1.13. A cumulative assessment has been undertaken as required by the EIA Regulations.

The cumulative assessment considers the cumulative effect of the Proposed

Development being carried out alongside any other reasonably foreseeable

developments in the locality. The list of cumulative developments has been agreed

with TC and are set out in Table 2.1.

2.1.14. In addition, each of the environmental assessments interact to some degree, and the

ES includes a description of the ‘inter-relationship’ between various factors, setting

out how the particular topic area has been influenced, or has been informed by,

other environmental assessments.

3.0 Alternative Sites and Design Iterations

3.1. Introduction

3.1.1. This chapter describes the alternative sites that have been considered during the

design and assessment process.

3.2. Alternative Sites

3.2.1. Alternative sites have not been considered for the roundabout as its function is to

create a new access to the operational areas of the Terminal.

3.3. Design Evolution

3.3.1. An alternative design arrangement was considered during the preliminary stages of

the Proposed Development which looked at the potential to create a fifth arm to the

Stonehouse Corner roundabout. The reasons for discounting this option were:

A fifth arm could not be accommodated on the existing roundabout due to the

proximity of the new and existing London Road arms, therefore the roundabout

would need to be enlarged;

The constraints imposed by the current land use and existing highway

alignment meant that an enlarged roundabout could only be accommodated by

elongating the roundabout to the south;

Stonehouse Corner roundabout is on a steep grade, 6% measured across the

central island between inside channel lines. The enlarged roundabout would

match this grade, creating a hazard for vehicles picking up speed along the

extended eastern downhill arm, and turning sharply to the right in order to

remain on the roundabout;

There is a significant level drop beyond the current southern arm of Stonehouse

roundabout, approximately 3.5m over 40m which would need to be filled in

order for the roundabout to be enlarged;

Diversion/protection work to the existing gas main would be required; and

Purfleet

10

Build ability and traffic management issues would be difficult to enlarge the

roundabout whilst keeping existing routes open.

3.3.2. The proposed ‘dumbbell’ solution creating a new roundabout was considered to be a

better solution and involved a number of key benefits including:

Being a largely offline solution located on the Applicants land, therefore

avoiding unnecessary delays to road users that would otherwise have been

necessary for the enlargement of the Stonehouse Corner Roundabout; and

Pedestrian desire lines to and from Purfleet are maintained, and there is no net

increase to the overall length of the pedestrian routes.

Purfleet

11

4.0 Project Description

4.1.1. The overall vision for the Terminal is simply to improve safety and increase

efficiency. A review of the existing access and internal circulation routes of the

existing Terminal has been key to making this possible.

4.1.2. The vision will be achieved by applying two basic principles:

1) Improving the site access and internal circulation routes which will reduce HGV

traffic on London Road; and

2) Reducing the reliance upon the level crossings within the Terminal.

4.1.3. The individual elements of the project are described in detail below.

4.2. A new primary Site access in the form of a new roundabout at the

London Road/Jurgens Road Junction

4.2.1. A new primary site access will be constructed in the form of a new roundabout at

the London/Jurgens Road Junction. The new roundabout will have four arms and

will replace the existing London Road/Jurgens Road Junction.

4.2.2. The new roundabout arrangement will remove all HGV traffic associated with the

internal operation of the Terminal from London Road, with the exception of the car

transporters accessing the former Paper Mills Site (as per the consented planning

application - 15/00268/FUL).

4.3. Security Gate Complex

4.3.1. A Security Gate Complex (SGC) will be constructed to the rear of Jarrah Cottages.

Access to the SGC will be gained from the western arm of the new roundabout and it

will process all of the HGV traffic entering and exiting the Terminal (with the

exception of the Paper Mills Land, as explained above).

4.3.2. All vehicles will be required to pass a porter lodge on entry and exit. The porter

lodges will check freight in and out of the Terminal and inform drivers on where

their cargo should be located. The porter lodges will be located on a central island

(2.8m wide) between the lanes.

Purfleet

12

4.4. Landscape Treatments

4.4.1. The landscape strategy for the Site seeks to enhance the existing landscape areas

which are located along the edges of the proposed London Road roundabout. The

proposed strategy will seek to retain as much of the existing vegetation as possible.

Key areas for retention of vegetation are along the Site’s boundary with London

Road and the existing tree lined earth bund to the rear of Jarrah Cottages to ensure

that adequate tree cover is retained through a scheme of appropriate planting and

maintenance.

4.4.2. New areas of soft landscaping including trees, shrubs and areas of grass will be

created between the arms of the roundabout.

4.5. Lighting Strategy

4.5.1. All lighting comprises of LED luminaires for longevity and efficiency. Lighting has

been designed based on 16m high columns within the security gate complex, 10m

high columns for the carriageway lighting in order to match the height of the

existing columns, and 5m high columns for the pedestrian-only route to the north of

the proposed roundabout.

4.6. Signage

4.6.1. All traffic signs and road markings have been designed in accordance with the

Traffic Signs Manual and the Traffic Signs Regulations and General Directions

(TSRGD) 2016, supplemented where appropriate by Local Transport Note 1/94.

Regulatory and warning signs, and road markings advise of speed limits, weight

restrictions, pedestrian crossing points, the combined foot and cycleway and the

proposed London Road roundabout. Further detail is contained in the Design and

Access Statement.

4.7. Surface Water Drainage Strategy

4.7.1. New drainage system comprising a network of drains, and surface water collection

systems consisting of channels, gullies and kerb drains that connect directly into the

Purfleet

13

carrier drains. Surface water attenuation, where required, shall utilise oversized

pipes for storage.

4.8. Ecological Mitigation

4.8.1. An area of Open Mosaic Habitat will be created on the length of former London Road

which is no longer in use.

4.8.2. The embankments on the southern edge of the new London Road roundabout will

be planted with trees and shrubs and managed for ecological enhancement.

4.9. Construction Programme and Phasing

4.9.1. Subject to planning approvals, the construction of the Proposed Development will

be phased over 8 months and is anticipated to commence by the end of 2017 with an

anticipated completion date in 2018.

4.9.2. A Site Management Plan will be implemented to ensure health and safety,

environmental protection and quality are carefully managed and monitored during

the construction phase.

4.9.3. A Construction Traffic Management Plan shall be implemented during the

construction phase to minimise the effects of construction traffic upon local

receptors during the construction phase.

Purfleet

14

5.0 Traffic and Transport

5.1.1. The transport assessment considers the construction and operational effects of the

Proposed Development on the local transport network which comprises of the

highway network, pedestrian movement, cycling and public transport.

5.1.2. Consented developments have been included within the future baseline traffic

scenario which forms the basis of the transport assessment.

5.1.3. The IEMA Guidelines for the Environmental Assessment of Road Traffic (1993)

suggest a range of factors to be considered when determining the level of the

environmental impacts of development. The factors considered within the

Transport Chapter include: severance, driver and pedestrian delay, pedestrian

amenity, fear and intimidation and accidents and safety.

5.1.4. Although the construction works will generate a temporary increase in traffic

movements on the highway network in the vicinity of the Site, it is judged that the

Proposed Development would have a negligible effect on receptors during

construction with regard to all of the above factors.

5.1.5. The Proposed Development will not in itself generate any additional traffic and the

provision of a new access at the roundabout will result in redistributed traffic flows.

It is judged that all effects of the Proposed Development on receptors will be

negligible, and there will be no Significant effects on traffic or transport.

5.1.6. Although the effects are judged to be negligible, mitigation measures have been

suggested. These include the production of a Construction Logistics Plan which

would include details of haul roads and how pedestrian and cyclist safety would be

prioritised during construction.

5.1.7. Overall, there will be no Significant effects on traffic or transport as a result of the

Proposed Development.

Purfleet

15

6.0 Air Quality

6.1.1. An air quality assessment has been carried out to assess both construction and

operational effects of the Proposed Development.

6.1.2. An assessment of the potential effects during the construction phase concluded that

releases of dust and particulate matter is likely to occur during construction

activities. However, through good site practice and the implementation of suitable

mitigation measures, the impacts will be effectively mitigated.

6.1.3. It is also anticipated that there will be a temporary increase in vehicle movement

during the construction phase, but this would not result in any Significant impacts.

6.1.4. There is not anticipated to be any increase in vehicle movements associated with the

operational phase of the roundabout.

6.1.5. There would be a potential benefit in air quality to locally sensitive receptors along

London Road as a result of the Proposed Development. The proposed roundabout

would remove the majority of heavy duty vehicles from London Road by redirecting

them into the Site. The impact of operational phase road traffic emissions is

therefore considered to be not Significant and beneficial.

Purfleet

16

7.0 Noise and Vibration

7.1.1. The noise and vibration assessment considers the likely effects of the Proposed

Development with respect to noise and vibration. These include the effects of

existing noise and vibration conditions at the Site and the effects of noise and

vibration generated by the Proposed Development on surrounding properties,

during both construction and operational phases.

7.1.2. The assessment has been based on a series of environmental noise measurements

undertaken at the Site which have been used to generate noise predictions.

7.1.3. The impact of noise and vibration during construction of the Proposed Development

has been predicted and assessed in accordance with BS 5228. Mitigation measures

are recommended which, when implemented, are capable of ensuring that the

impact of noise and vibration during the construction of the Proposed Development

is adequately controlled. These measures will be implemented through a

construction environmental plan.

7.1.4. For the operational phase, an assessment has been carried out in accordance with

the adopted criteria (BS:4142:2014) to determine the level of impact on sensitive

receptors in the vicinity of the Site.

7.1.5. The assessment determined that an acoustic fence barrier is also considered

appropriate to protect the private amenity spaces of Jarrah Cottages from the noise

egress associated with the security gate complex. The acoustic fence shall replace the

existing fence which is located on the landscaped bund to the north of the security

gate complex. There will be no impact with respect to vibration associated with

operational phase activities.

Purfleet

17

8.0 Water resources

8.1.1. This chapter of the ES assesses the potential effects on flood risk impacts and water

resources receptors, including: groundwater quality and quantity; surface water

quality, hydrology and geomorphology (rivers, ditches, lakes, ponds and estuarine

waters); and, Water Framework Directive (WFD) compliance, which is considered at

the water body scale.

8.1.2. To assess the impacts of the Proposed Development on these receptors a set of

threshold criteria have been defined to establish the sensitivity, magnitude and

significance of the impacts identified. Baseline information for the local area was

gathered from Thurrock’s Strategic Flood Risk Assessments (FRA) and from relevant

assessments included in previous planning applications within the vicinity of the

Site.

8.1.3. The Site is located predominantly within Flood Zone 3, which is at ‘high’ risk of tidal

flooding from the Thames Estuary. A few small areas of high ground are within

Flood Zone 2, which is at ‘medium’ risk of flooding. However, the whole Site is

protected by tidal flood defences managed by the Environment Agency.

8.1.4. The Proposed Development could have a potential effect on flood risk and water

resources. Whilst some potential impacts on the water environment have been

identified as a result of the Proposed Development, it is considered that following

improvements to the Site drainage system (which will provide sufficient capacity

over the lifetime of the Proposed Development), that the Proposed Development

would not increase the risk of flooding to on- or off-site receptors, and in the long

term effects would be beneficial.

8.1.5. The risks identified to water quality can be managed through a combination of

tertiary mitigation such as good practice during construction; and mitigation which

would comprise of ground investigation and risk assessment, followed up with

appropriate measures (such as ground remediation) as necessary.

Purfleet

18

8.1.6. Following the implementation of all suggested mitigation measures, it is judged that

there are no Significant effects on water quality. The Proposed Development is

therefore judged to be compliant with the Water Framework Directive.

Purfleet

19

9.0 Ground Conditions

9.1.1. The ground conditions assessment presents the approach and findings of the

assessment of potential effects of the Proposed Development on human health, soil,

groundwater and surface water with respect to the ground conditions at, and in the

vicinity of, the Site.

9.1.2. To assess the impacts of the Proposed Development a set of threshold criteria have

been defined to establish the sensitivity, magnitude and significance of the impacts

identified.

9.1.3. Due to its industrial use the Site has a long history of potentially contaminative

land-use, and ground investigations have demonstrated the presence of ground

contamination within the vicinity of the Site.

9.1.4. A number of potentially Significant effects have been identified relating to exposure

to ground gas and contamination of construction workers, site operatives and local

residents, and pollution of the deep aquifer and identified groundwater abstractions

due to contamination leaching or migration.

9.1.5. However, suitable mitigation measures have been proposed which include the use

of PPE and good practice during construction, further ground investigations and risk

assessments followed up with any appropriate measures as necessary.

9.1.6. Implementation of these mitigation measures would result in no Significant

residual effects of the Proposed Development on ground conditions and

contamination.

Purfleet

20

10.0 Other Environmental Considerations

10.1. Landscape and Visual

10.1.1. A full landscape and visual impact assessment has not been undertaken as it is

judged that due to the nature of the Proposed Development, the industrial character

of the receiving environment, and limited nature of visual receptors likely to be

affected, that Significant landscape and visual effects are unlikely to arise.

10.1.2. In relation to landscape character, the Site lies within landscape character area

(LCA) E3 – West Thurrock and Purfleet Urban Area which extends from Purfleet

town centre to West Thurrock. The Thurrock Landscape Capacity Study (March

2005) notes that the area is dominated by a range of large commercial buildings and

warehouses. Overall, the Site and its immediate surrounds has an industrial

character, although there are areas of residential development to the north and west

of the Site along London Road.

10.1.3. Site work has confirmed that the Site is well screened and all potential landscape

and visual receptors are contained to a short section of London Road between

Vellcaott Close and Stonehouse Corner roundabout. Where views of the Site are

available, they are currently characterised by existing port activity which includes

the movement of vehicles (cars and HGV lorries), cranes, ships, and associated

infrastructure such as lighting columns, surface level car parks and container stacks.

10.1.4. Landscape mitigation has been embedded into the design and includes the retention

of existing trees and vegetation where possible. Further native and ornamental tree

and shrub planting has been also proposed around the roundabout to filter views of

the surrounding industrial context and provide an attractive entrance to the

Terminal.

10.1.5. Effects on landscape character resulting from the Proposed Development would

generally be confined to the Site itself, and would result in the loss of a small section

of scrub along Jurgens Road. However, overall, there will be a net gain in tree and

shrub planting on the Site and the effect on landscape character would be negligible.

Purfleet

21

10.1.6. In relation to visual receptors, effects are likewise very constrained and localised

with potential receptors including residents and users of London Road (including

Jarrah Cottages), Vellacott Close and High House Production Park. It is judged that

there will be no Significant effects on these receptors from the Proposed

Development.

10.2. Ecology

10.2.1. The majority of the Site comprises of areas of hardstanding related to port activities

including surface level storage for cars and shipping containers. These areas do not

support vegetation and are assessed to be of negligible ecological value. There are no

statutory or non-statutory designated wildlife or nature sites within or adjacent to

the Site.

10.2.2. The Site also includes a 0.93ha section of Purfleet Farm which is an area of vegetated

land to the south of London Road and east of Jurgens Road. This section of Purfleet

Farm comprises of patchy scrub and a vegetated ditch along the western boundary, a

small area of scrub to the northern boundary, an area of species-poor neutral

grassland in the north-west corner and a small area of sparsely vegetated hard-

standing/grassland below the Channel Tunnel Rail Link.

10.2.3. It is judged that Purfleet Farm, when considered as a whole, meets the definition for

open mosaic habitat (OMH) on previously developed land, which is a habitat of

principal importance for the purposes of conserving biodiversity. One of the main

reasons for the habitat being a priority is its importance for invertebrates.

10.2.4. An extended Phase 1 habitat survey was carried out in June 2016 and desk based

studies were also undertaken to assess the effects of the Proposed Development on

habitats and species within and adjacent to the Site.

10.2.5. The principle ecological impact of the Proposed Development on habitats would be

the loss of a small area of scrub and tall herbaceous vegetation along the boundary of

Purfleet Farm which is of low ecological value. There would be no additional

ecological impact over and above the future baseline situation on species-poor

neutral grassland.

Purfleet

22

10.2.6. There will be a minor reduction in the OMH within Purfleet Farm (approximately

10%), and the principle of loss of OMH within the northern half of Purfleet Farm has

been previous agreed in a consented planning consent (Ref: 07/01217TTGOUT and

11/50431/TTGETL).

10.2.7. To mitigate against the small loss of OMH arising from the Proposed Development

the southern section of Purfleet Farm will be managed to enhance biodiversity, and

additional landscaping for the new roundabout will incorporate proposed areas of

vegetation.

10.2.8. This vegetation will include two areas of successional vegetation/open flower rich

grassland to incorporate suitable habitats for invertebrates and compensate for the

loss of OHM. Native tree and scrub planting along the south-east Site boundary will

also provide a replacement for tree/scrub loss along the Purfleet Farm boundary.

These measures will adequately address the minor habitat loss associated with the

Proposed Development.

10.2.9. A small proportion of the area of habitat suitable for nesting birds and reptiles

within Purfleet Farm will be affected by the Proposed Development (approximately

10%). Precautionary mitigation will involve removing vegetation outside of the bird

nesting season, and the removal of ground vegetation by hand under an ecological

watching brief to encourage any reptiles present to move away from the working

area before any machinery is used.

10.2.10. Provided that the mitigation is carried out as suggested, it is judged that there will be

no Significant effects on reptiles or birds as a result of the Proposed Development.

11.0 Cumulative Assessment

11.1.1. In accordance with the EIA Regulations, the EIA needs to consider the cumulative

effects of the Proposed Development in combination with the environmental effects

of other developments on sensitive receptors identified through the EIA process.

11.1.2. Sensitive receptors have been identified in individual chapters of the ES and these

have varying degrees of sensitivity to change as a result of the Proposed

Development. Regard has been given to the sensitivity of the identified receptors to

ensure that consideration is then given to those which are particularly sensitive to

impact. The professional judgement of those undertaking the ES as well as topic

specific criteria, legislation or guidelines have been used to identify the degree of

sensitivity

11.1.3. Following the identification of projects within a 1km radius of the Site which have a

reasonable prospect of coming forward before or at the same time as the Proposed

Development, a list of seven cumulative sites was agreed with TC.

11.1.4. Each of these developments were reviewed for potential environmental effects on

respective environmental topics, and were subsequently assessed for potential

cumulative effects resulting from the developments in conjunction with the

Proposed Development. The combined cumulative effects of each of the

developments in combination with the Proposed Development were then assessed

for each of the environmental topics, and no significant cumulative effects have

been identified.
