Preliminary certificate
47.—(1) Where the construction engineer is satisfied that the reservoir may safely be filled (wholly or partially) with water or that the level of water should be reduced, the engineer must, as soon as is reasonably practicable after being so satisfied, give the reservoir manager a preliminary certificate.
(2) A preliminary certificate must—
(a)specify a level (the “specified level”) that water in the reservoir must not exceed,
(b)require the reservoir manager to ensure that the level of water does not exceed the specified level,
(c)specify any requirement the engineer considers is appropriate as to the manner in which the level of water in the reservoir may be increased or decreased.
(3) A construction engineer must, not later than 28 days after giving a preliminary certificate, give the Department a copy of it.
(4) A subsequent preliminary certificate applicable to the reservoir replaces any previous preliminary certificate applicable to the reservoir in respect of the relevant works.
(5) A preliminary certificate ceases to have effect on the issue of the final certificate applicable to the reservoir in respect of those works.
