BOC Immingham Dissolved Acetylene Project Environmental Statement
� delivery and use of materials, plant, equipment temporary increase in traffic volumes, leading
to generation and deposition of airborne pollutants leading to changes to sensitive habitats
(e.g. salt marsh) within the receiving environment;
� delivery and use of materials, plant, equipment temporary increase activity, leading to
increase in visual disturbance, particularly of wintering, autumn passage and breeding birds
for which the Humber Estuary is designated; and
� delivery and use of materials, plant, equipment temporary increase in traffic volumes, leading
to increase in vibration and noise resulting in auditory disturbance, particularly of wintering,
autumn passage and breeding birds for which the Humber Estuary is designated; and
� ground preparations and inappropriate use, handling and storage of construction
commissioning materials and wastes, potentially resulting in:
- dust and litter generation (and smothering of sensitive habitats), and
- leaks and spills leading to temporary contamination of habitats.
Operation
10.89 The potential activities and impacts associated with the operation of the Project, which could result
in effects on ecological receptors, are summarised below:
� operation of the plant and movement machinery noise generation resulting in auditory
disturbance to species, particularly wintering, autumn passage and breeding birds for which
the Humber Estuary is designated;
� operation of the plant light generation and movement of people and machinery resulting in
visual disturbance to species particularly wintering, autumn passage and breeding birds for
which the Humber Estuary is designated;
� operation of the plant generation and deposition of airborne pollutants leading to changes to
sensitive habitats (e.g. salt marsh) within the receiving environment;
� increased traffic generation resulting in vehicle emissions with generation and deposition of
airborne pollutants leading to changes to sensitive habitats (e.g. salt marsh) within the
receiving environment; and,
� spillage leakage from inappropriate storage and handling of raw materials, chemicals and
wastes, resulting potential contamination of habitats within the Estuary via Middle Drain and
or groundwater.
Impact Assessment
Construction
10.90 Table 10.6 provides a discussion of potential impacts on the qualifying interest features of the
statutory designated Humber Estuary (incorporating all aspects of the qualifying features for the
SSSI, SAC, SPA and Ramsar site) based on whether the qualifying features are likely to be within
the zone of influence of the proposed development during construction and whether impacts could
result in a significant effect.
10.91 This information has been adapted from the information to support a HRA Stage 1 Screening
Report 6 .
10.92 Table 10.7 discusses potential construction impacts on non-statutory designated sites, notable
habitats and notable species together with the significance of effect on ecological receptors.
