Alterations to the waterway
92.—(1) If during the construction of a specified work or a protective work or during a period of twenty four (24) months after the completion of those works any alterations or additions, either permanent or temporary, to the waterway are reasonably necessary in consequence of the construction of the specified work or the protective work in order to avoid detriment, and the Canal & River Trust gives to the undertaker reasonable notice of its intention to carry out such alterations or additions (which must be specified in the notice), the undertaker must pay to the Canal & River Trust the reasonable costs of those alterations or additions including, in respect of any such alterations or additions as are to be permanent, a capitalised sum representing the increase of the costs which may be expected to be reasonably incurred by the Canal & River Trust in maintaining, working and, when necessary, renewing any such alterations or additions.
(2) If the cost of maintaining, working or renewing the waterway is reduced in consequence of any such alterations or additions a capitalised sum representing such saving is to be set off against any sum payable by the undertaker to the Canal & River Trust under this paragraph.
(3) For the avoidance of doubt, while the Canal & River Trust may undertake works under this paragraph, including works required to make safe the area, the Canal & River Trust may not undertake any works to the pipeline, or works that may endanger the pipeline, itself under this paragraph.
