This section applies where WRA has approved the carrying out of restoration work at an authorised landfill site.

The operator of the site may apply in writing to WRA for the variation of the approval; and section 30 applies to an application for a variation as it applies to an application for an approval.

WRA may vary the approval on its own initiative if satisfied that the variation is necessary to ensure that the approval relates only to restoration work required by a condition of an environmental permit or planning permission relating to the site.

If WRA varies an approval on its own initiative, it must issue a notice setting out the details of the variation to the operator of the authorised landfill site.

The variation of an approval does not affect the application of section 29 to restoration work carried out in accordance with the approval before it was varied.
