 Wheel washing facility; and  Workshops.


5.6.10.2 Pre-Construction Activities 443. Prior to the commencement of the converter station works, a number of pre- construction surveys and studies would be undertaken to inform the design teams when developing the final design including:


 Ecological pre-construction surveys;  Geotechnical investigations; and  Drainage study.


5.6.10.3 Temporary Fencing 444. Temporary fences would be erected along the boundaries of the converter station site for the duration of the construction period.


5.6.10.4 Grading and Earthworks 445. The enabling works that are typically required to facilitate the construction of a converter station facility can vary greatly. The main factors to consider are the overall topography of the site and the previous use of the land in question.


446. The site for the proposed converter station for East Anglia THREE is greenfield agricultural land.


447. The entire area would be stripped of all organic matter and loose rocks. Any waste material encountered would be removed as required by the environmental and geotechnical investigations. Once the surface had been cleared, the grading operations would begin.


448. Materials would be retained on site for use as engineering fill or landscaping depending on the material properties.


449. If it were to prove impossible or impractical to balance the earthwork quantities, it would be necessary to either export excess soil or import new fill soil. Any soil exported would be disposed of at a licensed disposal site. Excavations of foundations and trenches would commence following the completion of grading.


5.6.10.5 Surface Water Drainage 450. At the converter station, the proposed surface water drainage scheme will be designed to meet the requirements of the National Planning Policy Framework (NPPF) by limiting the post development off site run-off to the existing greenfield
