Alterations of valuation lists consequential on adjustment of cumulo-value
4(1)Where the cumulo-value for an undertaking has been adjusted under paragraph 3 of this Schedule, that cumulo-value as so adjusted shall be apportioned among rating districts in which water hereditaments of the undertaking are situated, and the valuation officer shall make proposals for such alterations of valuation lists as are requisite for increasing or decreasing, as the case may require, the rateable values of the water hereditaments of the undertaking to accord with the apportionment.
(2)Any such proposals shall be made not later than three months before the beginning of the first relevant rate period, and in relation to such proposals section 79(1) of this Act shall have effect as if after the words " commencement of " there were inserted the words " the year immediately following ".
(3)Where the valuation officer transmits copies of any proposals under this paragraph, he shall transmit with them particulars of the manner in which the adjusted cumulo-value has been apportioned among rating districts so as to produce the alterations in valuation lists which are the subject of the proposals ; and effect shall not be given to objections to the proposals on any grounds other than the grounds that the apportionment was not properly made.
