(a) deviate laterally from the lines or situations of the authorised development shown on the Works Plans within the limits of deviation relating to a Work shown on those plans and subject to Requirement 42 carry out construction activities for the purpose of the authorised development anywhere within the Order limits; and

(b) deviate vertically from the levels of the authorised development shown on the sections—

(i) to any extent upwards not exceeding 4 metres in respect of the overhead lines;

(ii) to any extent upwards not exceeding 10% of the maximum height shown on the relevant design drawings in respect of the substations, cable sealing end compounds and permanent bridges; and

(iii) to any extent downwards as may be found to be necessary or convenient.

(2) Pylon LD32 must be constructed, 40 metres northwards from the position shown on the Works Plans within the limits of deviation relating to that Work as shown on those plans together with a corresponding increase in height of pylon LD32 to 36.5m and of pylon LD31 to 40 metres comprised in Work No. 1D shown in the sections (Drawing No 13/NG/0271 – 01_13205_84 revision C, Sheet 4)

(3) Pylon LD51 (and adjacent spans LD50 to LD51 to LD52) forming part of the authorised development comprised in Work No. 1E must not deviate laterally westwards from the lines or situations of the authorised development shown on the Works Plans section D, sheets 5 and 6 within the limits of deviation relating to that Work shown on those plans such that the overhead line cannot be constructed closer to Moorland Park than the centre line of Work No. 1E.
