19. (1) Before submitting a draft Plan variation to the Executive, the Authority shall cause to be published in the Gazette, and in a daily newspaper, a notice—
(a) stating that copies of the draft Plan variation and the background papers are available for public inspection and purchase during a specified period of not less than 21 days at specified places;
(b) inviting interested persons to submit written comments about the draft variation to the Authority at a specified address and within a period of not less than 21 days;
(c) stating the effect of sections 9 and 11; and
(d) specifying, for the purpose of paragraph 9 (1) (b), the maximum period (being a period not exceeding 1 year) during which the draft variation is to have an interim effect.
(2) The Authority shall make copies of the draft Plan variation and the background papers available for public inspection and purchase during office hours during the period, and at the places, specified in the notice.
(3) The Authority may, on request by a person who has provided written comments in relation to a draft Plan variation, exclude from the copies of the draft variation, or the background papers relating to the draft variation, that are made available for public inspection or purchase pursuant to subsection (2) information which would identify the person if, in the opinion of the Authority based on reasonable grounds, it would not be in the public interest for the information to be published.
(4) Where, in the opinion of the Authority based on reasonable grounds, it would not be in the public interest for part of a draft Plan variation, or a part of a background paper relating to a draft Plan variation, to be published, the Authority shall cause that part to be excluded from each copy of the draft variation or the background paper made available for public inspection or purchase pursuant to subsection (2).
(5) Where part of a draft Plan variation or a background paper is excluded from the copies of the draft variation or paper made available for public inspection or purchase pursuant to subsection (2), each copy so made available shall include a statement to the effect that an unspecified part of the draft variation or paper has been excluded in the public interest.
(6) Where, on application by the Authority, the Executive is satisfied that a draft Plan variation—
(a) has the sole purpose of correcting a formal error in the Plan; or
(b) would, if approved, not affect the rights of any person in a manner prejudicial to that person;
it may, by instrument, relieve the Authority of the necessity for complying with subsections (1) and (2) in relation to the draft variation.
(7) Where, pursuant to an instrument under subsection (6), the Authority does not comply with subsections (1) and (2) in relation to a draft Plan variation it shall obtain such information about the public attitudes to the draft variation as is reasonable in the circumstances.
