(3) Before revoking or permanently varying a permission under paragraph (2)—

(a)the regulator shall serve notice of the proposed revocation or variation—

(i)on the persons listed in paragraph (4); and

(ii)in accordance with the provisions of paragraph (5);

and

(b)the regulator may request the owner or the holder of the permission, or of the part of the permission affected, as the case may be, to provide by a specified date, such additional information as may be required, in order that the regulator may establish the extent to which the proposed revocation or variation is likely to be effective to protect the environment from any significant adverse effects which would otherwise be caused by the dredging authorised by the permission (“the additional information”).

(4) The persons mentioned in paragraph (3)(a)(i) are—

(a)the owner and any holder of the permission or the part affected, as the case may be;

(b)the appropriate consultation bodies; and

(c)any other person (including any non-governmental organisation promoting environmental protection in marine waters) who is likely to have an interest in the application or whom the regulator considers is likely to be affected by the revocation or variation.

(5) The notice mentioned in paragraph (3)(a)(ii) shall—

(a)inform the recipients of the date when the proposed revocation or variation is intended to take effect under regulation 22; and

(b)specify a period, being not less than 28 days from the date of the notice (“the specified period”), within which representations may be made about the proposed revocation or variation.

(6) The regulator shall publish a copy of the notice served under paragraph (3)(a) by public advertisement.

(7) Where the regulator considers that it is necessary for the dredging to cease or the permission to be varied as soon as possible, the permission shall be suspended or the proposed variation, as the case may be, shall take effect (for the time being and pending the regulator’s decision under paragraph (11)) from the date on which the notice in accordance with paragraph (3)(a) is served on—

(a)the holder of the permission, if any, or

(b)if there is none, the owner.

(8) Where the regulator requests additional information under paragraph (3)(b), but the additional information is not provided by the date specified or within such further period as the regulator may allow, and the permission has not been suspended under paragraph (7), the permission shall be suspended.

(9) Where a permission has been suspended under paragraph (8)—

(a)if the additional information is provided to the regulator’s satisfaction within six months of the suspension, the suspension shall cease and the permission shall continue in effect;

(b)if the additional information is not so provided, the permission shall be revoked by the regulator and the regulator shall send notice of the revocation to the persons listed in paragraph (4).

(10) If, within the specified period, a person on whom notice has been served under paragraph (3)(a), or a person who has made representations in response to the advertisement published under paragraph (6), so requests, the regulator may give—

(a)to that person; and

(b)to any other person on whom notice was served under paragraph (3)(a), or who has made representations in response to the advertisement published under paragraph (6);

an opportunity to make representations (whether in person or in writing) to a person appointed by the regulator for that purpose.

(11) The regulator shall decide whether to revoke the permission or vary it permanently, having regard, in particular, to—

(a)any representations made in response to a notice served under paragraph (3)(a) or an advertisement published under paragraph (6); and

(b)if applicable, the report of any person appointed under paragraph (10).

(12) The regulator shall serve notice of the decision under paragraph (11) on any person on whom notice was served under paragraph (3)(a) and on any person who made representations in response to the advertisement published under paragraph (6), and the notice shall state—

(a)the main reasons for the decision;

(b)the main considerations on which the decision is based, including, if relevant, information about the public participation process; and

(c)that the decision may be challenged and the procedures for doing so.
