The undertaker must give to the harbour master not less than 7 days’ prior written notice of its intention to enter upon a tidal area for any purpose relating to the construction or maintenance of the authorised development and must provide such details as the harbour master may reasonably require recording how access to the authorised development is to be gained and what exclusion areas are required for the authorised development.

Where emergency or unanticipated access is required for maintenance, repair or safety operations to the authorised development and the undertaker is unable to give 7 days’ prior written notice to the Tees Port Authority, the undertaker may gain access to the tidal areas on giving such prior notice (if any) to the Authority as is reasonable in the circumstances.

The undertaker must give written notice to the harbour master of the completion of the relevant phase within 14 days of completion of the tidal works carried out as part of phase 1 and phase 2.
