The landfill known as Sandpit in Tuddenham St Martin which is recorded above to have received inert, industrial and commercial waste with no known restrictions, is also recorded by the British Geological Survey (BGS) as a threat to groundwater and surface water. This site is known to be a Special Site and is under the regulation of the Environment Agency. Consultation with the Environment Agency is currently on- going and further information will be provided within the ES.
19.6 Potential Impacts 69.
Reference should be made to Chapter 5 Description of the Development, for full details of the activities proposed during the construction phase. However, in summary, the activities considered likely to impact on soils, geology and ground condition are:
Scenario 1– ducts for the proposed East Anglia THREE and East Anglia FOUR projects would be pre-installed during construction of the East Anglia ONE project
o Construction of onshore cable systems including landfall joint transition bay and cable jointing locations – installation techniques include pulling cables through existing ducts;
o Construction of an onshore converter station, associated infrastructure and landscaping;
o Creation of temporary construction compounds / HDD compounds / laydown areas;
o Temporary upgrade of existing access tracks, construction of new access tracks and haul roads;
o Stockpiling of topsoil and subsoil; o Re-use of excavated soil in jointing pits; o Disposal of excess spoil offsite to a suitably licenced facility; and o Removal and reinstatement of existing drainage systems.
