the King’s Sedgemoor Drain between pylons ZGA1 and ZGA3,
during its construction and must thereafter be retained, unless otherwise agreed by the relevant planning authority, after consultation with Natural England.

National Grid must install large spiral bird diverters on the earth wire between pylons LD125 and LD129 at the next available outage. If the first of (a) or (b) is reached prior to or during the construction of the authorised development, the diverters must be installed during the construction of the overhead lines, or if after energisation of the lines, at the first available outage.
