Paragraph 3 Detailed designI1

The authorised development must be designed in detail and carried out so that it is compatible with the preliminary scheme design shown on the general arrangement plans, works plans and the engineering drawings and sections unless otherwise agreed in writing by the Secretary of State following consultation with the relevant planning authority and local highway authority on matters related to their functions and provided that the Secretary of State is satisfied that any amendments to the general arrangement plans, works plans and the engineering drawings and sections showing departures from the preliminary scheme design would not give rise to any materially new or materially different environmental effects in comparison with those reported in the environmental statement.

The Secretary of State must not approve any amended details under sub-paragraph (1) that exceed the maximum vertical limits of deviation shown on the works plans and on the engineering drawings and sections within the Airport safeguarding zone, unless the Secretary of State, following consultation with Birmingham Airport Limited, is satisfied that a deviation in excess of those limits would not adversely affect the safety of aircraft taking off or landing at, or flying in the vicinity of, Birmingham Airport or result in significant operational limitations being imposed on Birmingham Airport.

Where amended details are approved by the Secretary of State under sub-paragraph (1), those details are deemed to be substituted for the corresponding general arrangement plans, works plans or engineering drawings and sections and the undertaker must make those amended details available in electronic form for inspection by members of the public.
