Bank-side vegetation would be retained, with trees and shrubs coppiced rather than grubbed-out where practicable. Any habitat removal required along banks would, where practicable, be restricted to the minimum working width of 35m


Any aquatic vegetation removed during the process would be retained on the adjacent banks for 24 hours to allow the aquatic fauna to return to the water


Bank and bed material would be stored separately to aid reinstatement. Topsoil, subsoil and bedrock will be stored separately and replaced in sequence as part of site restoration work. Where possible spoil would be set back 5m from watercourses to minimise potential for silt run off from the working width


Flume bridges would be in place for the duration of the construction period. At crossings a 5m strip of vegetation would be retained to act as a natural buffer. Full restoration of the site, including the dismantling of any temporary bridges and flume pipes will be undertaken when the whole cable has been laid


Appropriate measures will be applied to match the individual circumstances of each watercourse or ditch crossing. The techniques used will aim to provide rapid reinstatement, bank stabilisation and cable protection. In all instances, banks will be re-profiled to match the existing bank. If necessary, additional measures will be taken to ensure that the banks remain stable. The size of the bank and flow rate in the channel will determine the techniques or combination of techniques to be used, and this will be discussed/agreed with the Internal Drainage Board


Where practical refuelling of mobile plant will be carried out a minimum of 30m from any watercourse (and not on slopes leading to watercourses)


Spill control measures will be employed, including drip trays, nozzles and absorbent pads as appropriate. The design of bowsers, hoses etc. will be checked to ensure that they are not vulnerable to rupture or leak, e.g. because of exposed pipe-work


Mobile plant will be returned to the Construction Consolidation Sites each night


Adequate spill kits will be kept in all site vehicles and plant; additional stocks will be issued to watercourse crossing crews and the emergency crew(s) and staff will be trained in their use


All spillages to ground or watercourses will be reported and recorded as part of incident notification procedures to the statutory authorities
