Section 49 – Final certificate
Where a controlled reservoir is being constructed or altered, except where it is being discontinued or abandoned, subsection (1) requires the construction engineer to issue a final certificate within 28 days of being satisfied that the reservoir is sound and satisfactory and may be used safely for the collection and storage of water.
Where the final certificate relates to a high or medium consequence reservoir and the construction engineer considers that an early inspection is required, subsection (2)(b) requires the final certificate to state when an early inspection should take place. Subsection (2)(c) requires the final certificate to specify any matter that the construction engineer considers should be monitored by the supervising engineer until the first or next inspection of the reservoir is undertaken. Subsection (2)(d) requires the final certificate to impose requirements (as specified in subsection (7)) that the water level must not exceed the level specified in the certificate, that the reservoir manager must ensure that the specified level is not exceeded and any other requirements the engineer considers appropriate as to the manner in which water levels may be increased or decreased.
Subsection (3) requires the construction engineer of a controlled reservoir which is being discontinued, to issue a final certificate to the reservoir manager within 28 days of being satisfied that the discontinuance has been safely completed, that the resulting structure or area is incapable of holding 10,000 cubic metres of water above the natural level of any part of the surrounding land and that the resulting structure or area is sound and satisfactory and may safely be used for the collection and storage of water.
A final certificate, on discontinuance, must state that the construction engineer is satisfied as to all these matters and must also specify any requirements the construction engineer considerers appropriate as regards water levels in the reservoir.
Subsection (5) deals with a reservoir being abandoned; the construction engineer must issue a final certificate to the reservoir manager within 28 days of being satisfied that the abandonment has been safely completed and that the resulting structure or area is incapable of filling with water above the natural level of any part of the surrounding land.
Subsection (6) requires that the final certificate must state that the construction engineer is satisfied as to all of these matters.
Subsection (8) requires the construction engineer to give the Department a copy of the final certificate within 28 days of issuing it. If a final certificate has not been issued within 5 years of the issue of the preliminary certificate, subsection (9) requires the construction engineer to give the reservoir manager a written explanation of the reasons why within 28 days of the expiry of the 5 year period. Subsection (9)(b) requires the construction engineer to give the reservoir manager a written explanation of the reasons at 12 months intervals thereafter, until the final certificate is issued. Subsection (9)(c) requires the construction engineer to send each of the written statements to the Department within 28 days of giving them.
