Within 24 months of the permanent cessation of the operation of Work No. 4, the undertaker must submit details of a decommissioning scheme for the restoration and aftercare of the land for Work No. 4 (with the exception of the flood defence line wall which will remain in situ) to the MMO for approval in writing in accordance with the procedure in Part 4.

The scheme must include details of structures and buildings to be demolished or retained, details of the means of removal of materials following demolition, phasing of demolition and removal, details of restoration works (including any monitoring) and phasing thereof.

Unless otherwise agreed by the MMO in writing, the mitigation measures in place for habitat loss as a result of the construction of Work No. 4 must be maintained following the decommissioning of Work No. 4 and any routine maintenance and adaptive management measures and monitoring must continue whilst the measures are in place.

Sub-paragraph (3) does not apply where the MMO, in consultation with the relevant statutory nature conservation body, determines based on monitoring data submitted by the undertaker that the intertidal habitat lost as a result of the construction of Work No. 4 has been restored following the decommissioning of Work No. 4 to provide a similar habitat as was present prior to the works being carried out that has the potential to be used by roosting and foraging birds.

Unless otherwise agreed by the MMO in writing the decommissioning scheme must be implemented in accordance with the phasing set out therein as approved by the MMO.
