BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
9.8 The Humber Flood Risk Management Strategy 57 provides strategic flood risk management options
for the Humber Estuary taking into consideration proposed sea level rise and the EU Habitats
Directive. The Strategy sets out a long term programme of the works needed to manage the flood
defences within the Estuary over the next 100 years. In general, the EA’s approach to flood
defence in the vicinity of Immingham (Flood Area 24 Immingham to West Grimsby) is to improve
the current system where necessary and avoid locating new developments immediately behind
the current flood defences in case the defence line needs to move in future years. The description
of works and proposed option is ‘Hold the line: Sheet pile toe protection to prevent channel
movements undermining bank and affecting its stability to the north of Middle Drain and local crest
raising. Sheet pile toe protection works with local crest raising and outfall refurbishment to the
south of Middle Drain’. The EA will seek to supplement public funds with contributions from major
beneficiaries and from developers, who will be expected to pay the full cost of any new works
needed to protect their development.
9.9 Further details of relevant planning policies at national, regional and local levels are discussed in
Chapter 4 and are summarised in Appendix 4A. The conformity of the Dissolved Acetylene Project
with plans and policies is discussed in Chapter 17.
Consultation
9.10 A considerable amount of consultation has been undertaken with NELC and the EA in relation to
the proposed development and the issues associated with flood risk. Some of the key components
of the consultation process are listed below:
9 th March 2011: Meeting (NELC, EA, BOC and Atkins) to present the Project to the EA and
to discuss potential flood risk and planning issues.
23 rd March 2011: Issue of Scoping Report 3 to NELC.
27 th April 2011: Receipt of Scoping Opinion 4 from NELC (see Appendix 5.A).
23 rd May 2011: Meeting (NELC, BOC and Atkins) to discuss PPS 25 and classification of
the development.
10 th June 2011: Submission of a letter from Atkins to NELC setting out further information in
relation to BOC’s position regarding PPS 25 and the classification of the
development as essential infrastructure (see Appendix 9.D).
16 th June 2011: Submission of a letter from NELC to the EA setting out further information
in relation to BOC’s position regarding PPS 25 and the classification of the
development as essential infrastructure.
9.11 The Scoping Report 3 received the following comments from the EA regarding the FRA, which
have been taken on board in the production of this Chapter:
� ‘The lifetime of the development will need to be confirmed. The flood risk to the development,
including an appropriate allowance for climate change, will then need to be considered over
the lifetime of the development. If the development is required to remain operational during a
flood event the 0.1% annual probability, plus an allowance for climate change flood event,
should be considered for determining the level at which flood sensitive equipment and areas
of safe refuge are set. Also, other parts of the development will need to be shown to be flood
resilient easily recoverable following a flood.
� The proposal should be accompanied by a robust Flood Warning and Evacuation Plan. As
part of this plan we recommend registration with the Environment Agency’s free Floodline
Warnings Direct service.’
