Paragraph 9

(1)

This paragraph applies in relation to any siltation or scouring of the River Thames which is wholly or partly caused by a specified work during the period beginning with the start of the carrying out or construction of that work and ending with the expiration of 10 years after the date on which it is completed.

(2)

If—

(a)

any part of the River Thames becomes subject to siltation or scouring;

(b)

such siltation and scouring is siltation and scouring to which this paragraph applies; and

(c)

for the safety of navigation or in the interest of persons using the River Thames or for the protection of works in the River Thames, such siltation and scouring should in the reasonable opinion of the appropriate authority be removed or made good,

DLRL shall pay to the appropriate authority (in the manner set out in sub-paragraph (4)) any additional expense to which the appropriate authority may reasonably be put in dredging the River Thames to remove the siltation or in making good the scouring, in so far as (in either case) it is attributable to the specified work.

(3)

DLRL shall pay to the appropriate authority the costs reasonably incurred by them which they would not otherwise have incurred in establishing whether siltation or scouring to which this paragraph applies has occurred.

(4)

DLRL shall, on application by the appropriate authority, make to them one or more interim payments on account of any sums required to be paid under sub-paragraph (2), being payments of such amounts and made at such times as are reasonable for meeting the current expenditure of the appropriate authority in removing the siltation or making good the scouring.
