331. Note that the haul road requirement under this Scenario 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 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).
332. 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 provide an upgrade to the local infrastructure.
333. Use of existing tracks would be subject to consultation with landowners, therefore the red line boundary displayed on the figures for this PEIR show these 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.
334. It is expected that jointing operations would take up to 10 days spread over a four to six working week period, with up to five workers for each jointing pit.
5.6.3.1 Cable drum transport 335. Each section of cable installed between jointing pits would be delivered to the jointing pit on a cable drum, transported to the site by low loader or cable trailer along public highway to nearest access point, then, where necessary, across agricultural land to the jointing pits. The particular low loader dimensions would depend on the cable length on the drum and thus the drum size.
336. Photos of typical drum transport low loaders and cable trailers are provided in Plate 5.3.
337. No abnormal loads to the sites are to be considered to be necessary in the cable pulling process, and therefore no temporary works are required along the public highway for abnormal loads.
