BOC Immingham Dissolved Acetylene Project Environmental Statement: Vol. 2 Main Text
9.61 The EA operates a flood warning service in areas at risk of flooding from rivers or the sea. Using
the latest available technology staff monitor rainfall, river levels and sea conditions 24 hours a day
and use this information to forecast the possibility of flooding. The site is situated within a larger
geographical area from Immingham to Pyewipe where the EA provides a general Flood Watch
early alert to possible flooding as shown in Figure 9.5. The forecasting of storm surges in the
North Sea increases the likelihood that flood warnings will result in the successful warning of
endangered people prior to the onset of flooding. During construction and throughout its
operation, the proposed development site will be listed on the EA flood warning register.
Figure 9.5 Flood Warning Area (EA 2011)
9.62 A flood warning and emergency evacuation plan will be prepared and submitted to the LPA for
approval before construction of the plant is completed. The emergency evacuation plan will
include the following:
� how the flood warning should be provided and disseminated;
� what will be done to protect the critical infrastructure of the development and how easily
damaged items will be relocated;
� the availability of staff and time taken to respond to a flood warning;
� the use of high level refuges for staff within the plant;
� the time needed to evacuate the site;
� provision of safe access to and from the development;
� the ability to maintain key operations during a flood event; and
Proposed Development Site
� expected time taken to re-establish normal operation following a flood event.
9.63 To ensure the effects of flood risk are minimised during construction, the work will be undertaken
when flood events are unlikely and not predicted. Should a storm with flood potential be predicted
then measures will be put in place to reduce the impacts of flooding, e.g. remove machinery from
low-lying areas. With the measures outlined above, the construction impact from tidal flooding is
considered to be reduced to negligible.
