Additional requirements for public notification.
249.—(1) Where any provision of this Act requires notice to be given in one or more newspapers circulating in the area of a planning authority, the planning authority may, in addition to the requirements of the particular provision and to the extent they consider appropriate, give the notice or draw the attention of the public to the notice through other forms of media including the broadcast media and the use of electronic forms for the provision of information.
(2) Where any provision of this Act requires notice to be given to any person who has made representations, submissions or observations to a planning authority, the planning authority may dispense with that requirement where—
(a) a large number of representations, submissions or observations are made to the planning authority as part of an organised campaign, or
(b) it is not possible to readily ascertain with certainty the full name and address of those persons who made the representations, submissions or observations,
provided that the authority uses some other means of giving notice to the public that the authority is satisfied can adequately draw the attention of the public to that notice including, in the case of an organised campaign referred to in paragraph (a), giving notice to any person who, in the opinion of the planning authority, organised the campaign.
