The undertaker must not carry out any part of the authorised development within the vicinity of the Gwash to Glen pipeline as shown on the Gwash to Glen pipeline plan until the Agency has carried out ground penetrating radar survey to identify the precise location of the Gwash to Glen pipeline and provided to the undertaker a plan showing the result of the survey.

If, in consequence of specified works taking place within 3.5 metres of the Gwash to Glen pipeline, access to the pipeline is obstructed, the undertaker must provide such alternative means of access to the Gwash and Glen pipeline as will enable the Agency to maintain or operate the Gwash and Glen pipeline no less effectively than was possible before such obstruction.

In the event of any damage to the Gwash and Glen pipeline the undertaker must notify the Agency as soon as practicable.
