Activities requiring a licence Section 2: Prohibition on unlicensed activities
19.This section prohibits specified activities from being carried out, except in accordance with a licence granted under section 4.
20.Subsection (3) specifies the activities for which such a licence is required. These include the use of a “controlled place” (as defined in subsection (4)) for gas storage or unloading; the recovery of the gas stored; the conversion of natural features (such as salt domes) for use as storage space; and related exploration activities. Such activities also include the establishment and subsequent maintenance of installations (which by section 16 may be fixed or floating structures) for those purposes. However, by subsection (2), a licence will not be required for any activity falling within section 3.
21.Subsection (4) defines “gas” and “controlled place” for those purposes. By contrast to the definition in Chapter 1, “gas” is limited to combustible substances, and must consist wholly or mainly of the substances listed or other substances which may be specified by order. An order specifying a substance for these purposes is subject to negative resolution procedure (see section 94). A “controlled place” is any place within the limits of the territorial sea adjacent to the United Kingdom, (the territorial sea extends 12 nautical miles from baselines established under the Territorial Sea Act 1987 (c. 49)), or within a Gas Importation and Storage Zone designated under section
