(a) that application shall be accompanied or supplemented by all such information as that authority may reasonably require; and

(b) the undertaker shall serve a copy of the application, and of any consent given on that application, on every person who—

(ii) has not agreed in writing that he need not be served with such a copy;

but, subject to subsection (4) below and without prejudice to the effect (if any) of any other contravention of the requirements of this section in relation to such an application, a failure to provide information in pursuance of the obligation to supplement such an application shall not invalidate the application.

(3) Subject to subsection (4) below, an application for a consent for the purposes of this section shall be determined—

(a) in the case of an application with respect to a particular discharge, before the end of the period of seven days beginning with the day after the application is made; and

and, subject to that subsection, where an application for any consent is required to be determined within the period specified in paragraph (a) above and is not so determined, the consent applied for shall be deemed to have been given unconditionally.

(4) Where—

(a) an undertaker which has made an application to any authority for a consent for the purposes of this section has failed to comply with its obligation under subsection (2)(a) above to supplement that application with information required by that authority; and

(b) that requirement was made by that authority at such a time before the end of the period within which that authority is required to determine the application as gave the undertaker a reasonable opportunity to provide the required information within that period,

that authority may delay his determination of the application until a reasonable time after the required information is provided.

(5) A consent for the purposes of this section may relate to a particular discharge or to discharges of a particular description and may be made subject to such reasonable conditions as may be specified by the person giving it; but a consent for those purposes shall not be unreasonably withheld.

(6) Any dispute as to whether a consent for the purposes of this section should be given or withheld, or as to whether the conditions to which any such consent is made subject are reasonable, shall be referred to the arbitration of a single arbitrator appointed by agreement between the parties to the dispute or, in default of agreement, by the President of the Institution of Civil Engineers.

(7) Where any discharge under section 165 above is made in an emergency without the consent which, if there were no emergency, would be required by virtue of this section, the undertaker which made the discharge shall, as soon as practicable after making the discharge, serve a notice which—

(a) states that the discharge has been made; and

(b) gives such particulars of the discharge and of the emergency as the persons served with the notice might reasonably require,

on every person on whom that undertaker would have been required to serve the application for that consent or any copy of that application.

(9) Nothing in this section shall require any consent to be obtained, or any notice to be served, in respect of any discharge if the requirements of section 34 of the M1 Water Act 1945 (temporary discharges into watercourses) in relation to that discharge had been satisfied before 1st September 1989.
