Article 7 Limits of deviation
The authorised development is to be carried out and maintained within the limits of deviation shown and described on the works plans and in carrying out the authorised development the undertaker may—
deviate laterally within the limits of deviation for those works shown on the works plans to the extent the undertaker considers to be necessary or convenient;
to any extent downwards as may be necessary, convenient or expedient;
in respect of any boundary between the areas of two numbered works deviate laterally by up to 20 metres either side of the boundary as shown on the works plans, with the exception of any boundary with Work No. 1A(iv), any boundary with Work No. 2(d) and any boundary with Work No. 4,
except that these maximum 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 by the undertaker with the relevant planning authority, the relevant statutory nature conservation body and the Environment Agency to the extent that it relates to matters relevant to their functions, 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.
Part 2 (procedure for discharge of requirements) of Schedule 2 (requirements) applies to an application to the Secretary of State for certification under paragraph (1) as though it were an approval required by a requirement under that Schedule.
