The Great Yarmouth Third River Crossing Development Consent Order 2020

59.—(1) The undertaker must not in the course of constructing any specified work or protective work or otherwise in connection with such works do or permit anything which results in the deposit of any polluting materials on, in or over the river and must take such steps as the harbour master may reasonably require to avoid or make good any breach of its obligations under this paragraph.

(2) Subject to sub-paragraphs (3) and (4), the undertaker must not in the course of constructing any specified work or protective work or otherwise in connection with such works do or permit anything which results in the deposit of any other materials in the river and must take such steps as the harbour master may reasonably require to avoid or make good any breach of its obligations under this sub-paragraph.

(3) For the avoidance of doubt, the structures comprising the authorised development, and any specified work or protective work shall not themselves constitute a material for the purposes of sub-paragraph (2).

(4) Sub-paragraph (2) does not apply to the deposit by the undertaker of materials (other than polluting materials) in the river if such deposit has been authorised in writing by the GYPA.
