Limits of deviation6

In carrying out the authorised development the undertaker may—

a

deviate laterally from the lines or situations of the authorised development shown on the works plans to the extent of the limits of deviation shown on those plans; and

b

deviate vertically from the levels of the authorised development shown on the engineering drawings and sections—

i

in respect of the construction of any noise barrier, to a maximum of 1 metre upwards or downwards; and

ii

in respect of any other work comprised in the authorised development, to a maximum of 0.5 metres upwards or 0.5 metres 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.
