and h in section 1.3.
� The construction of an access road from the existing access road
to GGOWF.
� Cable sealing compounds and gantries to connect to the existing
overhead transmission lines.
� Construction of the onshore cable connection which will be
implemented by horizontal directional drilling from the
foreshore of Sizewell Beach to the location of the proposed
transition bays south of Sizewell Gap road (requiring surface
excavation only at each end), surface excavation from the
transition bays to the substation, with horizontal directional
drilling where it passes under Sizewell Gap road and the minor
road that runs south from Sizewell Gap road. This will mean that
existing roadside hedgerows will be retained. It is not anticipated
that construction of the onshore cable connection will result in
the loss of any existing trees, woodland or hedgerows. There will
be a temporary compound on Sizewell Beach.
The onshore cabling between the transition bays and the
substation will be approximately 900m in length. The aim will
be to utilise one continuous cable over this distance. However it
is possible that two sections will be required and jointed together
at a joint box. Consideration will be given to locate any joint
boxes close to a field boundary to minimise any impact to
agricultural activities.
� Planting and other landscape works to a scheme agreed with the
relevant planning authority. The mitigation strategy is discussed
in section 13.0 and included in Appendix 4.
