respect of both Scenario 1 and Scenario 2). The following paragraphs describe these differences.


61.


The haul road requirement under Scenario 1 is currently being reviewed. In the original design iteration for this option it was assumed that all access to the onshore cable route would be made via those access points identified as accesses for East Anglia ONE. This would in places require the removal of hedgerow and reinstatement of haul road to access isolated locations for jointing pits (i.e. those locations which are far removed from field boundaries adjoining roads).


62.


It is desirable to reduce the requirement for haul road for two reasons. Firstly under Scenario 1 the bulk of the materials delivered to and taken off site will be for the creation of the haul road itself. Any reduction in haul road requirement would reduce overall material volumes and therefore vehicle movements. Secondly, if existing tracks could be upgraded to access remote jointing pit locations this would reduce disruption to arable fields (and hedgerows and other sensitive habitats) and potentially provide an upgrade to the local infrastructure.


63.


Twenty two new accesses which require alteration of the existing onshore cable route boundary have been identified and these are listed in Chapter 5 description of the Development (see section 5.6.5.4, and shown in Figures 5.2 to 5.10).


64.


Use of existing tracks would be subject to consultation with landowners, therefore the onshore cable route boundary displayed on the figures for this PEIR show these existing track areas within the boundary in order to prompt consultation on the possible use of new access routes not previously consulted on for East Anglia ONE.


65.


The final onshore cable route, with the amendments discussed above, is the basis for the assessments within this Preliminary Environmental Information report (PEIR) and is shown in in Figure 1.2. Figure 4.1 shows the onshore cable route in the context of environmental constraints, while Figure 4.2 shows the onshore cable route in the context of statutory environmental designations.


4.4.6 Converter station 66.


The location of the proposed East Anglia THREE onshore converter station is influenced by the agreement with the National Grid for the connection of 3.6GW into the existing substation at Bramford.


67.


The broad area within which the East Anglia THREE converter station would be located was determined during the development of East Anglia ONE. This section explains the process by which this area was chosen.
