10

MARINE LICENCE APPLICATION

• Full compliance with all legislation
• Engaged world-class consultancy firm:
• Environmental Impact Assessment study
• Environmental Statement – over 1,500

pages

11

OPTIONS

• Dredged material -
• Goodwin Sands
• Elsewhere
• Land based aggregate
• Material from navigational dredging
• Recycled aggregate

12

OPTION SELECTION

• Goodwin Sands - least overall

environmental impact

• Habitat recovers naturally - no lasting

effect on the eco-system

• Avoids long-haul shipping or 300,000

lorry movements

• PLUS local material recycled & used –

reducing volume required

TECHNICAL WORKING GROUPS 2015/2016

• Coastal Processes
• Ecology
• Archaeology

22

COASTAL PROCESSES

• Wave heights: no change within 4.5km
• f the coast
• Tidal current velocities: no change

within 5km of the coast

• No indirect impacts on coastal erosion

and flood defence along coast

23

ECOLOGY

• Benthic and Fish
• Marine mammals
• With mitigation measures - all residual

impacts negligible or minor

• Proposed scheme should not have any

significant adverse environmental impacts

24

ARCHAEOLOGY

• No direct impacts on known wreck

sites

• Minor impacts on unknown wreck sites
• but offset by mitigations, monitoring

and reporting protocols

• No impact on heritage assets along the

coast

25

26

CONCLUSION

• Thorough environmental studies
• Small proportion to be taken
• No coastal impacts
• Option with least overall

environmental impact

ASSESSMENT CONCLUSIONS

• Wave heights and directions: negligible change
• ffshore and no change within 4.5km of the coast
• Tidal current velocities: negligible change offshore

and no change within 5km of the coast

• Increase in suspended sediment: negligible

change offshore and no change at the coast

• Sediment transport: negligible offshore and no

change at the coast

• No impacts on coastal erosion and flood defence

along coast

ECOLOGY

FROM DR ELIZABETH JOLLEY & DR JENNIFER LEARMONTH ROYAL HASKONINGDHV

37

DESIGNATED SITES & MARINE ECOLOGY

38

DESIGNATED SITES

39

DESIGNATED SITES

• Approach to Designated Sites:
• Zone of Influence (ZOI)
• Dredger transit route
• MMO Scoping Instruction:
• No Habitats Regulations Assessment
• No formal MCZ assessment for Goodwin

Sands rMCZ

• Potential impacts considered:
• rMCZ features
• Habitats and Species of Principal Importance

MARINE ECOLOGY BASELINE SURVEY

41

PROTECTED HABITATS / SPECIES

42

BENTHIC ECOLOGY CONCLUSIONS

• Species / habitat sensitivity = low /

negligible sensitivity

• Direct loss of species = minor impact
• Increase in suspended sediment = minor

impact

• Suspended sediment/ smothering =

negligible impact

• Impact of hydrodynamic changes =

negligible significance

43

SUITABLE SANDEEL HABITAT

44

HERRING SPAWNING GROUNDS

45

FISH ECOLOGY CONCLUSIONS

• Direct loss / damage to fish / eggs/larvae

within dredge area = minor impact

• Direct loss / disturbance to spawning,

nursery / feeding / overwintering grounds = minor impact

• Smothering of fish / fish eggs from

suspended sediments = negligible impact

46

MARINE MAMMALS

47

SEAL HAUL-OUT SITES

48

SEAL HAUL-OUT SITES

In proximity to the proposed dredge area only a very small area is exposed for a short period of time

49

ASSESSMENT CONCLUSIONS

• Underwater noise during dredging = minor

impact

• Collision risk with dredgers= negligible impact
• Disturbance to seals at haul-out sites = minor

impact

• Change or loss of seal haul-out sites =

negligible impact

• Increased suspended sediment during

dredging = negligible impact

• Reduced prey availability = minor impact

50

ASSESSING ANY DISTURBANCE TO SEALS AT HAUL-OUT SITES

• Significant disturbance of seals at haul-out sites is

unlikely due to the dredging

• Precautionary mitigation measures are proposed:
• 500m minimum distance between the dredger and

seals haul-outs

• 1km minimum distance for:
• Harbour seal breeding season (June to July)
• Harbour seal moult period (August)
• Trained marine mammal observer on board

51

ECOLOGY SUMMARY

• With mitigation measures - all residual

impacts negligible or minor

• Proposed scheme should not have any

significant adverse environmental impacts

• Pre-dredge and post-dredge geophysical survey to

include the Admiral Gardner

• On board archaeological monitoring during dredging
• Archaeological monitoring during discharge of dredged

material

• Protocol for reporting discoveries of archaeological

interest

• Written Scheme of Investigation
