66.Section 17 provides that an additional full assessment must be carried out and a report of that assessment must be produced and published by the Authority, as soon as practicable, if the Authority considers such an assessment necessary in relation to the relevant tip: (a) because of a change in circumstances; or (b) because information is available that was not taken into account when a full assessment was last carried out in relation to the tip. As is the case for full assessment reports of an unregistered tip under section 16, the Authority may publish the report in a redacted form.
67.The Authority may, for example, decide to carry out an additional full assessment of a disused tip that is already on the register if it learns that drainage infrastructure under the tip has collapsed since the tip was last subject to a full assessment. Equally, the Authority may decide to carry out a full assessment of a registered tip if it receives information that suggests the tip no longer meets the criteria for registration.
