Presence of Qualifying Feature in Relation to Proposed Development
and Likelihood for Impacts to Occur
approximately 1 km from the Pyewype Mudflats and there will be controls
in place to avoid any accidental contamination reaching the mudflats via
surface or groundwater (see above).
The air quality assessment (Chapter 6) has concluded that:
� the impact arising from construction activities would be negligible; and
� the impact arising as a result of construction traffic would be negligible
(and there are no sensitive receptors within 200 m of the proposed
construction haul routes).
No observable effect is anticipated on habitats within 1 km as a result of air
quality changes relating to construction of the proposed development.
The main sub-tidal sandbanks occur in the Lower Estuary, east of
Grimsby.
The proposed development is approximately 1 km from the Estuary and
there are no pathways through which any impact could affect this habitat
feature.
There are no saline lagoons within the footprint of the proposed
development or in the vicinity of the proposed development.
The closest of these are North Killingholme Haven Pits SSSI on the south
bank of the Humber over 8 km from the proposed development. There are
no pathways between the proposed development site and the lagoons
which could lead to negative impacts on this habitat.
These species, which are predominantly found in pioneer salt marsh, are
primarily found in the outer Humber and often form the lowest and most
seaward zone of a salt marsh, where they are frequently flooded by the
tide. There are two sub-features of this habitat type: Annual Salicornia
(samphire) saltmarsh community and the Suaeda maritima (sea-blite)
saltmarsh community. The annual samphire community is found within the
Humber Flats and Marshes near Pyewipe but largely toward the mouth of
the estuary and along the coast around Cleethorpes, Spurn head and the
North Lincolnshire Coast). The sea blight community is uncommon and is
found within the Humber Flats, at Spurn Head and along the coast
however the total extent is minimal.
