Jetty Non Technical Summary - EDF Hinkley Point

footprint of the jetty development as this area would not be altered during by the Hinkley
Point C works during this phase of the jetty development, or which continue on from
construction. The main aspects that fall into these categories are, in the first instance,
landscape, heritage (setting) and amenity and with regard to the second category air and
noise impacts.
9.3.6 The building work for Hinkley Point C would significantly alter the local landscape and
have wider visual impact. During the operational period for the jetty the visual impact of
the jetty structure would combine with the Hinkley Point C reactor buildings to generate a
greater visual impact than that of the jetty structure alone. While it could be argued that
the visual and landscape impact would be due to the Hinkley Point C construction works,
it would be difficult to separate out the combined elements of the jetty development and
the new buildings such that specific impacts could be attributed to each. The total effect
therefore has to be considered and in this context the cumulative impact would be
greater than that attributable to the jetty development alone. This conclusion also applies
to the setting of heritage interests where the jetty would form a significant component of
the visible built form.
9.3.7 Assessment of noise and air impacts for the jetty development indicates that they would
be of limited significance during operation. Consequently, no greater cumulative impact is
predicted with respect to these aspects during the overlap period with construction of
Hinkley Point C.
9.4 Cumulative Effects with Other Plans and Projects
9.4.1 There are only a few projects in the wider environment that have could interact with the
jetty development and potentially lead to cumulative impacts.
9.4.2 At a regional level, the proposed Bristol Port Deep Sea Container Terminal project at
Avonmouth is spatially so distant that cumulative effects would be confined to those that
could only operate at a regional level. Apart from a negligible potential traffic / transport
interaction between the jetty development / site preparation works and this project, no
such effects have been identified. In proximity to the jetty development the
decommissioning works for Hinkley Point A are of most relevance, while the continued
operation of Hinkley Point B effectively forms part of the baseline against which impacts
have been assessed for the jetty development.
9.4.3 Available information for the Hinkley Point A decommissioning works shows that the
majority of impacts would be confined to the footprint of the Hinkley Point A site and
therefore outwith any spatial interaction with the jetty development. The cumulative
socio-economic effects are considered to be no greater than the effects of jetty
development / site preparation works alone since the contribution of Hinkley Point A is
already included in the baseline.
9.4.4 During operation of the jetty, there are a number of projects which temporally overlap. Of
these, the proposed new nuclear power station at Oldbury is located at such a distance
from Hinkley Point that the potential for any spatial interaction with the effects of the jetty
is either non-existent or negligible. Potential overlap with the Steart Coastal Management
Project would occur, but the lack of any significant spatial interaction and low magnitude
effects associated with the jetty indicate that any cumulative effects would be negligible.
For the transmission line upgrade into Hinkley Point C, there could be some interaction
with regard to landscape and visual sensitivities however, the overall effect is unlikely to
be significant. This is largely due to the fact that the combined landscape impact of the
jetty and the transmission line upgrade would be significantly subsumed by the much
Hinkley Point C Preliminary Works
