18.5.6 Marine Aggregate Dredging 58. No aggregate dredging areas exist within the proposed East Anglia THREE project boundaries (Figure 18.3). The closest dredging area is licence area 430 which is located 924mto the north of the cable corridor and is operated jointly by Cemex and Tarmac Marine Dredging. Historically area 496 (Ben Acre) was dredged however this was surrendered in February 2013.

18.5.7 Ministry of Defence Activities 61. No naval activities are known to be undertaken within the East Anglia Zone. However, practice and exercise (PEXA) areas do exist to the south and south west, with the North Galloper PEXA situated approximately 16km south of the East Anglia THREE offshore cable corridor (Figure 18.4). PEXA sites themselves can refer to any area used for practice by UK armed forces.
18.5.8 Unexploded Ordnance 62.
The area surrounding the proposed East Anglia THREE site was important during both World Wars due to its proximity to the ports of Felixstowe, Harwich, Lowestoft and Great Yarmouth. This means there is high potential for munitions related to wrecks in the vicinity of the East Anglia THREE project containing UXO items.
