Regulation 8 Declarations of calorific value
A public gas transporter shall not make or adopt any declaration of calorific value in respect of an area within an authorised area of the transporter in respect of which he has made or adopted no previous declaration unless he has given to the Director and to each relevant licence holder who is a gas shipper two months' notice of his intention to do so and the notice is accompanied by a map (drawn to an appropriate scale) delineating the area to which the notice relates.
Where a public gas transporter makes or adopts a declaration of calorific value in respect of the area delineated in a notice given under paragraph (1) above, he shall do so at such times and in such manner as the Director may direct.
A public gas transporter shall publish as soon as practicable any declaration of calorific value made or adopted by him, or any revocation of such a declaration, in such newspapers as are calculated to ensure that the declaration or revocation is circulated throughout the area to which the declaration relates.
No declaration shall take effect until the declaration has been published in accordance with paragraph (3) above.
