If the Relevant
Regulator so requires by a notice in writing (which may be given either before
or after the Service Provider submits an Access Arrangement), the Service
Provider must submit separate Access Arrangements (together with Access
Arrangement Information) for different parts of the Covered Pipeline as
specified by the Relevant Regulator, so that the separate Access Arrangements
in total apply to the whole of the Covered Pipeline. The Service Provider may
(if the Relevant Regulator agrees) voluntarily submit separate Access
Arrangements (together with Access Arrangement Information) for different
parts of the Covered Pipeline, so that the separate Access Arrangements in
total apply to the whole of the Covered Pipeline. If separate Access
Arrangements are submitted in accordance with this clause each part of a
Pipeline that is the subject of an Access Arrangement will be treated as a
separate Covered Pipeline for all purposes under the Code.
