such longer period beginning with that date as the F4OGA has, on the application of the holder, specified in a notice served under this paragraph on the holder during the period mentioned in paragraph (a).

F8it is satisfied that notice of the application under that provision has been served on—

has contravened a term of the authorisation; or

has contravened any provision of a notice which, under F10section 16, 17 or 17F(9) F11of this Act or section 82(11) of the Energy Act 2011, was served on him in his capacity as the owner of the pipeline (or the proposed owner of the proposed pipeline) to which the authorisation relates,
