8.—(1) In constructing Work Nos. 1, 2, 6, 11, 12, 13, 15, 19, 20, 21, 22, 23, 37, 40, 41, 42, 43, 44, 45, 47, 51, 53 and 55 the undertaker may—
(a)deviate laterally from the centrelines shown on the works plans to the extent that the situation of the centreline is varied by up to a maximum of 3 metres either side of the centreline of that work as shown on the works plans provided the works do not extend beyond the Order limits; and
(b)deviate by up to 3 metres from the points of commencement and termination.
(2) In constructing any other work comprised in the authorised development the undertaker must construct any such work within the lateral limits of deviation shown on the works plan for the relevant work except that these maximum limits of lateral deviation and commencement and termination limits of deviation do not apply where it is demonstrated by the undertaker to the Secretary of State’s satisfaction and the Secretary of State, following consultation with the relevant planning authority, certifies accordingly that a deviation in excess of these limits would not give rise to any materially new or materially different environmental effects from those reported in the environmental statement.
(3) In carrying out any work comprised in the authorised development the undertaker may deviate vertically from the levels of the authorised development shown on the engineering drawings and sections, to a maximum of 1 metre upwards or 1 metre downwards, except that these maximum limits of vertical deviation do not apply where it is demonstrated by the undertaker to the Secretary of State’s satisfaction and the Secretary of State, following consultation with the relevant planning authority, certifies accordingly that a deviation in excess of these limits would not give rise to any materially new or materially different environmental effects in comparison with those reported in the environmental statement.
