59.—(1) The Department, after consultation with the Authority, may by order designate any pipe-line as a pipe-line to which Article 60 applies; and references in that Article to a “designated pipe-line” are to a pipe-line which is designated under this Article.
(2) A pipe-line shall not be designated under this Article unless—
(a)it is a high-pressure pipe-line; or
(b)it is connected to a high-pressure pipe-line which is so designated.
(3) For the purposes of this Article a pipe-line is a high-pressure pipe-line if it has a design operating pressure exceeding 7 bar gauge.
(4) Before making an order under this Article, the Department shall give notice—
(a)stating that it proposes to make the order and setting out its effect; and
(b)specifying the time (not being less than 28 days from the date of publication of the notice) within which representations or objections with respect to the proposed order may be made,
and shall consider any representations or objections which are duly made and not withdrawn.
(5) An order under this Article may provide that the order (or so much thereof as designates any particular pipe-line) shall cease to have effect on the happening of any event specified in the order.
(6) If an order under this Article contains provision to the effect that the designation by the order of any particular pipe-line is, subject to any provision made by virtue of paragraph (5), to have effect for a period specified in the order, the Department shall not—
(a)revoke that order; or
(b)amend that order so that the designation of that pipe-line ceases to have effect,
before the end of that period.
60.—(1) The Department after consultation with the Authority, or the Authority with the consent of the Department, may in accordance with this Article modify—
(a)the conditions of a particular licence under sub-paragraph (a) or (c) of Article 8(1) of the Gas Order; or
(b)the standard conditions of licences under sub-paragraph (a) or (c) of Article 8(1) of that Order,
where it considers it necessary or expedient to do so for the purpose of implementing, or facilitating the operation of, arrangements designed to secure that the prices charged in connection with the conveyance of gas through designated pipe-lines are in accordance with a common tariff which does not distinguish (whether directly or indirectly) between different parts of Northern Ireland or the extent of use of any such pipe-line.
(2) The power to modify licence conditions under sub-paragraph (a) or (b) of paragraph (1) may not be exercised more than once pursuant to the designation of any pipe-line under Article 59.
(3) The power to modify licence conditions under sub-paragraph (a) or (b) of paragraph (1) includes power to make incidental, consequential or transitional modifications.
(4) Before making modifications under this Article the Department or the Authority shall consult the holder of any licence being modified and such other persons as it considers appropriate.
(5) Any modification of part of a standard condition of a licence under paragraph (1)(a) shall not prevent any other part of the condition from continuing to be regarded as a standard condition for the purposes of Part II of the Gas Order.
(6) Where at any time the Department or the Authority modifies under paragraph (1)(b) the standard conditions of licences under sub-paragraph (a) or (c) of Article 8(1) of the Gas Order, it shall also make (as nearly as may be) the same modifications of those conditions for the purposes of their incorporation in licences of that type granted after that time.
(7) Where the Department or the Authority makes any modifications under this Article it shall publish those modifications in such manner as it considers appropriate.
