1 INTRODUCTION

1.1 GENERAL

1.1.1 This Strategy details the proposals for the dredging works that will be

required to provide safe vessel access to the AMEP quay. The

recommended disposal area is determined from the material being dredged

and the suitability of existing disposal sites within the Humber Estuary.

2 DESCRIPTION OF THE SITE

2.1 EXISTING BATHYMETRY

2.1.1 The dredge site is located within the intertidal and subtidal zone adjacent to

the south bank of the Humber Estuary at Killingholme Marshes,

approximately 3.5km to the north west of Grimsby town centre and centred

at Ordnance Survey grid reference 517359, 419018.

2.1.2 The site comprises a gently shelving foreshore, with a narrow, near-shore

margin hosting grasses which passes into mudflats. The bathymetric data

for this area is reproduced in Figure A7.1 and shows the estuary bed slopes

away from the shoreline in a south-west north-east direction with the

lowest bed level within the footprint of the dredge area lying at

approximately -6.1m CD. The gradient of the submarine slope varies, but

at it steepest lies at 1 in 22. The landward edge of the site is marked by a

flood defence bund, comprising a concrete pavement and wall. The crest

level lies at approximately +10m CD.

2.2 PUBLISHED GEOLOGY

2.2.1 The British Geological Survey sheet 81, 1:50,000 series, shows that the

surficial deposits on the site comprise two distinct groups of soils. The near

shore materials comprise estuarine deposits composed of silt, clay, thin

peat layers and undifferentiated beds. Inland from the shoreline, the soils

grade into glacial deposits which are predominantly Till, however there are

outcrops of sand and gravel which lie just to the south of the site. The Till is

reported to be between 10m to 21m thick in the area and contain a coarser

gravel size fraction comprising sandstone, mudstone and chalk. Shell

fragments are also reported to be present within the Till.

2.2.2 The solid geology underlying the surficial deposits comprises the Upper

Cretaceous Chalk which is reported to be in excess of 250m thick in this

region. The Chalk strata dip at a very shallow angle, of the order of 2° to

the north east and east, with an undulating top surface. The undulations

are described as shallow depressions which run in a north west to south

east direction. The upper surface is also characterised by a highly fractured

zone extending apparently to a depth of 10m to 20m, and is reported to be

a function of glacial and periglacial processes.




2.3 SITE INVESTIGATION

2.3.1 A ground investigation was undertaken by Soil Engineering Ltd (part of the

Technology Division of VINCI Construction UK Limited) between 15th June

and 15th July 2010. The scope of works was defined by Buro Happold. The

work was concentrated on the offshore section of the site and comprised

the following work:

• 30 No vibrocores

• Bathymetric Survey

• Magnetometer Survey

• Unexploded Ordnance Desk Study

2.3.2 The results of the investigation are reported in the factual ground

investigation report by Soil Engineering, included in Appendix 7.5 of the ES.

2.3.3 At the request of the Marine Management Organisation (MMO), Able UK

arranged for samples of the estuary bed and mudflats (between 0.5 to 3m

depth) within the proposed dredging area to be collected for CEFAS

analysis. Samples were collected via vibrocores in May 2011. Results are

discussed in Section 5 of this report and presented in Appendix 4.

3 DREDGE VOLUMES

3.1 INTRODUCTION

3.1.1 The proposed dredge depths and anticipated arisings are shown in Figure

A7.2. This section details the volumes expected to be dredged from four

defined areas:

• Turning Area; • Approach Channel;

• Berthing Pocket; and

• Reclamation Area

3.2 TURNING AREA

3.2.1 The turning area is located close to the Humber deep water channel and is

to be dredged to a maintained depth of -9.0m CD; with an initial over-

dredge of 300mm. To the south, the existing bathymetry is between -8.8 to

-9.7m CD; over the northern section the ground rises to around -7.0m CD.

3.2.2 A total of 132,000m3 of spoil will be removed from this location.

3.3 APPROACH CHANNEL

3.3.1 This area is to be dredged to a maintained depth of -9.0m CD; with an

initial over-dredge of 300mm. To the south, the existing bathymetry is

between -8.4 to -10.1m CD; over the northern section the ground rises to

around -5.4m CD.

3.3.2 A total of 682,000m3 of spoil will be removed from this location.




3.4 BERTHING POCKET

3.4.1 A 60m wide berthing pocket will be created parallel to the quay front. The

berthing pocket will be dredged to rockhead and a suitable aggregate

deposited to -11.5m CD in order to create a stable footing for use by jack-

up vessels.

3.4.2 At present the existing bathymetry in the south is -5.5m CD; over the

northern section, the ground rises to a maximum -4.1m CD. Rockhead is

estimated to lie between -12m CD and -20m CD.

3.4.3 A total of 827,000m3 of spoil will be removed in total from this location.

3.5 RECLAMATION AREA

3.5.1 The reclamation area is located within the footprint of the quay. It is

anticipated that 250,000m3 of silt material will be dredged from this area to

reduce consolidation settlement of the reclamation area. An additional

44,500m3 will be removed from the anchorage trench which requires

dredging to -6.2m CD. Total dredge quantities for the reclamation area will

be 294,500m3.

4 GEOTECHNICAL CHARACTERISATION OF ARISINGS

4.1 INTRODUCTION

4.1.1 Summary of the surficial geology encountered in the 2010 vibrocore ground

investigation are presented on Figure A7.3 in Appendix 1. Anticipated

dredge material is shown in red text.

4.2 ALLUVIUM AND SOFT CLAYS

4.2.1 With the exception of vibrocores 11, 14, 18, 23 and 28, alluvial clays and

silts were encountered to depths varying between 0.3m (VC 8) and 3.90m

(VC12). The Atterberg limits tests undertaken on this material show it to

range between a low to high plasticity clay with bands of low and high

plasticity silt. The grading curves (Chart 4.1) show the particle size

distribution to vary, and compositionally the material ranges from gravelly

clay to silty clay with the clay fraction ranging from 11% to 35%. The

undrained shear strength of the alluvium is very low. The maximum shear

strength recorded was 20kN/m2; however, there is a significant proportion

of the data which is less than 5kN/m2.

4.2.2 Peat layers were encountered within the alluvial clays at 6 vibrocore

locations (VC 05, 07, 09, 12, 13 & 15). The peat is generally described as

occurring in thin lenses, which range in thickness from <10mm to <30mm.

At one location however, VC13, two thicker, persistent bands of peat are

recorded, each less than 100mm thick.




Chart: 4.1 Particle Size Distribution Curve: Alluvium

4.3 SILTY AND GRAVELLY SANDS

4.3.1 In general terms the grading test results (Chart 4.2) show the granular

soils to vary between silty sand and gravel, gravelly sand to silty fine sand.

The layer thickness of these granular soils varied generally between 0.3m

and 4.25m

Chart 4.2: Particle Size Distribution Curve: Sands & Gravels

4.4 GLACIAL TILL

4.4.1 The glacial till was encountered in the majority of the vibrocore locations

but was not encountered in VC 07, 08, 09 12 & 15. The till comprises

generally soft to firm, firm, and stiff, low to intermediate plasticity clay. The

undrained strength data shows the strength range to lie generally between

30kN/m2 and 110kN/m2.




4.4.2 The Atterberg Limits of the material lie in a tight range with the plasticity

index (PI) varying between 7% and 25%. The grading curves (Chart 4.3)

show the material to be well graded, with a size fraction ranging from fine

to medium gravel to clay. The clay content ranges between 22% and 62%.

4.4.3 The gravel fraction generally comprises sandstone, mudstone and chalk,

however at certain locations, VC 05, 10, 13, 16 and 22 there is a very high

proportion of chalk present.

Chart 4.3: Particle Size Distribution Curve: Glacial Till

4.5 MATERIAL TYPE AND DREDGING PLANT

4.5.1 Preliminary assessment from a suitably qualified and experienced dredging

contractor suggests that the surficial alluvium, soft clay and the sand &

gravel can all be dredged using a trailer suction hopper dredger (TSHD).

The glacial till however will need to be removed using a backhoe dredger.

The dredge methodology is detailed in Appendix 2. For the purposes of the

environmental assessment, the following respective volumes have been

estimated.

Table 4.1: Estimated Quantities of Dredge Material and Proposed

Dredging Methods

MATERIAL TYPE VOLUME (m3) DREDGE METHOD

Alluvium and Soft Clays 750,350 TSHD

Sands and Gravels 230,800 TSHD

Glacial Till 954,350 Backhoe




5 CHEMICAL CHARACTERISATION OF ARISINGS

5.1.1 Testing has been undertaken in accordance with the sampling plan

provided by Marine Management Organisation (MMO). Samples were

analysed by CEFAS and results are presented in Appendix 4.

5.1.2 In a letter received from Allyn Hogg 27th July 2011 ref: DC9172 (Appendix

5), the MMO confirmed, that “the material to be dredged is suitable for

disposal within the Humber Estuary”.

6 DISPOSAL SITES

6.1 GENERAL

6.1.1 In the absence of any other beneficial use, the default option is to dispose

of all material within the estuary and thereby maintain the sediment

supply. A number of disposal sites are open in the estuary for the deposit of

dredge arisings and these are shown in Figure A7.5. Sites are divided

between those that receive erodible deposits, such as the alluvium and

sands and gravels, and those that receive non-erodible deposits such as the

glacial till.

6.2 ERODIBLE MATERIALS

6.2.1 The closest deposit ground from the site is Humber 3A. This mainly

receives material arising from Immingham Dock, its entrance and riverside

berths as well as Humber Sea Terminal. Dredge volumes from Immingham

has ranged from 1,245,246 – 7,346,646 wet tonnes during the period 1985

-2007. The Harbour Master has advised that, based on current

maintenance dredging, this site is close to capacity. It is assumed not to

have capacity for AMEP dredging.

6.2.2 The closest alternative site is the Middle Shoal deposit ground, Humber 1A

(HU080) which is located immediately south of the Sunk Dredged Channel

(SDC) as shown in Figure A7.6, Appendix 1. Coordinates for HU080 are

shown in Table 6.1.

6.2.3 Humber 1A, HU080, receives an average annual volume of 4,740,002 wet

tonnes of maintenance dredging from the SDC. However, the site has

received up to 8,945,818 wet tonnes. The annual volumes are shown




graphically in the Humber Maintenance Dredging Baseline Document (ABP

HES, 2008); the data is reproduced in Chart 6.1.

Chart 6.1: Sunk Dredged Channel Annual Volumes 1985-2007

Source: Figure 33 Humber Maintenance Dredging Baseline Document (August 2008)

6.2.4 It is proposed that all of the material removed by TSHD is deposited at this

site since the character of that material will be similar to that normally

deposited at the site.

6.2.5 The Marine Management Organisation stated in their letter dated 27th July

2011(Appendix 5), that they were “content for the silty erodible material to

be placed at Humber 1A (HU080)” and that there is “sufficient capacity for

the project’s dredged arisings”

6.3 NON-ERODIBLE MATERIALS

6.3.1 The only available sites for non-erodible materials are the ‘windows’ sites to

the north of SDC: HU081, HU082 and HU083 (coordinates given in Table

6.1) as shown in Figure A7.7, Appendix 1. Based, again, upon the 2009

bathymetric survey, there is potential for these three sites to receive up to

3,500,000m3 of material, refer to Figure A7.8. It is therefore proposed and

confirmed acceptable by MMO, that all non-erodible material is deposited

within these areas.

6.4 DREDGING PLANT AND PROGRAMME

6.4.1 The strategy has been developed with Westminster Dredging plc, a suitably

qualified and experienced dredging contractor with an extensive fleet of

specialised vessels. A preliminary Method Statement is reproduced in

Appendix 2.

6.5 MAINTENANCE DREDGING

6.5.1 Maintenance dredge volumes within the Humber Estuary vary considerably

from year to year; the totals from 1985 – 2007 are illustrated below as

abstracted from the Humber Maintenance Dredging Baseline Document.

6.5.2 All of the maintenance dredge material is re-deposited within the estuary.




Chart 6.2: Total Disposal Tonnage in the Humber

Source: Figure 35 Humber Maintenance Dredging Baseline Document (August 2008)

6.6 IMPACTS ON EXISTING AND FUTURE MAINTENANCE DREDGING

REQUIREMENTS

6.6.1 Annex 8.3 of AMEP Environmental Statement presents 3D Mud Modelling

for AMEP. The model assesses the impact of the proposed quay and

associated dredging along with determining the impact on future

maintenance dredging within the Humber Estuary. Results are summarised

in Table 6.1 below.

6.6.2 Annual maintenance dredge is estimated at between 628,000 and

1,328,000m3.

Table 6.2: Annualised changes to deposition and erosion derived

from the 3D mud modelling

Predicted Annual Increase in

Deposition (m3/Year)

Area 3D mud transport model

Humber Sea Terminal -20,000 to -50,000

South Killingholme Oil Jetty —36,000 to -92,000

Immingham Gas Terminal -4,000 to -8,000

Humber International Terminal -38,000 to -96,000

Immingham Bulk Terminal –60,000 to -148,000

AMEP 502,000 to 1,254,000

Inshore of E.ON and Centrica Intakes 188,000 to 468,000

Total Estimated Annual Maintenance Dredge* 440,000 to 860,000

* Total excludes E.ON and Centrica Intakes

6.6.3 The results suggest a potential for detrimental build up of sediments

around the E.ON and Centrica intakes and as such maybe subject to

maintenance dredging. The extent of which will depend upon how the

sediment impacts on the intake infrastructure. A method statement for

maintenance dredging around the intakes is presented in Appendix 3.




7 IN-COMBINATION PROJECTS

7.1 GENERAL

7.1.1 This section briefly reviews other projects that include dredging works that

are either consented or proposed. The dredging strategies for each of these

projects have been abstracted from relevant planning documents and are

summarised in Sections 7.2-7.7.

7.2 QUAY 2005

7.2.1 On 13th October 2000 ABP applied to the Secretary of State for the

Environment, Transport and the Regions for a Harbour Revision Order

(HRO) under section 14 of the Harbours Act 1964 to authorise:

• the reclamation of an area of 7.5 hectares from the River Humber;

• the temporary diversion of the existing riverside footpath (Footpath Number 22) along the river wall on the north bank of the Humber; and

• dredging in the approaches to and adjoining the new quay.

7.2.2 The Environmental Statement records that all of the dredge arisings,

amounting to 200,000m3, will be placed within the quay works as fill.

Accordingly, none will be disposed of within the estuary. It further records

that the project will not give rise to any significant maintenance dredging.

7.2.3 The Environmental Statement is silent on the impacts of the dredging

works on suspended sediment concentrations in the Humber Estuary.

Accordingly it is concluded that the effects were deemed insignificant.

7.3 IMMINGHAM OIL TERMINAL (IOT) APPROACH CHANNEL

DEEPENING

7.3.1 This scheme includes for an estimated 3,905,000 m3 to be dredged mostly

from within the Humber Estuary. A total area of 427ha of seabed is

affected, 312ha of which are located within the boundaries of the Humber

Estuary Marine Site (EMS).

7.3.2 The application was supported by an Environmental Statement prepared by

ABP Mer. The dredging strategy for the works was detailed in

‘Supplementary Note 2: Dredging and Disposal Strategy’, dated July 2009.

That document shows that over 90 per cent of the dredged material will be

removed by TSHD and will be disposed of within erodible deposit sites.

Approximately 375,000m3, of arisings will be non-erodible clays;

220,000m3 will be disposed of within SDC Sites HU081 - HU083.

7.4 GRIMSBY RO-RO

7.4.1 A Harbour Revision Order for the construction of a new Ro-Ro terminal at

Grimsby came into force on 7th April 2011. The ES for the project records

that 210,000 m3 of material will be dredged for the new berths, the turning

area and the approach channel. Of this 165,000 m3 of arisings will be

erodible and disposed of within the Burcom Sands Deposit Ground; the

remaining 45,000m3 of arisings comprise glacial clays that will be deposited

in the SDC window sites.




7.5 HULL RIVERSIDE BULK TERMINAL

7.5.1 ABP has applied for a Harbour Revision Order for a new bulk terminal near

the eastern boundary of the Port of Hull, between Queen Elizabeth Dock

and the Salt End Chemical Works. The application has not been determined

to date. The proposals include the construction of a new jetty and extensive

dredging works on the approach to the new terminal.

7.5.2 The dredging works total 1,100,000m3 of material in-situ, of which

562,000m3 is erodible and will be dispersed to the water column. The

remaining 548,000m3 is non-erodible glacial clay and gravels. The alluvium

is to be deposited at Hull Middle (HU020) and two new sites subject to a

FEPA licence for them. The glacial till and gravel is to be disposed of in the

SDC window sites.

7.6 GREEN PORT HULL

7.6.1 Green Port hull is a proposed development which is an alternative to Quay

2005. ABP intend to submit a series of applications to cover the cover the

works but are relying on the ABP (Hull) HRO 2006 as the principal consent

for the works.

7.7 SUMMARY

7.7.1 Some of the dredge arisings from the projects listed above will be disposed

of within the same areas as those proposed by AMEP. Table 8.1 details the

estimated dredge quantities for each project for those disposal sites that

are common to the AMEP Proposal.

1.2 Project location In this section we describe the proposed work method of the dredging works for the Able Marine Energy Park. A map of the region is given in Figure 1.

Figure 1 - Map of the project location




2 SCOPE OF WORK The project comprise of dredging and reclamation. The work mainly consists of:

Removing soft (alluvium) in proposed reclamation;

Trench excavation;

Rainbowing selected fill;

Dredging of berthing pocket and approach;

Hydraulic fill for reclamation area.

Figure 2 - Preliminary harbour design




3 WORK METHOD Based on the local conditions, soil information, the properties of our dredging equipment and knowledge gained on other dredging projects, Boskalis has developed the following work method.

3.1 General plan The subsequent dredging plan is proposed (draft):

Activity 1 Dredge alluvium from reclamation area

The 1,400m3 trailing suction hopper dredger Sospan Dau (or similar) would dredge this area (if required) prior to the flap anchor trench excavation and filling by rainbowing. The disposal site will be Humber 2 or Humber 3A.

Activity 2 Excavation of flap anchor trench

A large backhoe dredger such as the Nordic Giant will excavate the trench and side cast the sand and gravel or glacial till.

Activity 3 Rainbow of selected fill over the flap anchors

The 8,000m3 trailing suction hopper dredger Barent Zanen (or similar) will dredge suitable material from marine borrow area and discharge on site by rainbowing over the new quay wall.

Activity 4 Hydraulic fill of reclamation area

The Barent Zanen (or similar) and 16,000m3 trailing suction hopper dredger Oranje (or similar) will dredge suitable material from marine borrow area and discharge on site by pumping through a floating pipeline.

Activity 5 Dredge alluvium from berth pocket, turning area and approaches

The Barent Zanen (or similar) will dredge the alluvium and discharge in disposal site Humber 1A, Humber 3 or Humber 3A.

Activity 6 Dredge sands & gravels from berth pocket, turning area and approaches

As Activity 5 above, however if suitable material is available in sufficient quantities it may be possible to discharge by rainbowing or pipeline into the reclamation area.

Activity 7 Dredge glacial till from berth pocket, turning area and approaches

Backhoe dredger Nordic Giant or Wodan (or similar) will dredge and discharge into two or three split hopper barges such as Frigg, Rind, Cork Sand and Long Sand. The split barges will dispose of the dredged material at the Sunk Dredged Channel disposal areas A, B, C or Holme Channel Deep.

In paragraph 3.3 this work sequence is clarified.




3.2 The proposed disposal areas Material derived from the capital dredging will be deposited in the following locations:

Erodible material will be deposited in Humber 1A (HU080).

Non-erodible material deposited in HU081, HU082 and HU083. Possible future maintenance dredge material will be deposited in HU080

Figure 3 - Disposal areas

3.3 Work sequence In the following the dredging activities are clarified: Activity 1: For this activity the unsuitable layers of alluvium will be dredged from the future reclamation area by means of a Trailing Suction Hopper Dredger (TSHD). To start dredging operations, the TSHD will sail to the dredge area. Once in the dredge area, the suction pipe(s) are lowered to the seabed, the dredge pump(s) are started and dredging commences. After dredging, the TSHD sails to the discharge area to discharge the load of dredged material by opening the bottom doors.




Figure 4 - The future reclamation area is shaded red Activity 2: The flap anchor trench will be dredged by a Backhoe Dredger (BHD). To start dredging operations, the BHD is towed to the location where excavation is to take place. The BHD positions its spuds on the seabed. Dredging with a BHD consists of a cycle of operations. The dredged material can either be side cast or disposed into a split hopper barge. For this activity the dredged material will be side cast next to the designed trench. This material will eventually be part of the reclamation area.

Figure 5 - A BHD is excavating the trench




Figure 6 - A BHD is unloading its bucket in a split hopper barge

The Backhoe will move with the assistance of a tug/workboat. The material will be side cast, so there will be no barge movements within the navigation channel. Anticipated duration 1.5 weeks operating approximately 100 hours/week.




Activity 3: A TSHD will sail to a licenced borrow area within the North Sea and dredge suitable material. After dredging, the TSHD sails back to the discharge area. The dredger will take up position and hold there using a GPS controlled dynamic positioning system, hence no other vessels are involved. When the dredger is in position, the dredged material in the hopper will be mixed with water (fluidised) and pumped overboard through a jet nozzle at the bow of the TSHD. This method is called rainbowing, an illustration is given in Figure 7. The load will be discharged by rainbowing over the flap anchors.

Activity 4: For this activity the TSHD Barent Zanen and Oranje will be used (or similar). The dredged material will be dredged out of a marine borrow area, similar to Activity 3. When the dredger is back near the reclamation area a pipeline will connect the TSHD with the shore. The dredger will take up position and hold there using a GPS controlled dynamic positioning system. A multicat will assist with making the connection to the discharge pipe. The dredged sand is pumped from the dredger(s), through the floating and shore pipelines, into the reclamation area .

Figure 8 - The reclamation area is shaded red

Figure 10 - An example of a reclamation area




Activity 5: The alluvium will be dredged from the berth pocket, turning area and approaches by a TSHD (see Figure 11). The same working method will be used as in Activity 1. The dredged material will be discharged at disposal area Humber 1A Middle Shoal

Figure 11 - The berth pocket, turning area and approaches

Activity 6: The sand and gravels will be dredged from berth pocket, turning area and approaches by TSHD (see Activity 5). If the material is suitable for reclamation it may be possible to discharge this material by rainbowing or a pipeline into the reclamation area. This depends on the quantities. Activity 7: The glacial till will be excavated from the berth pocket, turning area and approaches by a BHD (see Activity 5). The same working method as in Activity 2 will be used, except the material to be deposited on Sunk Dredged Channel HU081, HU082, HU083 by split hopper barges (see Figure 6)..

For discharging the dredged material from a THSD, several options are possible. For this project the following options are being proposed:

Dumping the load by opening the bottom doors;

Rainbowing by means of pumping the load over the bow, through a nozzle;

Pumping the load through a floating and/or sinker pipeline to a reclamation area, the sand is spread out, using land based equipment

Figure 13 - TSHD discharging via bottom doors

4.2 Backhoe Dredger A Backhoe Dredger (BHD) is basically a hydraulic excavator installed on a pontoon. Dredging is executed by the excavator which is mounted on a turntable at the front of the pontoon. An impression of a Backhoe Dredger is given below, in Figure 14.




Figure 14 - General layout Backhoe dredger

The main components of a BHD are:

The pontoon;

The hydraulic excavator, consisting of an excavator, boom, stick and bucket;

The spud poles and spud carrier, or tilting spud. By means of the spuds, the position of the pontoon, during dredging, is fixed. The spud carrier or tilting spud enables the pontoon to move forwards and backwards when the front spuds are lifted.

Dear Richard

PROPOSED AMEP AT KILLINGHOLME – ES & HRA CONSULTATION

Thank you for consulting the Marine Management Organisation (the MMO) on the draft Environmental Statement (ES) and Habitats Regulations Assessment (HRA).

In considering this report, we have consulted with the Centre for Environment, Fisheries and Aquaculture Science and the MMOs district Marine Officer for the Humber. Their comments have been incorporated into this letter.

General comments I have provided our response to the draft ES and HRA in Annex 1 to this letter. However I was disappointed to see that the comments I provided in my response to draft chapters on Friday 3 June 2011 had not been addressed in the full draft ES. Some of them have been highlighted in yellow in the latest draft but it is not clear what this means. Where previous comments do not appear to have been addressed at all, I have left them, marked as “previous advice”, in the comments below. As it is not clear where comments have been addressed this has caused duplication in effort and considerably increased the time required to review the document again, in future applications the applicants should clearly state where comments have been addressed to provide clear a audit trail that all issues are resolved. I trust that the comments provided today will be included in the final ES and I would prefer to see the whole ES again in order to be able to state MMOs broad support.

As these sections of the report are draft, I accept there are figure and text errors and omissions. Therefore I have not mentioned these within the below comments.However these are still present throughout the chapters and annexes reviewed and have at times caused difficulties in understanding the assessment. In particular, inconsistencies in the length of the quay wall and the volume of material to be dredged has varied between reports and between chapters in the draft ES.

There does not appear to be an overall cumulative and in-combination assessment. While these are mentioned in each of the various chapters, there is only reference to other ongoing projects / activities, with little quantification of their combined effects (e.g. section 10.9.3: Long term changes in the hydrodynamic and morphodynamic regime in the aquatic ecology chapter). It would be useful to have an overall section

on in-combination and cumulative effects, where each of the other projects could be assessed as a whole against the AMEP development, as currently it appears piecemeal and is difficult to assess whether a proper cumulative and in-combination assessment has been carried out.

Drafting of deemed marine licenceWe would like to work closely with you in order to draft an agreed deemed marine licence. As you are aware you will require a marine licence to be deemed within any Development Consent Order (DCO) to cover all aspects of the project which would ordinarily fall under the Marine and Coastal Access Act 2009 (MCAA). From the information provided in the Preliminary Environmental Impact Report, this may include:

1. The construction of the quay; 2. The reclamation of intertidal and subtidal area;3. The capital and maintenance dredging; 4. The disposal of dredged material; 5. Any other works below mean high water springs, eg works to outfalls work on

dykes; and 6. Certain activities relating to the creation of compensatory habitat (eg the

breach of a seawall or removal of saltmarsh)

We will need to ensure that the marine licence will be fit for our purposes once deemed, for example, we will we need to ensure that sufficient information is captured to fulfil our Ospar reporting responsibilities. As such, would also like to discuss and agree the format and structure of the deemed marine licence with you.

Within the deemed marine licence you need to take into account all direct and indirect effects to the marine environment and navigation. Therefore you need to take into account comments from other consultees (Environment Agency, Natural England, Maritime and Coastguard Agency etc) to ensure these are fully addressed within the deemed marine licence.

As previously requested, we would also wish to have the opportunity to comment on any provisions within the DCO relating to the creation and/or operation of a harbour authority.

If you have any queries regarding any of the comments within this letter please feel free to contact me.

Yours sincerely

Allyn Hogg Marine Consents Case OfficerMarine Environment Team

Please provide details of how the wave model was calibrated. If the model was uncalibrated, please provide reasoning for this in the final ES.

Annex 8.2:

It would appear that, from Figure 4, the drainage channels of the currently terrestrialside of the compensation site are not represented in the model. Please comment on the significance of this.

3.13: Please provide the source of the quoted erosion and deposition thresholds. Please cite some evidence to indicate relevance to this site.

3.14 and 3.15: these verbal descriptions would be more easily followed if they were given alongside graphical representations (e.g. a time-series of erosion/accretion maps; such maps must have be produced to describe these results). Please detail which area is the accreting area, its size, the rates of change and the spatial variability in bed level changes.

5.2: The second to last bullet point “Away from the proposed quay the combined impact of the development on intertidal and sub-tidal areas will be negligible in comparison with natural variation.” This statement is lacking evidence or citation of evidence elsewhere in the ES.

Chapter 9 Water quality and sediment quality

Table 9.8: Cefas have an Action Level 1 for PAHs of 0.1ppm and for THCs of 100ppm.

There is no mention in this chapter of any potential pathways for contaminated sediments disturbed by the construction activities entering the marine environment. This should be provided for review and in the final ES.

9.10: Hull Riverside Container Terminal / Quay 2005 should now be known as Green Port Hull.

I am satisfied that the material to be dredged is suitable for disposal within the Humber Estuary. The analysis carried out at the Cefas laboratory showed that for all samples, Metals and Tins are only very slightly elevated above AL1 and that the PCBs are for the most part below AL1. The PAHs are above AL1, but are mostly lower than the average for the area. One site (Sample 18, Approach channel sample I at the surface) had double the average levels of C1-N, C1-P and C2-N and 2.5 times the average of C3-N. However upon looking at the sample as a whole (metals, tins, PCBs and other PAHs) I have no issues with this sample.

I am content for the silty erodible material to be placed at Humber 1A (HU080). This site has previously taken several million tonnes of material per annum, however in the last few years the usage of this site has decreased. Therefore given this is a dispersive site, there should be sufficient capacity for the project’s dredged arisings. A detailed dredging plan would need to be agreed closer to the time of the works with the MMO

Humber Estuary. The analysis carried out at the Cefas laboratory showed that for all Humber Estuary. The analysis atory showed that for all samples, Metals and Tins are only very slightly elevated above AL1 and that the samples, Metals and Tins are only very slightly elevated above AL1 and that the PCBs are for the most part below AL1. The PAHs are above AL1, but are mostly PCBs are for the most part below AL1. The PAHs are above AL1, but are mostly lower than the average for the area. One site (Sample 18, Approach channel sample lower than the average for the area. One site (Sample 18, Approach channel sample I at the surface) had double the average levels of C1-N, C1-P and C2-N and 2.5 I at the surface) had double the average levels of C1-N, C1-P and C2-N and 2.5 times the average of C3-N.

Dear Richard, RE: Able Marine Energy Park Dredging Strategy I am writing in reply to your email dated 25th October 2011 requesting comments on the Dredging Strategy report in relation to your proposed application to Infrastructure Planning Commission (IPC) for development consent. 5 Chemical characterisations of arisings The chemical analysis provided does not include any metals and tins results, although I note that these analyses were carried out by Cefas and comments were included in previous advice. There are also three sets of data with differing units included for PAHs and PCBs. Only the dry weight PPM results that are comparable to the Cefas Action Levels need to be included. 6 Disposal sites The document states that 981,150 m3 of material will be disposed of to HU080, Humber 1A and goes on to compare this figure to previous tonnages received at the site. However, the table referenced states tonnages to the Sunk Dredge Channel and not specifically to HU080. I am content that silty erodible material is deposited at HU080. The remainder of the material (954,350m3) is glacial in origin and is proposed to be split across three sites; HU081, HU082 and HU083, however this quantity is not compared to the amounts the sites have received in previous years. Looking at the data for disposal sites HU081, HU082 and HU083, only 463,028 tonnes of material has been deposited to HU081 (all in 1995). However these sites have been used for beneficial use under construction licences, which unfortunately means that no returns are required to be provided and therefore there is no record of how much material has previously been disposed of at these sites. Approximately 1.9M m3 of material from all proposals, including the licensed Immingham Oil Terminal (375,000 m3), are proposed to be deposited at these three sites. Looking at the areas of the disposal sites and the bathymetry data included in the dredging protocol, the sites have the capacity to take this quantity of material. Therefore I am content that stiff glacial material can be deposited at sites HU081, HU082 and HU083. If you intend to refer to this document in the deemed marine licences, the document should also provide the full coordinates of all of the dredge and disposal sites to be used. 6.6 Future maintenance dredging requirements. This section does not provide sufficient detail on the future maintenance dredging requirements to be able to inform a draft marine licence. As is consistent with maintenance

dredging licences issued under the Marine and Coastal Access Act 2009, this document and the associated deemed marine licence needs to identify the quantity of material to be dredged by year, the location of the dredging and of the disposal (including coordinates). Maintenance dredging licences are not usually permitted for a period longer than three years. This is so that the activity can be reviewed at regular periods in view of other projects operating within the Humber and to ensure that the activity remains compliant with both the Ospar and London conventions, which includes a requirement for the analysis of samples every three years. Without this additional information on this, and in view of the last draft deemed marine licence that I provided comments on 11 November 2011, I do not consider that we have had sufficient information to be able to support a deemed marine licence for disposal of dredged arisings from maintenance dredging. 7 In-combination projects The document does include future work planned in the area however, as per previous advice Green Port Hull is not a replacement for Hull Riverside Bulk Terminal, this is a different project. Green Port Hull is Quay 2005. Appendix 2 – Preliminary Work Method Statement This includes the proposed used of some disposal sites (Humber 2, Humber 3A and Holme Channel deep) not mentioned in the main document. Disposal can only take place at those sites which have been previously agreed. We previously recommended (date) that a schedule for dredging be included and that the material is disposed of throughout the year rather than all in a single period. The only schedule provided is a daily schedule and there is no indication as to whether the material will be deposited throughout the year. This methods statement needs to be updated to detail how the material will be disposed of throughout the year and amended such that the discrepancies between the disposal sites to be detailed in the Method Statement match those in the Dredging Strategy. The revised Dredging Strategy and Method Statement must be agreed in writing with the MMO prior to the disposal operations commencing. Deemed marine licences As I have requested previously (most recently 11 November 2011), I strongly encourage you to undertake meaningful consultation on the contents of, and conditions to be included in, the deemed marine licences. As drafted they would not be considered fit for purpose from the MMOs perspective. The deemed marine licences for capital and maintenance dredging should either contain much of the information in this document including the names and coordinates of the dredge and disposal sites to be used, the depth that the dredged areas will initially be dredged to and then maintained at, and a methods statement indicating how the dredging will be undertaken, as well as an annual works schedule. If you intend to refer to the Dredging Strategy and/or the Preliminary Work Method Statement we would wish to see the comments raised in this response, and other relevant comments raised in previous consultations (including that on 11 November 2011), addressed and the documents(s) consulted upon and agreed in writing prior to the dredging commencing. I would encourage you to arrange a meeting to discuss appropriate contents and conditions for all of the deemed marine licences, including the capital dredging/disposal licence and maintenance dredge/disposal licence, and that other relevant organisations are consulted

upon it, for example the Environment Agency, Natural England and the local harbour authority. If you have any queries please feel free to contact me. Yours sincerely,

Anna Gerring
